Existing mechanical HVDC breakers are capable of interrupting HVDC currents within several tens of milliseconds, but this is too slow to fulfill the requirements of a reliable HVDC grid. HVDC breakers based on semiconductors can easily overcome the limitations of operating speed, but generate large transfer losses, typically in the range of 30 percent of the losses of a voltage source converter...

Issues of transfer and of human-computer systems are central, but largely separate questions in cognitive science. We take the human-computer system as the unit of analysis and explore how well a human-computer system transfers to tasks outside the scope of the humans’ training and the software’s design. In two experiments, participants used the procedure automation software (PRIDE) to control ...

Wireless Sensor Networks consists of no. of micro sensor nodes to monitor a remote environment by using aggregated data from individual nodes and transfer this data to the base station for further purpose. Here the energy of operated nodes is susceptible store of the Wireless Sensor Network, which is useless at a rate when information is transmitted, because transmission energy is reliant on th...

Walking time prediction aims to deduce waiting time and travel time for passengers and provide a quantitative basis for the subway schedule management. This model is founded based on transfer passenger flow and type of pedestrian facilities. Chaoyangmen station in Beijing was taken as the learning set to obtain the relationship between transfer walking speed and passenger volume. The sectional ...

Body Area Networks (BANs) are gaining prominence for their capability to revolutionize medical monitoring, diagnosis and treatment. This thesis describes a BAN that uses conductive fabrics (e-textiles) worn by the user to act as a power distribution and data communication network to sensors on the user’s body. The network is controlled by a central hub in the form of a Base Station, which can e...

A novel blind deconvolution methodology for identification of the local site characteristics based on two seismograms recorded on the free surface of a sediment site is presented. The approach does not require recordings at depth nor at a nearby rock outcrop, and eliminates the need for any prior parameterization of source and site characteristics. It considers that the surface recordings are t...

Base transceiver systems transfer large amounts of sampled baseband signals over serial data links between base station processors and RF modules. To comply with evolving wireless communication standards, greater data rates on these serial links are needed. However, increasing the actual bit rate on the links or increasing the number of physical links is in conflict with the existing base trans...

A design has been developed for a rotary fluid coupling to transfer coolant fluids (primarily anhydrous ammonia) across rotating joints of the Space Station. Development testing using three conceptual designs yielded data which were used to establish the design of a multipass fluid coupling capable of handling three fluid circuits. In addition, a mechanism to support the fluid coupling and allo...

Based on the analysis of work Khazarbagh irrigation system, water use plans, household regime Tupolang River, operation mode pumping station–I, proposals have been developed for partial transfer machine lands to gravity zone, Bandyhan–I subcommand station. With a two–fold accumulation in reservoir up 40-60 million m 3 and this compensation through end part Khazarbag canal, distributor P – I Ban...

Based on the marshalling station transfer operation process, this paper divides process into three sub-processes: arriving-disintegrating, disintegrating-marshalling and marshalling-dispatching. Considering input of facilities station, intermediate output operating time final number trains, an evaluation index system is constructed a slacks-based network DEA model established. For purposes illu...
