Security vulnerabilities pose a serious threat to computer systems and network infrastructures. This dissertation addresses the measurement and analysis of security vulnerabilities and their impact, as well as the design of several techniques for vulnerability mitigation. The research starts with the analysis of the security vulnerabilities published in the Bugtraq list and CERT advisories. An ...

The aim of this paper is to discuss important issues for design and development of noninvasive blood glucometer. Noninvasive blood glucose monitoring could improve life quality of diabetes patients, enabling a better regulation of hyper and hypoglycemia conditions. Research to develop noninvasive glucose sensing technology is driven by the promise to provide in vivo glucose concentrations witho...

measuring individual talent is a prerequisite of talent management. in order to do so, there are methods which have been established such as intelligence tests, general and individual tests, ratings scale and the literature of educational performance. applying these methods are effective, if measurement error is low and validity is high. all current available methods are faced with issues relat...

This paper describes WeDD (Web Site Design Day), a project which brought university staff, parent helpers and school children together to design a school web site. The design process, which was modelled on participatory design, is described with reference to other work that has used a similar approach. The methods that were used to evaluate the process are described, and some general conclusion...

Government websites offer great benefits to citizens and governments. Such benefits, however, cannot be realized if websites are unusable. This study investigates usability of government websites in Uganda. Using the feature investigation method, the study evaluated four Ugandan government websites according to three perspectives. Results show that websites are partially usable in the design la...

We describe a general stochastic processes-based approach to modeling user-contributory web sites, where users create, rate and share content. These models describe aggregate measures of activity and how they arise from simple models of individual users. This approach provides a tractable method to understand user activity on the web site and how this activity depends on web site design choices...

The World Wide Web Consortium describes the Web as “the universe of network-accessible information, the embodiment of human knowledge” (W3C, 2011). This vision of the Web is contingent on the ability of users to freely access and contribute to the overall system. The freedom of the Web threatens its own future due to the possibility of users being disoriented and cognitively fatigued when tryin...

GFP and the red fluorescent protein, DsRed, have been combined to design a protease assay that allows not only for fluorescence resonance energy transfer (FRET) studies but also for dual-color crosscorrelation analysis, a single-molecule-based method that selectively probes the concomitant movement of two distinct tags. The measurement principle is based on a spectrally resolved detection of si...
