A Nonlinear Dynamic Approach For Evaluating Postural Control, James T. Cavanaugh, Kevin M. Guskiewicz, Nikolaos Stergiou

Journal Articles

Recent research suggests that traditional biomechanical models of postural stability do not fully characterise the nonlinear properties of postural control. In sports medicine, this limitation is manifest in the postural steadiness assessment approach, which may not be sufficient for detecting the presence of subtle physiological change after injury. The limitation is especially relevant given that return-to-play decisions are being made based on assessment results. This update first reviews the theoretical foundation and limitations of the traditional postural stability paradigm. It then offers, using the clinical example of athletes recovering from cerebral concussion, an alternative theoretical proposition for measuring changes in …

Interaction Graphs For 4R2N-P Fractional Factorial Designs, M. L. Aggarwal, S. Roy Chowdhury, Anita Bansal, Neena Mital

Journal of Modern Applied Statistical Methods

Interaction graphs have been developed for two-level and three-level fractional factorial designs under different design criteria. A catalogue is presented of all possible non-isomorphic interaction graphs for 4^r2^n-p (r=1; n=2,…, 10; p=1,…,8 and r=2; n=1,…, 7; p=1,…,7) fractional factorial designs, and nonisomorphic interaction graphs for asymmetric fractional factorial designs under the concept of combined array.

Simulation Procedure In Periodic Cancer Screening Trials, Ioana Barnicescu, Ricolindo L. Cariño

Journal of Modern Applied Statistical Methods

A general simulation procedure is described to validate model fitting algorithms for complex likelihood functions that are utilized in periodic cancer screening trials. Although screening programs have existed for a few decades, there are still many unsolved problems, such as how age or hormone affects the screening sensitivity, the sojourn time in the preclinical state, and the transition probability from diseasefree state to the preclinical state. Simulations are needed to check reliability or validity of the likelihood function combined with the associated effect functions. One bottleneck in the simulation procedure is the very time consuming calculations of the maximum likelihood …

Jmasm20: Exact Permutation Critical Values For The Kruskal-Wallis One-Way Anova, Justice I. Odiase, Sunday M. Ogbonmwan

Journal of Modern Applied Statistical Methods

The exhaustive enumeration of all the permutations of the observations in an experiment is the only possible way of truly constructing exact tests of significance. The permutation paradigm requires no distributional assumptions and works well with values that are normal, almost normal and non-normally distributed. The Kruskal-Wallis test does not require the assumptions that the samples are from normal populations and that the samples have the same standard deviation. In this article, the exact permutation distribution of the Kruskal-Wallis test statistic is generated empirically by actually obtaining all the distinct permutations of an experiment. The tables of exact critical values …

Applications Of Some Improved Estimators In Linear Regression, B. M. Golam Kibria

Journal of Modern Applied Statistical Methods

The problem of estimation of the regression coefficients under multicollinearity situation for the restricted linear model is discussed. Some improve estimators are considered, including the unrestricted ridge regression estimator (URRE), restricted ridge regression estimator (RRRE), shrinkage restricted ridge regression estimator (SRRRE), preliminary test ridge regression estimator (PTRRE), and restricted Liu estimator (RLIUE). The were compared based on the sampling variance-covariance criterion. The RRRE dominates other ridge estimators when the restriction does or does not hold. A numerical example was provided. The RRRE performed equivalently or better than the RLIUE in the sense of having smaller sampling variance.

Publications and Research

The nocturnal drainage flow of air causes significant uncertainty in ecosystem CO₂, H₂O, and energy budgets determined with the eddy covariance measurement approach. In this study, we examined the magnitude, nature, and dynamics of the nocturnal drainage flow in a subalpine forest ecosystem with complex terrain. We used an experimental approach involving four towers, each with vertical profiling of wind speed to measure the magnitude of drainage flows and dynamics in their occurrence. We developed an analytical drainage flow model, constrained with measurements of canopy structure and SF₆ diffusion, to help us interpret the tower …

An Evaluation Of The Oregon Department Of Transportation’S (Odot) Environmental Streamlining Efforts: A Focus On Cetas, Connie P. Ozawa, Jennifer Dill

Urban Studies and Planning Faculty Publications and Presentations

The Oregon Department of Transportation responded to the federal call in the late 1990s to streamline the National Environmental Policy Act (NEPA) by (1) implementing organizational and procedural changes internal to the agency, (2) funding ODOT-dedicated staff positions in state and federal resource agencies, and (3) convening regular meetings with state and federal agencies with NEPA-related regulatory responsibilities. This latter effort evolved into the CETAS (Collaborative Environmental and Transportation Agreement for Streamlining) process that includes a management and a technical team element. This document reports an assessment of the effectiveness of these efforts. Phase I of the study was designed …

Modeling Fuzzy Rules With Description Logics, Sudhir Agarwal, Pascal Hitzler

Computer Science and Engineering Faculty Publications

In real application scenarios, input data and knowledge is often vague. Likewise, it is often the case that exact reasoning over data is impossible due to complex dependencies between input data and target outputs. For practical applications, however, good approximations often suffice, and efficient calculation of an approximate answer is often preferable over complex processing which may take a long time to come up with an exact answer. Fuzzy logic supports both features by providing fuzzy membership functions and fuzzy IF-THEN rule bases. In this paper, we show how fuzzy membership functions and fuzzy rules can be modeled by means …

Isolation And Characterization Of Hydrocarbon Degrading Bacteria From Environmental Habitats In Western New York State, Katarina Malatova

Theses

Screening of hydrocarbon degrading microorganisms isolated from three habitats in Western New York State by selective enrichment technique, resulted in the collection of 20 distinct species. All strains were cultivated in liquid media with crude oil as a sole carbon and energy source. Bacterial strains capable of degrading hydrocarbons belong to the genera Serratia marcescens, Acinetobacter baumannii and Pseudomonas sp. Carbon dioxide evolution experiments were used as the major indicator of microbial degradation of oil in biometric flasks. The measurements of CO₂ evolution rates have shown to effectively evaluate the biodegradation rates by providing significant data within …

Startup/Seed Stage Investment By Venture Capital Funds (In Israel): Entrepreneurs In Residency And Executive In Residency Programs, Jimmy Schwarzkopf

Student Scholarship

What constitutes venture capital and what constitutes angel financing is a natural question. In the time period after the bubble burst in 2000 it became easy to differentiate: 1. Angel investors: usually high status individuals, former successful technology entrepreneurs who use their financial wealth, which financed birth and initial growth of ventures. 2. Venture capital (VC): independently managed, dedicated pools of capital that focus on equity-linked investments in privately held, high growth companies needing mid stage financing. Startup/seed financing were usually not acceptable VC funding phases, because of the greater risks involved. The growth in Startup/Seed Financingby VCs (almost 100% …

Rate Response Assessment From Various Granular Vrt Applicators, John P. Fulton, Scott A. Shearer, Stephen F. Higgins, Matthew J. Darr, Timothy S. Stombaugh

Biosystems and Agricultural Engineering Faculty Publications

Variable-rate technology (VRT) adds complexity to application equipment, thereby confounding the assessment of applicator performance. The intent of this investigation was to assess the rate response of various VRT granular applicators: two spinner spreaders (A and B), and two pneumatic applicators (C and D). Variable-rate (VR) tests were conducted to quantify the rate response characteristics (delay and transition times) for the applicators. A sigmoidal function was used to model the rate response for five of the six tests. Applicator A exhibited a linear response during decreasing rate changes. Results indicated that only applicator B demonstrated consistent delay and transition times, …

Fuel cell and photovoltaic are the most promising technologies for the urban residential and small commercial users. For economic and reliability purposes, it is desirable for these facilities to be interconnected with the utility grid to perform peak shaving, demand reduction, and to serve as emergency …

Bond Strength And Transfer Length Of Pre-Tensioned Bridge Girders Cast With Self-Consolidating Concrete, Amgad F. Morgan Girgis, Christopher Y. Tuan

Civil Engineering Faculty Publications

Self-consolidating concrete (SCC) is becoming increasingly popular in the precast/prestressed concrete industry in the United States. However, there have been concerns regarding the bond strength, transfer length, and development length of prestressing strands and mild steel reinforcement with SCC. Further, there are no design guidelines for using SCC. In this study, a literature survey on the bond strength of SCC was conducted. Moustafa pullout tests were performed to determine the bond strength of 0.6 in. (15.2 mm) pretensioning strands with sec. The transfer lengths of three pretensioned concrete bridge girders were measured using Demec points. Pullout tests were also performed …

Evaluation Of Cost Effective Sensor Combinations For A Vehicle Precrash Detection System, John Carlin, Charles Birdsong, Peter Schuster, William Thompson, Daniel Kawano

Mechanical Engineering

The future of vehicle safety will benefit greatly from precrash detection -the ability of a motor vehicle to predict the occurrence of an accident before it occurs. There are many different sensor technologies currently available for pre-crash detection. However no single sensor technology has demonstrated enough information gathering capability within the cost constraints of vehicle manufacturers to be used as a stand alone device. A proposed solution consists of combining information from multiple sensors in an intelligent computer algorithm to determine accurate precrash information. In this paper, a list of sensors currently available on motor vehicles and those that show …

Mining Engineering Faculty Research & Creative Works

The design and performance of a compact autonomous completely explosive pulsed power system based on two physical effects, the transverse shock wave demagnetization of Nd2Fe14B high-energy hard ferromagnets and magnetic flux compression, are presented. A transverse shock wave ferromagnetic generator (FMG) served as a seed source, and a compact helical magnetic flux compression generator (FCG) was used as a pulsed power amplifier. Results of a theoretical and experimental study demonstrated reliable operation of the proposed FMG-FCG system. The methodology for analytical calculation of seed current amplitude is developed.

A Grasp For Unitary Space-Time Codes, Adam Panagos, Kurt Louis Kosbar

Electrical and Computer Engineering Faculty Research & Creative Works

Unitary space-time codes perform well at high signal-to-noise ratios on MIMO channels even when the propagation coefficients between transmitter and receiver are unknown. One method of constructing unitary space-time constellations uses a random search to find signal constellations that minimize the maximum pairwise correlation between transmitted signals. The work presented here uses a greedy randomized adaptive search procedure (GRASP) for finding good unitary space-time code constellations. Simulation results show that, on average, this technique finds codes with better correlation properties than the random search method. This new search procedure was also used to find signal constellations with better correlation properties …

Large–Scale Field–Programmable Analog Arrays For Analog Signal Processing, Tyson S. Hall, Christopher M. Twigg, Jordan D. Gray, Paul Hasler, David V. Anderson

Faculty Works

Field-programmable analog arrays (FPAAs) providea method for rapidly prototyping analog systems. Currently available commercial and academic FPAAs are typically based on operational amplifiers (or other similar analog primitives) with only a few computational elements per chip. While their specific architectures vary, their small sizes and often restrictive interconnect designs leave current FPAAs limited in functionality and flexibility. For FPAAs to enter the realm of large-scale reconfigurable devices such as modern field-programmable gate arrays (FPGAs),new technologies must be explored to provide area-efficient accurately programmable analog circuitry that can be easily integrated into a larger digital/mixed-signal system. Recent advances in the area …

Theology Of Brotherly Love, Robert L. Marshall Jr.

Doctor of Ministry

Is it possible to have an adverse experience with Christianity and emerge being empowered by a new understanding of the gospel? Howard Thurman seems to answer that question in the affirmative. Thurman analyzes comments from Mahatma Gandhi and a barrister from "India" about Christianity under the light of the gospel. This encounter was important. It was the Genesis of Thurman's theology of brotherly love. This paper is an historical analysis of Howard Thurman's struggle to resolve the conflict between the perception that Christianity is a white man's religion and the gospel of Jesus and the disinherited. The writer will discuss …
