Adygeya Airlines
Adygea Airlines (russian: Авиалинии Адыгеи, Avialinii Adygei) was the state-owned national airline of the republic of Adygea, in Russia Russia (, , ), or the Russian Federation, is a transcontinental country spanning Eastern Europe and Northern Asia. It is the largest country in the world, with its internationally recognised territory covering , and encompassing one-eigh .... The company was founded in 1997 and liquidated at the end of 2009. Liquidation In 2008 the airline went into liquidation while the government sought an investor. Aeroflot showed interest but did not take the airline over. There was an initial attempt to sell off all assets to one buyer (at a value of 61.9 million Roubles in November 2009) but this was then divided into different lots - the airport (starting price of 21 million Roubles), aircraft maintenance base (16 million Roubles), oil base (6 million Roubles) and the aircraft each individually priced.

Radar Detector Detector
A radar detector detector (RDD) is a device used by police or law enforcement in areas where radar detectors are declared illegal. Radar detectors are built around a superheterodyne receiver, which has a local oscillator that radiates slightly. It is therefore possible to build a radar-detector detector, which detects such emissions (usually the frequency of the radar type being detected, plus about 10 MHz for the intermediate frequency). Some radar guns are equipped with such a device. However, like any device that detects stray emissions from electronic equipment, it is easily defeated by using adequate shielding. History The VG-2 Interceptor was the first device developed for this purpose, although more current technology such as the Spectre III (Stalcar in Australia) is now available. This form of "electronic warfare" cuts both ways and since detector-detectors use a similar superheterodyne receiver, many early "stealth" radar detectors were equipped with a radar- ...

Radiological Dispersion Device
A dirty bomb or radiological dispersal device is a radiological weapon that combines radioactive material with conventional explosives. The purpose of the weapon is to contaminate the area around the dispersal agent/conventional explosion with radioactive material, serving primarily as an area denial device against civilians. It is not to be confused with a nuclear explosion, such as a fission bomb, which produces blast effects far in excess of what is achievable by the use of conventional explosives. Unlike the cloud of radiation from a typical fission bomb, a dirty bomb’s radiation can be dispersed only within a few hundred meters or a few miles of the explosion. Dirty bombs have never been used, only tested. They are designed to disperse radioactive material over a certain area. They act through the effects of radioactive contamination on the environment and related health effects of radiation poisoning in the affected populations. The containment and decontamination of ...

Rally For Democracy And Development
The Rally for Democracy and Development (''Rassemblement pour la Démocratie et le Développement''; RDD) is a political party in the Republic of the Congo. It has been one of the main participants in a coalition known as the African Socialist Movement-Congolese Progressive Party (MSA-PPC). History The RDD was founded in 1990 under the leadership of former Head of State Joachim Yhombi-Opango.''Political Parties of the World'' (6th edition, 2005), ed. Bogdan Szajkowski, page 140. In the June–July 1992 parliamentary election, the RDD won five seats in the National Assembly. Yhombi-Opango was the RDD's candidate in the August 1992 presidential election, placing sixth with 3.49% of the vote. In the June 1993 parliamentary election, the party won six seats in the National Assembly, and it was part of the governing coalition of President Pascal Lissouba, with Yhombi-Opango serving as Prime Minister from 1993 to 1996. The RDD was loyal to Lissouba during the 1997 civil war, and wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Random Digit Dialing
Random digit dialing (RDD) is a method for selecting people for involvement in telephone statistical surveys by generating telephone numbers at random. Random digit dialing has the advantage that it includes unlisted numbers that would be missed if the numbers were selected from a phone book. In populations where there is a high telephone-ownership rate, it can be a cost efficient way to get complete coverage of a geographic area. RDD is widely used for statistical surveys, including election opinion polling and selection of experimental control groups. When the desired coverage area matches up closely enough with country codes and area codes, random digits can be chosen within the desired area codes. In cases where the desired region doesn't match area codes (for instance, electoral districts), surveys must rely on telephone databases, and must rely on self-reported address information for unlisted numbers. Increasing use of mobile phones (although there are currently techniq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Redding Municipal Airport
Redding Regional Airport is 6 miles (10 km) southeast of Redding in Shasta County, California, United States. It is one of two airports in Redding, along with Benton Airpark. In addition to general aviation, the airport has scheduled passenger flights nonstop to and from Burbank (BUR) on Avelo Airlines Boeing 737s, Los Angeles (LAX) and San Francisco (SFO) on United Express Canadair CRJ200 and CRJ700 regional jets, and Alaska Airlines Embraer E175 service to Seattle (SEA). History The city wanted a new airport and put in for a Works Progress Administration project that was called the Stillwater Airfield. Before the airfield was built in 1942, the site was acquired by the United States Army Corps of Engineers for the United States Army Air Forces and built the Redding Army Airfield. Initially, this was a sub-base for Chico AAF and garrisoned by the 433d Army Air Force Base Unit. It was under IV Fighter Command at Hamiltion AAF. The mission of Redding Army Air Field ...

Regression Discontinuity Design
In statistics, econometrics, political science, epidemiology, and related disciplines, a regression discontinuity design (RDD) is a quasi-experimental pretest-posttest design that aims to determine the causal effects of interventions by assigning a cutoff or threshold above or below which an intervention is assigned. By comparing observations lying closely on either side of the threshold, it is possible to estimate the average treatment effect in environments in which randomisation is unfeasible. However, it remains impossible to make true causal inference with this method alone, as it does not automatically reject causal effects by any potential confounding variable. First applied by Donald Thistlethwaite and Donald Campbell (1960) to the evaluation of scholarship programs, the RDD has become increasingly popular in recent years. Recent study comparisons of randomised controlled trials (RCTs) and RDDs have empirically demonstrated the internal validity of the design. Example The ...

Clipper (programming Language)
Clipper is an xBase compiler that implements a variant of the ''xBase'' computer programming language. It is used to create or extend software programs that originally operated primarily under MS-DOS. Although it is a powerful general-purpose programming language, it was primarily used to create database/business programs. One major dBase feature not implemented in Clipper is the dot-prompt (. prompt) interactive command set, which was an important part of the original dBase implementation. Clipper, from Nantucket Corp and later Computer Associates, started out as a native code compiler for dBase III databases, and later evolved. History Clipper was created by Nantucket Corporation, a company that was started in 1984 by Barry ReBell (management) and Brian Russell (technical); Larry Heimendinger was Nantucket's president. In 1992, the company was sold to Computer Associates for 190 million dollars and the product was renamed to CA-Clipper. Clipper was created as a replace ...

Apache Spark
Apache Spark is an open-source unified analytics engine for large-scale data processing. Spark provides an interface for programming clusters with implicit data parallelism and fault tolerance. Originally developed at the University of California, Berkeley's AMPLab, the Spark codebase was later donated to the Apache Software Foundation, which has maintained it since. Overview Apache Spark has its architectural foundation in the resilient distributed dataset (RDD), a read-only multiset of data items distributed over a cluster of machines, that is maintained in a fault-tolerant way. The Dataframe API was released as an abstraction on top of the RDD, followed by the Dataset API. In Spark 1.x, the RDD was the primary application programming interface (API), but as of Spark 2.x use of the Dataset API is encouraged even though the RDD API is not deprecated. The RDD technology still underlies the Dataset API. Spark and its RDDs were developed in 2012 in response to limitations i ...

Responsibility-driven Design
Responsibility-driven design is a design technique in object-oriented programming, which improves encapsulation by using the client–server model. It focuses on the contract by considering the actions that the object is responsible for and the information that the object shares. It was proposed by Rebecca Wirfs-Brock and Brian Wilkerson. Responsibility-driven design is in direct contrast with data-driven design, which promotes defining the behavior of a class along with the data that it holds. Data-driven design is not the same as data-driven programming, which is concerned with using data to determine the control flow, not class design. In the client–server model they refer to, both the client and the server are classes or instances of classes. At any particular time, either the client or the server represents an object. Both the parties commit to a contract and exchange information by adhering to it. The client can only make the requests specified in the contract and the ...
