Wireless communications, together with its applications and underlying technologies, is among today’s most active areas of technology development. The very rapid pace of im- provements in both custom and programmable integrated circuits for signal processing ap- plications has led to the justfiable view of advanced signal processing as a key enabler of the aggressively escalating capacity demands of emerging wireless systems. Consequently, there has been a tremendous and very widespread effort on the part of the research community to develop novel signal processing techniques that can fulfill this promise.

RFID networks are currently recognized as one a research area of priority. Research activities related to RFID technology have been booming recently. A number of ongoing projects are being funded in Europe, Asia, and North America. According to leading market analysts, the development of the RFID market is projected to increase from approximately $3 billion in 2005 to $25 billion in 2015. Several countries have dedicated innovation programs to support and develop RFID systems and related technologies: the RFID initiative in Taiwan, Ubiquitous Japan and the NSF SBIR program in the USA. The EU has recently advertised its Strategic Research Roadmap concerning the Internet of Things, which first of all refers to the RFID technology before being extended to commu- nicating devices as in M2M (Machine to Machine). In this roadmap, several application domains have been identified:

Current field forecast verification measures are inadequate, primarily because they compress the comparison between two complex spatial field processes into one number. Discrete wavelet transforms (DWTs) applied to analysis and contemporaneous forecast fields prove to be an insightful approach to verification problems. DWTs allow both filtering and compact physically interpretable partitioning of fields. These techniques are used to reduce or eliminate noise in the verification process and develop multivariate measures of field forecasting performance that are shown to improve upon existing verification procedures.

This edition of Digital Image Processing is a major revision of the book. As in the 1977 and 1987 editions by Gonzalez and Wintz, and the 1992, 2002, and 2008 editions by Gonzalez and Woods, this sixth-generation edition was prepared with students and instructors in mind. The principal objectives of the book continue to be to provide an introduction to basic concepts and methodologies applicable to digital image processing, and to develop a foundation that can be used as the basis for further study and research in this field. To achieve these objectives, we focused again on material that we believe is fundamental and whose scope of application is not limited to the solution of specialized problems. The mathematical complexity of the book remains at a level well within the grasp of college seniors and first-year graduate students who have introductory preparation in mathematical analysis, vectors, matrices, probability, statistics, linear systems, and computer programming. The book website provides tutorials to support readers needing a review of this background material

实验教学一直是工科教学中不可或缺的组成部分,对培养学生的动手能力,独立思考能力,创新思维与发散思维具有重要的作用。针对目前电路教学实验中电路仿真实验与实物电路实验各自独立,无法统一问题,提出将仿真电路实验与实物电路实验有机的结合同步操作,并使用Web发布实现远程实验操作。采用Multisim作为电路实验仿真平台,NI Eiviss II作为实物电路实验硬件平台,运用LabVIEW整合Multisim电路仿真实验与实物电路实验,实现仿真与实物实验有机结合,两种实验可同步进行。学生在仿真实验中先可探索实验,然后做实物实验。同时运用LabVIEW开发出实验过程人机交互操作接口界面,使用过程中效果良好。Experimental teaching has always been an indispensable part of engineering education.And it always plays an important role in cultivating students'practical ability,independent thinking ability,innovative thinking and divergent thinking.But simulation experiment and physical experiment cannot be unified in the circuit teaching experiment at present.In order to solve this problem,this paper proposes to combine organically the simulation circuit experiment with physical circuit experiment,and synchronously operate them.This paper uses the WEB publishing to achieve remote experimental operation.Multisim is used as the circuit simulation platform,and NI Eiviss II is used as the physical circuit hardware platform.Multisim circuit simulation experiment and physical circuit experiment are implemented by LabVIEW to realize the combination of simulation experiment and physical experiment.Students do explore experiments in simulation experiment firstly,and then do physical experiment.And this paper uses LabVIEW to develop the experimental man-machine interface.

经过几天的摸索我终于掌握用STM8库的方法，但我还认为不用库也很好，1.首先要装好ST8的开发环境，一个是ST Visual develop一个是COSMIC stm8C语言编译器.第三把STM8的库下下来2.建立一个新的环境和一个工程，当然工程和环境可同名3.这一点是关键，把STM8库下的*FWLib/project\STVDCosmic STM8_interrupt_vetor.c考到你的新工程目录下4.打开库中的example目录下的一个例子，把除了STM8_interrupt_vetor.c的所有东东考到你的工程下边5，然后把要涉及的文件包进去，这里注意当编译时提示，没有函数时，大家把函数名考一下，到库CHM文件索引下，然后把C文件包含到include6.这时编译大功告成了
