We investigated effective features for human detection. The histogram of oriented gradients (HOG), which was proposed by N. Dalal, is an important representation that accumulates the edge-magnitude into a quantized histogram. Effective features similar to the HOG have been proposed. We question what the most effective feature is. We thus evaluate several features on three datasets of pedestrians,...
Superconducting fault current limiters (SFCLs) are expected to be installed in the power system for fault current limitation and improvement of power system stability. Among various SFCLs, we have proposed the transformer-type SFCL that produces limiting reactance for smaller fault currents and, additionally, gives limiting resistance for larger fault currents. Therefore, the transformer-type SFCL...
An effect of the time constant of the measurement setup on a breakdown behavior of SiC MOS capacitors with aluminum gate electrode was investigated. For this experiment, an additional series resistance was inserted into the TDDB and TZDB measurement system. With respect to TDDB, SBD occurred more frequently when the additional series resistance was inserted. It is speculated that the joule heat generated...
