IP multimedia subsystem has been identified by mobile network operators as a promising framework for deploying VoLTE and rich communications services. Offering these services in efficient manner makes it even more attractive. Virtualization represents the suitable concept to achieve this. Moreover, deploying IMS in virtualized environment becomes a solution of great potential especially for multi-tenant application providers. This project aims at defining and validating elasticity management approaches of virtualized IMS based on SLA.
The amount of emissions to the atmosphere is currently an important environmental concern as policy makers and Heads of State are starting to demonstrate a strong interest in energy efficient transportation, in particular energy efficient aircraft. However, current autopilot technology will often not take into account the energy used to perform a given maneuver which can lead to potentially larger fuel consumption and larger atmospheric emissions than what is strictly necessary. The task of energy optimization is typically left to a flight management system (FMS).
The rapid technological evolution of telecommunication networks demands service providers to regularly update their technology, with the aim of remaining competitive in the marketplace. However, upgrading the technology in a network is not a trivial task. When modernizing a network, the existing infrastructure and network components need to be taken into account. The design exercise must not only take into consideration the overall desired functionality and capacity but also the existing network properties.
Digital Pathology provides a great reliable source for cancer diagnosis; however, this relatively new technique lacks an appropriate method of regulation and standardization. As a result the information obtained from cancer imaging system might suffer from inconsistency of the results (repeatability and reproducibility issues). Working with the BC Cancer Research Center, Logipath Medical Inc. has developed a number of quantitative pathology systems some of which have been spun off to commercial entities.
The number of biomedical scientific publications available in multiple repositories is huge and rapidly growing. As of April 2014, PubMed, the largest knowledge source for biomedical and life science literature, comprises more than 23 million citations. Querying PubMed with the keyword HIV provides a list of almost three hundred thousand citations. Retrieving data of particular interest for a specific research field in such a large volume of publications is often like looking for a needle in a haystack.
The advent of smartphones and the associated change in usage patterns indicates that carrier voice revenues are constantly going down and are expected to almost vanish in the near future. Data revenues are picking up but not at a rate which will make up for the shortfall in voice revenues. Also, the increase in data revenue is accompanied by a corresponding increase in traffic. This leads to higher costs in deploying and operating networks as well as a significant growth in network complexity. In this project we will be working on
A camera is a device that captures light from scenes. Over the last century, the evolution of cameras has been truly remarkable. Through this evolution, the underlying camera has been improved by using a better optical lens. However, the new improved optical lenses, have been remained fixed in terms of size and weight which makes it hard to use in portable devices. In contrast to optical trend, according to Moore’s law, the number of transistor in the chip doubles approximately every two years. This leads to a huge improvement in computational devices.
The project concentrates on MEMS (Micro-Electro-Mechanical Systems) fabrication process optimization. MEMS devices comprise suspended structures, such as cantilevers, gyros, membranes, etc., which are created by removing sacrificial material around them in order to have these structures released to perform their designated function. Currently, these structures are being released with the use of either dry etch or chemical vapor techniques. Wet chemistry release of suspended structures is favorable: minimized costs, parallel process and most importantly reduced impact on the environment.
The electromyography (EMG) signals are biological signals, which are related to the electrical activity produced by skeletal muscles. To measure and analyze EMG signals, we will use noninvasive EMG surface electrodes. The EMG signals allow knowing the intention of the movement before that the movement happens; this is because of the electromechanical delay of the muscle. The proposed project would exploit this property to generate humanoid robot movements in order to interact properly with a human being.
Mon stage au sein du laboratoire de microélectronique (LME) du département des systèmes électroniques (PSI) de l’École polytechnique de l’Université de Sao Paulo, (EPUSP) sera d’une durée de quatre mois. Mon mandat sera de développer un dispositif (coupleur) qui sera utilisé dans des systèmes de communication sans fils à courte distance (quelques mètres). Le matériau (substrat) utilisé pour concevoir ce couleur relève d’une technologie développer et breveté par le groupe de recherche du LME en collaboration avec un partenaire français.
