Le projet consiste à développer un modèle 3D pour modéliser les phénomènes électromagnétiques et thermiques permettant de simuler les effets déchauffements dus à des courants de Foucault, i.e. des courants électriques induits par des variations temporelles dun champ magnétique.
L'objectif du projet est de développer une stratégie de contrôle dans le cadre de la conception d'un convertisseur électronique DC-DC modulaire dédié à la conversion de l'énergie solaire. Le partenaire de recherche Convertronix est une entreprise en plein développement et le projet de recherche en collaboration avec l'ETS permettra à l'entreprise d'acquérir et consolider rapidement une expertise dans le domaine de l'énergie solaire.
Reducing energy consumption is one of many ways to respond to our urgent global need to reduce carbon dioxide (CO2) emissions. To do so, it is important to identify the most effective energy saving strategies and communicate them to energy consumers. Pulse Energy is a company that works to do just that and is always looking to improve their energy saving recommendations.
The current EyesIQ system has a few limitations in terms of performance and accuracy:To be able to stitch images from a 2D microscope slide, the 2D position from one image to another needs to be calculated. This process is called image registration. However, inaccuracy in the image registration algorithm introduces a slight error in calculated image position. As more images are being stitched together, the image registration error accumulates. For example, the image position error is more noticeable when the path of the images form a loop.
The proposed project aims at the design and implementation of low complexity digital pre-distortion (DPD) algorithms for multiband and multiple input multiple output (MIMO) wireless transmitters. The power amplifier (PA) is one of the major sources of power dissipation in wireless base stations. The DPD techniques enable the PA to operate in a more efficient power level resulting in more energy efficient wireless networks.
The cellular network nowadays faces an uphill battle against the explosive growth of mobile data traffic. Deploying low power radio base stations covering small cells within the current cellular coverage area is a promising approach to significantly boost the network capacity, provide better coverage, and reduce network congestion.
One of the major bottlenecks in portable devices is the limited energy provided by batteries. Some devices can afford larger battery packages and thus extend their battery longevity. However, for small portable units such as Recon Instrument's sport goggles, using larger batteries is not feasible. This research is mainly focused on remote charging for separation distances of up to 50 cm. It will lead to design and implement a dual-mode (hybrid) wireless power transfer system that is capable of both providing a "top-up" power as well as recharging the battery of the portable units.
The proposed internship aims to study how the characteristics and reliability of Permanent Magnet Electric Motors (PMs) affect their life-cycle cost (LCC), including initial, maintenance, and energy costs. First, the effect of the variation of design variables on the performance and initial cost of PMs will be assessed and the cost will be correlated to performance. Second, the effect of materials and processes on the reliability and the LCC of PMs will be studied and LCC will be correlated to reliability. The results will be presented to TM4 in form of a detailed database.
Energy saving is one of the important issues in today world. In order to improve the performance of the industrial motor drives for high-power applications, higher voltage power converters are recommended. Compared with low-power converters, high-power systems have their distinct characteristics and challenges, and usually require converter configurations capable of processing energy conversion at higher power and voltage levels. The technical requirements and challenges for MV systems differ in many aspects from those of the low-voltage AC converters, which have been mostly resolved.
Fiber Bragg gratings (FBGs) have attracted considerable interest in the past three decades as a key technology in different applications. The intention of this project is to develop a FBG writing technique based on a scanning tunable Phase-Mask Interferometer using different UV lasers. The project includes optimizing the tunability of the interferometer, and analyzing the specific problem situations encountered in the process in order to develop the interrogation methods of the proposed technique.
