In electric vehicles, currents with high-frequency ripples flow in the power cabling system due to switching operation of converters. Inside cables, a strong coupling between thermal and electromagnetic phenomena exists, since temperature Alternating Current (AC) density distributions strands affect each other. Due different time scales magnetic heat problems, computational cost Finite Element ...

This paper presents an indirect method for computing optimal trajectory, subject to robot dynamics, exibilities and actuator constraints. One key-issue that arises from mechanism exibility is nding the Dynamic Load Carrying Capacity (DLCC). The motion planning problem is rst formulated as an optimization problem, and then solved using Pontryagin's minimum principle. The basic problem is convert...

Cryogenics (2009), doi:10.1016 Performance degradation of Nb3Sn cable-in-conduit conductors (CICCs) is a critical issue in large-scale magnet design such as the International Thermonuclear Experimental Reactor (ITER) and the seriesconnected hybrid (SCH) magnets currently under development at the National High Magnetic Field ...

Abstract High-temperature superconductor (Re)Ba 2 Cu 3 O x (ReBCO) conductor on round core cable (CORC ® ) has a large current carrying capacity for high field magnets. Lorentz forces acting CORC conductors, cause reduction of the critical current, or even permanent degradation their performance when exceeding values. Transverse compressive stress is one principal mechanical stresses cables are...

UNLABELLED Cable bacteria are filamentous bacteria that electrically couple sulfide oxidation and oxygen reduction at centimeter distances, and observations in sediment environments have suggested that they are motile. By time-lapse microscopy, we found that cable bacteria used gliding motility on surfaces with a highly variable speed of 0.5 ± 0.3 μm s(-1) (mean ± standard deviation) and time b...

Power cable is a piece of major transmission equipment, and its operating temperature as factor determines whether the system can operate safely reliably current-carrying capacity. Therefore, it great significance to master real-time distribution power core. During aging insulation, temperature, factor, directly rate. One basic parameters on ampacity. If ampacity high, will be overloaded. In th...

Cable-supported bridges rely on the use of steel cables to support the bridge deck and load on it. Cable tension forces are monitored during construction to assist the alignment of cables and to ensure no cables are overloaded. Given that the cables are critical load carrying elements, it is prudent to routinely monitor the levels of cable tensions during operation. With current measurement met...
