Portable Design

All the design and development inspiration and direction an electronics engineer needs in one blockbuster book! John Donovan, Editor-in Chief, Portable Design has selected the very best electronic design material from the Newnes portfolio and has compiled it into this volume. The result is a book covering the gamut of electronic design from design fundamentals to low-power approaches with a strong pragmatic emphasis. In addition to specific design techniques and practices, this book also discusses various approaches to solving electronic design problems and how to successfully apply theory to actual design tasks. The material has been selected for its timelessness as well as for its relevance to contemporary electronic design issues.

The increasing interest in the bio-impedance analysis in various fields has increased the demand for portable and low-cost impedance analyzers that can be used in the field. Simplifying the hardware is crucial to maintaining low-cost and portability, but this is not an easy task due to the need for accurate phase and magnitude measurements. This book discusses different portable impedance analyzers design techniques. Additionally, complete designs using two different approaches are reported. The first approach utilizes a commercially available single chip solution while the second one is based on a new measurement technique that eliminates the need to measure the phase by using a software algorithm to extract it from the magnitude information. Applications to the measurement of fruit bio-impedance are emphasized and compared with measurements from professional stand-alone impedance analyzers.

Infuse your quilts with love--how to add your personal story and more meaning to your handmade quilts. In Wise Craft Quilts, celebrated quilt designer and crafter Blair Stocker shares ways to use cherished fabrics to make quilts with more meaning. Each of the twenty-one quilts featured here gathers a special collection of fabric, outlines a new technique, and spins a story. By using special fabrics as the starting point for each project—from a wedding dress to baby’s first clothes, worn denim, Tyvek race numbers, and more—the finished quilt is made even more special. Create quilts that have a story to tell and you’ll find a whole new level of appreciation for what they represent in your life and the lives of the ones you love.

Ideal for those who have been commissioned, or are in competition, who want to learn about the very latest developments and trends in the area. New introductions to each section focus the remit of the book and make it a complete and comprehensive guide to the topic.

This book discusses the forerunners, present context, and technology of portable architecture. It documents numerous international examples, organized by areas of application, and offers a broad array of suggestions for practical design.

With the availability of advanced technologies, digital systems, and communications, portable instruments are rapidly evolving from simple, stand alone, low-accuracy measuring instruments to complex multifunctional, network integrated, high-performance digital devices with advanced interface capabilities. The relatively brief treatments these instr

Inhaltsangabe:Abstract: Even though the benefits of mobile agents have been highlighted in numerous research works, mobile agent applications are not in widespread use today. For the success of mobile agent applications, secure, portable, and efficient execution platforms for mobile agents are crucial. However, available mobile agent systems do not meet the high security requirements of commercial applications, are not portable, or cause high overhead. Currently, the majority of mobile agent platforms is based on Java. These systems simply rely on the security facilities of Java, although the Java security model is not suited to protect agents and service components from each other. Above all, Java is lacking a concept of strong protection domains that could be used to isolate agents. The J-SEAL2 mobile agent system extends the Java environment with a model of strong protection domains. The core of the system is a micro-kernel fulfilling the same functions as a traditional operating system kernel: Protection, communication, domain termination, and resource control. For portability reasons, J-SEAL2 is implemented in pure Java. J-SEAL2 provides an efficient communication model and offers good scalability and performance for large-scale applications. This thesis explains the key concepts of the J-SEAL2 micro-kernel and how they are implemented in Java.
