Abstract: A system and method for frequency planning in a wireless communication network area using an impact matrix which relates signal interference impacts between sectors in a network service area for co-channel and adjacent channel interference. The impact matrix uses weighted propagation analysis and empirical measurement data to determine signal levels within each pixel of a network service area. The system merges the propagation analysis and empirical measurement data according to user assigned confidences.

Abstract: A handwritten pattern and stroke recognition system recognizes an input pattern by comparing it to reference patterns. The input and reference patterns comprise at least one stroke, where a stroke is defined as the series of sample points from pen-down to pen-up. The system of the present invention compares the input and reference patterns stroke by stroke and thus, compares input strokes to reference strokes. The system includes a tangent and stable point extractor, a reference database and a stable-point-based classifier. The extracter determines tangents to at least some of the sample points of the input stroke and determines, which of the sample points between a beginning and end of the input stroke are stable points. The reference database stores tangents of sample points of the reference strokes and stable points of the reference strokes.

Abstract: A method for determining a stowage plan is proposed which utilizes "genetic" or "evolutionary" search techniques. The method includes the steps of generating a multiplicity of "genotypes", each of which corresponds to one possible stowage plan. Each stowage plan is then evaluated in terms of the cost of implementing it. The cost is at least a function of the weight distribution of the vessel and the number of restows required. The initial genotypes and the cost function for evaluating them are provided to the genetic algorithm which operates to reduce the cost to one below a predefined threshold.
