Applications Books

It is great for teaching class on the basics of MS ACCESS.

Each chapter is a Project. Project 1 took you through what you should already know about other Windows applications. I felt that I would not be trying to learn Access if I did not know how to use "Help" in other Windows applications.

Anyway, this was a great BASIC Access book. I did, however, have to send an email to Prentice Hall. After a week, I still have not heard from them. There are sections in the book called, "Discovery Zone Exercises". They let you figure out what to do by using "Help". Sometimes "Help" is no "Help". My advice to you is, if you can not figure out the "Zone" exercises just go on. I found one answer in the "Intermediate" book. Another at a book store.

With all that, the book is well written. They have you do the same thing more than once and sometimes in different ways. It earns 5 star's.

I am now starting on the "essentials Access 2000 intermediate" book. Look for that review.

I bought all three book, beginning, intermediate & advanced to use in a course that I teach in Theories of Database. My students used these books to learn Access on their own. The book is very clear with practical examples. It includes many hints and tips that help avoid many of the pitfalls that beginners will typically encounter. Gives plenty of assignments and examples. My only complaint in that the binding on the spiral addition is pretty flimsy. I highly recommend this book for beginners or for teachers looking for a good access "workbook".

Great way to learn Access basics. Interesting examples, lots of stuff to help you along, plus neat tips and pitfalls. Good CD for practice.

This book is compatible for Access 2007 and 2003(title of book doesn't let you know that), what it does is answer questions that the author poses. Many of these scenarios are relevant. I have never bought an o'reilly cookbook previously, but this book is very refreshing especially when you look at the current books out there. This book isn't for new people, this book is for people who want real solutions to the problems that they might face. If your looking for a first book to get a real grasp of access, get Access 2007 Inside and Out, if your someone who has read a book or two, or has some experience but still runs into hurdles in data manipulation, get this book.

Any involved in database management in general and Access in particular will want the ACCESS DATA ANALYSIS COOKBOOK, a survey which shows how to solve common problems of extracting data and performing calculations from large databases. From developing better queries and applying them to inserting, updating and deleting data to managing text-based data and using arrays, this offers a wealth of high-level technical Access information perfect for managers who already have the basics down.

I am not sure if this was the intention of the authors, but I find this book to be amazingly helpful given my set of circumstances: I am pretty skilled in Excel and very new to Access, and I want to use Access in the same way I use Excel, but with much larger quantities of data. Of all the Access books I have been referencing, this one is by far the most useful. It provides lots of information on SQL if you are interested, but I'm ignoring that for now and still the book is great at providing the answers I need. I suspect there are lots of people in my shoes (heavy Excel background, but little experience with Access) and so I want to let you know about this excellent reference. I hope it helps you as much as it is helping me!

To be more specific, if you are skilled at constructing formulas in Excel to convert and reformat and analyze data, and you have at least a rudimentary understanding of Access (I have attended a few 2-hour workshops and that's all), and you find yourself stumped in terms of how to do something in Access that would be easy for you to do in Excel, but you can't do it in Excel because you have millions of rows of data, then I'm guessing you will love this book.

This book is not about designing forms, primary keys, or the use of built-in wizards to make easy queries or reports. This book is about applying Access to real-world business problems. The book addresses how to query data, how to move data to and from Access in various ways, the calculation of different financial and investment terms, and other such problems. The reader of this book should already have some Access experience and thus know how to get around the Access user interface, know basic table structures and relations among them, and how to construct simple queries. As long as you know this much or more, the book should be quite useful to anyone interested in business solutions using Access to analyze the data that is involved. The book consists of a series of recipes that provide example queries, programming tips, and also some requisite math. The following is a summary of each chapter's contents. Each section of each chapter is actually a recipe consisting of a problem - the section title - and its solution(s).

One final word of advise is to purchase "Head First SQL" or some other good book on SQL if you don't already feel proficient. Although the book briefly explains each query it shows, I don't think the explanation is sufficient unless you see the stuff every day. A good thing about the book is that it shows screenshots of the application in just about every recipe and usually gives directions in clear numbered steps.

Farhang-Borjeny does a superb job explaining complex topics in a very straightforward fashion.

As a course instructor, I found adaptive filters a very helpful book for teaching. It is also an easy to read book, as a self-study. Having used the previous books in the market, I found this a lot easier to teach. My students seem to understand much better. The very nicely designed end of the chapter problems are very helpful in enhancing the students understanding of the basic concepts. Farhang-Boroujeny has a very special view towards the fundamental concept of convergence; the significance of the power spectrum of filter input on convergence behavior. He starts injecting this concept right from the chapter on Wiener filters and carry this through out the book. Chapters 6 and 12, giving the basic concepts of LMS and least squares, are really nice and very instructive. Chapter 7 is very enlightening in understanding the basic concepts of the convergence and its relationship with the power spectrum of filter input. Chapter 8 has made the difficult topic of frequency domain adaptive filters very easy to follow. It also contains some unpublished work which I found very interesting. Other chapters also bring to the attention new views of adaptive filters. I am sure that the students and new researchers enjoy this book and will learn all important concepts of the adaptive systems and filters from this very well written book.

Congratulations to Dr. B Farhang-Boroujeny!

This book is one of the best books on the subject! The writing style is as clear as Widrow's "Adaptive Signal Processing" and it has as much detail as Haykin's "Adaptive Filter Theory". In short, if you have to get ONE book on the subject, this is the book to get. Perfect for either studying on your own or learning in a classroom setting, and relevant to both researchers and practicing engineers.

Superb, great book! . Starts with simple theory, it makes you think harder and harder and you progress into the deep science of adaptive signal processing and the implementation of filters with different algorithms, difficult themes are made easy and over all this is great reference book for the designer. I wish I could get a solution manual for a deeper and more reliable analysis. It will serve you well is you use Matlab to analyze and simulate complete Adaptive filters for equalization or so.

Perhaps the most pertinent question answered by the book is what are the differences between Elements 2 and 3. If you are an existing E2 user, is there enough incentive to migrate to E3? Huss devotes considerable space to squarely address your concerns.Of the changes, the most useful is Photo Organizer. A huge improvement over File Browser, which is what E2 gave you. PO is well suited for collections of hundreds or thousands of photos. Many people who take photos regularly will run into the scaling constraints of File Browser. PO lets you attach metadata to a photo, in the form of keywords which you can choose as succinct descriptors of the photo. Then, later, if you search for a keyword, PO will return a set of thumbnails of the photos with that metadatum. Picking a thumbnail gives the original image. Very simple to use.If you know HTML, the metadata in PO maps to the <meta> tag that can be used in any HTML page.

Serious collectors should welcome PO. The only drawback is that it does not exist in the Mac version of E3; only in the Microsoft version. Huss speculates that Apple's iPhoto is too close in functionality for Adobe to economically develop a Mac version.

What a great book! What separates this book from all the others is the downloaded pictures that you work with as you make your way through the book. I kept the pictures in their chapter folders and put them in a folder called Elements 3: 50 Cool Ways. Then after practicing with them, when Adobe asked me if I wanted to save changes, I said no - so I could practice again and again. I must be slow because I have needed to practice them again. Thanks Dave, for a wonderful book. Will you be doing the same for Elements 4?

This book is not only a pleasure to read, it also was superbly reproduced and technically accurate (not all books are!). Dave Huss goes the extra mile to provide an excellent selection of real world (read: useful) tutorials that cover in detail how to retouch and correct common digital photography problems (color cast, wrinkle removal, panorama assembly, red eye, perspective correction). It also covers common challenges associated with managing digital photo libraries (album assembly, photo cataloging, image management). The photo projects are perfect for newcomers to digital photography (like me) and expose many of the features of Photoshop Elements I needed to get up to speed on fast. Well worth the investment.

This is the most user friendly book that I have ever held in my hands. The great thing about this book is that Dave works with you one on one by having you download the pictures that are the examples in the book! This way you work on the same picture step by step and you can see what your picture should look like through the edit process. This book is very FUN and INFORMATIONAL! Buy it you won't be sorry!!! And you will do things with this program that you didn't know you personally could do!!!

This product is the same book I have been using for the past two years. This book is as good as the last two I received. The problem is with the people who send the books. The last vendor took three weeks to mail the book, then the US Mail took 18 days to carry it from California to east Alabama. It took five days to carry it from Atlanta to me. This is disgraceful.

Recieved item on time, right when we were told it would arrive. Book in very good condition.

Fine transaction. Item arrived quickly and was as described. Would recommend this seller.

I think this is a great algebra 1 textbook. It covers alot of needs and has odd-numbered problem answers in the back of the textbook.
It has examples, etc.

If you're trying to learn about amino acids this book is a good place to start. At just over 100 pages it's a bit short. For instance, the amino acid serine is covered in seven lines. It's also approaching 20 years old. Having said that it still provides a lot of useful info. And combined with "The Amino Revolution" by Robert Erdmann, PH.D., it can give you a pretty good idea of the potential benefits of amino acid supplementation. There's so much more to learn on this topic and I'm still waiting for the definitive amino acid book. Unfortunately, most doctors don't have a clue.

Though this book is older, it has a lot of good information, especially for people wanting to learn about using amino acids to treat illness. I like it better than Amino Revolution. Its a quick read- short, but fully detailed.

leon chaitow show in this book the healing benefits of every amino acid that is known and the illnesses that they are capabale of healing, and they are very much capable. he also writes a word of caution to specific illnesses wich medicines are not allowed to combined together and in the wright dosages.many biochemical explanations on the amino acids of how they work in diseases are explained in a very readable way for everyone and the all book in general is enlightning.very recommanded!

This excellent book is a valuable guide to the therapeutic use of amino acids. It explains how amino acids function as the building blocks of protein, and lists the metabolic paths of the amino acids, the qualities of the individual amino acids and the disease states in which amino therapy can be helpful.

The author discusses the essential aminos (that the body needs to get from food) and the non-essential ones (that are made in the body), and how these relate and interact with one another. The co-factors (vitamins, minerals and trace elements) of the individual amino acids are covered in detail.

The author provides valuable information on the therapeutic application of amino acid therapy, including a summary of therapeutic dosages and cautions. Some of the uses include treatment of depression (DL-Phenylalanine, L-Tyrosine), insomnia (Tryptophan), cold sores (L-Lycine), detoxification (L-Cysteine, Glutathione) and wound healing (L-Arginine and L-Glutamine).

An appendix provides the amino acid content of certain common foods (besides meat, other excellent sources are eggs, milk, yoghurt and chocolate). The book also provides the contact details of various organisations and contains a thorough index. I also recommend he Amino Revolution by Robert Erdmann and Meirion Jones.

If you only read one book about case research, buy this one together with R. K. Yin, Case Studie Research: Design and Methods (Beverly Hills, CA: Sage, 2002).

I am working on my theses of doctoral grade and found this book very useful for my methodological work.

Everyone is telling stories through case studies but what do they mean. How can you tell a good case from a poor one? Yin does something that few people have done -- provide a strong academic explaination that is understandable to the business person. Too often strong academic concepts are explained in language that makes the less appealing and seem weak to business people.

Yin's examination of the different types of case studies and study methods helps people understand what they are reading when the read a case study.

This very accessible book is a must for researchers and those who want to understand what cases are and how to use them.

This book is a real good complement to the classic "Case Study Research" from the same author. Some of the concepts of the other book were not aboslutely clear (although the book is very good), but I was really able to understand fully after reading this one. Don't buy one without the other!!! These two books have everything you really need to know about case studies. Good luck!!

I, too, took the full-year course with Prof. Holland while he was editing the book. I also took a graduate Complex Analysis course with him a year later. It is no coincidence that it is in these areas - orthogonal functions, PDE solutions in various coordinate sustems, and complex analysis - in which I consider myself an expert to this day.

Prof. Holland teaching style is mirrored in this book. The problems are numerous. He stresses the same key points throught the chapters. You practice, and you are continually reminded. If you have had the priviledge to be taught by Prof. Holland, and you keep up, you must retain the information.

What amazes me to this day is that the famous Prof. Richard Feynman avoided teaching this material to his undergraduates at Caltech. (See his Lectures in Physics, III.) Yet, Prof. Holland managed to teach this to a bunch of sophomores and juniors at the Univ. of Massachusetts to a very high degree of success by knowing what was inportant in physics, and what could be saved for later.

This text cannot be recommended highly enough.

I had the pleasure (challenge?) of taking Prof Holland's one year sequence of courses on Hilbert Space theory at the University of Massachusetts while he was editing this book. I agree with the previous review that the flow of the text, the problems and the descriptions of the concepts are well thought out and enabled me to grasp a rather difficult concept. The two main applications given in the text are heat transfer and, of course, Schroedinger's equation. In the case of heat transfer for instance, a number of different boundary conditions are presented to the student along with different geometries and analysis (Bessel, Fourier, etc).

If you like the problems in the text I can assure you that I crunched through all of them personally!

It's unusual for a book on this topic to be targeted at undergraduates. What's even more unusual is that the author succeeds in explaining differential operators at this level. I found the discussions on the Legendre and Hermite operators especially illuminating. There are numerous worked examples and exercises. The real accomplishment of this text is that the author has managed to select results that are of crucial importance, omitting some important theorems along the way, but maintaining the core idea. That is a difficult trick.

This book is for a one year course on functional analysis. It would replace a traditional course course on mathematical physics with advantage.The first two chapters are on ordinary differential equations. They are very good.The third chapter is on Hilbert spaces beggining with the vibrating string , fourier series , etc, thus motivating the last section on Hilbert Spaces.The fourth chapter is on eigenvalues and eigenfunctions of second order differential operators The remaining of the book covers the Schrodinger equation in one dimension , Bessel's Fuctions , Eigenfunctions of the Laplacian and the Fourier transform .The book explain difficult concepts in simple terms. Things like Lebesque integral,Absolutely continuos functions, etc Everything is carefully explained.Let me quote this passage on page 419: "The elements of this Hilbert Space are functions of two variables.The Hilbert spaces we considered in earlier chapters consisted in functions of one variable. Does this confuses us? Not us!"In fact the book is almost perfect

This is a very practical quantum mechanics book. It tells you how to use quntum mechanics in many practical engineering situations. The worked problems at the end of each chapter help to enliven and reenforce the learning experience. The chapters on quantum tunneling is especially good. This book is suitable for students studying applied physics, materials science, electrical, electronic, mechanical engineering.

This book is an excelent introduction of quantum mechanics for engineers and non-physicists.

Levi's book differs from standard QM texts, in furnishing more of an applied bent. Directed towards those students in applied physics, materials science and engineering. For example, there is a superb chapter on electron propagation in crystals. Where we see how to describe propagation by transmission matrices. And how energy bands arise due to the periodicity of the potential seen by electrons. Of course, solid state texts also discuss this. But the treatment here of such ideas as tunnelling, and using the WKB approximation to describe that tunnelling in a semiquantitative manner, is clear and detailed. Plus, the examples focus on important heterostructures, where band gap engineering is important.

For semiconductor lasers, there is a similar treatment. With comparisons amongst the common types of laser diodes, like GaAs and InGaAsP.

The numerous problems and the copiously worked out examples are also a nice feature of the text.

There is no shortage of quantum mechanics text to choose from. And if I had solely relied on the majority recommendations for an introductory text, I would have certainly missed this gem.

The author is very successful presenting the recondite fundamentals of quantum mechanics in a manner accessible to material scientists and engineers. This is accomplished without losing the rigor necessary to build a strong foundation. Applications of concepts are dispersed through out the chapters and keep the reader's attention.

But by the far the best selling point of this book are the worked problems at the end of the chapters. It is my personal opinion that if a textbook fails to at least provide final answers and solution hints to presented exercises, it is not really a textbook, but a reference reserved for those who have been adequately exposed to the material before. Here all end of the chapter questions are accompanied with worked solutions. This is a rarity among all undergrad or graduate science or engineering texts. This alone makes it valuable for self-study.

To those completely uninitiated to quantum mechanics, I do not recommend this book as a sole source because it is not sufficiently self-contained. It would be best to complement it with "Introduction to Applied Quantum and Statistical Mechanics" by Hagelstein. I have yet to read "Applied Quantum Mechanics" by Kroemer, which has recieved much praise and appears to be another excellent introductory source.

This handbook is a collection of ideas from companies for designing employee training and learning systems. It covers such areas such as creating the "learning organization", outsourcing, electronic performance systems, interactive multimedia training systems, diversity training and development, training for global operations and benchmarking for best practices.

This comprehensive handbook helps trainers design classrooms, self-study and computer and web based training programs. While delivering the latest information on how adults learn best, it shows trainers how to prepare lesson plans, create visual aids, and deliver dynamic and powerful presentations.

This is a great resource for HR professionals from tiny to mega corporations. Contributing authors are the most respected experts in their fields. Primary focus is on training and development: accountability, justifying programs, format, leadership, pros, cons, pitfalls, challenges . . . all aspects are covered.

As I research and write my Adult Education thesis, this book is the most useful tool I've found.

The ASTD Training and Development Handbook, Fourth Edition, by Robert L. Craig, is an essential reference book for faculty, teachers, educators, and learning system administartors at all levels including University, Corporate, K-12, and Community Colleges. It is easy to use, very comprehensive, and has great quick summaries. With the fusion of the teaching, training, and tutoring into a learner centered model this book is more useful than ever. A MUST BUY. The price is worth every penny.

The Handbook is arranged to cover almost all aspects of Training & Development. The topics are carefully selected and their authors picked from among the top names in their respective fields and therefore, the chapters are focused, targeted and provide the right mix of information and practical guidelines.

Each chapter addresses a single topic (like corporate universities, customer service training, leadership development, etc.) and is written in a straight-forward manner at the right depth making them easy to read and the perfect introduction to the topic without losing it's functionality as a reference.

No T&D professional should go without this book whether as a reference and a quick source of information when memory will just not oblige or an informative and valuable resource for information and ideas.

The Handbook is divided into 5 Sections:
1) The Training & development Function - Covering such topics as the learning organization, history of training and cost accounting for training.
2) Program Design & Development - The chapters on ISD; HPT; Adult Learning; & Evaluation are brilliantly written. I keep on going back to them again and again.
3) Media & methods - Includes some good case studies as well as Thiagi's excellent chapter on instructional games.
4) Training Applications - This is a brilliant discussion of almost all training topics that you might come across.
5) Resources - While these might be a little dated, they are still quite useful.

Check the table of Contents and some of the samples in the pages so obligingly provided by Amazon.com and don't be deterred by the length or the price of the book. This book is worth every cent and will last you long after you have forgotten the cost.
