Investigation Of Routing Protocols In A Sensor Network, Ramesh Praveenkumar
Investigation Of Routing Protocols In A Sensor Network, Ramesh Praveenkumar
All ETDs from UAB
The objective of this thesis is to model the communication and computation resources of the sensor netork, develop a framework for lifetime estimation and performance evluation of the network, and explore routing schemes so as to extend the functional lifetime of both the individual nodes and the entire network. The sensor network is severly constrained by limited resources, so, energy efficiency is the most important factor in designing the network. Designing an efficient routing protocol in a sensor network is challenging due to various factors, such as limited resources, concentration of load to a limited portion of the network, and …
A Framework For Improving Tractability In Software Development, Sambit Patnaik
A Framework For Improving Tractability In Software Development, Sambit Patnaik
All ETDs from UAB
Present software development methodologies suffer from a common disadvantage that they do not allow seamlessly mapping the final implementations to the originating requirements. Most of the advances made in this area have been in the form of policy rather than processes and framework which support that kind of tractability. New software environments constituting component-based software promise to change the present picture. Web services and semantic web are upcoming technologies. Their popular use in the software industry is inevitable, dependent only upon how fast they mature into reliable technologies. Web services evolved from component software technology which is based upon the …

Design Of Randomly Placed Microphone Array, Srichandana Jasti
All ETDs from UAB
Microphone arrays can be employed in noise and vibration analysis to detect and analyze changes in noise sources. One weakness of microphone arrays is the presence of artifacts (ghost sounds not present in the true signal) caused by the array geometry. Previous researchers have attempted to move the microphones around their original array positions (moving over a small amount from the current position) to distinguish the presence of true noise sources from artifacts. While these methods have shown promise, the original authors have hypothesized that the best method would be to randomly move the microphones around their respective positions. This …

Network And Data Security, Chintan Dalwadi
All ETDs from UAB
With a growing number of users getting connected to the Internet and given their growing reliance on computers, it has become increasingly important to protect the confidential information stored locally or on the Internet. There are people who greatly under estimate the threats posed in the world of information technology and believe that their identities and information are safe, and of those people who are actually concerned about security, most are unaware of the areas where they can be targeted. It is not surprising that there are very few areas in information technology that have not been compromised. It is …
Cross Chip Probe Matching Tool: A Tool For Linking Probes From Microarrays Within And Across Species, Ruchi Ghanekar
Cross Chip Probe Matching Tool: A Tool For Linking Probes From Microarrays Within And Across Species, Ruchi Ghanekar
All ETDs from UAB
raditionally, but not exclusively, a microarray experiment is conducted on a single type of microarray. However, different labs often use different chip types, and new versions of chips may be developed. Comparing experiments can be problematic in such cases, as it is not always clear which probe sets correspond to the same gene across experiments. The goal of this research was to develop a tool that allows investigators to identify probe sets that correspond to the gene within and across species. The Cross Chip Probe Matching Tool (CCPMT) makes use of the probe sequences for all features on arrays from …
Multimodality Image Registration, Persis Prasai
Multimodality Image Registration, Persis Prasai
All ETDs from UAB
Image registration has been a major area of research in the last few decades. It is a complex problem that involves handling large data sets. The relation between the real object and the image is very intricate and encompasses the object’s shape, surface properties, position, and illumination. In this thesis, a general solution to this problem was devised that can be applied to multimodality and within-modality image registration. The approach followed here is such that various factors such as illumination do not affect the algorithm. The algorithm considers the intensity of the images as raw data for the registration. The …
