Just keep the big spirit

I doubt that there's a better supplemental DE book out there
I used this book for an introductory differential equations course.With the help of this book, I was completely prepared for everything the professor threw at us and more.

Some of the problems are simple and should help to reinforce the basic concepts learned from another book.Learn the fundamentals from some other book (or even a professor), and refine your thought processes using this one.There are some basic explanations of concepts and problem types, but most of the space is devoted to problems and solutions, as you may have guessed.If I had trouble with a problem from another book, I could almost always find a similar one in the REA book.A few problems are extremely difficult or involved, but the book leads you through every step of every problem.I was blown away by the depth of a few problems, but following the reasoning in this book really helped me to develop a better "feel" for the subject.

Yes, the font looks like something from your mother's typewriter, but the book is very sensibly organized into a (huge) number of chapters that should more than cover any intro-level DE course.My test reviews consisted of working problems from this book and doing little else, and I've never felt more confident going into exams.

If you're willing to put in the time, this book is probably one of the best course-related resources you could ever spend your money on.It would also be a good reference for someone who occasionally wants help with troublesome problem types.

Excellent
This is an excellent supplement to any Differential Equations class.It starts out with easy and straight forward problems and progressively gets to the more advanced problems.All steps are worked out in an easy to understand way.Most importantly this book shows the algebraic steps in obtaining solutions, which is ussually where students have trouble.This book is a must have for any science major.

An Excellent Resource!
If you are studying DEs, get this book! It beats the usual text books that only contain solutions to selected problems, namely the ones that the professor does not assign or examine you on. This book is comprehensive and contains stratagies for attacking the various problems you will encounter in undergraduate DE courses. It even contains problems and solutions to Partial Differential Equations, Fourier Series and Boundary Value Problems, not just ODEs!

Great - after learning hoe to work with - its a life saver

Product Description
Visualizing Magnetic Fields: Numerical Equation Solvers in Action provides a complete description of the theory behind a new technique, a detailed discussion of the ways of solving the equations (including a software visualization of the solution algorithms), the application software itself, and the full source code. Most importantly, there is a succinct, easy-to-follow description of each procedure in the code.

The physicist Michael Faraday said that the study of magnetic lines of force was greatly influential in leading him to formulate many of those concepts that are now so fundamental to our modern world, proving to him their "great utility as well as fertility." Michael Faraday could only visualize these lines in his mind's eye and, even with modern computers to help us, it has been very expensive and time consuming to plot lines of force in magnetic fields.

* Overview of the physics of magnetic fields
* Complete description of the theory behind the new technique
* Overview of the theory of Gaussian elimination and Conjugate Gradient equation solvers (including a software application to visualise the algorithms in action)
* Application software itself, the full-source code and a plain English description of each procedure in the code

Electromagnetism CAN be fun!
This book is a delight! If only it had been available during those less than interesting lectures on electromagnetic theory..........

Here, the reader can simulate almost any combination of magnets, conductors and external fields and visualize the result in a number of different ways. So this book and its accompanying software will find use in grade school, universities and industry. The visual impact of the approach used by John Beeteson should prove inspirational to younger students. I would recommend that any teacher involved in this subject should buy this book and try it out.

I have used the software on a W98 notebook computer and on a powerful dual processor NT machine. It works just fine in both cases.

Review of "Visualising Magnetic Fields"
This book provides a no-nonsense introduction to the ideas and concepts of magnetic field visualisation. Electromagnetics is a large and complex field and, as such, can be difficult to obtain an intuitive grasp of. This book presents the basic ideas of magnetic field analysis in a simple and orderly manner with examples to demonstrate the important fundamental concepts. This makes it an ideal companion for more rigourous texts on the subject that go into greater detail where necessary.

The use of numerical analysis tools is widely regarded as essential for more than the simplest of geometries. Frequently these tools require a substantial knowledge in order to be able to apply them to the problem at hand. With the use of the author's visualisation of numerical solvers in action the user is able to understand how the computation process develops in solving in 2D a mathematical representation of the field problem. This understanding is essential if the reader wishes to progress to the more challenging 3D simulation environment, especially for those creating rather than just applying the simulation software.

Overall I found the book useful as a means of introducing the subject and would recommend it to students in their last year of school or as an introductory text in undergraduate studies. In addition to students of Physics and Electrical Engineering, the underlying concepts covered are similar to those for mechanical analysis (stress, strain, distortion) and computational fluid dynamics, including heat flow problems. Thus students in the other Engineering disciplines will find something useful in the book and especially the accompanying software. ... Read more

Description:
In building simulation, as in several other domains, traditional monolithic simulation codes are still in dominance over simulators based on symbolic equations in a general modeling language. Introduced in 1998, IDA Indoor Climate and Energy has become the first widely spread thermal building performance simulator based on the new technology. Developing a full-fledged dynamic whole-building simulation program is a formidable endeavor in any setting and since the first beta version in 1997 a number of lessons have been learned. The paper shares some of these experiences concerning general program structure, models, performance, integration, GUI design and issues specifically linked to equation-based modeling using a variable timestep differential-algebraic (DAE) solver. ...

Product Description
This is a AIR FORCE INST OF TECH WRIGHT-PATTERSON AFB OH report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A433123. The abstract provided by the Pentagon follows: Concurrent engineering approaches for the disciplines of computational fluid dynamics (CFD) and electromagnetics (CEM) are necessary for designing future high-performance, low-observable aircraft. A characteristic- based finite-volume time-domain (FVTD) computational algorithm, developed for CFD and now applied to CEM, is implemented to analyze the radar cross section (RCS) of two three-dimensional objects, the ogive and cone-sphere. The FVTD formulation implements a Monotone Upstream-Centered Scheme for Conservation Laws (MUSCL) algorithm for the flux evaluation and a Runge-Kutta multi-stage scheme for the time integration. Developmental FVTD work for the thesis focused on algorithm development to analyze scattering and obtain RCS data for closed- surface perfect electric conductor (PEC) 3-D objects using either a Gaussian pulse or sinusoid incident wave. In addition, specification of the direction and polarization of the incident wave gives monostatic and bistatic RCS results. Convergence and threshold checks end the simulation run to ensure accurate computation of the RCS. Validation of the characteristic-based FVTD formulation and code for electromagnetic scattering problems is completed by comparing RCS results obtained from the FVTD code to Moment Method and empirical RCS data. The FVTD results for the ogive and cone-sphere are within 3.0 dB of the MoM results and 3.1 dB of the empirical RCS results. Accurate FVTD computations of diffraction, traveling waves, and creeping waves require a surface grid point density of 15-30 cells/lamda. ... Read more

Description:
The mild slope equation is used to describe wave propagating in the near shore region. In this paper, the finite difference method is used to discretize the governing elliptic equation and the discretized linear equation is solved using GPBiCG (m, n) method. Two cases of wave propagating are used to test the model, and reasonable agreements have been achieved. It is shown that the present algorithm: GPBiCG (m, n) with a flexible and diverse form, has a fast and relatively robust convergence rate, and can be efficiently and economically run in either the linear or nonlinear wave model and easily used to a complicated region. ...

Product Description
With new processorfamilies appearing every few years, it is increasingly harder to achieve high performance rates in sparse matrix computations. This monograph studies new methods for sparse matrix factorizations and applies them efficiently while retaining ease of use of existing solutions. The implementations are timed and analyzed using a commonly accepted set of test matrices. Contemporary processors are used for the tests. The new factorization techniques are proven to be quite competitive with state of the art software. In addition, an optimization effort is applied to an iterative algorithm that stands out for its numerical robustness. This also gives satisfactory results on the tested computing platforms in terms of performance improvement. The same set of test matrices is used to enable an easy comparison between both investigated techniques, even though they are customarily treated separately in the literature. Possible extensions of the presented work range from easily conceivable merging with existing solutions to rather more evolved schemes dependent on hard to predict progress in theoretical and algorithmic research. ...
