Protein Secondary Structure Prediction Using Parallelized Rule Induction From Coverings, Leong Lee, Cyriac Kandoth, Jennifer Leopold, Ronald L. Frank Dec 2009

Protein Secondary Structure Prediction Using Parallelized Rule Induction From Coverings, Leong Lee, Cyriac Kandoth, Jennifer Leopold, Ronald L. Frank

Computer Science Faculty Research & Creative Works

Protein 3D structure prediction has always been an important research area in bioinformatics. In particular, the prediction of secondary structure has been a well-studied research topic. Despite the recent breakthrough of combining multiple sequence alignment information and artificial intelligence algorithms to predict protein secondary structure, the Q3 accuracy of various computational prediction algorithms rarely has exceeded 75%. In a previous paper [1], this research team presented a rule-based method called RT-RICO (Relaxed Threshold Rule Induction from Coverings) to predict protein secondary structure. The average Q3 accuracy on the sample datasets using RT-RICO was 80.3%, an improvement over comparable computational methods. …


Grating Lobe Reduction In Aperiodic Linear Arrays Of Physically Large Antennas, William C. Barott, Paul G. Steffes Dec 2009

Grating Lobe Reduction In Aperiodic Linear Arrays Of Physically Large Antennas, William C. Barott, Paul G. Steffes

Publications

We present performance bounds obtained from the optimization of the sidelobe levels of aperiodic linear arrays. The antennas comprising these arrays are large compared to the distance between neighboring antennas, a case not addressed in previously published work. This optimization is performed in pattern-space and is applicable over a wide range of scan angles. We show that grating lobes can be suppressed even when the elemental antennas are several wavelengths in size, provided that the ratio of the antenna size to the average spacing between the antenna center-points does not exceed 80%.


Neon Allegiance, Jason Paul Olsen Dec 2009

Neon Allegiance, Jason Paul Olsen

Dissertations

This collection of thirty-one poems is built around my personal search for place, the idea of "home," and how it is relationship more than mere geography that defines the places one encounters in a life. In these poems, that idea of "home" ties back to intimate relationships with family and friends, but also with relationships involving culture—both historical and popular—as a whole.

The collection itself is a pastiche of strategies and stylizations, united by a defined and consistent voice. The geographic locations vary—from Las Vegas (where the largest number of poems and energy are focused) to stops in points across …


Electrical Switching Properties Of Ternary And Layered Chalcogenide Phase-Change Memory Devices, Martin Jared Barclay Dec 2009

Electrical Switching Properties Of Ternary And Layered Chalcogenide Phase-Change Memory Devices, Martin Jared Barclay

Boise State University Theses and Dissertations

Due to the increasing demand for products which use Non-Volatile Memory (NVM) and the near realization of the scaling limits of Flash [1, 2], a large research effort is underway. This effort is to develop new forms of NVM capable of replacing Flash [3]. At the forefront of this research is Phase-Change Random Access Memory (PCRAM). Chalcogenide based PCRAM is one of the most promising non-volatile memories for the next generation of portable electronics, due to its excellent scalability, large sensing margin, fast switching speed, and possible multi-bit per cell operation [3]. It is desirable for a phase-change random access …


Cross Sections Used To Elucidate Differences In Wavelet Transforms Of Ground Force Reactions, Wesley John Orme Dec 2009

Cross Sections Used To Elucidate Differences In Wavelet Transforms Of Ground Force Reactions, Wesley John Orme

Boise State University Theses and Dissertations

A study done for the Centers for Disease Control (CDC) found that over 50% of sports related injuries are to the lower extremities [1] with additional studies indicating that females, adolescent through collegiate, have a higher rate of lower extremity sports related injuries than males [2-4]. Conditions surrounding non-contact injuries can be analyzed using ground reaction force (GRF) data from force plates during unanticipated single leg drops, however, the expected gender differences in GRF may not be apparent when viewing data independently in the time or frequency domains.

Graphing the results of a wavelet transform, currently used by scientific, medical, …


A Parallel Computing Test Bed For Performing An Unsupervised Fluoroscopic Analysis Of Knee Joint Kinematics, Renu Ramanatha Dec 2009

A Parallel Computing Test Bed For Performing An Unsupervised Fluoroscopic Analysis Of Knee Joint Kinematics, Renu Ramanatha

Boise State University Theses and Dissertations

Fluoroscopic analysis of knee joint kinematics involves accurately determining the position and orientation of bones in the knee joint. This data can be derived using the static 3-D CT scan images and 2-D video fluoroscopy images together. This involves generating hypothetical digitally reconstructed radiographs (DRR) from the CT scan image with known position and orientation and comparing them to the original fluoroscopic frame. This represents a search problem in which, among all the DRRs possible from a CT image, the image that most closely matches the target fluoroscopy frame of the knee joint has to be found.

Each image in …


The Root Causes Of Errant Ordered Radiology Exams, Benjamin Duman Dec 2009

The Root Causes Of Errant Ordered Radiology Exams, Benjamin Duman

Boise State University Theses and Dissertations

The purpose of this research was to determine why there was a high number of errant radiology orders from requesting physicians at ATA Hospital. As the researcher, I wanted to clearly define errant orders, determine the root causes of errant orders, and further, make recommendations that would help diminish current as well as future order errors. This study answers three research questions: RQ1. Exactly what are the performance problems associated with errant orders within ATA Hospital’s radiology department that warrant further research? RQ2. What causes the increase in errant radiological orders at ATA Hospital? And, RQ3. What types of performance …


Synthesis And Characterization Of Silicon-Silicon Carbide Composites From Rice Husk Ash Via Self-Propagating High Temperature Synthesis, S Niyomwas Dec 2009

Synthesis And Characterization Of Silicon-Silicon Carbide Composites From Rice Husk Ash Via Self-Propagating High Temperature Synthesis, S Niyomwas

Journal of Metals, Materials and Minerals

Silicon-Silicon Carbide (Si-SiC) composites were synthesized by self-propagating high temperature synthesis (SHS) from a powder mixture of rice husk ash (RHA)-C-Mg. The reaction was carried out in a SHS reactor under static argon gas at a pressure of 0.5 MPa. The standard Gibbs energy minimization method was used to calculate the equilibrium composition of the reacting species. The comparison of silica from RHA and commercial sources in the precursor mixture on the Si-SiC conversion has investigated using X-ray diffraction and scanning electron microscope technique. The as-synthesized products of Si-SiC-MgO powders were leached with 0.1M HCl acid solution to obtain the …

Preparation And Characterization Of Silicon From Rice Hulls, E Swatsitang, M Krochai

Journal of Metals, Materials and Minerals

High purity silica can be prepared by reflux raw rice hulls in 1 N HCl for 45 minutes first, then pyrolyzed at 650°C for 3 hours in O2 atmosphere. The obtained white ash was examined by XRD showing a broad peak of amorphous silica at 2 theta = 22 degree. Silicon can be prepared by metallothermal reduction of pure silica at 650°C in Ar atmosphere for 1-3 hours, using magnesium (99% purity) as a reducing agent. High purity silicon (99.98 %) can be obtained by subsequently washing the as-reduced silica with HCl: H2O and HF: H2O solutions. The results from …


Utilization Of Rice Husk To Synthesize High-Performance Phosphors, L Xiong, K Saito, S Wada, E H. Sekiya Dec 2009

Utilization Of Rice Husk To Synthesize High-Performance Phosphors, L Xiong, K Saito, S Wada, E H. Sekiya

Journal of Metals, Materials and Minerals

Rice husk (RH) has high C and Si contents, so it can be used not only as a fuel candidate, but also as a low-cost Si source for synthesizing high-performance products. In the present work, we proposed a low-cost route to synthesize high-performance silicate phosphors with RH. RH was burned either as received or as pretreated by HCl washing. The resulting ashes were, respectively, utilized to react with other raw materials at high temperatures to form silicate phosphors. The high-temperature solid-state reaction process was optimized by varying either the temperature or the holding time. The crystallographic and fluorescent properties of …
