Enhanced Bioinformatics Data Modeling Concepts And Their Use In Querying And Integration, Feng Ji

Computer Science and Engineering Dissertations - Archive

In bioinformatics research, scientists usually face the problems of modeling complex data types and integrating diverse resources. Traditional data models such as EER lack the expressing power to capture many characteristics that are common in bioinformatics data. We first propose extensions to the ER model that allow accurate representation of many of these characteristics. We then utilize these concepts in an integrative system to provide an easy-to-use interface for biologists to construct queries. Our research utilizes the enhanced conceptual modeling concepts to create a prototype mediator for querying multiple data sources. The various relationships between different biological entities are all …

High Order Weighted Compact Boundary Condition, Zhengjie Wang

Mathematics Theses - Archive

In multi-dimension flows, we expect to have problems at the boundaries when a shock hits or reflects at the boundary wall the remedy to this would be to develop weighted boundary conditions similar to the Weighted Compact Scheme for the interior nodes, by choosing candidate stencils around the boundary nodes and assigning weights to each of these stencils with the ENO reconstruction. This would avoid spurious oscillations when shocks are encountered at the boundaries. This thesis investigates higher order weighted compact boundary conditions for Weighted Compact Scheme (WCS). WCS is a combination of Essentially Non Oscillatory Scheme and Weighted Compact …

Location Privacy In Sensor Networks Against A Global Eavesdropper, Kiran K. Mehta

Computer Science and Engineering Theses - Archive

While many protocols for sensor network security provide con dentiality for the content of messages, contextual information usually remains exposed. Such contextual information can be exploited by an adversary to derive sensitive information such as the locations of monitored objects and data sinks in the eld. Attacks on these components can signi cantly undermine network applications. The existing techniques defend the leakage of location information only from an adversary who sees only local network tra c. However, a stronger adversary, the global eavesdrop- per, is realistic and can defeat all existing techniques. This paper rst formalizes the location privacy issues …

Congestion Control For Networks In Challenged Environments, Guohua Zhang

Computer Science and Engineering Dissertations - Archive

Congestion occurs when resource demands exceed the capacity of a network. The goal of congestion control is to use the network as efficiently as possible. While extensive efforts have been devoted to providing optimization based, distributed congestion control schemes for efficient bandwidth utilization and fair allocation in the Internet and wireless networks, little consideration was given to congestion control for networks in challenged environments, specifically for networks with time-varying link capacities and networks that intermittently communicate. In this dissertation, we explore optimal congestion control strategies for such networks based on optimization techniques and repeated game theory. For networks with time …

The Dynamics Of Salsa: A Structured Approach To Large-Scale Anonymity, Safwan Mahmud Khan

Computer Science and Engineering Theses - Archive

Anonymity provides a technical solution for protecting one's online privacy. Highly distributed peer-to-peer (P2P) anonymous systems should have better distribution of trust and more scalability than centralized approaches, but existing systems are vulnerable to attacks as they require nodes to have global knowledge of the system. To overcome these problems and to provide more secure, distributed organization for P2P anonymity systems, prior work proposed the Salsa system. Salsa is designed to select nodes to be used in anonymous circuits randomly from the full set of nodes, even though each node has knowledge of only a small subset of the network. …

Mutual Information Based Non-Rigid Image Registration Using Adaptive Grid Generation: Gpu Implementation And Application To Breast Mri, Mei Yi Chu

Computer Science and Engineering Dissertations - Archive

In this dissertation a new approach for non-rigid image registration using mutual information is introduced. A fast method for non-rigid registration is developed by adjusting divergence and curl of an intermediate vector field from which the deformation field is computed using finite difference method. The similarity measure mutual information is employed in the gradient-based cost minimization (or mutual information maximization) of the registration. The huge amount of data associated with MRI is handled by fully automated algorithm optimized with a multi-resolution topology preserving regridding scheme.

Semi-Empirical Studies Of Solar Supergranulation And Related Phenomena, Peter Edward Williams

Physics Dissertations - Archive

In recent years, solar observations have moved from ground-based telescopes to observatories on Earth orbiting satellites, such as SOHO. They provide us with a clear and uninterrupted view of the solar disk. One instrument upon SOHO, the Michelson Doppler Imager (MDI), has proved fruitful in providing not only important information of the solar photosphere but, in combination with helioseismic methods, a method for probing the solar interior. This dissertation discusses current investigations by myself and my collaborators into surface manifestations of convection phenomena, using Doppler velocity data from MDI and produced from computer simulations. The Doppler data reveal convection cells …

Role Of Native Bees And Natural Habitats In Eggplant (Solanum Melongena) Pollination In Kenya, Barbara Gemmill-Herren, Alfred O. Ochieng'

All Peer-Reviewed Publications

The pollination requirements of eggplant (Solanum melongena) were investigated. One variety of eggplant exhibited a significantly reduced seed set in absence of pollinators, and two varieties significantly increased seed numbers when pollen deposition was enhanced. Two solitary bee species, Xylocopa caffra and Macronomia rufipes, were identified as effective pollinators of the crop. The visitation rates of these pollinators to eggplant flowers declined significantly with distance from the wild habitat. The importance of wild plants as alternative forage source for pollinators was assessed by a survey of the flowering plants in different habitats surrounding eggplant fields. While ruderal farm weeds provide …

The Synthesis And Luminescence Properties Of Lanthanide-Based Nanoparticles For Biological Application, Mingzhen Yao

Physics Theses - Archive

Lanthanide-doped nanoparticles have great potential as a new kind of luminescent material. In this thesis, we report the synthesis of Cerium-doped LaF3 nanoparticles in dimethyl sulfoxide (DMSO) using chemical reaction at different temperatures. We found that the emission of nanoparticles in DMSO not only depends on reaction temperature but also reaction time. The emission of DMSO solution can be tuned by reaction time, from 490 nm to 650 nm. The formation of LaF3:Ce3+ nanoparticles has been identified by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The TEM results show that the average sizes of these nanoparticles are within 10 …

Cap: A Context-Aware Privacy Protection System For Location-Based Services, Aniket Pingley

Computer Science and Engineering Theses - Archive

Location Based Services (LBS) are information services that provide users with customized contents, such as the nearest restaurants/hotels/clinics, retrieved from a dedicated spatial database. They make use of technologies such as Global Positioning System (GPS), triangulation/triliteration etc. to get the geographical position of the user. Since the queries on spatial database include the user's current location, LBS may raise serious concerns on the user's location privacy. If disclosed, a user's location information may be misused in many ways by a malicious adversary who has access to the LBS server or even by the LBS provider. Therefore, our aim in this …

High-Level Constraint Support For Combinatorial Testing, Anthony C. Opara

Computer Science and Engineering Theses - Archive

Combinatorial testing constructs test cases by combining different input parameter values based on some effective combinatorial strategy. This software testing approach has displayed very promising attributes and is rapidly gaining popularity in recent years. However, existing work does not provide adequate support for constraint handling. Constraints are often specified as part of an input parameter model and they may be due to several reasons such as incompatibility between certain hardware and software components. A test generation algorithm needs to take these constraints into account during the test generation process to exclude combinations that are invalid from the domain semantics. In …

Stepping-Stone Network Attack Kit (Sneak) For Evading Timing-Based Detection Methods Under The Cloak Of Constant Rate Multimedia Streams, Jaideep D. Padhye

Computer Science and Engineering Theses - Archive

With the advent of the Internet, network-based security threats have been constantly on the rise. The source of an attack could be traced by studying the system logs and the source IP address of the attack can be used to identify and prosecute the attacker. To avoid getting traced and to mislead the forensic investigators, attackers usually compromise weaker nodes on less secure networks and use them as stepping stones to attack the victim. This technique makes it difficult for the investigators to trace the real source of attack. Hence, it is important to research the stepping stone detection techniques …
