Probability Of Kill
Computer games, simulations, mathematical model, models, and operations research programs often require a mechanism to determine statistically how likely the engagement between a weapon and a target will result in a satisfactory outcome (i.e. "kill"), known as the probability of kill. Performance auditing and statistical decisions are required when all of the variables that must be considered are not incorporated into the current model, similar to the actuarial methods used by insurance companies to deal with large numbers of customers and huge numbers of variables. Likewise, military planning, military planners rely on such calculations to determine the quantity of weapons necessary to destroy an enemy force. The probability of kill, or "Pk", is usually based on a uniform random number generation, random number generator. This algorithm creates a number between 0 and 1 that is approximately uniformly distributed in that space. If the Pk of a weapon/target engagement is 30% (or 0.30 ...

Possum Kingdom Lake
Possum Kingdom Lake (popularly known as P.K.), is a reservoir on the Brazos River located primarily in Palo Pinto County, TX, Palo Pinto County Texas. It was the first water supply reservoir constructed in the Brazos River basin. The lake has an area of approximately with of shoreline. It holds of water with available for water supply. The lake is impounded by the Morris Sheppard Dam, which was a project of the Brazos River Authority and the Works Progress Administration. Construction was begun in 1936 and completed in 1941. The dam is long and high. The construction is unique with buttressed arched wings on either side of the nine spillway gates rather than the usual filled concrete. It has two 11,250 kilowatt generators which were used during peak demand periods that are no longer in use. Morris Sheppard was in 1938 one of Texas' United States Senators. The dam was named for him in honor of his efforts in obtaining funding for the project. The lake is located wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parkour
Parkour () is an athletic training discipline or sport in which practitioners (called ''traceurs'') attempt to get from point A to point B in the fastest and most efficient way possible, without assisting equipment and often while performing artistic-gymnastic maneuvers. With roots in military obstacle course training and martial arts, parkour includes running, climbing, swinging, vaulting, jumping, plyometrics, rolling, gymnastics, and quadrupedal movement—whatever is suitable for a given situation. Parkour is an activity that can be practiced alone or with others, and is usually carried out in urban spaces, though it can be done anywhere. It involves seeing one's environment in a new way, and envisioning the potential for navigating it by movement around, across, through, over and under its features. Although practitioners of Parkour often perform flips and other acrobatic movements, these are not considered a part of Parkour proper. The practice of similar movements had ...

Renault PK
The P.K was a car made by Pars Khodro between 2000 and 2005 using the body of the first-generation Renault 5 and the engine of the Kia Pride. "P.K" is an acronym for Pars Khodro. After 24 years of manufacture of the Renault 5 as the Sepand in Iran by SAIPA then Pars Khodro from 1976 to 2000, Pars Khodro updated the model with a Renault 5 body and kia pride engine. The Renault 5 bodywork was further modified and additional amenities were added, such as air conditioning. The result was the P.K. Manufacture of the P.K continued until it was replaced by the New P.K in 2005. New P.K. The New P.K. is a car made by Pars Khodro, with a body similar to a first generation Renault 5 and the platform/engine of a Kia Pride. P.K is an acronym for Pars Khodro (the manufacturer). Manufacture of the New P.K. commenced in 2005. The New P.K is different in body style from the previous P.K. models which had a very similar body to the Renault 5 The Renault 5 is a four-passenger, three or five-doo ...

Pentax K-mount
The Pentax K-mount, sometimes referred to as the "PK-mount", is a bayonet lens mount standard for mounting interchangeable photographic lenses to 35 mm single-lens reflex (SLR) cameras. It was created by Pentax in 1975, and has since been used by all Pentax 35 mm and digital SLRs and also the MILC Pentax K-01. A number of other manufacturers have also produced many K-mount lenses and K-mount cameras. Mounts The Pentax K-mount has undergone a number of evolutions over the years as new functionality has been added. In general, the term K-mount may refer to the original K-mount, or to all its variations. Originally designed by Zeiss for an alliance with Pentax, it was intended to be a common lens mount for a proposed series of cameras and lenses. However, the plan failed to work out and the two firms parted company amicably, but Pentax retained the lens mount and at least one Zeiss lens design for its own use. K-mount The original K-mount is a simple bayonet con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...

PK Machine Gun
The PK (russian: Пулемёт Калашникова, transliterated as ''Pulemyot Kalashnikova'', or "Kalashnikov's machine gun"), is a belt-fed general-purpose machine gun, chambered for the 7.62×54mmR rimmed cartridge. Designed in the Soviet Union and currently in production in Russia, the original PK machine gun was introduced in 1961 and the improved PKM variant was introduced in 1969. The PKM was designed to replace the SGM and RP-46 machine guns that were previously in Soviet service. The weapon remains in use as a front-line infantry and vehicle-mounted weapon with Russia's armed forces and has also been exported extensively and produced in several other countries under license. History The Main Artillery Directorate of the Soviet Union (GRAU) adopted specification requirements for a new 7.62 mm general-purpose company and battalion-level machine gun that was to be chambered for a rifle cartridge in 1955. In 1958 a machine gun prototype, developed by G.I. Nik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public-key Cryptography
Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions. Security of public-key cryptography depends on keeping the private key secret; the public key can be openly distributed without compromising security. In a public-key encryption system, anyone with a public key can encrypt a message, yielding a ciphertext, but only those who know the corresponding private key can decrypt the ciphertext to obtain the original message. For example, a journalist can publish the public key of an encryption key pair on a web site so that sources can send secret messages to the news organization in ciphertext. Only the journalist who knows the corresponding private key can decrypt the ciphertexts to obtain the sources' messages—an eavesdropp ...

Port Knocking
In computer networking, port knocking is a method of externally opening ports on a firewall by generating a connection attempt on a set of prespecified closed ports. Once a correct sequence of connection attempts is received, the firewall rules are dynamically modified to allow the host which sent the connection attempts to connect over specific port(s). A variant called single packet authorization (SPA) exists, where only a single "knock" is needed, consisting of an encrypted packet. The primary purpose of port knocking is to prevent an attacker from scanning a system for potentially exploitable services by doing a port scan, because unless the attacker sends the correct knock sequence, the protected ports will appear closed. Overview Port knocking is usually implemented by configuring a daemon to watch the firewall log file for connection attempts to certain points, and then to modify the firewall configuration accordingly. It can also be performed on the kernel level (using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zip (file Format)
ZIP is an archive file format that supports lossless data compression. A ZIP file may contain one or more files or directories that may have been compressed. The ZIP file format permits a number of compression algorithms, though DEFLATE is the most common. This format was originally created in 1989 and was first implemented in PKWARE, Inc.'s PKZIP utility, as a replacement for the previous ARC compression format by Thom Henderson. The ZIP format was then quickly supported by many software utilities other than PKZIP. Microsoft has included built-in ZIP support (under the name "compressed folders") in versions of Microsoft Windows since 1998 via the "Windows Plus!" addon for Windows 98. Native support was added as of the year 2000 in Windows ME. Apple has included built-in ZIP support in Mac OS X 10.3 (via BOMArchiveHelper, now Archive Utility) and later. Most free operating systems have built in support for ZIP in similar manners to Windows and Mac OS X. ZIP files ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pharmacokinetics
Pharmacokinetics (from Ancient Greek ''pharmakon'' "drug" and ''kinetikos'' "moving, putting in motion"; see chemical kinetics), sometimes abbreviated as PK, is a branch of pharmacology dedicated to determining the fate of substances administered to a living organism. The substances of interest include any chemical xenobiotic such as: pharmaceutical drugs, pesticides, food additives, cosmetics, etc. It attempts to analyze chemical metabolism and to discover the fate of a chemical from the moment that it is administered up to the point at which it is completely eliminated from the body. Pharmacokinetics is the study of how an organism affects a drug, whereas pharmacodynamics (PD) is the study of how the drug affects the organism. Both together influence dosing, benefit, and adverse effects, as seen in PK/PD models. Overview Pharmacokinetics describes how the body affects a specific xenobiotic/chemical after administration through the mechanisms of absorption and distribution, as ...
