This paper presents a multi-robot mapping and localization system. Learning maps and efficient exploration of an unknown environment is a fundamental problem in mobile robotics usually called SLAM (simultaneous localization and mapping problem). Our approach involves a team of mobile…

This paper describes the design of an autonomous blimp-based robot and its navigation system. The robot was based on a commercial kit and its dimensions were suitable for use in indoor environments. Our main goal was to develop a simple…

Photographic emulsions are still widely used to record holographic optical elements. In particular, if high diffraction efficiencies are needed, phase volume holograms are preferably recorded on these emulsions. Two particular techniques producing high-quality volume phase holograms are fixation-free rehalogenating bleaching…

Real-time holographic interferometry has been used to visualize the evolution of the polarization layer during dead-end ultrafiltration of PEG-10000. Several experiments at a constant pressure of 1 bar and varying the feed concentration of PEG-10000 (5–12.5 kg/m3) have been carried…

Human-Robot Interaction (HRI) is one of the most important subfields of social robotics. In several applications, text-to-speech (TTS) techniques are used by robots to provide feedback to humans. In this respect, a natural synchronization between the synthetic voice and the…

The advent of performance metrics over the past two decades has heralded a cultural shift in
the way public service bodies and institutions have been managed. As a result, all public
service provision is now subjected to government led performance…

Ce manuscrit est une pré-publication d'un article paru dans The American Journal on Addictions 2010; 19(3): 231-237 url: http://onlinelibrary.wiley.com/doi/10.1111/ajad.2010.19.issue-3/issuetoc, IRSC et FRSQ - Réseau SIDA et maladies infectieuses

In this paper we analyze a simple experiment to study the effects of polarized light. A simple optical system composed of a polarizer, a retarder (cellotape) and an analyzer is used to study the effect on the polarization state of…

Purpose – Given the proliferation of United Kingdom (UK) media headlines around the recent financial meltdown and the subsequent allocation of blame to government, bankers, the Bank of England and the Financial Services Authority, it is clear that there is…
