The competence of an engineer and how it is build through an apprenticeship programme: a tentative model
This paper presents some findings resulting from a four-year research aiming to identify what competence are developed by students following an apprenticeship program in engineering and what the developmental steps are in conjunction with the curriculum. The main findings presented here suggest: 1) that competence has three dimensions; 2) that the competence framework of an […]

Efficient Codebooks for Fast and Accurate Low Resource ASR Systems
Today, speech interfaces have become widely employed in mobile devices, thus recognition speed and resource consumption are becoming new metrics of Automatic Speech Recognition (ASR) performance. For ASR systems using continuous Hidden Markov Models (HMMs), the computa-tion of the state likelihood is one of the most time consuming parts. In this paper, we propose novel […]

Speech transcription for Embodied Conversational Agent animation
This article investigates speech transcription within a framework of Embodied Conversational Agent (ECA) animation by voice. The idea is to detect some pronounced expressions/keywords in order to animate automatically the face and the body of an avatar. Extensibility, speed and precision are the main constraints of this interactive application. So after defining the set of […]

Growth of Amorphous Ti–Si–O Thin Films by Aerosol CVD Process at Atmospheric Pressure
We present the deposition of amorphous thin films by an aerosol chemical vapor deposition process at atmospheric pressure. We used di-acetoxi–di-butoxisilane, tetrabutoxysilane, and titanium(IV) -butoxide as precursors, and the deposition temperatures ranged from 475 to 675°C. During the deposition process a chemical reaction between the different precursors took place. We found a synergetic mutual influence […]
