Power system operators should be trained to restore their system from a total or a partial blackout condition in a relatively short period of time. A case-based reasoning approach has been utilized to develop a training simulator for the SaskPower network. System operators can use the simulator in an interactive manner to simulate a restoration process. The simulator can guide system operators through the steps of a restoration process and displays the outcome(s) of a restoration action in terms of system states. The interaction between the simulator and an operator has been achieved through an object-oriented graphical interface.","PeriodicalId":177613,"journal":{"name":"Conference Proceedings.

In the coding system, the facial area, which is a moving object in the image sequence, is extracted from both the sending and receiving side without any control information. The candidate areas of the person are segmented using color information and the moving areas. The color information, which represent skin color, is extracted with a modified HSV color system. The moving areas are estimated using the motion parameters of objects, which are utilized for constructing the previous frame. The face is then extracted by merging the candidate areas based on the hue element of the modified HSV color system. The standard \"Claire\" video is used for the computer simulation, and facial areas are accurately extracted in all frames. Furthermore, to improve the subjective evaluation, the eyes and mouth are extracted as the most important areas in the face and coded precisely.","PeriodicalId":177613,"journal":{"name":"Conference Proceedings.

At 1.2 V and output loads of 0.1 to 0.7 pF the new logic style has up to 2.9 times better power efficiency than previously reported low-voltage BiCMOS styles and uses between 16 to 32 % less switching power. Under optimal conditions (V/sub dd/=1.6 V), the new design has up to 18% higher power efficiency than conventional CMOS logic for loads of 0.55 to 1 pF and up to 117 % better power efficiency compared to BiCMOS styles for output loads of 0.1 to 0.68 pF. When used to implement a full adder, it is more power-efficient at very low power supply voltages (1.1 to 2 V) than a conventional CMOS adder design and the best low-voltage low-power adder reported in the literature. The proposed BiDPL adder outperforms in power efficiency both designs at 1.5 V by as much as 61 % and 535 % respectively.","PeriodicalId":177613,"journal":{"name":"Conference Proceedings.

One significant feature of a RAN is its ability to allocate resources corresponding to the complexity of nonstationary signals, thus tracking and matching the complexity of nonstationary signals can be achieved. The experimental results of predicting chaotic time series and short-term power load have shown RAN is suitable for modelling and predicting such nonstationary signals with the fundamental advantage of complexity matching and tracking capability.","PeriodicalId":177613,"journal":{"name":"Conference Proceedings.
