Machine Learning Techniques for Speech Enhancement in Audio Conferencing Systems

The core value of Nureva is to provide reliable and easy-to-use audio-conferencing products that offer a good user experience and maximize productivity. A very important factor of that is to output clean audio which oftentimes in its raw form is contaminated with environmental noise, reverberation, and echo. These problems have been researched using traditional signal processing methods for a long time. While these can be quite effective in many situations, they do have limitations with non-stationary noises that vary with time. The success of Machine Learning (ML) in various fields also unlocks new possibilities in noise suppression and speech enhancement in that manual feature engineering is reduced or eliminated. That allows ML models to generalize to situations it has not encountered in training. This research aims to investigate the merits of various ML techniques and how they can be applied with Nureva products to ensure better audio performance.

Effects of sow grouping practices on reproductive performance and piglet development in relation to prenatal stress

After being bred, sows are commonly housed in individual stalls, which restricts their movement and impacts their well-being. For this reason, Canadian farmers are transitioning to housing sows in groups where sows have social interaction and greater movement. Groups can be formed right after breeding, with either a constant group (static: the same sows remain together until farrowing) or with smaller groups of sows being periodically removed and replaced (dynamic). While group housing allows sows greater movement and ability to socialize it can also compromise welfare by increasing aggression and stress, particularly in subordinate sows, if not properly managed. Stress on the sow can also impact the development of piglets in utero, potentially affecting the quantity and quality of pigs produced and piglets’ behaviour, immune system and physiology later in life. This study will compare the stress that sows experience in static and dynamic groups, and study the effects their piglets. The results will be used to assist pig producers in implementing better sow grouping practices that can decrease stress and improve production outcomes.

Our holistic training model engages users in personalized, evidence-based development by utilizing 360-degree assessment, microlearning, on-the-job practice, behavioural nudges, real peer feedback, and the first-hand knowledge that lives outside of textbooks, all with the goal of driving measurable and lasting behaviour change. This project will help Monark address the current challenges of the iteration and expansion of the product in its early form, by focusing on the collection, analysis and interpretation of early data trends and habits from our pilot users.

Statistical Analysis of Prostate Brachytherapy Treatment Data

Using data obtained over a period of 15 years from Brachytherapy procedures used on patients to treat prostate cancer, statistical analysis will be carried out to confirm the hypothesis that Brachtherapy treatments offer the best outcomes at the lowest cost in comparison to other treatment modalities. The first stage of the project will be to review the scope and objectives of the study with the stakeholders and finalize the methodology for this analysis. It is suggested that this analysis start initially with logistic regression, which would be used for estimating the probability of being in remission after a certain period of time following treatment. We then propose to continue with a more detailed analysis using transition models. Such models are used to analyze the data where a strong dependence is suspected between successive observations on a patient. These models distinguish themselves from survival models by allowing for transitions into and out of a set of states defined by the response variable instead of focusing on the time for a certain event to occur.

Mathematical model for electric arc welding process selection based on static and dynamic characteristics

Welding plays an important role in fabrication and assembly manufacturing. Selecting the appropriate process of electric arc welding is a task assigned to the experience of those who manufacture. The materials selection for applications is as important as the selection of the manufacturing process. The consequences of not perceiving this scope cause affectation in the performance or in the life of the element. This work proposes the study of the microstructures formed in materials affected by welding processes and the changes in their mechanical properties that contribute to the performance of the fabricated elements. It is expected to identify numerically these changes and thus formulate mathematically the influence on the expected performance. It constitutes an element of analysis for the selection of the adequate electric arc welding process.

Analyse granulométrique et teneur en matière résiduelle par technique d’analyse d’images

La proportion de déchets dans les sols contaminés a une grande influence sur leur gestion. Les méthodes standards pour déterminer ces proportions sont visuelles et subjectives. L’émergence récente des réseaux de neurones convolutifs (RNC) a révolutionné l’analyse automatique des images dans différents domaines. Ces réseaux de neurones peuvent recevoir des données complexes, comme des images, pour les classer et les interpréter. On rencontre encore très peu d’applications en géotechnique et en géoenvironnement. Dans ce projet, nous proposons de créer une base de données de photographies de sols contaminés et d’entrainer un réseau de neurones convolutifs pour prédire la taille des particules et le pourcentage de déchets dans les sols contaminés à partir de photographies. Cet outil permettra d’améliorer les méthodes de caractérisation des sols contaminés et la réhabilitation des sites contaminés.

Oco is a consumer division of Carbon Upcycling Technologies, a Canadian carbon utilization company and winner of the XFactor Award in the Carbon XPRIZE. Oco uses Carbon Upcycling’s technology to offer our partners some of the easiest to integrate material decarbonization solutions on the market. Oco offers low carbon material solutions to consumer products brands and helps them take the first steps toward reaching their ambitious, world-saving climate goals.

Oco has already partnered with 25+ companies and developed 300+ CO2-embedded materials, but Oco must apply market research to further their collaborations and development. The challenge faced by the company is a limited understanding of the plans consumer goods companies have to reach their net-zero targets. This project will help Oco address this challenge by analyzing the current market for consumer products and other companies’ net-zero carbon emission goals. Furthermore, this will help Oco strengthen its knowledge of recent innovations and possible future partnerships to grow as a company to further decarbonization.

Establishing Carbon Rights and Jurisdiction as a Key Enabling Condition to Facilitate Indigenous-led Natural Climate Solutions in Canada

Indigenous-led conservation areas require an economic heart. One approach could come through natural climate solutions (NCS) – activities which protect, restore and manage lands to maximize carbon sequestration and storage. Indigenous Peoples have been managing their lands and waters for thousands of years, and they have a wealth of knowledge to continue to steward these lands in healthy and resilient ways. However there are legal and regulatory challenges to be overcome in actualizing Indigenous-led NCS . Clearly delineated right to manage the carbon in lands is a necessary precursor to creating Indigenous-led NCS as part of thriving conservation economies in Canada. Working with the Seventh Stream of the Conservation Through Reconciliation Partnership the intern will conduct research, convene conversations and gatherings to determine action steps to achieving carbon rights.

Tracking Support and Maintaining Housing

At this placement I will be assisting on many tasks which will benefit society and specified communities. Part of my work will be tracking supports, items, or services that are needed at the location. Doing this will help other interns and volunteers in the future so they know what kind of support is needed regularly. I will also help to build and expand the relationships with other organizations and partners that will facilitate our delivery of services. Logging and tracking this information will also allow us to find gaps in the types of services offered and items needed which will allow us to build additional relationships and predict future needs. This is especially important for people who need assistance to maintain their housing.

3D Ultrasound Volume Reconstruction from Inside-Out Tracking of a 2D Probe

Small, handheld, point-of-care ultrasound devices (POCUS) have been increasingly used in recent years by non-specialists for a wide variety of diagnostic and treatment tasks. Since POCUS devices produce two-dimensional (2D) images, but anatomical structures are three-dimensional, we would often like to construct 3D volumes from a sequence of 2D US scans. We can measure the location of a 2D probe using external cameras, but this is not clinically convenient, so instead we propose to use outward-looking cameras to determine the probe’s location based on objects the camera can see from the probe’s location. We will test the accuracy of this approach in a model of a key clinical application of interest – meas-uring the hip structure of newborn infants suspected of having a congenital abnormality. The partner organization will benefit by gaining insight into how effective “inside-out” tracking might be in a selected clinical application, which might help them determine whether this approach could be used in a variety of other applications.
