"Simple text and full-color photography introduce beginning readers to adders. Developed by literacy experts for students in kindergarten through third grade"--
In 2019 the most comprehensive survey ever of adders was published. According to ‘Make the Adder Count’ the species will disappear from most of Britain in the next 15-20 years unless we take action now to save it. But despite being a priority conservation species under the Biodiversity Action Plan, not a single nature reserve in Britain has been specifically designated to protect it. Throughout our history we have systematically persecuted the adder over generations because it is Britain’s only venomous snake. Now the adder population is in dire straits, its rapidly declining numbers occurring on increasingly small, isolated and fragmented sites. According to Make the Adder Count 90% of the sites where it still occurs have 10 or less adult snakes and are now considered to be very vulnerable to local extinction. Despite the adder population being in dire straits, it is still not too late to save it if we act now. This book contains a 10 point adder action plan which if implemented could help to restore the adder to its former range across Britain. Using many unique photographs of the species published for the first time, it also contains a history of the adder and reveals its secret life which has made it the most successful snake in the world. With a foreword by Iolo Williams, the BBC Springwatch presenter, this book is a story of our times, one which typifies the age of extinction through which we are all living and are all responsible.
Introduces characteristics, habitat, and behaviors of the Common adder snake.
This book serves as a single-source reference to the latest advances in Approximate Computing (AxC), a promising technique for increasing performance or reducing the cost and power consumption of a computing system. The authors discuss the different AxC design and validation techniques, and their integration. They also describe real AxC applications, spanning from mobile to high performance computing and also safety-critical applications.
The book provides many of the basic papers in computer arithmetic. These papers describe the concepts and basic operations (in the words of the original developers) that would be useful to the designers of computers and embedded systems. Although the main focus is on the basic operations of addition, multiplication and division, advanced concepts such as logarithmic arithmetic and the calculations of elementary functions are also covered. This volume is part of a 3 volume set: Computer Arithmetic Volume I Computer Arithmetic Volume II Computer Arithmetic Volume III The full set is available for sale in a print-only version.

This text is designed to document and unify much of the theory, techniques, and understanding about pipelining, presenting the material so that the reader can recognize and use the techniques in future design. It is more of an engineering than a theoretical text; discussions range from logic design considerations, through the construction, cascading, and control of pipelined structures, to the architecture of complete systems and the development of programming techniques to efficiently use such machines. Examples from real are used whenever possible to amplify the development and presentation of concepts.
In response to tremendous growth and new technologies in the semiconductor industry, this volume is organized into five, information-rich sections. Digital Design and Fabrication surveys the latest advances in computer architecture and design as well as the technologies used to manufacture and test them. Featuring contributions from leading experts, the book also includes a new section on memory and storage in addition to a new chapter on nonvolatile memory technologies. Developing advanced concepts, this sharply focused book— Describes new technologies that have become driving factors for the electronic industry Includes new information on semiconductor memory circuits, whose development best illustrates the phenomenal progress encountered by the fabrication and technology sector Contains a section dedicated to issues related to system power consumption Describes reliability and testability of computer systems Pinpoints trends and state-of-the-art advances in fabrication and CMOS technologies Describes performance evaluation measures, which are the bottom line from the user’s point of view Discusses design techniques used to create modern computer systems, including high-speed computer arithmetic and high-frequency design, timing and clocking, and PLL and DLL design
This book constitutes the refereed proceedings of the Third International Conference on Embedded Software and Systems, ICESS 2007, held in Daegu, Korea, May 2007. The 75 revised full papers cover embedded architecture, embedded hardware, embedded software, HW-SW co-design and SoC, multimedia and HCI, pervasive/ubiquitous computing and sensor network, power-aware computing, real-time systems, security and dependability, and wireless communication.

Computers are everywhere around us. We, for example, as air passengers, car drivers, laptop users with Internet connection, cell phone owners, hospital patients, inhabitants in the vicinity of a nuclear power station, students in a digital library or customers in a supermarket are dependent on their correct operation. Computers are incredibly fast, inexpensive and equipped with almost unimag- able large storage capacity. Up to 100 million transistors per chip are quite common today - a single transistor for each citizen of a large capital city in the world can be 2 easily accommodated on an ordinary chip. The size of such a chip is less than 1 cm . This is a fantastic achievement for an unbelievably low price. However, the very small and rapidly decreasing dimensions of the transistors and their connections over the years are also the reason for growing problems with reliability that will dramatically increase for the nano-technologies in the near future. Can we always trust computers? Are computers always reliable? Are chips suf- ciently tested with respect to all possible permanent faults if we buy them at a low price or have errors due to undetected permanent faults to be discovered by c- current checking? Besides permanent faults, many temporary or transient faults are also to be expected.
