Pressure Wave Supercharger
A pressure wave supercharger (also known as a wave rotor) is a type of supercharger technology that harnesses the pressure waves produced by an internal combustion engine exhaust gas pulses to compress the intake air. Its automotive use is not widespread; the most widely used example is the ''Comprex'', developed by Brown Boveri.A Review of Wave Rotor Technology and its Applications including details of Comprex supercharger Valmet Tractors of Finland were one of the first to use the device when they fitted it to the 411CX engine which powered their 1203 model of 1980. Although it provided a useful increase in performance it was considered too expensive to be incorporated into later models. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Performance Work Statement
A Performance work statement (or PWS) is used to summarize the work that needs to be done for a contract (e.g., with the U.S. Department of Defense). A PWS usually requires a scope, applicable documents, performance requirements/tasks, and contractor quality assurance Quality assurance (QA) is the term used in both manufacturing and service industries to describe the systematic efforts taken to ensure that the product(s) delivered to customer(s) meet with the contractual and other agreed upon performance, design ... for acquisition.

Personal Weather Station
A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate. The measurements taken include temperature, atmospheric pressure, humidity, wind speed, wind direction, and precipitation amounts. Wind measurements are taken with as few other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation. Manual observations are taken at least once daily, while automated measurements are taken at least once an hour. Weather conditions out at sea are taken by ships and buoys, which measure slightly different meteorological quantities such as sea surface temperature (SST), wave height, and wave period. Drifting weather buoys outnumber their moored versions by a significant amount. Weather instruments Typical weather stations have the following instruments: * Thermometer for ...

Personal Web Server
A personal web server (PWS) is system of hardware and software that is designed to create and manage a web server on a desktop computer. It can be used to learn how to set up and administer a website, and it can also serve as a site for testing dynamic web pages. One of the main functions of PWS is to provide an environment where web programmers can test their programs and web pages. Therefore, a PWS supports the more common server-side programming approaches that can be used with production web servers. A personal web server, or personal server in short, allows users to store, selectively share, or publish information on the web or on a home network. Unlike other types of web servers, a personal web server is owned or controlled by an individual, and operated for the individual's needs, instead of by a company. It can be implemented in different ways: * as a computer appliance * as a general-purpose server, such as a Linux server, which may be located at the owner's home or in a ...

Microsoft Personal Web Server
Microsoft Personal Web Server (PWS) is a scaled-down web server software for Windows operating systems. It has fewer features than Microsoft's Internet Information Services (IIS) and its functions have been superseded by IIS and Visual Studio. Microsoft officially supports PWS on Windows 95- 98, Windows 98 SE, and Windows NT 4.0. Prior to the release of Windows 2000, PWS was available as a free download as well as included on the Windows distribution CDs. PWS 4 was the last version and it can be found on the Windows 98 CD and the Windows NT 4.0 Option Pack. Personal Web Server was originally created by Vermeer Technologies, the same company which created Microsoft FrontPage, before they were acquired by Microsoft. It was installed by FrontPage versions 1.1 to 98 as well. NT Workstation 4.0 shipped with Peer Web Services, which was based on IIS 2.0 and 3.0. With IIS 4.0, this was renamed Personal Web Server to be consistent with the name used in 95/98. Since Windows 2000, PWS w ...

Present Weather Sensor
The present weather sensor (PWS) is a component of an automatic weather station that detects the presence of hydrometeors and determines their type (rain, snow, drizzle, etc.) and intensity. It works on a principle similar to a bistatic radar, noting the passage of droplets, or flakes, between a transmitter and a sensor. These instruments in automatic weather stations are used to simulate the observation taken by a human observer. They allow rapid reporting of any change in the type and intensity of precipitation, but include interpretation limitations. Principle Types There are at least two types of devices used to detect precipitation: * A ''light emitting diode weather identifier'' (''LEDWI'') sensor measures the scintillation pattern of the precipitation falling through the sensor's infrared beam (approximately 50 millimeters in diameter) and determines from a pattern analysis of the particle size and fall velocity whether the precipitation is rain or snow. * The ''POSS'' ...

Professional Wetland Scientist
A professional is a member of a profession or any person who works in a specified professional activity. The term also describes the standards of education and training that prepare members of the profession with the particular knowledge and skills necessary to perform their specific role within that profession. In addition, most professionals are subject to strict codes of conduct, enshrining rigorous ethical and moral obligations. Professional standards of practice and ethics for a particular field are typically agreed upon and maintained through widely recognized professional associations, such as the IEEE. Some definitions of "professional" limit this term to those professions that serve some important aspect of public interest and the general good of society.Sullivan, William M. (2nd ed. 2005).

Public Warning System
An emergency population warning is a method whereby local, regional, or national authorities can contact members of the public en masse to warn them of an impending emergency. These warnings may be necessary for a number of reasons, including: * weather emergencies such as tornadoes, hurricanes, and ice storms; * geological disasters such as earthquakes, landslides, volcanic eruptions, and tsunamis; * industrial disasters such as the release of toxic gas or contamination of river water; * radiological disasters such as a nuclear plant disaster; * medical emergencies such as an outbreak of a fast-moving infectious disease; * warfare or acts of terrorism. Many local areas use emergency population warnings to advise of prison escapes, abducted children, emergency telephone number outages, and other events. Requirements In order to develop an effective emergency warning system, certain things are required: * an agreement as to what constitutes an emergency in the area served by ...

Podlaska Wytwórnia Samolotów
Podlaska Wytwórnia Samolotów (PWS) - ''Podlasie Aircraft Factory'' - was a Polish aerospace manufacturer between 1923 and 1939, located in Biała Podlaska. History Podlaska Wytwórnia Samolotów SA was created in 1923. The first aircraft produced were 35 Potez 15 bombers for the Polish Air Force, under the French licence, built from 1925.Glass, A. (1977), p.22-25 By 1929 the works had produced 155 Potez 27 and 150 Potez 25, under French licence, and 50 PWS-A fighters, which was the Czech Avia BH-33 built under licence. It also produced 50 Bartel BM-4 trainers in 1931, designed by Samolot. In 1925, a design office was established which included, among others, Stefan Cywiński, Zbysław Ciołkosz, August Bobek-Zdaniewski. Despite a large number of prototypes, few were produced in series. The first aircraft of their own design to be mass-produced was the PWS-10 fighter of 1930 of which 80 examples were built. Smaller production runs of the PWS-14 trainer and the PWS-24 pass ...

Prader–Willi Syndrome
Prader–Willi syndrome (PWS) is a genetic disorder caused by a loss of function of specific genes on chromosome 15. In newborns, symptoms include weak muscles, poor feeding, and slow development. Beginning in childhood, those affected become constantly hungry, which often leads to obesity and type 2 diabetes. Mild to moderate intellectual impairment and behavioral problems are also typical of the disorder. Often, affected individuals have a narrow forehead, small hands and feet, short height, and light skin and hair. Most are unable to have children. About 74% of cases occur when part of the father's chromosome 15 is deleted. In another 25% of cases, the affected person has two copies of the maternal chromosome 15 from the mother and lacks the paternal copy. As parts of the chromosome from the mother are turned off through imprinting, they end up with no working copies of certain genes. PWS is not generally inherited, but rather the genetic changes happen during the format ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winston Smith Project
The Winston Smith Project ( it, Progetto Winston Smith, or PWS) is an informational and operational project for the defence of human rights on the Internet and in the digital era. The project was started in 1999 as an anonymous association and it is characterised by the absence of a physical reference identity. It is named after the main character in George Orwell's novel "Nineteen Eighty-Four". The reference to Orwell's dystopia is embodied in the motto of PWS: "Unplug the Big Brother" which is aligned with its more generalist motto "Paranoia is a virtue". PWS aims to make users aware of the risks of violation of privacy on the Internet and threats to freedom of speech. PWS is engaged in spreading the informational tools and counter-censorship technologies that allow users to maintain confidentiality in their communications, anonymity in the network and freedom of expression. PWS has generated and maintains the ''e-privacy'', ''Big Brother Awards Italy'', ''Privacy Box'' and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
