Title
Algorithmic Problems in Access Control
Abstract
Access control is used to provide regulated access to resources by principals. It is one of the most important and foundational areas of research in information security. Role-Based Access Control (RBAC) is one of the most popular and widely-used access control models. In particular, it has been argued that RBAC is ideally suited for enterprise settings. In this dissertation, we address two problems in the context of RBAC.

Title
Phase-shifted Fiber Bragg Grating Based Humidity Sensor
Abstract
In recent years, fiber Bragg grating sensors have been widely used because of their unique advantages, such as its multiplexing capability, remote monitoring capability, small size and immunity to electromagnetic. However, several challenges still need to be considered, one of which is the resolution and accuracy of measurements. In this thesis, a humidity fiber optic sensor based on phase-shifted (PS) fiber Bragg gratings (FBG) is demonstrated.

Title
Nonlinear Periodic Adaptive Control for Linear Time-Varying Plants
Abstract
In adaptive control the goal is to deal with systems that have unknown and/or time varying parameters. Adaptive control techniques have been developed since 1950's and many results were proven in the cases when the time-variations were slow. However the results pertaining to systems with fast time-variations are still limited, in particular when it comes to plants with unstable zero dynamics.

Title
Generating Precise Dependencies for Large Software
Abstract
Dependencies between program elements can reflect the architecture, design, and implementation of a software project. According a industry report [23], intra- and inter-module dependencies can be a significant source of latent threats to software maintainability in long-term software development, especially when the software has millions of lines of code.

A framework to simulate and improve Terahertz Quantum Well Photodetectors
Abstract
A wide range of applications have been recognized for terahertz radiations. In fact, medical imaging, homeland security screening, very high-speed wireless telecommunications systems and even drug and gas detection are boosting the development of terahertz emitters and receivers.
