It is classified among "R1: Doctoral Universities – Very high research activity". VT has produce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intel VT-c
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. In software-based virtualization, a host OS has direct access to hardware while the guest OSs have limited ... [...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 reintrodu ...

VT Group
VT Group is a privately held United States defense and services company, with its origins in a former British shipbuilding group, previously known as Vosper Thornycroft. The British part of VT Group was integrated into Babcock International in the early 2010s. In July 2012, The Resolute Fund II, LP, an affiliate of The Jordan Company acquired VT Group. History VT Group plc was a British defense and services company, formerly known as Vosper Thornycroft. The company had diversified from shipbuilding into various engineering and support services, becoming involved in many areas of provision through five main operating groups: VT Communications, VT Education and Skills, VT Services Inc and VT Support Services. VT Group exited the shipbuilding industry in October 2009, after selling its 45% share of the Shipbuilding Joint Venture company BVT Surface Fleet to BAE Systems. Formerly listed on the London Stock Exchange and a constituent of the FTSE 250 Index, the remainder of the fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virginia And Truckee Railroad
The Virginia and Truckee Railroad is a privately owned heritage railroad, headquartered in Virginia City, Nevada. Its private and publicly owned route is long. When first constructed in the 19th century, it was a commercial freight railroad which was originally built to serve the Comstock Lode mining communities of northwestern Nevada. At its height, the railroad's route ran from Reno south to the state capital at Carson City. In Carson City, the mainline split into two branches. One branch continued south to Minden, while the other branch traveled east to Virginia City. The first section from Virginia City to Carson City was constructed beginning in 1869 to haul ore, lumber and supplies for the Comstock Lode silver mines. The railroad was abandoned in 1950 after years of declining revenue. Much of the track was pulled up and sold, along with the remaining locomotives and cars. In the 1970s, with public interest in historic railroads on the rise, efforts began to rebuild th ... [...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".

Proximity Fuze
A proximity fuze (or fuse) is a fuze that detonates an 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 the target or after passing it. At th ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
