This history of woodworking hand tools from the 17th to the 20th century is one of a very gradual evolution of tools through generations of craftsmen. As a result, the sources of changes in design are almost impossible to ascertain. Published sources, moreover, have been concerned primarily with the object shaped by the tool rather than the tool itself. The resulting scarcity of information is somewhat compensated for by collections in museums and restorations.
Electrical Engineering Dictionary is a continually updated CD that provides workable definitions for practicing engineers. It serves as a reference and research tool for students and offers practical information for scientists and researchers in other disciplines. Areas examined include applied electrical engineering, microwave engineering, control engineering, power engineering, digital systems engineering, and device electronics.
Chúng ta đã biết CAD xuất hiện vào trước năm 1960, với tư cách là công cụ vẽ (Drafting Tool). Vì vậy, trước đây nó được gọi là "cây bút chì điện tử" (Electronic Pencil). Cho đến những năm 80 của thế kỷ trước, vẽ vẫn là chức năng cơ bản của các phần mềm CAD.

Unfortunately, much of what has been written about software engineering comes from an academic perspective which does not always address the everyday concerns that software developers and managers face. With decreasing software budgets and increasing demands from users and senior management, technology directors need a complete guide to the subject of software engineering. The successor to the bestselling Software Engineering Productivity Handbook, this book fulfills that need.
Achieving state-of-the-art excellence and attaining the cost reductions associated with outstanding logistics efforts is an obvious gain in terms of competitive edge and profitability. As logistics tools evolve in comprehensiveness and complexity, and the use of these new tools becomes more pervasive, maintaining a position of leadership in logistics functions also becomes increasingly difficult. And in spite of its importance not only to the bottom line but also to the functionality of your operations, logistics improvement often lags industry requirements....
This is a reference book for those practicing or otherwise having an interest in design
for manufacturability (DFM). DFM principles and guidelines are many; no one person
should be expected to remember them all nor the detailed information, such as suggested
dimensional tolerances, process limits, expected surface finish values, or other
details, of each manufacturing process. It is expected that those involved will keep this
book handy for reference when needed.
Clearly and elegantly presented, Mathematical Methods in Science and Engineering provides a coherent treatment of mathematical methods, bringing advanced mathematical tools to a multidisciplinary audience. The growing interest in interdisciplinary studies has brought scientists from many disciplines such as physics, mathematics, chemistry, biology, economics, and finance together, which has increased the demand for courses in upper-level mathematical techniques.
Engineers use the concepts and methods of mechanics of solids in designing and evaluating tools, machines, and structures, ranging from wrenches to cars to spacecraft. The required educational back ground for these includes courses in statics, dynamics, mechanics of materials, and related subjects.
This is the first book in a three-volume series deploying MATLAB-based applications in almost every branch of science.

The book consists of 20 excellent, insightful articles and the readers will find the results very useful to their work. This collection of high quality articles, refers to a large range of professional fields and may be used for scientific, engineering and educational purposes....
• Means you may risk possible bodily harm Important: • Means you risk damage to the vehicle or the tool Notes: are added to provide clarity and helpful tips These safety messages cover situations SPX is aware of. SPX cannot know, evaluate and advise you as to all of the possible hazards. You must be certain that any conditions or service procedures encountered do not jeopardize your personal safety.
Social engineering là phương pháp phi kỹ thuật đột nhập vào hệ thống hoặc mạng công ty. Đó là quá trình đánh lừa người dùng của hệ thống, hoặc thuyết phục họ cung cấp thông tin có thể giúp chúng ta đánh bại bộ phận an ninh. Social engineering là rất quan trọng để tìm hiểu, bởi vì hacker có thể lợi dụng tấn công vào yếu tố con người và phá vỡ hệ thống kỹ thuật an ninh hiện tại.
The concept of this book is that of a personal tool, which compacts 20 percent of the data is needed 80 percent of the time by electrical design professionals in the preliminary design of buildings of all types and sizes. This tool is meant to always be at one's fingertips ( open on a drawing board, desk, or computer table; carried in a briefcase; or kept in one's pocket).

With this book, you can build exciting, scalable web applications quickly and confidently, using Google App Engine — even if you have little or no experience in programming or web development. App Engine is one of the most exciting web technologies to appear in the last year, providing a simple, easy-to-use application framework with basic web tools. While Google’s own tutorial assumes significant development experience, Using Google App Engine is for anyone who wants to get started with this platform....
"Introduction to Matlab for Engineers" is a simple, concise book designed to be useful for beginners and to be kept as a reference. Matlab is a globally available standard computational tool for engineers and scientists. The terminology, syntax, and the use of the programming language are well defined, and the organization of the material makes it easy to locate information and navigate through the textbook. The text covers all the major capabilities of MATLAB that are useful for beginning students.
Animation and Sound in Matlab
The primary focus of this book is the rapidly evolving software technology for
supporting the development, execution, management, and experimentation
with parallel and distributed computing environments.
