Summary Understanding people behavior and movement characteristics during building evacuation is valuable in evaluating building designs and the effectiveness of evacuation policies. Simulation can be a powerful tool since real data on building evacuation are rarely available and costly to obtain. On the other hand, state-of-the-art in evacuation modeling is the use of agent-based simulations, which...
We present a new image reconstruction method for Electrical Capacitance Tomography (ECT). ECT image reconstruction is generally ill-posed because the number of measurements is small whereas the image dimensions are large. Here, we present a sparsity-inspired approach to achieve better ECT image reconstruction from the small number of measurements. Our approach for ECT image reconstruction is based...
We present a new image reconstruction method for Electrical Capacitance Tomography (ECT) by exploiting the sparsity of reconstructed images. ECT image reconstruction is generally ill-posed because the number of measurements is small whereas the image dimensions are large. Inspired by recent developments in Compressive Sensing (CS), given the sparsity of the signal (image), our idea is to apply an...

This paper presents a comprehensive study on the wire bond life for Insulated Gate Bipolar Transistors (IGBT). The main elements are as follows: 1) Substantial non-uniformity in temperature distribution across the chip area was revealed; 2) Additional electrical resistance at the wire bonds was discovered, which can elevate the local temperature and shorten the wire bond life; 3) Thermo-structural...
