Linear Stochastic Systems: A White Noise Approach, Daniel Alpay, David Levanony 2010 Chapman University

Linear Stochastic Systems: A White Noise Approach, Daniel Alpay, David Levanony

Mathematics, Physics, and Computer Science Faculty Articles and Research

Using the white noise setting, in particular the Wick product, the Hermite transform, and the Kondratiev space, we present a new approach to study linear stochastic systems, where randomness is also included in the transfer function. We prove BIBO type stability theorems for these systems, both in the discrete and continuous time cases. We also consider the case of dissipative systems for both discrete and continuous time systems. We further study ℓ1-ℓ2 stability in the discrete time case, and L2-L∞ stability in the continuous time case.


Krein Systems And Canonical Systems On A Finite Interval: Accelerants With A Jump Discontinuity At The Origin And Continuous Potentials, Daniel Alpay, I. Gohberg, M. A. Kaashoek, L. Lerer, A. Sakhnovich 2010 Chapman University

Krein Systems And Canonical Systems On A Finite Interval: Accelerants With A Jump Discontinuity At The Origin And Continuous Potentials, Daniel Alpay, I. Gohberg, M. A. Kaashoek, L. Lerer, A. Sakhnovich

Mathematics, Physics, and Computer Science Faculty Articles and Research

This paper is devoted to connections between accelerants and potentials of Krein systems and of canonical systems of Dirac type, both on a finite interval. It is shown that a continuous potential is always generated by an accelerant, provided the latter is continuous with a possible jump discontinuity at the origin. Moreover, the generating accelerant is uniquely determined by the potential. The results are illustrated on pseudo-exponential potentials. The paper is a continuation of the earlier paper of the authors [1] dealing with the direct problem for Krein systems.


Comprehensive Study Of Parameters For Volumetric Modulated Arc Therapy (Vmat) Treatment Planning, Catharine Elizabeth Talbert 2010 Louisiana State University and Agricultural and Mechanical College

Comprehensive Study Of Parameters For Volumetric Modulated Arc Therapy (Vmat) Treatment Planning, Catharine Elizabeth Talbert

LSU Master's Theses

Volumetric modulated arc therapy (VMAT) is a rotational IMRT technique that uses a radiotherapy linear accelerator gantry with a dynamic MLC, variable dose rate, and variable gantry speed. These new degrees of freedom of VMAT delivery introduced complexities for treatment planning, and Pinnacle3 SmartArc treatment module was recently developed as a solution. However, it was unclear how varying each SmartArc parameter affected the resulting plan quality. The purpose of this study was to systematically examine all planning parameters and quantify the effect of varying each on the quality of a reference plan. Parameters were separated into two categories: commissioning parameters ...

This work reviews the assessment design process in depth, as relevant to classroom practice. The “assessment triangle’’ model of assessment and other design components are described. We discuss the content standards and the assigned classroom curriculum of the unit of the East Baton Rouge Algebra II course, which deals with quadratics. We offer an assessment that meets standards of the models that were reviewed.


Automatic Generation Of Music For Inducing Emotive Response, Tony R. Martinez, Kristine Monteith, Dan A. Ventura 2010 Brigham Young University

Automatic Generation Of Music For Inducing Emotive Response, Tony R. Martinez, Kristine Monteith, Dan A. Ventura

Faculty Publications

We present a system that generates original music designed to match a target emotion. It creates n-gram models, Hidden Markov Models, and other statistical distributions based on musical selections from a corpus representing a given emotion and uses these models to probabilistically generate new musical selections with similar emotional content. This system produces unique and often remarkably musical selections that tend to match a target emotion, performing this task at a level that approaches human competency for the same task.


A Comparison Of Prediction Methods Of Functional Autoregressive Time Series, Devin Didericksen 2010 Utah State University

A Comparison Of Prediction Methods Of Functional Autoregressive Time Series, Devin Didericksen

All Graduate Plan B and other Reports

Functional data analysis (FDA) is a relatively new branch of statistics that has seen a lot of expansion recently. With the advent of computer processing power and more efficient software packages we have entered the beginning stages of applying FDA methodology and techniques to data. Part of this undertaking should include an empirical assessment of the effectiveness of some of the tools of FDA, which are sound on theoretical grounds. In a small way, this project helps advance this objective.

This work begins by introducing FDA, scalar prediction techniques, and the functional autoregressive model of order one - FAR(1). Two ...


Improving Accuracy Of Large-Scale Prediction Of Forest Disease Incidence Through Bayesian Data Reconciliation, Ephraim M. Hanks 2010 Utah State University

Improving Accuracy Of Large-Scale Prediction Of Forest Disease Incidence Through Bayesian Data Reconciliation, Ephraim M. Hanks

All Graduate Plan B and other Reports

Increasing the accuracy of predictions made from ecological data typically involves replacing or replicating the data, but the cost of updating large-scale data sets can be prohibitive. Focusing resources on a small sample of locations from a large, less accurate data set can result in more reliable observations, though on a smaller scale. We present an approach for increasing the accuracy of predictions made from a large-scale eco logical data set through reconciliation with a small, highly accurate data set within a Bayesian hierarchical modeling framework. This approach is illustrated through a study of incidence of eastern spruce dwarf mistletoe ...


Simulating Power For One-Way Anova By Using Non-Normal Error Distributions, Caixia Xu 2010 Utah State University

Simulating Power For One-Way Anova By Using Non-Normal Error Distributions, Caixia Xu

All Graduate Plan B and other Reports

Usually we assume that the distribution of the additive errors in a one-way ANOVA linear model is normal. However, exceptions to this assumption about the error distribution may exist. In such cases, we might consider non-normal error distributions, but proceed with the "usual" ANOVA F-test analyses. This study focuses on simulating power for one-way ANOVA when using non-normal error distributions.


Grading Practice Influence On The Value Of An Assigned Grade, Carrie Bala 2010 Utah State University

Grading Practice Influence On The Value Of An Assigned Grade, Carrie Bala

All Graduate Plan B and other Reports

This article presents results of a study of grading practice influence on the value of an assigned grade. The value of an assigned grade, as an indication of student achievement of learning goals, was measured using the Utah Criterion-Referenced Test (CRT) in the subjects of Geometry and Algebra 2. The grading policies of six mathematics teachers at the same high school were categorized according to grading practice and their combined 587 students' scores on the Utah CRT were collected and analyzed. The findings suggest that certain grading practices , such as the use of a 1-4 scale and a criterion-referenced grading ...


Collaborative Risk Method For Information Security Management Practices: A Case Context Within Turkey, Bilge Karabacak, Sevgi Ozkan 2010 Franklin University

Collaborative Risk Method For Information Security Management Practices: A Case Context Within Turkey, Bilge Karabacak, Sevgi Ozkan

Faculty and Staff Scholarship

In this case study, a collaborative risk method for information security management has been analyzed considering the common problems encountered during the implementation of ISO standards in eight Turkish public organizations. This proposed risk method has been applied within different public organizations and it has been demonstrated to be effective and problem-free. The fundamental issue is that there is no legislation that regulates the information security liabilities of the public organizations in Turkey. The findings and lessons learned presented in this case provide useful insights for practitioners when implementing information security management projects in other international public sector organizations.


A Collaborative Process Based Risk Analysis For Information Security Management Systems, Bilge Karabacak, Sevgi Ozkan 2010 Franklin University

A Collaborative Process Based Risk Analysis For Information Security Management Systems, Bilge Karabacak, Sevgi Ozkan

Faculty and Staff Scholarship

Today, many organizations quote intent for ISO/IEC 27001:2005 certification. Also, some organizations are en route to certification or already certified. Certification process requires performing a risk analysis in the specified scope. Risk analysis is a challenging process especially when the topic is information security. Today, a number of methods and tools are available for information security risk analysis. The hard task is to use the best fit for the certification. In this work we have proposed a process based risk analysis method which is suitable for ISO/IEC 27001:2005 certifications. Our risk analysis method allows the participation ...


Comparison Of Aura Mls Water Vapor Measurements With Gfs And Nam Analyses In The Upper Troposphere–Lower Stratosphere, Le van Thien, William A. Gallus Jr., Mark A. Olsen, Nathaniel Livesey 2010 Iowa State University

Comparison Of Aura Mls Water Vapor Measurements With Gfs And Nam Analyses In The Upper Troposphere–Lower Stratosphere, Le Van Thien, William A. Gallus Jr., Mark A. Olsen, Nathaniel Livesey

Geological and Atmospheric Sciences Publications

Water vapor mixing ratios in the upper troposphere and lower stratospheremeasured by the AuraMicrowave Limb Sounder (MLS) version 2.2 instrument have been compared with Global Forecast System(GFS) analyses at five levels within the 300–100-hPa layer and North AmericanMesoscale (NAM) model analyses at six levels within the 300–50-hPa layer over the two years of 2005 and 2006 at four analysis times (e.g., 0000, 0600, 1200, and 1800UTC). Probability density functions of the vapormixing ratios suggest that both analyses are oftenmoister than Aura MLS values, but NAM model analyses agree somewhat better with Aura MLS measurements than ...


Spring And Summer Midwestern Severe Weather Reports In Supercells Compared To Other Morphologies, Jeffrey Dean Duda, William A. Gallus Jr. 2010 Iowa State University

Spring And Summer Midwestern Severe Weather Reports In Supercells Compared To Other Morphologies, Jeffrey Dean Duda, William A. Gallus Jr.

Geological and Atmospheric Sciences Publications

This study compares severe weather reports associated with the nine convective system morphologies used in a recent study by Gallus et al. to an additional morphology, supercell storms. As in that previous study, all convective systems occurring in a 10-state region covering parts of the Midwestern United States and central plains were classified according to their dominant morphology, and severe weather reports associated with each morphology were then analyzed. Unlike the previous study, which examined systems from 2002, the time period over which the climatology was performed was shifted to 2007 to allow access to radar algorithm information needed to ...


Convection-Allowing And Convection-Parameterizing Ensemble Forecasts Of A Mesoscale Convective Vortex And Associated Severe Weather Environment, Adam J. Clark, William A. Gallus Jr., Ming Xue, Fanyou Kong 2010 Iowa State University

Convection-Allowing And Convection-Parameterizing Ensemble Forecasts Of A Mesoscale Convective Vortex And Associated Severe Weather Environment, Adam J. Clark, William A. Gallus Jr., Ming Xue, Fanyou Kong

Geological and Atmospheric Sciences Publications

An analysis of a regional severe weather outbreak that was related to a mesoscale convective vortex (MCV) is performed. The MCV-spawning mesoscale convection system (MCS) formed in northwest Kansas along the southern periphery of a large cutoff 500-hPa low centered over western South Dakota. As the MCS propagated into eastern Kansas during the early morning of 1 June 2007, an MCV that became evident from multiple data sources [e.g., Weather Surveillance Radar-1988 Doppler (WSR-88D) network, visible satellite imagery, wind-profiler data, Rapid Update Cycle 1-hourly analyses] tracked through northwest Missouri and central Iowa and manifested itself as a well-defined midlevel ...


Application Of Object-Based Verification Techniques To Ensemble Precipitation Forecasts, William A. Gallus Jr. 2010 Iowa State University

Application Of Object-Based Verification Techniques To Ensemble Precipitation Forecasts, William A. Gallus Jr.

Geological and Atmospheric Sciences Publications

Both theMethod for Object-basedDiagnostic Evaluation (MODE) and contiguous rain area (CRA) objectbased verification techniques have been used to analyze precipitation forecasts from two sets of ensembles to determine if spread-skill behavior observed using traditional measures can be seen in the object parameters. One set consisted of two eight-member Weather Research and Forecasting (WRF) model ensembles: one having mixed physics and dynamics with unperturbed initial and lateral boundary conditions (Phys) and another using common physics and a dynamic core but with perturbed initial and lateral boundary conditions (IC/LBC). Traditional measures found that spread grows much faster in IC/LBC than ...


Lacustrine Sediment Record Of Multiple Quaternary Lava Dams On The Owyhee River, Southeastern Oregon, Caitlin Anne Orem 2010 Central Washington University

Lacustrine Sediment Record Of Multiple Quaternary Lava Dams On The Owyhee River, Southeastern Oregon, Caitlin Anne Orem

All Master's Theses

Multiple lava dams and correlating lakes impacted the Quaternary evolution of the Owyhee River. Sediment records from lava-dammed lakes were investigated to understand effects of the West Crater (WC) lava dam (~70 ka), the Saddle Butte 2 lava dam (~144 ka), and the Bogus Rim lava dam (~1.9 Ma). Evidence from the WC lava dam and related features indicates that dam duration consisted of five stages (1) dam and lake formation at ~70 ka; (2) dam overflow and lake sedimentation from ~70–46 ka; (3) removal of lava dam and lake termination from ~46 ka to at least 36 ...
