QS World University Rankings
The ''QS World University Rankings'' is a portfolio of comparative college and university rankings compiled by Quacquarelli Symonds, a higher education analytics firm. Its first and earliest edition was published in collaboration with '' Times Higher Education'' (''THE'') magazine as ''Times Higher Education''–QS World University Rankings, inaugurated in 2004 to provide an independent source of comparative data about university performance. In 2009, the two organizations parted ways to produce independent university rankings, the QS World University Rankings and ''THE'' World University Rankings. QS's rankings portfolio has since been expanded to consist of the QS World University Rankings, the QS World University Rankings by Subject, four regional rankings tables (including Asia, Latin America and The Caribbean, Europe, and the Arab Region), several MBA rankings, and the QS Best Student Cities rankings. In 2022, QS launched the QS World University Rankings: Sustainability ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quadraphonic Sound
Quadraphonic (or quadrophonic, also called quadrasonic or by the neologism quadio formed by analogy with "stereo"">portmanteau.html" ;"title="/nowiki>portmanteau">formed by analogy with "stereo" sound – equivalent to what is now called 4.0 surround sound – uses four audio channels in which speakers are positioned at the four corners of a listening space. The system allows for the reproduction of sound signals that are (wholly or in part) independent of one another. Four channel quadraphonic surround sound can be used to recreate the highly realistic effect of a three-dimensional live concert hall experience in the home. It can also be used to enhance the listener experience beyond the directional limitations of ordinary two channel stereo sound. Quadraphonic audio was the earliest consumer product in surround sound. Since it was introduced to the public in the early 1970s many thousands of quadraphonic recordings have been made. Quadraphonic sound was a commercial failure ...

Quadratic Sieve
The quadratic sieve algorithm (QS) is an integer factorization algorithm and, in practice, the second-fastest method known (after the general number field sieve). It is still the fastest for integers under 100 decimal digits or so, and is considerably simpler than the number field sieve. It is a general-purpose factorization algorithm, meaning that its running time depends solely on the size of the integer to be factored, and not on special structure or properties. It was invented by Carl Pomerance in 1981 as an improvement to Schroeppel's linear sieve. Basic aim The algorithm attempts to set up a congruence of squares modulo ''n'' (the integer to be factorized), which often leads to a factorization of ''n''. The algorithm works in two phases: the ''data collection'' phase, where it collects information that may lead to a congruence of squares; and the ''data processing'' phase, where it puts all the data it has collected into a matrix and solves it to obtain a congruence of squ ...

Quantity Surveyor
In the construction industry, a quantity surveyor (QS) is a professional with expert knowledge of construction costs and contracting. Qualified professional quantity surveyors can be known as Chartered Surveyors (Members and Fellows of RICS) in the UK and Certified Quantity Surveyors (a designation of the Australian Institute of Quantity Surveyors) in Australia and other countries. In some countries, including Canada, South Africa, Kenya and Mauritius, qualified quantity surveyors are known as Professional Quantity Surveyors, a title protected by law. Due to a shift in the construction industry and the increased demand for Quantity Surveying expertise, today less importance is being placed on Charterships, with a large percentage of working Quantity Surveyors practising with College / University degrees and without membership or fellowship to professional associations. Quantity surveyors are responsible for managing all aspects of the contractual and financial side of construct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quorum Sensing
In biology, quorum sensing or quorum signaling (QS) is the process of cell-to-cell communication that allows bacteria to detect and respond to cell population density by gene regulation, typically as a means of acclimating to environmental disadvantages. Quorum sensing is a type of cellular signaling, and can be more specifically considered a type of paracrine signaling. However, it also contains traits of autocrine signaling: a cell produces both an autoinducer molecule and the receptor for the autoinducer. As one example, quorum sensing enables bacteria to restrict the expression of specific genes to the high cell densities at which the resulting phenotypes will be most beneficial, especially for phenotypes that would be ineffective at low cell densities and therefore too energetically costly to express. Many species of bacteria use quorum sensing to coordinate gene expression according to the density of their local population. In a similar fashion, some social insects use q ...

Quality Start
In baseball, a quality start (QS) is a statistic for a starting pitcher defined as a game in which the pitcher completes at least six innings and permits no more than three earned runs. The quality start was developed by sportswriter John Lowe in 1985 while writing for ''The Philadelphia Inquirer''. He wrote that it "shows exactly how many times a baseball pitcher has done his job." The quality start was created to be an accurate measure of a starting pitcher's performance. However, the implied earned run average (ERA) of a minimum quality start has been criticized, with Tim McCarver noting "three runs for six innings ... means the ERA would be 4.50 ... Rubbish." MLB quality start leaders This section lists quality start leaders in Major League Baseball (MLB). ESPN.com includes quality starts in its "Stat Leaders" section, and terms a loss suffered by a pitcher in a quality start as a "tough loss" and a win earned by a pitcher in a non-quality start a "cheap win".

QS Mark
The QS mark (from Qiye Shipin shengchan xuke, meaning authorised manufacturing for enterprises, formally the Industrial Product Manufacturing License) is a Chinese quality and safety mark for food, beverages and other products. Introduced in 2003, it is managed by the General Administration of Quality Supervision, Inspection and Quarantine (GAQSIQ). The license is required for many product categories if they are both manufactured and sold in China. The mark was‘as deprecated in October 2018, and replaced with the SC system, which consists of the letters SC followed by a 14 digit number. SC means Sheng Chan (manufacturing) and the number is partially unique to each food processing facility. The first three digits represent the food category, the next two digits represent the province, the 6th and 7th digits represent the city, the 8th and 9th the district, the 10th to 13th are the sequence code for the production license, which is unique and has to be renewed every 5 years, and t ...

Quality Management System
A quality management system (QMS) is a collection of business processes focused on consistently meeting customer requirements and enhancing their satisfaction. It is aligned with an organization's purpose and strategic direction ( ISO 9001:2015). It is expressed as the organizational goals and aspirations, policies, processes, documented information, and resources needed to implement and maintain it. Early quality management systems emphasized predictable outcomes of an industrial product production line, using simple statistics and random sampling. By the 20th century, labor inputs were typically the most costly inputs in most industrialized societies, so focus shifted to team cooperation and dynamics, especially the early signaling of problems via a continual improvement cycle. In the 21st century, QMS has tended to converge with sustainability and transparency initiatives, as both investor and customer satisfaction and perceived quality are increasingly tied to these factors. ...
