Although IGBT turn on losses can be comparable to turn off losses, IGBT turn on has not been as thoroughly studied in the literature. Under clamped inductive load condition at turn on there is strong interaction between the IGBT and the freewheeling diode undergoing reverse recovery. A physics-based IGBT model is used that has been proved accurate in the simulation of IGBT turn off. Both resist...

Physics-based modeling of sound sources, such as of musical instruments and speech production, is based on several different modeling paradigms or methodologies. These can be roughly categorized as finite difference schemes, mass-spring models, modal decomposition methods, digital waveguide models, wave digital filter models, and source-filter models. The three first methods are based on the us...

Designing novel cyber-physical systems entails significant, costly physical experimentation. Simulation tools can enable the virtualization of experiments. Unfortunately, current tools have shortcomings that limit their utility for virtual experimentation. Language research can be especially helpful in addressing many of these problems. As a first step in this direction, we consider the questio...

This paper presents a physical model for planar spiral inductors on silicon, which accounts for eddy current effect in the conductor, crossover capacitance between the spiral and center-tap, capacitance between the spiral and substrate, substrate ohmic loss, and substrate capacitance. The model has been confirmed with measured results of inductors having a wide range of layout and process param...

Despite the fact that the database community has proposed a vast number of indexing methods over the years, no standard physical data model has been established like it has been achieved on the conceptual and logical level. How to optimize a given data model by using various indexing methods is still the ‚trade secret‘ of the database administrators. Only recently, some approaches have been tri...

Cyber-physical systems (CPS) in automotive or robotics industry comprise many different specific features, e.g., trajectory planning, lane correction, battery management or engine control, requiring a steady interaction with their environment over sensors and actuators. Assembling all these different features is one of the key challenges in the development of such complex systems. Component and...

Physical modeling is a proven technique for creating sounds with rich expressive potential, but the state of the art in control does not offer access to the whole of this potential. New developments in modeling algorithms are typically presented with single-point, idealized excitations where more complex ones would add vitality to the sounds produced. The 2D waveguide mesh, in particular, can b...

background and aims: the aim of this study was the modeling of the incidence rates of colorectal, breast and prostate cancers using a shared component model in order to explore the spatial pattern of their shared risk factors (i.e., obesity and low physical activity) affecting on cancer incidence, and also to estimate the relative weight of these shared components. methods: in this study, the ...
