The Internal Field in Semiconductors,. The .., .. are the acceptor and donor impurity concentrations respectively and are independent of . and . Let this semiconductor be connected to an external potential .(.) with .(0) = .. and .(.) = 0. Then, if the semiconductor has sufficiently large dimensions in .- and .-directions, all physical

Some Least Squares Problems,.], [.]. In mass production machines are producing parts, and it is important to know, if the output satisfies the quality requirements. Therefore some sample parts are usually taken out of the production line, measured carefully and compared with the nominal features. If they do not fit the specifi

Smoothing Filters, smoothing filter to the measured data in order to reconstruct the underlying smooth function. We may assume that the noise is independent of the observed variable. Furthermore we assume that the noise obeys a normal distribution with mean zero and standard deviation δ.

Conformal Mapping of a Circle,r shape. Since the advent of supercomputers such techniques have become quite important in the context of numerical grid generation [.] . In introductory courses in fluid dynamics students learn how to calculate the circulation of an incompressible potential flow about a so-called “Joukowski airfoil

Heat Flow Problems,important equation describing heat flow rules , is the heat equation (Fourier equation).The difficulty of the solution of the Equation (14.1) depends on the difficulty of the boundary and initial conditions. We can distinguish two main groups of heat flow problems.

Modeling Penetration Phenomena,e protection of spacecraft or satellites from debris and/or meteorite impact. Formally the penetration is defined as the entrance of a projectile into the target without completing its passage through the body. The penetration phenomenon can be characterized according to the impact angle, the geomet
