Toyota A Engine
The Toyota A Series engines are a family of inline-four internal combustion engines with displacement from 1.3 L to 1.8 L produced by Toyota Motor Corporation. The series has cast iron engine blocks and aluminum cylinder heads. To make the engine as short as possible, the cylinders are siamesed. The development of the series began in the late 1970s, when Toyota wanted to develop a completely new engine for the Toyota Tercel, the successor of Toyota's K engine. The goal was to achieve good fuel efficiency and performance as well as low emissions with a modern design. The A-series includes one of the first Japanese mass-production DOHC, four-valve-per-cylinder engines, the 4A-GE, and a later version of the same engine was one of the first production five-valve-per-cylinder engines. Toyota joint venture partner Tianjin FAW Xiali produces the 1.3 L 8A and resumed production of the 5A in 2007. 1A The 1.5 L 1A was produced between 1978 an ...

4A Centre For Contemporary Asian Art
4A Centre for Contemporary Asian Art, formerly known as Gallery 4A, 4A Galleries, Asia-Australia Arts Centre and also known simply as 4A, is an Australian independent not-for-profit organisation based in the Haymarket area of Sydney, New South Wales. It commissions, exhibits, documents and researches Asian and Asian-Australian contemporary art in Australia, and promotes Australian talent in Asia, promoting and maintaining cultural connections between the nation and the region. The gallery and the associated Performance 4A (for the performing arts) were founded by the Asian Australian Artists Association Inc. in 1997. The centre is funded mainly by Commonwealth, state and local government sources, but also by private sponsors and organisations, and generates its own income. It has partnered with the Sydney Biennale twice, as well as other organisations such as the Campbelltown Arts Centre to mount major exhibitions and events. History 4A began in 1995 when a group of artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TI-99/4A
The TI-99/4 and TI-99/4A are home computers released by Texas Instruments in 1979 and 1981, respectively. Based on the Texas Instruments TMS9900 microprocessor originally used in minicomputers, the TI-99/4 was the first 16-bit home computer. The associated video display controller provides color graphics and sprite support which were only comparable with those of the Atari 400 and 800 released a month after the TI-99/4. The calculator-style keyboard of the TI-99/4 was cited as a weak point, and TI's reliance on ROM cartridges and their practice of limiting developer information to select third parties resulted in a lack of software for the system. The TI-99/4A was released in June 1981 to address some of these issues with a simplified internal design, full-travel keyboard, improved graphics, and a unique expansion system. At half the price of the original model, sales picked up significantly and TI supported the 4A with peripherals, including a speech synthesizer and a "Per ...

4A Engine
The 4A Engine is a graphics middleware engine developed by 4A Games for use in their video game ''Metro 2033'', published by THQ. It supports Direct3D APIs 9, 10, 11, and recently 12, OpenGL 3.2, along with NVidia's PhysX, and also NVidia's 3D Vision. Development The engine was developed in Ukraine by a set of people who split off from GSC Game World a year before the release of '' S.T.A.L.K.E.R.: Shadow of Chernobyl'', notably Oles Shishkovtsov and Oleksandr Maksimchuk, the programmers who worked on the development of the X-Ray engine used in the ''S.T.A.L.K.E.R.'' video game series. The engine itself is capable of running on PC, the Xbox 360, and the PlayStation 3. Shishkovtsov and his colleagues split from the development of ''S.T.A.L.K.E.R'' because that "its inherent inability to be multi-threaded, the weak and error-prone networking model, and simply awful resource and memory management which prohibited any kind of streaming or simply keeping the working set small enough ...

4A Games
4A Games Limited is a Ukrainian-Maltese video game developer based in Sliema, Malta. The company was founded in Kyiv, Ukraine, in 2006 by three developers who departed from GSC Game World. In 2014, 4A Games moved its headquarters to Sliema, wherein the Kyiv office was retained as a sub-studio. The company is best known for developing the '' Metro'' video game series. History Foundation 4A Games was founded by former developers from GSC Game World: Andrew Prokhorov, Oles Shyshkovtsov, and Alexander Maximchuk; they, together with Sergei Karmalsky, formed the core team of '' S.T.A.L.K.E.R.: Shadow of Chernobyl'', which was in development at GSC in the early and mid-2000s. Prokhorov had disliked that Sergiy Grygorovych, the chief executive officer (CEO) of GSC, prioritized money over his employees, withholding royalties for games the company had produced. The situation came to a high point when the two fell out over wages in 2006, leading Prokhorov and two of the company's le ...

4A/OP
4A/OP or, Automatized Atmospheric Absorption Atlas, is an operational fast and accurate radiative transfer model for the infrared. 4A/OP is a user-friendly software for various scientific applications (surface, balloon or space-based observations), co-developed by LMD ( Laboratoire de Meteorologie Dynamique) and NOVELTIS with the support of CNES (the French Space Agency). NOVELTIS is in charge of the industrialization and the distribution of the LMD 4A radiative transfer model. 4A allows fast and accurate computation of transmittance and radiance, owing to the use of a comprehensive database (atlases) of monochromatic optical thicknesses for up to 43 atmospheric molecular species. Precomputed once and for all, the atlases are created by using the line-by-line and layer-by-layer model, STRANSAC, with up to date physics. Owing to the computation of Jacobians (partial derivatives of the radiance with respect to atmospheric variables), the 4A model can be easily coupled with an inver ...

Long March 4A
The Long March 4A (), also known as the Changzheng 4A, CZ-4A and LM-4A, sometimes misidentified as the Long March 4 due to the lack of any such designated rocket, was a Chinese orbital carrier rocket. It was launched from Launch Area 7 at the Taiyuan Satellite Launch Center. It was a three-stage rocket, used for two launches in 1988 and 1990. On its maiden flight, on 6 September 1988, it placed the FY-1A weather satellite A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting (covering the entire Earth asynchronously), or ... into orbit. On its second, and final, flight it launched another weather satellite, FY-1B. It was replaced by a derivative, the Long March 4B, which first flew in 1999. The Long March 4B offers a more powerful third stage, and a larger payload fairing.
