Edge detection can be divided into two phases; the first is noise removal, and the second is ideal edge detection. By using an iterative averaged closing-opening operation, impulse noise as well as Gaussian noise is eliminated from the image. Then, the resulting ideal edges can be extracted, either by using one of the classical spatial operators or by a simple morphologic operator. Results obtained from test images show that the proposed morphologic edge detectors are very effective.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.

Specifically, both state and control variables are approximated by the B-spline function. A set of dynamic equations are derived through collocation. These approximations are further used to reduce the performance index containing function of both the state and control to a scalar function of B-spline coefficients. Thus, a dynamic optimization problem is thereby reduced to a simple, static optimization problem. Using a gradient-based algorithm, a set of minimum-fuel trajectories is obtained. Simulation results are included to demonstrate the applicability of the algorithm.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.

Results of several case studies are used to evaluate the effects of untransposed lines and unbalanced single-phase loads in the presence of grounded and ungrounded generator neutrals. Although line unbalance is shown to have only a minimal effect on generator transient response, the type of shunt fault does not make a significant difference. In particular, under certain network conditions the single-line-to-ground fault followed by temporarily switching out the faulted phase has a more severe effect on system stability than the traditionally accepted three-phase fault.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.

Linear programming automatically rejects bad measurements and provides an excellent set of bus voltages and angles which can be used as initial values in a weighted least-squares algorithm if filtering of Gaussian noise is desired. The performance of the linear program in the presence of multiple bad measurements is shown to be superior to the weighted-least-squares technique. The efficiency of the method is independent of the number of bad measurements and the magnitude of the error.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.
