Diagnosing Security Risks in an Industrial Control System using a Novel Real-Time Device

The integration of control system workstations with wireless networks in critical infrastructure systems raises a major challenge as it now requires the ability to detect cyber security threats which could ultimately cripple the organization’s network.

Making connections improves wireless connectivity

As a PhD student in the Department of Systems and Computer Engineering at Ottawa’s Carleton University, Hassan’s research focused on the efficiency of wireless systems — finding newer and better ways to control how cellular and Wi-Fi systems allocate network resources optimally.

An emerging power: Brazilian South-South Cooperation in Mozambique and Haiti

This project considers how the rise of Brazil to global power status has changed its foreign policy direction, especially with regards to how it engages with other developing nations. In particular, this study considers how emerging powers like Brazil have dramatically increased the development assistance – what they call South-South Cooperation - they have provided to other developing countries over the previous decade. Why has assistance become such a valued foreign policy tool?

Security Investigation and Solutions to Online Advertising Fraud Problems

The market share of online advertising, also known as Internet advertising, has been increasing dramatically in recent years. On the other hand, malicious behaviors, such as click fraud, have degraded the effectiveness of online advertising. Via fraud clicks, a considerable amount of revenues have been lost to fraud conductors. For instance, based on a report published by PricewaterhouseCoopers, click fraud accounts for as much as 36% of all advertising clicks, which costs defrauded advertisers hundreds of millions of dollars annually.

Collective will and the Brazilian Left: how is a real movement built out of a crisis of praxis?

This project is intended to follow and analyse the most recent activities of groups identified to be in the Brazilian Left. Through fieldwork and theoretical analysis, the goal is to understand how the Left views itself, how collective will can be developed within these groups, and if a critical pedagogical methodology can assist in this process. The ethnographic methodology employed in this project will help to identify who the main actors are and what kind of activities have been prioritized by Left organizations.

Mahseer on the move: Exploring the post-release behaviour and movement of mahseer (Tor spp.) after catch-and-release angling using biotelemetry

Recreational fishing is a popular activity worldwide that contributes an estimated $190B USD in expenditures to the global economy each year. Contrasting the economic benefits of the activity is an array of ecological and biological impacts. Catch-and-release fishing, the act of returning a fish to water (presumably unharmed) after landing, has become an increasingly popular strategy to mitigate these impacts. Yet, different species respond differently to catch-and-release practices.

Stochastic Control in Network Coding Enabled Wireless Systems Year One

Network stochastic control is considered as a primary goal in the design of emerging wireless networks. One of the objectives in the stochastic control of wireless networks is to enable crosslayer designs to achieve stochastically optimal resource allocation in the physical and MAC layers. Different stochastic performance criteria can be considered in the optimal control of wireless networks. Delay is one of the most challenging ones and has been addressed far less in the literature.

Enabling Operator Decision-Making to Increase the Efficiency of Operator-led Collaborative Teams in Operating Centres Year Two

Operating Centre control rooms are large rooms where trained operators remotely supervise data centre equipment. Operators aim to maintain the connectivity and computer services modern society relies on. They provide services to their organizations or government or industry clients including forming and monitoring tactical teams that solve time-critical computing issues. Their daily activities include monitoring and responding to alerts, while simultaneously participating in multiple distributed teams where the role of the operator is to ensure progress towards a problem's resolution.

"Performance Optimization in 3GPP<->WiFi Traffic Steering *Renewal, previous title ""Stochastic Control in Network Coding Enabled Wireless Systems Year One"""

The mobile traffic has been increased significantly both in volume and in the variety of services in the new generation of broadband mobile networks. This made mobile operators to think about new approaches of data forwarding in wireless cellular networks. With this motivation, mobile operators have started to deploy WiFi to enhance the cellular network capacity. This is done by providing a seamless traffic steering between WiFi and cellular network.

Development and Scale Up of Precursors for Atomic Layer Deposition

Research in the Barry lab has been following two independent streams of precursor development: NHC complexes of group 11 amides for the deposition of metal films, and development of designed iminopyrrolidinates to quench low temperature thermal decomposition mechanisms. A series of novel N-heterocyclic carbene (NHC)-containing copper(I) amides have been shown to be viable ALD precursors. This family is represented by the compounds 4,5-dimethyl-1,3-diisopropyl-imidazol-2-ylidene copper hexamethyldisilazide, which was synthesized and structurally characterized.
