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.

The use of renewable energy systems, such as wind power, hydropower, tidal
power, solar power, geothermal power and biomass burn is growing. Research in
electric power generation from renewable sources is continuously expanding and
stands for an area of high technological and financial importance. The implemen-
tation of new technologies for the functioning and management of renewable
energy systems will help to further Develop the renewable energy sector.

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

實驗教學一直是工科教學中不可或缺的組成部分,對培養學生的動手能力,獨立思考能力,創新思維與發散思維具有重要的作用。針對目前電路教學實驗中電路仿真實驗與實物電路實驗各自獨立,無法統一問題,提出將仿真電路實驗與實物電路實驗有機的結合同步操作,并使用Web發布實現遠程實驗操作。采用Multisim作為電路實驗仿真平臺,NI Eiviss II作為實物電路實驗硬件平臺,運用LabVIEW整合Multisim電路仿真實驗與實物電路實驗,實現仿真與實物實驗有機結合,兩種實驗可同步進行。學生在仿真實驗中先可探索實驗,然后做實物實驗。同時運用LabVIEW開發出實驗過程人機交互操作接口界面,使用過程中效果良好。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.

經過幾天的摸索我終于掌握用STM8庫的方法，但我還認為不用庫也很好，1.首先要裝好ST8的開發環境，一個是ST Visual Develop一個是COSMIC stm8C語言編譯器.第三把STM8的庫下下來2.建立一個新的環境和一個工程，當然工程和環境可同名3.這一點是關鍵，把STM8庫下的*FWLib/project\STVDCosmic STM8_interrupt_vetor.c考到你的新工程目錄下4.打開庫中的example目錄下的一個例子，把除了STM8_interrupt_vetor.c的所有東東考到你的工程下邊5，然后把要涉及的文件包進去，這里注意當編譯時提示，沒有函數時，大家把函數名考一下，到庫CHM文件索引下，然后把C文件包含到include6.這時編譯大功告成了
