As I write this foreword, I am collaborating with four leading user interface (UI) component vendors on a presentation for the 2004 JavaOneSM conference. In our presentation, the vendors will show how they leverage JavaServerTM Faces technology in their products. While developing the presentation, I am learning some things about the work we’ve been doing on JavaServer Faces for the past three years. The vendors have their own set of concerns unique to adapting their product for JavaServer Faces, but they all voice one opinion loud and clear: they are very relieved to finally have a standard for web-based user interfaces.

After decades of war one company, who had gained powerful supplying both sides with weaponary, steps forwards and crushes both warring factions in one swift movement. Using far superior weaponary and AI craft, the company was completely unstoppable and now no one can stand in their way. Thousands began to perish under the iron fist of the company. The people cried out for a saviour, for someone to light this dark hour... and someone did.

This is a simple operating system source code in assembly langauge, you should compile the files in the rar with MASM, and put them in one image (kernel follows loader) and test it with vmware.

Use the fast Fourier transform function fft to analyse following signal. Plot the original signal, and the magnitude of its spectrum linearly and logarithmically. Apply Hamming window to reduce the leakage. . The hamming window can be coded in Matlab as for n=1:N hamming(n)=0.54+0.46*cos((2*n-N+1)*pi/N); end; where N is the data length in the FFT.

We introduce a sub-cell WENO reconstruction method to evaluate spatial derivatives in the high-order ADER scheme. The basic idea in our reconstruction is to use only r stencils to reconstruct the point-wise values of solutions and spatial derivatives for the 2r-1 th order ADER scheme in one dimension, while in two dimensions, the dimension-by-dimension sub-cell reconstruction approach for spatial derivatives is employed. Compared with the original ADER scheme of Toro and Titarev (2002) [2] that uses the direct derivatives of reconstructed polynomials for solutions to evaluate spatial derivatives, our method not only reduces greatly the computational costs of the ADER scheme on a given mesh, but also avoids possible numerical oscillations near discontinuities, as demonstrated by a number of one- and two-dimensional numerical tests. All these tests show that the 5th-order ADER scheme based on our sub-cell reconstruction method achieves the desired accuracy, and is essentially non-oscillatory and computationally cheaper for problems with discontinuities.

Wireless technologies like GSM, UMTS, LTE, Wireless LAN and Bluetooth have revolutionized the way we communicate by making services like telephony and Internet access available anytime and from almost anywhere. Today, a great variety of technical publications offer background information about these technologies but they all fall short in one way or another. Books covering these technologies usually describe only one of the systems in detail and are generally too complex as a first introduction. The Internet is also a good source, but the articles one finds are usually too short and super- ficial or only deal with a specific mechanism of one of the systems. For this reason, it was difficult for me to recommend a single publication to students in my telecommunication classes, which I have been teaching in addition to my work in the wireless telecommunication industry. This book aims to change this.

開關在電路中起接通信號或斷開信號的作用。最常見的可控開關是繼電器，當給驅動繼電器的驅動電路加高電平或低電平時，繼電器就吸合或釋放，其觸點接通或斷開電路。CMOS模擬開關是一種可控開關，它不象繼電器那樣可以用在大電流、高電壓場合，只適于處理幅度不超過其工作電壓、電流較小的模擬或數字信號。 一、常用CMOS模擬開關引腳功能和工作原理 1.四雙向模擬開關CD4066 CD4066 的引腳功能如圖1所示。每個封裝內部有4個獨立的模擬開關，每個模擬開關有輸入、輸出、控制三個端子，其中輸入端和輸出端可互換。當控制端加高電平時，開關導通；當控制端加低電平時開關截止。模擬開關導通時，導通電阻為幾十歐姆；模擬開關截止時，呈現很高的阻抗，可以看成為開路。模擬開關可傳輸數字信號和模擬信號，可傳輸的模擬信號的上限頻率為40MHz。各開關間的串擾很小，典型值為－50dB。
