Unix is distinguished by a simple, coherent, and elegant design — truly remarkable features that have enabled the system to influence the world for more than a quarter of a century. And especially thanks to the growing presence of Linux, the idea is still picking up momentum, with no end of the growth in sight.

TortoiseSVN 是一个 Windows 下的版本控制系统 Apache™ Subversion® 的客户端工具。就是 说，TortoiseSVN 常年管理文件和目录。文件存储于一个中央版本库中。版本库就像一个常见的文件服 务器，除了它保存你对文件和目录所有的改变。这一特性使得你可以恢复文件的旧版本并查看历史-谁 在什么时间如何进行的修改。这就是为什么很多人认为 Subversion 和版本控制系统是一种“时间机 器”。

This paper presents an algorithm for automatically locating the waveform boundaries
the onsets and ends of P QRS and T waves in multilead ECG signals
the  standard leads and the orthogonal XYZ leads Given these locations features of clinical importance
such as the RR interval the PQ interval the QRS duration the ST segment and the QT interval may be measured readily First a multilead QRS detector locates each beat using a dierentiated and lowpass ltered ECG signal as input Next the waveform boundaries are located in each lead The leads in which the detected electrical activity is of longest duration are used for the nal determination of the waveform boundaries The performance of our algorithm has been evaluated using the CSE multilead measurement database In comparison with other algorithms tested by the CSE our algorithm achieves better agreement with manual measurements of the T wave end and of interval values while its measurements of other waveform boundaries are within the range of the algorithm and manual measurements obtained by the CSE

The problem of pattern recognition is discussed in terms of single-entity representation versus multiple-entity representation. A comibined syntactic-semantic approach based on attributed grammars is suggested. Svntax-semantics tradeoff in pattern representation is demonstrated. This approach is intended to be an initial step toward unification of syntactic and statistical approaches to pattern recognition.

An application of the syntactic method to recognition of electrocardiogram (ECG) and to the measurement of ECG parameters is presented. Solutions to the subproblems of primitive pattern selection, primitive pattern extraction, linguistic representation, and pattern grammar formulation are given. Attribute grammars are used as the model for the pattern grammar because of their descriptive power, which is due to their ability to handle syntactic as well as semantic information. This approach has been implemented and the performance of the resultant system has been evaluated using an annotated standard ECG library.

Computer analysis of ECG signals is common today. Devices on the market that analyze ECGs, such as patient monitors, stress test systems, and Holter analysis systems, do a good job of detecting beats and classifying arrhythmias. However, new companies are constantly emerging and applying new technologies, such as PDAs, in an effort to make smaller and cheaper ECG analysis systems. Other companies are using ECG gating to improve imaging of the heart. Each new company that produces a product that requires ECG analysis must implement their own ECG analysis software, duplicating the efforts of every other company. Similarly, researchers who need ECG analysis to explore new diagnostic methods, such as the analysis of heart rate variability, must also implement their own versions of basic ECG analysis functions. Thirty years of research on computer analysis of ECG signals has produced a great many methods for detecting beats and classifying ECG signals, but there is still a significant effort required to go from theory to implementation.

Looking for a way to draw 2D line graphs with C#? Here's yet another charting class library with a high degree of configurability, that is also easy to use.

ZedGraph is a class library, Windows Forms UserControl, and ASP web-accessible control for creating 2D line, bar, and pie graphs of arbitrary datasets. The classes provide a high degree of flexibility - almost every aspect of the graph can be user-modified. At the same time, usage of the classes is kept simple by providing default values for all of the graph attributes. The classes include code for choosing appropriate scale ranges and step sizes based on the range of data values being plotted. Moreover, ZedGraph is compatible with .NET 2.0, and VS .NET 2005. ZedGraph is maintained as an open-source development project on SourceForge. The site includes a project Wiki, documentation, interim (CVS) updates, and all release versions. A set of sample graphs is also available on the Wiki, complete with source code (many of the samples include C# and VB code).

If you have not used any of these programs before, you may need to set up your environment properly so thatWFDB applications can find their input files. See setwfdb(1) in this guide for information about doing this; a more detailed discussion may be found in the first chapter of the WFDB Programmer’s Guide, in the section about the database path.

This guide documents the Waveform Database interface library (the WFDB library), a package of C-callable functions that provide clean and uniform access to digitized, annotated signals stored in a variety of formats. These functions were originally designed for use with databases of electrocardiograms, including the MIT-BIH Arrhythmia Database (MIT DB) and the AHA Database for the Evaluation of Ventricular Arrhythmia Detectors (AHA DB).

Scrum基于业界认可的最佳实践，这些实践已在过去的几十年被使用并证实有效。之后，Scrum被置于基于经验过程的理论中。正如Jim Coplien一次对Jeff所说：“每个人都会喜欢Scrum；因为这是当我们被逼到墙角时的自然反应。”
