Light Emitting Capacitor
Electroluminescence (EL) is an optical and electrical phenomenon, in which a material emits light in response to the passage of an electric current or to a strong electric field. This is distinct from black body light emission resulting from heat (incandescence), a chemical reaction (chemiluminescence), sound (sonoluminescence), or other mechanical action (mechanoluminescence). Mechanism Electroluminescence is the result of radiative recombination of electrons & holes in a material, usually a semiconductor. The excited electrons release their energy as photons - light. Prior to recombination, electrons and holes may be separated either by doping the material to form a p-n junction (in semiconductor electroluminescent devices such as light-emitting diodes) or through excitation by impact of high-energy electrons accelerated by a strong electric field (as with the phosphors in electroluminescent displays). It has been recently shown that as a solar cell improves its light-to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Edinburgh
The University of Edinburgh ( sco, University o Edinburgh, gd, Oilthigh Dhùn Èideann; abbreviated as ''Edin.'' in post-nominals) is a public research university based in Edinburgh, Scotland. Granted a royal charter by King James VI in 1582 and officially opened in 1583, it is one of Scotland's four ancient universities and the sixth-oldest university in continuous operation in the English-speaking world.

Levelised Energy Cost
The levelized cost of electricity (LCOE), or levelized cost of energy, is a measure of the average net present cost of electricity generation for a generator over its lifetime. It is used for investment planning and to compare different methods of electricity generation on a consistent basis. The LCOE "represents the average revenue per unit of electricity generated that would be required to recover the costs of building and operating a generating plant during an assumed financial life and duty cycle", and is calculated as the ratio between all the discounted costs over the lifetime of an electricity generating plant divided by a discounted sum of the actual energy amounts delivered. Inputs to LCOE are chosen by the estimator. They can include the cost of capital, decommissioning, fuel costs, fixed and variable operations and maintenance costs, financing costs, and an assumed utilization rate. Calculation The LCOE is calculated as: : \mathrm = \frac = \frac :: : Typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light-emitting Electrochemical Cell
A light-emitting electrochemical cell (LEC or LEEC) is a solid-state device that generates light from an electric current (electroluminescence). LECs are usually composed of two metal electrodes connected by (e.g. sandwiching) an organic semiconductor containing mobile ions. Aside from the mobile ions, their structure is very similar to that of an organic light-emitting diode (OLED). LECs have most of the advantages of OLEDs, as well as additional ones: * The device is less dependent on the difference in work function of the electrodes. Consequently, the electrodes can be made of the same material (e.g. gold). Similarly, the device can still be operated at low voltages. * Recently developed materials such as graphene or a blend of carbon nanotubes and polymers have been used as electrodes, eliminating the need for using indium tin oxide for a transparent electrode. * The thickness of the active electroluminescent layer is not critical for the device to operate. This means that: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LucasArts
Lucasfilm Games (known as LucasArts between 1990 and 2021) is an American video game licensor that is part of Lucasfilm. It was founded in May 1982 by George Lucas as a video game development group alongside his film company; as part of a larger 1990 reorganization of the Lucasfilm divisions, the video game development division was grouped and rebranded as part of LucasArts. LucasArts became known for its line of adventure games based on its SCUMM engine in the 1990s, including ''Maniac Mansion'', the ''Monkey Island'' series, and several ''Indiana Jones'' titles. A number of influential game developers were alumni of LucasArts from this period, including Brian Moriarty, Tim Schafer, Ron Gilbert, and Dave Grossman. Later, as Lucasfilm regained control over its licensing over the ''Star Wars'' franchise, LucasArts produced numerous action-based ''Star Wars'' titles in the late 1990s and early 2000s, while dropping adventure game development due to waning interest in the genre. ...

Line Echo Cancellation
Echo suppression and echo cancellation are methods used in telephony to improve voice quality by preventing echo from being created or removing it after it is already present. In addition to improving subjective audio quality, echo suppression increases the capacity achieved through silence suppression by preventing echo from traveling across a telecommunications network. Echo suppressors were developed in the 1950s in response to the first use of satellites for telecommunications. Echo suppression and cancellation methods are commonly called acoustic echo suppression (AES) and acoustic echo cancellation (AEC), and more rarely line echo cancellation (LEC). In some cases, these terms are more precise, as there are various types and causes of echo with unique characteristics, including acoustic echo (sounds from a loudspeaker being reflected and recorded by a microphone, which can vary substantially over time) and line echo (electrical impulses caused by, e.g., coupling between t ...

League Of Legends
''League of Legends'' (''LoL''), commonly referred to as ''League'', is a 2009 multiplayer online battle arena video game developed and published by Riot Games. Inspired by ''Defense of the Ancients'', a custom map for ''Warcraft III'', Riot's founders sought to develop a stand-alone game in the same genre. Since its release in October 2009, ''League'' has been free-to-play and is monetized through purchasable character customization. The game is available for Microsoft Windows and macOS. In the game, two teams of five players battle in player-versus-player combat, each team occupying and defending their half of the map. Each of the ten players controls a character, known as a "champion", with unique abilities and differing styles of play. During a match, champions become more powerful by collecting experience points, earning gold, and purchasing items to defeat the opposing team. In ''League''s main mode, Summoner's Rift, a team wins by pushing through to the enemy base ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
League Of Legends European Championship
The ''League of Legends'' EMEA Championship (LEC) is the professional ''League of Legends'' esports league run by Riot Games in the EMEA (Europe, the Middle East and Africa) region, in which ten teams compete. Each annual season of play is divided into two splits, spring and summer, both consisting of nine weeks of round-robin tournament play, which then conclude with play-off tournaments between the top six teams.

Lee–Enfield
The Lee–Enfield or Enfield is a bolt-action, magazine-fed repeating rifle that served as the main firearm of the military forces of the British Empire and Commonwealth during the first half of the 20th century, and was the British Army's standard rifle from its official adoption in 1895 until 1957. The WWI versions are often referred to as the "SMLE", which is short for the common "Short, Magazine, Lee–Enfield" variant. A redesign of the Lee–Metford (adopted by the British Army in 1888), the Lee–Enfield superseded the earlier Martini–Henry, Martini–Enfield, and Lee-Metford rifles. It featured a ten-round box magazine which was loaded with the .303 British cartridge manually from the top, either one round at a time or by means of five-round chargers. The Lee–Enfield was the standard issue weapon to rifle companies of the British Army, colonial armies (such as India and parts of Africa), and other Commonwealth nations in both the First and Second World Wars ( ...

Climate Change Levy
The Climate Change Levy (CCL) is a tax on energy delivered to non-domestic users in the United Kingdom. Scope and purpose Introduced on 1 April 2001 under the Finance Act 2000, it was forecast to cut annual emissions by 2.5 million tonnes by 2010, and forms part of the UK's Climate Change Programme. The levy applies to most energy users, with the notable exceptions of those in the domestic and transport sectors. Electricity from nuclear is taxed even though it causes no direct carbon emissions. Originally electricity generated from new renewables and approved cogeneration schemes was not taxed, but the July 2015 Budget removed this exemption from 1 August 2015, raising £450m/year. Rates From when it was introduced, the levy was frozen at 0.43p/kWh on electricity, 0.15p/kWh on coal and 0.15p/kWh on gas. A reduction of up to 90% from the levy may be gained by energy-intensive users provided they sign a Climate Change Agreement. Revenue from the levy was offset by a 0.3 ...
