Atomic Actions in Concurrent Systems (fault-Tolerance, Control)
The concept of an indivisible sequence of actions has been in use to design concurrent systems. An atomic action is an activity, possibly consisting of many steps performed by many processors, that appears primitive and indivisible to any activity outside the atomic action. The aim of the thesis is …

Grid-based utility middleware infrastructure for distributed services provisioning
… remains a key challenge to the reality of on-the-fly application composition using available services in an ecosystem. Current state-of-the-art service composition strategies are based on a predefined sequence of actions or workflow and are unsuitable when applied in dynamic and open …

Robust planning and scheduling using column generation
… Planning and Scheduling (APS) is the problem of autonomously planning, scheduling and executing a sequence of actions in an environment to achieve some goals. Due to the increased adoption of APS in sensitive applications, there is an increasing need for models that are robust to the …

Network optimization in adversarial environments
… tractability. However, an increasing number of real-world networked systems exhibit complex behaviors that cannot be captured by the simple stochastic models, such as networks under malicious attacks and networks with uncontrollable nodes. In this thesis, we study efficient network control …

Manipulation with diverse actions
… in which we are given a mobile robot, a set of movable objects, and a set of diverse, possibly non-prehensile manipulation actions, and the objective is to find a sequence of actions that moves each of the objects to a goal configuration. We argue that classic sampling-based techniques cannot …

More or less exact
More or Less Exact tests the fidelity of material control by hands, by machines, and by the interaction of the two. We overlap two models of exactitude within the discipline of architecture to expose a design space at their intersection. One model, underlying Western practice since modernism, is …

Reliably arranging objects : a conformant planning approach to robot manipulation
… robotics is achieving reliable results in spite of sensing and control uncertainty. In this work, we explore the conformant planning approach to reliable robot manipulation. In particular, we tackle the problem of pushing multiple planar objects simultaneously to achieve a specified arrangement …

Language Learning in Interactive Environments
… long been considered a defining characteristic of human intelligence. I am motivated by the question of how learning agents can understand and generate contextually relevant natural language in service of achieving a goal. In pursuit of this objective, I have been studying Interactive …

A general approach to temporal reasoning about action and change
Reasoning about actions and change based on common sense knowledge is one of the most important and difficult tasks in the artificial intelligence research area. A series of such tasks are identified which motivate the consideration and application of reasoning formalisms. There follows a …

Incorporating Memory and Learning Mechanisms Into Meta-RaPS
<p>Due to the rapid increase of dimensions and complexity of real life problems, it has become more difficult to find optimal solutions using only exact mathematical methods. The need to find near-optimal solutions in an acceptable amount of time is a challenge when developing more sophisticated …

Transit crimes in the Internet age: How new online criminal opportunities affect the organization of offline transit crimes
… the extent to which the Internet is exploited by offenders to carry out transit crimes and the way in which it has changed those offenders’ behaviors and the criminal processes remains under- investigated. The aim of this thesis is to understand what kind of criminal opportunities the Internet …

Towards Improving and Extending Traditional Robot Autonomy with Human Guided Machine Learning
… automated planning methods that found a viable sequence of actions, which, if executed by an agent, would result in the successful completion of the given task(s). However, many tasks that we would like robotic agents to perform involve goals that are complex, poorly-defined, or hard to specify. …

Coding and scheduling in networks for erasures and broadcast
… is concerned with the design and analysis of algorithms that address two related issues in communication networks, namely erasures and broadcast. Erasures are an appropriate model for communication channels from a network layer perspective. A class of efficient and flexible codes known as …

Scalable attack modelling in support of security information and event management
… using vulnerability assessment tools, modelling of more intricate attacks, which incorporate multiple steps on different machines, requires more advanced techniques. Attack graphs are a promising technique, however they face a number of challenges. An attack graph is an abstract description of …
