A high sensitive CMOS Micro-electro-mechanical rectangular capacitive pressure sensor in SiGeMEMS process (Silicon Germanium Micro-electro-mechanical System process) is designed and analyzed. Polycrystalline Silicon Germanium (Poly-SiGe) having low fatigue and high strength is effectively used as the sensor diaphragm material to achieve better reliability. The designed perforated diaphragm clam...

We compute the non-linearity of Boolean functions with Gröbner basis techniques. Moreover, we extend our approach to classify functions with maximum non-linearity.

Introduction of new communication standards makes specifications given to RF surface and bulk acoustic wave (SAW/BAW) devices tougher and tougher. For example, futher improvement of the device linearity is demanded without increasing the device size. Nevertheless, it is still unclear where and how the non-linearity occurs. For finding origin(s) of the very weak non-linearity, its measurement sy...

"A main topic of this study is the non-linearity between sulfur dioxide emissions and sulfate mixing-ratios at surface and in the free troposphere. This aspect needs a more thorough analyses. Non-linearity is caused by low oxidant concentrations (OH and H2O2) in winter and by H2O2 limitations in regions with high SO2 emissions. As oxidation rate is the key process controlling the non-linearity,...

In this paper, a systematic procedure for synthesizing two-terminal devices with polynomial non-linearity is proposed. A two-terminal, or one-port, device with an arbitrary polynomial non-linearity can be designed using the proposed procedure in a step-by-step systematic manner. A variety of drivingpoint characteristics of two-terminal devices with synthesized polynomial non-linearity, both num...

The main objective of this study is to develop a computational approach based on the finite element (FE) method efficiently predict welding deformations and residual stresses fillet welded T-joints made high strength steel (HSS), S700, using different sequences external constraints. With aim, thermo-elastic-plastic FE models were developed in ABAQUS code Goldak's double ellipsoidal heat source ...

We study the effect of particle cohesion on the steady state shear strength of a granular material. For cohesive powders, the steady state shear loci (termination loci) from DEM simulations are nonlinear with a peculiar pressure dependence due to the non-linear increase of contact adhesion with pressure in the contact model. Physical experiments are carried out on fine limestone powder in the d...
