We proposed a new class of asymmetric turbo encoder for 3G systems that performs well in both “water fall” and “error floor” regions in [7]. In this paper, a modified (optimal) power allocation scheme for the different bits of new class of asymmetric turbo encoder has been investigated to enhance the performance. The simulation results and performance bound for proposed asymmetric turbo code wi...

A novel asymmetric MOSFET with no LDD on the source side is simulated on bulk-Si using a device simulator (SILVACO). In order to overcome the problems of the conventional asymmetric process, a novel asymmetric MOSFET using mesa structure and sidewall spacer gate is proposed which provides self-alignment process, aggressive scaling, and uniformity. First of all, we have simulated to compare the ...

The present study deals with the flow and heat transfer analysis of two immiscible fluids in an inclined channel embedded in a porous medium. The channel is divided in two phases such that a third grade fluid occupies the phase I and a viscous fluid occupies the phase II. Both viscous and third grade fluids are electrically conducting. A constant magnetic field is imposed perpendicular to the c...

Rapid industrialization tends to occur at the expense of natural resources. Thus, countries are inclined control resources for their development objectives, which may create conflicts when allocate scarce national defense. As a major military block, NATO poses potential threat environmental degradation, as it comprises large industrialized arms manufacturers and spenders. Therefore, aim this st...

In this paper aims, we found the fluid concentration after calculating velocity and temperature of with a variable viscosity that depends on moving through an inclined porous channel. We examined influences certain parameters are active by analyzing graphs obtained reached momentum equation solution, used MATHEMATICA program for plot two types flow (Poiseuille Couette).

In view of the complex asymmetric deformation characteristics inclined coal seam roadways and tensed shear failure anchor cable supports, support scheme an with a C-shaped tube is proposed. order to study its supporting effect on roadway, this paper first explores difference in performance between through double tests. Then, based roadway Pangpangta Mine, numerical simulation used roadway. The ...

An experimental investigation with dry granular flows passing over an obstacle down a rough inclined channel has been performed. The aim is to improve our understanding of the interaction between dense snow avalanches and defence structures. Specific attention was directed to the study of the zone of influence upstream from the obstacle, linked to the formation of a dead zone. The dead zone len...
