This paper describes the assist force control of semi-active assist system ldquosmart suitrdquo for horse trainer. We developed a soft and flexible power assist device named ldquosmart suitrdquo for reducing horse trainers' physical fatigue in their horse training works in order to prevent their spine or legs injuries. The smart suit is a kind of semi-active and flexible power assist devices. In order...
The solutions to an optimal power allocation problem in dual-hop amplify-and-forward (non-regenerative) OFDM relay systems over given channel gains are provided with a joint transmit power constraint. We analytically derive the allocated power to each hop/subcarrier that satisfies the Karush-Kuhn-Tucker (KKT) conditions by solving simultaneous equations. The solutions imply that at most 3N - 1 possible...
This paper deals with a three-phase to single-phase power conversion system using a matrix converter topology. In order to compensate for instantaneous power unbalance occurring between three-phase circuits and single-phase circuits, a small reactor is installed into a matrix converter. The proposed circuit and control diagrams as well as some important simulation results are described herein.
We describe the design and the MPI-implementation of two parallel tree code molecular dynamics programs called MolTreC and Treecode AMBER, respectively. Both programs were developed using the parallel Barnes-Hut tree code for calculating Coulomb interactions which have been developed in earlier work. The parallel programs can rapidly calculate the Coulomb interactions of proteins in water without...
