Biological invasions are one of the major threats to our native biodiversity. The magnitude of biodiversity losses, land degradation and productivity losses of managed and natural ecosystems due to invasive species is enormous. The ecological and environmental aspects of non-native invasive plants are of great importance to (i) understand ecological principles involved in the management of invasives, (ii) design management strategies, (iii) find effective management solutions for some of the worst invaders, and (iv) frame policies and regulations. The objectives of this book are to discuss (i) ecological approaches needed to design effective management strategies, (ii) recent progress in management methods and tools, (iii) success and failure of management efforts for some of the worst invaders, and (iv) restoration and conservation of invaded land. In an effort to achieve these objectives, contributing authors have strived to provide up-to-date information on the management of non-native invasives. Chapters included in the book are peer-reviewed by international experts working in the area. Readers will get a unique perspective on ecological aspects of the management of invasives. The book will be useful to graduate students, researchers, managers and policy makers involved in the management of exotic invasives.

Frequency synthesizers are an essential building block of RF communication products. They can be found in traditional consumer products, in personal communication systems, and in optical communication equipment. Since frequency synthesizers are used in many different applications, different performance aspects may need to be considered in each case. The main body of the text describes a conceptual framework for analyzing the performance of PLL frequency synthesizers, and presents optimization procedures for the different performance aspects. The analysis of the PLL properties is performed with the use of the open-loop bandwidth and phase margin concepts, to enable the influence of higher-order poles to be taken into account from the beginning of the design process. The theoretical system analysis is complemented by descriptions of innovative system and building block architectures, by circuit implementations in bipolar and CMOS technologies, and by measurement results. Architectures for RF Frequency Synthesizers contains basic information for the beginner as well as in-depth knowledge for the experienced designer. It is widely illustrated with practical design examples used in industrial products.

Many cooling systems use water as cooling medium. They are found in public buildings, industrial production systems or power plants. Almost every cooling system using water is degraded by deposition, corrosion and microbiological fouling. This book identifies the whole bunch of problems due to water cooling systems and proposes specific solutions to all of them. The authors have an expertise of over 20 years solving cooling water problems. In this book, they advise all practitioners which need to plan, buy or operate cooling systems.

The study of plant invasions is the science that attempts to understand causes and consequences of plant introductions outside of their native areas. Invasive plants have an impact on global biodiversity and ecosystem function, and their management is a complex and formidable task. The applied aspects of this study include the health and economic impacts of invasions. Although research on plant invasions has progressed remarkably during the past several decades, scientists are still looking for answers to basic questions. Such questions are: (1) What are invaders? (2) Can we predict invaders? (3) What are mechanisms of exclusion of native species by invaders? (4) How general principles in ecology can be used to predict and understand plant invasions? (5) What makes a habitat susceptible to invasion? (6) What agricultural practices influence invasion? (7) What impact invaders may have on ecosystem processes and community structure? (8) What are causes, mechanisms and consequences of plant invasions (9) What are the environmental and economic costs of invasion? (10) What management strategies are needed to check invasion? In an effort to answer these questions, contributing authors have strived to provide up-to-date reviews and discussions of invasion-related research involving natural and agroecosystems. Readers will get a unique perspective on ecological and agricultural aspects of plant invasions through employing general principles of ecology to plant invasions.

Low-Power High-Level Synthesis for Nanoscale CMOS Circuits addresses the need for analysis, characterization, estimation, and optimization of the various forms of power dissipation in the presence of process variations of nano-CMOS technologies. The authors show very large-scale integration (VLSI) researchers and engineers how to minimize the different types of power consumption of digital circuits. The material deals primarily with high-level (architectural or behavioral) energy dissipation because the behavioral level is not as highly abstracted as the system level nor is it as complex as the gate/transistor level. At the behavioral level there is a balanced degree of freedom to explore power reduction mechanisms, the power reduction opportunities are greater, and it can cost-effectively help in investigating lower power design alternatives prior to actual circuit layout or silicon implementation. The book is a self-contained low-power, high-level synthesis text for Nanoscale VLSI design engineers and researchers. Each chapter has simple relevant examples for a better grasp of the principles presented. Several algorithms are given to provide a better understanding of the underlying concepts. The initial chapters deal with the basics of high-level synthesis, power dissipation mechanisms, and power estimation. In subsequent parts of the text, a detailed discussion of methodologies for the reduction of different types of power is presented including: ¢ Power Reduction Fundamentals ¢ Energy or Average Power Reduction ¢ Peak Power Reduction ¢ Transient Power Reduction ¢ Leakage Power Reduction Low-Power High-Level Synthesis for Nanoscale CMOS Circuits provides a valuable resource for the design of low-power CMOS circuits.
