    • Ability of ADV Measurements to Detect Turbulence Differences Between Angular and Rounded Gravel Beds of Intermediate - Roughness Scale
    • Haws, Benjamin B 1980-
    • A set of laboratory experiments was carried out to distinguish flow characteristics(bed origin, shear velocity, turbulence intensity, turbulent kinetic energy) between beds of differing gravel angularity. Ten vertical profiles of velocity...


    • Construction of a Calcium Matter-Wave Interferometer
    • Erickson, Christopher Joseph 1980-
    • I describe the construction of a calcium matter-wave interferometer. The interferometer is based on a Ramsey-Borde scheme, and uses a thermal beam of atoms excited by an optical-frequency transition in calcium. In our experiment four pi/2 pulses of...


    • Decentralized Estimation Using Information Consensus Filters with a Multi-static UAV Radar Tracking System
    • Casbeer, David W 1978-
    • This dissertation lays out a multi-static radar system with mobile receivers. The transmitter is at a known location emitting a radar signal that bounces off a target. The echo is received by a team of UAVs that are capable of estimating both...


    • Experiments with GMTI Radar using Micro-Doppler
    • Dilsaver, Benjamin Walter
    • As objects move, their changing shape produces a signature that can be measured by a radar system. That signature is called the micro-Doppler signature. The micro-Doppler signature of an object is a distinguishing characteristic for certain...


    • Investigation of Particle Velocity and Drag with Spherical and Non-Spherical Particles Through a Backward Facing Step
    • Larsen, Kyle Frederick 1958-
    • Numerous practical applications exist where dispersed solid particles are transported within a turbulent accelerating or decelerating gaseous flow. The large density variation between phases creates the potential for significant differences in...


    • Motion Compensation of Interferometric Synthetic Aperture Radar
    • Duncan, David P 1978-
    • Deviations from a nominal, straight-line flight path of a synthetic aperture radar (SAR) lead to inaccurate and defocused radar images. This thesis is an investigation into the improvement of the motion compensation algorithm created for the BYU...


    • Optimizing Wireless Network Throughput: Methods and Applications
    • Zhan, Pengcheng 1980-
    • Ever since Marconi succeeded in his first demonstration on the possibility to communicate over the air overseas about a century ago, wireless communications have experienced dramatic improvements. Today's world sees the penetration of wireless...


    • Pharmacokinetics of Dexamethasone Delivered via Iontophoresis
    • Rigby, Justin Holbrook
    • Study Design: Controlled laboratory study. Objectives: To determine the time course of dexamethasone sodium phosphate (Dex-P) iontophoresis delivery to underlying tissues using microdialysis. Background: The efficacy of iontophoresis at delivering...


    • Robust Signaling, Scheduling and Authentication in the Multi-User Multiple-Input-Multiple-Output Channel
    • Shi, Yan
    • Multiple-input multiple-output (MIMO) networks are known to be able to achieve throughput performance superior to that available from single-input single-output (SISO) systems. However, when applying MIMO in multi-user networks, achieving this...


    • Scanning Laser Registration and Structural Energy Density Based Active Structural Acoustic Control
    • Manwill, Daniel Alan 1983-
    • To simplify the measurement of energy-based structural metrics, a general registration process for the scanning laser doppler vibrometer (SLDV) has been developed. Existing registration techniques, also known as pose estimation or position...


    • The Effect of Local Heating on the Concentration of Interstitial ATP in Human Skin
    • Gifford, Jayson R.
    • Skin blood flow (SKBF) demonstrates a biphasic response to innocuous, local heating. Much about the mechanism of the first phase is unknown. A type of ion channel (TRPV3) sensitive to and increasingly activated by temperatures from ~33 to ~45°C...


    • The Effect of Whole Body Vibration on Skin Blood Flow and Nitric Oxide Production
    • Johnson, Paula K.
    • Background: Vascular dysfunction due to hyperglycemia in individuals with diabetes is a factor contributing to distal symmetric polyneuropathy (DSP). Reactive oxygen species (ROS) reduce the bioavailability of nitric oxide (NO), a powerful...


    • Two-Photon Ionization of the Calcium 4S3D 1D2 Level in an Optical Dipole Trap
    • Daily, Jared Estus 1974-
    • This thesis reports an optical dipole trap for atomic calcium. The dipole trap is loaded from a magneto-optical trap (MOT) of calcium atoms cooled near the Doppler limit (~1 mK). The dipole trap is formed by a large-frame argon ion laser focused to...


    • Velocity and Temperature Characterization of the First Vacuum Stage Expansion in an Inductively Coupled Plasma - Mass Spectrometer
    • Radicic, William Neil 1973-
    • The inductively coupled plasma – mass spectrometer (ICP-MS) is the analytical instrument of choice for trace element detection and quantification. Despite the popularity of ICP-MS, significant degradation in sensitivity and precision occurs...



    • Wind/Rain Backscatter Modeling and Wind/Rain Retrieval for Scatterometer and Synthetic Aperture Radar
    • Nie, Congling 1974-
    • Using co-located space-borne satellite (TRMM PR, ESCAT on ERS 1/2) measurements, and numerical predicted wind fields (ECMWF), the sensitivity of C-band backscatter measurement to rain is evaluated. It is demonstrated that C-band radar backscatter...
