Pacific School Of Religion
The Pacific School of Religion (PSR) is a private Protestant seminary in Berkeley, California. It maintains covenantal relationships with the United Church of Christ, the United Methodist Church, and the Disciples of Christ, ensuring the school provides the necessary requirements for candidates to seek ordination within these denominations. These three denominations account for approximately half of the student population of PSR. The school has also maintained close relationships with the Unitarian Universalist Association, the Universal Fellowship of Metropolitan Community Churches, the African Methodist Episcopal Church, as well as other denominations. Over the years PSR has provided training for clergy and leaders from a wide range of religious traditions including Buddhists, Jews, Pagans, Pentecostals, and Roman Catholics. History The Pacific School of Religion was founded in San Francisco, California, in 1866 as the Pacific Theological Seminary, making PSR the oldest P ...

Predictive State Representation
In computer science, a predictive state representation (PSR) is a way to model a state of controlled dynamical system from a history of actions taken and resulting observations. PSR captures the state of a system as a vector of predictions for future tests (experiments) that can be done on the system. A test is a sequence of action-observation pairs and its prediction is the probability of the test's observation-sequence happening if the test's action-sequence were to be executed on the system. One of the advantage of using PSR is that the predictions are directly related to observable quantities. This is in contrast to other models of dynamical systems, such as partially observable Markov decision processes (POMDPs) where the state of the system is represented as a probability distribution In probability theory and statistics, a probability distribution is the mathematical function that gives the probabilities of occurrence of different possible outcomes for an experiment. ...

Price–sales Ratio
Price–sales ratio, P/S ratio, or PSR, is a valuation metric for stocks. It is calculated by dividing the company's market capitalization by the revenue in the most recent year; or, equivalently, divide the per-share stock price by the per-share revenue. :\text = \frac = \frac The justified P/S ratio is calculated as the price-to-sales ratio based on the Gordon Growth Model. Thus, it is the price-to-sales ratio based on the company's fundamentals rather than . Here, is the sustainable growth rate as defined below and is the required rate of return. :\text = \text \times \text \times \frac Where g = \text \times \text \times \frac \times \frac. Unless otherwise stated, P/S is "trailing twelve months" (TTM), the reported sales for the four previous quarters, although of course longer time periods can be examined. The smaller this ratio (i.e. less than 1.0) is usually thought to be a better investment since the investor is paying less for each unit of sales. However, sales ...

Rail Freight Transport
Rail freight transport is the use of railroads and trains to transport cargo as opposed to human passengers. A freight train, cargo train, or goods train is a group of freight cars (US) or goods wagons (International Union of Railways) hauled by one or more locomotives on a railway, transporting cargo all or some of the way between the shipper and the intended destination as part of the logistics chain. Trains may haul bulk material, intermodal containers, general freight or specialized freight in purpose-designed cars. Rail freight practices and economics vary by country and region. When considered in terms of ton-miles or tonne-kilometers hauled per unit of energy consumed, rail transport can be more efficient than other means of transportation. Maximum economies are typically realized with bulk commodities (e.g., coal), especially when hauled over long distances. However, shipment by rail is not as flexible as by the highway, which has resulted in much freight being h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precision Scheduled Railroading
Precision railroading or precision scheduled railroading (PSR) is a concept in freight railroad operations pioneered by E. Hunter Harrison in 1993, and adopted by nearly every North American Class I railroad. It shifts the focus from older practices, such as unit trains, hub and spoke operations and individual car switching at hump yards, to emphasize point-to-point freight car movements on simplified routing networks. Under PSR, freight trains operate on fixed schedules, much like passenger trains, instead of being dispatched whenever a sufficient number of loaded cars are available. In the past, intermodal trains and general merchandise trains operated separately; under PSR they are combined as needed, typically with distributed power. Inventories of freight cars and locomotives are reduced and fewer workers are employed for a given level of traffic. The result is often substantial improvement in railroad operating ratios, and other financial and operating metrics; at the cost ...

Potential Support Ratio
The potential support ratio (PSR) is the number of people age 15–64 per one older person aged 65 or older. This ratio describes the burden placed on the working population (unemployment and children are not considered in this measure) by the non-working elderly population.World Population Ageing 1950-2050, p 4Definition of the Indicators of Population Ageing/ref> As a population ages, the potential support ratio tends to fall. Between 1950 and 2009, the potential ratio declined from 12 to 9 potential workers per person aged 65 or over. By 2050, the potential support ratio is projected to drop further to reach 4 potential worker per older person. The reduction of potential support ratio has important implications for social security schemes, particularly for pay-as-you-go pension systems under which taxes on current workers pay the pensions of retirees. In 2015, Japan has the lowest PSR in the world, at 1.8. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Precision Sniper Rifle
The Precision Sniper Rifle (PSR) was a program by United States Special Operations Command to replace all bolt-action sniper rifles in use by United States special operations snipers with a single bolt-action rifle chambered for a large caliber Magnum chambering like .300 Win Mag, and .338 Lapua Magnum. The solicitation was placed on January 15, 2009. The contract was awarded to Remington Arms for their Modular Sniper Rifle as Mk 21 Precision Sniper Rifle History A 2008 United States military market survey for a Precision Sniper Rifle (PSR) called for 1 minute of arc (0.3 milliradian) extreme vertical spread for all shots in a 5-round group fired at targets at 300, 600, 900, 1,200 and 1,500 meters. In 2009 a United States Special Operations Command market survey called for 1 MOA (0.3 mrad) extreme vertical spread for all shots in a 10-round group fired at targets at 300, 600, 900, 1,200 and 1,500 meters. The 2009 Precision Sniper Rifle requirements stated that the PSR when f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embedded DisplayPort
DisplayPort (DP) is a digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). It is primarily used to connect a video source to a display device such as a computer monitor. It can also carry audio, USB, and other forms of data. DisplayPort was designed to replace VGA, FPD-Link, and Digital Visual Interface (DVI). It is backward compatible with other interfaces, such as HDMI and DVI, through the use of either active or passive adapters. It is the first display interface to rely on packetized data transmission, a form of digital communication found in technologies such as Ethernet, USB, and PCI Express. It permits the use of internal and external display connections. Unlike legacy standards that transmit a clock signal with each output, its protocol is based on small data packets known as ''micro packets'', which can embed the clock signal in the data stream, allowing higher resoluti ...

Problem Steps Recorder
Windows Error Reporting (WER) (codenamed Watson) is a crash reporting technology introduced by Microsoft with Windows XP and included in later Windows versions and Windows Mobile 5.0 and 6.0. Not to be confused with the Dr. Watson debugging tool which left the memory dump on the user's local machine, Windows Error Reporting collects and offers to send post-error debug information (a memory dump) using the Internet to Microsoft when an application crashes or stops responding on a user's desktop. No data is sent without the user's consent. When a crash dump (or other error signature information) reaches the Microsoft server, it is analyzed, and information about a solution is sent back to the user if available. Solutions are served using Windows Error Reporting Responses. Windows Error Reporting runs as a Windows service. Kinshuman is the original architect of WER. WER was also included in the ACM hall of fame for its impact on the computing industry. History Windows XP ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PHP Standard Recommendation
The PHP Standard Recommendation (PSR) is a PHP specification published by the PHP Framework Interop Group. Similar to Java Specification Request for Java, it serves the standardization of programming concepts in PHP. The aim is to enable interoperability of components and to provide a common technical basis for implementation of proven concepts for optimal programming and testing practices. The PHP-FIG is formed by several PHP frameworks founders. Each PSR is suggested by members and voted according to an established protocol to act consistently and in line with their agreed upon processes. The PHP-FIG official website has the PSR documentation that follows the RFC 2119 written by Scott Bradner in March 1997 at Harvard University Harvard University is a private Ivy League research university in Cambridge, Massachusetts.
