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.
There are many hundreds of stone circles around Britain. Most were
built in the Late Neolithic or early Bronze Age eras and can be
found throughout England, Wales and Scotland, although there are
concentrations in the more remote and upland areas. It is not known
for certain why they were built but they are believed to have a
ritual or ceremonial purpose and are often aligned to the sun or
moon and many were also burial sites. In this book author Cozmic
Dave surveys the stone circles of Britain. He travels from
Scotland, to Wales and England, and surveys not only the famous
sites of Stonehenge and Avebury but many other stone circles
throughout Britain. From Orkney and the Hebrides and the Scottish
mainland, to Northern England including the Lake District, Wales,
the heart of England and the South Western counties of England, the
huge variety of stone circles around Britain are revealed. 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 structures around England, Scotland and Wales.
Central to the future direction of mankind on planet Earth is the
belief that the origination and design of the Universe and the plan
by which it operates are the work of one almighty creator. If one
follows the view that a motor car comes into existence by way of
the design and manufacture process or that a building is the end
result of the design and construct process, then it is a simple
progression to believe that the Universe and its modus operandi
were designed and brought into existence by one superior being.
Peter Vanser, an avid star gazer and amateur astronomer, has for
several months been watching rapidly moving lights over the Pacific
Ocean off the Gold Coast in Australia. The Commanding Officer of a
mission from the Planet Gronorg, in the Orion Constellation, has
been attempting to communicate with Earthian leaders via coded
transmissions, all to no avail.The mission commander, Mar Zedok,
wants to land on Earth to convey important information on an
impending attack by an aggressive alien civilization. Vanser is
approached personally by a Gronorgan operative and is invited to
visit Gronorg to experience their social fabric and intelligence.

Presenting the main recent advances made in parallel processing, this volume focuses on the design and implementation of systolic algorithms as efficient computational structures that encompass both multiprocessing and pipelining concepts.;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 semiconductor technology have led to the development of highly parallel computer architectures with decentralized storage and limited connections in which each processor possesses high bandwidth local memory connected to a small number of neighbours. Systolic arrays are a typical and highly efficient example 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.
