8K Resolution
8K resolution refers to an image or display resolution with a width of approximately 8,000 pixels. 8K UHD () is the highest resolution defined in the Rec. 2020 (UHDTV) standard. 8K display resolution is the successor to 4K resolution. TV manufacturers pushed to make 4K a new standard by 2017. At CES 2019, the first 8K TVs were unveiled. The feasibility of a fast transition to this new standard is questionable in view of the absence of broadcasting resources. It is predicted (2018 forecast by Strategy Analytics) that 8K-ready devices will still only account for 3% of UHD TVs by 2023 with global sales of 11 million units a year. However, TV manufacturers remain optimistic as the 4K market grew much faster than expected, with actual sales exceeding projections nearly six-fold in 2016. In 2013, a transmission network's capability to carry HDTV resolution was limited by internet speeds and relied on satellite broadcast to transmit the high data rates. The demand is expected to dri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
8K UHDTV
Ultra-high-definition television (also known as Ultra HD television, Ultra HD, UHDTV, UHD and Super Hi-Vision) today includes 4K UHD and 8K UHD, which are two digital video formats with an aspect ratio of 16:9. These were first proposed by NHK Science & Technology Research Laboratories and later defined and approved by the International Telecommunication Union (ITU). The Consumer Electronics Association announced on October 17, 2012, that "Ultra High Definition", or "Ultra HD", would be used for displays that have an aspect ratio of 16:9 or wider and at least one digital input capable of carrying and presenting native video at a minimum resolution of . In 2015, the Ultra HD Forum was created to bring together the end-to-end video production ecosystem to ensure interoperability and produce industry guidelines so that adoption of ultra-high-definition television could accelerate. From just 30 in Q3 2015, the forum published a list up to 55 commercial services available around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kelvin
The kelvin, symbol K, is the primary unit of temperature in the International System of Units (SI), used alongside its prefixed forms and the degree Celsius. It is named after the Belfast-born and University of Glasgow-based engineer and physicist William Thomson, 1st Baron Kelvin (1824–1907). The Kelvin scale is an absolute thermodynamic temperature scale, meaning it uses absolute zero as its null (zero) point. Historically, the Kelvin scale was developed by shifting the starting point of the much-older Celsius scale down from the melting point of water to absolute zero, and its increments still closely approximate the historic definition of a degree Celsius, but since 2019 the scale has been defined by fixing the Boltzmann constant to be exactly . Hence, one kelvin is equal to a change in the thermodynamic temperature that results in a change of thermal energy by . The temperature in degree Celsius is now defined as the temperature in kelvins minus 273.15, meaning t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
8000 (number)
8000 (eight thousand) is the natural number following 7999 and preceding 8001. 8000 is the cube of 20, as well as the sum of four consecutive integers cubed, 113 + 123 + 133 + 143. The fourteen tallest mountains on Earth, which exceed 8000 meters in height, are sometimes referred to as eight-thousanders.

Form 8-K
Form 8-K is a very broad form used to notify investors in United States public companies of specified events that may be important to shareholders or the United States Securities and Exchange Commission. This is one of the most common types of forms filed with the SEC. After a significant event like bankruptcy or departure of a CEO, a public company generally must file a Current Report on Form 8-K within four business days to provide an update to previously filed quarterly reports on Form 10-Q and/or Annual Reports on Form 10-K. Form 8-K is required to be filed by public companies with the SEC pursuant to the Securities Exchange Act of 1934, as amended. When Form 8-K is required Form 8-K is used to notify investors of a current event. These types of events include: * signing, amending or terminating material definitive agreements not made in the ordinary course of business, bankruptcies or receiverships * mine shutdowns or violations of mine health and safety laws * consummat ...

Metres
The metre (British spelling) or meter (American spelling; see spelling differences) (from the French unit , from the Greek noun , "measure"), symbol m, is the primary unit of length in the International System of Units (SI), though its prefixed forms are also used relatively frequently. The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). In 1960, the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. The current definition was adopted in 1983 and modified slightly in 2002 to clarify that the metre is a measure of proper length. From 1983 until 2019, the metre was formally defined as the length of the path travelled by light in a vacuum in of a second. After the 2019 redefinit ...

Eight-thousander
The International Mountaineering and Climbing Federation (UIAA) recognises eight-thousanders as the 14 mountains that are more than in height above sea level, and are considered to be sufficiently independent of neighbouring peaks. There is no precise definition of the criteria used to assess independence, and, since 2012, the UIAA has been involved in a process to consider whether the list should be expanded to 20 mountains. All eight-thousanders are located in the Himalayan and Karakoram mountain ranges in Asia, and their summits are in the death zone. From 1950 to 1964, all 14 eight-thousanders were summited in the summer (the first was Annapurna I in 1950, and the last was Shishapangma in 1964), and from 1980 to 2021, all 14 were summited in the winter (the first being Mount Everest in 1980, and the last being K2 in 2021). On a variety of statistical techniques, the deadliest eight-thousander is consistently Annapurna I (one death – climber or climber support – for e ...

GCR Class 8K
The Great Central Railway (GCR) Class 8K 2-8-0 is a class of steam locomotive designed for heavy freight. Introduced in 1911, and designed by John G. Robinson, 126 were built for the GCR prior to the First World War. Including wartime construction for the British Army ROD and the post-war GCR Class 8M, the class and its derivatives totalled 666 locomotives. Great Central Railway The first of the 8K class was outshopped from the GCR's Gorton workshops in 1911. It was essentially a superheated version of an earlier 0-8-0, the 8A class, with the addition of a pony truck. This both supported the greater front end weight and gave a steadier ride. The 8K was introduced to anticipate the increased traffic from the GCR's vast new docks complex at Immingham in North East Lincolnshire and by June 1914 126 were in traffic. During the First World War there were experiments with oil burning 8Ks with larger bogie tenders. Post-war, a further 19 locomotives were built in 1918–21 t ...
