The IP Multimedia Subsystem (IMS) is a key component in the Mobile Next Generation Network, which is used by telecommunications operators throughout the world to provide access to multimedia and broadband services. As these services become more sophisticated, and as the number of clients rises drastically, it is increasingly expensive to install and operate a network that will satisfy the users' expectations. Cloud computing combined with high-speed networks provides a potential method for reducing the installation and operational costs of IMS. However, their use may introduce performance degradation in certain parameters, such as the delay. We will construct a test environment that will permit us to model a cloud-based IMS system, after determining which components of IMS could benefit from this approach. Successful adaptation of IMS to the cloud-based environment will permit telecommunications operators to improve the availability of their Application Servers, which will enhance the user experience.

The Probiotics and Mental Health Research Lab in the Psychology Department at Acadia University is currently involved in exciting and innovative research examining the benefits that probiotics (a type of beneficial bacteria found in the human digestive tract as well as in certain foods) may provide to individuals living with psychological conditions such as anxiety, depression, and ADHD. While it is already well documented that probiotics promote good digestive health, less is known about the effects of probiotics on psychological health. Lallemand Health Solutions has recently developed a technique to microencapsulate probiotic bacteria so that they are better able to survive stomach acids on their way to the intestines where they exert their beneficial effects. Dr. Susan Potter and Acadia graduate student, Anne Baccardax, plan to investigate the effectiveness of Lallemand’s “Probio’Stick”, a probiotic supplement, in alleviating symptoms of anxiety and ADHD in children. These mental health conditions can significantly impact a child’s quality of life. Research demonstrating that probiotics are an effective and natural treatment for these conditions could lead to tremendous benefits for these children.

The proposed research aims to find the optimal application rates of liquid chemicals which are applied to a road surface before and during a snow storm. These chemicals are used to accelerate the melting of snow and ice. The effects of various factors such as traffic, pavement temperature and other environmental factors on the performance of these chemicals will also be investigated. In addition, alternative types of machinery currently used to distribute solid chemicals on the roadways will be compared to examine their effectiveness. Existing research in the use of both liquid and solid chemicals will be summarized and a survey of maintenance practices of different municipalities will be conducted and the results documented and compared. The partner organizations will benefit from the knowledge generated from this research with improved decision making on their winter road maintenance operations and reduced salt usage.

In aviation industry a large flow of data including thousands of parameters are registered by FDRs (Flight Data Recorders). The objective of this project is to use this big data to improve the efficiency and safety of flights. The data is collected and segmented from the raw datasets and then proper data cleaning methods are used to preprocess data. Then, by the help of analytical models we define a baseline for different registered parameters and compare individual flights against the baseline to detect anomalies. In the next step, by the help of optimization models and statistical techniques such as clique partitioning and set partitioning methods, we define a normal flight and compare individual flights with this pattern.
Amélioration du bilan nutritif de la chicouté par fertilisation et enracinement hâtif des rhizomes transplantés
La Mousse Acadienne (1979) Ltée
La chicouté est un petit fruit qui pousse naturellement en tourbière et sa mise en culture dans des tourbières abandonnées après exploitation de la tourbe permettrait de poursuivre des activités économiques, tout en restaurant le milieu. Son implantation demeure cependant problématique. La culture se fait à partir de segments de rhizomes qui sont souvent dépourvus de racines. Un des volets du projet vise à identifier un fertilisant qui accélérerait la production de racines. Un deuxième volet vise à identifier les nutriments qui limitent la production de fruits. Le troisième volet consiste en un suivi de parcelles plantées il y a plus de dix ans selon différentes pratiques culturales, afin d’identifier les facteurs qui influencent le rendement en fruit à long terme. Ces trois volets permettront de mieux caractériser les conditions nécessaires pour établir une culture rentable de chicouté en tourbière abandonnées après exploitation de la tourbe.

Malgré le peu de considération portée aux impacts du gel en conception de chaussées rigides, il est connu qu’elles sont sensibles aux variations de température. Les gradients de température entre le haut et le bas des dalles font en sorte qu’il peut y avoir apparition de fissures transversales et de fissures aux coins (Harvey, 2004). Cependant, à notre connaissance, aucune méthode de dimensionnement de chaussée rigide, ni aucune norme ne considèrent les impacts du soulèvement, par l’effet du gel, de la structure de chaussée autre que celle déjà utilisée pour les chaussées souples. Or, la rigidité même des matériaux constituants les chaussées souples et rigides est très différente d’un point de vue thermomécanique entraînant par le fait même une différence dans leur réaction aux forces dues au soulèvement par le gel. L’objectif principal de ce programme de recherche est d’évaluer le comportement des chaussées rigides au gel afin de mieux comprendre les forces en jeux dans ces conditions.
The impact of a serious mobile video game on girls’ perceptions, attitudes and behaviors about global water issues and education
We want to learn about the video game “Get Water!” at the Linden School for Girls in Toronto with students between the ages of 10 – 14, from their perspective. This research will involve their teachers and parents as co-researchers who will be asked to keep a journal for two weeks about anything the girls may say directly about the game, or about global water issues or girls education, or anything the girls may do in relation to the game or water issues, for example research on the internet about water or girls education. We are interested in parental response, as well as their daughters response to the game and we are wondering about the potential for social impact of the game. By social impact we wonder whether the game affects attitudes, perceptions or behaviours in relation to water issues and/or girls’ education, or games in general, or do the participants simply think of the game as just a game? Can the game be used as a tool to raise awareness in young Canadian girls about global water issues and the effects on girls’ education?

This research looks to explore the collaboration of ecology, education and design in the creation of built and natural systems to sustainably manage and educate about storm/rain water on school grounds. The research will be conducted through the analysis of 3 key case studies of schoolyard storm/rain water management projects that represent a successful, progressive and collaborative approach to the design, implementation, use and maintenance of the schoolyard water management system. The results of the case study analysis will be used to inform a pilot project to be undertaken at a school in Victoria, BC. During the main research period I will be doing 2 Mitacs internships with Murdoch de Greeff, a Victoria based company specializing in urban storm/rain water design and landscape architecture. Murdoch de Greeff will contribute hands-on professional knowledge to the research process, in turn they will benefit from the results of the research as professional development. By participating in this research Murdoch de Greeff will also be well poised to take on schoolyard design projects as more schools look to improve the water management and outdoor educational environments on their school grounds.

This project aims to investigate the benefits of using linguistic cues for extracting speech-ofinterest from competing background noise. Given an algorithm which detects formants of a speaker of interest within an audio signal which includes background noise, and given that the limits of such an approach are reached when formants of the speaker of interest become substantially lost within the noise, are there linguistic cues within some formants, or linguistic relationships between some successive speech sounds, which can be used to infer with confidence which speech sounds from the speaker of interest are present beneath the noise floor of a noisy audio signal. The partner organization will benefit from this internship by extending the range of solutions it can offer to the market. If the proposed solution proves to be useful and novel, the partner organization will apply for patent protection. This could lead to increased sales and the additional employment within the company.

Osmotic power or salinity gradient energy is one type of the renewable energies which is produced by mixing fresh water with salt water. This new environmental friendly energy based on the advantages such as carbon dioxide free and generating power continuously seems to be a good option in which to invest as it will be highly beneficial to Quebec. This project looks to develop expertise related to osmotic power. A pressure retarded osmosis (PRO) power test unit will be designed and installed in Quebec. This will be the first osmotic power system in North America. The project will consist of evaluation and selection of sites for potential pilot testing, determination of pretreatment and cleaning requirements for the membranes, and subsequent design of the test unit. This will provide hands on experience related to the design and operation of a PRO power system in Quebec and enable the evaluation of the viability of this technology for future development for the interns.

From my perspective, the true value of the Mitacs-Accelerate internship is the individual relationships developed with people working for the industrial partner. Through the internship, although I became more familiar with methods, ideas, and technical issues related to my area of research, it was the networking experiences that I found to be most rewarding. I have no doubt that these relationships will continue to be of value throughout my career.
