A novel approach for the time-resolved analysis of high-speed sequences of particle images is presented. The proposed method aims at the minimization of PIV errors in the lower velocity range by adjusting locally and dynamically the interframe time interval of the PIV pairs in a recorded high-speed sequence. The algorithm performs the operation on a local(More)
In this work we compute the effective thermal conductivity of porous Si by means of the phonon Boltz-mann transport equation. Simulations of heat transport across aligned square pores reveal that the thermal conductivity can be decreased either by increasing the pore size or decreasing the pore spacing. Furthermore, by including the surface specularity(More)
In this work we present a multiscale method to model self-heating effects in nanostructured devices. While the heating is modeled within the drift-diffusion approximation, the heat dissipation is computed by means of a concurrent coupling between a Phonon Boltzmann Transport Equation (PBTE) based method and the Fourier model. We develop the way to connect(More)
Due to the downscaling of semiconductor device dimensions and the emergence of new devices based on nanostructures, CNTs and molecules, the classical device simulation approach based on semi-classical transport theories needs to be extended towards a quantum mechanical description. We present a simulation environment designed for multiscale and multiphysics(More)
y Deceased 2 Recent results from the CERN Omega spectrometer on the enhancement of strange and multiply strange particle production in nucleus-nucleus with respect to proton-nucleus collisions are summarized. In particular, the new data from the WA97 experiment on , and production in Pb{Pb and p{Pb collisions are presented and discussed.
We develop a computational framework, based on the Boltzmann transport equation (BTE), with the ability to compute thermal transport in nanostructured materials of any geometry using, as the only input, the bulk cumulative thermal conductivity. The main advantage of our method is twofold. First, while the scattering times and dispersion curves are unknown(More)
