The PMSM FOC is made of several C modules, compatible with the free-of-charge IAR EWARM KickStart edition toolchain version 4.42. It is used to quickly evaluate both the MCU and the available tools. In addition, when used together with the STM32F103xx motor control starter kit (STM3210B-MCKIT) and PM motor, a motor can be made to run in a very short time. It also eliminates the need for time-consuming development of FOC and speed regulation algorithms by providing ready-to-use functions that let the user concentrate on the application layer. Moreover, it is possible to get rid of any speed sensor thanks to the sensorless algorithm for rotor position reconstruction.

This file contains a C++Builder 4 project called SimplyChaos-X ver 3.1 (SCX31). SCX31 is an encryption tool. I designed it as my graduation paper work. SCX31 is a symmetric stream cipher built on chaos function, one time pad cipher and inspiration from Ground Effect (aviation). The key length can be up to 40 characters (320 bits).

JLAB is a set of Matlab functions I have written or co-written over the past fifteen years for the purpose of analyzing data. It consists of four hundred m-files spanning thirty thousand lines of code. JLAB includes functions ranging in complexity from one-line aliases to high-level algorithms for certain specialized tasks. These have been collected together and made publicly available for you to use, modify, and --- subject to certain very reasonable constraints --- to redistribute. Some of the highlights are: a suite of functions for the rapid manipulation of multi-component, potentially multi-dimensional datasets a systematic way of dealing with datasets having components of non-uniform length tools for fine-tuning figures using compact, straightforward statements and specialized functions for spectral and time / frequency analysis, including advanced wavelet algorithms developed by myself and collaborators.

小程序應有如下功能： 1、登記。登記每位同學的上網卡號，押金(>=5 RMB)和上網時刻。 2、查詢。可以查詢每個上網卡號的上網時刻，上網的時間，押金和當前的費用。 3、結賬。根據卡號可以算出 應收金額，應找金額。 4、提醒。當某個上網卡號的 上網費用 >= 它的押金時應提醒管理員。 5、續費。當某個上網卡號的 上網費用 >= 它的押金，他可以再次交上一定金額的押金(>=5 RMB)。 6、修改費率。上網的費率應可以調整。默認的費率是1 RMB /1小時。 為了不讓機房賠本，應是這樣的收費模式：先付錢后上網。如上機就五角， 以后過半小時收五角。 7、總賬。一天下來管理員要知道這天他賺了多少RMB。 你需要考慮程序被意外結束等特殊情況。 如果你的程序是按系統時間進行計時，還應考慮系統時間被意外更改的特殊情況。總之，你應考慮一切會讓你的程序不能正常運行的特殊情況。 如果不知道怎么計時，你可以學習參考使用<time.h>中函數。 說明： a. 假定機房有150臺機器。 b. 假定初始的費率是1 RMB /1分鐘(便于測試)。

Coaxial feed structures are widely used in ultra-wide band antennas . This paper modeled the characteristic of the monopole antenna feeded by coaxial line by FDTD in the time-domiain,which showes that . Firstly, it introduced the theory of the arithmetic and the particularly realization in the calculation then it described the use in the time-domain finally it analysed several characteristics of the monopole antenna. The arithmetic used in the microstrip antenna is also a quick and economical way to design the antenna.

This handbook is a concise guide to architecting, designing, and building J2EE applications. It guides technical architects through the entire J2EE project, including identifying business requirements, performing use-case analysis, doing object and data modeling, and leading a development team through construction. Whether you are about to architect your first J2EE application or are looking for ways to keep your projects on-time and on-budget, you will refer to this handbook again and again.
