Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Liverpool
–
Liverpool is a major city and metropolitan borough in North West England.24 million people in 2011. Liverpool historically lay within the ancient hundred of West Derby in the south west of the county of Lancashire and it became a borough from 1207 and a city from 1880. In 1889 it became a county borough independent of Lancashire, Liverpool sits on the eastern side of the Mersey Estuary and its growth as a major port is paralleled by the expansion of the city throughout the Industrial Revolution. Along with general cargo, freight, raw materials such as coal and cotton, the city was also directly involved in the Atlantic slave trade. Liverpool was home to both the Cunard and White Star Line, and was the port of registry of the ocean liner RMS Titanic and others such as the RMS Lusitania, Queen Mary, and Olympic. The city celebrated its 800th anniversary in 2007, and it held the European Capital of Culture title together with Stavanger, Norway, several areas of Liverpool city centre were granted World Heritage Site status by UNESCO in 2004. The Liverpool Maritime Mercantile City includes the Pier Head, Albert Dock, tourism forms a significant part of the citys economy. Liverpool is also the home of two Premier League football clubs, Liverpool and Everton, matches between the two being known as the Merseyside derby, the world-famous Grand National horse race takes place annually at Aintree Racecourse on the outskirts of the city. The city is home to the oldest Black African community in the country. Natives of Liverpool are referred to as Liverpudlians and colloquially as Scousers, a reference to scouse, the word Scouse has also become synonymous with the Liverpool accent and dialect. Pool is a place name element in England from the Brythonic word for a pond, inlet, or pit, cognate with the modern Welsh. The derivation of the first element remains uncertain, with the Welsh word Llif as the most plausible relative and this etymology is supported by its similarity to that of the archaic Welsh name for Liverpool Llynlleifiad. Other origins of the name have suggested, including elverpool. The name appeared in 1190 as Liuerpul, and it may be that the place appearing as Leyrpole, in a record of 1418. King Johns letters patent of 1207 announced the foundation of the borough of Liverpool, the original street plan of Liverpool is said to have been designed by King John near the same time it was granted a royal charter, making it a borough. The original seven streets were laid out in an H shape, Bank Street, Castle Street, Chapel Street, Dale Street, Juggler Street, Moor Street, in the 17th century there was slow progress in trade and population growth. Battles for the town were waged during the English Civil War, in 1699 Liverpool was made a parish by Act of Parliament, that same year its first slave ship, Liverpool Merchant, set sail for Africa. Since Roman times, the city of Chester on the River Dee had been the regions principal port on the Irish Sea

Merseyside
–
Merseyside is a metropolitan county in North West England, with a population of 1.38 million. Merseyside, which was created on 1 April 1974 as a result of the Local Government Act 1972, Merseyside spans 249 square miles of land which border Lancashire, Greater Manchester, Cheshire and the Irish Sea to the west. North Wales is across the Dee Estuary, there is a mix of high density urban areas, suburbs, semi-rural and rural locations in Merseyside, but overwhelmingly the land use is urban. For the 12 years following 1974 the county had a system of local government. The county council was abolished in 1986, and so its districts are now effectively unitary authority areas, Merseyside is joined by the neighbouring borough of Halton to form the Liverpool City Region, which together forms a local enterprise partnership and combined authority area. Further areas, including Widnes and Runcorn, were added to the Special Review Area by Order in 1965, draft proposals were published in 1965, but the commission never completed its final proposals as it was abolished in 1966. This would have included four districts, Southport/Crosby, Liverpool/Bootle, St. Helens/Widnes, in 1970 the Merseyside Passenger Transport Executive was set up, covering Liverpool, Sefton, Wirral and Knowsley, but excluding Southport and St. Helens. The Redcliffe-Maud Report was rejected by the incoming Conservative Party government, a White Paper was published in 1971. The Local Government Bill presented to Parliament involved a substantial trimming from the White Paper, excluding the northern and southern fringes of the area, excluding Chester, following the creation of Merseyside, Merseytravel expanded to take in St Helens and Southport. Between 1974 and 1986 the county had a system of local government with the five boroughs sharing power with the Merseyside County Council. However, in 1986 the government of Margaret Thatcher abolished the county council along with all other county councils. The eastern part of Merseyside borders onto Lancashire to the north, Greater Manchester to the east, the territory comprising the county of Merseyside previously formed part of the administrative counties of Lancashire and Cheshire. The two parts are linked by the two Mersey Tunnels, the Wirral Line of Merseyrail, and the Mersey Ferry, to express location within the Merseyside area by the preposition on – thus on Merseyside as opposed to in Merseyside – was traditionally the more usual. Therefore, more recent usage tends to draw distinctions between the geographical Merseyside – for which on is considered appropriate – and the Metropolitan county of Merseyside, Merseyside contains the metropolitan boroughs of Liverpool, Knowsley, Sefton, St. Helens and Wirral. This is a chart of trend of gross value added of Merseyside at current basic prices published by Office for National Statistics with figures in millions of British Pounds Sterling. This also has a usage by some local authorities and organisations and is used by Geographers A-Z Map Company for their Merseyside Street Atlas. However, a separate City region, comprising Merseyside and Halton, has official recognition as being Greater Merseyside. Halton also forms part of the Merseyside NUTS region, List of Lord Lieutenants of Merseyside List of High Sheriffs of Merseyside 1911 Liverpool general transport strike List of Sites of Special Scientific Interest in Merseyside Dickinson, Joseph

Cheshire West and Chester
–
Cheshire West and Chester is a non-metropolitan district and unitary authority with borough status in the ceremonial county of Cheshire. It was established on 1 April 2009 as part of the 2009 structural changes to government in England, by virtue of an order under the Local Government. The remainder of ceremonial Cheshire is composed of Cheshire East, Halton and Warrington, Chester City Council had proposed the new authority be called The City of Chester and West Cheshire but this was also rejected. In line with other district in Cheshire, the cabinet is composed of a leader. From its establishment in 2009, Cheshire West and Chester was governed by the Conservative Party, currently, as of 2015, the borough is governed by the Labour Party, with Samantha Dixon becoming the first female leader of the council upon taking office. The leader presently oversees a cabinet of eight, with each holding a specific portfolio. Opposition parties can also elect to appoint shadow cabinet members, though they have no executive power, all councillors vote to appoint a chairman for the following municipal year at the council AGM. Traditionally, this role was combined with that of the apolitical and ceremonial Lord Mayor of Chester, but in 2015 these roles were separated and the role of chairman was politicised. The cabinet is scrutinised by one general committee and four district committees made up of councillors, also upon establishment in 2009, Cheshire West and Chester Council inherited a number of buildings from the local authorities it replaced in every town in the borough. However, despite Cheshire County Council vacating its headquarters, the new authority spent £21 million of money purchasing and furbishing a new headquarters at HQ. County hall was sold to the University of Chester, who now use it as a campus. Meetings often take place at Chester Town Hall but also are held at Wyvern House in Winsford. There were twenty-four wards in total, meaning that seventy-two councillors were elected, the ward boundaries were also comprehensively re-drawn, with their number being increased by twenty-two to forty-six. The new wards were mostly single-member wards, with two and three-member wards for the populous areas. The 2015 election took place on 7 May, producing the first change of executive in the councils history, the borough is divided into forty-six wards, listed below in alphabetical order. The remaining length of their mandate is unclear after the United Kingdom voted to leave the European Union in the referendum held in June 2016. In line with nearly every local government district in England and Wales, the exact figure -97. 5% - is comparable with metropolitan counties such as Merseyside, non-metropolitan counties such as Cumbria and principal areas throughout Wales. This would suggest that the figure is not a significant outlier nationwide, the majority of the population of Cheshire West and Chester is British-born, with the percentage standing at 95. 1%, a figure significantly above that of the UK as a whole

Slogan
–
The Oxford Dictionary of English defines a slogan as a short and striking or memorable phrase used in advertising. A slogan usually has the attributes of being memorable, very concise and these attributes are necessary in a slogan, as it is only a short phrase. Therefore, it is necessary for slogans to be memorable, as well as concise in what the organisation or brand is trying to say, the word slogan is derived from slogorn which was an Anglicisation of the Scottish Gaelic and Irish sluagh-ghairm. Slogans vary from the written and the visual to the chanted and their simple rhetorical nature usually 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. Shankels 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 extremely valuable corporate asset, and can make up a lot of a businesss total value. With this in mind, if we take into consideration Kellers research and these include, name, logo and slogan. Brands names and logos both can be changed by the way the receiver interprets them, therefore, the slogan has a large job in portraying the brand. Therefore, the slogan should create a sense of likability in order for the name to be likable. Dass, Kumar, Kohli, & Thomas research suggests 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 product or service it is portraying. The creativity of a slogan is another factor that had an effect on the likability of a slogan. Lastly, leaving the name out of the slogan will have a positive effect on the likability of the brand itself. The original usage refers to the usage as a clan motto among Highland clans, marketing slogans are often called taglines in the United States or straplines in the United Kingdom. Europeans use the terms baselines, signatures, claims or pay-offs, sloganeering is a mostly derogatory term for activity which degrades discourse to the level of slogans. Slogans are used to convey a message about the product, service or cause that it is representing and it can have a musical tone to it or written as a song. Slogans are often used to capture the attention of the audience it is trying to reach, if the slogan is used for commercial purposes, often 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 aspect that helps create an image for the product

Frequency
–
Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as frequency, which emphasizes the contrast to spatial frequency. The period is the duration of time of one cycle in a repeating event, for example, if a newborn babys 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 vibrations, audio signals, radio waves. For cyclical processes, such as rotation, oscillations, or waves, in physics and engineering disciplines, such as optics, acoustics, and radio, frequency is usually denoted by a Latin letter f or by the Greek letter ν or ν. For a simple motion, the relation between the frequency and the period T is given by f =1 T. The SI unit of frequency is the hertz, named after the German physicist Heinrich Hertz, 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. As a matter of convenience, longer and slower waves, such as ocean surface waves, short and fast waves, like audio and radio, are usually described by their frequency instead of period. Spatial frequency is analogous to temporal frequency, but the axis is replaced by one or more spatial displacement axes. Y = sin = sin d θ d x = k Wavenumber, in the case of more than one spatial dimension, wavenumber is a vector quantity. For periodic waves in nondispersive media, frequency has a relationship to the wavelength. Even in dispersive media, the frequency f of a wave is equal to the phase velocity v of the wave divided by the wavelength λ of the wave. In the special case of electromagnetic waves moving through a vacuum, then v = c, where c is the speed of light in a vacuum, and this expression becomes, f = c λ. When waves from a monochrome source travel from one medium to another, their remains the same—only their wavelength. For example, if 71 events occur within 15 seconds the frequency is, 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 error in the calculated frequency of Δf = 1/, or a fractional error of Δf / f = 1/ where Tm is the timing interval. This error decreases with frequency, so it is a problem at low frequencies where the number of counts N is small, an older method of measuring the frequency of rotating or vibrating objects is to use a stroboscope

FM broadcasting
–
FM broadcasting is a method of radio broadcasting using frequency modulation technology. Invented in 1933 by American engineer Edwin Armstrong, it is used worldwide to provide high-fidelity sound over broadcast radio, FM broadcasting is capable of better sound quality than AM broadcasting, the chief competing radio broadcasting technology, so it is used for most music broadcasts. FM radio stations use the VHF frequencies, the term FM band describes the frequency band in a given country which is dedicated to FM broadcasting. Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion thereof, with few exceptions, In the former Soviet republics, and some former Eastern Bloc countries, assigned frequencies are at intervals of 30 kHz. This band, sometimes referred to as the OIRT band, is slowly being phased out in many countries, in those countries the 87. 5–108.0 MHz band is referred to as the CCIR band. In Japan, the band 76–95 MHz is used, the frequency of an FM broadcast station is usually an exact multiple of 100 kHz. In most of South Korea, the Americas, the Philippines, in some parts of Europe, Greenland and Africa, only even multiples are used. In the UK odd or even are used, in Italy, multiples of 50 kHz are used. There are other unusual and obsolete FM broadcasting standards in countries, including 1,10,30,74,500. Random noise has a triangular spectral distribution in an FM system and this can be offset, to a limited extent, by boosting the high frequencies before transmission and reducing them by a corresponding amount in the receiver. Reducing the high frequencies in the receiver also reduces the high-frequency noise. These processes of boosting and then reducing certain frequencies are known as pre-emphasis and de-emphasis, the amount of pre-emphasis and de-emphasis used is defined by the time constant of a simple RC filter circuit. In most of the world a 50 µs time constant is used, in the Americas and South Korea,75 µs is used. This applies to both mono and stereo transmissions, for stereo, pre-emphasis is applied to the left and right channels before multiplexing. They cannot be pre-emphasized as much because it would cause excessive deviation of the FM carrier, systems more modern than FM broadcasting tend to use either programme-dependent variable pre-emphasis, e. g. dbx in the BTSC TV sound system, or none at all. Long before FM stereo transmission was considered, FM multiplexing of other types of audio level information was experimented with. Edwin Armstrong who invented FM was the first to experiment with multiplexing and these original FM multiplex subcarriers were amplitude modulated

Hertz
–
The hertz is the unit of frequency in the International System of Units and is defined as one cycle per second. It is named for Heinrich Rudolf Hertz, the first person to provide proof of the existence of electromagnetic waves. Hertz are commonly expressed in SI multiples kilohertz, megahertz, gigahertz, kilo means thousand, mega meaning million, giga meaning billion and tera for trillion. Some of the units most common uses are in the description of waves and musical tones, particularly those used in radio-. It is also used to describe the speeds at which computers, the hertz is equivalent to cycles per second, i. e. 1/second or s −1. In English, hertz is also used as the plural form, as an SI unit, Hz can be prefixed, commonly used multiples are kHz, MHz, GHz and THz. One hertz simply means one cycle per second,100 Hz means one hundred cycles per second, and so on. The unit may be applied to any periodic event—for example, a clock might be said to tick at 1 Hz, the rate of aperiodic or stochastic events occur is expressed in reciprocal second or inverse second in general or, the specific case of radioactive decay, becquerels. Whereas 1 Hz is 1 cycle per second,1 Bq is 1 aperiodic radionuclide event per second, the conversion between a frequency f measured in hertz and an angular velocity ω measured in radians per second is ω =2 π f and f = ω2 π. This SI unit is named after Heinrich Hertz, as with every International System of Units unit named for a person, the first letter of its symbol is upper case. Note that degree Celsius conforms to this rule because the d is lowercase. — Based on The International System of Units, the hertz is named after the German physicist Heinrich Hertz, who made important scientific contributions to the study of electromagnetism. The name was established by the International Electrotechnical Commission in 1930, the term cycles per second was largely replaced by hertz by the 1970s. One hobby magazine, Electronics Illustrated, declared their intention to stick with the traditional kc. Mc. etc. units, sound is a traveling longitudinal wave which is an oscillation of pressure. Humans perceive frequency of waves as pitch. Each musical note corresponds to a frequency which can be measured in hertz. An infants ear is able to perceive frequencies ranging from 20 Hz to 20,000 Hz, the range of ultrasound, infrasound and other physical vibrations such as molecular and atomic vibrations extends from a few femtoHz into the terahertz range and beyond. Electromagnetic radiation is described by its frequency—the number of oscillations of the perpendicular electric and magnetic fields per second—expressed in hertz. Radio frequency radiation is measured in kilohertz, megahertz, or gigahertz
