A Performance Comparison Of Hypervisors For Cloud Computing, Suganya Sridharan
A Performance Comparison Of Hypervisors For Cloud Computing, Suganya Sridharan
UNF Graduate Theses and Dissertations
The virtualization of IT infrastructure enables the consolidation and pooling of IT resources so that they can be shared over diverse applications to offset the limitation of shrinking resources and growing business needs. Virtualization provides a logical abstraction of physical computing resources and creates computing environments that are not restricted by physical configuration or implementation. Virtualization is very important for cloud computing because the delivery of services is simplified by providing a platform for optimizing complex IT resources in a scalable manner, which makes cloud computing more cost effective.
Hypervisor plays an important role in the virtualization of hardware. It …
Colordots: An Intersection Analysis Resistant Graphical Password Scheme For The Prevention Of Shoulder-Surfing Attack, Jim Littleton
Colordots: An Intersection Analysis Resistant Graphical Password Scheme For The Prevention Of Shoulder-Surfing Attack, Jim Littleton
UNF Graduate Theses and Dissertations
In an increasingly mobile world, the combination of mobile computing devices, publicly accessible Wi-Fi hotspots, and camera phones pose a significant threat to alphanumeric passwords in public environments. Graphical passwords, introduced as an alternative to alphanumerical passwords, help prevent successful shoulder-surfing attacks – covertly observing or recording a password login session, however, most cannot prevent intersection analysis on the data collected through shoulder-surfing. ColorDots is a new graphical password scheme designed to be easy to use and learn, to prevent successful shoulder-surfing attacks, and to hinder intersection analysis. A software implementation of ColorDots is tested, and the results analyzed. This …
Improving The Knowledge-Based Expert System Lifecycle, Lucien Millette
Improving The Knowledge-Based Expert System Lifecycle, Lucien Millette
UNF Graduate Theses and Dissertations
Knowledge-based expert systems are used to enhance and automate manual processes through the use of a knowledge base and modern computing power. The traditional methodology for creating knowledge-based expert systems has many commonly encountered issues that can prevent successful implementations. Complications during the knowledge acquisition phase can prevent a knowledge-based expert system from functioning properly. Furthermore, the time and resources required to maintain a knowledge-based expert system once implemented can become problematic. There are several concepts that can be integrated into a proposed methodology to improve the knowledge-based expert system lifecycle to create a more efficient process. These methods are …
