Standardization
–
It can also facilitate commoditization of formerly custom processes. This view includes the case of spontaneous standardization processes, to de facto standards. Standard weights and measures were developed by the Indus Valley Civilisation, weights existed in multiples of a standard weight and in categories. Technical standardisation enabled gauging devices to be used in angular measurement and measurement for construction. Uniform units of length were used in the planning of such as Lothal, Surkotada, Kalibangan, Dolavira, Harappa. The weights and measures of the Indus civilisation also reached Persia and Central Asia, Standardisation is also related to Processes. In view of large variations in units related to Civil, Electrical and other Engineering streams, engineers united to overcome the situation and this association later on gave birth to ISO in 1950. ISO stands for International Organisation for Standardisation and this voluntary organisation is solely dedicated to standardisation and makes standards related to it. Certification as per ISO norms is popular all across world, henry Maudslay developed the first industrially practical screw-cutting lathe in 1800. This allowed for the standardisation of screw thread sizes for the first time, before this, screw threads were usually made by chipping and filing. Nuts were rare, metal screws, when made at all, were usually for use in wood, metal bolts passing through wood framing to a metal fastening on the other side were usually fastened in non-threaded ways. This was an advance in workshop technology. Maudslays work, as well as the contributions of other engineers, accomplished a modest amount of industry standardization, joseph Whitworths screw thread measurements were adopted as the first national standard by companies around the country in 1841. It came to be known as the British Standard Whitworth, and was adopted in other countries. This new standard specified a 55° thread angle and a depth of 0. 640327p and a radius of 0. 137329p. The thread pitch increased with diameter in steps specified on a chart, an example of the use of the Whitworth thread is the Royal Navys Crimean War gunboats. These were the first instance of mass-production techniques being applied to marine engineering, American Unified Coarse was originally based on almost the same imperial fractions. The Unified thread angle is 60° and has flattened crests, thread pitch is the same in both systems except that the thread pitch for the 1⁄2 in bolt is 12 threads per inch in BSW versus 13 tpi in the UNC

United States federal government
–
The Federal Government of the United States is the national government of the United States, a republic in North America, composed of 50 states, one district, Washington, D. C. and several territories. The federal government is composed of three branches, legislative, executive, and judicial, whose powers are vested by the U. S. Constitution in the Congress, the President, and the courts, including the Supreme Court. The powers and duties of these branches are defined by acts of Congress. The full name of the republic is United States of America, no other name appears in the Constitution, and this is the name that appears on money, in treaties, and in legal cases to which it is a party. The terms Government of the United States of America or United States Government are often used in documents to represent the federal government as distinct from the states collectively. In casual conversation or writing, the term Federal Government is often used, the terms Federal and National in government agency or program names generally indicate affiliation with the federal government. Because the seat of government is in Washington, D. C, Washington is commonly used as a metonym for the federal government. The outline of the government of the United States is laid out in the Constitution, the government was formed in 1789, making the United States one of the worlds first, if not the first, modern national constitutional republics. The United States government is based on the principles of federalism and republicanism, some make the case for expansive federal powers while others argue for a more limited role for the central government in relation to individuals, the states or other recognized entities. For example, while the legislative has the power to create law, the President nominates judges to the nations highest judiciary authority, but those nominees must be approved by Congress. The Supreme Court, in its turn, has the power to invalidate as unconstitutional any law passed by the Congress and these and other examples are examined in more detail in the text below. The United States Congress is the branch of the federal government. It is bicameral, comprising the House of Representatives and the Senate, the House currently consists of 435 voting members, each of whom represents a congressional district. The number of each state has in the House is based on each states population as determined in the most recent United States Census. All 435 representatives serve a two-year term, each state receives a minimum of one representative in the House. There is no limit on the number of terms a representative may serve, in addition to the 435 voting members, there are six non-voting members, consisting of five delegates and one resident commissioner. In contrast, the Senate is made up of two senators from each state, regardless of population, there are currently 100 senators, who each serve six-year terms

American National Standards Institute
–
The organization also coordinates U. S. standards with international standards so that American products can be used worldwide. ANSI accredits standards that are developed by representatives of other organizations, government agencies, consumer groups, companies. These standards ensure that the characteristics and performance of products are consistent, that use the same definitions and terms. ANSI also accredits organizations that carry out product or personnel certification in accordance with requirements defined in international standards, the organizations headquarters are in Washington, DC. ANSIs operations office is located in New York City, the ANSI annual operating budget is funded by the sale of publications, membership dues and fees, accreditation services, fee-based programs, and international standards programs. ANSI was originally formed in 1918, when five engineering societies, in 1928, the AESC became the American Standards Association. In 1966, the ASA was reorganized and became United States of America Standards Institute, the present name was adopted in 1969. At the behest of the AIEE, they invited the U. S. government Departments of War, Navy, according to Adam Stanton, the first permanent secretary and head of staff in 1919, AESC started as an ambitious program and little else. Staff for the first year consisted of one executive, Clifford B, lePage, who was on loan from a founding member, ASME. An annual budget of $7,500 was provided by the founding bodies, aNSIs members are government agencies, organizations, corporations, academic and international bodies, and individuals. In total, the Institute represents the interests of more than 125,000 companies and 3.5 million professionals, though ANSI itself does not develop standards, the Institute oversees the development and use of standards by accrediting the procedures of standards developing organizations. ANSI accreditation signifies that the used by standards developing organizations meet the Institutes requirements for openness, balance, consensus. Voluntary consensus standards quicken the market acceptance of products while making clear how to improve the safety of products for the protection of consumers. There are approximately 9,500 American National Standards that carry the ANSI designation, the Institute is the official U. S. S. ANSI participates in almost the entire program of both the ISO and the IEC, and administers many key committees and subgroups. In many instances, U. S. standards are taken forward to ISO and IEC, through ANSI or the USNC, in 2009, ANSI and the National Institute of Standards and Technology formed the Nuclear Energy Standards Coordination Collaborative. NESCC is a joint initiative to identify and respond to the current need for standards in the nuclear industry. The ASA photographic exposure system, originally defined in ASA Z38.2.1 and ASA PH2.5, together with the DIN system, became the basis for the ISO system, a standard for the set of values used to represent characters in digital computers

Institute of Electrical and Electronics Engineers
–
The Institute of Electrical and Electronics Engineers is a professional association with its corporate office in New York City and its operations center in Piscataway, New Jersey. It was formed in 1963 from the amalgamation of the American Institute of Electrical Engineers, today, it is the worlds largest association of technical professionals with more than 400,000 members in chapters around the world. Its objectives are the educational and technical advancement of electrical and electronic engineering, telecommunications, computer engineering, IEEE stands for the Institute of Electrical and Electronics Engineers. The association is chartered under this full legal name, IEEEs membership has long been composed of engineers and scientists. For this reason the organization no longer goes by the name, except on legal business documents. The IEEE is dedicated to advancing technological innovation and excellence and it has about 430,000 members in about 160 countries, slightly less than half of whom reside in the United States. The major interests of the AIEE were wire communications and light, the IRE concerned mostly radio engineering, and was formed from two smaller organizations, the Society of Wireless and Telegraph Engineers and the Wireless Institute. After World War II, the two became increasingly competitive, and in 1961, the leadership of both the IRE and the AIEE resolved to consolidate the two organizations. The two organizations merged as the IEEE on January 1,1963. The IEEE is incorporated under the Not-for-Profit Corporation Law of the state of New York and it was formed in 1963 by the merger of the Institute of Radio Engineers and the American Institute of Electrical Engineers. The IEEE serves as a publisher of scientific journals and organizer of conferences, workshops. IEEE develops and participates in activities such as accreditation of electrical engineering programs in institutes of higher learning. The IEEE logo is a design which illustrates the right hand grip rule embedded in Benjamin Franklins kite. IEEE has a dual complementary regional and technical structure – with organizational units based on geography and it manages a separate organizational unit which recommends policies and implements programs specifically intended to benefit the members, the profession and the public in the United States. The IEEE includes 39 technical Societies, organized around specialized technical fields, the IEEE Standards Association is in charge of the standardization activities of the IEEE. The IEEE History Center became an organization to the Engineering. The new ETHW is an effort by various engineering societies as a formal repository of topic articles, oral histories, first-hand histories, Landmarks + Milestones. The IEEE History Center is annexed to Stevens University Hoboken, NJ, in 2016, the IEEE acquired GlobalSpec, adding the provision of engineering data for a profit to its organizational portfolio

International Organization for Standardization
–
The International Organization for Standardization is an international standard-setting body composed of representatives from various national standards organizations. Founded on 23 February 1947, the organization promotes worldwide proprietary and it is headquartered in Geneva, Switzerland, and as of March 2017 works in 162 countries. It was one of the first organizations granted general consultative status with the United Nations Economic, ISO, the International Organization for Standardization, is an independent, non-governmental organization, the members of which are the standards organizations of the 162 member countries. It is the worlds largest developer of international standards and facilitates world trade by providing common standards between nations. Nearly twenty thousand standards have been set covering everything from manufactured products and technology to food safety, use of the standards aids in the creation of products and services that are safe, reliable and of good quality. The standards help businesses increase productivity while minimizing errors and waste, by enabling products from different markets to be directly compared, they facilitate companies in entering new markets and assist in the development of global trade on a fair basis. The standards also serve to safeguard consumers and the end-users of products and services, the three official languages of the ISO are English, French, and Russian. The name of the organization in French is Organisation internationale de normalisation, according to the ISO, as its name in different languages would have different abbreviations, the organization adopted ISO as its abbreviated name in reference to the Greek word isos. However, during the meetings of the new organization, this Greek word was not invoked. Both the name ISO and the logo are registered trademarks, the organization today known as ISO began in 1926 as the International Federation of the National Standardizing Associations. ISO is an organization whose members are recognized authorities on standards. Members meet annually at a General Assembly to discuss ISOs strategic objectives, the organization is coordinated by a Central Secretariat based in Geneva. A Council with a membership of 20 member bodies provides guidance and governance. The Technical Management Board is responsible for over 250 technical committees, ISO has formed joint committees with the International Electrotechnical Commission to develop standards and terminology in the areas of electrical and electronic related technologies. Information technology ISO/IEC Joint Technical Committee 1 was created in 1987 to evelop, maintain, ISO has three membership categories, Member bodies are national bodies considered the most representative standards body in each country. These are the members of ISO that have voting rights. Correspondent members are countries that do not have their own standards organization and these members are informed about ISOs work, but do not participate in standards promulgation. Subscriber members are countries with small economies and they pay reduced membership fees, but can follow the development of standards

NOAA
–
The National Oceanic and Atmospheric Administration is an American scientific agency within the United States Department of Commerce focused on the conditions of the oceans and the atmosphere. NOAA warns of dangerous weather, charts seas, guides the use and protection of ocean and coastal resources, and conducts research to improve understanding and stewardship of the environment. In addition to its employees, over 11,000 as of 2015, NOAA research. NOAA plays several roles in society, the benefits of which extend beyond the U. S. economy and into the larger global community. NOAA supplies information to its customers and partners pertaining to the state of the oceans and this is clearly manifest in the production of weather warnings and forecasts through the National Weather Service, but NOAAs information products extend to climate, ecosystems, and commerce as well. A Provider of Environmental Stewardship Services, NOAA is also the steward of U. S. coastal and marine environments. A Leader in Applied Scientific Research, the five fundamental activities are, Monitoring and observing Earth systems with instruments and data collection networks. Understanding and describing Earth systems through research and analysis of that data, assessing and predicting the changes of these systems over time. Engaging, advising, and informing the public and partner organizations with important information, managing resources for the betterment of society, economy and environment. NOAA formed a conglomeration of several existing agencies that were among the oldest in the federal government, NOAA was established within the Department of Commerce via the Reorganization Plan No.4 of 1970. In 2007 NOAA celebrated 200 years of service with its ties to the United States Coast, the NOAA Commissioned Officer Corps is a uniformed service of men and women who operate NOAA ships and aircraft, and serve in scientific and administrative posts. And in addition more than a dozen staff offices, including the Office of the Federal Coordinator for Meteorology, the NOAA Central Library and this is done through a collection of national and regional centers,13 river forecast centers, and more than 120 local weather forecast offices. They are charged with issuing weather and river forecasts, advisories, watches and they issue more than 734,000 weather and 850,000 river forecasts, and more than 45,000 severe weather warnings annually. NOAA data is relevant to the issues of global warming. The NWS operates NEXRAD, a network of Doppler weather radars which can detect precipitation. Many of their products are broadcast on NOAA Weather Radio, a network of transmitters that broadcasts weather forecasts, severe weather statements, watches. The National Ocean Service focuses on ensuring that ocean and coastal areas are safe, healthy, in 1960 TIROS-1, NOAAs first owned and operated geostationary satellite was launched. Since 1966 NESDIS has managed polar orbiting satellites and since 1974 it has operated geosynchronous satellites, in 1979 NOAAs first polar-orbiting environmental satellite was launched

Data Encryption Standard
–
The Data Encryption Standard is a symmetric-key algorithm for the encryption of electronic data. Although now considered insecure, it was influential in the advancement of modern cryptography. The publication of an NSA-approved encryption standard simultaneously resulted in its quick international adoption, controversies arose out of classified design elements, a relatively short key length of the symmetric-key block cipher design, and the involvement of the NSA, nourishing suspicions about a backdoor. The intense academic scrutiny the algorithm received over time led to the understanding of block ciphers. DES is now considered to be insecure for many applications and this is mainly due to the 56-bit key size being too small, in January 1999, distributed. net and the Electronic Frontier Foundation collaborated to publicly break a DES key in 22 hours and 15 minutes. There are also some analytical results which demonstrate theoretical weaknesses in the cipher, the algorithm is believed to be practically secure in the form of Triple DES, although there are theoretical attacks. The cipher has been superseded by the Advanced Encryption Standard, furthermore, DES has been withdrawn as a standard by the National Institute of Standards and Technology. Some documentation makes a distinction between DES as a standard and DES as an algorithm, referring to the algorithm as the DEA, the origins of DES go back to the early 1970s. Accordingly, on 15 May 1973, after consulting with the NSA, none of the submissions, however, turned out to be suitable. A second request was issued on 27 August 1974 and this time, IBM submitted a candidate which was deemed acceptable—a cipher developed during the period 1973–1974 based on an earlier algorithm, Horst Feistels Lucifer cipher. On 17 March 1975, the proposed DES was published in the Federal Register, public comments were requested, and in the following year two open workshops were held to discuss the proposed standard. The suspicion was that the algorithm had been weakened by the intelligence agency so that they—but no-one else—could easily read encrypted messages. Alan Konheim commented, We sent the S-boxes off to Washington and they came back and were all different. The United States Senate Select Committee on Intelligence reviewed the NSAs actions to determine whether there had been any improper involvement, however, it also found that NSA did not tamper with the design of the algorithm in any way. Another member of the DES team, Walter Tuchman, stated We developed the DES algorithm entirely within IBM using IBMers, the NSA did not dictate a single wire. In contrast, a declassified NSA book on cryptologic history states, the first offerings were disappointing, so NSA began working on its own algorithm. Then Howard Rosenblum, deputy director for research and engineering, discovered that Walter Tuchman of IBM was working on a modification to Lucifer for general use, NSA gave Tuchman a clearance and brought him in to work jointly with the Agency on his Lucifer modification. And NSA worked closely with IBM to strengthen the algorithm against all except brute force attacks and to strengthen substitution tables, conversely, NSA tried to convince IBM to reduce the length of the key from 64 to 48 bits

Advanced Encryption Standard
–
AES is a subset of the Rijndael cipher developed by two Belgian cryptographers, Vincent Rijmen and Joan Daemen, who submitted a proposal to NIST during the AES selection process. Rijndael is a family of ciphers with different key and block sizes, for AES, NIST selected three members of the Rijndael family, each with a block size of 128 bits, but three different key lengths,128,192 and 256 bits. AES has been adopted by the U. S. government and is now used worldwide and it supersedes the Data Encryption Standard, which was published in 1977. The algorithm described by AES is an algorithm, meaning the same key is used for both encrypting and decrypting the data. In the United States, AES was announced by the NIST as U. S. FIPS PUB197 on November 26,2001. This announcement followed a five-year standardization process in which fifteen competing designs were presented and evaluated, AES became effective as a federal government standard on May 26,2002 after approval by the Secretary of Commerce. AES is included in the ISO/IEC 18033-3 standard, unlike its predecessor DES, AES does not use a Feistel network. AES is a variant of Rijndael which has a block size of 128 bits. By contrast, the Rijndael specification per se is specified with block and key sizes that may be any multiple of 32 bits, both with a minimum of 128 and a maximum of 256 bits. AES operates on a 4 ×4 column-major order matrix of bytes, termed the state, most AES calculations are done in a particular finite field. For instance, if there are 16 bytes, b 0, b 1, the number of cycles of repetition are as follows,10 cycles of repetition for 128-bit keys. 12 cycles of repetition for 192-bit keys,14 cycles of repetition for 256-bit keys. Each round consists of processing steps, each containing four similar but different stages. A set of rounds are applied to transform ciphertext back into the original plaintext using the same encryption key. KeyExpansions—round keys are derived from the key using Rijndaels key schedule. AES requires a separate 128-bit round key block for each round plus one more, initialRound AddRoundKey—each byte of the state is combined with a block of the round key using bitwise xor. Rounds SubBytes—a non-linear substitution step where each byte is replaced with another according to a lookup table, shiftRows—a transposition step where the last three rows of the state are shifted cyclically a certain number of steps. MixColumns—a mixing operation which operates on the columns of the state, AddRoundKey Final Round SubBytes ShiftRows AddRoundKey

Nomenclature of Territorial Units for Statistics
–
The Classification of Territorial Units for Statistics is a geocode standard for referencing the subdivisions of countries for statistical purposes. The standard is developed and regulated by the European Union, a NUTS code begins with a two-letter code referencing the country, which is identical to the ISO 3166-1 alpha-2 code. The subdivision of the country is referred to with one number. A second or third level is referred to with another number each. Each numbering starts with 1, as 0 is used for the upper level, where the subdivision has more than nine entities, capital letters are used to continue the numbering. A similar statistical system is defined for the countries and members of the European Free Trade Association. The current NUTS classification, valid from 1 January 2015, lists 98 regions at NUTS1,276 regions at NUTS2 and 1342 regions at NUTS3 level, there are three levels of NUTS defined, with two levels of local administrative units below. These were called NUTS levels 4 and 5 until July 2003, note that not all countries have every level of division, depending on their size. One of the most extreme cases is Luxembourg, which has only LAUs, NUTS regions are generally based on existing national administrative subdivisions. In countries where one or two regional subdivisions exist, or where the size of existing subdivisions is too small or too large. This may be on the first level, on the second and/or third level, the NUTS system favors existing administrative units, with one or more assigned to each NUTS level

European Union
–
The European Union is a political and economic union of 28 member states that are located primarily in Europe. It has an area of 4,475,757 km2, the EU has developed an internal single market through a standardised system of laws that apply in all member states. Within the Schengen Area, passport controls have been abolished, a monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency. The EU operates through a system of supranational and intergovernmental decision-making. The EU traces its origins from the European Coal and Steel Community, the community and its successors have grown in size by the accession of new member states and in power by the addition of policy areas to its remit. While no member state has left the EU or its antecedent organisations, the Maastricht Treaty established the European Union in 1993 and introduced European citizenship. The latest major amendment to the basis of the EU. The EU as a whole is the largest economy in the world, additionally,27 out of 28 EU countries have a very high Human Development Index, according to the United Nations Development Programme. In 2012, the EU was awarded the Nobel Peace Prize, through the Common Foreign and Security Policy, the EU has developed a role in external relations and defence. The union maintains permanent diplomatic missions throughout the world and represents itself at the United Nations, the World Trade Organization, the G7, because of its global influence, the European Union has been described as an emerging superpower. After World War II, European integration was seen as an antidote to the nationalism which had devastated the continent. 1952 saw the creation of the European Coal and Steel Community, the supporters of the Community included Alcide De Gasperi, Jean Monnet, Robert Schuman, and Paul-Henri Spaak. These men and others are credited as the Founding fathers of the European Union. In 1957, Belgium, France, Italy, Luxembourg, the Netherlands and West Germany signed the Treaty of Rome and they also signed another pact creating the European Atomic Energy Community for co-operation in developing nuclear energy. Both treaties came into force in 1958, the EEC and Euratom were created separately from the ECSC, although they shared the same courts and the Common Assembly. The EEC was headed by Walter Hallstein and Euratom was headed by Louis Armand, Euratom was to integrate sectors in nuclear energy while the EEC would develop a customs union among members. During the 1960s, tensions began to show, with France seeking to limit supranational power, Jean Rey presided over the first merged Commission. In 1973, the Communities enlarged to include Denmark, Ireland, Norway had negotiated to join at the same time, but Norwegian voters rejected membership in a referendum

National Institute of Standards and Technology
–
The National Institute of Standards and Technology is a measurement standards laboratory, and a non-regulatory agency of the United States Department of Commerce. Its mission is to promote innovation and industrial competitiveness, in 1821, John Quincy Adams had declared Weights and measures may be ranked among the necessities of life to every individual of human society. From 1830 until 1901, the role of overseeing weights and measures was carried out by the Office of Standard Weights and Measures, president Theodore Roosevelt appointed Samuel W. Stratton as the first director. The budget for the first year of operation was $40,000, a laboratory site was constructed in Washington, DC, and instruments were acquired from the national physical laboratories of Europe. In addition to weights and measures, the Bureau developed instruments for electrical units, in 1905 a meeting was called that would be the first National Conference on Weights and Measures. Quality standards were developed for products including some types of clothing, automobile brake systems and headlamps, antifreeze, during World War I, the Bureau worked on multiple problems related to war production, even operating its own facility to produce optical glass when European supplies were cut off. Between the wars, Harry Diamond of the Bureau developed a blind approach radio aircraft landing system, in 1948, financed by the Air Force, the Bureau began design and construction of SEAC, the Standards Eastern Automatic Computer. The computer went into operation in May 1950 using a combination of vacuum tubes, about the same time the Standards Western Automatic Computer, was built at the Los Angeles office of the NBS and used for research there. A mobile version, DYSEAC, was built for the Signal Corps in 1954, due to a changing mission, the National Bureau of Standards became the National Institute of Standards and Technology in 1988. Following 9/11, NIST conducted the investigation into the collapse of the World Trade Center buildings. NIST had a budget for fiscal year 2007 of about $843.3 million. NISTs 2009 budget was $992 million, and it also received $610 million as part of the American Recovery, NIST employs about 2,900 scientists, engineers, technicians, and support and administrative personnel. About 1,800 NIST associates complement the staff, in addition, NIST partners with 1,400 manufacturing specialists and staff at nearly 350 affiliated centers around the country. NIST publishes the Handbook 44 that provides the Specifications, tolerances, the Congress of 1866 made use of the metric system in commerce a legally protected activity through the passage of Metric Act of 1866. NIST is headquartered in Gaithersburg, Maryland, and operates a facility in Boulder, nISTs activities are organized into laboratory programs and extramural programs. Effective October 1,2010, NIST was realigned by reducing the number of NIST laboratory units from ten to six, nISTs Boulder laboratories are best known for NIST‑F1, which houses an atomic clock. NIST‑F1 serves as the source of the official time. NIST also operates a neutron science user facility, the NIST Center for Neutron Research, the NCNR provides scientists access to a variety of neutron scattering instruments, which they use in many research fields

U.S. state
–
A U. S. state is a constituent political entity of the United States of America. There are 50 states, which are together in a union with each other. Each state holds administrative jurisdiction over a geographic territory. Due to the shared sovereignty between each state and the government, Americans are citizens of both the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons covered by certain types of court orders. States range in population from just under 600,000 to over 39 million, four states use the term commonwealth rather than state in their full official names. States are divided into counties or county-equivalents, which may be assigned some local authority but are not sovereign. County or county-equivalent structure varies widely by state, State governments are allocated power by the people through their individual constitutions. All are grounded in principles, and each provides for a government. States possess a number of powers and rights under the United States Constitution, Constitution has been amended, and the interpretation and application of its provisions have changed. The general tendency has been toward centralization and incorporation, with the government playing a much larger role than it once did. There is a debate over states rights, which concerns the extent and nature of the states powers and sovereignty in relation to the federal government. States and their residents are represented in the federal Congress, a legislature consisting of the Senate. Each state is represented in the Senate by two senators, and is guaranteed at least one Representative in the House, members of the House are elected from single-member districts. Representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census, the Constitution grants to Congress the authority to admit new states into the Union. Since the establishment of the United States in 1776, the number of states has expanded from the original 13 to 50, alaska and Hawaii are the most recent states admitted, both in 1959. The Constitution is silent on the question of states have the power to secede from the Union. Shortly after the Civil War, the U. S. Supreme Court, in Texas v. White, as a result, while the governments of the various states share many similar features, they often vary greatly with regard to form and substance

County (United States)
–
In the United States, an administrative or political sub-division of a state is a county, which is a region having specific boundaries and usually some level of governmental authority. The term county is used in 48 U. S. states, while Louisiana and Alaska have functionally equivalent subdivisions called parishes, most counties have subdivisions which may include municipalities and unincorporated areas. Others have no divisions, or may serve as a singular consolidated city-county. Some municipalities are in multiple counties, New York City is uniquely partitioned into multiple counties/boroughs, the U. S. federal government uses the term county equivalent to describe non-county administrative or statistical areas that are comparable to counties. Alaskas Unorganized Borough is divided into 11 census areas that are equivalent to counties. As of 2013, the United States has 3,007 counties and 137 county equivalents for a total of 3,144 counties, the number of counties per state ranges from the 3 counties of Delaware to the 254 counties of Texas. Counties have significant governmental functions in all states except Rhode Island and Connecticut, the Commonwealth of Massachusetts has removed most government functions from eight of its 14 counties. The county with the largest population, Los Angeles County, counties were among the earliest units of local government established in the Thirteen Colonies that would become the United States. Virginia created the first counties in order to ease the workload in Jamestown. Americas oldest intact county court records can be found at Eastville, Virginia, in Northampton County, maryland established its first county, St. Marys, in 1637, and Massachusetts followed in 1643. When independence came, the framers of the Constitution did not provide for local governments, rather, they left the matter to the states. Subsequently, early state constitutions generally conceptualized county government as an arm of the state, in some states, these powers are partly or mostly devolved to the counties smaller divisions usually called townships, though in New York, New England and Wisconsin they are called towns. The county may or may not be able to override its townships on certain matters, the newest county in the United States is the city and county of Broomfield, Colorado, established in 2001 as a consolidated city-county. The newest county-equivalents are the Alaskan boroughs of Skagway established in 2007, Wrangell established in 2008, there are 40 consolidated city-counties in the U. S. Similarly, some of Alaskas boroughs have merged with their principal cities creating unified city-boroughs. Some such consolidations and mergers have created cities that rank among the geographically largest cities in the world, see also, #County names, regarding Louisiana. Independent cities, These are cities that legally belong to no county, Washington, D. C. outside the jurisdiction of any state, has a special status. The city of Washington comprises the entirety of the District of Columbia, when founded in 1801, the District consisted of two counties and three cities. In 1846, Alexandria County – including the then–City of Alexandria – was given back to Virginia, in 1871, the three remaining entities – the City of Washington, Georgetown City, and Washington County – were merged into a consolidated government by an act of Congress

Geographic Names Information System
–
It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names to promote the standardization of feature names, the database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited, variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a permanent, unique feature record identifier, sometimes called the GNIS identifier, the database never removes an entry, except in cases of obvious duplication. The GNIS accepts proposals for new or changed names for U. S. geographical features, the general public can make proposals at the GNIS web site and can review the justifications and supporters of the proposals. The Bureau of the Census defines Census Designated Places as a subset of locations in the National Geographic Names Database, U. S. Postal Service Publication 28 gives standards for addressing mail.

U.S. Board on Geographic Names
–
The United States Board on Geographic Names is a federal body within the United States Geological Survey, an agency of the Department of the Interior. The purpose of the board is to establish and maintain uniform usage of names throughout the federal government of the United States. The Board was created in 1890, its present form derives from a law of 1947, under the U. S. Department of the Interior, U. S. Geological Survey, National Mapping Division, the BGN was created by presidential order. Mendenhall, superintendent of the U. S. President Benjamin Harrison signed an Executive Order on September 4,1890, to this Board shall be referred all unsettled questions concerning geographic names. The decisions of the Board are to be accepted … as the authority for such matters. The Board was given authority to resolve all unsettled questions concerning geographic names, Decisions of the Board were accepted as binding by all departments and agencies of the federal government. The Board has developed principles, policies, and procedures governing the use of domestic and it also deals with the names of geographical features underseas and in Antarctica. Although its official purpose is to resolve problems and new name proposals for the federal government. Any person or organization, public or private, may make inquiries or request the Board to render decisions on proposed new names, proposed name changes. Generally, the BGN defers federal name use to comply with local usage, for example, in rare cases where a locally used name is very offensive, the BGN may decide against adoption of the local name for federal use. In federal mapping and names collection efforts, there is often a phase lag where a delay occurs in adoption of a locally used name, sometimes the delay is several decades. Volunteers in the Earth Science Corps are used to assist the U. S. Geological Survey in collecting names of geographic features. The Geographic Names Information System, developed by the BGN in cooperation with the U. S. Geological Survey, includes topographic map names, the names of books and historic maps which confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded, the BGN has members from six federal departments as well as the Central Intelligence Agency, the Government Publishing Office, the Library of Congress, and the U. S. Postal Service. The BGN rules on hundreds of naming decisions annually and stores over two million records in its databases at geonames. usgs. gov. State and local governments, and private mapping organizations usually follow the BGNs decisions, the BGN has an executive committee and two permanent committees with full authority, the 10 to 15-member Domestic Names Committee and the 8 to 10-member Foreign Names Committee. The BGN does not create a name, the BGN responds to proposals for names from federal agencies, state, local, and tribal governments. The BGN does not translate terms, but instead accurately uses foreign names in the Roman alphabet, for non-Roman languages, the BGN uses transliteration systems or creates them for less well-known languages

U.S. Census Bureau
–
The United States Census Bureau is a principal agency of the U. S. Federal Statistical System, responsible for producing data about the American people and economy. The Census Bureaus primary mission is conducting the U. S. Census every ten years, in addition to the decennial census, the Census Bureau continually conducts dozens of other censuses and surveys, including the American Community Survey, the U. S. Economic Census, and the Current Population Survey, furthermore, economic and foreign trade indicators released by the federal government typically contain data produced by the Census Bureau. The Bureaus various censuses and surveys help allocate over $400 billion in federal funds every year and help states, local communities, the Census Bureau is part of the U. S. Department of Commerce and its director is appointed by the President of the United States. The Census Bureau now conducts a population count every 10 years in years ending with a 0. Between censuses, the Census Bureau makes population estimates and projections, the Census Bureau is mandated with fulfilling these obligations, the collecting of statistics about the nation, its people, and economy. The Census Bureaus legal authority is codified in Title 13 of the United States Code, the Census Bureau also conducts surveys on behalf of various federal government and local government agencies on topics such as employment, crime, health, consumer expenditures, and housing. Within the bureau, these are known as surveys and are conducted perpetually between and during decennial population counts. The Census Bureau also conducts surveys of manufacturing, retail, service. Between 1790 and 1840, the census was taken by marshals of the judicial districts, the Census Act of 1840 established a central office which became known as the Census Office. Several acts followed that revised and authorized new censuses, typically at the 10-year intervals, in 1902, the temporary Census Office was moved under the Department of Interior, and in 1903 it was renamed the Census Bureau under the new Department of Commerce and Labor. The department was intended to consolidate overlapping statistical agencies, but Census Bureau officials were hindered by their role in the department. An act in 1920 changed the date and authorized manufacturing censuses every 2 years, in 1929, a bill was passed mandating the House of Representatives be reapportioned based on the results of the 1930 Census. In 1954, various acts were codified into Title 13 of the US Code, by law, the Census Bureau must count everyone and submit state population totals to the U. S. President by December 31 of any year ending in a zero. States within the Union receive the results in the spring of the following year, the United States Census Bureau defines four statistical regions, with nine divisions. The Census Bureau regions are widely used. for data collection, the Census Bureau definition is pervasive. Title 13 of the U. S. Code establishes penalties for the disclosure of this information, all Census employees must sign an affidavit of non-disclosure prior to employment. The Bureau cannot share responses, addresses or personal information with anyone including United States or foreign government, only after 72 years does the information collected become available to other agencies or the general public

Indigenous peoples of the Americas
–
The indigenous peoples of the Americas are the pre-Columbian peoples of the Americas and their descendants. The term Amerindian is used in Quebec, the Guianas, Indigenous peoples of the United States are commonly known as Native Americans or American Indians, and Alaska Natives. Application of the term Indian originated with Christopher Columbus, who, in his search for Asia, eventually, the Americas came to be known as the West Indies, a name still used to refer to the islands of the Caribbean Sea. This led to the blanket term Indies and Indians for the indigenous inhabitants, although some indigenous peoples of the Americas were traditionally hunter-gatherers—and many, especially in the Amazon basin, still are—many groups practiced aquaculture and agriculture. The impact of their agricultural endowment to the world is a testament to their time, although some societies depended heavily on agriculture, others practiced a mix of farming, hunting, and gathering. In some regions the indigenous peoples created monumental architecture, large-scale organized cities, chiefdoms, states, and empires. Many parts of the Americas are still populated by peoples, some countries have sizable populations, especially Belize, Bolivia, Chile, Ecuador, Greenland, Guatemala, Mexico. At least a different indigenous languages are spoken in the Americas. Some, such as the Quechuan languages, Aymara, Guaraní, Mayan languages, many also maintain aspects of indigenous cultural practices to varying degrees, including religion, social organization, and subsistence practices. Like most cultures, over time, cultures specific to many indigenous peoples have evolved to incorporate traditional aspects, some indigenous peoples still live in relative isolation from Western culture and a few are still counted as uncontacted peoples. The specifics of Paleo-Indian migration to and throughout the Americas, including the dates and routes traveled, are the subject of ongoing research. According to archaeological and genetic evidence, North and South America were the last continents in the world with human habitation. During the Wisconsin glaciation, 50–17,000 years ago, falling sea levels allowed people to move across the bridge of Beringia that joined Siberia to northwest North America. Alaska was a glacial refugium because it had low snowfall, allowing a small population to exist, the Laurentide Ice Sheet covered most of North America, blocking nomadic inhabitants and confining them to Alaska for thousands of years. Indigenous genetic studies suggest that the first inhabitants of the Americas share a single population, one that developed in isolation. The isolation of these peoples in Beringia might have lasted 10–20,000 years, around 16,500 years ago, the glaciers began melting, allowing people to move south and east into Canada and beyond. These people are believed to have followed herds of now-extinct Pleistocene megafauna along ice-free corridors that stretched between the Laurentide and Cordilleran Ice Sheets. Another route proposed involves migration - either on foot or using primitive boats - along the Pacific Northwest coast to the south, archeological evidence of the latter would have been covered by the sea level rise of more than 120 meters since the last ice age

Alaska Native
–
Alaska Natives are indigenous peoples of Alaska, United States, Iñupiat, Yupik, Aleut, Eyak, Tlingit, Haida, Tsimshian, and a number of Northern Athabaskan cultures. They are often defined by their language groups, alaskan Natives are enrolled in federally recognized Alaska Native tribal entities, who in turn belong to 13 Alaska Native Regional Corporations, who administer land and financial claims. Ancestors of the Alaska Natives are known to have migrated into the thousands of years ago. Some are descendants of a wave of migration in which people settled across the northern part of North America. They never migrated to southern areas, for this reason, genetic studies show they are not closely related to Native Americans in South America. Throughout the Arctic and northern areas, the ancestors of the Alaska Natives established varying indigenous and they developed sophisticated ways to deal with the challenging climate and environment, and cultures rooted in the place. Historic groups have been defined by their languages, which belong to several language families. Arriving from Siberia by ship in the century, Russians began to trade with Alaska Natives. New settlements around trading posts were started by Russians, including Russian Orthodox missionaries and these were the first to translate Scripture into Native languages. British and American traders generally did not reach the area until the nineteenth century, in the 21st century, the numerous congregations of Russian Orthodox Christians in Alaska are generally composed mostly of Alaska Natives. Rather than hunting the marine life, the Russians forced the Aleuts to do the work for them, as word spread of the riches in furs to be had, competition among Russian companies increased and they forced the Aleuts into slavery. Catherine the Great, who became Empress in 1763, proclaimed good will toward the Aleut, on some islands and parts of the Alaska Peninsula, groups of traders had been capable of relatively peaceful coexistence with the local inhabitants. Other groups could not manage the tensions, Russians took hostages, families were split up, and individuals were forced to leave their villages and settle elsewhere. The growing competition between the companies, merging into fewer, larger and more powerful corporations, created conflicts that aggravated the relations with the indigenous populations. Over the years, the situation became catastrophic for the natives, as the Shelikhov-Golikov Company and later Russian-American Company developed as a monopoly, it used skirmishes and systematic violence as a tool of colonial exploitation of the indigenous people. When the Aleut revolted and won victories, the Russians retaliated, killing many and destroying their boats and hunting gear. The most devastating effects were from disease, during the first two generations of Russian contact,80 percent of the Aleut population died from Eurasian infectious diseases and these were then endemic among the Europeans, but the Aleut had no immunity against the new diseases. In 1971 the United States Congress passed the Alaska Native Claims Settlement Act and it provided for the establishment of 13 Alaska Native Regional Corporations to administer those claims

Native Hawaiian
–
Native Hawaiians are the indigenous Austronesian people of the Hawaiian Islands or their descendants. Native Hawaiians trace their ancestry back to the original Polynesian settlers of Hawaii,140,652 people identified themselves as being Native Hawaiian alone. The majority of Native Hawaiians reside in the State of Hawaiʻi, and the rest are scattered among other states, especially in the American Southwest, another is that a single, extended period of settlement populated the islands. Early historians, such as Fornander and Beckwith, subscribed to this Tahitian invasion theory, king Kalakaua claimed that Paʻao was from Samoa. Some writers claim that other settlers in Hawaiʻi were forced into remote valleys by newer arrivals and they claim that stories about the Menehune, little people who built heiau and fishponds, prove the existence of ancient peoples who settled the islands before the Hawaiians. At the time of Captain Cooks arrival in 1778, the population is estimated to have been between 250,000 and 800,000, over the span of the first century after first contact, the native Hawaiians were nearly wiped out by diseases introduced to the islands. Native Hawaiians had no resistance to influenza, smallpox, measles, or whooping cough, the 1900 U. S. Census identified 37,656 residents of full or partial native Hawaiian ancestry. The 2000 U. S. Census identified 283,430 residents of Native Hawaiian or Pacific Islander ancestry, the Hawaiian language was once the primary language of the native Hawaiian people, today, native Hawaiians predominately speak the English language. A major factor for this change was an 1896 law that required that English be the medium and basis of instruction in all public. This law prevented the Hawaiian language from being taught as a second language, in spite of this, some native Hawaiians have learned ʻŌlelo as a second language. Nowadays ʻŌlelo Hawaiʻi is the language of the State of Hawaii. The Hawaiian language has been promoted for revival most recently by a program of cultural preservation enacted in 1978. Programs included the opening of Hawaiian language immersion schools, and the establishment of a Hawaiian language department at the University of Hawaiʻi at Mānoa, as a result, Hawaiian language learning has climbed among all races in Hawaiʻi. In 2006, the University of Hawaii at Hilo established a program in the Hawaiian Language. In fall 2006, they established a program in the Hawaiian Language. In addition to being the first doctoral program for the study of Hawaiian, both the masters and doctoral programs are considered by global scholars as pioneering in the revival of native languages. Hawaiian is still spoken as the language by the residents on the private island of Niʻihau. Alongside ʻŌlelo Hawaiʻi, some Maoli spoke Hawaiʻi Sign Language, little is known about the language by Western academics and efforts are being made to preserve and revitalize the language

United States Census, 2010
–
The 2010 United States Census, is the twenty-third and currently most recent United States national census. National Census Day, the day used for the census, was April 1,2010. As part of a drive to increase the accuracy,635,000 temporary enumerators were hired. The population of the United States was counted as 308,745,538, as required by the United States Constitution, the U. S. census has been conducted every 10 years since 1790. The 2000 U. S. Census was the previous census completed, participation in the U. S. Census is required by law in Title 13 of the United States Code. On January 25,2010, Census Bureau Director Robert Groves personally inaugurated the 2010 Census enumeration by counting World War II veteran Clifton Jackson, more than 120 million census forms were delivered by the U. S. Post Office beginning March 15,2010, the number of forms mailed out or hand-delivered by the Census Bureau was approximately 134 million on April 1,2010. The 2010 Census national mail participation rate was 74%, from April through July 2010, census takers visited households that did not return a form, an operation called non-response follow-up. In December 2010, the Census Bureau delivered population information to the president for apportionment, personally identifiable information will be available in 2082. The Census Bureau did not use a form for the 2010 Census. In several previous censuses, one in six households received this long form, the 2010 Census used only a short form asking ten basic questions, How many people were living or staying in this house, apartment, or mobile home on April 1,2010. Were there any additional people staying here on April 1,2010 that you did not include in Question 1, mark all that apply, Is this house, apartment, or mobile home – What is your telephone number. What is Person 1s age and Person 1s date of birth, is Person 1 of Hispanic, Latino, or Spanish origin. Does Person 1 sometimes live or stay somewhere else, the form included space to repeat some or all of these questions for up to twelve residents total. In contrast to the 2000 census, an Internet response option was not offered, detailed socioeconomic information collected during past censuses will continue to be collected through the American Community Survey. The survey provides data about communities in the United States on a 1-year or 3-year cycle, depending on the size of the community, rather than once every 10 years. A small percentage of the population on a basis will receive the survey each year. In June 2009, the U. S. Census Bureau announced that it would count same-sex married couples, however, the final form did not contain a separate same-sex married couple option

Cryptographic
–
Cryptography or cryptology is the practice and study of techniques for secure communication in the presence of third parties called adversaries. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, Applications of cryptography include ATM cards, computer passwords, and electronic commerce. Cryptography prior to the age was effectively synonymous with encryption. The originator of an encrypted message shared the decoding technique needed to recover the information only with intended recipients. The cryptography literature often uses Alice for the sender, Bob for the intended recipient and it is theoretically possible to break such a system, but it is infeasible to do so by any known practical means. The growth of technology has raised a number of legal issues in the information age. Cryptographys potential for use as a tool for espionage and sedition has led governments to classify it as a weapon and to limit or even prohibit its use. In some jurisdictions where the use of cryptography is legal, laws permit investigators to compel the disclosure of encryption keys for documents relevant to an investigation, Cryptography also plays a major role in digital rights management and copyright infringement of digital media. Until modern times, cryptography referred almost exclusively to encryption, which is the process of converting ordinary information into unintelligible text, decryption is the reverse, in other words, moving from the unintelligible ciphertext back to plaintext. A cipher is a pair of algorithms that create the encryption, the detailed operation of a cipher is controlled both by the algorithm and in each instance by a key. The key is a secret, usually a short string of characters, historically, ciphers were often used directly for encryption or decryption without additional procedures such as authentication or integrity checks. There are two kinds of cryptosystems, symmetric and asymmetric, in symmetric systems the same key is used to encrypt and decrypt a message. Data manipulation in symmetric systems is faster than asymmetric systems as they generally use shorter key lengths, asymmetric systems use a public key to encrypt a message and a private key to decrypt it. Use of asymmetric systems enhances the security of communication, examples of asymmetric systems include RSA, and ECC. Symmetric models include the commonly used AES which replaced the older DES, in colloquial use, the term code is often used to mean any method of encryption or concealment of meaning. However, in cryptography, code has a specific meaning. It means the replacement of a unit of plaintext with a code word, English is more flexible than several other languages in which cryptology is always used in the second sense above. RFC2828 advises that steganography is sometimes included in cryptology, the study of characteristics of languages that have some application in cryptography or cryptology is called cryptolinguistics

FIPS 197
–
AES is a subset of the Rijndael cipher developed by two Belgian cryptographers, Vincent Rijmen and Joan Daemen, who submitted a proposal to NIST during the AES selection process. Rijndael is a family of ciphers with different key and block sizes, for AES, NIST selected three members of the Rijndael family, each with a block size of 128 bits, but three different key lengths,128,192 and 256 bits. AES has been adopted by the U. S. government and is now used worldwide and it supersedes the Data Encryption Standard, which was published in 1977. The algorithm described by AES is an algorithm, meaning the same key is used for both encrypting and decrypting the data. In the United States, AES was announced by the NIST as U. S. FIPS PUB197 on November 26,2001. This announcement followed a five-year standardization process in which fifteen competing designs were presented and evaluated, AES became effective as a federal government standard on May 26,2002 after approval by the Secretary of Commerce. AES is included in the ISO/IEC 18033-3 standard, unlike its predecessor DES, AES does not use a Feistel network. AES is a variant of Rijndael which has a block size of 128 bits. By contrast, the Rijndael specification per se is specified with block and key sizes that may be any multiple of 32 bits, both with a minimum of 128 and a maximum of 256 bits. AES operates on a 4 ×4 column-major order matrix of bytes, termed the state, most AES calculations are done in a particular finite field. For instance, if there are 16 bytes, b 0, b 1, the number of cycles of repetition are as follows,10 cycles of repetition for 128-bit keys. 12 cycles of repetition for 192-bit keys,14 cycles of repetition for 256-bit keys. Each round consists of processing steps, each containing four similar but different stages. A set of rounds are applied to transform ciphertext back into the original plaintext using the same encryption key. KeyExpansions—round keys are derived from the key using Rijndaels key schedule. AES requires a separate 128-bit round key block for each round plus one more, initialRound AddRoundKey—each byte of the state is combined with a block of the round key using bitwise xor. Rounds SubBytes—a non-linear substitution step where each byte is replaced with another according to a lookup table, shiftRows—a transposition step where the last three rows of the state are shifted cyclically a certain number of steps. MixColumns—a mixing operation which operates on the columns of the state, AddRoundKey Final Round SubBytes ShiftRows AddRoundKey

Portable document format
–
The Portable Document Format is a file format used to present documents in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, PDF was developed in the early 1990s as a way to share computer documents, including text formatting and inline images. It was among a number of competing formats such as DjVu, Envoy, Common Ground Digital Paper, Farallon Replica, in those early years before the rise of the World Wide Web and HTML documents, PDF was popular mainly in desktop publishing workflows. Adobe Systems made the PDF specification available free of charge in 1993 and these proprietary technologies are not standardized and their specification is published only on Adobe’s website. Many of them are not supported by popular third-party implementations of PDF. So when organizations publish PDFs which use proprietary technologies, they present accessibility issues for some users. In 2014, ISO TC171 voted to deprecate XFA for ISO 32000-2, on January 9,2017, the final draft for ISO 32000-2 was published, thus reaching the approval stage. The PDF combines three technologies, A subset of the PostScript page description programming language, for generating the layout, a font-embedding/replacement system to allow fonts to travel with the documents. A structured storage system to bundle these elements and any associated content into a single file, PostScript is a page description language run in an interpreter to generate an image, a process requiring many resources. It can handle graphics and standard features of programming such as if. PDF is largely based on PostScript but simplified to remove flow control features like these, often, the PostScript-like PDF code is generated from a source PostScript file. The graphics commands that are output by the PostScript code are collected and tokenized, any files, graphics, or fonts to which the document refers also are collected. Then, everything is compressed to a single file, therefore, the entire PostScript world remains intact. PDF supports graphic transparency, PostScript does not, PostScript is an interpreted programming language with an implicit global state, so instructions accompanying the description of one page can affect the appearance of any following page. Therefore, all preceding pages in a PostScript document must be processed to determine the appearance of a given page. A PDF file is a 7-bit ASCII file, except for elements that may have binary content. A PDF file starts with a header containing the magic number, the format is a subset of a COS format. A COS tree file consists primarily of objects, of which there are eight types, Boolean values, representing true or false Numbers Strings, enclosed within parentheses, objects may be either direct or indirect

Federal Register
–
The Federal Register, abbreviated FR or sometimes Fed. Reg. is the journal of the federal government of the United States that contains government agency rules, proposed rules. It is published daily, except on federal holidays, the Federal Register is compiled by the Office of the Federal Register and is printed by the Government Publishing Office. There are no restrictions on the Federal Register, as a work of the U. S. government. In essence, the Federal Register is a way for the government to announce changes to government requirements, policies, the notice and comment process, as outlined in the Administrative Procedure Act, gives the people a chance to participate in agency rulemaking. Publication of documents in the Federal Register also constitutes constructive notice, the Federal Register is the main source for the U. S. Both proposed and final rules are published in the Federal Register, a Notice of Proposed Rulemaking typically requests public comment on a proposed rule, and provides notice of any public meetings where a proposed rule will be discussed. The public comments are considered by the government agency. The United States Government Manual is published as an edition of the Federal Register. Its focus is on programs and activities, to purchase current or back print copies of the Federal Register, one may contact the U. S. Government Publishing Office. In each issue of the Federal Register, there is a subscription page, currently, a years subscription rate within the U. S. is US$929. Each individual issue may be priced from $11 to $33 depending on its pages, virtually every law library associated with an American Bar Association–accredited law school will also have a set, as will federal depository libraries. The Federal Register has been online since 1994. Federal depository libraries within the U. S. also receive copies of the text, outside the U. S. some major libraries may also carry the Federal Register. To help federal agencies manage their dockets, the Federal Docket Management System was launched in 2005 and is the side of regulations. gov. In April 2009, Citation Technologies created a free, searchable website for Federal Register articles dating from 1996 to the present. GovPulse. us, a finalist in the Sunlight Foundations Apps for America 2, provides a web 2.0 interface to the Federal Register, including sparklines of agency activity, on July 25,2010, the Federal Register 2.0 website went live. The new website is a collaboration between the developers who created GovPulse. us, the Government Publishing Office and the National Archives, on August 1,2011, the Federal Register announced a new application programming interface to facilitate programmatic access to the Federal Register content

The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its resources. The organization has four science disciplines, concerning biology, geography, geology. The USGS is a research organization with no regulatory responsibility. The USGS is a bureau of the United States Department of the Interior, the USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, the current motto of the USGS, in use since August 1997, is science for a changing world. The agencys previous slogan, adopted on the occasion of its anniversary, was Earth Science in the Public Service. Prompted by a report from the National Academy of Sciences, the USGS was created, by a last-minute amendment and it was charged with the classification of the public lands, and examination of the geological structure, mineral resources, and products of the national domain. This task was driven by the need to inventory the vast lands added to the United States by the Louisiana Purchase in 1803, the legislation also provided that the Hayden, Powell, and Wheeler surveys be discontinued as of June 30,1879. Clarence King, the first director of USGS, assembled the new organization from disparate regional survey agencies, after a short tenure, King was succeeded in the directors chair by John Wesley Powell. Administratively, it is divided into a Headquarters unit and six Regional Units, Other specific programs include, Earthquake Hazards Program monitors earthquake activity worldwide. The National Earthquake Information Center in Golden, Colorado on the campus of the Colorado School of Mines detects the location, the USGS also runs or supports several regional monitoring networks in the United States under the umbrella of the Advanced National Seismic System. The USGS informs authorities, emergency responders, the media, and it also maintains long-term archives of earthquake data for scientific and engineering research. It also conducts and supports research on long-term seismic hazards, USGS has released the UCERF California earthquake forecast. The USGS National Geomagnetism Program monitors the magnetic field at magnetic observatories and distributes magnetometer data in real time, the USGS operates the streamgaging network for the United States, with over 7400 streamgages. Real-time streamflow data are available online, since 1962, the Astrogeology Research Program has been involved in global, lunar, and planetary exploration and mapping. USGS operates a number of related programs, notably the National Streamflow Information Program. USGS Water data is available from their National Water Information System database

ISO 3166-1
–
The official name of the standard is Codes for the representation of names of countries and their subdivisions – Part 1, Country codes. ISO 3166-1 alpha-3 – three-letter country codes which allow a visual association between the codes and the country names than the alpha-2 codes. The alphabetic country codes were first included in ISO3166 in 1974, as a widely used international standard, ISO 3166-1 is implemented in other standards and used by international organizations to allow facilitation of the exchange of goods and information. However, it is not the standard for country codes. Other country codes used by international organizations are partly or totally incompatible with ISO 3166-1. Currently 249 countries, territories, or areas of geographical interest are assigned codes in ISO 3166-1. Once a country name or territory name appears in either of two sources, it will be added to ISO 3166-1 by default. The ISO 3166/MA may reserve code elements for other entities that do not qualify for inclusion based on the above criteria, ISO 3166-1 is published officially in both English and French. For this reason, common components of names like Republic, Kingdom, United. As a consequence, for example, the United Kingdom is officially assigned the alpha-2 code GB rather than UK, based on its official name United Kingdom of Great Britain, some codes are chosen based on the native names of the countries. For example, Germany is assigned the alpha-2 code DE, based on its native name Deutschland, the following is a complete ISO 3166-1 encoding list of the countries which are assigned official codes. It is listed in order by the English short country name used by the ISO 3166/MA. Note, Each countrys alpha-2 code is linked to information about the assignment of its code elements. Besides the officially assigned codes, code elements may be expanded by using either reserved codes or user-assigned codes. Reserved code elements are codes which have become obsolete, or are required in order to enable a user application of the standard. Codes are usually reserved for countries, overseas territories, international organizations. A country is assigned new ISO 3166-1 codes if it changes its name or its territorial boundaries. In general, new codes are assigned if a country changes a significant part of its name
