China Railways DFH Shunting Locomotives
The China Railways "Dongfang Hong" diesel-hydraulic locomotive classes DFH2, DFH5, DFH6, and DFH7, built from the 1970s to 1990s, were all used as shunters on the Chinese railway network. The use of diesel-hydraulic shunters has fallen out of favour on the Chinese rail network, with diesel-electric locomotives being used. However, diesel-hydraulic machines continued to be produced for industrial railways – mainly the China Railways GK classes.DFH5 东方红5 , ''www.railwaysofchina.com'' The DFH21 class is a meter gauge version of the DFH2, and was used on the Yunnan–Vietnam Railway for both passenger and freight services; the same machines are used on the Vietnam Railways where they are known as the D10H. China Railways standard gauge DFH2 The DFH2 was originally designed by Sifang locomotive w ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China Railways DFH Mainline Locomotives
The China Railways DFH1 () was a type of 4-axle B'B' single-cab diesel-hydraulic locomotive used on mainline passenger services; the DFH3 () was a later development of a similar design but with two driving cabs. The China Railways DFH4 () was a 6-axle high-powered freight and passenger locomotive, it did not reach mass production. China Railways DFH1 The first prototype unit (NY1) (''neiran yeli chuandong'' meaning diesel-hydraulic transmission) was produced in 1959 at Sifang locomotive works, and given the name 'Weixing'. Locomotive design was similar to German diesel-hydraulic machines such as the DB Class V 200 - the machine had a pair of high-speed diesel engines, each driving a separate hydraulic torque converter based transmission resulting in low mass compared to contemporary diesel-electric machines. Series production began in 1964. The locomotive was used for passenger trains. The locomotives could be worked in multiple, and were often used in this way, with a cab at ...

Discovery Fit And Health
Discovery Life is an American cable television network owned by Warner Bros. Discovery. Launched on February 1, 2011 as Discovery Fit & Health, it was the result of the merger of the Discovery Health Channel and FitTV, following the former's replacement in its channel space by the Oprah Winfrey Network. The channel primarily focuses on reality programming dealing with "life events". Its programming targets a female audience, and consists of reruns drawn from the libraries of its predecessors and TLC. , Discovery Life is available to approximately 24,000,000 pay television households in the United States-down from its 2017 peak of 47,000,000 households. Along with American Heroes Channel, Boomerang, Cooking Channel, Destination America, Discovery Family, and Science Channel, Discovery Life is among the less prevalent networks of Warner Bros. Discovery. In recent years, Discovery Life has lost carriage with the growth of streaming alternatives including its parent company's Max, ...

Dynamic Frequency Hopping
One of the key challenges of the cognitive radio based wireless networks, such as IEEE 802.22 wireless regional area networks (WRAN), is to address two apparently conflicting requirements: assuring Quality of Services (QoS) satisfaction for services provided by the cognitive radio networks, while providing reliable spectrum sensing for guaranteeing licensed user protection. To perform reliable sensing, in the basic operation mode on a single frequency band (the so-called "listenbefore-talk" mode) one has to allocate Quiet Times, in which no data transmission is permitted. Such periodic interruption of data transmission could impair the QoS of cognitive radio systems. This issue is addressed by an alternative operation mode proposed in IEEE 802.22 called Dynamic Frequency Hopping Frequency-hopping spread spectrum (FHSS) is a method of transmitting radio signals by rapidly changing the carrier frequency among many frequencies occupying a large spectral band. The changes are co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franco-German University
The Franco-German University (FGU, , ) is an international organisation of universities from Germany and France with the purpose of facilitating international cooperation in higher education. The FGU is not a university in its own right, but rather enables students to study at multiple universities in both countries in a Franco-German course of study, leading to a double degree. History and organisation In a first attempt at higher education cooperation, a ''Franco-German College for Higher Education'' (, ) had existed since 1988. That organisation had similar goals, working to promote international academic cooperation and student exchanges. At the September 1997 Franco-German Summit in Weimar, the French and German governments concluded the Weimar Agreement, deciding to establish the Franco-German University with the intention of international cooperation. The agreement came into effect two years later when the Franco-German University was formally founded. The organisat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
