Knowledge Creation Analytics for Online Engineering Learning
… written documents and discussion archives by engineering learners seeking to expand their learning and advance their knowledge beyond the engineering classroom. However, it remains a challenging task to assess the quality of knowledge advancement on these learning platforms particularly due to …

Development of an RF listening mode on the TIGER-3 FPGA platform
High frequency (HF) radars have many critical applications due to the effects that physical media have on the wave's propagation. The diffraction of HF radio waves in the ionosphere allows for long range communication and radar operation. Waves travel over the horizon where they may be reflected …

Absolute electrical impedance tomography and spectroscopy: an Orthogonal Chirp Division Multiplexed (OCDM) approach
Absolute Electrical Impedance Tomography and Spectroscopy (aEITS) is a non-intrusive imaging technique, that reconstructs images based on estimates of the absolute internal impedance distribution of an object. However, without the availability of a reference frame, it suffers from poor image …

High-Speed Organic Photodetectors for Visible Light Communication
… characteristics that surpass conventional rigid electronics. In recent years, visible light communication (VLC) has attracted considerable interest for use in in-home and sensor networks. Organic optoelectronic devices such as organic light-emitting diodes (OLEDs) and organic photodetectors …

Model Order Reduction: Application to Electromagnetic Problems
With the increase in computational resources, numerical modeling has grown expo- nentially these last two decades. From structural analysis to combustion modeling and electromagnetics, discretization methods–in particular the finite element method–have had a tremendous impact. Their main advantage …

On-line Dynamic Security Assessment in Power Systems.
The thesis concerns the development of tools and methods for on-line dynamic security assessment (DSA). In a future power system with low-dependence or even independence of fossil fuels, generation will be based to a large extent on non-controllable renewable energy sources (RES), such as wind and …

Audiovisual spatial congruence, and applications to 3D sound and stereoscopic video
While 3D cinema is becoming increasingly established, little effort has focused on the general problem of producing a 3D sound scene spatially coherent with the visual content of a stereoscopic-3D (s-3D) movie. The perceptual relevance of such spatial audiovisual coherence is of significant …

Modélisation du comportement non-linéaire d’un haut-parleur pour sonorisation instrumentale
Pour un guitariste, le haut-parleur qu’il utilise fait partie intégrante de sa chaı̂ne d’instrumentation, au même titre que son ampli, ses effets ou sa guitare. Le haut-parleur agit comme un filtre constitué d’un grand nombre de subtilités qu’il est fort difficile de copier même à l’aide d’un …
