Queen's Counsel
In the United Kingdom and in some Commonwealth of Nations, Commonwealth countries, a King's Counsel (Post-nominal letters, post-nominal initials KC) during the reign of a king, or Queen's Counsel (post-nominal initials QC) during the reign of a queen regnant, queen, is a lawyer (usually a barrister or advocate) who is typically a senior trial lawyer. Technically appointed by the monarch of the country to be one of 'His [Her] Majesty's Counsel learned in the law', the position originated in England and Wales. Some Commonwealth countries have either abolished the position, or renamed it so as to remove monarchical connotations, for example, 'Senior counsel' or 'Senior Advocate'. Appointment as King's Counsel is an office, conferred by the Crown, that is recognised by courts. Members have the privilege of sitting within the inner Bar (law), bar of court. As members wear silk gowns of a particular design (see court dress), appointment as King's Counsel is known informally as ''rec ...

Quebec Central Railway
The Quebec Central Railway was a railway in the Canadian province of Quebec, that served the Eastern Townships region south of the St. Lawrence River. Its headquarters was in Sherbrooke. It was originally incorporated in 1869 as the Sherbrooke, Eastern Townships and Kennebec Railway, and changed its name to the Quebec Central Railway in 1875. In 1894, it built a line southward to Mégantic to connect to Canadian Pacific Railway's east-west line, the International Railway of Maine. It would eventually own around of track. In 1912, the Canadian Pacific Railway leased the Quebec Central for 99 years but continued to operate as Quebec Central Railway, including passenger service to American cities. The Quebec Central in turn leased the Massawippi Valley Railway, a short line from Lennoxville to Newport, in 1926; this allowed passenger service from Quebec City via Sherbrooke to the United States. The company operated passenger trains on several long and short routes. Its longest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quantum Chemistry
Quantum chemistry, also called molecular quantum mechanics, is a branch of physical chemistry focused on the application of quantum mechanics to chemical systems, particularly towards the quantum-mechanical calculation of electronic contributions to physical and chemical properties of Molecule, molecules, Material, materials, and solutions at the atomic level. These calculations include systematically applied approximations intended to make calculations computationally feasible while still capturing as much information about important contributions to the computed Wave function, wave functions as well as to observable properties such as structures, spectra, and thermodynamic properties. Quantum chemistry is also concerned with the computation of quantum effects on molecular dynamics and chemical kinetics. Chemists rely heavily on spectroscopy through which information regarding the Quantization (physics), quantization of energy on a molecular scale can be obtained. Common metho ...

Quantum Cascade Laser
Quantum-cascade lasers (QCLs) are semiconductor lasers that emit in the mid- to far-infrared portion of the electromagnetic spectrum and were first demonstrated by Jérôme Faist, Federico Capasso, Deborah Sivco, Carlo Sirtori, Albert Hutchinson, and Alfred Cho at Bell Laboratories in 1994. Unlike typical interband semiconductor lasers that emit electromagnetic radiation through the recombination of electron–hole pairs across the material band gap, QCLs are unipolar, and laser emission is achieved through the use of intersubband transitions in a repeated stack of semiconductor multiple quantum well heterostructures, an idea first proposed in the article "Possibility of amplification of electromagnetic waves in a semiconductor with a superlattice" by R. F. Kazarinov and R. A. Suris in 1971. Intersubband vs. interband transitions Within a bulk semiconductor crystal, electrons may occupy states in one of two continuous energy bands — the valence band, which is heavily ...

Quick Charge
Quick Charge (QC) is a proprietary battery charging protocol developed by Qualcomm, used for managing power delivered over USB, mainly by communicating to the power supply and negotiating a voltage. Quick Charge is supported by devices such as mobile phones which runs on Qualcomm SoCs, and by some chargers; both device and charger must support QC, otherwise QC charging is not attained. It charges batteries in devices faster than standard USB allows by increasing the output voltage supplied by the USB charger, while adopting techniques to prevent the battery damage caused by uncontrolled fast charging and regulating the incoming voltage internally. Usually, chargers supporting Quick Charge 2.0 and later are wall adaptors, but it is implemented on some in-car chargers, and some power banks use it to both receive and deliver charge. Quick Charge is also used by other manufacturers' proprietary rapid-charging systems. Details Quick Charge is a proprietary technology that allows ...

Quartz Composer
Quartz Composer is a node-based visual programming language provided as part of the Xcode development environment in macOS for processing and rendering graphical data. Quartz Composer uses OpenGL (including GLSL), OpenCL (only in Mac OS X Snow Leopard and later), Core Image, Core Video, JavaScript, and other technologies to create an API and a developer tool around a simple visual programming paradigm. Apple has embedded Quartz technologies deeply into the operating system. Compositions created in Quartz Composer can be played standalone in any QuickTime-aware application (although only on Mac OS X Tiger and later), as a system Screen Saver, as an iTunes Visualizer, from inside the Quartz Composer application, or can be embedded into a Cocoa or Carbon application via supplied user interface widgets. While Quartz Composer is included with the iPhone SDK, there is no way of running Quartz Compositions on iOS devices. Starting in macOS Catalina, the Quartz Composer framework h ...

Quantum Cryptography
Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. The best known example of quantum cryptography is quantum key distribution which offers an information-theoretically secure solution to the key exchange problem. The advantage of quantum cryptography lies in the fact that it allows the completion of various cryptographic tasks that are proven or conjectured to be impossible using only classical (i.e. non-quantum) communication. For example, it is impossible to copy data encoded in a quantum state. If one attempts to read the encoded data, the quantum state will be changed due to wave function collapse (no-cloning theorem). This could be used to detect eavesdropping in quantum key distribution (QKD). History In the early 1970s, Stephen Wiesner, then at Columbia University in New York, introduced the concept of quantum conjugate coding. His seminal paper titled "Conjugate Coding" was rejected by the IEEE Information T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quantum Computing
Quantum computing is a type of computation whose operations can harness the phenomena of quantum mechanics, such as superposition, interference, and entanglement. Devices that perform quantum computations are known as quantum computers. Though current quantum computers may be too small to outperform usual (classical) computers for practical applications, larger realizations are believed to be capable of solving certain computational problems, such as integer factorization (which underlies RSA encryption), substantially faster than classical computers. The study of quantum computing is a subfield of quantum information science. There are several models of quantum computation with the most widely used being quantum circuits. Other models include the quantum Turing machine, quantum annealing, and adiabatic quantum computation. Most models are based on the quantum bit, or "qubit", which is somewhat analogous to the bit in classical computation. A qubit can be in a 1 or 0 quantum s ...

QuakeC
QuakeC is a compiled language developed in 1996 by John Carmack of id Software to program parts of the video game '' Quake''. Using QuakeC, a programmer is able to customize ''Quake'' to great extents by adding weapons, changing game logic and physics, and programming complex scenarios. It can be used to control many aspects of the game itself, such as parts of the AI, triggers, or changes in the level. The ''Quake'' engine was the only game engine to use QuakeC. Following engines used DLL game modules for customization written in C, and C++ from id Tech 4 on. Overview The QuakeC source to the original id Software ''Quake'' game logic was published in 1996 and used as the basis for modifications like capture the flag and others. QuakeC source code is compiled using a tool called qcc into a bytecode kept in a file called . The programmers of ''Quake'' modifications could then publish their bytecode without revealing their source code. Most ''Quake'' mods were published thi ...
