The Practical Performance Analyst Review

Average Reviews:

(More customer reviews)If understanding and managing computer systems performance is in your job description and you can only buy two books, this is one of the two (the other is Raj Jain's, "The Art of Computer Systems Performance..."). Neil Gunther's book is not just another tome on queueing theory. Immediately useful methods and formulas are presented in the context of real problems. The two chapters on instability in systems and scaling of multiprocessor systems alone make the book worth its price. Readers need to know that there is some math in the book (there is just no escaping it) and that some of the cited vendor products are becoming dated. The Web site associated with the book contains many items of current interest, an errata sheet correcting minor errors in the book, and downloadable programs related to performance evaluation.

Database Design and Programming for DB2/400 Review

Average Reviews:

(More customer reviews)I wish I had this book as soon as it was published. After programming on the S/38 and the AS/400 (in RPG) for over 14 years now (with some interruptions), I consider this one the best AS/400-related computing book I have purchased - ever! And compared to other computer books, well, if only that kind of quality would be available on other topics as well more frequently, either DBMS's or programming languages. The book saved one of my clients hours of work: with no previous SQL knowledge but having this book they were able to do some work with SQL that otherwise would have required them to write a program. Another client (and myself for my own system) took advantage of the chapters on Referential Integrity. If you're serious about accessing your data on your DB2/400 database, you owe it to yourself to buy this book !

Data Structures in Java Review

Average Reviews:

(More customer reviews)As a student who completed a data structures course using this book, I believe that I can offer a review that has special insight that might be lacking in a typical review.
Overall, the book is very solid, and it accomplishes its purpose. Standish takes a naturally abstract topic and provides numerous visuals and models to help the student visualize ADT's. Without these models, a data structures book would not only be extremely dry, but also difficult to follow. This is certainly the book's strong point. There is no doubt in my mind that Standish is a great teacher of data structures because of this. Also noteworthy is the setup of the book. Recursion, a difficult but essential topic in computer science, is covered early on. For the CS2 programmer, recursion can be very difficult at times, and it is critical that the reader understands the value of incorporating this technique into ADT programs. In addition, chapter 5 covers modularity and information hiding, which partially introduces the essence behind ADT's. I think this is a great placement of this chapter, because when we get into real ADT's, like Stacks and Queues, we understand the purpose of ADT's: all we need to know now is the operations that Stacks and Queues have to offer. In short, this placement of the chapters allows for quick and easy understanding of a subject that is not concrete by definition. Another good point is its sorting chapter, which covers almost any sorting and searching algorithm you could think of, including Radix Sort and ProxMap sort, which are difficult, if not impossible, to find in other data structures books.
The only negative point about the book is the price. For its price, the books should be 50-100 pages longer. And by that, I don't mean extending long appendices, which contribute to the mediocre thickness of the book already. When I finished the book, I thought I got most of what data structures in computer science had to offer. But I was dead wrong. I found another book (I don't recall the author) that covered trees which I never heard of, and other advanced ADT's like binomial queues. Sorry, you won't find anything like this in this book. In addition, there just aren't enough exercises offered in this book that present any real challenge. That may be up to the ability level of the programmer, but in most exercises, all that is required to complete them is just a simple modification of a source code example. That, in my judgment, is not enough if one wants to build up any skills in programming.
In conclusion, the book may have its shortcomings, particularly in its length, but overall, its fabulous explanations of an obscure topic more than make up for any faults. This book is excellent for an intro to data structures ONLY!

Using Java 1.1, this book teaches the fundamentals of data structures and algorithms. With this exciting new language, Tim Standish takes a fresh look at the subject matter. New challenges arise any time a new language is used, and the author meets these challenges. For example, although Java is a language without explicit pointers, this book offers pointer diagrams to help students visualize, reason about, and understand this major Data Structures topic. Standish's clear presentation helps readers tie the many concepts of data structures together with recurring themes. Central ideas-such as modularity, levels of abstraction, efficiency, and tradeoffs-serve as integrators in the book in order to tie the material together conceptually and to reveal its underlying unity and interrelationships.

Calibration and Orientation of Cameras in Computer Vision (Springer Series in Information Sciences) Review

Average Reviews:

(More customer reviews)This book presents two approaches for camera calibration. The first approach explains the photogrammetric principles of camera calibration. The second one explains the computer vision point of view. Photogrammetry by its very nature aims at rigorous modeling from images. Therefore, the physical and the geometric aspects of camera calibration are treated in great depth. In addition, the random component associated with the observed information is treated in a correct statistical sense. The collinearity model is central to most of the photogrammetric calibration algorithms. On the other hand, computer vision algorithms, in general, mainly concentrate on producing quick and fast algorithms to comply with the nature of their applications. Linear models are the driving force behind most of these algorithms. There is a great synergy between the two approaches if it exploited with a deep understanding. Well-known researchers in photogrammetry and computer vision author this book. I recommend this book.

Object-Process Methodology Review

Average Reviews:

(More customer reviews)I have used many methodologies over my career. Most of them are based around the object-oriented and structured design paradigms. I found out about OPM quite by accident about a year ago. I've been using it ever since. I have used it to model both hardware and software systems, as well as for business process modeling. It is an excellent methodology and I recommend it for anyone developing any kind of system.
One of the nice things about OPM is that it is easy: I was able to get a team "up-and-running" with the methodology in less than an hour of teaching them some basic concepts (try doing that with UML). Another feature is that you can use this for any type of project; you are not locked into a structured or object-oriented mindset like structured analysis or UML. OPM can handle both types of concepts with ease.
Finally, this methodology is fast. It is just easier and more intuitive to model in an OPM fashion. I've also found that others can comprehend the OPM models better than other methodologies too.
I used to be a UML advocate until I found OPM. I have found concepts that are difficult to model in UML are quite easy to model in OPM. It is just more flexible.
The book is really good by the way. It is very complete and gives plenty of good exammples. I congratulate Dov Dori and his team for providing something that all engineering disciplines can use to design their systems.

GIS and Archaeological Site Location Modeling Review

Average Reviews:

(More customer reviews)The list of reasons as to why a computer couldn't predict the location of an archaeological site covers at least a page of small type: we don't know where the water was in those times, we don't know the soil type in those days, we don't know the cultural or social values of the time and how they might have influenced site location.
In spite of this, the advent of ever better GIS software and higher performance computers have lead researchers around the world to being using GIS in a predictive manner to help identify potential sites worth investigating.
This book is a summary of research conducted around the world by people attempting to do just that. GIS can of course be used to map teraine and other features such as springs, both those flowing now and those from the past that have left traces. Combining these data with prediction equasions developed by the researcher have produced some interesting studies that point to success.
The book has a series of contributors from around the world: France, Greece, UK, Slovenia, Australia and of course many different organizations in the U.S. This book represents the state of the art in the field as it is known today.

Although archaeologists are using GIS technology at an accelerating rate, publication of their work has not kept pace. A state-of-the-art exploration the subject, GIS and Archaeological Site Location Modeling pulls together discussions of theory and methodology, scale, data, quantitative methods, and cultural resource management and uses location models and case studies to illustrate these concepts. This book, written by a distinguished group of international authors, reassesses the practice of predictive modeling as it now exists and examines how it has become useful in new ways.
A guide to spatial procedures used in archaeology, the book provides a comprehensive treatment of predictive modeling. It draws together theoretical models and case studies and explains how modeling may be applied to future projects. The book illustrates the various aspects of academic and practical applications of predictive modeling. It also discusses the need to assess the reliability of the results and the implications of reliability assessment on the further development of predictive models.
Of the books available on GIS, some touch on archaeological applications but few cover the topic in such depth. Both up to date and containing case studies from a wide range of geographical locations including Europe, the USA, and Australia, this book sets a baseline for future developments.

Simulation and Event Modeling for Game Developers Review

Average Reviews:

(More customer reviews)This book provides an introduction to some of the basic concepts
involved in using simulation as a part of computer applications and
games. Its content is both conceptual and practical. Conceptually, it
provides extended discussions of some of the theory that might be involved
in simulation design. The theory in part relates to literary and
sociological approaches to cultural criticism, so if you do not do much
reading in this area, you will find the language fairly strange. The
vocabulary goes beyond anything you'll ever find in a standard book on
programming (iconic logic, hermeneutics, phenomenology, and so on). On
a practical level the book provides several MS Studio projects that put
the concepts to use. In most of the chapters it provides extended
discussions of C++ and DirectX, and in this respect it is helpful to
beginning programmers. The last chapter includes a C# project that can
be used for testing games. The testing theory is supported by software
included with SmartDraw.

One of the games included with the book is called Gold Finder. It is a
good start if you want to create a 3-D game. It is complete, so you
can play it and then start modifying it. It includes a 3-D model of a
man. You control the model as it walks around a world and searches for
gold. The book provides a 2-D simulation that shows how a big
retail store can wipe out local economies. If you do not like criticism
of the way corporations do this sort of thing, then you will probably
not like this chapter. The authors don't try to force anything on you,
however. The book also includes a 2-D simulation of a forest fire. The
best thing to do is start with these projects and remake them for
yourself. The authors try to discuss the software in both theoretical
and practical terms so that you can work with it to conceptualize what
you are doing while programming. There are software packages you can
buy to do this sort of thing, but through this approach, you get a chance
to build programs from scratch using Direct X , C++, and C#.

Data Modeling Made Simple: A Practical Guide for Business & Information Technology Professionals Review

Average Reviews:

(More customer reviews)For over a year I'm looking for a good book to help business analysts to understand data models drawn by others and to train them in creating basic data models needed to cover business needs. I found a lot of good books but all too heavy, too many pages, too detailed and very nice if you want to become a real heavy duty data-guru. There is absolutely nothing wrong with data gurus, every organization needs a few of those, but it needs quite a few more of the 'casual' modellers. This book .. not too big.. a good read.. and even better reread.. It contains exactly everything that is needed for those modellers.
So, if you're a Business Analyst, Information Manager and need a good understanding of Data Modelling, even occasionally need to make one yourself, without having to spend years in training: buy this book..

Ever have a bad data day? If you're a business user, architect, analyst, designer or developer, then you've probably had some bad data days. It comes with the territory. Overcoming these problems is much easier if you have an in-depth understanding of the actual data. That's where a data model comes in handy. It's a diagram that uses text and symbols to represent groupings of data, giving you a clear picture of your business and application environment. Data Modeling Made Simple provides the tools you need to read, create and validate models of your business and applications.

This book contains everything about modeling you need to know but were too afraid to ask, such as:
-What are the traditional and nontraditional uses of a data model?
-How do subject area, logical, and physical data models differ?
-When do I build a BSAM, ASAM, or CSAM?
-What is the easiest way to apply normalization?
-Where can I best leverage abstraction?
-How do I decide whether to use denormalization or dimensionality?
-What are primary, foreign, alternate, virtual, and surrogate keys?
-What is the best approach to building the models?
-How can I use the Scorecard system to validate a data model?

Plus over 30 exercises to reinforce concepts and sharpen your skills!

Expert Trading Systems: Modeling Financial Markets with Kernel Regression Review

Average Reviews:

(More customer reviews)The book is actually quite good and Kernel Regression might very well be a good modelling technique. What destroys much of the credibility is that the author is actually the founder of a company that produces KR software. This fact isn't mentioned ANYWHERE in the book. The author just HAPPENS to use a specific software in all his examples. Guess what software? You have to go to the company website to find the connection.
If we set that aside, the book is well written and interesting. Not for the math impaired, though. University level math and statistics needed to be enjoyed in full.

Modeling a Character in 3DS Max, Second Edition (Wordware Game Developer's Library) Review

Average Reviews:

(More customer reviews)I purchased this book after skimming it over in a local store. I wish I had taken a closer look at it. I just came off a 2 week break from work and school. During my break I decided to work on a new model and following along with Mr. Steed's book. This turned out to be frustration hell. The methods in his book are fine if you are into wasting alot of time. Boolean and splines to make a simple character like the one in his book actually doubles your work. You wind up wasting more time cleaning up the errors from following his tutorial. Why he didn't demonstrate the way MOST people in the industry model, which is box modeling, is beyond me. He basicly tries to reinvent the wheel. I found much better tutorials for FREE on the web. Save yourself from learning bad modeling techniques. I happen to also know that Paul Steed DOES NOT model the way presented in the book. This should raise a red flag or two.
