Deep seabed polymetallic nodule mining machines have to operate in extremely soft ocean floor having soils of shear strength in the order of 1-3 kPa. The extent of sinkage and pullout force or breakout force required to lift the mining machine from the seafloor bottom needs to be evaluated for the successful operation and retrieval of the mining machine. In most of the cases the breakout force exceeds...
The stability testing of 2-Dimensional recursive digital filters had been a very hot problem in 1970's and 80's. The right solution is not yet available though some researchers have been working on this problem even now. We have proposed in this paper a test procedure to test the stability of 1-D recursive digital filters and quantization error estimation for the same filters. We also gave for a restricted...
In this paper, a three dimensional numerical model of a uniformly doped nanoscale MOSFET device considering the quantum-mechanical effects has been presented. The 3D Poissonpsilas equation in the space charge region coupled with 3D Schrodinger equation has been solved numerically using Leibmannpsilas iteration method. The exact potential profile and electric field profile were estimated from the set...
