Their common features are small-scale, distributed and independent operation. There are various other factors that can affect the economy or environmental impact of the existing power network. The objective of this research is to assess the technological impact of independent power producers introduced into an existing power system. The authors conducted the evaluation of the impact by multiple perspective. To assess the impact of IPPs, optimal power flow simulations have been repeatedly applied, changing the possible IPP locations.","PeriodicalId":359446,"journal":{"name":"CCECE '97.

The total channel bandwidth is generally divided between motion and residue information. The overall bit rate can be controlled by changing the quantization setting of the residue coder, but no simple control mechanism exists for the motion coder. This paper introduces a method of encoding motion vectors, which provides a simple mechanism of controlling the motion side information bit rate. By being able to control both the motion and residue information bit rates: the coder is capable of dividing the available bandwidth between the two channels in an optimal way. This results in a more efficient coding system.","PeriodicalId":359446,"journal":{"name":"CCECE '97. Canadian Conference on Electrical and Computer Engineering.

It maintains good performance in a Rician fading channel, and a RAKE receiver could be used to improve the performance in a Rayleigh fading channel. The improved power and bandwidth efficiency of CPSK makes it suitable for wireless local area network applications.","PeriodicalId":359446,"journal":{"name":"CCECE '97.

I share some of this excitement about the future, and am myself engaged with colleagues and students in engineering research designed to bring it about. But I note that large sums of money are being invested by companies and universities on the basis of rather simple assumptions about what is likely to happen. In this paper, I should like to turn aside from the detail of the technology and ask, as well as attempt to answer, two questions. The first is important though apparently rather academic, and the second more practical: I . Is it possible to say anything useful at all about the &ture of multimedia communication? 2. Given the answer to I , what strategy will lead to a maximum return on investment in this area? With regard to the second question, I should point out that we do not need to be business people to be concerned with optimizing investment; academics and other research workers invest time, energy and resources pursuing selected research goals according to their beliefs about the future.","PeriodicalId":359446,"journal":{"name":"CCECE '97.
