1. Susarapu, Santa Ram. ALIGNING SECURITY AND USABILITY OBJECTIVES FOR COMPUTER BASED INFORMATION SYSTEMS.

Degree: PhD, Information Systems, 2012, Virginia Commonwealth University

With extensive use of information systems in day-to-day business operations, many organizations are facing challenges to develop robust computer-based information systems that are secure and widely used by the user community. In order to develop information systems that are secure and useful, understanding what stakeholders consider important and value about the security and usability is critical. Security refers to confidentiality, integrity and availability and usability refers to efficiency, effectiveness and user satisfaction. Using Value Focused Thinking approach, this research first proposes the usability objectives based on the values of system developers and users. Using the security objectives proposed by Dhillon & Torkzadeh (2006) and the usability objectives, this research proposes hierarchies with the overall/over-arching goals of security (confidentiality, integrity, availability) and/or usability (efficiency, effectiveness and satisfaction). This research also analyzes a case of computer hacking and identifies which of the security and usability objectives that have not been met in that case study. The research contributions which include the usability objectives and security and usability hierarchies can be useful for theoretical as well as practical purposes. Advisors/Committee Members: Gurpreet Dhillon.

2. Hellström, Pär. Efficient algorithms for eigenvalue problems.

Degree: 2001, Luleå University of Technology

In computational science symmetric eigenvalue problems are central and the need for fast and accurate algorithms are high. When solving a symmetric eigenvalue problem the easiest way is to first transform the full matrix into a tridiagonal problem and then solve it. In this thesis we studie two algoritms for the symmetric tridiagonal eginvalue problem, Cuppen's Divide and Conquer and Dhillon's O(n²). These two algorithms show better performance than the classical Bisection followed by Inverse Iteration. Issues about implementation both serial and parallell are discussed.
