  • There are notes of course of lectures on Field theory aimed at providing the beginner with an introduction to algebraic extensions, algebraic function fields, formally real fields and valuated fields. These lectures were preceded by an elementary course on group theory, vector spaces and ideal theory of rings—especially of Noetherian rings. A knowledge of these is presupposed in these notes.

  • In this paper, we present two vector-level software algorithms which essentially eliminate such bit-wise operations for Gaussian normal bases. Our analysis and timing results show that the software implementation of the proposed algorithm is faster than previously reported normal basis multiplication algorithms.

  • A vector is a quantity that possesses both magnitude and direction. Examples of vector quantities are displacement, velocity, acceleration, and force. A vector quantity can be represented by an arrow drawn to scale. The length of the arrow is proportional to the magnitude of the vector quantity. The direction of the arrow represents the direction of the vector quantity.physics in general is the most scientific study of "physical" and "interaction".

  • The main reason for a fourth edition of Essential MATLAB for Engineers and Scientists is to keep up with MATLAB, now in its latest version (7.7 Version 2008B). Like the previous editions, this one presents MATLAB as a problemsolving tool for professionals in science and engineering, as well as students in those fields, who have no prior knowledge of computer programming.

  • From the principles of electrical engineering it is known that the 3-phase quantities of the 3-phase AC machines can be summarized to complex vectors. These vectors can be represented in Cartesian coordinate systems, which are particularly chosen to suitable render the physical relations of the machines. These are the field-orientated coordinate system for the 3- phase AC drive technology or the grid voltage orientated coordinate system for generator systems.

  • Security has become a major concern for every network administrator. Nearly every day we are bombarded with news articles describing yet another high-profile company that has fallen prey to a network-based attack. To fill in the occasional gap, we hear about new viruses that have been found “in the wild” or about additional software vulnerabilities that someone has figured out how to exploit for personal gain. The network security field has not always been this crazy. Most of us can remember a time when securing a network environment was a far easier task.

  • Electromagnetic Field Theory: A Problem Solving Approach Part 1. Electromagnetic field theory is often the least popular course in the electrical engineering curriculum. Heavy reliance on vector and integral calculus can obscure physical phenomena so that the student becomes bogged down in the mathematics and loses sight of the applications. This book instills problem solving confidence by teaching through the use of a large number of worked problems. To keep the subject exciting, many of these problems are based on physical processes, devices, and models.

  • an one learn linear algebra solely by solving problems? Paul Halmos thinks so, and you will too once you read this book. The Linear Algebra Problem Book is an ideal text for a course in linear algebra. It takes the student step by step from the basic axioms of a field through the notion of vector spaces, on to advanced concepts such as inner product spaces and normality. All of this occurs by way of a series of 164 problems, each with hints and, at the back of the book, full solutions. This book is a marvelous example of how...

  • The fields of cosmology and particle astrophysics (sometimes collectively named astroparticle physics) are currently experiencing an era which will most probably be remembered as ‘the golden age’. The developments during the last few years have been truly astonishing, and the planning and building of new detectors, telescopes and other experimental facilities will guarantee an interesting decade to follow.
