This book contains the historical development of the seminal paper of Adolf Hurwitz, professor in mathematics at ETH (1892 1919), and its impact on other fields. The major emphasis, however, is on modern results in stability theory and its application in the theory of control and numerics. In particular, stability of the following problems is treated: linear, nonlinear and time-dependent systems, discretizations of ordinary and partial differential equations, systems with time delay on multidimensional systems. In addition robust stability, pole placement and problems related to the stability radius are treated. The book is an outgrowth of the international conference "Centennial Hurwitz on Stability Theory" which was held to honor Adolf Hurwitz, whose arti cle on the location of roots of a polynomial was published one hundred years ago. The conference took place at the Centro Stefano Franscini, Monte Verita, Ascona, Switzerland, on May 21 26, 1995. This book contains a collection of the papers and open problem: discussed all that occasion. Leading researchers from allover the world working on stability theory and its application were invited to present their recent results. In one paper the historic development initiated by Hurwitz's article was discussed."

Fate and Prediction of Environmental Chemicals in Soils, Plants, and Aquatic Systems focuses on the chemical persistence and ecotoxicological behavior of pesticides in soil, water, and plants. The book examines recent developments in research on various substances and relays information regarding transport, adsorption, absorption, accumulation, degradation, biological effects, toxicity to aquatic organisms, air pollution, exposure, and risk estimation. Leading international scientists present their advances in analytical methodology and instrumentation in the fields of agrochemicals and environmental chemistry. This useful review of data, methods, and principles will benefit environmental researchers, managers, biologists, chemists, pharmacologists, and others interested in assessing the potential for contamination of soil, air, water, and plants.

Robust Control is one of the fastest growing and promising areas of research today. In many practical systems there exist uncertainties which have to be considered in the analysis and design of control systems. In the last decade methods were developed for dealing with dynamic systems with unstructured uncertainties such as HOO_ and GBPI-optimal control. For systems with parameter uncertainties, the seminal paper of V. L. Kharitonov has triggered a large amount of very promising research. An international workshop dealing with all aspects of robust control was successfully organized by S. P. Bhattacharyya and L. H. Keel in San Antonio, Texas, USA in March 1991. We organized the second international workshop in this area in Ascona, Switzer land in April 1992. However, this second workshop was restricted to robust control of dynamic systems with parameter uncertainties with the objective to concentrate on some aspects of robust control. This book contains a collection of papers presented at the International Workshop on Robust Control held at the Centro Stefano Franscini, Monte Verita, Ascona, Switzer land on April 12-17, 1992 as well as a list of open problems presented during a dis cussion session at the workshop. Thirtyfive leading researchers from all over the world working in the area of robust control of dynamic systems with parameter uncertainties were invited to present their recent results and to discuss with their colleagues the recent advances in this field.

Mohamed Mansour has spent his life fighting adversity. Born in Egypt in the post-war period, his childhood was halted abruptly when, aged ten, he almost lost a leg in a devastating car accident. At 18, he had to support himself through college in the US when his family's assets were seized by the Egyptian government. Aged 20, he fought cancer. Then, at 25, he returned to Egypt to help revive the fortunes of his family's once thriving business group as it steadily diversified into sectors from automobiles to construction equipment, fast food to venture capital. Almost five decades on, he and his family stand at the helm of some of the largest companies in North Africa and the Middle East. They have partnered with global brands from General Motors and Caterpillar to McDonald's and invested early in Silicon Valley successes such as Facebook, Uber and Airbnb. He also served as Egypt's Transport Minister from 2005 to 2009. Filled with hard-won wisdoms, Mohamed Mansour's inspirational story demonstrates the importance of learning from experience and never giving up in the drive to succeed.

This book looks at the modern electrical energy meter reading. It investigates the application for power line carrier as the communication medium between the meters and the power system. Electric meters are the building blocks of the future smart network applications. Moreover, it illustrates the use of meters as a means for load control which is a necessary aspect for modern Demand Side management. The proposed concepts have been experimentally verified over a sample low voltage distribution network.
