Grid computing is evolving as a service based, flexible and secure resource sharing environment. Currently, with the help of Grid middleware toolkits, Grids are exposing their services through programming models and command line interfaces,...
Computational grids are some of the largest computer systems in existence today. Unfortunately they are also, in many cases, the least reliable. This research examines the use of redundancy with permutation as a method of improving reliability in...
Digital images have primarily been viewed using desktop applications. These types of programs attempt to load all of an image's graphical data into memory in order to display the image in its entirety. The method is effective for images that are...
A potential source of fine grained suspended sediments in a stream system is the
upper hillslopes of the drainage. Quantifying the sediment produced and transported to a
stream from these hillslopes is challenging because of the complex nature of...
This thesis lays the groundwork for creation of a graduate-level computer forensics course. It begins with an introduction explaining how computing has invaded modern life and explains what computer forensics is and its necessity. The thesis then...
Marconi, Guglielmo, marchese, 1874-1937; Radio broadcasting--Social aspects
This dissertation is a rhetorical analysis of Guglielmo Marconi's wireless. Texts surrounding the invention reveal intersections between technology and society and communicate information about the wireless through tropes of progress. The wireless...
Industrial management--Data processing; Supervision of employees--Data processing; Decision making--Data processing
This paper models a realistic problem involving workforce assignment and training for a large manufacturing environment. In this particular environment, the workforce is undertrained and most assignments will result in necessary training. This...
High dynamic range imaging involves imaging at a bit depth higher than the typical 8-12 bits offered by standard video equipment. We propose a method of imaging a scene at high dynamic range, 14+ bits, to detect motion correlated with changes in...
Web search engines; Automatic abstracting; Graph theory--Data processing
After a user types in a search query on a major search engine, they are presented with a number of search results. Each search result is made up of a title, brief text summary and a URL. It is then the user's job to select documents for...
This thesis proposes a network based intrusion detection approach using anomaly detection and achieving low configuration and maintenance costs. A honeypots is an emerging security tool that has several beneficial characteristics, one of which is...
In order to study the movements of autonomous mobile robots, a tool is needed to quantify those movements. A testbed is an apparatus that provides a designated space for multiple mobile robots while tracking their position in real-time. That...
Many dedicated-use computer systems sold as complete products require a turn-key design delivered to the customer. This requires a system which is stable, secure, and serviceable. Adaptability of the system to existing software applications is a...
The Kosair Children's Hospital, located in Louisville, Kentucky, is the only children's hospital in the state. Recently, the hospital's emergency department has developed concerns with patient satisfaction. Patients have experienced excessive...
A system for analysis of the traffic flow on public streets and highways through the use of Floating Car Data (FCD) relies completely on the number of simultaneously contributing vehicles, a fact that is no barrier for the phases of conception and...
Supervisory control systems--Security measures; Automatic data collection systems--Security measures; Drinking water--Security measures; Computer networks--Security measures
Supervisory control and data acquisition (SCADA) systems are used by many critical infrastructures including electric power production and distribution, water and waste water treatment, rail transportation, and gas and oil distribution. Originally...
Representing the complex data in a concise and accurate way is a special stage in data mining methodology. Redundant and noisy data affects generalization power of any classification algorithm, undermines the results of any clustering algorithm and...
The goals of this dissertation is to further the understanding of the roles of two genes identified by differential display polymerase chain reaction (ddPCR) of cat visual cortex as candidate genes to play a role in visual cortical plasticity....
Three-dimensional imaging in medicine; Diagnostic imaging; Dental care
CBCT in endodontics demonstrates anatomic features in 3D that intraoral, panoramic, and cephalometric images cannot. CBCT units reconstruct the projection data to provide interrelational images in three orthogonal planes (axial, sagittal, and...
Optimizing queries in a distributed database is quite difficult. This work proposes defining new generalized quantifiers which operate on sets rather than tuples. These quantifiers would allow for easier optimization in a horizontally distributed...
Draw A Secret password systems have recently come into vogue, primarily in the role of protecting a user’s cellular smart phone from external infiltration in lieu of a password. However, these password systems are only enabled for single touch...
