In this contribution, we present iHEARu-PLAY, an online, multi-player platform for crowdsourced database collection and labelling, including the voice analysis application (VoiLA), a free web-based speech classification tool designed to educate iHEARu-PLAY users about state-of-the-art speech analysis paradigms. Via this associated speech analysis web interface, in addition, VoiLA encourages users...
There are problems with insulation failures in high-voltage transformers due to fast transient voltages. Within novel Solid-State Transformers (SST) this problem exists constitutionally because of the SSTs rectangular working voltages. Experiments and simulations have been performed to get accurate understanding of the phenomena. The results and theories are discussed in this paper.
We introduce iHEARu-PLAY, a web-based multi-player game for crowdsourced database collection and — most important — labelling. Existing databases (with speech and video content) can be added to the game and labelling tasks can be defined via a web-interface. The primary purpose of iHEARu-PLAY is multi-label, holistic annotation of multi-modal affective speech databases. Players perform labelling (or...
This paper investigates the parasitic turn on during the reverse recovery of the body diode of the normally on 1200 V SiC JFET. During the reverse recovery flows a hole current through the space charge region. The hole current is increasing the charge in the space charge region and the gradient of electrical field increases. A higher gradient of electrical field with the same switching speed causes...
