High Quality Content by WIKIPEDIA articles! Turtles are a class of educational robots designed originally in the late 1940s (largely under the auspices of researcher William Grey Walter) and used in computer science and mechanical engineering training. These devices are traditionally built low to the ground with a roughly hemispheric (sometimes transparent) shell and a power train capable of a very small turning radius. The robots are often equipped with sensor devices which aid in avoiding obstacles and, if the robot is sufficiently sophisticated, allow it some perception of its environment. Turtle robots are commercially available and are common projects for robotics hobbyists. Данное издание не является...

High Quality Content by WIKIPEDIA articles! TV DX and FM DX are two terms, customarily grouped together, that refer to long-distance reception of TV and FM radio stations, respectively. The term DX is an old telegraphic term meaning "long distance." These terms refer to the active search for distant radio or television stations received during unusual tropospheric lower atmospheric weather-related, or E-layer and F2-layer upper atmospheric ionospheric conditions. VHF/UHF television and radio signals are normally limited to a maximum "deep fringe" reception service area of approximately 40–100 miles (64–160 km) in areas where the broadcast spectrum is congested, and about 50 percent farther in the absence of interference. However,...

High Quality Content by WIKIPEDIA articles! The Tweel (a portmanteau of tire and wheel) is an experimental tire design developed by the French tire company Michelin. The tire uses no air, and therefore cannot burst or become flat. Instead, the Tweel's hub connects to flexible polyurethane spokes which are used to support an outer rim and assume the shock-absorbing role of a traditional tire's pneumatic properties. The Tweel consists of a cable-reinforced band of conventional tire rubber with molded tread, a shear band just below the tread that creates a compliant contact patch, and a series of energy-absorbing polyurethane spokes. The rectangular spokes can be designed to have a range of stiffnesses, so engineers can control how the...

Twin Coach was a company formed by the Fageol brothers when they left the Fageol Motor Company in 1927. They established the company in Kent, Ohio, to manufacture and sell buses with a new concept design. The body structure of this new bus was unique in that the body also became the frame and two engines were used to allow for larger passenger loads. This concept was patented by William B. Fageol. Over the years, Twin Coach made transit buses, trackless trolleys, small delivery vehicles, Fageol six-cylinder gasoline/propane bus and marine engines, Fageol four-cylinder Marine engines, and aircraft and truck components. The bus operations were sold to Flxible in the mid-1950s. A portion of the company called Highway Products produced a...

Pavement performance modeling is one of the key challenges facing pavement engineers and researchers. Although many new techniques have been applied to the pavement performance modeling, the accuracy of predictions still needs to be further improved. Two novel approaches were proposed in this work: a clusterwise least squares (CLS) regression method for pavement condition rating and a simplified mechanistic-empirical based probabilistic procedure for fatigue cracking of flexible pavements. In a CLS regression model, several clusters (curves), instead of only one as used in an ordinary least squares (OLS) regression model, are used to fit the modeling dataset. The results of the study show that the proposed model resulted in more accurate...

The performance of thermal devices such as evaporators is greatly affected due to flow mal- distribution in the parallel channels. There is inherent flow mal-distribution in manifolds involving single-phase flow which is a result of non- uniformity of the pressure drop across each lateral channel. This will even be more complicated when the flow involves two phase, which is often the case in refrigerant flow of multi-pass evaporators, since there is gravity induced preferential phase separation at the entrance to lateral channels in manifolds. In this book, the result of experimental and theoretical study of single-phase and two-phase flow mal-distribution performed on a model brazed aluminum evaporator having horizontal headers is...

The use of two phase closed thermosyphons has been on the rise in recent years. This is due to the fact that thermosyphons offer very low thermal resistance, are highly efficient and very easy to manufacture. Thermosyphons are especially suitable for applications where there is considerable distance between heat source and heat sink. One such application is in cooling the moderator of cold neutron source (CNS) of research nuclear reactors. However, the operational limit of the closed two phase thermosyphons has been the focus of very few studies. Most of these studies considered only the thermosyphon, but have not included the vapor reservoir. In this book, the fundamental working principles of Two-Phase Closed Thermosyphon with...

High Quality Content by WIKIPEDIA articles! A two-way radio is a radio that can both transmit and receive (a transceiver), unlike a broadcast receiver which only receives content. Two-way radios are available in mobile, stationary base and hand-held portable configurations. Hand-held radios are often called walkie-talkies or handie-talkies. A push-to-talk or Press To Transmit button is often present to activate the transmitter. A mobile phone or cellular telephone is an example of a two-way radio that both transmits and receives at the same time (or full-duplex). It uses two different radio frequencies to carry the two directions of the conversation simultaneously. Данное издание не является...

A two-port network is an electrical circuit or device with two pairs of terminals connected together internally by an electrical network. Two terminals constitute a port if they satisfy the essential requirement known as the port condition: the same current must enter and leave a port. Examples include small-signal models for transistors, filters and matching networks. The analysis of passive two-port networks is an outgrowth of reciprocity theorems first derived by Lorentz.

An extensive experimental two-phase flow study has been carried out on two single round microtubes for refrigerants. First of all, an optical measurement method for two-phase flow pattern characterization in microtubes was developed to determine the frequency of bubbles exiting a micro-evaporator, their coalescence rates and lengths as well as their mean two-phase vapor velocity. Based on the bubble frequency results and CHF (Critical Heat Flux) measurements made on the micro-evaporator (predicted with a new microchannel version of the Katto-Ohno correlation), a new type of flow pattern map for evaporating flow in microchannels was proposed. This flow pattern map may in the future be used as the starting point for the development of heat...

High Quality Content by WIKIPEDIA articles! In some networks, users are homogeneous, that is, they all perform similar functions. For example, although participants in a telephone network originate and receive calls, these roles are transient. Almost all phone users play both roles at different times. Likewise, almost all instant messaging, FAX, and email users both. Networks with homogenous users are called one-sided to distinguish them from two-sided networks, which have two distinct user groups whose respective members consistently play the same role in transactions. In a two-sided network, members of each group exhibit a preference regarding the number of users in the other group; these are called cross-side network effects. Each...

A two-stroke engine is a combustion engine that completes the thermodynamic cycle in two movements of the piston compared to twice that number for a four-stroke engine. This increased efficiency is accomplished by using the beginning of the compression stroke and the end of the combustion stroke to perform simultaneously the intake and exhaust (or scavenging) functions. In this way two-stroke engines often provide strikingly high specific power. Gasoline (spark ignition) versions are particularly useful in lightweight (portable) applications such as chainsaws and the concept is also used in diesel compression ignition engines in large and non-weight sensitive applications such as ships and locomotives. Invention of the two-stroke cycle...

High Quality Content by WIKIPEDIA articles! In cryptography, Twofish is a symmetric key block cipher with a block size of 128 bits and key sizes up to 256 bits. It was one of the five finalists of the Advanced Encryption Standard contest, but was not selected for standardisation. Twofish is related to the earlier block cipher Blowfish.Twofish's distinctive features are the use of pre-computed key-dependent S-boxes, and a relatively complex key schedule. One half of an n-bit key is used as the actual encryption key and the other half of the n-bit key is used to modify the encryption algorithm (key-dependent S-boxes). Twofish borrows some elements from other designs; for example, the pseudo-Hadamard transform (PHT) from the SAFER family of...

The Type 61 was a main battle tank (MBT) developed and used by the Japan Ground Self-Defense Force (JGSDF), built by Mitsubishi Heavy Industries. Development started in 1955 and the vehicle was first deployed in April 1961. The type number follows the year of deployment. A total of 560 Type 61's were manufactured between 1961 to 1975, when production ceased. After World War II, Supreme Commander of the Allied Powers (A.K.A. GHQ in Japan) ceased all military manufacturing and development plants in Japan, making Japan lose the technology to build and manufacture tanks and armoured vehicles (even though the technology was not well developed.) However, due to the Korean War, the Supreme Commander of the Allied Powers ordered Japan to...

The Type 59 (Chinese industrial designation: WZ120) Main Battle Tank is a Chinese produced version of the Soviet T-54A tank, an improvement over the ubiquitous T-54/55. The first vehicles were produced in 1958 and it was accepted into service in 1959, with serial production beginning in 1963. Approximately 9,500 of the tanks were produced by the time production ended in 1980 with approximately 5,500 serving with the Chinese armed forces. The tank formed the backbone of the Chinese People's Liberation Army until early 2000s with an estimated 5,000 of the later Type 59-I and Type 59-II variants in service in 2002.

The Type 96 is the latest variant of China's third-generation main battle tank (MBT). Based on the Type 85-III design, the Type 96 entered service with the People's Liberation Army (PLA) in 1997. As of 2005, an estimated 1,500 Type 96 tanks are currently in service with the PLA.Generally speaking, PLA's tank development can be divided into three generations. The first generation is a version of the Soviet T-54A and its derivatives, produced in China as the Type 59 and Type 69/79. The second-generation main battle tank started with the Type 80, which further branched into the Type 88 and Type 96, developed in parallel by different institutes but all funded by China North Industries Corporation (NORINCO). The Third-generation started with...

The Type 69 and Type 79 are two models of Chinese main battle tanks. Both developments of the Type 59 (based on the Soviet T-54A), they were the first independently-developed main battle tanks by China. Their lineage can be seen through the distinct gap between the first and second roadwheels. Other improvements included a new engine, ballistic computers, and laser rangefinders. The more advanced Type 79 was equipped with a 105 mm rifled gun, also seen on the later Type 88 tank.After the Sino-Soviet split, the Soviet Union withdrew its technical staff and support to China's arms industry. China's 617 Factory (Inner-Mongolia First Machine Group Co Ltd) was tasked to improve on the T-54A design (Type 59 MBT) in 1963, which became the Type...
