Independent Component Analysis (ICA) is a multivariate data analysis process largely sudied these last years in the signal processing community for blind source separation. This paper proposes to show the interest of ICA as a tool for unsupervised analysis of hyperspectral images. The commonly used Principal Component Analysis (PCA) is the mean square optimal projection for gaussian data leadin...

Electronic newspapers are now becoming available via wide-area computer networks, such as the internet. Unfortunately, the Windows-based graphical user interface of the client programs makes it difficult for visually impaired people to use such services. Furthermore, few visually impaired people have a PC. The AUDIOMAT project was designed to provide a reading system for the visually impaired, ...

Method: A total of 258 children and adolescents (46.51% boys) aged 8-18 years (Mean±SD: 12.66±2.73) and their parents were recruited from a community sample. For each pair of child-parent, the child and one parent were interviewed separately by an interviewer using the CASDI and by a second blind interviewer using the DSM-5 Pediatric Diagnostic Interview one week after the CASDI administration....

Problem statement: Map creation remains a very active field in the robotics and AI community, however it contains some challenge points like data association and the high degree of accuracy of localization which are seems to be difficult in some cases, more than that, most of these study focus on the robot navigation, without any consideration for the semantic of the environment, to serve human...

impairment Changing demography When the Community Eye Health Journal was launched in 1988, the world population was approximately 5.1 billion. Over the last 20 years, it has increased by approximately 30%, reaching 6.7 billion in 2008. During the same period, the world population has also become proportionally older, as the number of people aged 65 years and over has increased by approximately ...

We report the development of a novel high performance computing method for the identification of proteins from unknown (environmental) samples. The method uses computational optimization to provide an effective way to control the false discovery rate for environmental samples and complements de novo peptide sequencing. Furthermore, the method provides information based on the expressed protein ...

A number of conditions are necessary for the formation of ‘glue’ to keep an online community together. One condition of the ‘glue’ is community knowledge. We describe a theoretical basis and a practical representation framework on which community knowledge can be built and used. An illustrative example is given and further work noted.
