A new class of methods, termed "group explicit methods," is introduced in this text. Their applications to solve parabolic, hyperbolic and elliptic equations are outlined, and the advantages for their implementation on parallel computers clearly portrayed. Also included are the introductory and fundamental concepts from which the new methods are derived, and on which they are dependent. With the increasing advent of parallel computing into all aspects of computational mathematics, there is no doubt that the new methods will be widely used.

Scattered among beautiful rural landscapes around England are ancient standing stones and the remains of many different kinds of megalithic and neolithic monuments. In this book David J. Evans follows on from his previous publication Stone Circles in Britain to explore the sites of the standing stones and other similar megalithic and neolithic structures around England. The meaning and purpose of some of these stones and structures is often unclear today, but many are believed to have a ritual significance or to be aligned astronomically. Not only single or double-standing stones, stone rows and settlements are investigated, but also the wealth of various burial chambers such as mounds, cairns, cists, dolmens, long barrows, tumps and quoits.This fascinating picture of this important legacy from the prehistory of Britain will be of interest to all those who have seen and visited these mysterious stones and structures around England.

Because the World Matters.New generations are championing responsibility for both the environment and those peoples who depend upon it in all new ways. Biblical Holism and Agriculture addresses the urgent need for constructing a holistic perspective, grounded in the Bible, to appraise the economic, social, ecological, environmental, and spiritual impact of globalization and the unprecedented impact of powerful agricultural technologies, and marketing systems. The holistic biblical perspectives within reference ancient Hebrew insights about responsible freedom for “keeping” the land by people created in the image of God as representatives commissioned to stewardship and justice.

While the architecture of present-day parallel supercomputers is largely based on the concept of a shared memory, with its attendant limitations of common access, advances in semicoductor technology have led to the development of highly parellel computer architectures with decentralized storage and limited connections in which each processor possesses high bandwidth local memory connected to a small number of such architectures, enabling cost-effective high-speed parallel processing for large volumes of data, with ultra-high throughput rates. Algorithms suitable for implementation on systolic arrays find applications in areas such as signal and image processing, pattern matching, linear algebra, recurrence algorithms and graph problems. This book provides an insight into the implementation of systolic arrays and gives a comprehensive overview of the techniques and theories contributing to the design of systolic algorithms.
