Abstract: What can be SIMPLER than designing with CMOS and BiCMOS? These technologies are very easy to use butthey still require careful design. This tutorial discusses the odd case of circuits that seem to work but exhibit somepeculiar behaviors—including burning the designer's fingers!

如今的開關穩壓器和電源越來越緊湊,性能也日益強大,而越來越高的開關頻率是設計人員面臨的主要問題之一,正是它使得PCB的設計越來越困難。事實上,PCB版圖已經成為區分好與差的開關電源設計的分水嶺。本文針對如何一次性創建優秀PCB版圖提出一些建議。考慮一個將24V降為3.3V的3A開關穩壓器。設計這樣一個10W穩壓器初看起來不會太困難,設計人員可能很快就可以進入實現階段。不過,讓我們看看在采用Webench等設計軟件后,實際會遇到哪些問題。如果我們輸入上述要求,Webench會從若干IC中選出“SIMPLER Switcher”系列中的LM25576(一款包括3A FET的42V輸入器件)。該芯片采用帶散熱墊的TSSOP-20封裝。Webench菜單中包括了對體積或效率的設計優化。設計需要大容量的電感和電容,從而需要占用較大的PCB空間。Webench提供如表1的選擇。

The module LSQ is for unconstrained linear least-squares fitting. It is based upon Applied Statistics algorithm AS 274 (see comments at the start of the module). A planar-rotation algorithm is used to update the QR- factorization. This makes it suitable for updating regressions as more data become available. The module contains a test for singularities which is SIMPLER and quicker than calculating the singular-value decomposition. An important feature of the algorithm is that it does not square the condition number. The matrix X X is not formed. Hence it is suitable for ill- conditioned problems, such as fitting polynomials. By taking advantage of the MODULE facility, it has been possible to remove many of the arguments to routines. Apart from the new function VARPRD, and a back-substitution routine BKSUB2 which it calls, the routines behave as in AS 274.

驅動開發向導 I came across an article QuickSYS which implements an NT driver framework. That article demonstrates a MFC application that gets a project name as a parameter and creates Visual C++ workspace with NT driver framework. I decided to copy the NT driver framework source and to put it in the Visual Studio project wizard as seen above. This is SIMPLER rather than running an external executable application that generates the code for you.

This project developed in java leads us to realize a flight reservation system in order to emulate databases containing the structures for the flight and for the booking. These bases extend the List interface and implements additional search鈥檚 methods. Two interfaces provide an access to this system. The first one reads and handles reservation request message from a terminal. The arguments are then processed throw a middleware interface that call the flight system methods. The second one, a Graphical User Interfaces (GUI) application using Swing Java Foundation Classes (JFC), offers a SIMPLER access to the systems.

The Pages 2.0 specification is one of the most exciting Java Community Process releases of the year. Chances are you picked this book to learn more about the new features of 2.0. Or you may be interested in using for the first time in your next project. Regardless of your interest, we ve put together a book that tries to bring you up to speed fast. The goal of has been to make it easier to create sophisticated, well-designed Web applications. We feel that the authors of the specification have achieved their goal. Working with databases or XML has never been SIMPLER. Your applications can be functionally well-organized. You can create your own reusable components.

ADIAL Basis Function (RBF) networks were introduced into the neural network literature by Broomhead and Lowe [1], which are motivated by observation on the local response in biologic neurons. Due to their better approximation capabilities, SIMPLER network structures and faster learning algorithms, RBF networks have been widely applied in many science and engineering fields. RBF network is three layers feedback network, where each hidden unit implements a radial activation function and each output unit implements a weighted sum of hidden units’ outputs.
