One of the most important issues affecting the implementation of microcontroller software deals with the data-decision algorithm. Data-decision refers to decoding the DIO-pin from the CC400/CC900. Two main principles exist for decoding Manchester-coded data: Data decision based on timing the period between transitions, and data decision based on oversampling.

計算所漢語詞法分析系統ICTCLAS介紹 詞是最小的能夠獨立活動的有意義的語言成分。 但漢語是以字為基本的書寫單位，詞語之間沒有明顯的區分標記，因此，中文詞語分析是中文信息處理的基礎與關鍵。為此,我們中國科學院計算技術研究所在多年研究基礎上，耗時一年研制出了漢語詞法分析系統ICTCLAS(Institute of Computing Technology, Chinese Lexical Analysis System)，該系統的功能有：中文分詞；詞性標注；未登錄詞識別。分詞正確率高達97%以上，未登錄詞識別召回率均高于90%，其中中國人名的識別召回率接近98%處理速度為31.5Kbytes/s。ICTCLAS的特色還在于：可以根據需要輸出多個高概率結果，有多種輸出格式，支持北大詞性標注集，973專家組給出的詞性標注集合。該系統得到了專家的好評，并有多篇論文在國內外發表。 計算所漢語詞法分析系統ICTCLAS同時還提供一套完整的動態連接庫ICTCLAS.dll和相應的概率詞典,開發者可以完全忽略漢語詞法分析，直接在自己的系統中調用ICTCLAS，ICTCLAS可以根據需要輸出多個高概率的結果，輸出格式也可以定制，開發者在分詞和詞性標注的基礎上繼續上層開發。

This book is about the management of business processes. This is certainly not a new topic. Since the beginning of the Industrial Revolution, it has been written about from every possible point of view—economic, sociological, psychological, accountancy, mechanical engineering and business administration. In this book, we examine the management of business processes from the perspective of computing, or—to put it more broadly—of information technology. The reason is that information technology has made huge leaps forward in recent years, resulting in the creation of completely new ways of organizing business processes. The development of generic software packages for managing business processes—so-called workflow management systems (WFMS)—is particularly important in this respect.

This book is intended for "hands-on" developers or advanced students interested in understanding the strategies and tactics of concurrent network programming using C++ and object-oriented design. We describe the key design dimensions, patterns, and principles needed to develop flexible and efficient concurrent networked applications quickly and easily. Our numerous C++ code examples reinforce the design concepts and illustrate concretely how to use the core classes in ACE right away. We also take you "behind the scenes" to understand how and why the IPC and concurrency mechanisms in the ACE toolkit are designed the way they are. This material will help to enhance your design skills and to apply C++ and patterns more effectively in your own object-oriented networked applications.

PCI Hot-Plug Specification Revision 1.0 The primary objective of this specification is to enable higher availability of file and application servers by standardizing key aspects of the process of removing and installing PCI adapter cards while the system is running. Although these same principles can be applied to desktop and portable systems using PCI buses, the operations described here target server platforms.

I believe that technology has the capacity to fundamentally improve people’s lives, and improve the world in which we live.We are now two years into what my company have called the ‘Digital Decade’.We think that by 2010 a combination of hardware and software innovation with broader social trends will change the way computing fits into our society. Mobile technology is a central part of this vision.

Java Regex Primer Since version 1.4, Java has had support for Regular Expressions in the core API. Java Regex follows the same basic principles used in other languages, just withdi erent access methods, and some subtledi erences with the patterns. This primer is aimed towards developers already familiar with regex in other languages wanting a brief outline of its support in Java. It may also be beneficial to developers learning regex if used in conjunction with detailed documentation explaining the construction of regex patterns. Reading the javadoc forjava.util.regex. Pattern is a must to see how the Java regex patterns aredi erent from other languages such as Perl. Most of the functions discussed herin are from thejava.util.regex. Matcher class with a few fromjava.util.regex. Pattern. Reading this text in conjunction with the javadoc of those classes is advised.

In 1960, R.E. Kalman published his famous paper describing a recursive solution to the discrete-data linear filtering problem. Since that time, due in large part to advances in digital computing, the Kalman filter has been the subject of extensive research and application, particularly in the area of autonomous or assisted navigation.

In 1960, R.E. Kalman published his famous paper describing a recursive solution to the discretedata linear filtering problem [Kalman60]. Since that time, due in large part to advances in digital computing, the Kalman filter has been the subject of extensive research and application, particularly in the area of autonomous or assisted navigation. A very “friendly” introduction to the general idea of the Kalman filter can be found in Chapter 1 of [Maybeck79], while a more complete introductory discussion can be found in [Sorenson70], which also contains some interesting historical narrative.
