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.
Emerging applications such as interactive video conferencing, Voice over IP (VoIP) and cloud computing are required to achieve an end-to-end latency of less than 200 milliseconds. In many wireless networks, the round-trip time can alone reach this limit. Hence it is necessary to develop new delay-optimized networking protocols and delay-sensitive coding techniques in order to meet such stringent delay constraints. The proposed project will investigate both theoretical foundations and practical implementations to reduce delays in interactive communication scenarios.
Le projet porte sur le développement des algorithmes permettant de transporter d’une façon stable, par deux robots humanoïdes Nao, une table miniature dans un environnement encombré. Plusieurs étapes sont nécessaires pour arriver à ce résultat. En premier lieu, il est essentiel de compenser les perturbations causées par les oscillations latérales dues à la marche bipède. Puis, une planification de trajectoire de marche doit être effectuée afin de faire naviguer les robots dans l'environnement encombré.
The main objective of the proposed research project is to develop a new transient stability simulation method based on advanced computational and modeling techniques that is both fast and accurate. Transient stability studies are an important part of system planning and operation as they ensure that a system will maintain stable operation following severe disturbances. However, traditional simulation techniques were not designed for the size and complexity of modern power systems.
Many big data challenges are characterized not only by a very large volume of data that has to be processed but also by a high data production rate. In this project, new storage approaches for big data will be explored. Key point is the efficient use of modern hardware, especially modern storage technology such as SSDs. These new technologies have highly improved performance in comparison to traditional hardware. However, classical data structures and algorithms can not directly be applied due to the different characteristics of these devices.
Unlike centralized computing, which is typically performed in a single data-center, Cloud computing enables the computation to be spread across multiple geographically distributed data-centers which are abstracted as a single system by the Cloud management layer. This computational model enables disaster recovery (DR) by re-establishing the services provided by a data-center affected by the disaster in another healthy data-center capable of hosting the applications providing these services.
Pour tester les contrôleurs électriques dans les domaines tels que les systèmes de puissance, l’aéronautique et l’automobile, on doit réaliser des simulateurs temps réel des moteurs et d’autres dispositifs électriques afin de s’assurer de leur bon fonctionnement et de leur sécurité dans diverses circonstances (ex. la foudre qui frappe une ligne de transmission ou un avion). Par ailleurs, ces simulateurs doivent réagir très rapidement aux commandes (de l’ordre du millionième de seconde).
Avertus Epilepsy Technologies Inc. is building a wireless headset that records brain waves (EEG) without requiring extensive, time-consuming, and uncomfortable patient preparation. Avertus’ SMART (Seizure Monitoring at the Right Time) Headset is a patient focused, point-of-care monitoring and detection system. Worn during the day or just at night during sleep, the SMART Headset represents safety, response when needed, and peace-of-mind. For drug companies and treating physicians, the SMART Headset provides an objective measure of seizure occurrence to assess drug efficacy.
The market share of online advertising, also known as Internet advertising, has been increasing dramatically in recent years. On the other hand, malicious behaviors, such as click fraud, have degraded the effectiveness of online advertising. Via fraud clicks, a considerable amount of revenues have been lost to fraud conductors. For instance, based on a report published by PricewaterhouseCoopers, click fraud accounts for as much as 36% of all advertising clicks, which costs defrauded advertisers hundreds of millions of dollars annually.
