Design of High-Density Filter Building Blocks for SiC-based Three-Phase Power Converters
… has resulted in a paradigm shift toward high-density and high-efficiency integration of power electronics systems. This being the result of relatively high switching frequencies (>10 kHz) compared to conventional Si IGBT counterparts, which reportedly can minimize the size of passive …

A COMPARISON OF THE PROBABILITY HYPOTHESIS DENSITY FILTER AND THE MULTIPLE HYPOTHESIS TRACKER FOR TRACKING TARGETS OF MULTIPLE TYPES
… and track objects of importance. The Bayes filter is the ideal algorithm for tracking a single target and there exists a significant body of work detailing tractable approximations of it with the notable examples of the Kalman and Extended Kalman filter. Multiple target tracking also relies …

Photoreflectance and Its Application to Semiconductor Characterization
… servomechanism to drive a variable neutral density filter for signal normalization. System performance under different conditions has been investigated. The methods to suppress the noise in the measurement are examined. The prototype system has been successfully applied to the …

Advances in the Use of Finite-Set Statistics for Multitarget Tracking
… algorithm known as the probability hypothesis density filter. Moreover, we develop a novel method for associating measurements to targets using the Bayes factor, which improves tracking performance for FISST methods as well as other approaches to multitarget tracking. Further, we derive a novel …

Analysis of target genes of the transcription factor CREM during mouse spermatogenesis
… of these clones was studied by the high-density filter hybridisation with total testicular cDNA. Most of these clones were shown to be expressed in wild type but down regulated in knockout. The spermatogenic stage specific expression profiles were determined by the hybridisation with the …

Developments in topology and shape optimization
… instability. Motivated by the success of filtering techniques that impose minimum length scales in topology optimization, we introduce a consistent filtering scheme to provide length scale control and thereby ensure smoothness in shape optimization while preserving the advantages of the …

Uv-Visible Microscope Spectrophotometric Polarization And Dichroism With Increased Discrimination Power In Forensic Analysis
… of microscope slides containing neutral density filter reference materials, molecular fluorescence reference materials, and dichroic reference materials. Upon completion of these standard slide preparations analysis began with measurements in order to evaluate figures of merit for …

System Reliability-Based Design and Multiresolution Topology Optimization
… distinct resolution levels to displacement, density and design variable fields: the finite element analysis is performed on a relatively coarse mesh; the optimization is performed on a moderately fine mesh for design variables; and the density is defined on a relatively fine mesh for material …
