This book covers the theory necessary to understand wind energy basics, and proceeds as a how-to manual on shaping a simple turbine out of wood. It then shows how to build a low speed alternator out of a brake drum. (There is another book by Hugh called "Brake Drum Windmill Handbook" which goes into more detail).
The challenge is building an electrical generating system that operates at the slow rotational speeds of a wind turbine (e.g. 300 - 500 RPM). Everybody wants to hook up an automobile alternator, but even if it is optimized for high output at an idle, it probably will not start producing power until it reaches 1800 RPM. (Typically the engine/alternator pulleys have a ratio of 3 or 3.5 to 1 and the engine idles @ 600 RPM).
A great little book.

Mr. Price is absolutely right on the basics. Kids need to apply themselves in school. It teaches skills that are absolutely essential in life. How to acquire information, how to use it to form an opinion, and how to express that opinion. It also provides you with the foundation in mathematics and logic that is indispensable for thinking through problems both easy and hard.
His prescription is irrefutable. He calls for parents to be involved. Know what the school is teaching and how it assigns your child to a teacher. Know what the kids are doing after school. Know their friends. Know what they are watching on TV. Given that you can't keep them from listening to rap music, at least have an open discussion with them about the values being expressed.
He is right that black kids underperform kids of other races. They tend to become discouraged and adopt a defeatist attitude. More than that, kids who are not doing well spitefully drag down the kids who try, accusing them of "acting white." Everybody in education has wrestled with this set of problems, first to figure out what to do, and second to ascribe blame.
Here's where I take issue with Mr. Price. The blame invariably comes around to white folks. His book is full of charged words, among them racism, discrimination and low expectations. Many teachers of all races, based on their experience, come to have lower expectations of black kids. It is equally true that they are prudent to keep these opinions to themselves. But is this cause or effect?
Black authors, from Frederick Douglass through Larry Elder and Thomas Sowell, have made the same observations about African American students. Mr. Price points out that black kids tend to be channeled into special ed when the "act out" too much. He notes that after school programs are essential to keep kids from getting involved in crime and getting pregnant. He notes that there is a strong strain of anti-intellectualism in black popular culture. I cringe at the messages white kids pick up from black rappers and even from the Disney after-school programs with predominantly black casts. Was Bill Cosby the only black entertainer who offered a realistic and uplifting message? Do you ever hear of a similar problems with Vietnamese Americans?
Black students in the United States have higher levels of achievement than blacks anywhere else in the world. Brazil, with little acknowledged discrimination, is a disaster for blacks in terms of both education and income. Ditto the Caribbean, and the Caribbean coasts of Central American countries. The few native African scholars tend to work in the U.S. Some, like John Ogbu, embarrass the American black establishment with books like his " Black American Students in an Affluent Suburb: A Study of Academic Disengagement." Price could have provided footnotes when he disparaged "scientifically discredited" theories of intelligence. Can he reference authoritative rebuttals to the works of Murray and Herrenstein, Arthur Jensen and Philippe Rushton?
The school systems in the Washington D.C. area are mostly headed by black superintendents. Most have largely black boards and black faculties. There are many factors to discourage white teachers from working in these systems. A well-meaning teacher was chased out by angry parents in the "Nappy Hair" incident. The Washington Post chronicled the unfortunate experiences of some Ivy League liberal white teachers starting in the D.C. system. Teachers, black and white alike, are often intimidated and occasionally beaten up. Whatever the problems, it is hard any more to lay them at the feet of white administrators.
There is no disputing the widespread discrimination that existed under Jim Crow. On the other hand, there is no disputing that talented individuals like Clarence Thomas, Thomas Sowell, Condi Rice, Kenneth Chennault, Mr. Price himself and many, many others have overcome these difficulties to make sterling careers for themselves. I would call on Mr. Price to abandon blaming the white guy because it just isn't useful. Society has changed a lot, and more name-calling isn't likely to result in further beneficial change. It obscures areas where progress can be made.
Teachers are only human. Each of us have only finite intelligence and finite energy. We allocate our energies to those efforts that will yield the greatest reward. Mr. Price is naïve to say "children are entitled to the best education possible." No, children will get the education they and their parents demand.
Mr. Price overlooks the excellent option of private schools. Most target about 10% of their tuitions for financial aid. All are committed to the vague term "diversity." They actively seek and give preferential admission to black students. The schools recognize that it is a stretch for the kids. The portion of tuition they still must pay is significant. They often have to travel across town. Kids and parents are cliquish, sometimes excluding or patronizing black kids. But the kids who can put up with this atmosphere gain the benefit of small classes and bright and well-meaning teachers. The schools go out of their way to arrange tutors and whatever other support the kids need. The kids learn the essential life skill of moving comfortably in white society. And even if, as is often the case, they do not do as well in school as the other kids, they find that their social skills and athletic abilities always earn them a respected place in the school community. I hope that Mr. Price can recognize that while it is certainly true that "achievement matters," different peoples realize disproportionate achievements in different fields.
The common denominators of success are hard work, respect for community and family values, respect for the individual, a willingness to see each person as an individual. Mr. Price is dead on when he talks about the importance of character. People of character don't blame others. They take responsibility for their lives.

In simple to use language, Eco renews the inspiration and awe that was seen long ago in interpretation of the aesthetic. Thus, philosophy does not have to be something complicated, rather a basis for everything else we do. Therefore, when we see a painting, listen to a piece of music, read a poem, etc, we interpret the beauty that derives from that particular work and Eco, in this book shows us how we can do it by understanding the thought of one of the foremost thinkers of all time, St. Thomas Aquinas.
This book is a must have for philsophers, musicians, artists, and anyone who may be interested in interpreting art work, poetry, music, and the Beautiful with greater profundity.

It revises the mathematical notions required: controllability, observability, matrix calculation in a very precise & understandable manner.
Each concept is developed & deepened based on a general pattern involving presentation/procedures/examples, a summary of the chapter followed by references & applicative exercises.
It is divided into 5 main chapters:
- introduction: background material & matrix form description (MFD)
- system discretization: basic procedures such as step-invariant linearly interpolated models, etc
- system modeling: canonical forms, equivalent state space models for both single-input-single-output (SISO) and multi-input-multi-output (MIMO) systems.
- intermodel conversion: from state space models, transfer function models, Markov Parameters, etc
- system identification: identification identity, conversions from I/O samples and between discrete-time (DT) and continuous-time (CT).
3 Appendices complete the presentation:
A.Theory part of matrix algebra employed
B.Linear algebraic equations, Hessenberg transformations, Kalman decomposition,etc
C.Introduction to Linear Algebra and Systems (LAS,) a supporting design of linear control systems for implementation, and also the LAS code for specific algorithms.

This book is well organized and perfectly suited to the reader/traveller who is making a first aquaintance with the Alsace region of France. Though its main focus is introducing the many wines which are produced in this area, I found it to be very informative regarding the history, architecture, and other main attractions of the local cities, towns, and villages. I would definitely recommend it to the everyday traveller as well as the connoisseur interested in a wine touring holiday.
The preface of the book includes a general introduction to the area, its local cuisines, and wine making traditions. Accompanied with many great pictures, the book then reviews numerous towns and villages which are chosen primarily for their wine making appeal. Each town is introduced with a brief historical background and charmingly described in prose that belies the practical layout of the book: "Possibly the most beautiful spot in the Turckheim is the Place Turenne, tucked behind the Port de France gate. If you spend an evening in the village, listen out for the singing night watchman, who continues a centuries-old Turckheim tradition. Each evening at 10 pm, armed with his halberd and lantern, he walks through the streets passing through each of the gates and warns inhabitants to 'watch their hearths and candles'."
The book outlines the local hotels and restaurants in each town, including phone numbers and typical prices of these establishments. It also lists local places of interest, market times, and seasonal wine festivals.
My enthusiasm to visit Alsace has been greatly enhanced by this book. I can almost taste the choucroute and Munster cheese, imagining myself ensconsed in one of the many delightful Alsatian villages.
