Pacific School Of Religion
The Pacific School of Religion (PSR) is a Private university, private Protestant seminary in Berkeley, California. It maintains Covenant (religion), 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 Christian denomination, 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 Buddhism, Buddhists, Judaism, Jews, Paganism, Pagans, Pentecostalism, Pentecostals, and Catholic Church, Roman Catholics.

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 university, private Ivy League research university in Cambridge, Massachusetts, United States.

Naked And Afraid
''Naked and Afraid'' is an American reality series that airs on the Discovery Channel. Each episode chronicles the lives of two survivalists who meet for the first time naked and are given the task of surviving a stay in the wilderness for 21 days. Each survivalist is allowed to bring one helpful item, such as a machete or a fire starter. After they meet in the assigned location, the partners must build a shelter and find water and food. Synopsis The events of each couple's journey play out in a single episode. Partners strip down and meet each other. They are provided with rough cross-body satchels containing a personal diary/camera, for use when the camera crew is not there at night, and a map. They all wear identical necklaces with a center bead, which is a microphone with a wire that connects to a wireless audio transmitter hidden in the satchel. Some personal jewelry is allowed. Each survivalist is allowed to bring one helpful item, such as a hatchet or a fire starter. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Price–sales Ratio
The price-to-sales ratio (P/S ratio or PSR) is a financial ratio used to assess a company's market value relative to its revenue. It is calculated by dividing the company's market capitalization by its total revenue over a specified period, typically the trailing twelve months (TTM), or equivalently, by dividing the per-share stock price by the per-share revenue. Investors use this metric to gauge how much they are paying for each dollar of a company's sales, often as an alternative to the price-to-earnings ratio (P/E ratio) when earnings are negative or volatile. The P/S ratio is particularly useful for valuing unprofitable companies, as it relies on revenue rather than profit, which may be absent or distorted by accounting practices. A lower ratio (e.g., below 1.0) may suggest a stock is undervalued, while a higher ratio could indicate overvaluation, though interpretation depends on industry norms and company context. The ratio can also track a stock’s valuation over time or ... [...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 American railroad executive E. Hunter Harrison in 1993 and has since been 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 emphasizing 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 freight transport, 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 an often substantial decrease in railroad op ...

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] |
Portuguese Sign Language
Portuguese Sign language () is a sign language used mainly by deaf people in Portugal. It is recognized in the present Constitution of Portugal. It was significantly influenced by Swedish Sign Language, through a deaf education, school for the Deaf that was established in Lisbon by Swedish educator Pär Aron Borg. Portuguese Sign is the basis of Cape Verdian Sign Language, Cape Verdian Sign, and it has also slightly influenced Guinea-Bissau Sign Language, Guinea-Bissau Sign. Some reports have said that São Tomé and Príncipe Sign Language has considerable mutual intelligibility with Portuguese Sign. It is also reported that Portuguese Sign has been also used in Angola. History The Portuguese Sign Language has its origins from the Swedish Sign Language (LGS), as in the 19th century, the king called to Portugal Pär Aron Borg, a Swede who had founded an institute for the education of the deaf in Sweden. In 1823, the first school for the deaf was made in Portugal. Although many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PSR-90
The PSR-90 (Precision Sniper Rifle) is a Pakistani semi-automatic 7.62×51mm precision rifle designed and manufactured by Pakistan Ordnance Factories.

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 round such as .300 Win Mag and .338 Lapua Magnum. The solicitation was placed on January 15, 2009. The contract was awarded to the Remington Modular Sniper Rifle and was designated the 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 w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embedded DisplayPort
DisplayPort (DP) is a digital interface used to connect a video source, such as a computer, to a display device like a monitor. Developed by the Video Electronics Standards Association (VESA), it can also carry digital audio, USB, and other types of data over a single cable. Introduced in the 2000s, DisplayPort was designed to replace older standards like VGA, DVI, and FPD-Link. While not directly compatible with these formats, adapters are available for connecting to HDMI, DVI, VGA, and other interfaces. Unlike older interfaces, DisplayPort uses packet-based transmission, similar to how data is sent over USB or Ethernet. The design enables support for high resolutions and adding new features without changing the connector. DisplayPort includes an auxiliary data channel used for device control and automatic configuration between source and display devices. It supports standards such as Display Data Channel (DDC), Extended Display Identification Data (EDID), Monitor Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Kinshumann is the original architect of WER. WER was also included in the Association for Computing Machinery (ACM) hall of fame for its impact o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 a Function (mathematics), function that gives the probabilities of occurrence of possible events for an Experiment (proba ...
