Book Description
The object of the work performed was to develop a computer controlled data acquisition and data analysis capability for an uninterupted 6,000 hour test to monitor the degradation of approximately 250 infrared light emitting diodes (LED's). The test program comprised subjecting a sampling of 254 diodes to preselected constant currents and temperatures while periodically measuring the voltage drop and the light output of each of the diodes. To perform the data acquisition portion of this effort, an automated data acquisition system was designed around a Hewlett-Packard 2100A computer. This system utilized a 1,000 point random access multiplever, a 16-bit Relay Output Register and a digital voltmeter for data acquisition and transmission. Special purpose assembly language input/output routines were written for the computer's BASIC Interpreter to make this special equipment accessible to the computer. The Control program handled data storage to meet the requirements specified for the project. (Author).

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 23 (thesis year 1978) a total of 10,148 theses titles from 27 Canadian and 220 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 23 reports these submitted in 1978, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

Book Description
Real Time Digital Control Applications is a compilation of papers presented at the Symposium on Real-Time Digital Control Applications, sponsored by the International Federation of Automatic Control (IFAC) and the International Federation for Information Processing (IFIP), held in Guadalajara, Mexico. The event is organized to provide developing countries with the opportunity to gain insights -- from the sharing of ideas and experiences of experts from around the world to the rapid growth and development of applications of real-time digital control systems, which is considered as the basis of industrial revolution. The book presents and discusses the various scientific, industrial, and technical applications of real-time digital control systems. Applications in power generation, water, metal processing, cement, food, and manufacturing industries are shown. The text also covers applications in robotics, biomedicine, monitoring and failure detection, fuel optimization and heat control, adaptive process control, modeling, and computer software. Industrial engineers, scientists, economists, computer scientists, robotics experts, planners, and technicians will find this book invaluable.
