Effort, co-operation and co-ordination in an open source software project: GNOME

Abstract This paper presents results from research into open source projects from a software engineering perspective. The research methodology employed relies on public data retrieved from the CVS repository of the GNOME project and relevant discussion groups. This methodology is described, and results concerning the special characteristics of open source software development are given. These data are used for a first approach to estimating the total effort to be expended.     

Simulation of cardiovascular system diseases by including the autonomic nervous system into a minimal model

Diagnosing cardiovascular system (CVS) diseases from clinically measured data is difficult, due to the complexity of the hemodynamic and autonomic nervous system (ANS) interactions. Physiological models could describe these interactions to enable simulation of a variety of diseases, and could be combined with parameter estimation algorithms to help clinicians diagnose CVS dysfunctions. This paper presents modifications to an existing CVS model to include a minimal physiological model of ANS activation. A minimal model is used so as to minimise the number of parameters required to specify ANS activation, enabling the effects of each parameter on hemodynamics to be easily understood. The combined CVS and ANS model is verified by simulating a variety of CVS diseases, and comparing simulation results with common physiological understanding of ANS function and the characteristic hemodynamics seen in these diseases. The model of ANS activation is required to simulate hemodynamic effects such as increased cardiac output in septic shock, elevated pulmonary artery pressure in left ventricular infarction, and elevated filling pressures in pericardial tamponade. This is the first known example of a minimal CVS model that includes a generic model of ANS activation and is shown to simulate diseases from throughout the CVS.     

Computer Vision Syndrome: A widely spreading but largely unknown epidemic among computer users

The present paper is intended to introduce behavioral researchers to Computer Vision Syndrome (CVS), a widely spreading but largely unknown epidemic among professional and ordinary computer users, and to call for behavioral research programs to help computer users address this visual epidemic. Beginning with three clinical cases, the paper analyzes the classic definition of CVS, discusses the prevalence of CVS, reviews five major symptoms of CVS (i.e. eyestrain, headache, blurred vision, dry eyes, and neck/back pain), summarizes five types of contributing factors of CVS (i.e. computer screens, computer environments, human eyes, computer users, and computer tasks), and presents basic preventive and treatment strategies. Finally, three future research directions for behavioral science research are briefly discussed.     

InterNetNews server: inside an open-source project

What do you get when you give your source code away and encourage programmers around the world to make changes to it? Some Internet software development engineers believe you get a robust system with a large market share and development that is highly responsive to user needs. The team behind the InterNetNews Usenet server package is one such group of believers. INN provides programs to exchange Usenet messages with other servers and to deliver those messages to end users. The Internet Software Consortium oversees the INN and has been supporting its development under an open model. INN is a moderate-sized software project with more than 430 files containing nearly 150,000 lines in the uncompiled distribution. Programs are written mainly in C, Bourne shell, and Perl. The CVS revision control system manages all changes to files. The paper describes the logistics of InterNetNews     

压缩视频感知中量化器的研究与设计

压缩视频感知（Compressed Video Sensing,CVS）是一种利用压缩感知（Compressed Sensing,CS）以及分布式视频编码（DVC）的视频压缩方法,故又被称为分布式视频压缩感知。在CVS中,每帧图像经过块划分、压缩采样后对数据进行DPCM,最后使用均匀或者非均匀量化进行量化。目前,CVS量化器的设计大多是在采样数据或残差数据服从高斯分布的前提下设计的,通过Kolmogorov-Smirnov检验进一步分析压缩采样后的数据,利用劳埃德最佳量化器准则训练量化码书,设计出一种简单、高效的量化器。经实验,设计的量化器相比于传统的量化方法在BD-Rate上减少了约14.2%,在BDPSNR上提升了约0.11?dB,提高了CVS的压缩效率和重建质量。     

New tricks: how open source changed the way my team works

A commercial software team contributed to an open source implementation of the Windows API on X-Windows and Unix. Wine is an open source implementation of the Windows API, a compatibility layer that lets native windows programs run on X-Windows and Unix. With our contribution filling in some gaps, our client planned to include Wine with a slightly modified product. Expecting chaos in the organization and code, the team instead found a structured community with procedures all its own. The version control tool on the Wine team is CVS (concurrent version system), an open source, network-transparent version control system. Patches on Wine are relatively small, which makes them easier to review and less risky to add to the source tree.
