Providence And Worcester Railroad
The Providence and Worcester Railroad is a Class II railroad operating of tracks in Rhode Island, Massachusetts, and Connecticut, as well as New York via trackage rights. The company was founded in 1844 to build a railroad between Providence, Rhode Island, and Worcester, Massachusetts, and ran its first trains in 1847. A successful railroad, the P&W subsequently expanded with a branch to East Providence, Rhode Island, and for a time leased two small Massachusetts railroads. Originally operating on a single track, its busy mainline was double-tracked beginning in 1853, following a fatal collision that year in Valley Falls, Rhode Island. The P&W operated independently until 1888, when the New York, Providence and Boston Railroad (NYP&B) leased it; the New York, New Haven and Hartford Railroad obtained the lease in 1892 when it purchased the NYP&B. The P&W continued to exist as a company, as special rules protecting minority shareholders made it prohibitively expensive for th ...

Pseudo-wire
In computer networking and telecommunications, a pseudowire (or pseudo-wire) is an emulation of a point-to-point connection over a packet-switched network (PSN). The pseudowire emulates the operation of a "transparent wire" carrying the service, but it is realized that this emulation will rarely be perfect. The service being carried over the "wire" may be Asynchronous Transfer Mode (ATM), Frame Relay, Ethernet or time-division multiplexing (TDM) while the packet network may be Multi-protocol Label Switching (MPLS), Internet Protocol (IPv4 or IPv6), or Layer 2 Tunneling Protocol Version 3 (L2TPv3). The first pseudowire specifications were the Martini draft for ATM pseudowires, and the TDMoIP draft for transport of E1/T1 over IP. In 2001, the Internet Engineering Task Force (IETF) set up the PWE3 working group, which was chartered to develop an architecture for service provider edge-to-edge pseudowires, and service-specific documents detailing the encapsulation techniques.

Precipitable Water
Precipitable water is the depth of water in a column of the atmosphere, if all the water in that column were precipitated as rain. As a depth, the precipitable water is measured in millimeters or inches. Often abbreviated as "TPW", for Total Precipitable Water. Measurement There are different measurement techniques: *One type of measurement is based on the measurement of the solar irradiance on two wavelengths, one in a water absorption band, and the other not. The precipitable water column is determined using the irradiances in these bands and the Beer–Lambert law. *The precipitable water can also be calculated by integration of radiosonde data (relative humidity, pressure and temperature) over the whole atmosphere. *Data can be viewed on a Lifted-K index. The numbers represent inches of water as mentioned above for a geographical location. *Recently, methods using the Global Positioning System have been developed. *Some work has been performed to create empirical relationshi ...

Picowatt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : \mathr ...

Pennyweight
A pennyweight (dwt) is a unit of mass equal to 24 grains, of a troy ounce, of a troy pound, approximately 0.054857 avoirdupois ounce and exactly 1.55517384 grams. It is abbreviated dwt, ''d'' standing for ''denarius'' (an ancient Roman coin), and later used as the symbol of an old British penny (see £sd). History In the Middle Ages, an English penny's weight was literally, as well as monetarily, of an ounce and of a pound of sterling silver. At that time, the pound unit in use in England was the Tower pound, equal to 7,680 Tower grains (also known as wheat grains). The medieval English pennyweight was thus equal to 32 Tower grains. When Troy weights replaced Tower weights in 1527, the Troy weights were defined in such a way that the old Tower pound came out to exactly 5,400 Troy grains (also known as barleycorns), the Tower pennyweight Troy grains (and thus approximately 1.46 grams). After 1527, the English pennyweight was the Troy pennyweight. of 24 Tro ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pathetic Writer
Siag Office is a tightly integrated free software office package for Unix-like operating systems. It consists of the spreadsheet SIAG ("Scheme In A Grid"), the word processor Pathetic Writer (PW), the animation program Egon Animator, the text editor XedPlus, the file manager Xfiler and the previewer Gvu. Siag Office is known to be extremely light-weight, hence able to run on very old systems reasonably well, such as on i486 computers with 16MB RAM. Because it is kept light-weight, the software lacks many of the features of major office suites, like LibreOffice, Calligra Suite, or Microsoft Office. Siag Office is distributed under the terms of the GPL-2.0-or-later license. Version 3.6.0 was released in 2003, and the latest version 3.6.1 was released in 2006. Siag Office is included in Damn Small Linux, a lightweight Linux distribution. Components Siag Siag is the spreadsheet based on the X Window System and the Scheme programming language (specifically using home-grown variant ...

Password
A password, sometimes called a passcode (for example in Apple devices), is secret data, typically a string of characters, usually used to confirm a user's identity. Traditionally, passwords were expected to be memorized, but the large number of password-protected services that a typical individual accesses can make memorization of unique passwords for each service impractical. Using the terminology of the NIST Digital Identity Guidelines, the secret is held by a party called the ''claimant'' while the party verifying the identity of the claimant is called the ''verifier''. When the claimant successfully demonstrates knowledge of the password to the verifier through an established authentication protocol, the verifier is able to infer the claimant's identity. In general, a password is an arbitrary string of characters including letters, digits, or other symbols. If the permissible characters are constrained to be numeric, the corresponding secret is sometimes called a personal i ...
