Low frequency
Low frequency (LF) is the ITU designation for radio frequencies (RF) in the range of 30–300 kHz. Since its wavelengths range from 10–1 km, respectively, it is also known as the kilometre band or kilometre waves.

LF radio waves exhibit low signal attenuation, making them suitable for long-distance communications. In Europe and areas of Northern Africa and Asia, part of the LF spectrum is used for AM broadcasting as the "longwave" band. In the western hemisphere, its main use is for aircraft beacons, navigation (LORAN, mostly defunct), information, and weather systems. A number of time signal broadcasts also use this band. The main mode of transmission used in this band is ground waves, in which LF radio waves travel just above the Earth's surface, following the terrain. LF ground waves can travel over hills, and can travel far beyond the horizon, up to several hundred kilometers from the transmitter.

Attenuation
In physics, attenuation is the gradual loss of flux intensity through a medium. For instance, dark glasses attenuate sunlight, lead attenuates X-rays, and water and air attenuate both light and sound at variable attenuation rates.

Hearing protectors help reduce acoustic flux from flowing into the ears. This phenomenon is called acoustic attenuation and is measured in decibels (dBs).

In electrical engineering and telecommunications, attenuation affects the propagation of waves and signals in electrical circuits, in optical fibers, and in air. Electrical attenuators and optical attenuators are commonly manufactured components in this field.

Cities of Japan
A city (市, shi) is a local administrative unit in Japan. Cities are ranked on the same level as towns (町, machi) and villages (村, mura), with the difference that they are not a component of districts (郡, gun). Like other contemporary administrative units, they are defined by the Local Autonomy Law of 1947.
Rustenburg Local Municipality

Local municipality (South Africa)
In South Africa, a local municipality (Tswana: mmasepalaselegae; Sotho: masepala wa lehae; Northern Sotho: mmasepala wa selegae; Afrikaans: plaaslike munisipaliteit; Zulu: umasipala wendawo; Southern Ndebele: umasipaladi wendawo; Xhosa: umasipala wengingqi; Swazi: masipaladi wasekhaya; Venda: masipalawapo; Tsonga: masipala wa muganga) or Category B municipality is a type of municipality that serves as the third, and most local, tier of local government. Each district municipality is divided into a number of local municipalities, and responsibility for municipal affairs is divided between the district and local municipalities. There are 205 local municipalities in South Africa.

A local municipality may include rural areas as well as one or more towns or small cities. In larger urban areas there are no district or local municipalities, and a metropolitan municipality is responsible for all municipal affairs.

Hilbert basis (linear programming)
The Hilbert basis of a convex cone C is a minimal set of integer vectors in C such that every integer vector in C is a conical combination of the vectors in the Hilbert basis with integer coefficients.

Conical combination
Given a finite number of vectors  in a real vector space, a conical combination, conic combination, conical sum, or weighted sum
of these vectors is a vector of the form

where  are non-negative real numbers.

The name derives from the fact that the set of all conical sum of vectors defines a cone (possibly in a lower-dimensional subspace).
Song Jiaoren
Song Jiaoren (Chinese: 宋敎仁; pinyin: Sòng Jiàorén; Wade–Giles: Sung Chiao-jen, [sʊ̂ŋ tɕjâʊɻə̌n]; Given name at birth: Liàn 鍊; Courtesy name: Dùnchū 鈍初; 5 April 1882 – 22 March 1913) was a Chinese republican revolutionary, political leader and a founder of the Kuomintang (KMT). Song Jiaoren led the KMT to electoral victories in China's first democratic election. He based his appeal on the upper class gentry, landowners, and merchants.  Historians have concluded that provisional president Yuan Shikai was responsible for his assassination on 22 March 1913.

President of the Republic of China
The president of the Republic of China, also known as the president of Taiwan, is the head of state of the Republic of China (Taiwan), as well as the commander-in-chief of the Republic of China Armed Forces. Before 1949 the position had the authority of ruling over mainland China, but losing control of it after communist victory in the Chinese Civil War, the remaining jurisdictions of the ROC have been limited to Taiwan, Penghu, Kinmen, Matsu, and smaller islands.

Originally elected by the National Assembly, the presidency was intended to be a ceremonial office with no real executive power because the ROC was originally envisioned as a parliamentary republic. Since the 1996 election however, the president has been directly elected by plurality voting to a four-year term, with incumbents limited to serving two terms. The current president is Lai Ching-te of the Democratic Progressive Party, preceded by Tsai Ing-wen from the same party.

She was captain of the national team from its inception in 2009 to 2017, and continues to play as one of the nation's top performing athletes.

All-rounder
An all-rounder is a cricketer who regularly performs well at both batting and bowling. Although all bowlers must bat and quite a handful of batsmen do bowl occasionally, most players are skilled in only one of the two disciplines and are considered specialists. Some wicket-keepers have the skills of a specialist batter and have been referred to as all-rounders, but the term wicket-keeper-batter is more commonly applied to them, even if they are substitute wicket keepers who also bowl.

Tuti Bridge
The Tuti Bridge (Arabic: جسر توتي) is a modern suspension bridge linking between Tuti Island and the City of Khartoum in Sudan that was completed in February 2008.
In the past the only approach to Tuti Island was via ferries but thanks to the Tuti-Khartoum Bridge, easy access to the island is possible.

The bridge is considered to be the first suspension bridge to be constructed in Sudan and one of the first constructed in Africa. The concept design of the bridge was proposed by Alfatih Ahmed, with the final working design by A&A Company Its construction depended on new bridge technology, enabling the erection to be carried out using local expertise and equipment.

The Tuti-Khartoum Bridge is the first among a series of bridges that will connect the cities of Khartoum, Omdurman and Bahri (North Khartoum), and will help to alleviate traffic throughout the cities. The development has immediately commercialised the previously isolated Tuti Island.

Khartoum North
Khartoum North, or Khartoum Bahri or simply Bahri (Arabic: الخرطوم بحري, romanized: al-Kharṭūm Baḥrī), is a city in Khartoum State, lying to the north of Khartoum city, the capital of Sudan. It has a population of 1,012,211 people, making it the third-largest city proper in Sudan, behind the neighbouring cities of Omdurman and Khartoum.
History of Mexican Americans
The history of Mexican Americans largely begins the aftermath of the annexation of Northern Mexico in 1848, when nearly 80,000 Mexican citizens—of what are now California, Nevada, Utah, Arizona, Colorado, and New Mexico—became U.S. citizens. Large-scale migration increased the U.S.' Mexican population during the 1910s, as refugees fled the economic devastation and violence of Mexico's revolution and civil war. Until the mid-20th century, most Mexican Americans lived within a few hundred miles of the border, although some resettled along rail lines from the Southwest into the Midwest.

In the second half of the 20th century, Mexican Americans diffused throughout the U.S., especially into the Midwest and Southeast, though the groups' largest population centers remain in California and Texas. During this period, Mexican-Americans campaigned for voting rights, educational and employment equity, ethnic equality, and economic and social advancement.

Lower Rio Grande Valley
The Lower Rio Grande Valley (Spanish: Valle del Río Grande), often referred to as the Rio Grande Valley (RGV) of South Texas, is a region located in the southernmost part of Texas. It is located along the border of Texas with Mexico located in a floodplain of the Rio Grande near its mouth. The region includes the southernmost tip of South Texas. It consists of the Brownsville-Harlingen and McAllen-Edinburg-Mission metropolitan areas, and the Rio Grande City-Roma and Raymondville micropolitan areas. The area is generally bilingual in English and Spanish, with a fair amount of Spanglish due to the region's diverse history and transborder agglomerations. It is home to some of the poorest cities in the nation, as well as many unincorporated, persistent poverty communities called colonias. A large seasonal influx occurs of "winter Texans" – people who come down from the north for the winter and then return north before summer arrives.
Nieuwegein-Zuid (tram stop)
Nieuwegein-Zuid is a tram stop of the Utrecht sneltram network, located in the most southern part of Nieuwegein. The stop opened in 1983. Today it is the terminus of tram route 20 from Utrecht Central Station and P+R Science Park. It connects the Hoog-Zandveld neighbourhood of Nieuwegein with IJsselstein and Utrecht. It is located right next to a shopping center.

Tram stop
A tram stop, tram station, streetcar stop, or light rail station is a place designated for a tram, streetcar, or light rail vehicle to stop so passengers can board or alight it. Generally, tram stops share most characteristics of bus stops, but because trams operate on rails, they often include railway platforms, especially if stepless entries are provided for accessibility. However, trams may also be used with bus stop type flags and with mid-street pavements as platforms, in street running mode.
Everything's Alright (The Newbeats song)
"Everything's Alright" is a song written by John D. Loudermilk and performed by The Newbeats.  It reached #6 in Canada, #16 on the Billboard Hot 100, and #53 in Australia in 1964.

Kent Music Report
The Kent Music Report was a weekly record chart of Australian music singles and albums which was compiled by music historian David Kent from May 1974 through to January 1999. The chart was re-branded the Australian Music Report (AMR) in July 1987. From June 1988, the Australian Recording Industry Association, which had been using the top 50 portion of the report under licence since mid-1983, chose to produce their own listing as the ARIA Charts.

Before the Kent Report, Go-Set magazine published weekly Top 40 Singles from 1966, and albums chart from 1970 until the magazine's demise in August 1974.

David Kent later published Australian charts from 1940 to 1973 in a retrospective fashion, using state by state chart data obtained from various Australian radio stations.
