Today s ActionScript-based applications require increasingly sophisticated architectures and code. This book aids intermediate and advanced ActionScript developers in learning how to plan and build applications more effectively. You ll learn how to apply design patterns as solutions to common programming scenarios. Beyond a reference, Advanced ActionScript with Design Patterns is a practical guide complete with sample mini-applications illustrating each design pattern. The accompanying CD includes a trial version of Flash 8 along

匀速升温控制是个复杂的过程,具有大惯性、纯滞后、非线性等特点,难以得到精确的数学模型。考虑到这些特点,为提高控制精度,将Fuzzy-PID算法应用于电阻炉温度控制系统,当误差较大时采用模糊控制,误差较小时采用模糊PID控制,实现了2种控制方法的优势互补,在此基础上,给出了Fuzzy-PID控制器设计、硬件结构和软件设计,实验曲线表明该控制算法可以获得满意的控制效果,采用模糊PID控制的效果明显优于常规PID控制。

This a simple database management system. It doesn t use any other code (i.e. ODBC, ADO, etc.) and has it s own database file format. I wrote it because I found the other DBMSs code too bulky and hard to debug. It s designed for small applications and I doubt it could handle anything on a large scale. A sample program included in the .zip shows how everything works. The database project is a library project, so you ll have to compile and link with the .lib file to get everything working. Pros: - You have the source code so you know exactly what it is doing - Database files are very small - Small and fast code Cons: - Can t handle large amounts of records (more than 65000ish) - Doesn t support SQL (you have to search the database by cycling through the records and testing them against your constraints) - Each database file can only have one table.

This Handbook, published under the auspices of the Senior NATO Logisticians’ Conference (SNLC), i s i ntended as a simple guide to logistics i n NATO. It does not attempt to examine current i ssues or provide answers to the problems that logisticians will face, but i t rather aims at i ntroducing them to some of the basic principles, policies, concepts and organisations with which they will work.
