To optimise business processes is a very complex task. The goal is double: to improve productivity and quality. The method, developed in this paper, is composed of 4 steps : the first one is the modelisation step (to describe the business process in a very rigorous way), then a conceptual optimisation (supported by evaluation and simulation tools) to improve the business process structure (to m...

We present high angular resolution (2.5′′) interferometric images of 13CO J = 1→ 0 , C18O J = 1→ 0 , and λ 2.7 mm continuum emission around L1157-mm, a suspected protostar powering an energetic molecular outflow. The continuum emission consists in two distinct components. The Class 0 object L1157-mm is seen as a compact source of size ≤ 1′′ (440 AU) and mass ' 0.2M , which is marginally resolve...

F0-declination : a comparison between French and German journalistic speech The aim of the present study is to investigate F0-declination over the course of utterances in French and German journalistic speech by using large transcribed and automatically segmented corpora (a total of about 80,000 utterances of more than 1,000 speakers). Two different methods were applied : (i) regression-analysi...

Computer equipment and technology based environment intended for education and training using new communication and information technologies (ICTs) contribute to the modification of the contexts of teaching and learning. We present a study concerning the learning of physics (mechanics) while using the ‘PHYSICS BY IMAGE’ AND ‘MODELSCREATOR’ technology based learning environments.

Original methods of radar detection performances analysis are derived for a fluctuating or non-fluctuating target embedded in additive and a priori unknown noise. This kind of noise can be, for example, the sea or ground clutter encountered in surface-sited radar for the detection of target illuminated at low grazing angles or in high resolution radar. For these cases, the spiky clutter tends t...

Agent based and cellular automata models have been widely used in an efficient as well as effective way in context of studying granular traffic, but rare are those which consider the combined effect and interactions of pedestrians and vehicles in the urban network. So from this poit of view we are proposing here a whole new approach of studying urban complexities. A new GOALSim model is propose...
