    QoE and Importance for Multimedia Streaming

    The majority of Internet traffic nowadays is multimedia content such as on-demand video, video streaming and live video stream. Internet usage has shifted towards content-centric rather than host-centric. With such evolution, the need of quality measures has emerged. Quality of Experience (QoE) is one of the major measurements techniques used to quantify user perception of an application.

    My research is focused on Quality of Experience (QoE) of multimedia streaming over software defined networking (SDN). QoE is considered one of most important and hardest measurements as it is mostly focused on measuring the user-perceived experience and how users affect the multimedia streaming experience. QoE evaluation is a very challenging topic because of its complexity as well the presence of many interrelated influence factors, not only human but also from system and context perspective. QoE is considered a multi-dimensional construct.

    QoE is not some predefined criteria that can be generally used with all types of applications. QoE is context-oriented and defined by the domain that the application belongs to. Each application should have a set of identified QoE parameters that are important for its success.

    There are several factors that could affect QoE. Some of these factors can be identified, measured and impacts are known in advance. However, other factors cannot be predicted neither quantified as well it’s hard to forecast their impacts as it’s totally dependent on certain situations and factors. There are three main factors that influence QoE: human, system and context.

    Breaking the Nuclear Waste Taboo

    Public-friendly approach to understanding the real impacts of nuclear waste.

    Life Cycle Assessment (LCA) of the nuclear waste cycle reveals palpable values of environmental impact that both the industry and public can appreciate. While LCA has been widely applied to society's large waste processing streams (such as water, landfill and recycling), there has been little success in application to nuclear waste. This is due to a number of difficulties such as lack of data and variability of solutions. Despite the challenges, the outputs of LCA is a worthwhile inventory of the actual impacts of nuclear waste. The results may start to abridge sentiments towards nuclear waste which has long been stigmatized by society.

    Advanced Electric Technology for Nuclear Industry

    Power electronics technology and DC electrical distribution system is one of the most advanced in power distribution systems which promises a lot of features that conventional AC systems cannot achieve. These features can benefit a nuclear power plant to improve its efficiency and safety. Therefore, a DC electrical system for a nuclear power plant  is designed , and the technological and economic comparisons show some significant potential improvements. However, there are sill a lot of technological and regulatory challenges that need to be addressed.

    Investigation of the Bubble Detector Response to Radiation in Space

    The radiation environment on board spacecraft includes a complex mixture of neutrons, photons, protons, heavy ions and other charged particles. The complexity of the radiation environment within spacecraft makes accurate measurements of radiation dose very difficult to achieve. Neutron radiation exposure is believed to be responsible for approximately 30 to 50 per cent of the total equivalent dose that astronauts receive. Neutrons are particularly hard to measure accurately since they are uncharged particles that interact with matter in many complicated ways, which vary significantly with incident energy. Super-heated droplet detectors are a class of radiation detectors that generate bubbles when exposed to high linear energy transfer (LET) radiation. Measurements with a specific class of super-heated drop detectors called bubble detectors have been used to evaluate equivalent dose due to neutrons in various space missions including the Matroshka-R radiation monitoring program on the International Space Station (ISS) and other spacecraft as well as the RaDI-N program on the ISS. The number of visible bubbles within a bubble detector after a given exposure is expected to be directly proportional to the total neutron dose. However, protons and other heavy charged particles on board spacecraft are a significant component of the high LET space radiation field and they definitely contribute to the production of visible bubbles. The response of bubble detectors to heavy ion irradiation present within spacecraft is not known. Furthermore, the calibration of bubble detectors is typically established by exposing the detectors to a known Americium Beryllium (AmBe) neutron field (with energies from 0 to 11 MeV). However, the space neutron field is considerably different from the AmBe field and consequently, the calibration used does not apply to space environments.

    In order to establish a reliable model of the bubble detector response to radiation in space environments, an accurate model of the mechanism of bubble formation has to be known. Current models assume that bubbles are formed as a result of radiation interactions that is above certain minimum LET threshold. But previous experiments cited in the literature have shown that the LET threshold may be different for different ions.

    The objectives of this thesis are to investigate the response of bubble detectors to high LET radiation encountered in space environments. In particular, to establish an effective physical model of the mechanism of bubble formation in these detectors based on their physical properties and the ion track structure and determine the contribution of neutrons, protons and heavy charged particles to measurements in space.

    3MT PRESENTATION TITLE

    Welcome to the Driverless World

    The modern world is moving in a direction where more and more intelligent systems are required. These systems encompass many spheres of our lives. Recently automobile industries are looking for solutions where vehicles are intelligent enough to make decisions on their own with minimum human intervention. To accomplish this, vehicles are to be integrated with radars that can relay the desired information to the artificial mechanical systems to take the corrective actions. Thus it can be said that radars are the building blocks of these new vehicles.

    Now radars are the wireless system which are implemented using the integration of various RF modules/components. One such important component is filter. The presentation will cover a novel SIW-based filter design for automotive radar technology to be employed in the new emerging autonomous vehicle industry.

    Powering Resilient, Interconnected Transportation Infrastructures

    The current energy infrastructure is fragile and prone to failures due to a multitude of reasons. The most common reasons for disruptions are due to natural disasters, such as hurricanes, floods and ice storms, however, other concerns are becoming more mainstream, such as terrorism, cyber-attacks, geopolitical conflicts and dwindling fossil fuel reserves to name a few. In Canada, the transportation sector accounts for 30 per cent of secondary energy use, due to our heavily reliance on the movement of humans and economic goods. The objective is to design resilient, interconnected microgrids with an appropriate control architecture to support the railway infrastructure. A microgrid is a small-scale electric grid which includes distributed energy resources, energy storage systems and loads, and can operate either parallel or independently from the utility grid. When coupled with an electric transportation network, the microgrid can become useful in supporting the transportation network during regular operation, and emergency events. A grid-connected microgrid will be designed to include a photovoltaic system, wind turbine, and battery energy storage system. In addition, the microgrid will also take advantage of the recovered energy from the train when it is braking and store the energy for later use. Key performance indicators are defined and used to evaluate the resilience of the microgrid. The flow of energy between all assets is managed through a supervisory control architecture, which is designed to maximize the resilience of the overall system.
