There are six pre-cut stencils in this sturdy little book from Dover. The pages are easy to remove, very durable, and clearly labeled. The designs themselves are great, bold and fascinating. I used them on a set of jars I had, and they came out beautifully. They make exotic containers for my collection of beads and marbles. The designs included are arctodus (a bear), smilodon (the sabre-tooth cat), mammuthus primigenius (a wooly mammoth), pilohippus (a type of horse), andrewsarchus (a type of wolf), and archaeotherium (which resembles a boar).

This sturdy little book has six different precut shell stencils. They're all printed on durable, easy-to-remove, pages. I used them to cut out shapes from pre-flattened sponges, and to make templates with contact paper so that I could etch some of the designs on a bathroom mirror. I'm also going to paint the shells on some larger bars of soap I have, or I might even use them to make decorative tiles. These shells are beautiful, and you'll come up with dozens of your own ideas for using them. Included are a chambered nautilus, an imperial wentletrap, a violet spider conch, a fighting stromb, an Atlantic bay scallop, and a vexillate volute.

This book contains six sturdy pre-cut stencils of swampland animals. Each pattern is strongly outlined in just a few parts, providing a bold design of the creatures. I used these to make a big swampland mural-style poster, but there are dozens of things you can use them for, including putting designs on walls, windows, cards, or anywhere else. The animals in this book are an alligator, a dragonfly, a black skimmer bird, a diamond-back terrapin, a muskrat, and a spring peeper frog.

There are six train car stencils here, cut into heavy laminated paper. All are disconnected stencils, having separations between elements; I think this style is particularly effective in wall or furniture stencilling. The specific stencils are: an engine (approximately 2 inches high and 4 inches long), a passenger car (5 inches long and 2 high), a boxcar (5 by 2), a coal car, or tender (2.5 by 1.5), a flatcar (5 by 1), and a caboose (4 by 2). The engine is pictured on the cover. Connections between the cars DO line up with each other. They are a nice size for preschooler art projects but, depending on your project, you might want to shrink these basic designs. You can't beat this price for getting some good basic stencils.

There are six precut zoo animal stencils in this sturdy little book. The pages are cardstock, reasonably durable for use with marking pens or paints. I like to use them to put menageries on my windows with tempera paints or dry-erase markers, but you'll come up with other things to use them for. The animals in this book include a giraffe, a polar bear, a lion, an elephant, a tiger, and a monkey. Great value!

The book helps people to learn the basics of electrical engineering. its not the most impressive book, but it will help college students understand the basics and the explanations of the book and problem are good.

This book covers a lot of areas in great detail, but nevertheless is surprisingly easy to read. Its coverage of some of the subjects like the different types of inverters is significantly more detailed compared to most introductory text books. It also discusses various circuit design techniques, not just the standard static CMOS design. However the book has one terrible section covering the body bias effect. The author shows a 2 terminal capacitor and says that if Vb is applied to the bulk instead of zero volts, then the Vth will change from Vto by the well known body effect. This is completely FALSE!!! Body effect is a 3 terminal device effect and doesn't exist for a 2 terminal capacitor. If you raise the voltage applied to the body by a certain amount, the Vgate has to change by the same amount in a 2 terminal capacitor. ( Not by the well known Sqrt (Vbs,..) relationship.) Not only that, but it can't be just Vb, it has to be Vbs--applied between substrate and the third terminal.AMAZING slip by a professor, and all who reviewed the book. (Tsividis' book will never have a sloppy discussion like this.) Overall this book covered many areas and was very useful. Of course it might be getting outdated in such a fast changing technology, but any desinger can benefit from this book.

In my opinion, as a GCSE art student, this book has been and still is an inspiration to me. It contains hundreds of beautiful photographs, so that even if, like me you are not a 'fungi fan' you can still admire the beauty of these creatures. This is a beautiful and informative book, and is well worth owning, even without any interest in the subject you can still be amazed by it.

Classical logic forces all actions to be described by a rigid sequence of two option rules. By applying enough such rules, it is possible to eventually reach a reasonable approximation to the problem in question. However, such a method is cumbersome at best, so in 1964, Lotfi Zadeh, a professor of electrical engineering, invented a new reasoning system base on imprecise rules. Since the values are now placed within specified ranges, the system was given the unfortunate name "fuzzy ." Eventually ignored and at times vilified by the academic community in the United States, fuzzy logic is now beginning to be widely used in commercial products.
In another instance of what seems to be the most common business theme of the decade of the '80s, it was Japanese industry that took the American ideas and made them commercially viable. Many products now incorporate fuzzy reasoning systems, with no end in sight regarding the spectrum of applications. The performance gains of fuzzy logic over other options is at times astounding.
Equally surprising is the simplicity of fuzzy reasoning. Most events in the human experience are not sharply demarcated. Night does not "fall," but slowly floats down like an aging helium balloon. Fuzzy systems mimic this by assigning a numeric value to qualifying words such as "very ," "slightly ," and "remotely ." The most common scale uses the range from zero to one inclusive. Since zero can be considered FALSE and one TRUE, classical logic is a limiting subset of fuzzy logic. For example, the phrase "very possible" could be assigned a truth value of 0.90, "slightly possible" a value of 0.05, and "remotely possible" a value of 0.005. Fuzzy OR then takes the largest value of the two variable, AND the minimum of the two and the negation is computed by taking one minus the fuzzy value.
This book introduces the basic notions of fuzziness, but concentrates more on the history as an ignored discipline and the recent commercial successes. It is amazing to learn that the vast majority of "fuzzy thinkers" are found in Asia. Comparisons between the differences in Western and Eastern philosophy are made in an attempt to explain this. For example, the Japanese language is inherently much more vague than western languages.
If you are interested in learning the first notions of fuzzy reasoning, this book is a good non-technical place to start. And if the applications continue to grow, that interest may become a required taste.

This book, is mostly about the Galileo's life. It is a biography of him. Galileo was born on January 8, 1610. He was a great astronomer, in fact, one of the greatest astronomers that had ever lived. He discovered many things that nobody else bothered to know about. He corrected many ancient theories, for example, Aristotle's. One of the theories of Aristotles was the theory of motion. Aristotle believed that heavier objects should fall faster than lighter objects. Galileo then was curious about this theory and tested it. It then seemed that Aristotle was incorrect. Galileo though had proof and told other people about the theory that he had. Many didn't believe him because Aristotle was one of the classics and had been around for centuries. Galileo did many other magnificent discoveries and corrections that had changed our lives. Today, we respect him as the greatest astronomer that had ever lived.
Why I recommend this book is that it is full of information. It tells about practically anything you want to know about Galileo. It is a useful reference book that is also surprisingly easy to understand. It shows and makes reading biographies fun.
Though I don't really have a favorite part, I enjoyed some of the sections in the book. Such as when Galileo finds that Aristotle's theories were mostly all incorrect, it was an amazing discovery and correction. The book also gave me knowledge about who named this and that.
