Verlag Technik
(abbr. VT, formerly , which temporarily operated as ) based in Berlin today is the remaining part of its incorporation into the . History The in Berlin was a specialist book and specialist journal publisher in the former German Democratic Republic (GDR). It was founded on 1 July 1946 and was a Volkseigener Betrieb (VEB) (English, "publicly owned enterprise"). Besides the it was one of the most important publishers of specialist books in the field of technology and natural sciences in the GDR up to and including the years immediately after the in the reunified Germany, after which the number of new publications by Verlag Technik decreased significantly. During its East German years it also published many trade journals for various technical fields, e.g. (Radio television electronics), (MP microprocessor technology), (New technology in the office), (Agricultural engineering), (KFT) or (Technology - technical-scientific journal for basic and cross-sectional questions) ...

Video Toaster
The NewTek Video Toaster is a combination of hardware and software for the editing and production of NTSC standard-definition video. The plug-in expansion card initially worked with the Amiga 2000 computer and provides a number of BNC connectors on the exposed rear edge that provide connectivity to common analog video sources like VHS VCRs. The related software tools support video switching, chroma keying, character generation, animation, and image manipulation. Together, the hardware and software provided, for a few thousand U.S. dollars, a video editing suite that rivaled the output of contemporary (i.e. early 1990s) professional systems costing ten times as much. It allowed small studios to produce high-quality material and resulted in a cottage industry for video production not unlike the success of the Macintosh in the desktop publishing ( DTP) market only a few years earlier. The Video Toaster won the Emmy Award for Technical Achievement in 1993. Other parts of the origi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Training
Educational technology (commonly abbreviated as edutech, or edtech) is the combined use of computer hardware, software, and educational theory and practice to facilitate learning. When referred to with its abbreviation, edtech, it often refers to the industry of companies that create educational technology. In addition to the practical educational experience, educational technology is based on theoretical knowledge from various disciplines such as communication, education, psychology, sociology, artificial intelligence, and computer science. It encompasses several domains including learning theory, computer-based training, online learning, and m-learning where mobile technologies are used. Definition The Association for Educational Communications and Technology (AECT) has defined educational technology as "the study and ethical practice of facilitating learning and improving performance by creating, using and managing appropriate technological processes and resources".

Videotape
Videotape is magnetic tape used for storing video and usually sound in addition. Information stored can be in the form of either an analog or digital signal. Videotape is used in both video tape recorders (VTRs) and, more commonly, videocassette recorders (VCRs) and camcorders. Videotapes have also been used for storing scientific or medical data, such as the data produced by an electrocardiogram. Because video signals have a very high bandwidth, and stationary heads would require extremely high tape speeds, in most cases, a helical-scan video head rotates against the moving tape to record the data in two dimensions. Tape is a linear method of storing information and thus imposes delays to access a portion of the tape that is not already against the heads. The early 2000s saw the introduction and rise to prominence of high-quality random-access video recording media such as hard disks and flash memory. Since then, videotape has been increasingly relegated to archival and si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proximity Fuze
A proximity fuze (or fuse) is a Fuze (munitions), fuze that detonates an Explosive material, explosive device automatically when the distance to the target becomes smaller than a predetermined value. Proximity fuzes are designed for targets such as planes, missiles, ships at sea, and ground forces. They provide a more sophisticated trigger mechanism than the common contact fuze or timed fuze. It is estimated that it increases the lethality by 5 to 10 times, compared to these other fuzes. Background Before the invention of the proximity fuze, detonation was induced by direct contact, a timer set at launch or an altimeter. All of these earlier methods have disadvantages. The probability of a direct hit on a small moving target is low; a shell that just misses the target will not explode. A time- or height-triggered fuze requires good prediction by the gunner and accurate timing by the fuze. If either is wrong, then even accurately aimed shells may explode harmlessly before reaching ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holden Commodore (VT)
The Holden Commodore (VT) is an executive car that was produced by Holden from 1997 to 2000. It was the first iteration of the third generation of the Commodore and the last one to be powered by a locally made V8 engine (1998). Its range included the luxury variants, Holden Berlina (VT) and Holden Calais (VT) but not a new generation utility version. Introduced in August 1997, the VT-series represented Holden's largest development yet. On debut, it won the 1997 ''Wheels Car of the Year'' award, resulting in the fourth time that this award was won by a Commodore. It found ready acceptance in the market as many buyers steered away from the more radically designed Ford Falcon (AU), becoming the best selling Commodore and cementing its place as number one in Australian sales at its time. The VT Series II (VT II) was released in 1999, before being replaced by the restyled VX model in 2000. In 1998, the VT formed the basis of a prototype that became the catalyst for the reintroducti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ventricular Tachycardia
Ventricular tachycardia (V-tach or VT) is a fast heart rate arising from the lower chambers of the heart. Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm. Short periods may occur without symptoms, or present with lightheadedness, palpitations, or chest pain. Ventricular tachycardia may result in ventricular fibrillation (VF) and turn into cardiac arrest. This conversion of the VT into VF is called the degeneration of the VT. It is found initially in about 7% of people in cardiac arrest. Ventricular tachycardia can occur due to coronary heart disease, aortic stenosis, cardiomyopathy, electrolyte problems, or a heart attack. Diagnosis is by an electrocardiogram (ECG) showing a rate of greater than 120 beats per minute and at least three wide QRS complexes in a row. It is classified as non-sustained versus sustained based on whether it lasts le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vanishing Twin
A vanishing twin, also known as twin resorption, is a fetus in a multigestation pregnancy that dies ''in utero ''and is then partially or completely reabsorbed. In some instances, the dead twin is compressed into a flattened, parchment-like state known as ''fetus papyraceus''. Vanishing twins occur in up to one of every eight multifetus pregnancies and may not even be known in most cases. "High resorption rates, which cannot be explained on the basis of the expected abortion rate, suggest intense fetal competition for space, nutrition, or other factors during early gestation, with frequent loss or resorption of the other twin(s)." In pregnancies achieved by ''in vitro'' fertilization, "it frequently happens that more than one amniotic sac can be seen in early pregnancy, whereas a few weeks later there is only one to be seen and the other has 'vanished'". See also * Chimera (genetics) * Mosaicism * Parasitic twin A parasitic twin, also known as an asymmetrical or unequal c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intel VT-x
x86 virtualization is the use of hardware-assisted virtualization capabilities on an x86/x86-64 CPU. In the late 1990s x86 virtualization was achieved by complex software techniques, necessary to compensate for the processor's lack of hardware-assisted virtualization capabilities while attaining reasonable performance. In 2005 and 2006, both Intel (VT-x) and AMD ( AMD-V) introduced limited hardware virtualization support that allowed simpler virtualization software but offered very few speed benefits. Greater hardware support, which allowed substantial speed improvements, came with later processor models. Software-based virtualization The following discussion focuses only on virtualization of the x86 architecture protected mode. In protected mode the operating system kernel runs at a higher privilege such as ring 0, and applications at a lower privilege such as ring 3.
