We test a method of clustering dialects of English according to patterns of shared phonological features. Previous linguistic research has generally considered phonological features as independent of each other, but c...

the process we propose in this paper is in keeping with a more general thought about e-learning systems reengineering. It deals more precisely with pedagogical scenario reengineering by assisting designers in the uses tracking definition phase in order to allow them to a posteriori understanding of the learning session sequence. From this point of view, our process presents some advantages. First, it allows the recommendation of uses to track from the designer built scenario structure. then, it proposes a formal way to transcribe these observed uses in a design interpretable language, and thus to compare a priori scenario to the one resulting from a posteriori observed uses. Lastly, it relies on an analysis at a meta-model level of the pedagogical modeling language chosen by designers and, therefore, allows complete dissociation from a chosen language.

Withthe recent growth of interest in microarray technology and the improvement of the technology responsible for producing these images, massive amounts of microarray images are currently being produced. In this paper, we present a new lossless method for efficiently compress microarray images based on arithmetic coding using a 3D context model. Our method produces an embedded bitstream that allows progressive decoding. We present the compression results using 49 publicly available images and we compare these results withthree image coding standards: lossless JPEG2000, JBIG and JPEG-LS. the proposed method gives better results for all images of the test set.

context-awareness has become a necessity for adaptable intelligent applications and services. It is crucial for ubiquitous and pervasive computing because the context of a user or device serves as the source of information to adapt services. In this paper, we propose a modular context management system that is able to collect, transform, reason on and use context information to adapt services. By employing a component-based approach, we enable our infrastructure not only to support context-aware adaptation of services, but also to support adaptation of the context management system itself at deployment time and at runtime. this self-adaptation is based upon the service requirements and the current context of the device, such as the current resource usage or other devices in the neighborhood, resulting in an adaptive context management system for improved quality of service.

the volume of Internet spam has reached alarming proportions. this raises interesting debates on a variety of ethical, social, legal and technical issues. Although a fair amount of spam research has been conducted in the developed world, the socioeconomic context and technical infrastructure in South Africa is more typical of a developing world and many issues take on new dimensions. this research used a survey to obtain the perceptions of e-mail users on various social and ethical issues regarding spam. Information about the legal and technical issues was gathered using structured face-to-face interviews with six ISPs. the research confirms the typical findings about the high levels of spam, the nuisance factor, the invasion of privacy and cost in terms of time and bandwidth. However, it was also found that that many users find different types of spam morally very offensive. While Bayesian and open source spam-filtering mechanisms are in place at South African ISPs, spam levels are about the same as in Europe and North America. Also, ISPs found that the recently promulgated South African ECT Act fails to deal conclusively with spam.
