University of Alberta
Abstract: Medical robotic systems can make surgical and rehabilitative interventions more efficient, accurate, accessible, and reliable while reducing the burden on health care systems. The need for such robotic technologies stems from the current long wait times for surgeries, therapies and rehabilitation sessions. Surgical, therapeutic, rehabilitation and other medical interventions can be significantly enhanced by utilizing the advantages offered by robots as well as the real-time decision-making capabilities of machines under the direct control, shared control, or supervisory control of medical professionals (surgeons and therapists). In this seminar, Dr. Mahdi Tavakoli, Professor at the University of Alberta, presents various research projects on medical robotics applications in surgery, therapy, rehabilitation, and telemedicine. The goal is to show a range of problems faced in medical robotics research and their solutions spanning instrumentation, imaging, artificial intelligence, and real-time control.

Power Quality in Microgrids- Challenges and Solutions
Mehdi Savaghebi, Associate Professor
Faculty of Engineering, The Mads Clausen Institute, University of Southern Denmark, Zealand , Denmark
University of Alberta
Abstract: Microgrids (MGs) are deemed as one of the main building blocks of the future smart grids. It is expected that in a near future, smart grid emerges as a well-planned plug-and-play integration of MGs which interact with each other. Providing a premium power quality (PQ) for the customers is one of the main objectives in smart grids. On the other hand, the proliferation of different nonlinear and single-phase loads in electrical systems has resulted in PQ problems such as voltage harmonic and unbalance. Distributed Generators (DGs) are often connected to the utility grid or microgrid through a power-electronic interface converter. Recently, many control approaches are proposed to control the DG interface converters aiming to compensate power quality problems. In this speech, analysis, challenges and compensation of PQ problems in MGs will be addressed through several control architectures.
Main topics are:
- Overview of PQ issues in MGs
- Virtual impedance and admittance for load sharing and PQ improvement
- Secondary Control for Compensation of Voltage Unbalance and Harmonics in Microgrids
- Coordinated control of voltage-controlled and current-controlled converters for PQ improvemen

Abstract: Mobility is becoming a challenging issue in upcoming IoT applications, where it is crucial to employ mobile entities. Patients with sensors attached to their body in health monitoring application, AGVs in industrial monitoring and factory automation applications, cars with several sensing devices in vehicular applications are few examples of use cases with the need for mobile nodes. In parallel, Fog computing has revolutionized network architecture, while enabling local processing of measurements, and reducing bandwidth overhead, which results in a more reliable system and real-time support. However, mobility management is a missing framework within the mobile IoT networks with Fog computing architecture. This talk gives a brief description on some of the proposed mobility solutions, which are so-called smart-HOP, mRPL, mRPL+ and seamless handoff.

Emerging technologies bring brain-inspired computing closer to the brain
Dr. Farshad Moradi, Associate Professor
Department of Engineering,
Abstract: Understanding how the brain works is the greatest challenge scientists and engineers have been facing for decades. Recent developments and discoveries in brain-machine interfaces have renewed interest in implantable devices for interfacing the brain. Currently, there is no commercially available platform for massive brain recording at the scales beyond 1000 channels, although very recently, projects like NeuraLink, have been initiated towards this ambitious goal. Such a platform giving a clear insight of how the brain works, not only helps clinical professionals to treat many neurological disorders and other disabilities, but also opens enormous opportunities for development of brain-inspired computers especially for pattern recognition from images and videos. With the current knowledge of the brain, scientists are exploring the development of brain-inspired computing systems for specific applications such as image processing and computer vision, either using current technologies or emerging technologies, to achieve an overarching goal of orders of magnitudes better performance in comparison to the current supercomputers working based on von-Neumann computing. Within this talk, I will describe the recent advances not only on brain-computing interfaces, but also the enabling technologies for development of more dense and energy-efficient computing system mimicking the behavior of the brain. Bringing these two domains together, I will conclude how the emerging technologies can enable access to more areas of the Brain, and how we, at Aarhus University in Denmark, are working towards this ambitious goal.

Thermal and Reliability Analysis in Power Electronics
Dr. Amir Sajjad Bahman, Associate Professor
Abstract: Thermal management and reliability – besides the costs – are the most challenging issues in power electronics. Besides, simulation of power electronics systems and devices is a key to achieve design for reliability. In this lecture, after a review of the basic theory of heat transfer, and loss calculation in power electronic devices, different thermal study approaches will be discussed including thermal network calculations and finite element modeling (FEM). The lecture will address the sources of heat in a power electronic system as well as the basics and possibilities of heat exchange. Case studies will show typical applications for several industrial applications. The results are compared to thermal measurements using infra-red camera. Lifetime modeling and simulation is also an important stage in a robust and reliable design that is based on the physics-of-failure approach i.e. appropriate models is prerequisite for lifetime simulation. Moreover, the different operational and environmental stresses which are applied during operation have to be considered (mission profiles). Details on failure mechanisms and mission profiles will highlight the correlation between characteristics and reliability. The lecture will present and discuss the state-of-the-art of thermal and reliability simulation in the field of power electronics. Application of simulation tools to analyze the correlation between thermal impedance and reliability and the impact of mission profiles will conclude the lecture.
