CONTINUOUS AND DISCRETE SIGNALS AND SYSTEMS

This book provides an introductory but comprehensive treatment of the subject of continuous- and discrete-time signals and systems. The aim of building complex systems that perform sophisticated tasks imposes on engineering students a need to enhance their knowledge of signals and systems so that they are able to use effectively the rich variety of analysis and synthesis techniques that are available. This may explain why the subject of signals and systems is a core course in the electrical engineering curriculum in most schools. In writing this book, we have tried to present the most widely used techniques of signal and system analysis in an appropriate fashion for instruction at the junior or senior level in electrical engineering. The concepts and techniques that form the core of the book are of fundamental importance and should prove useful also to engineers wishing to update or extend their understanding of signals and systems through self-study.

An Introduction to Complex Analysis for Engineers

These notes are intended to be of use to Third year Electrical and Elec- tronic Engineers at the University of Western Australia coming to grips with Complex Function Theory.. There are many text books for just this purpose, and I have insufficient time to write a text book, so this is not a substitute for, say, Matthews and Howell's Compler Analysis for Mathematics and Engineering, 1, but perhaps a complement to it. At the same time, knowing how reluctant students are to use a textbook (except as a talisman to ward off evil) I have tried to make these notes sufficient, in that a student who reads them, understands them, and does the exercises in them, will be able to use the concepts and techniques in later years. It will also get the student comfortably through the examination. The shortness of the course, 20 lectures, for covering Complex Analysis, either presupposes genius (90% perspiration) on the part of the students or material skipped. These notes are intended to fill in some of the gaps that will inevitably occur in lectures. It is a source of some disappointment to me that I can cover so little of what is a beautiful subject, rich in applications and connections with other areas of mathematics. This is, then, a sort of sampler, and only touches the elements.

CODING INFORMATION IN NATURAL LANGUAGES

The debate concerning the Chomskyan variety of transformational theory has centered around the dual question of whether or not language is intrinsically structured for communication, and whether or not it can be effectively analyzed apart from its communicative function. This monograph argues that language must be dealt with in its communicative function in order to account for its structure and its use. This view amounts to a basic departure from the thinking of American structural linguistics since the time of Bloomfield. It suggests an approach to linguistic analysis which is essentially different from the currently dominant variety of transformational generative theory. The present work constitutes an attempt to justify and outline an approach to the study of language as an instrument for coding cognitive information. An attempt is made to clarify certain confusions about the notions ‘competence’ and ‘performance’, and the theory of ‘innate ideas’ is challenged as naively motivated as a result of the failure of transformationalists to treat language as a medium of communication.

CLASSICAL MECHANICS

More than a generation of German-speaking students around the world have worked their way to an understanding and appreciation of the power and beauty of modern theoretical physics with mathematics, the most fundamental of sciences-using Walter Greiner's textbooks as their guide. The idea of developing a coherent, complete presentation of an entire field of science in a series of closely related textbooks is not a new one. Many older physicians remember with real pleasure their sense of adventure and discovery as they worked their ways through the classic series by Sommerfeld, by Planck, and by Landau and Lifshitz. From the students' viewpoint, there are a great many obvious advantages to be gained through the use of consistent notation, logical ordering of topics, and coherence of presentation; beyond this, the complete coverage of the science provides a unique opportunity for the author to convey his personal enthusiasm and love for his subject.

CLASSICAL MECHANICS: A Modern Perspective

In the twenty-one years that have elapsed since the original edition was published, we have collected many ideas for improvements. In deciding which changes to make, we have continued with our original philosophy of a reasonably concise presentation that includes numerous applications of interest in t he real world. By incorporating feedback from students in our classes, we have t ried to make the textbook even more student friend ly. One of the salient features of the first edition was the introduction of Lagrangian meth.ods at an early stage. In t he new edition more Lagrangian material and examples are included which made it natural to devote a single chapter to an introduction to the Lagrangian approach. We have integrated a parallel track development of Lagrangian and Newtonian methods t hroughout the text.

Explaining and Exploring Mathematics

Explaining and Exploring Mathematics is designed to help you teach key mathematical concepts in a fun and engaging way by developing the confidence that is vital for teachers. This practical guide focuses on improving students’ mathematical understanding, rather than just training them for exams. Covering many aspects of the secondary mathematics curriculum for ages 11–18, it explains how to build on students’ current knowledge to help them make sense of new concepts and avoid common misconceptions. Focusing on two main principles to improve students’ understanding: spotting patterns and extending them to something new, and relating the topic being taught to something that the pupils already understand, this book helps you to explore mathematics with your class and establish a successful teacher-student relationship.

Bulgarian Mathematical Olympiad 1960 - 2008

In a cone is inscribed a sphere. Then it is inscribed another sphere tangent to the first sphere and tangent to the cone (not tangent to the base). Then it is inscribed third sphere tangent to the second sphere and tangent to the cone (not tangent to the base). Find the sum of the surfaces of all inscribed spheres if the cone’s height is equal to h and the angle throught a vertex of the cone formed by a intersection passing from the height is equal.
