Ultrathin (UTD) and Nanoscale (NSD) SOI-MOSFET devices, sharing a similar W/L but with a channel thickness of 46nm and 1.6nm respectively, were fabricated using a selective “gate recessed” process on the same silicon wafer. The electrical transport characterization at room temperature has shown a large difference between the two kinds of devices and has been interpreted in terms of a huge unexp...

In this paper, we propose a 3D model to characterize the field scattered by an urban area, which is composed of a group of buildings, for both monostatic and bistatic radar configurations. This model is based on a ray-tracing technique combined with the Uniform Theory of Diffraction (UTD). It is useful not only in elucidating mechanisms of ray propagation through the observed area, but also in ...

The balanced canonical form and parametrization of Ober for the case of SISO stable systems are extended to blockbalanced canonical forms and related input-normal forms and parametrizations. They form an overlapping atlas of parametrizations of the manifold of stable SISO systems of given order. This extends the usefullness of these parametrizations, e.g. in gradiënt algorithms for system ident...

Blood donation is someone who voluntarily gives blood; then, the feasibility processed and transfused to patients in need. donors come from voluntary blood or substitute donors/families certain communities. The COVID-19 pandemic spread of a coronavirus epidemic that has various continents countries. This research quantitative descriptive study with time approach used as retrospective. number do...

This paper presents two uniform theories of diffraction–physical optics (UTD-PO) formulations to undertake analysis radiowave multiple diffraction resulting from the presence both buildings and trees in vegetated urban areas, with assumption spherical-wave incidence. The solutions presented consider modeled as knife-edges rectangular sections (the latter being more complex realistic) effect tre...
