Quezon City
Quezon City (, ; fil, Lungsod Quezon ), also known as the City of Quezon and Q.C. (read in Filipino as Kyusi), is the List of cities in the Philippines, most populous city in the Philippines. According to the 2020 census, it has a population of 2,960,048 people. It was founded on October 12, 1939, and was named after Manuel L. Quezon, the List of presidents of the Philippines, second president of the Philippines. The city was intended to be the Capital of the Philippines, national capital of the Philippines that would replace Manila, as the latter was suffering from overcrowding, lack of housing, poor sanitation, and traffic congestion. To create Quezon City, several barrios were carved out from the towns of Caloocan, Marikina, San Juan, Metro Manila, San Juan and Pasig, in addition to the eight vast estates the Philippine government purchased for this purpose. It was officially proclaimed as the national capital on October 12, 1949, and several government departments and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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.

Questionable Content
''Questionable Content'' (sometimes abbreviated as ''QC'') is a slice-of-life webcomic written and illustrated by Jeph Jacques. It was launched in August 2003 and reached its 4,500th comic in April 2021. The plot originally centered on Marten Reed, an indie rock fan; his anthropomorphized personal computer Pintsize; his roommate, Faye Whitaker; their mutual friend, Dora Bianchi; and their neighbor Hannelore Ellicott-Chatham. However, over time a supporting cast of characters has grown to include employees of the local coffee shop, neighbors, and androids. ''QC'' storytelling style combines romantic melodrama, situational comedy, and sexual humor, while considering questions of relationships, sexuality, dealing with emotional trauma, and artificial intelligence and futurism. Jacques has made his living exclusively from ''QC'' merchandising and advertising. By 2004, Jacques could support himself and his then-fiancée based on income from merchandise and advertising sales.

QuietComfort
Bose Corporation, Bose has sold aviation headset (audio), headsets since 1989 and consumer headphones since 2000. The current range of headphones/headsets consists of over-ear, in-ear, aviation and military models. Over-ear headphones Development of the company's noise-cancelling headphones, noise cancelling headphones (and first Headphones#Circumaural, over-ear headphones) began in 1978 when the chairman, Amar Bose, tried a set of airline-supplied headphones during a flight and found that engine noise from the aircraft prevented the music from being enjoyed. In 1986, Bose and Sennheiser both presented active noise cancelling headsets for aircraft pilots, with the Sennheiser design appearing in a paper and the Bose design appearing in an American Society of Mechanical Engineers, ASME paper. A prototype Bose product was used to prevent hearing loss in pilots during the first non-stop around-the-world flight in the Rutan Voyager. The company was the first to release active noise c ...

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 ...

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 ...

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 introduction Ea ...
