Scaling Security Architecture

Security has become increasingly important as cyberattacks are more prominent. Despite advances in security technologies there’s still a need for a new security architecture that is simply adaptable and scalable to different and evolving security requirements of various organizations. This project will study the latest technologies and solutions in the field of Cybersecurity that are being used to design scalable cybersecurity frameworks. We will also look at the new technologies and processes that are disrupting the existing Cybersecurity landscape. We will study the Cybersecurity solutions and infrastructure being used by different organizations and build Return on Investment (ROI) models to measure their effectiveness in scaling with an everchanging threat landscape.

Le projet vise à développer une version adaptée à une clientèle d’adultes consultant en clinique privée d’une grille permettant d’établir si l’individu présente des caractéristiques qui pourraient compromettre son suivi en psychothérapie. Une telle grille permettrait de mieux outiller les professionnels et de les aider à orienter les clients qui se présentent pour recevoir des services de psychothérapie. Elle permettrait également d’identifier et de nommer au client quels facteurs il a à travailler pour être en mesure de bien profiter d’une telle démarche.

Making the Business Case for Using Development Cost Charges for Climate Mitigation

Many communities across Canada are addressing global climate change by reducing local
greenhouse gas (GHG) emissions and are looking for innovative and cost-effective tools to
assist their climate mitigation efforts. Development cost charges (DCCs) are monies that local
governments collect from developers to recoup some of the infrastructure-related costs
resulting from new development. A DCC for climate mitigation has strong potential to be an
effective way for local governments to offset the costs of reducing emissions. This project
makes the business case for a climate mitigation development cost charge by demonstrating
its practical application using the West Clayton neighbourhood in Surrey, British Columbia as
a case study. The City of Surrey intends to use this project to generate support for expanded
authority from the province that will allow local governments to charge a climate mitigation
DCC

Detection of enumeration attacks in cloud environments using infrastructure log data

Most computer services nowadays are provided in cloud environments. Inevitably, every individual needs to use these environments when they have to use computer services. Considering cyber threats in the cloud infrastructure, security and privacy conservation of one is really challenging. Out of date techniques are no more executable in these infrastructures. However, machine learning algorithms due to capable of handling massive data, are effective on this theme. In this project, we proposed machine learning algorithms to detect threats in the cloud environment. A basic user-friendly dashboard is developed for security analysts to conveniently monitor detected threats by this system. eSentire could benefit from this project by protecting its own customers owing to having state-of-the-art security solutions.

Classification and Anomaly Detection of Network Traffic at the edge using Transfer Learning

Anomaly network traffic threat detection has been used in many companies to detect threats. Usually, it is deployed on-premises for efficiency and privacy reasons. Anomaly detection system usually consists of a machine learning algorithm that needs tons of time to train and test. Because each company may have different network setup, it is hard to build one system that suits for everyone. So, we need to customize the system for each client. Nevertheless, it is very inefficient to retrain the algorithm from zero for each company. Therefore, we hope to prove that by using transfer learning, we can move the knowledge from an existing detection system to a new network environment without retraining the whole algorithm.

A multi-cultural comparative study into the influence national level variations have on desistance from crime

The study of desistance – researching how and why people refrain from criminal behaviour – has gained increasing attention from both academics and policymakers in recent years in many countries throughout the world. Yet despite the growing strategic importance of more comprehensively understand the processes of desisting to reduce national reoffending rates, there remains a significant gap in empirical literature which comparatively explores the impact national-level practices and structural divergence has on desistance from crime. Therefore, this research project will examine key factors impacting individual’s desistance found in a variety of mono-cultural studies through a multi-cultural, comparative project of Scotland and Québec (a province of Canada). By doing so, this project will explore how national level characteristics and processes, societal institutins, cultural and religious beliefs and economic systems shape processes of desistance from crime. This will enable a more informed understanding of what national level variations support and inhibit individual’s ability to not refrain from future offending behaviour.

Water Quality and Waste-Solids Dewatering at a Zero-Exchange Recirculating Aquaculture System

To meet growing demand, the aquaculture industry is building increasingly larger land-based farms. There are few locations which can provide enough fresh water for their operation and the industry is forced to reduce its water requirements further by modifying recirculating aquaculture systems (RAS) to incorporate zero-exchange technology. Cooke Aquaculture Inc. is currently constructing a zero-exchange RAS at Johnson Lake, located in Pennfield, New Brunswick to produce salmon parrs. This facility will be the first of its kind in the Americas. This research focuses on two possible problems which may arise with the new system. The first problem is with regards to the possible accumulation of waste metabolites in the water. A water quality monitoring program will be implemented throughout the first production cycle, and any accumulations will be remediated as they begin to arise. A model to predict nitrogen and phosphorus concentrations in the waste stream based on feed loading and measured equipment efficiencies will also be developed for optimization purposes. The second problem deals with the dewatering of waste solids generated in the system. The effectiveness of a centrifuge will be evaluated, first using lab-scale tests to optimize polymer dosing, then applying the lab-scale findings to an industrial centrifuge.

Tetraquarks and Quantum Computing

We will perform a computational calculation to determine the properties of a proposed, currently unobserved type of particle called a tetraquark, within our current understanding of particle physics. This will allow experimentalists to search for such particles, and provide tests of our theory (Quantum Chromodynamics), which we currently find to be in agreement with observations. We will also investigate new techniques for performing similar calculations in future on a new type of computer, a quantum computer, which is currently in development and provides an exciting new way of performing calculations in future.

Impact of CO2 and salinity in aquaculture on physiology, growth and health of coho salmon

As of 2017 salmonid aquaculture was worth $22 billion USD per year with the UK contributing $1.4 billion USD and Canada responsible for $988 million USD. However, despite UN directives stating a need to double production by 2050, growth is hampered by negative public perception. Typically salmonid aquaculture combines land-based freshwater hatcheries with sea-pen rearing systems. While requiring lower maintenance costs the use of sea-pens increases risk of disease in farmed fish and has been linked with parasite overspill into wild populations of salmon causing serious declines in native populations. As such there is a demand to reduce the duration of the marine grow out phase, or transition entirely to land based farm systems (referred to as recirculating aquaculture systems – RAS) which largely avoid many of these problems. However, thus far development of RAS farms has been limited due to reduced growth observed in RAS compared to pens, and the scale of RAS required to maintain fish up to harvest size. Reduced growth and adverse health outcomes have largely been attributed to various issues relating to water chemistry (e.g. CO2, salinity, pH etc.).

Incorporating Statistical Analysis of the Extensive SAMPEX Dataset to Improve Space Weather Modelling

The Van Allen Radiation Belts are a very dynamic region of space, occupying the region between a few hundred to many tens of thousands of km above the Earth’s surface. Hundreds of commercial, scientific and military satellites occupy this region of space and are therefore vulnerable to the damaging effects of the highly energetic charged particles within it. Understanding, to the point of predictability via radiation belt models, the dynamics of the Van Allen belts, is essential for protecting future infrastructure, which increasingly relies on satellite-based technology. This project seeks to combine several new analysis techniques from both the UK and Canada, to shed new light on long-term spacecraft data. This will provide a platform for a deeper understanding of radiation belt dynamics over an extended period of time, improving current models and therefore increasing our capacity to predict future behaviour.

Costs of fluoroquinolone resistance in clinical E. coli: a potential explanation for similarities in resistance between the UK and Canada

Antibiotic resistance is one of the biggest challenges faced by modern medicine. Countries operating public healthcare systems need to effectively treat patients while practising responsible antibiotic stewardship. The rising prevalence of resistance means, however, that many current first-line antibiotics are becoming ineffective. In particular, resistance to the the fluoroquinolones, a broad-spectrum class of antibiotics, is on the rise globally. Curiously, the prevalence of fluoroquinolone resistance is high on a national scale, despite differences in prescribing rates between countries such as the UK and Canada. The aim of this research is to understand if the high prevalence of fluoroquinolone resistance could be due to it having relatively little negative effect on bacterial growth in the absence of fluoroquinolone use. This would mean that resistant strains can remain prevalent even if fluoroquinolone use is reduced. To accomplish this, I will look at the effect of common resistance mechanisms in clinical strains of Escherichia coli, an organism where fluoroquinolone resistance is particularly common due to its use in treating urinary tract infections.
