Design And Development Of A Low-Cost High Range Resolution X-Band Radar, Paul C. Cantu

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

Synthetic Aperture Radar (SAR) is one of the main tools for microwave remote sensing because of its multi-dimensional high resolution characteristics and the capability to operate in nearly all weather conditions, day and night. The University of Nebraska-Lincoln (UNL) initiated the design and development of a low-cost airborne SAR in January 2001 to support our Airborne Remote Sensing Program. The objectives of this project are separated into various evolutionary stages. This thesis will focus on the initial phase of design and construction of an X-band high range resolution radar (HRR) using basic RF /microwave and digital components. The following stages …

Optimization Model Estimates Of Trunk Muscle Forces Do Not Correlate With Emg Activity Of Females As Well As Males, Mark L. Mcmulkin, Jeffrey C. Woldstad, Richard E. Hughes

Department of Industrial and Management Systems Engineering: Faculty Publications

Biomechanical optimization models are often used to estimate muscular and intervertebral disc forces during physical exertions. The purpose of this study was to determine whether an optimization-based biomechanical model predicts torso muscular activity of males and females equally well. The Minimum Intensity Compression (MIC) model, which has been extensively applied in industrial ergonomic task analysis, was used to estimate muscle forces for 3D moments. Participants (6 M, 6 F) performed 18 isometric exertions resisting 3D L3/L4 moments while electomyographic( EMG) activity was recorded for 8 muscles. Overall, model force estimates correlated better with male EMG activity (R² = …

Effects Of Age-Related Gait Changes On The Biomechanics Of Slips And Falls, Thurman E. Lockheart, Jeffrey C. Woldstad, James L. Smith

Department of Industrial and Management Systems Engineering: Faculty Publications

A laboratory study was conducted to examine gait changes associated with aging and the effect of these changes on initiation of slips and frequency of falls utilizing newly defined biomechanical parameters of slips and falls. Twenty-eight participants from two age groups (young and old) walked around a circular track at a comfortable pace wearing a safety harness. A slippery floor surface was placed on the walking track over the force plate at random time intervals without the participants’ awareness. Synchronized kinetic and kinematic measurements were obtained on both slippery and non-slippery walking surfaces. The results indicated that older participants’ horizontal …

History Of Food Acceptance Research In The Us Army, Herbert L. Meiselman, Howard G. Schutz

US Army Research

The history of food acceptance research by the US Army in Chicago and Natick is reviewed. The review covers the staff of the two research centers, the research programs, and the significant accomplishments of the Army laboratories from the 1940s to the present. Accomplishments begin with the development of the nine-point hedonic scale, and the development of the first Food Acceptance Laboratory. Further accomplishments include studies of sensory psychophysics, food preferences, food choice and food intake. The laboratories designed methods and conducted research on the role of consumer variables in the acceptance of food products and food service systems. Recent …

Rodent Sperm Analysis In Field-Based Ecological Risk Assessment: Pilot Study At Ravenna Army Ammunition Plant, Ravenna, Ohio, Lawrence V. Tannenbaum, Matthew Bazar, Melanie S. Hawkins, Barney W. Cornaby, Elizabeth A. Ferguson, L. Chantelle Carroll, Patrick F. Ryan

US Army Research

Ecological risk assessment (ERA) guidance recommends that field-truthing efforts proceed when modeled hazard quotients (HQs) suggest that toxicological effects are occurring to site receptors. To date, no field methods have been proposed by the regulatory community that can lead to definitive determinations of acceptable or unacceptable risk for birds and mammals, the two terrestrial classes of receptors that are commonly assessed using the HQ method. This paper describes rodent sperm analysis (RSA) as a viable method to be applied in the field at sites with historical contamination. RSA is capable of detecting biological differences that bear on reproduction, a highly …

The Prevalence And Severity Of Coronary Artery Calcification On Coronary Artery Computed Tomography In Black And White Subjects, Timothy C. Lee, Patrick G. O’Malley, Irwin Feuerstein, Allen J. Taylor

US Army Research

OBJECTIVES We studied the relationship between coronary artery calcium (CAC) and race in asymptomatic, active-duty personnel in the Prospective Army Coronary Calcium (PACC) project.
BACKGROUND Valid cardiovascular risk assessments in black Americans using coronary artery computed tomography (coronary CT) require the generalizability of population-based CAC score distributions derived from primarily white patient populations.
METHODS Among 1,000 consecutive participants (mean age, 42 ± 2 years; range, 40 to 45 years), 999 participants underwent coronary CT and indicated a specific racial affiliation. This included white, non-Hispanic in 699 (69.9%) participants and black, non-Hispanic in 194 (19.4%) participants. Univariate associations between race and …

Novel Small Molecule Inhibitors Of Botulinum Neurotoxin A Metalloprotease Activity, James C. Burnett, James J. Schmidt, Robert G. Stafford, Rekha G. Panchal, Tam L. Nguyen, Ann R. Hermone, Jonathan L. Vennerstrom, Connor F. Mcgrath, Douglas J. Lane, Edward A. Sausville, Daniel W. Zaharevitz, Rick Gussio, Sina Bavari

US Army Research

Botulinum neurotoxins (BoNTs) are among the most lethal biological substances to have been weaponized and are listed as biodefense category A agents. Currently, no small molecule (non-peptidic) therapeutics exist to counter this threat; hence, identifying and developing compounds that inhibit BoNTs is a high priority. In the present study, a high-throughput assay was used to identify small molecules that inhibit the metalloprotease activity of BoNT serotype A light chain (BoNT/A LC). All inhibitors were further verified using a HPLC-based assay. Conformational analyses of these compounds, in conjunction with molecular docking studies, were used to predict structural features that contribute to …

Diet And Physical Performance, Scott J. Montain, Andrew J. Young

US Army Research

This paper provides a historical summary of military nutrition research into the role of diet for sustaining soldier physical performance. Studies of underfeeding document that physical performance is preserved during several days of underfeeding provided sufficient carbohydrate and minerals are consumed to minimize the diuresis associated with semi-starvation diets and serial intake of carbohydrate is available to support metabolism during prolonged work. The Military Recommended Dietary Allowances, AR 40-25, currently recommends that when restricted rations are required, that the ration contain at least 1100–1500 kcal, 50–70 g of protein, and a minimum of 100 g of carbohydrate on a daily …

Retrieval Of Subpixel Snow-Covered Area And Grain Size From Imaging Spectrometer Data, Thomas H. Painter, Jeff Dozier, Dar A. Roberts, Robert E. Davis, Robert O. Green

US Army Research

We describe and validate an automated model that retrieves subpixel snow-covered area and effective grain size from Airborne Visible/ Infrared Imaging Spectrometer (AVIRIS) data. The model analyzes multiple endmember spectral mixtures with a spectral library of snow, vegetation, rock, and soil. We derive snow spectral endmembers of varying grain size from a radiative transfer model; spectra for vegetation, rock, and soil were collected in the field and laboratory. For three AVIRIS images of Mammoth Mountain, California that span common snow conditions for winter through spring, we validate the estimates of snow-covered area with fine-resolution aerial photographs and validate the estimates …

A Biologic Model For Assessment Of Osseous Strain Patterns And Plating Systems In The Human Maxilla, L. Russell Alberts, Kenneth O. Phillips, Harold K. Tu, Warren W. Stinson, Andrew Friedman

US Army Research

Purpose: This study was conducted to examine a biomechanical model and to help answer fundamental questions that relate to rigid plate fixation in the maxilla. Specifically, we sought to elucidate the principal strain patterns generated in the maxilla secondary to masticatory forces as well as the amount of permanent deformational changes incurred due to these loading forces.
Materials and Methods: Cadaveric heads with the mandible removed were defleshed and placed in a 2-part testing rig to hold and position the skull for testing in a standard material testing system. Rosette strain gages were attached at predefined points on the skull, …

Newbury Park, CA: Sage) extended multilevel leadership model as a template to examine the many facets of military leadership. The military leadership literature is stratified into the systems, organizational, and direct levels of leadership with an examination of studies on the critical tasks and individual capabilities required at each level. Additionally, studies on organizational culture and effectiveness …

Protracted Protection To Plasmodium Berghei Malaria Is Linked To Functionally And Phenotypically Heterogeneous Liver Memory Cd8+ T Cells1, Dmitri Berenzon, Robert J. Schwenk, Lisa Letellier, Mimi Guebre-Xabier, Jackie Williams, Urszula Krzych

US Army Research

We previously demonstrated that protection induced by radiation-attenuated (y) Plasmodium berghei sporozoites is linked to MHC class I-restricted CD⁸⁺ T cells specific for exoerythrocytic-stage Ags, and that activated intrahepatic memory CD⁸⁺ T cells are associated with protracted protection. In this study, we further investigated intrahepatic memory CD⁸⁺ T cells to elucidate mechanisms required for their maintenance. Using phenotypic markers indicative of activation (CD44, CD45RB), migration (CD62L), and IFN-y production, we identified two subsets of intrahepatic memory CD⁸⁺ T cells: the CD44^highCD45RB^lowCD62L^lowCD122^low phenotype, representing the dominant effector …
