Energy storage is viewed as one of the key ingredients to the decarbonization of the energy sector through electrification. One major challenge electricity system planners have is how one can represent and determine the optimal storage assets in long-term planning studies. In this project, the student will investigate novel ways to represent and size aggregate system-level storage technologies in deeply decarbonized electricity systems.

Tasks per student

The student will work at extending a data-driven long-term generation capacity approach currently under development in the power engineering lab. This will first involve work on manipulating large datasets of wind power generation, solar power generation and demand time series. The primary goal will be to determine sets of necessary data manipulations to determine proxy constraints that energy storage assets need to meet. An application of this method in optimizing system-level storage in a toy power system.

Haptic effects are increasingly used in consumer products, whether to deliver notifications of incoming messages, communicate information to deaf-blind individuals through their hands, or enrich videogame experiences. To produce these effects, various actuation technologies have been developed, including eccentric rotating mass, linear resonant actuators, and piezoelectric membranes, among others. Despite extensive use of these devices in consumer technologies, there has been surprisingly little in the way of investigation and comparison of their power consumption, and how power relates to the perceived intensity of the stimuli they provide. Complicating matters, such perception is dependent on frequency of the stimuli, the body location where the stimuli are delivered, and the size of the contact area. This project aims to overcome this limitation in current domain knowledge.

Tasks per student

Description

Treating patients with schizophrenia for auditory hallucinations has traditionally required multiple trials of antipsychotic medications with approximately one in three patients being resistant to antipsychotic therapies. An alternative called Avatar Therapy has been developed and shown to effectively reduce the distress and helplessness associated with auditory hallucinations. While Avatar Therapy shows great promise, there are many open questions as to the requirements for optimal delivery of this treatment. Similarly, many potential enhancements to how avatars are rendered to the patient remain to be tested. Exploration of these questions and enhancements requires development of a mixed reality platform that offers to the therapist the ability to easily adjust various parameters of the avatar(s). We will iteratively design, implement, and test such a platform, and then apply the knowledge gained to an augmented reality version of the platform suitable for use outside of the therapist's office. The resulting intelligent medical device will offer the possibility of providing therapeutic benefits to patients in their day-to-day activities.

This project aims to leverage the benefits of head-worn, panoramic imaging systems to provide navigation assistance for the visually impaired community, 1) safely guiding users during intersection crossing to avoid veering, which can be dangerous and stressful, and 2) helping them navigate the last few meters to doorways they wish to enter. Our proposed approach combines a machine learning strategy leveraging existing image datasets, possibly augmented by crowdsourcing, and iterative design of the feedback mechanisms. This is informed by our lab's experience with sensor-based intersection-crossing assistance systems, and in developing the Autour app, which provides a real-time description of street intersections, public transport data, and points of interest in the user's vicinity. Students should have experience in machine learning, mobile software development, and interest in assistive technologies.

Our lab works on the design of wearable haptic devices that can be attached to the body or inserted into regular clothing, capable of sensing human input and delivering richly expressive output to the wearer. We are particularly interested in applications to rehabilitation therapy, sports training, information communication, virtual reality, and mobile gaming. Learning a new motor skill typically requires repeated physical training, cognitive training, and retention. This project investigates the use of haptic feedback to improve learning of new dance steps, as a template example of other coordinated motor skills. For this activity, it is critical to have a precise idea of rhythm, spatial movement, and body posture during the performance. Often these factors emerge while practicing movements intermittently. However, in the process of traditional dance learning in a classroom, it is difficult for novice dancers to follow the specifics of rhythm, spatial movement and body posture, while in sync with the instructor, at a defined pace. Can these problems be reduced using vibrational feedback delivered through haptic footwear?

To accurately and efficiently model the electromagnetic fields within sophisticated microstructures of modern engineering systems and devices, high performance computing (HPC) methods, such as parallel and distributed simulations on emerging multicore/manycore platforms, are deemed promising for overcoming current computational bottlenecks. While robust and reliable 3-D automatic mesh generation procedures and solution strategies for electromagnetics are emerging, major computational challenges still remain for effective parallel and distributed 3-D adaptive finite element methods (AFEMs). Uniting AFEMs and HPC methods to achieve high gains in efficiency makes it possible to solve previously intractable problems; however, effective implementation of such techniques is still not well understood. AFEMs for parallel/distributed computing introduce complications that do not arise with simpler solution strategies. For example, adaptive algorithms utilize unstructured meshes that make the task of balancing processor computational load more difficult than with uniform structures.

Tasks per student

The students in this project will research and develop efficient parallel and distributed adaptive algorithms for unstructured meshes that use complex data structures for implementing dynamic load balancing strategies for HPC environments such as multicore/manycore architectures. The students’ role will include involvement in all aspects of the engineering research process for this project including actual implementation of algorithms as executable code.

The polymerase chain reaction (PCR) is widely used to amplify and identify DNA samples. Most commercial PCR systems require over an hour to produce a result, but we have recently demonstrated a new approach that uses laser heating of gold nanoparticles to drive the reaction. This has allowed us to produce test results in under five minutes and opens the technique up to point-of-care applications. In addition we have demonstrated a new technique to optically monitor the amplification of DNA during the reaction by measuring UV light transmittance. Specifically we measure the decrease in 260 nm optical absorption as DNA bases (deoxyribose nucleoside triphospate molecules (dNTPs)) are converted to double stranded DNA. By avoiding the use of fluorescent molecules this greatly simplifies the process. The goal of this SURE project is to develop a lock-in detection technique for UV monitoring in order to further improve sensitivity. Some of the research will be undertaken at the Lady Davis Research Institute of the Jewish General Hospital.

Tasks per student

Student 1: Adapt UV LED driver to deliver sinusoidally modulated current to LED and measure modulated signal Student 2: Insert lock-in detector into system and measure the filtered signal Both students: Develop complete system for modulation and detection, and use to measure different concentrations of dNTP molecules based on UV transmittance.

Optical microcavities are very high quality factor optical resonators which can be very sensitive to changes in their surrounding environment. By functionalising them with a suitable surface chemistry they can be used as sensors to detector specific biological or chemical molecules. Current microcavity sensors need either tunable lasers or optical spectrum analysers to operate but we are developing an approach which avoids the need for these for these by measuring the response of the resonator in the time domain rather than the frequency domain. In this approach, we modulate the optical signal at RF frequencies and then use RF detection methods to measure the attachment of the target molecules to the sensor. In this project the students will work on the design of a technique to obtain multiple measurements from a single light source that interrogates multiple resonators. The project will consist of numerical modeling and experimental validation.

Tasks per student

Student 1: Develop a numerical model of RF modulation and detection scheme, using either MATLAB or a dedicated RF modeling tool Student 2: Work alongside a graduate student to implement RF modulation and detection and compare with modeling results

For power-efficient operation, RF Power Amplifiers (PA) should operate near the saturation region, but this creates non-linear behaviors and distortions in amplified complex signals. Typical approach to balance power efficiency and performance degradation is to use PA linearizers. Non-linear power amplifier with memory is challenging to linearize using conventional models and techniques. In this project we will investigate, develop, simulate and test Deep Neural Network (DNN)-based algorithms to linearize typical power amplifiers with memory.

The limited Software Quality Assurance (SQA) resources of software organizations must focus on software modules that are likely to be defective in the future. To that end, defect prediction models are trained using historical data to identify defect-prone software modules (e.g., methods or files). After being trained using data from historical releases, defect prediction models can be used to prioritize SQA effort according the predicted defect proneness of the modules of a future release. The techniques and studies in the defect prediction literature tend to focus on source code files when making predictions. However, defects may arise in other software artifacts as well. For example, a bug in a build system file can cause software releases to be incorrectly assembled, leading to, e.g., application crashes. In this project, we will explore how defect prediction can be adapted to the context of predicting defect-prone areas of "secondary" software artifacts (e.g., build systems, test code, infrastructure scripts).

Tasks per student

The successful applicant will be expected to: - Use a high-level scripting language (e.g., Python, Ruby) to automate the collection of defect data from historical software archives like version control (e.g., Git) and issue trackers (e.g., JIRA) - Clean the data using best practices for machine learning/statistical analysis - Use machine learning and statistical techniques to analyze the data (e.g., R, Python's Scikit Learn)

Prof. Arbel is part of an interdisciplinary collaborative research network, comprised of a set of researchers from around the world, including neurologists and experts in MS, biostatisticians, medical imaging specialists, and members of the pharmaceutical industry. The team recently received a Collaborative Network Award by the International Progressive MS Alliance (IPMSA). The objectives of the grant include: (1) the federation of the first large Magnetic Resonance Image (MRI) progressive MS dataset (~40,000 patients over time) from hospitals around world and from almost all large phase 3 clinical trials for progressive MS and (2) the development of new Magnetic Resonance Imaging (MRI) markers for predicting Multiple Sclerosis disability progression for use in clinical trials. Professor Arbel’s team is currently developing new machine learning techniques to automatically discover (MRI) markers for disability prediction in progressive MS and as an outcome measure in early phase trials to facilitate drug discovery. Specifically, her team has begun to develop new deep learning frameworks that are completely data-driven, in which latent image features are identified using large amounts of imaging data. Supervised learning will result in the identification of features predictive of future clinical progression.

Mbed OS is an embedded operating created by arm for Internet of Things. It is a Real-time Operating System (RTOS) that works in highly memory constrained ARM Cortex-M micro-controller based boards. In this project, you will port the C side of the JAMScript language runtime to this operating system. Unlike a full fledged OS Linux, the Mbed OS is highly feature restricted. As a result, you need to fundamentally redesign some of the components of the JAMScript runtime to get it running in Mbed OS. Although the Mbed OS is supporting many major features you can find in a normal OS, we need to revise a lot of the code base to port the C side of JAMScript over to Mbed OS. Some third party supplied components have to be replaced or done away with. You need to undertake this project if you are really passionate about embedded operating systems and would like really learn a state-of-the-art embedded OS by mapping a complex application.

This project will extend the JAMScript runtime to support real-time audio processing tasks. There are several parts to the project. First is hooking up audio capture and processing into JAMScript programs. JAMScript is naturally a distributed language. So, we can capture with multiple sensors at the same time. There could be coordinated capture problem to gather audio signals at the same time across the different sensors. This is to capture spatial sound. We would look at the problem of specifically triggering sound capture and processing at precise time intervals. There are interesting scheduling and synchronization problems here. Because this is a summer research project, you will not be expected to solve them comprehensively, but you can relate the problems to audio processing and develop the issues that emerge from audio processing side. Second is extending the event processing mechanisms in the JAMScript runtime. This work builds on the task scheduler that is already in JAMScript and is being improved in ongoing work. As part of the extensions, we will develop mechanisms to wait for certain type of events. Third is to use the interface to capture and play audio using a single device or many devices. In the many device, case we need to investigate the synchronization in capture and playback. The fourth is benchmarking the interface and study the performance bottlenecks in the capture/playback architecture.

The 91ÉçÇø fluids laboratory is developing a multi-fan wind tunnel facility for testing unsteady aerodynamic effects on drones and other types of aircraft. To study the unsteady aerodynamics effects, the multi-fan (81 fans in total) wind tunnel facility requires a proper signal generator to vary the RPM of each fan independently. Preliminary prototyping of a signal generator to drive these 81 fans has been done using simple Arduino microcontrollers. This project aims at developing, building and testing a more robust controller that can generate 81 independent PWM signals with variable duty cycles.

Tasks per student

1) Design and fabricate a working PWM signal generator capable of generating and varying at least 81 individual outputs. 2) Help troubleshoot and optimize this device and implement desired fluctuating outputs. 3) Aid in developing a template/interface to create future signal outputs.
