server performance modeling and optimization. On the other hand, popularity of Internet

has created numerous client-server or peer-to-peer applications, with most of them,

such as online payment, purchasing, trading, searching, publishing and media streaming,

being timing sensitive and/or financially critical. The scheduling policy in Internet servers …

A Scientific Workflow System For Genomic Data Analysis, Jamal Ali Musleh Alhiyafi

Wayne State University Dissertations

Scientific workflows have become increasingly popular as a new computing paradigm for scientists to design and execute complex and distributed scientific processes to enable and accelerate many scientific discoveries. Although several scientific workflow management systems (SWFMSs) have been developed, there is a great need for an integrated scientific workflow system that enables the design and execution of higher-level scientific workflows, which integrate heterogeneous scientific workflows enacted by existing SWFMSs. On one hand, science is becoming increasingly collaborative today, requiring an integrated solution that combines the features and capabilities of different SWFMSs, which are typically developed and optimized towards one single …

Detecting Phenotype-Specific Interactions Between Biological Processes From Microarray Data And Annotations, Nadeem Ahmed Ansari

Wayne State University Dissertations

The development of high throughput technologies such as DNA microarrays has enabled researchers to measure expression levels on a genomic scale. Correct and efficient biological interpretation of the voluminous data generated by these technologies, however, remains a challenging problem. A commonly used approach in interpreting the results of such high throughput experiments is to map the list of differentially expressed (DE) genes to gene ontology (GO) terms, which provides a list of biological processes, biochemical functions, and cellular locations associated with the DE genes. A previously unexplored aspect is the identifications of unusual associations between biological processes. Such associations may …

Augmented Reality Navigation Interfaces Improve Human Performance In End-Effector Controlled Telerobotics, Keshav Chintamani

Wayne State University Dissertations

On the International Space Station (ISS) and space shuttles, the National Aeronautics and Space Administration (NASA) has used robotic manipulators extensively to perform payload handling and maintenance tasks. Teleoperating robots require expert skills and optimal performance is crucial to mission completion and crew safety. Degradation in performance is observed when manual control is mediated through remote camera views, resulting in poor end-effector navigation quality and extended task completion times. This thesis explores the application of three-dimensional augmented reality (AR) interfaces specifically designed to improve human performance during end-effector controlled teleoperations. A modular telerobotic test bed was developed for this purpose …

Habitat Succession, Hardwood Encroachment And Raccoons As Limiting Factors For Lower Keys Marsh Rabbits, Paige M. Schmidt, Robert A. Mccleery, Roel R. Lopez, Nova J. Silvy, Jason A. Schmidt

United States Department of Agriculture Wildlife Services: Staff Publications

The Lower Keys marsh rabbit (LKMR, Sylvilagus palustris hefneri), a marsh rabbit subspecies endemic to the Lower Keys, Florida was protected in 1990, however, populations continue to decline despite recovery efforts. We hypothesized on-going habitat loss and fragmentation due to succession and hardwood encroachment has led to increased edge, reduced habitat quality, and increased activity by native raccoons (Procyon lotor). These factors reduce the suitability of patches in a later successional state, thus threatening LKMR recovery and metapopulation persistence. We surveyed 150 LKMR patches in 2008, tallying adult and juvenile rabbit pellets, estimating measures of habitat succession …

Theses and Dissertations

This study examined the Academic Performance Index (API) and Adequate Yearly Progress (AYP) achievement trends between 2004 and 2006 of 58 California public elementary schools after exiting state monitoring and investigated practices for sustaining consistent achievement growth. Statistical methods were used to analyze statewide achievement trends in 58 former elementary state monitored schools in California. Findings indicated that 57% of schools demonstrated positive achievement growth on API over the 2 years after they exited state monitoring; however, only 44% of the schools were able to sustain 2 years of consecutive API growth. A larger percentage (72%) of schools maintained positive …

A Study Of African American Student Retention And Persistence At Los Angeles City College In Extended Opportunity Program And Services (Eops), Kalynda Webber Mclean

Theses and Dissertations

As the community college student population becomes more diverse, the traditional student support program activities are limited in their effectiveness (Crawford, 1999). Rodriguez (1992) reports that although community colleges are often the first entry point into higher education for African American students, there does not seem to be equal success in the retention and persistence of this group. As officials in higher education seek to assess the success or failure of the community college in serving its diverse population, many questions may arise concerning the success of special programs in retaining minority students. Some researchers have wondered whether these special …

A Study Of Efficacy And Professional Development Among Alternatively-Certified Teachers In Arizona, Carlyn Ludlow

Theses and Dissertations

The purpose of this descriptive and comparative study was to investigate the self-assessed efficacy levels of alternatively-certified teachers in Arizona. More specifically, this study examined the teachers' perceived ability to influence student learning and the extent to which, if at all, their self-reported efficacy levels differed based on the following professional development experiences: attendance in an intensive preparation program prior to teaching, participation in a district-sponsored induction program, and assignment of a mentor. This quantitative non-experimental and cross-sectional study collected original data from single groups of interns who hold a 2009-2010 Arizona Teaching Intern Certificate. A total of 164 teaching …

Gender Role Expectations In The Financial Services Industry, Carla Rocha

Theses and Dissertations

In light of the recent economic crisis, much of the government/media focus on the financial services industry has focused on regulatory issues (Obama, 2009). However, many individuals who are currently employed in the industry are concerned not only with the regulatory environment, but also with the slow progression towards greater gender equality (Bennhold, 2009; The National Council for Research on Women, 2009). The purpose of this study was to compare and contrast gender role expectations of men and women directors in the financial services industry. The researcher investigated the perceived effects of social role theory as it relates to socialization …

Automated Interpretation Of The Tandem Mass Spectra Of Peptides Using Artificial Neural Networks, Timothy Patrick Manning

Theses

The manual interpretation of mass spectra is a complex and time consuming task. The problem of manually interpreting this data is further exacerbated by the large numbers of mass spectra which can potentially be produced in a single proteoniics experiment. This shows the need for high throughput approaches to the interpretation of mass spectra. Existing automated approaches are however error prone due to the complexity of the task. Accordingly, this thesis discusses and evaluates the application of neural networks to improving the sensitivity, specificity and robustness of current approaches to the automated interpretation of such mass spectral data.

Several neural …

Toxicodynamics And Biotransformation Of Azaspiracids Incorporating Liquid Chromatography-Tandem-Mass Spectrometry (Lc-Ms/Ms) Techniques., Daniel O'Driscoll

Theses

Azaspiracids (AZAs) are a family of lipophilic polyether marine biotoxins, that have caused a number of human intoxication incidents in Europe since 1995, which was the first incident reported following the consumption by consumers of intoxicated shellfish {Mytilus edulis). This class of phycotoxins has been responsible for extended closures of shellfisheries in various locations around Europe, where levels of AZAl-3 are regulated in shellfish. Since their discovery in 1995, AZAs have become the focus of extensive research, resulting in the discovery of numerous analogues. Only AZAl and AZA2 have been found in phytoplankton and all the other analogues are believed …

A Quadratic Lower Bound For Rocchio’S Similarity-Based Relevance Feedback Algorithm With A Fixed Query Updating Factor, Zhixiang Chen, Bin Fu, John P. Abraham

Computer Science Faculty Publications

Rocchio’s similarity-based relevance feedback algorithm, one of the most important query reformation methods in information retrieval, is essentially an adaptive supervised learning algorithm from examples. In practice, Rocchio’s algorithm often uses a fixed query updating factor. When this is the case, we strengthen the linear Ω(n) lower bound obtained by Chen and Zhu (Inf. Retr. 5:61–86, 2002) and prove that Rocchio’s algorithm makes Ω(k(n−k)) mistakes in searching for a collection of documents represented by a monotone disjunction of k relevant features over the n-dimensional binary vector space {0,1}n, …
