In this paper, two strategies to compute the support sets system for the supervised classifier ALVOT (voting algorithms) using sequential floating selection are presented. ALVOT is a supervised classification model based on the partial precedence principle, therefore, it needs, as feature selection, a set of features subsets, this set is called support sets system. The sequential floating selec...

In this paper, a new method named modular multi-directional two-dimensional principle component analysis (MD2DPCA) is proposed for face recognition. First, the original images are rotated at some predetermined angles so that we may extract features from the images in any direction. Then we divide the rotated images into smaller sub-images and apply 2DPCA approach to each of these sub-images. Fi...

3-D Networks-on-Chip (NoCs) emerge as a powerful solution to address both the interconnection and design complexity problems facing future Systems-on-Chip (SoCs). Effective run-time application mapping on a 3-D NoC-based Multiprocessor Systems-on-Chip (MPSoC) can be quite challenging, largely due to the fact that the arrival order and task graphs of the target applications are not known a prior...

A sample return mission, as the name suggests, involves sampling some interesting feature of an environment and returning this to some home base. Research in this area is overwhelmingly geared towards space exploration. This is due to the fact that planetary sampling can provide key information for understanding the solar system evolution and addressing the questions such as habitability and pr...

This paper reports recent work at ORL on segmentation of digital audio/video recordings. Firstly, we describe an audio segmentation algorithm that partitions a soundtrack into manageably sized segments for speech recognition. Secondly, we present an algorithm for detecting camera shot-break locations in the video. The output of these two algorithms is combined to produce a semantically meaningf...

A Cabin Car Communication System (CCCS) has the goal of improving the communication among passengers inside the car. Wind, road and engine noise, the distance between passengers and other factors make difficult the communication inside vehicles. The driver must often look away from the road and passengers move out of normal seating positions. The CCCS makes use of a set of microphones to pick u...

Many large-scale stochastic systems, such as telecommunications networks, can be modelled using a continuous-time Markov chain. However, it is frequently the case that a satisfactory analysis of their time dependent, or even equilibrium behaviour, is impossible. In this paper we propose a new method of analyzing Markovian models, whereby the existing transition structure is replaced by a more a...
