XDR (audio)
XDR (expanded dynamic range), also known as SDR (super dynamic range) is a quality-control and duplication process for the mass-production of pre-recorded audio cassettes. It is a process designed to provide higher quality audio on pre-recorded cassettes by checking the sound quality at all stages of the tape duplication process. In this way, the dynamic range of audio recorded on an XDR-duplicated cassette can be up to 13 decibels greater. History XDR (Expanded Dynamic Range) was originally developed by Capitol Records in LA in their R&D facility. Before they had released anything Capitol Records-EMI of Canada was made aware of this activity and was able to release their own version called SDR (Super Dynamic Range) ahead of the American version. Capitol Records Canada was able to do this for the following reasons: :-Back in the early 80's Capitol Records Canada functioned separately from the US counterparts. :-Capitol Records Canada involved a three person team to bring this ...

XDR (video Game)
(short for "X-Dazedly-Ray") is a horizontally scrolling shooter released in Japan in 1990 for the Mega Drive. It contains six levels. Plot On the terrestrial planet Sephiroth, which is home to a variety of peaceful and prosperous advanced societies, an ancient evil has returned. A long time ago, a warmonger known only as Guardia was banished from the planet, but has finally returned with an entire space military. The Guardia Military soon invades Sephiroth and crushes its defenses with its long hardened space technology. Within time, a space fighter was developed to match the power of the Guardia Military. Based on Guardia's unknown desire for destruction and its own might, the ship was named the "XDR", or "X-Dazedly-Ray". Gameplay Players pilot the titular ship through six different checkpoint-heavy levels, blasting various ground and sky forces. Rather than having Bomb weapons, the ship is equipped to fire a variety of different shots and smaller bombs. Players can collect ...

XDR DRAM
XDR DRAM (extreme data rate dynamic random-access memory) is a high-performance dynamic random-access memory interface. It is based on and succeeds RDRAM. Competing technologies include DDR2 SDRAM, DDR2 and GDDR4 SDRAM, GDDR4. Overview XDR was designed to be effective in small, high-bandwidth consumer systems, high-performance memory applications, and high-end Graphics processing unit, GPUs. It eliminates the unusually high latency problems that plagued early forms of RDRAM. Also, XDR DRAM has heavy emphasis on per-pin bandwidth, which can benefit further cost control on PCB production. This is because fewer lanes are needed for the same amount of bandwidth. Rambus owns the rights to the technology. XDR is used by Sony in the PlayStation 3 console. Technical specifications Performance * Initial clock rate at 400 MHz. * (ODR): Eight bits per clock cycle per lane. * Each chip provides 8, 16, or 32 programmable lanes, providing up to 230.4 gigabit, Gbit/s (28.8&nbs ...

XDR Schema
XML-Data Reduced (XDR) is a discontinued schema language for specifying and validating XML documents. In January 1998, Microsoft, the University of Edinburgh and others submitted a proposal for an XML schema language called XML-Data to the World Wide Web Consortium. XML-Data Reduced was a subset of XML-Data, with some corrections and amendments submitted in July 1998. The XML Schema effort in the World Wide Web Consortium (W3C) received several other proposals, and while the final result has some similarities to the XML-Data proposal, it is significantly different. XDR was implemented in SQL Server 2000 and BizTalk Server 2000. Once the XML Schema Definition was finalized in 2001, Microsoft products and tools added support for it, and XDR was gradually phased out. Microsoft XML Core Services provided XDR schema support from versions 2.0 up to—but not including—version 6.0. See also *XML Schema Language Comparison - Comparison of other XML Schema languages (not XDR). *List ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
External Data Representation
External Data Representation (XDR) is a standard data serialization format, for uses such as computer network protocols. It allows data to be transferred between different kinds of computer systems. Converting from the local representation to XDR is called ''encoding''. Converting from XDR to the local representation is called ''decoding''. XDR is implemented as a software library of functions which is portable between different operating systems and is also independent of the transport layer. XDR uses a base unit of 4 bytes, serialized in big-endian order; smaller data types still occupy four bytes each after encoding. Variable-length types such as string and opaque are padded to a total divisible by four bytes. Floating-point numbers are represented in IEEE 754 format. History XDR was developed in the mid 1980s at Sun Microsystems, and first widely published in 1987. XDR became an IETF standard in 1995. The XDR data format is in use by many systems, including: * Network File ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multiple Drug Resistance
Multiple drug resistance (MDR), multidrug resistance or multiresistance is antimicrobial resistance shown by a species of microorganism to at least one antimicrobial drug in three or more antimicrobial categories. Antimicrobial categories are classifications of antimicrobial agents based on their mode of action and specific to target organisms. The MDR types most threatening to public health are MDR bacteria that resist multiple antibiotics; other types include MDR viruses, parasites (resistant to multiple antifungal, antiviral, and antiparasitic drugs of a wide chemical variety). Recognizing different degrees of MDR in bacteria, the terms extensively drug-resistant (XDR) and pandrug-resistant (PDR) have been introduced. Extensively drug-resistant (XDR) is the non-susceptibility of one bacteria species to all antimicrobial agents except in two or less antimicrobial categories. Within XDR, pandrug-resistant (PDR) is the non-susceptibility of bacteria to all antimicrobial agents i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Special Drawing Rights
Special drawing rights (SDRs, code ) are supplementary foreign exchange reserve assets defined and maintained by the International Monetary Fund (IMF). SDRs are units of account for the IMF, and not a currency ''per se''. They represent a claim to currency held by IMF member countries for which they may be exchanged. SDRs were created in 1969 to supplement a shortfall of preferred foreign exchange reserve assets, namely gold and U.S. dollars. The ISO 4217 currency code for special drawing rights is and the numeric code is ''960''. SDRs are allocated by the IMF to countries, and cannot be held or used by private parties. The number of SDRs in existence was around XDR 21.4 billion in August 2009. During the global financial crisis of 2009, an additional XDR 182.6 billion was allocated to "provide liquidity to the global economic system and supplement member countries' official reserves". By October 2014, the number of SDRs in existence was XDR 204 bil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
