1. On Reliability of SiC Power Devices in Power Electronics
Abstract : Silicon Carbide (SiC) is a wide-bandgap (WBG) semiconductor materialwhich has several advantages such as higher maximum electric field, lowerON-state resistance, higher switching speeds, and higher maximum allowablejunction operation temperature compared to Silicon (Si). In the 1.2 kV - 1. READ MORE

2. Track circuits’ robustness : Modeling, measurement and simulation
Abstract : In countries with rough weather conditions, frequent delays cause railway companies to waste time and money. Many of these delays are related to the train detection systems, as the old DC track circuits are still used in some countries, including Sweden, our case study. READ MORE

4. Experimental Validation and Applications of a Phased Array Ultrasonic Testing Probe Model
Abstract : New manufacturing technologies are developed to facilitate flexible product designs and production processes. However, the quality of the final products should not be compromised. The assessment of product quality and integrity lies on various inspection methods. READ MORE

5. Estimation of the reliability of systems described by the Daniels Load-Sharing Model
Abstract : We consider the problem of estimating the failure stresses of bundles (i.e. the tensile forces that destroy the bundles), constructed of several statisti-cally similar fibres, given a particular kind of censored data. READ MORE
