Quebec
Quebec is Canada's List of Canadian provinces and territories by area, largest province by area. Located in Central Canada, the province shares borders with the provinces of Ontario to the west, Newfoundland and Labrador to the northeast, New Brunswick to the southeast and a coastal border with the territory of Nunavut. In the south, it shares a border with the United States. Between 1534 and 1763, what is now Quebec was the List of French possessions and colonies, French colony of ''Canada (New France), Canada'' and was the most developed colony in New France. Following the Seven Years' War, ''Canada'' became a Territorial evolution of the British Empire#List of territories that were once a part of the British Empire, British colony, first as the Province of Quebec (1763–1791), Province of Quebec (1763–1791), then Lower Canada (1791–1841), and lastly part of the Province of Canada (1841–1867) as a result of the Lower Canada Rebellion.

Quartz Composer
Quartz Composer is a node graph system provided as part of the Xcode development environment in macOS for processing and rendering graphical data. It is capable of making sophisticated animations for keynote or presentations and creating animated screensavers. Quartz Composer uses OpenGL (including GLSL), OpenCL (only in Mac OS X Snow Leopard and later), OpenAL, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queen's Counsel
A King's Counsel (Post-nominal letters, post-nominal initials KC) is a senior lawyer appointed by the monarch (or their Viceroy, viceregal representative) of some Commonwealth realms as a "Counsel learned in the law". When the reigning monarch is a woman, the title is Queen's Counsel (QC). The position originated in England and Wales. Some Commonwealth countries have retained the designation, while others 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 recognised by courts. Members in the UK have the privilege of sitting within the inner Bar (law), bar of court. As members wear silk gowns of a particular design, appointment as King's Counsel is known informally as ''taking silk'' and KCs are often colloquially called ''silks''. Appointments are made from within the legal profession on the basis of merit and not a particular level of expe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Quality Control
Quality control (QC) is a process by which entities review the quality of all factors involved in production. ISO 9000 defines quality control as "a part of quality management focused on fulfilling quality requirements". This approach places emphasis on three aspects (enshrined in standards such as ISO 9001): # Elements such as controls, job management, defined and well managed processes, performance and integrity criteria, and identification of records # Competence, such as knowledge, skills, experience, and qualifications # Soft elements, such as personnel, integrity, confidence, organizational culture, motivation, team spirit, and quality relationships. Inspection is a major component of quality control, where physical product is examined visually (or the end results of a service are analyzed). Product inspectors will be provided with lists and descriptions of unacceptable product defects such as cracks or surface blemishes for example. History and introductio ...

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 heavil ...

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 Thermodynamics, 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 ...

Quick Charge
Quick Charge (QC) is a proprietary charge controller#Charging protocols, 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 run on Qualcomm system-on-chip (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 buck converter, regulating the incoming voltage internally. Many chargers supporting Quick Charge 2.0 and later are wall adaptors, but it is implemented on some automobile auxiliary power outlet, in-car chargers, and some battery charger#Power bank, power banks use it to both receive and deliver charge. Quick Charge is also us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Informa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quantum Computing
A quantum computer is a computer that exploits quantum mechanical phenomena. On small scales, physical matter exhibits properties of wave-particle duality, both particles and waves, and quantum computing takes advantage of this behavior using specialized hardware. Classical physics cannot explain the operation of these quantum devices, and a scalable quantum computer could perform some calculations Exponential growth, exponentially faster than any modern "classical" computer. Theoretically a large-scale quantum computer could post-quantum cryptography, break some widely used encryption schemes and aid physicists in performing quantum simulator, physical simulations; however, the current state of the art is largely experimental and impractical, with several obstacles to useful applications. The basic unit of information in quantum computing, the qubit (or "quantum bit"), serves the same function as the bit in classical computing. However, unlike a classical bit, which can be in ...
