The Roxborough-Manyunk section of Philadelphia is an official planning district of the Philadelphia City Planning Commission, consisting of the namesake boroughs of Roxborough and Manayunk. Geographically, the area is northwest of Center City. Today, this area consists of West Oak Lane, East Mount Airy, East Falls, West Mount Airy and Manayunk; the demographics of Roxborough-Manayunk shows that the area has a population 106,265, with 47,884 males, 58,382 females and a median age of 34
In broadcasting and radio communications, a call sign is a unique designation for a transmitter station. In the United States of America, they are used for all FCC-licensed transmitters. A call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or cryptographically encoded to disguise a station's identity; the use of call signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one telegraph line linking all railroad stations, there needed to be a way to address each one when sending a telegram. In order to save time, two-letter identifiers were adopted for this purpose; this pattern continued in radiotelegraph operation. These were not globally unique, so a one-letter company identifier was added. By 1912, the need to identify stations operated by multiple companies in multiple nations required an international standard. Merchant and naval vessels are assigned call signs by their national licensing authorities.
In the case of states such as Liberia or Panama, which are flags of convenience for ship registration, call signs for larger vessels consist of the national prefix plus three letters. United States merchant vessels are given call signs beginning with the letters "W" or "K" while US naval ships are assigned call signs beginning with "N". Both ships and broadcast stations were assigned call signs in this series consisting of three or four letters. Ships equipped with Morse code radiotelegraphy, or life boat radio sets, Aviation ground stations, broadcast stations were given four letter call signs. Maritime coast stations on high frequency were assigned three letter call signs; as demand for both marine radio and broadcast call signs grew American-flagged vessels with radiotelephony only were given longer call signs with mixed letters and numbers. Leisure craft with VHF radios may not be assigned call signs, in which case the name of the vessel is used instead. Ships in the US still wishing to have a radio license are under FCC class SA: "Ship recreational or voluntarily equipped."
Those calls follow the land mobile format of the initial letter K or W followed by 1 or 2 letters followed by 3 or 4 numbers. U. S. Coast Guard small boats have a number, shown on both bows in which the first two digits indicate the nominal length of the boat in feet. For example, Coast Guard 47021 refers to the 21st in the series of 47-foot motor lifeboats; the call sign might be abbreviated to the final two or three numbers during operations, for example: Coast Guard zero two one. Aviation mobile stations equipped with radiotelegraphy were assigned five letter call signs.. Land Stations in Aviation were assigned four letter call signs; these call signs were phased out in the 1960s when flight radio officers were no longer required on international flights. USSR kept FRO's for the Moscow-Havana run until around 2000. All signs in aviation are derived from several different policies, depending upon the type of flight operation and whether or not the caller is in an aircraft or at a ground facility.
In most countries, unscheduled general aviation flights identify themselves using the call sign corresponding to the aircraft's registration number. In this case, the call sign is spoken using the International Civil Aviation Organization phonetic alphabet. Aircraft registration numbers internationally follow the pattern of a country prefix, followed by a unique identifier made up of letters and numbers. For example, an aircraft registered as N978CP conducting a general aviation flight would use the call sign November-niner-seven-eight-Charlie-Papa. However, in the United States a pilot of an aircraft would omit saying November, instead use the name of the aircraft manufacturer or the specific model. At times, general aviation pilots might omit additional preceding numbers and use only the last three numbers and letters; this is true at uncontrolled fields when reporting traffic pattern positions or at towered airports after establishing two-way communication with the tower controller. For example, Skyhawk eight-Charlie-Papa, left base.
In most countries, the aircraft call sign or "tail number"/"tail letters" are linked to the international radio call sign allocation table and follow a convention that aircraft radio stations receive call signs consisting of five letters. For example, all British civil aircraft have a five-letter call sign beginning with the letter G. Canadian aircraft have a call sign beginning with C–F or C–G, such as C–FABC. Wing In Ground-effect vehicles in Canada are eligible to receive C–Hxxx call signs, ultralight aircraft receive C-Ixxx call signs. In days gone by American aircraft used five letter call signs, such as KH–ABC, but they were replaced prior to World War II by the current American system of civilian aircraft call signs. Radio call signs used for communication in manned spaceflight is not formalized or regulated to the same degree as for aircraft; the three nations curren
Augusta Augusta–Richmond County, is a consolidated city-county on the central eastern border of the U. S. state of Georgia. The city lies across the Savannah River from South Carolina at the head of its navigable portion. Georgia's second-largest city after Atlanta, Augusta is located in the Piedmont section of the state. According to the U. S. Census Bureau, Augusta–Richmond County had a 2017 estimated population of 197,166, not counting the unconsolidated cities of Blythe and Hephzibah, it is the 122nd largest city in the United States. The process of consolidation between the City of Augusta and Richmond County began with a 1995 referendum in the two jurisdictions; the merger was completed on July 1, 1996. Augusta is the principal city of the Augusta metropolitan area, situated in both Georgia and South Carolina on both sides of the Savannah River. In 2017 it had an estimated population of 600,151, making it the second-largest metro area in the state, it is the 93rd largest metropolitan area in the United States.
Augusta was established in 1736 and is named for Princess Augusta of Saxe-Gotha, the bride of Frederick, Prince of Wales and the mother of the British monarch George III. During the American Civil War, Augusta housed the principal Confederate powder works. Augusta's warm climate made it a major resort town of the Eastern United States in the early and mid-20th century. Internationally, Augusta is best known for hosting The Masters golf tournament each spring; the Masters brings over 200,000 visitors from across the world to the Augusta National Golf Club. Membership at Augusta National is considered to be the most exclusive in the sport of golf across the world. Augusta lies two hours east of downtown Atlanta by car via I-20; the city is home to Fort Gordon, a major U. S. Army base. In 2016, it was announced that the new National Cyber Security Headquarters would be based in Augusta, bringing as many as 10,000 cyber security specialists to the Fort Gordon area; the area along the river was long inhabited by varying cultures of indigenous peoples, who relied on the river for fish and transportation.
The site of Augusta was used by Native Americans as a place to cross the Savannah River, because of its location on the fall line. In 1735, two years after James Oglethorpe founded Savannah, he sent a detachment of troops to explore the upper Savannah River, he gave them an order to build a fort at the head of the navigable part of the river. The expedition was led by Noble Jones, who created a settlement as a first line of defense for coastal areas against potential Spanish or French invasion from the interior. Oglethorpe named the town in honor of Princess Augusta, the mother of King George III and the wife of Frederick, Prince of Wales. Oglethorpe visited Augusta in September 1739 on his return to Savannah from a perilous visit to Coweta Town, near present-day Phenix City, Alabama. There, he had met with a convention of 7,000 Native American warriors and concluded a peace treaty with them in their territories in northern and western Georgia. Augusta was the second state capital of Georgia from 1785 until 1795.
Augusta developed as a market town as the Black Belt in the Piedmont was developed for cotton cultivation. Invention of the cotton gin made processing of short-staple cotton profitable, this type of cotton was well-suited to the upland areas. Cotton plantations were worked by slave labor, with hundreds of thousands of slaves shipped from the Upper South to the Deep South in the domestic slave trade. Many of the slaves were brought from the Lowcountry, where their Gullah culture had developed on the large Sea Island cotton and rice plantations; the city experienced the Augusta Fire of 1916, which damaged 25 blocks of the town and many buildings of historical significance. As a major city in the area, Augusta was a center of activities after. In the mid-20th century, it was a site of civil rights demonstrations. In 1970 Charles Oatman, a mentally disabled teenager, was killed by his cellmates in an Augusta jail. A protest against his death broke out in a riot involving 500 people, after six black men were killed by police, each found to have been shot in the back.
The noted singer and entertainer James Brown was called in to help quell lingering tensions, which he succeeded in doing. Augusta is located on the Georgia/South Carolina border, about 150 miles east of Atlanta and 70 miles west of Columbia; the city is located at 33°28′12″N 81°58′30″W. According to the United States Census Bureau, the Augusta–Richmond County balance has a total area of 306.5 square miles, of which 302.1 square miles is land and 4.3 square miles is water. Augusta is located about halfway up the Savannah River on the fall line, which creates a number of small falls on the river; the city marks the end of a navigable waterway for the river and the entry to the Georgia Piedmont area. The Clarks Hill Dam is built on the fall line near Augusta. Farther downstream, near the border of Columbia County, is the Stevens Creek Dam, which generates hydroelectric power. Farther downstream is the Augusta Diversion Dam, which marks the beginning of the Augusta Canal and channels Savannah River waters into the canal.
As with the rest of the state, Augusta has a humid subtropical climate, with short, mild winters hot, humid summers, a wide diurnal temperature variation throughout much of the year, despite its low elevation and moisture. The monthly daily average temperature ranges from 45.4 °F in January to 81.6 °F in July.
A slogan is a memorable motto or phrase used in a clan, commercial and other context as a repetitive expression of an idea or purpose, with the goal of persuading members of the public or a more defined target group. The Oxford Dictionary of English defines a slogan as "a short and striking or memorable phrase used in advertising." A slogan has the attributes of being memorable concise and appealing to the audience. The word slogan is derived from slogorn, an Anglicisation of the Scottish Gaelic and Irish sluagh-ghairm. Slogans vary from the visual to the chanted and the vulgar, their simple rhetorical nature leaves little room for detail and a chanted slogan may serve more as social expression of unified purpose than as communication to an intended audience. George E. Shankel's research states that, "English-speaking people began using the term by 1704." The term at that time meant "the distinctive note, phrase or cry of any person or body of persons." Slogans were common throughout the European continent during the Middle Ages.
Crimmins' research suggests that brands are an valuable corporate asset, can make up a lot of a business's total value. With this in mind, if we take into consideration Keller's research, which suggests that a brand is made up of three different components; these include, name and slogan. Brands names and logos both can be changed by the way. Therefore, the slogan has a large job in portraying the brand. Therefore, the slogan should create a sense of likability in order for the brand name to be likable and the slogan message clear and concise. Dass, Kohli, & Thomas' research suggests that there are certain factors that make up the likability of a slogan; the clarity of the message the brand is trying to encode within the slogan. The slogan emphasizes the benefit of the service it is portraying; the creativity of a slogan is another factor that had a positive effect on the likability of a slogan. Lastly, leaving the brand name out of the slogan will have a positive effect on the likability of the brand itself.
Advertisers must keep into consideration these factors when creating a slogan for a brand, as it shows a brand is a valuable asset to a company, with the slogan being one of the three main components to a brands' image. The original usage refers to the usage as a clan motto among Highland clans. Marketing slogans are called taglines in the United States or straplines in the United Kingdom. Europeans use the terms baselines, claims or pay-offs. "Sloganeering" is a derogatory term for activity which degrades discourse to the level of slogans. Slogans are used to convey a message about the service or cause that it is representing, it written as a song. Slogans are used to capture the attention of the audience it is trying to reach. If the slogan is used for commercial purposes it is written to be memorable/catchy in order for a consumer to associate the slogan with the product it is representing. A slogan is part of the production aspect that helps create an image for the product, service or cause it's representing.
A slogan can be a few simple words used to form a phrase. In commercial advertising, corporations will use a slogan as part of promotional activity. Slogans can become a global way of identifying good or service, for example Nike's slogan'Just Do It' helped establish Nike as an identifiable brand worldwide. Slogans should catch the audience's attention and influence the consumer's thoughts on what to purchase; the slogan is used by companies to affect the way consumers view their product compared to others. Slogans can provide information about the product, service or cause its advertising; the language used in the slogans is essential to the message. Current words used can trigger different emotions; the use of good adjectives makes for an effective slogan. When a slogan is used for advertising purposes its goal is to sell the product or service to as many consumers through the message and information a slogan provides. A slogan's message can include information about the quality of the product.
Examples of words that can be used to direct the consumer preference towards a current product and its qualities are: good, real, great, perfect and pure. Slogans can influence. Slogans offer information to consumers in an creative way. A slogan can be used for a powerful cause; the slogan can be used to raise awareness about a current cause. A slogan should be clear with a supporting message. Slogans, when combined with action, can provide an influential foundation for a cause to be seen by its intended audience. Slogans, whether used for advertising purpose or social causes, deliver a message to the public that shapes the audiences' opinion towards the subject of the slogan. "It is well known that the text a human hears or reads constitutes 7% of the received information. As a result, any slogan possesses a support
AM broadcasting is a radio broadcasting technology, which employs amplitude modulation transmissions. It was the first method developed for making audio radio transmissions, is still used worldwide for medium wave transmissions, but on the longwave and shortwave radio bands; the earliest experimental AM transmissions began in the early 1900s. However, widespread AM broadcasting was not established until the 1920s, following the development of vacuum tube receivers and transmitters. AM radio remained the dominant method of broadcasting for the next 30 years, a period called the "Golden Age of Radio", until television broadcasting became widespread in the 1950s and received most of the programming carried by radio. Subsequently, AM radio's audiences have greatly shrunk due to competition from FM radio, Digital Audio Broadcasting, satellite radio, HD radio and Internet streaming. AM transmissions are much more susceptible than FM or digital signals are to interference, have lower audio fidelity.
Thus, AM broadcasters tend to specialise in spoken-word formats, such as talk radio, all news and sports, leaving the broadcasting of music to FM and digital stations. The idea of broadcasting — the unrestricted transmission of signals to a widespread audience — dates back to the founding period of radio development though the earliest radio transmissions known as "Hertzian radiation" and "wireless telegraphy", used spark-gap transmitters that could only transmit the dots-and-dashes of Morse code. In October 1898 a London publication, The Electrician, noted that "there are rare cases where, as Dr. Lodge once expressed it, it might be advantageous to'shout' the message, spreading it broadcast to receivers in all directions". However, it was recognized that this would involve significant financial issues, as that same year The Electrician commented "did not Prof. Lodge forget that no one wants to pay for shouting to the world on a system by which it would be impossible to prevent non-subscribers from benefiting gratuitously?"On January 1, 1902, Nathan Stubblefield gave a short-range "wireless telephone" demonstration, that included broadcasting speech and music to seven locations throughout Murray, Kentucky.
However, this was transmitted using induction rather than radio signals, although Stubblefield predicted that his system would be perfected so that "it will be possible to communicate with hundreds of homes at the same time", "a single message can be sent from a central station to all parts of the United States", he was unable to overcome the inherent distance limitations of this technology. The earliest public radiotelegraph broadcasts were provided as government services, beginning with daily time signals inaugurated on January 1, 1905, by a number of U. S. Navy stations. In Europe, signals transmitted from a station located on the Eiffel tower were received throughout much of Europe. In both the United States and France this led to a small market of receiver lines designed geared for jewelers who needed accurate time to set their clocks, including the Ondophone in France, the De Forest RS-100 Jewelers Time Receiver in the United States The ability to pick up time signal broadcasts, in addition to Morse code weather reports and news summaries attracted the interest of amateur radio enthusiasts.
It was recognized that, much like the telegraph had preceded the invention of the telephone, the ability to make audio radio transmissions would be a significant technical advance. Despite this knowledge, it still took two decades to perfect the technology needed to make quality audio transmissions. In addition, the telephone had been used for distributing entertainment, outside of a few "telephone newspaper" systems, most of which were established in Europe. With this in mind, most early radiotelephone development envisioned that the device would be more profitably developed as a "wireless telephone" for personal communication, or for providing links where regular telephone lines could not be run, rather than for the uncertain finances of broadcasting; the person credited as the primary early developer of AM technology is Canadian-born inventor Reginald Fessenden. The original spark-gap radio transmitters were impractical for transmitting audio, since they produced discontinuous pulses known as "damped waves".
Fessenden realized that what was needed was a new type of radio transmitter that produced steady "undamped" signals, which could be "modulated" to reflect the sounds being transmitted. Fessenden's basic approach was disclosed in U. S. Patent 706,737, which he applied for on May 29, 1901, was issued the next year, it called for the use of a high-speed alternator that generated "pure sine waves" and produced "a continuous train of radiant waves of uniform strength", or, in modern terminology, a continuous-wave transmitter. Fessenden began his research on audio transmissions while doing developmental work for the United States Weather Service on Cobb Island, Maryland; because he did not yet have a continuous-wave transmitter he worked with an experimental "high-frequency spark" transmitter, taking advantage of the fact that the higher the spark rate, the closer a spark-gap transmission comes to producing continuous waves. He reported that, in the fall of 1900, he transmitted speech over a distance of about 1.6 kilometers, which appears to have been the first successful audio transmission using radio signals.
However, at this time the sound was far too distorted to be commercially practical. For a time he continued working with more sophist
Frequency is the number of occurrences of a repeating event per unit of time. It is referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency; the period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency. For example: if a newborn baby's heart beats at a frequency of 120 times a minute, its period—the time interval between beats—is half a second. Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals, radio waves, light. For cyclical processes, such as rotation, oscillations, or waves, frequency is defined as a number of cycles per unit time. In physics and engineering disciplines, such as optics and radio, frequency is denoted by a Latin letter f or by the Greek letter ν or ν; the relation between the frequency and the period T of a repeating event or oscillation is given by f = 1 T.
The SI derived unit of frequency is the hertz, named after the German physicist Heinrich Hertz. One hertz means. If a TV has a refresh rate of 1 hertz the TV's screen will change its picture once a second. A previous name for this unit was cycles per second; the SI unit for period is the second. A traditional unit of measure used with rotating mechanical devices is revolutions per minute, abbreviated r/min or rpm. 60 rpm equals one hertz. As a matter of convenience and slower waves, such as ocean surface waves, tend to be described by wave period rather than frequency. Short and fast waves, like audio and radio, are described by their frequency instead of period; these used conversions are listed below: Angular frequency denoted by the Greek letter ω, is defined as the rate of change of angular displacement, θ, or the rate of change of the phase of a sinusoidal waveform, or as the rate of change of the argument to the sine function: y = sin = sin = sin d θ d t = ω = 2 π f Angular frequency is measured in radians per second but, for discrete-time signals, can be expressed as radians per sampling interval, a dimensionless quantity.
Angular frequency is larger than regular frequency by a factor of 2π. Spatial frequency is analogous to temporal frequency, but the time axis is replaced by one or more spatial displacement axes. E.g.: y = sin = sin d θ d x = k Wavenumber, k, is the spatial frequency analogue of angular temporal frequency and is measured in radians per meter. In the case of more than one spatial dimension, wavenumber is a vector quantity. For periodic waves in nondispersive media, frequency has an inverse relationship to the wavelength, λ. In dispersive media, the frequency f of a sinusoidal wave is equal to the phase velocity v of the wave divided by the wavelength λ of the wave: f = v λ. In the special case of electromagnetic waves moving through a vacuum v = c, where c is the speed of light in a vacuum, this expression becomes: f = c λ; when waves from a monochrome source travel from one medium to another, their frequency remains the same—only their wavelength and speed change. Measurement of frequency can done in the following ways, Calculating the frequency of a repeating event is accomplished by counting the number of times that event occurs within a specific time period dividing the count by the length of the time period.
For example, if 71 events occur within 15 seconds the frequency is: f = 71 15 s ≈ 4.73 Hz If the number of counts is not large, it is more accurate to measure the time interval for a predetermined number of occurrences, rather than the number of occurrences within a specified time. The latter method introduces a random error into the count of between zero and one count, so on average half a count; this is called gating error and causes an average error in the calculated frequency of Δ f = 1 2 T
A webcast is a media presentation distributed over the Internet using streaming media technology to distribute a single content source to many simultaneous listeners/viewers. A webcast may either be distributed live or on demand. Webcasting is "broadcasting" over the Internet; the largest "webcasters" include existing radio and TV stations, who "simulcast" their output through online TV or online radio streaming, as well as a multitude of Internet only "stations". Webcasting consists of providing non-interactive linear streams or events. Rights and licensing bodies offer specific "webcasting licenses" to those wishing to carry out Internet broadcasting using copyrighted material. Webcasting is used extensively in the commercial sector for investor relations presentations, in e-learning, for related communications activities. However, webcasting does not bear much, if any, relationship to web conferencing, designed for many-to-many interaction; the ability to webcast using cheap/accessible technology has allowed independent media to flourish.
There are many notable independent shows that broadcast online. Produced by average citizens in their homes they cover many interests and topics. Webcasts relating to computers and news are popular and many new shows are added regularly. Webcasting differs from podcasting in that webcasting refers to live streaming while podcasting refers to media files placed on the Internet. Webcasting is the distribution of media files through the internet; the earliest graphically-oriented web broadcasts were not streaming video, but were in fact still frames which were photographed with a web camera every few minutes while they were being broadcast live over the Internet. One of the earliest instances of sequential live image broadcasting was in 1991 when a camera was set up next to the Trojan Room in the computer laboratory of the University of Cambridge, it provided a live picture every few minutes of the office coffee pot to all desktop computers on that office's network. A couple of years its broadcasts went to the Internet, became known as the Trojan Room Coffee Pot webcam, gained international notoriety as a feature of the fledgling World Wide Web.
In 1996 an American college student and conceptual artist, Jenny Ringley, set up a web camera similar to the Trojan Room Coffee Pot's webcam in her dorm room. That webcam photographed her every few minutes while it broadcast those images live over the Internet upon a site called JenniCam. Ringley wanted to portray all aspects of her lifestyle and the camera captured her doing everything – brushing her teeth, doing her laundry, having sex with her boyfriend, her website generated millions of hits upon the Internet, became a pay site in 1998, spawned hundreds of female imitators who would use streaming video to create a new billion dollar industry called camming, brand themselves as camgirls or webcam models. One of the earliest webcast equivalent of an online concert and one of the earliest examples of webcasting itself was by Apple Computer's Webcasting Group in partnership with the entrepreneurs Michael Dorf and Andrew Rasiej. Together with David B. Pakman from Apple, they launched the Macintosh New York Music Festival from July 17–22, 1995.
This event audio webcast concerts from more than 15 clubs in New York City. Apple webcast a concert by Metallica on June 10, 1996 live from Slim's in San Francisco. In 1995, Benford E. Standley produced one of the first audio/video webcasts in history. On October 31, 1996, UK rock band Caduseus broadcast their one-hour concert from 11 pm to 12 midnight at Celtica in Machynlleth, Wales, UK – the first live streamed audio and simultaneous live streamed video multicast – around the globe to more than twenty direct "mirrors" in more than twenty countries. In September 1997, Nebraska Public Television started webcasting Big Red Wrap Up from Lincoln, Nebraska which combined highlights from every Cornhusker football game, coverage of the coaches' weekly press conferences, analysis with Nebraska sportswriters, appearances by special guests and questions and answers with viewers. On August 13, 1998, it is believed the first webcast wedding took place, between Alan K'necht and Carrie Silverman in Toronto Canada.
On October 22, 1998, the first Billy Graham Crusade was broadcast live to a worldwide audience from the Raymond James Stadium in Tampa Florida courtesy of Dale Ficken and the WebcastCenter in Pennsylvania. The live signal was broadcast via satellite to PA encoded and streamed via the BGEA website; the first teleconferenced/webcast wedding to date is believed to have occurred on December 31, 1998. Dale Ficken and Lorrie Scarangella wed on this date as they stood in a church in Pennsylvania, were married by Jerry Falwell while he sat in his office in Lynchburg, Virginia. All major broadcasters now have a webcast of their output, from the BBC to CNN to Al Jazeera to UNTV in television to Radio China, Vatican Radio, United Nations Radio and the World Service in radio. On November 4, 1994, Stef van der Ziel distributed the first live video images over the web from the Simplon venue in Groningen. On November 7, 1994, WXYC, the college radio station of the University of North Carolina at Chapel Hill became the first radio station in the world to broadcast its signal over the internet.
Translated versions including Subtitling are now possible using SMIL Synchronized Multimedia Integration Language. A wedcast of a wedding. Allows family and friends of the couple to watch the wedding in real time on the Internet, it is sometimes used for weddings in exotic locations, such as Cancun and the Riviera Maya, Hawaii or the Caribbean, for which it is expensive or difficul
