In this thesis we propose a way to analyze certain classes of dimension reduction models for elliptic problems in thin domains. We consider Poisson equations in thin rectangles and plates, and develop asymptotic expansions for the exact and model solutions , having the thickness as small parameter. The modeling error is then estimated by comparing the(More)
Effect of the substrate dilution on the room and high temperature tribological behaviour of Ni-based coatings deposited by PTA on grey cast iron, This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting,(More)
This work presents a brief description of the human auditory system together with the history of human comprehension of the auditory function, its main features, and classic models used to represent it. First, a historical view of the hearing apparatus is presented. After that, the physiology of the peripheral auditory system is described. The process of(More)
This paper presents a measurement-based comparison of cm-wave propagation in urban and suburban scenarios at 24 GHz with transmitter antennas located above rooftop level. Different sets of directional measurements, exploring the full azimuth and the range from -30 to +30 degrees in elevation, were performed with horn antennas located close to street level,(More)
A 3D Finite Element Monte Carlo simulation with 2D Schrödinger based quantum correction are employed to forecast the performance of SOI Si FinFET devices scaled to gate length of 10.7 nm. The performance of these devices are greatly affected by the exact device geometry and thus the accurate description of cross-sections is essential. We chose three(More)
