High-voltage Differential Signaling
Differential signalling is a method for electrically transmitting information using two complementary signals. The technique sends the same electrical signal as a differential pair of signals, each in its own conductor. The pair of conductors can be wires in a twisted-pair or ribbon cable or traces on a printed circuit board. Electrically, the two conductors carry voltage signals which are equal in magnitude, but of opposite polarity. The receiving circuit responds to the difference between the two signals, which results in a signal with a magnitude twice as large. The symmetrical signals of differential signalling may be referred to as ''balanced'', but this term is more appropriately applied to balanced circuits and balanced lines which reject common-mode interference when fed into a differential receiver. Differential signalling does not make a line balanced, nor does noise rejection in balanced circuits require differential signalling. Differential signalling is to ...

Computer
A computer is a machine that can be programmed to Execution (computing), carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as Computer program, programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the Computer hardware, hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of Programmable logic controller, industrial and Consumer electronics, consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devi ...

Desktop Virtualization
Desktop virtualization is a software technology that separates the desktop environment and associated application software from the physical client device that is used to access it. Desktop virtualization can be used in conjunction with application virtualization and user profile management systems, now termed user virtualization, to provide a comprehensive desktop environment management system. In this mode, all the components of the desktop are virtualized, which allows for a highly flexible and much more secure desktop delivery model. In addition, this approach supports a more complete desktop disaster recovery strategy as all components are essentially saved in the data center and backed up through traditional redundant maintenance systems. If a user's device or hardware is lost, the restore is straightforward and simple, because the components will be present at login from another device. In addition, because no data are saved to the user's device, if that device is lost, ...

High-Definition Versatile Disc
High-Definition Versatile Disc (HVD) is an Asian standard of advanced high-definition technology originally developed in China by AMLogic Inc., for high-definition video. The format supports 720p, 1080i, or 1080p video on version 1 discs. Version 2 of the format added high-resolution beyond the standard fare of HD for use on non-TV monitors that support higher resolutions, up to 1080p. A modified MPEG-2 MP@HL video-codec is used and the format supports audio encoded in Dolby AC3, DTS, Dolby Digital EX, DTS ES, and Prologic 2 audio formats. All HVDs use standard DVD discs. While the format is referred to as HVD it has no relation to the Holographic Versatile Disc format that came along later and used the same acronym. There are only a few DVD players which support this format. Nero Showtime, Media Player Classic, PowerDVD, VLC media player, and XBMC are the few known software packages to handle the format as the MPEG2 files are non-standard. Though popular in China, the f ...

Holographic Versatile Disc
The Holographic Versatile Disc (HVD) is an optical disc technology that was expected to store up to several terabytes of data on an optical disc 10 cm or 12 cm in diameter. Its development commenced in April 2004, but it never arrived due to lack of funding. The company responsible for HVD went bankrupt in 2010. The reduced radius reduces cost and materials used. It employs a technique known as collinear holography, whereby a blue-green and red laser beam are collimated in a single beam. The blue-green laser reads data encoded as laser interference fringes from a holographic layer near the top of the disc. A red laser is used as the reference beam to read servoinformation from a regular CD-style aluminium layer near the bottom. Servoinformation is used to monitor the position of the read head over the disc, similar to the head, track, and sector information on a conventional hard disk drive. On a CD or DVD this servoinformation is interspersed among the data. A dichr ...

High-value Detention Site
A high-value detention site or HVD, in current U.S. military parlance, is a prison for those who may have valuable intelligence to offer, or who have inherent military or political significance. An example is former Iraqi president Saddam Hussein, as well as senior members of his regime. Other prisoners of these sites include members of Al-Qaeda, captured during the War on Terrorism. List of sites * Bagram prison (2001–2012) in Afghanistan * Guantánamo Bay (est. 2002) in Cuba * Abu Ghraib prison (2004–2006) in Iraq * Camp Cropper (est. 2003) near Baghdad International Airport Baghdad International Airport , previously Saddam International Airport ( ar, مطار بغداد الدولي, Maṭār Baġdād ad-Dawaliyy) is Iraq's largest international airport, located in a suburb about west of downtown Baghdad in the ..., Iraq Imprisonment and detention in the United States {{US-mil-stub ...

Humanistischer Verband Deutschlands
The Humanistischer Verband Deutschlands (English: ''Humanist Association of Germany'') is an organisation to promote and spread a secular humanist worldview and an advocate for the rights of nonreligious people. It was founded 1993 in Berlin and counts about 20,000 members. The HVD is a member of the International Humanist and Ethical Union and the European Humanist Federation. History The federation was formed in 1993, some years after the reunification of Germany at the end of a difficult period for organised humanism, which had been stamped out by the Nazis early in the lead-up to World War II, and then suppressed by communism in the East and strong religious majorities in the West of Germany. HVD's predecessor, the German Freethinkers League, was very successful at the time it was targeted by Hitler, with 500,000 members across Germany. Aims The HVD is committed to secularism, human rights, democracy, egalitarianism and mutual respect. The association works for an open and i ...
