A Novel Method for Quantifying Uncertainty in the Unified Envelope of Constraint in the Passive Knee Joint
(University of Kansas, 2018-12-31)The Experimental Joint Biomechanics Research Lab at the University of Kansas created the unified envelope (UE) of constraint as a means for describing the overall laxity of the passive knee joint. The UE is currently ... -
Optimized Synthetic Aperture Radar (SAR) processing for Airborne UWB FMCW Radar
(University of Kansas, 2018-12-31)Remote Sensing of snow covered sea ice in melting Polar Regions has become crucial in estimating the results of increased global warming and to overcome the Earth’s energy imbalance. And to accurately map the snow models ... -
Aeroacoustic Analysis of a Wind Turbine with Sinusoidal Leading-Edge Blade
(University of Kansas, 2018-12-31)Wind turbines are a major source of renewable power generation in the U.S with a share of 4.7% in total electricity produced and is a clean energy source. While wind energy has its advantages, it also has room for improvement ... -
Earthquake-Resistant T-Shaped Concrete Walls with High-Strength Reinforcement
(University of Kansas, 2018-12-31)This study examined the effects of the mechanical properties of high-strength reinforcement on the seismic behavior of concrete walls. The primary variables were the yield strength f_y and the tensile-to-yield strength ... -
QuB: A Resource Aware Functional Programming Language
(University of Kansas, 2018-12-31)Modern programming languages treat resources as normal values. The static semantics of resources in such languages does not match their runtime semantics. In this thesis, we tackle the resource management problem by making ... -
EVALUATION OF THE EFFECT OF THE pH OF CONCRETE PORE SOLUTION ON THE CORROSION PERFORMANCE OF REINFORCING BARS
(University of Kansas, 2018-05-31)In this study, the effect of the pH of concrete pore solution on the corrosion resistance of reinforcement is evaluated using the rapid macrocell test (outlined in Annex A2 of ASTM A955-14). Tests are conducted on five ... -
Performance Analysis of Parametric Channel Estimation for 3D Massive MIMO/FD-MIMO OFDM Systems.
(University of Kansas, 2017-05-31)With the promise of meeting future capacity demands for mobile broadband communications, 3D massive-MIMO/Full Dimension MIMO (FD-MIMO) systems have gained much interest among the researchers in recent years. Apart from the ... -
Viscosities and Densities of Methane, Propane and Their Mixtures at Low Temperatures and High Pressures

Some Aspects of American Shortwave Radio Development
(The University of Kansas, 1929)The following pages are abstracted from a somewhat unique association with radio development. During the last twenty years the writer has been so fortunate as to be instrumental in experiments which have modified the radio ... -
An Investigation of Cardan Rotation Sequences on Lumbar Spine Lifting Kinematics
(University of Kansas, 2018-12-31)Euler angles are commonly used for kinematic descriptions due to their ability to translate to clinical contexts and the conciseness of using three rotation angles. A challenge with using Euler angles is their dependency ... -
Quantifying gait stability based on body segment coordination relationships measured with wireless sensors
(University of Kansas, 2018-12-31)SUMMARY: The purpose of this study was to investigate how the relationships between upper body (trunk) and lower body (feet) motion are affected by multiple sclerosis (MS), and how these relationships can be used to ... -
Applications of FM Noise Radar Waveforms: Spatial Modulation and Polarization Diversity
(University of Kansas, 2018-12-31)Two possible radar application spaces are explored through the exploitation of highdimensional nonrecurrent FM-noise waveforms. The first involving a simultaneous dual-polarized emission scheme that provides good separability ... -
HIGH-STRENGTH STEEL BARS IN EARTHQUAKE-RESISTANT T-SHAPED CONCRETE WALLS
(University of Kansas, 2018-12-31)The object of this study was to determine experimentally the influence of selected reinforcing steel mechanical properties on wall deformation capacity. Four large-scale T-shaped reinforced concrete wall specimens with ... -
Improved Atmospheric Density Estimation and Characterization of Uncertainty
(University of Kansas, 2018-12-31)Precise knowledge of the density in the upper atmosphere is a vital component of the orbit determination process for low Earth orbit, as inaccuracies in the estimation of atmospheric drag are the primary source of uncertainty ... -
