		<description>Covers the full spectrum of component-based software engineering, from the basics to legal aspects.  Contains one of the most authoritative collections of essays and whitepapers on the subject between two covers.  I have used this book as a basis for component-based development, and have also used it as the foundation for a SQA initiative because the material also addresses quality. Many of the essays support a software reuse strategy, which is an added bonus.  Another use of this outstanding book is as a resource for in-house training in many aspects of software engineering outside of the component-based domain. It&#039;s that comprehensive and complete.  I recommend using this book with Successful Software Development as the two primary references in mature development organizations.

		<description>I used this for a design in nature course, yet we ended up spending more time reading journals than really covering any material in the book.  Why?  Because this book is only useful as a primer for the thought of doing a design by looking at nature.  I didn&#039;t really learn or gain any real information by reading this book except for the concept that you can make a very highly simplified assumption of a design created by nature to solve a problem.  For instance, there is nothing more complicated than saying that you can approximate the jump of a grasshopper by a single linear spring or understand that if you look at a wing of a bird you find a similar shape as what you could use on an airplane. This isn&#039;t for &quot;the smart crowd&quot; as stated by the previous reviewer.  Anybody with a high school physics education could easily understand it but in my personal opinion you&#039;re better off finding more inspiration from a popular mechanics magazine.

		<description>This 818 page collection of 42 papers and articles is a definitive work on component-based software engineering.  Regardless of your area(s) of interest, there is probably a chapter that addresses it.  More importantly, each chapter is written by a top expert in their subspecialty.&lt;p&gt;Instead of giving a chapter-by-chapter description, I am going to cover the chapters that I found useful.  To begin, Part II, chapters 1 through 3 gave me a quick primer in software components and highlighted the need to think in a different frame when dealing with component-based development.  If you are new to CBSW then the 48 pages devoted to the basics are worthwhile reading.&lt;p&gt;Part II&#039;s five chapters on making a business and technical case for components is outstanding and the authors cover every facet.  I found Part III, which covers software engineering practices, particularly useful.  The value to me was the status of CBSW engineering on a global scale because I am currently providing consulting services to an India-based company that specializes in components.  For this reason I also found Part IV&#039;s eight chapters on managing component-based software systems especially valuable.&lt;p&gt;The real eye-opener [for me], however, was in Part VIII, which devotes four interesting chapters on aspects of legal and regulatory issues as they related to software development as a discipline, and component-based software engineering specifically.  In particular, chapter 38 on software component standards and certification was enlightening. I was also enlightened by chapter 39&#039;s fascinating discussion on commercial law applicable to component-based software, and the effects of the Uniform Computer Information Transactions Act (UCITA) on component-based software development and marketing.  &lt;p&gt;This is an excellent book that covers the entire landscape of component-based software engineering and, although is a weighty 818 pages, is not difficult to read through.  Each chapter is really a paper or article, so each is standalone.  If you are dealing with off-shore development in any way, the book is especially valuable, and if you are doing CBSW in-house, the key differences between this approach and other development approaches are highlighted and will give you sufficient information with which to approach CBSW intelligently and effectively.

		<description>This is a beautiful book.  French talks about energy, form,
mechanism, and economy in natural and man-made things.  He
compares birds to planes in terms of fuel-capacity, energy
 conversion efficiency, drag, etc.  He compares suspension 
 bridges and dinosaurs.  He provides examples of neat 
 inventions and the thought that has gone into them (every-
 thing from steam-catapults to toy cars to grommets).  This
 is &quot;How Things Work&quot; for the non-moron crowd.

		<description>This book is an excellent collection of articles describing all of the important issues surrounding the construction of component-based software systems. Each chapter describes a different aspect of the question of how to build a system using reusable components. Although each of these chapters is written by a different author or authors, they have been edited so that they read as a continuous whole. It is interesting that the editors were able to get some of the biggest names in the field to write articles on their specialties. A look at the author biographies show that they include industry practitioners, academics, industrial researchers, and independent consultants. Together they have a very impressive amount of experience and varied expertise. Perhaps my only complaint is that because so many different topics are covered, and each article is rather brief, some of the articles just touch the surface of the issues. But they do provide a balanced picture of these issues which then allow you to go out and do further in-depth reading on salient topics using the included list of references.

		<description>Finally a book on applied performance engineering, not just theory.  I have been looking for a practical approach to frame our capacity planning and performance engineering efforts. The authors do a fantastic job of giving you real world examples that you can apply to your job.

		<description>In my opinion is this the best you can buy for your money. It is not cheap, but worth every cent of it. I call it the antenna bible, use it together with good antenna design software and understand what you design.

		<description>No more Worries!!! All you need to know is right here in this book. From theory to industry applications; the book is today&#039; Antenna Engineers best reference. Each chapter is written by an expert in the field, and when I  say experts I mean REAL Experts!! The book is a collection of chapters  written by the most knowledgeable people in Today&#039;s Antenna world. It is  easy to read, and it includes everything from theory, formulas, design  techniques, to REAL WORLD EXAMPLES.. this is the best book your money can  buy. However you might want to wait for the new edition to come out,  because it is coming out VERY SOON. It will include more topics on Cellular  phone antennas as well as communication antennas for PCS industry.

		<description>This book, a compilation of 33 articles covering many different aspects and applications of Clifford algebras, can be read profitably by anyone desiring an overview of their history, theory, and applications. I did not read every article, and space also prohibits such a comprehensive review, so I will comment only on the ones that I actually studied. &lt;p&gt;Chapter introduces Clifford algebras as an extension of the real numbers to include vectors and vector products. The familiar representation in Euclidean space is outlined, with emphasis on the exterior product of two vectors, which, the author points out, is associative (unlike the ordinary cross product). The connection with rotations, reflections, and volume elements is pointed out, and the complex numbers and the Pauli algebra are shown to be Clifford algebras. &lt;p&gt;A short history of Clifford algebras is given in chapter 2. The reader not familiar with Clifford algebras should have no trouble following the ensuing discussion where some elementary geometric constructions are given of the Clifford algebra on the Euclidean plane. In addition, the operator approach to Weyl, Majorana, and Dirac operators is given, illustrating in detail their connection to physics. Recognizing that the Fierz identities do not by themselves give the Weyl and Majorana spinors, the author introduces what he calls the boomerang method for their construction. The boomerang is essentially a linear combination of bilinear covariants for a spinor, and the author details the conditions under which the spinor can be reconstructed. Interestingly, and unknown to me at the time of reading this chapter, the author constructs a new class of spinors, the &quot;flag-dipole&quot; spinors, that are different from the Weyl, Majorana, and Dirac spinors. &lt;p&gt;The author of chapter 3 considers the construction of Clifford algebras from a more geometric viewpoint, calling them geometric algebras, which he motivates by the consideration of extending the reals by a unipotent ( a number not equal to +1 or -1 but whose square is 1). The resulting unipodal numbers are isomorphic to the diagonal 2 x 2 matrices. The extension of the unipodal numbers so as to make this isomorphism to the full 2 x 2 matrix algebra leads to Clifford algebras. &lt;p&gt;In Chapter 9, the spacetime algebra is brought in to study electron physics. The &quot;space-time algebra&quot; or STA is used to characterize the observables associated with Pauli and Dirac spinors. The material presented is standard in physics, wherein the Green&#039;s function (propagator) for the Dirac equation is given, along with scattering theory. The typical problem of scattering off a potential barrier of finite width is discussed, along with the Klein paradox.  &lt;p&gt;The space-time algebra is also discussed in the context of the interpretation of quantum mechanics in Chapter 11. The authors really do not add anything new here (in  terms of what one might consider &quot;strange&quot; behavior in quantum physics). They interpret Dirac currents as measurable quantities, avoiding seemingly any notion of wave packet collapse and difficulties with defining tunneling time(s), but not answering at all how to measure these currents. In addition, the Pauli principle is interepreted in the context of space-time algebra, without any quantum field theory. Howerver, it is not shown that such an approach satisfies cluster decomposition, casting suspicion on its utility. &lt;p&gt;In Chapters 21, 22, and 23 the author shows how spinors fit into the framework of the Lorentz group, their relationship to the Clifford algebra, and in general relativity. It is shown how the Dirac spinor can be defined in three different ways, namely as an element of the representation space of the Clifford algebra of spacetime, an element of the representation space of the fundamental representation of the Dirac spinor metric-preserving automorphism group of the Clifford algebra, and as an element of the representation space of the fundamental representation of the covering group of the conformal group. &lt;p&gt;The most interesting discussion in the book is chapter 28 on extending the Grassmann algebra. Dispensing with any scalar product on a vector space, the author shows how to obtain the relative magnitude between two vectors and this leads to the notion of a multivector. The duals to these are called outer forms, and are the familiar differential forms when depending on spatial position. Many helpful diagrams are used to illustrate the properties of multivectors and pseudomultivectors, the linear span of which is called the extended Grassmann algebra of multivectors. Adding a scalar product reduces the number of directed quantities to four, and electrodynamics can be formulated in a way that is independent of the scalar product.
