VHF bipolar transistor power amplifiers: measurement, modeling, and design
… of other topics related to power amplifier measurement and design are also included. A unique measurement approach which is ideally suited for use with power amplifiers is discussed. This measurement approach is a hybrid of the common S-parameter measurement technique and the "load-pull" …

Construct Validity Evidence Based on Internal Structure: Exploring and Comparing the Use of Rasch Measurement Modeling and Factor Analysis with a Measure of Student Motivation
… study examined and compared the use of Rasch measurement, common factor analysis (EFA), and confirmatory factor analysis (CFA) in establishing construct validity evidence based on internal structure with multi-item scales measuring middle and secondary students' achievement goal orientation …

Capturing Latent Abilities and Latent Capacities of Professional Golfers Using Nonlinear Mixed Effects Growth Modeling
… golfers. I used nonlinear mixed effects growth modeling (e.g., Dynamic Measurement Modeling) to measure professional golfers’ ability levels and capacities for improvement. I accomplished this using a two-stage modeling approach. First, a crossed linear mixed effects model estimated each …

Understanding Traffic Congestion Through Multiscale Analysis: Sensor Deployment, Car-Following and Universal Scaling
… noisy and limited data. Despite improvements in measurement and modeling, traffic congestion often emerges in unexpected ways, especially in dense networks operating near capacity. To better understand this concepts from statistical physics are applied to investigate whether congestion exhibits …

Influence of Prolonged Sitting and Psychosocial Stress on Lumbar Spine Kinematics, Kinetics, Discomfort, and Muscle Fatigue
… and objective measures, though the two fatigue measurement methods (based on EMG and stimulated responses) showed a good level of correspondence. Overall, this work provides a quantitative assessment of biomechanical exposures associated with seated tasks. The methods developed in this work make …

Unbiased Filtered Rayleigh Scattering Measurement Model for Aerodynamic Flows
… an attractive technique for advanced aerodynamic measurements. The appeal of FRS is that it can simultaneously quantify density, temperature, and vector velocity. Additionally, it is entirely non-intrusive to the flow since the technique leverages how laser light scatters off of molecules …
