Text processing often involves matching text against a pattern. Although Java s character and assorted string classes offerlow- levelpattern- matching support, that support commonly leads to complex code. To help you write simplerpattern- matching code, Java provides regular expressions. After introducing you to terminology and thejava.util. regex package, Jeff Friesen explores many regular expression constructs supported by that package s Pattern class. Then he examines Pattern s methods and the additionaljava.util. regex classes. In conclusion, he presents a practical application of regular expressions.

The ability to write efficient, high-speed arithmetic routines ultimately depends upon your knowledge of the elements of arithmetic as they exist on a computer. That conclusion and this book are the result of a long and frustrating search for information on writing arithmetic routines for real-time embedded systems. With instruction cycle times coming down and clock rates going up, it would seem that speed is not a problem in writing fast routines. In addition, math coprocessors are becoming more popular and less expensive than ever before and are readily available. These factors make arithmetic easier and faster to use and implement. However, for many of you the systems that you are working on do not include the latest chips or the faster processors. Some of the most widely used microcontrollers used today are not Digital Signal Processors (DSP), but simple eight-bit controllers such as the Intel 8051 or 8048 microprocessors.

Throughout the course of my work in multihop mobile ad hoc networks (MANET) over the last several years, I reached the conclusion that mobility models and perfor- mance metrics need to be treated in detail in designing these networks that are the ultimatefrontierinwirelesscommunications. Awidevarietyofmobilitymodelscan be used by mobile nodes.

目的:自主研制一款超声手术刀电源控制系统,以减少能量的消耗,维持手术刀的正常温度。方法:对超声换能器在谐振附近的等效电路建立模型,并设计基于数字信号处理(DSP)的超声手术刀的硬件控制系统。结果:经对电源控制系统的电路和工作性能测试,生成的电流和电压的有效值等参数,能够及时调整电源的频率,并达到预期的功能指标,使超声手术刀工作在谐振状态。结论:以DSP为核心设计的超声手术刀电源控制系统,测试指标均能够达到预期的要求,能够使系统在谐振状态下工作。Objective: To independently develop a power control system of ultrasonic scalpel so as to reduce the energy consumption and maintain the normal temperature of ultrasonic scalpel. Methods: In this paper, the model of equivalent circuit of ultrasonic transducer nearby syntony was built up, and the hardware control system of ultrasonic scalpel based on digital signal processing(DSP) was designed. Results: Through testing the circuit and work performance of power control system, the series of parameters such as effective value and so on which were produced by this system could adjust frequency of power source in time and attain anticipative functional indicator, and it took the ultrasonic scalpel to work in syntonic situation. conclusion: The tested indicators of power control system of ultrasonic scalpel based on the kernel design of DSP can attain anticipative requirement, and can take this system to work in syntonic situation.
