A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running computation, block while waiting for an event, or read files from the file system. Unlike kernel drivers, a user-space device driver can use other device drivers--that is, access the network, talk to a serial port, get interactive INPUT from the user, pop up GUI windows, or read from disks. User-space drivers implemented using FUSD can be much easier to debug it is impossible for them to crash the machine, are easily traceable using tools such as gdb, and can be killed and restarted without rebooting even if they become corrupted. FUSD drivers don t have to be in C--Perl, Python, or any other language that knows how to read from and write to a file descriptor can work with FUSD. User-space drivers can be swapped out, whereas kernel drivers lock physical memory.

This functions computes SARMA or multiplicative (p,q) x (P,Q) models for (p,q,P,Q) in (pvec x qvec x Pvec x Qvec) it returns the best according to AIC where AIC has been modified to account for fixed parameters x = INPUT data pvec = vector of p s set pvec=[0] for no AR qvec = vector of q s set qvec=0[] for no MA Pvec = vector of P s Qvec = vector of Q s T period for multiplicative model

一個不帶界面的計算器,用戶只需要在文本文件INPUT.txt中輸入計算表達式,即可通過運行程序得到結果,輸出在output.txt中; 支持加減乘除,取余數,乘方,括號等等; 如:5+4 = 輸出9 5+4*4+9/3 = 輸出24 (5+4)*4+9/3 = 輸出39 (50+4)*(40 3)+288/(147-3) = 輸出56 (50+4)^2*(40 3)+288/(147-3) = 輸出2918

Help Desk Pro has three different interfaces for all three domains of users, providing them with the controls required by them, to save time the application generates reports, which are dynamic as well, taking INPUT from admin and generating results.As for the user account management, the user him/herself can edit their account and personal set-up and the admin can make representatives and admin.

Short description: GUI Ant-Miner is a tool for extracting classification rules from data. It is an updated version of a data mining algorithm called Ant-Miner (Ant Colony-based Data Miner), which was proposed in 2002 by Parpinelli, Lopes and Freitas. GUI Ant-Miner differs from the original algorithm as follows: It has a friendly graphical user interface, makes possible the use of ant populations within the Ant Colony Optimization (ACO) concept, data INPUT file is standardized with the well-known Weka system, and runs on virtually any operating system since it is written in Java.

SWFUpload是一個客戶端文件上傳工具,最初由Vinterwebb.se開發,它通過整合Flash與JavaScript技術為WEB開發者提供了一個具有豐富功能繼而超越傳統<INPUT type="file" />標簽的文件上傳模式。 SWFUpload的主要特點 * 可以同時上傳多個文件; * 類似AJAX的無刷新上傳; * 可以顯示上傳進度; * 良好的瀏覽器兼容性; * 兼容其他JavaScript庫 (例如:jQuery, Prototype等); * 支持Flash 8和Flash 9; SWFUpload不同于其他基于Flash構建的上傳工具,它有著優雅的代碼設計,開發者可以利用XHTML、CSS和JavaScript來隨心所欲的定制它在瀏覽器下的外觀;它還提供了一組簡明的JavaScript事件,借助它們開發者可以方便的在文件上傳過程中更新頁面內容來營造各種動態效果。 在使用SWFUpload之前,請確認你具備一定的JavaScript和DOM知識。在實際開發中,大部分的錯誤都是由于錯誤的設置和低劣的Event Handlers處理程序所造成的。

This application note considers the design of frequency- selective filters, which modify the frequency content and phase of INPUT signals according to some specification. Two classes of frequency-selective digital filters are considered: infinite impulse response (IIR) and finite impulse response (FIR) filters. The design process consists of determining the coefficients of the IIR or FIR filters, which results in the desired magnitude and phase response being closely approximated.
