  • Môi trường lắp ráp Trong Pro/ENGINEER chế độ lắp ráp (Assembly) được sử dụng để lắp ráp các chi tiết lại với nhau thành cụm lắp hoặc một máy hoàn chỉnh. Các bộ phận lắp ráp (Component) có thể là các chi tiết (Part) hoặc các cụm lắp (SubAssembly) có sẵn hoặc có thể được tạo mới trực tiếp từ trong môi trường lắp ráp. Quá trình chèn các chi tiết có sẵn để hình thành một lắp ráp được gọi là lắp ráp từ dưới lên trên.

  • The processes of manufacture and assembly are based on the communication of engineering information via drawing. These drawings follow rules laid down in national and international standards. The organisation responsible for the international rules is the International Standards Organisation (ISO). There are hundreds of ISO standards on engineering drawing because drawing is very complicated and accurate transfer of information must be guaranteed. The information contained in an engineering drawing is a legal specification, which contractor and sub-contractor agree to in a binding contract.

  • Beginning with a basic primer on reverse engineering-including computer internals, operating systems, and assembly language-and then discussing the various applications of reverse engineering, this book provides readers with practical, in-depth techniques for software reverse engineering. The book is broken into two parts, the first deals with security-related reverse engineering and the second explores the more practical aspects of reverse engineering.

  • The introduction of robots into modern industry is strongly connected with production automation where robots are used for material and parts manipulation and direct manipulation of tools in a technological process. Implementation of robots decreases production costs, increases productivity, assures the quality of production, and can replace employees at hard and dangerous operations.

  • For many manufacturing enterprises, assembly is an important portion of the final costs. Effectiveness was traditionally hunted for by reducing complex schedules into unit tasks (scientific work organization) and by enabling sequential assembly lines (vertical flow-shop). The approach leads to the highest productivity, and it is prised for mass production. Flow-lines and fixed schedules, however, require amortisation plans based on steady programmes on duty horizons corresponding to product volumes exceeding some minimal threshold.

  • We found that students entering our senior design course who had the expectation of something “real” being built were unprepared for doing prototyping activities or for incorporating a microcontroller component into their designs. We did offer a course in microcontrollers, but it was an elective senior-level course and many students had not taken that course previous to senior design. In spring 2002, the Computer Engineering Steering committee reexamined our goals for the first course in microprocessors and the approach for this book was developed.

  • At the request of the National Science Foundation Engineering Directorate, the National Academies performed an international benchmarking exercise to determine the standing of the U.S. research enterprise in the field of mechanical engineering relative to its international peers. This of course was no trivial undertaking, even for the panel of mechanical engineers assembled—11 members, mostly from U.S.

  • When this document was first produced back in 2001 data recovery was (and still is for many people) a very expensive option. While the Freeze it, beat it, and drop it option is still used by some, the current size and sensitivity newer larger hard drives makes these options extremely dangerous and definitely not recommended for hard drives with a capacity greater than more than 1 GB. And even then showed some activity here should be approached with carefully. Get it wrong by trying to save some money going to cost you more if then you decide to pass on your hard drive to a...
