A great introduction to control theory.However, it would help if you know something about differential equations. I read Ogata's book on control (over 900 pages) from cover to cover twice and still could not figure out exactly what state variables are. This book explains things very well but you do need to do the problems at the end of each chapter. The use of "free-body" diagrams is a great idea.Ogata's book is great for explaining a lot of the details but this book explains the important things in a concise but easy to understand manner. I now finally understand how to draw a system diagram by starting from the inputs for each separate system. Everything is brought together -- system diagrams,transfer functions,state variables,the purpose for LaPlace transforms,and input-output models. This is not a book about control theory and it is covered in only the last two chapters but if you are taking, or going to take, a course in control theory,read this book first. It will save you a lot of frustration and bewilderment.

This textbook is ideal for an undergraduate course in Engineering System Dynamics and Controls. It is intended to provide the reader with a thorough understanding of the process of creating mathematical (and computer-based) models of physical systems. The material is restricted to lumped parameter models, which are those models in which time is the only independent variable. It assumes a basic knowledge of engineering mechanics and ordinary differential equations. The new edition has expanded topical coverage and many more new examples and exercises.

Eclipse Modeling Project: A Domain-Specific Language (DSL) Toolkit Review

Eclipse Modeling Project: A Domain-Specific Language (DSL) Toolkit
Average Reviews:

(More customer reviews)
I need to give a bit of balance to the previous reviews. I basically like the book, but it is a mixed bag and could be a lot better in certain areas. If you expect a start to finish tutorial, you will be disappointed because some background material is presented out of order and you really should read some of his cited references beforehand. For example he discusses the dynamic instance capability in EMF using a mindmap DSL, but doesn't introduce the mindmap DSL itself, until a little later. Also, it will help to have some familiarity with EMF as the coverage in chapter 3 can be followed but is a bit thin and EMF and ecore are purposefully not intended to duplicate the EMF book. The book's usefulness to you will depend upon where you are in MDD and how you want to use MDD and DSLs. The eclipse modeling project is and will undergo rapid change and this book appears somewhat rushed and rough in spots. His second edition when it comes out should be really better organizationally as the Eclipse Modeling projects mature. For example,Chapter 5 on Xtext and TCS is basically a mild description with no example content because that area was not mature at publication. The examples in Chapter 14 on the Xpand template language are in my view a bit skimpy and simplistic for folks wanting to do serious scripting. Similarly if you want to learn QVT, section 13.6 on library operations provides syntax but little to no examples, but the discussion in section 13.5.3 on the shorthand notation used in imperative iterate expressions is really helpful in understanding QVT syntax in the examples presented elsewhere in the book--like chapter 6. Therefore to get the most out of this book, you will be hopping around and be doing multiple reads and passes until it makes sense to you. Don't give up. Do buy the book if you're interested in MDD and DSLs. Gronback has done a nice job developing a mindmap and requirements DSLs that he uses in chapter 6 on model to model transformations. Although you'll need to get comfortable with the QVT and OCL, try running the examples yourself--typing them in to get used to the syntax. His view of MDA at Eclipse in Appendix B is spot on accurate, and I hope OMG takes his advice. If you are interested in graphical model development for your DSL, then Gronback offers strong support for that in Chapter 4 and Chapters 9 through 12. This is no surprise as Gronback is the project lead for GMF. However if you are interested in model to model transformations, QVT, and model to text, and OCL you will be disappointed if you are a beginner requiring step-by-step explanations of the QVT code. Also, don't give up when you reach section 3.2.4 on applying OCL. If you're new to OCL and ecore Eannotations, this will be a rough spot. Finally if you're put off by the price, I'd recommend taking a look at downloading all the OpenArchitectureware tutorials. They are a little stale wrt the later Eclipse Modeling releases, but still helpful and free!

Computational science is a quickly emerging field at the intersection of the sciences, computer science, and mathematics because much scientific investigation now involves computing as well as theory and experiment. However, limited educational materials exist in this field. Introduction to Computational Science fills this void with a flexible, readable textbook that assumes only a background in high school algebra and enables instructors to follow tailored pathways through the material. It is the first textbook designed specifically for an introductory course in the computational science and engineering curriculum.

The text embraces two major approaches to computational science problems: System dynamics models with their global views of major systems that change with time; and cellular automaton simulations with their local views of how individuals affect individuals. While the text is generic, an extensive author-generated Web-site contains tutorials and files in a variety of software packages to accompany the text.

(More customer reviews)

If you're a working stiff now, but you were a student as I was, who sent stuff "down the memory hole," only to discover years later that you really needed to DO simulation--AARGHH!!!--then Law and Kelton's book is what you'll need close at hand.
The coverage is complete, including basic materialon input probability distributions; random number generatorsand testing (most useful for students); and output data analysis. Solid, more practice-oriented chapters cover variance reduction, experimental design (could borrowmore from Kleijnen's work), and software. A final chaptergives an in-depth approach to manufacturing simulation.
Unfortunately, some material is dated. For example,the software chapter addresses SIMAN/Cinema, whichSystems Modeling Corporation has (thankfully!) replaced with ARENA (though SIMAN is still the basic simulationlanguage). The book gives overviews of several simulation modeling languages; practitioners doingtrade studies choosing "the corporate simulation tool" will be grateful for this ecumenicism.
The chapter covering validation and verification could afford to borrow more from currentsoftware engineering practice. Also, simulation modelingapproaches for network computing and communicationswould comprise a good extra chapter (Law gives a shortcourse on the subject).
Law and Kelton isn't light reading, but it's not a dryhandbook, either. If you've had some light programmingexperience and vaguely recall your stats class, you'll findit approachable.
But this book is mostly the timeless stuff you'll need toget your work done. With the recent proliferation of inexpensive simulation software, companies are thrustingsimulation work on engineers and system/software analysts who have little or no training. They should keepand use Law and Kelton's book, which provides both good skills and a roadmap to laying out and finishing a simulation project.
But I give Law and Kelton's book one of my highest compliments: Expensive technical books

I enjoyed reading this book. The tone was light and the same detailed real-world style examples continued throughout the book. The four types of business models covered were explained simply and clearly. Using the example diagrams, I have begun to create my own business models. Having done business and technical modeling on and off since 1991, this book was a great introduction to some new types of models, the emerging standards, and some excellent tips on techniques for activities that take place around the models such as workshops and simulation. I appreciated the non-technical way that the models were presented, such that both a business-person and a hard-core techie could both get value from the same model. The authors' website promises to provide more details, including updates on tools, and they have been kind in helping me to identify some available tools that might fit my needs.
I am certainly in a better position to incorporate business models into my new and existing business ventures from studying this book.

Theory of Modeling and Simulation, Second Edition Review

Theory of Modeling and Simulation, Second Edition
Average Reviews:

(More customer reviews)
The first edition of this book appeared in 1976 and had only one main author, Bernard P. Zeigler, who authored other appreciated classic text books. The first edition was already a must read for the simulation community, which has been asking for an updating. The new edition is not just a re-edition with small corrections. The advances in simulation and modelling techniques helped to design a really new edition, necessary to meet the need for a theoretical foundation. Bernie Zeigler developed a unifying formalism DEVS (Discrete Event System Specification). With DEVS it is not only possible to specify discrete event systems; it is also particularly suited to integrate both continuous and discrete paradigms for modelling and simulation (discrete time & differential equations). DEVS features are also present in the systems theory.
The first theme of this book is to propose a sound methodology for the construction of complex system models based on the unifying concept of the DEVS Bus. This concept enables the mapping into DEVS of different models expressed in various formalisms such as Petri nets, Hierarchical block diagrams, cellular automata. The second theme focuses on parallel and distributed simulation of discrete event models. Distributed simulation has the potential to support the co-existence of multiple formalisms in multimodels.
I will try to depict the merits and demerits in comparison to other current and past books. First of all, being in the simulation field for ten years now, I have to cite some complementary references. Without giving an exhaustive list of all recent valuable books in the simulation field, we can find other high quality simulation text books ; for instance for continuous simulation [Cellier 1991], for general purpose simulation [Fishwick 1995] or even for more specific object-oriented simulations [Hill 1996]. However, I must admit that this Theory of Modelling and Simulation¡¨ is the only book available to help construct efficient object-oriented simulations of DEVS models on parallel and distributed environments. In addition, modelers who have to deal with HLA (High Level Architecture) compliant simulations will find in the book the reference to design integrative simulations.
The best significant features of this book are:
*The presentation of a comprehensive framework for continuous and discrete event modelling and simulation The exploration of the mathematical foundation of simulation modelling.
*The discussion of system morphisms for model abstraction and simplification *The presentation of a new approach to discrete event simulation of continuous processes. *The discussion of model credibility and interoperation * The highlighting of design concepts like such as modular and hierarchical model composition. *The presentation of a sound methodology to achieve parallel and distributed simulation models.
The reviewer only regrets the lack of public availability for DEVS platforms, despite the quotation of a web site, simulation environments (such as DEVSJAVA) are a real need to fully understand practical and theoretical aspects.
This book has multiple facets. From my teaching and scientific experience, I would say that the primary audience comprises engineers, scientists and other technical people working in academic institutions, but there are many chapters particularly well suited for students at a graduate or even undergraduate level. In my opinion, this was not the case of a previous book from the main author [Zeigler 1990] which was an excellent reference for specialists. I am now impressed by this ability to communicate at various levels. I strongly recommend this book for the reader interested in any kind of simulation and modelling, its impact on research in control will surely be recognized.

Tutorial on Neural Systems Modeling Review

Tutorial on Neural Systems Modeling
Average Reviews:

(More customer reviews)
We used this book for the upper-level undergraduate students in an interdisciplinary computational neuroscience course at a small liberal arts college. This is a fine, well-written book. One of the strengths of this book is that it starts with very basic programming in Matlab, so that the students without programming backgrounds can easily follow along. The programs in the book are well commented, and they progress slowly and logically in complexity. More advanced math topics are well separated out in Math Boxes. The examples of the neural systems are covered in enough (but not too much) details to be interesting and accessible to the readers. The book is definitely considerate of and sensitive to the wonderfully interdisciplinary nature of this field, so that the materials can be digested by people with different backgrounds. One can not contain all the topics in computational neuroscience in a single book, but this book does a great job of covering many important and interesting ideas/areas (Hebbian learning, Hopfield model, lateral inhibition, adaptation, supervised and unsupervised learning, etc.).
It works very well as an introductory textbook (or tutorial) of the field. The codes and the discussions are clear and simple (not intended as an advanced textbook), and to me, that's the strength and unique quality of this book.
By the way, most of the computer programs listed in the book work well with Octave (as well as Matlab).

Neural systems models are elegant conceptual tools that provide satisfying insight into brain function. The goal of this new book is to make these tools accessible. It is written specifically for students in neuroscience, cognitive science, and related areas who want to learn about neural systems modeling but lack extensive background in mathematics and computer programming.The book opens with an introduction to computer programming. Each of twelve subsequent chapters presents a different modeling paradigm by describing its basic structure and showing how it can be applied in understanding brain function. The text guides the reader through short, simple computer programs printed in the book and available by download at the companion website that implement the paradigms and simulate real neural systems. Motivation for the simulations is provided in the form of a narrative that places specific aspects of neural system behavior in the context of more general brain function. The narrative integrates instruction for using the programs with description of neural system function, and readers can actively experience the fun and excitement of doing the simulations themselves. Designed as a hands-on tutorial for students, this book also serves instructors as both a teaching tool and a source of examples and exercises that provide convenient starting points for more in-depth exploration of topics of their own specific interest.The distinguishing pedagogical feature of this book is its computer programs, written in MATLAB, that help readers develop basic skill in the area of neural systems modeling. (All of the program files are available online via the book s companion website. Actual data on real neural systems is presented in the book for comparison with the results of the simulations. Also included are asides ( Math Boxes ) that present mathematical material that is relevant but not essential to running the programs. Exercises and references at the end of each chapter invite readers to explore each topic area on their own.

In this book you'll find, fully explained, subjects that are only mentioned briefly in other texts on modeling. I liked the chapter (chapter five) on Eigenvalue Methods for the analysis of dynamic models. I wished I had it four years ago when I was taking a course on modeling at the University of Washington. It really shows you how to do it. The same can be said about chapters 2 and 3 on optimization and chapters 7 and 8 on probability models (I liked specially the one on Markov Chains). I'm using it for teaching those techniques. The pseuodocode it includes is particularly helpful when you take the methods presented in the book to the computer. However, I would not recomend it to be used on its own as the only text in a course. It is a nice complement to texts like Gurney and Nisbet's Ecological Dynamics that presents many particular models in detail, while Meerschaert makes enphasis on general techniques. It's also a step up the ladder from "abc-of-modeling-techniques" texts like Vandermeer's Elementary Mathemathical Ecology. With 20/20 hindsight, if I had to learn modeling from the begining (or, if I had to teach it as I'm doing now) I would choose these titles as a step-by-step system, coupled with some Math packages like MathCad or Matlab.

Mathematical Modeling 3e is a general introduction to an increasingly crucial topic for today's mathematicians. Unlike textbooks focused on one kind of mathematical model, this book covers the broad spectrum of modeling problems, from optimization to dynamical systems to stochastic processes. Mathematical modeling is the link between mathematics and the rest of the world. Meerschaert shows how to refine a question, phrasing it in precise mathematical terms. Then he encourages students to reverse the process, translating the mathematical solution back into a comprehensible, useful answer to the original question. This textbook mirrors the process professionals must follow in solving complex problems.Each chapter in this book is followed by a set of challenging exercises. These exercises require significant effort on the part of the student, as well as a certain amount of creativity. Meerschaert did not invent the problems in this book--they are real problems, not designed to illustrate the use of any particular mathematical technique. Meerschaert's emphasis on principles and general techniques offers students the mathematical background they need to model problems in a wide range of disciplines.This new edition will be accompanied by expanded and enhanced on-line support for instructors. MATLAB material will be added to complement existing support for Maple, Mathematica, and other software packages, and the solutions manual will be provided both in hard copy and on the web. * Increased support for instructors, including MATLAB material as well as other on-line resources* New sections on time series analysis and diffusion models* Additional problems with international focus such as whale and dolphin populations, plus updated optimization problems

...for anyone interested in the history and development of Population Biology. It is a real shame that this book has gone out of print (and that Kingsland hasn't chosen to do a second edition)as this relatively short (267pp) book captured the really important trends and ideas of mathematical ecology up to the early 1970's in straight-forward and remarkably non-technical language. Kingsland gives us both the theories and the background and personalities that generated the theories, along with some delightful portraits of the Heavy Hitters during this seminal period in theoretical ecology. She ends with MacArthur & one would like to think that enough has happened since then that a sequel is in order, but I would recommend this book to any advanced undergrad or first-year grad student looking for background material.

The first history of population ecology traces two generations of science and scientists from the opening of the twentieth century through 1970. Kingsland chronicles the careers of key figures and the field's theoretical, empirical, and institutional development, with special attention to tensions between the descriptive studies of field biologists and later mathematical models. This second edition includes a new afterword that brings the book up to date, with special attention to the rise of "the new natural history" and debates about ecology's future as a large-scale scientific enterprise.

"Use Case Driven Object Modeling with UML, A Practical Approach" is perhaps the best book on the market for a down-to-earth, hands-on introduction to the Unified Process.

1. "The Approach in a Nutshell" as well as constant reference back to it.
2. The lists of ten.
3. The chapter on "robustness analysis" showing the transition from analysis to design (always a difficult transition in any methodology). This is the best part of the book in my opinion. It was real "hands-on".
"The Approach in a Nutshell" gives a great overview of the process including milestones, and provides a framework for everything to fit into. As the reader progresses through the book, each chapter summarizes that part of "the approach in a nutshell" that the chapter fits into. If this was the only feature in the book, it would be worth the price.
If you have ever read another series with "lists of ten", these are better. The lists of ten (there are over half-a-dozen) are worth taping up on the walls. They reflect the experience of someone who has been there and done that. The lists of ten alone are worth the price of the book.
The transition from analysis to design has rather heavy focus in this book, and deservedly so. Going from analysis to design is tricky in any methodology, and "Use Case Driven Object Modeling with UML, A Practical Approach" shines in this area. The authors refer to this as "robustness analysis," and this section alone is worth the price of the book.
This won't be the only book concerning the Unified Process that you will ever buy. But it is more than likely going to be one of the most useful to you.
This is not a tutorial on the UML; purchase "UML Distilled, Second Edition" by Martin Fowler and Kendall Scott if that is what you are looking for. The title may be slightly misleading in this respect. The real focus is on the "Practical Approach" part. If you are trying to sort out HOW TO DO IT, then this is a necessary addition to your library. It won't replace your books on the UML or the Unified Process, but it will help you pull it all together into a cohesive whole so you can get a grasp on how to start and how to proceed.
In addition to being very informative and clear in direction, the book is also surprisingly interesting to read. Its clarity and brevity keep it simple. You won't get bogged down reading this one. It is very well written.
