Earthshine : Photometry, Modeling, And Spectral Observations, Jeffrey Patrick Hickey
Earthshine : Photometry, Modeling, And Spectral Observations, Jeffrey Patrick Hickey
Theses
The Earthshine group has been making sustained observations of the Earthshine from Big Bear Solar Observatory in California since late 1998. There have also been intermittent observations from 1994-5. High and low resolution Earthshine spectral observations have also been under taken at Palomar Observatory since 1999. The group has re-invigorated and modernized a nearly forgotten way of measuring the Earth's albedo, and hence its energy balance, previously studied by Danjon (and his followers) for about twenty-five years early in the last century, using their observations of the Earthshine from France. This is an overview paper covering observations, reductions, simulations, and …

Finding Role Errors Of The Ncit Gene Hierarchy Using The Ncbi, Marc Oren
Finding Role Errors Of The Ncit Gene Hierarchy Using The Ncbi, Marc Oren
Theses
Due to the knowledge discovery process of gene information, details such as organism and chromosomal location should be known. Furthermore, the extensive biomedical research in genomics led to discovery of processes and diseases in which a gene plays a role. In the Gene hierarchy of the NCI Thesaurus (NCIT) such knowledge is represented by appropriate roles. However, upon review of the Gene hierarchy of the NCIT, many role errors are found. Realizing that such details are provided by another knowledge repository of NIH, the NCBI gene database, a methodology is presented to use NCBI to discover role errors for the …

Environmental Policy In Jordan : Analysis, Gap Identification, And Strategies For Improvement, Diana Saed
Theses
Jordan is a country with a tremendously fragile environment. It faces substantial environmental challenges due to its delicate environmental resources and its limited financial assets. These challenges are aggravated by the scarcity of available water, deterioration of the water resources, land contamination, desertification, mismanagement of land use, and air pollution. Attempting to describe the “State of the Environment” and to provide an informed analysis of the threats to the nation’s environment is a Herculean task. This analysis examines the efforts made by Jordan in regard to protection and management of the environment. This thesis provides a snapshot of the major …

A Data Gathering Toolkit For Biological Information Integration, Munira Lokhandwala
Theses
SYSTERS is a biological information integration system containing protein sequences from many protein databases such as Swiss-Prot and TrEMBL and also protein sequences from complete genomes available at Ensembl, The Arabidopsis Information Resource, SGD and GeneDB. For some protein sequences their encoding nucleotide sequences can be found in their corresponding websites. However, for some protein sequences their encoding nucleotide sequences are missing.
The goal of this thesis is to. collect all nucleotide sequences for the protein sequences in SYSTERS and store them in a common database. There are two cases. The first case is that if the nucleotide sequences can …
Separation Of Ssl Protocol Phases Across Process Boundaries, Kirthikar Anantharam
Separation Of Ssl Protocol Phases Across Process Boundaries, Kirthikar Anantharam
Theses
Secure Sockets Layer is the de-facto standard used in the industry today for secure communications through web sites. An SSL connection is established by performing a Handshake, which is followed by the Record phase. While the SSL Handshake is computationally intensive and can cause of bottlenecks on an application server, the Record phase can cause similar bottlenecks while encrypting large volumes of data.
SSL Accelerators have been used to improve the performance of SSL-based application servers. These devices are expensive, complex to configure and inflexible to customizations. By separating the SSL Handshake and the Record phases into separate software processes, …
Network Activity Arising From Optimal Diameters Of Neuronal Processes, Juliane Gansert
Network Activity Arising From Optimal Diameters Of Neuronal Processes, Juliane Gansert
Theses
Electrical coupling provides an important pathway for signal transmission between neurons. In several regions of the mammalian brain electrical synapses have been detected, and their role in the synchronization of neural networks and the generation of oscillations has been studied theoretically. Recently, it has been found that the amplitude of the postsynaptic potential is maximized for a specific diameter of the postsynaptic fiber.
In this thesis, the impact of the fiber's diameter on the success or failure of the action potential initiation and propagation is studied theoretically. Systems of two coupled neurons, as well as small networks, are investigated. The …
Comparative Analysis Of Parametric, Nonparametric And Permutation Methods For Differential Expression, Rahul Patil
Comparative Analysis Of Parametric, Nonparametric And Permutation Methods For Differential Expression, Rahul Patil
Theses
DNA microarrays permit us to study the expression of thousands of genes simultaneously. They are now used in many different contexts to compare mRNA levels between two or more samples of cells. Microarray experiments typically give us expression measurements on a large number of genes. Increasing popularity of microarray technology has resulted in a number of tests being proposed to detect differentials expression.
The purpose of study is to compare the parametric, non parametric and permutation tests when applied to microarray data for differential expression analysis. t test (parametric), Mann Whitney test (nonparametric) and Significance of analysis (permutation ) test …
The Effects Of Limited Rebuild Buffer And Track Buffers On Rebuild Time In Raid5, Chintan Shah
The Effects Of Limited Rebuild Buffer And Track Buffers On Rebuild Time In Raid5, Chintan Shah
Theses
Redundant Arrays of Independent Disks (RAID) are very popular for creating large, reliable storage systems. A RAID array consists of multiple independent disks that achieve fault tolerance by parity coding. The contents on a failed disk can be reconstructed on demand by reading and exciusive-ORing the corresponding blocks on surviving disks. Upon disk failure, the array enters rebuild mode when it begins to systematically reconstruct the data of the failed disk on a spare disk, provided one is available. The fundamental element of rebuild is the Rebuild Unit (RU).
Surviving disks engaged in rebuild, process user requests at a higher …
Dynamic Recomposition Of Documents From Distributed Data Sources, Abhishek Verma
Dynamic Recomposition Of Documents From Distributed Data Sources, Abhishek Verma
Theses
Dynamic recomposition of documents refers to the process of on-the-fly creation of documents. A document can be generated from several documents that are stored at distributed data sites. The source can be queried and results obtained in the form of XML. These XML documents can be combined after a series of transformation operations to obtain the target document. The resultant document can be stored statically or in the form of a command, which can be invoked later to recompose this document dynamically. Also, in case a change is made to a document, then only the change can be stored, instead …

Model Driven Architecture - A Tool For Enterprise Architecture : A Look At Emergency Response Systems, Ritu Lamba
Theses
Today's fast changing markets and technology drive software industry to deliver high quality enterprise software solutions. The enterprise system architecture should be designed to keep business functions separate from technological implementation to accommodate the fast changing business environment.
In this thesis we have studied the current best practices in defining enterprise architectures and Zachman's framework in particular. We have further examined the Model Driven Architecture (MDA) approach and its application to enterprise architecture definition. MDA separates the business logic from the underlying platform technology and defines a representation model based on precise semantics. Zachman's framework defines a set of views …
Classifying Rna Secondary Structures Using Support Vector Machines, Prathy Usha Sunkara
Classifying Rna Secondary Structures Using Support Vector Machines, Prathy Usha Sunkara
Theses
In contrast to DNA, RNA prevails as a single strand. As a consequence of small self-complementary regions, RNA commonly exhibits an intricate secondary structure, consisting of relatively short, double helical segments alternated with single stranded regions. The amount of sequence data available is rising rapidly day by day. One of the problems encountered on a specific molecule is finding the relevant data between the massive number of other sequences to be done by reading lists with a short description of all new entries in large databases already existing. One of the main objectives of this work is to take the …
A New Approach To Feature Extraction For Rna Structure Comparision, Girish Prakash Walawalkar
A New Approach To Feature Extraction For Rna Structure Comparision, Girish Prakash Walawalkar
Theses
In recent years, RNA structural comparison becomes a crucial problem in bioinformatics research. Generally, it is a popular approach for representing the RNA secondary structures with arc-annotation sets. Several methods can be used to compare two RNA structures, such as tree edit distance, longest arc-preserving common subsequence (LAPCS) and stem based alignment. However, these methods may be helpful only for small RNA structures because of their high time complexity. In this thesis, we propose a simplified method to compare two RNA structures in O(mn) time, where m and n are the lengths of the two RNA sequences, respectively. The method …
