This paper presents a systematic method of reducing clutter signals so as to enable detection of targets travelling at speeds near the Bragg Doppler. The algorithm uses a Hankel rank reduction method that assumes that targets and ocean clutter can be modelled as time varying sinusoids. Several examples of clutter suppression are shown from data that was collected at the Cape Race facility. A cooperating vessel was used to show that a clutter supression algorithm may be used to enhance target detection when the target's speed is near the Bragg Doppler frequency.","PeriodicalId":359446,"journal":{"name":"CCECE '97.

A parallel realization structure consisting of a number of 1-D FIR filters is obtained by applying the SVD to the impulse response of a 2-D filter. By using the symmetry property of the 2-D impulse response and by developing an appropriate unitary transform, a singular-value decomposition with symmetric and skew-symmetric singular vectors is obtained so that the constituent 1-D filters have linear-phase characteristics. It is shown that the number of parallel sections can be reduced significantly by neglecting the smaller singular values without introducing a large error in the magnitude response of the simplified 2-D filter.","PeriodicalId":359446,"journal":{"name":"CCECE '97.

As research matures to implementation stages, approaches to meter the actual power consumption in real-time are required. In this work, the authors model a real-time reactive power metering approach based on neural networks. A spot pricing model which incorporates the shortcomings of power factor penalties is used to determine the reactive power rates at each bus. A carefully designed artificial neural network (ANN) is trained to recognize the complex optimal operating point of an all-thermal electricity generating utility. A real time rate is allocated to each bus for a given power system's loading pattern and the recall process is instantaneous. The proposed approach is tested using a spot pricing model on 5 and 14 bus electric power systems. Different loading levels are used at each bus.","PeriodicalId":359446,"journal":{"name":"CCECE '97.

First the authors input a side view of a human head within a dark background under uniform lighting conditions by a CCD camera, then transform the input to a color difference signal image. After enhancing edges of the image using Sobel operators they binarize the luminance level of each pixel and portray a black profile in a white background. Next they differentiate the black profile, binarize the differentiated results, and depict a contour line using a thinning operator. Finally they encode the extracted contour line using Freeman's chain code and, using the encoded data, calculate the digital curvature in concave sections of the contour line and determine the concave feature points. Next they draw straight lines connecting the adjacent feature points and specify the convex feature points on the contour line which are farthest from the straight lines. They can obtain feature points of the profile automatically and reliably.","PeriodicalId":359446,"journal":{"name":"CCECE '97. Canadian Conference on Electrical and Computer Engineering.

An equivalent linear controller is used to identify the equivalent fuzzy PID tuning parameters related to each structure thus enabling the use of conventional PID tuning heuristics.","PeriodicalId":359446,"journal":{"name":"CCECE '97.

The SCP is the core physical entity of the IN architecture and is dedicated to process IN calls under stringent real-time requirements. We show, by means of simulations, that with the increasing complexity and amount of IN services stored in local disk-based databases, a variety of parameters and resources result in poor performance. The complexity of a service is described as the amount of service processing logic data required to complete an IN call. We also present some possible solutions in order to alleviate the poor performance when local disk-based databases are used.","PeriodicalId":359446,"journal":{"name":"CCECE '97.
