Описание:The delay in construction of new generation- transmission systems due to various causes forces the power utilities to operate the existing facilities closer to their designed limits. A new approach has been adopted to extract off-line knowledge of a power system. This work would be helpful to the researchers in the area of power system analysis and control, and also to the operating personnel in a power system control center. This knowledge is then expressed in terms of rules. It, however, requires new tools and techniques to enhance the security of a power system. These rules constitute the symbolic logic part of the hybrid expert system. This makes the system vulnerable to electrical disturbances. Therefore, greater attention should be paid to keep the system always in a secured state. This book provides new load flow models for security analysis and also hybrid expert system for security control. In an on-line environment the hybrid expert system receives on-line data and after few calculations and comparisons with stored data suggests the appropriate control actions required to alleviate violations and thus ensures security of the system.

You can also hwclock to set the Linux system date and time date, using your hardware clock's values with the Linux system date and time. For example, to set the system time from your PC's hardware clock, use the --hctosys option as follows: # hwclock --hctosys Capturing Screen Images Although you're working at the command line rather than a swish GUI, you can still grab images from your graphical desktop through the import command, and that's exactly what we did to capture the images for this book. First, we ran xhost + on the remote computer to allow another computer access to the X server on the remote machine; the command to take the screenshot is run on our local machine like this: $ import -window root -display 12fig07.jpg This utility made a difficult task easy because the publisher required the screenshots be done from an 800Г—600 screen (too small to comfortably work in) to accommodate its printing and production equipment. We could also have used the classic UNIX tool xwd to take screenshots ...»

Mesospheric Temperature and Ozone Sounding Based on Solar Occultation Data. Retrieval Processing System and Performance Analysis
The solar intensity in the ultraviolet wavelength region is monitored by a satellite tracking the Sun in limb geometry during occultation by the Earth' s atmosphere. A processing system is presented and used to calculate atmospheric profiles from the solar radiation. This includes a mathematical description of the measurement and retrieval. The author Christoph Rehrl presents an end-to-end retrieval performance analysis for the developed retrieval processing system which was found to produce data with high vertical resolution and accuracy. This work provides a comprehensive insight in the present status as well as future developments in the field of solar occultations for probing atmosphere and climate. The understanding of physical and chemical processes of the Earth atmosphere is of crucial importance to daily life and to future conditions of this planet. This work develops and demonstrates the performance of a realistic forward model and retrieval algorithm for mesospheric temperature and ozone sounding employing the solar occultation technique. Observations of atmospheric parameters with high quality and long-term stability are essential for climate system monitoring.

Controlling of Large-Scale Systems with Special Regard to The Control of a Heat Power Station Soft Computing Method Based on Thom's Catastrophe Theory.
The goal of this work is to develop a new method to achieve higher efficiency and safety in controlling of large-scale systems by Thom' s catastrophe theory. The new method will be introduced by a large-scale system, the steam production technology which includes extremely fast and extremely slow processes. This requirement needs to use safety and fast bi-directional communication. Extremely slow processes require continuous communication with the process to perceive slow and fine changes, ability to distinguish a finite state of process from any temporary state of process, and capability to recognize and evaluate the relatively faster short- time events. Extremely fast processes require high-powered data collection and data conversion, high-speed process control system with extremely short real-time cycle, high computational capability, and high memory capacitance. The tool for this goal is the efficient and accurate real-time control. Technical development in industry requires a harmony between the controlled process, the control system and the human. Some technologies consist of extremely fast and extremely slow processes.
