The Dirichlet problem for Laplace's equation in an area between two arbitrary profiled infinitely long cylinders is rigorously solved by the Method of Regularization. The obtained solution is applied to the accurate analysis of the shielded microstrip line with homogeneous dielectric filling and thick conductor - the structure supporting the transmission of an ideal TEM-wave. Capacitance and characteristic...
Analytical expressions for electric potential and electric fringe fields in regions above the fingers of MEMS (microelectromechanical systems) comb capacitances are derived using potential-theoretic methods. The formulas are valid for the following: (1) a comb geometry exhibiting a large number of identical fingers and (2) a finger geometry where the gap between fingers is small compared to the height...
Image matting deals with finding the probability that each pixel in an image belongs to a user specified dasiaobjectpsila or to the remaining dasiabackgroundpsila. Most existing methods estimate the mattes for two groups only. Moreover, most of these methods estimate the mattes with a particular bias towards the object and hence the resulting mattes do not sum up to 1 across the different groups....
