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

勻速升溫控制是個(gè)復(fù)雜的過程,具有大慣性、純滯后、非線性等特點(diǎn),難以得到精確的數(shù)學(xué)模型。考慮到這些特點(diǎn),為提高控制精度,將Fuzzy-PID算法應(yīng)用于電阻爐溫度控制系統(tǒng),當(dāng)誤差較大時(shí)采用模糊控制,誤差較小時(shí)采用模糊PID控制,實(shí)現(xiàn)了2種控制方法的優(yōu)勢(shì)互補(bǔ),在此基礎(chǔ)上,給出了Fuzzy-PID控制器設(shè)計(jì)、硬件結(jié)構(gòu)和軟件設(shè)計(jì),實(shí)驗(yàn)曲線表明該控制算法可以獲得滿意的控制效果,采用模糊PID控制的效果明顯優(yōu)于常規(guī)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.
