Quantifying the Reliability of Performance Time and User Perceptions Obtained from Passive Exoskeleton Evaluations
… due in part to insufficient information on the reliability of EXO evaluation measures. The purpose of this thesis was to quantify the reliability of common EXO evaluation measures, using both traditional approaches a more advanced statistical approach (i.e., Generalizability Theory), while also …

INVESTIGATING MODEL SELECTION AND PARAMETER RECOVERY OF THE LATENT VARIABLE AUTOREGRESIVE LATENT TRAJECTORY (LV-ALT) MODEL FOR REPEATED MEASURES DATA: A MONTE CARLO SIMULATION STUDY
… of true model parameters, sample size, measurement reliability, and missing data. The performance of the LV-ALT model for model selection is mixed. Under most manipulated conditions, the best-fitting of nine candidate models was different than the generating model, and the cost of model …

An electronically steered, wearable transcranial doppler ultrasound system
… including restrictive system form factors, measurement reliability concerns, and the need for a highly-skilled operator. The goal of this work is to reduce the effects of such limitations through the development of a highly-compact, wearable TCD ultrasound system for autonomous CBFV …

Dynamic Characterization of Wide Bandgap Devices for Power Electronic System Integration
… understanding, posing critical concerns for reliability and performance degradation. Therefore, this dissertation presents novel characterization methods, measurement techniques, and analytical frameworks to investigate dynamic switching stresses in WBG devices and the integration strategies …

Artificial intelligence powered personality assessment: A multidimensional psychometric natural language processing perspective
… personality assessment. Results showed that measurement reliability is often not addressed in past AI personality assessment research, and that construct validity evidence is lacking. In Study 2, I built an interactive tool to automatically and adaptively prompt for, collect, and analyze …

Electrophysiological correlates of performance monitoring in middle and late adolescence
… system. To date, no studies have examined the measurement reliability of the ERN as a trait-like measure of response monitoring, its development in mid- and late- adolescence as well as its relation to risk-taking and empathic ability, two traits linked to dopaminergic and ACC activity. …

Single-Cell Gene Expression Variation as A Cell-Type Specific Trait: A Study of Mammalian Gene Expression Using Single-Cell RNA Sequencing
… We characterized single-cell RNA sequencing measurements in terms of sensitivity, precision and accuracy through analysis of data generated in a collaborative control project, where known reference RNA was diluted to single-cell levels and amplified using one of three single-cell RNA …

Reliability of Tibial Measurement with Mechanical Response Tissue Analysis
… coefficients of variation of 5%, and in vivo measurements of monkey tibiae have been validated with ex vivo 3-point mechanical bending tests. Human tibial MRTA measurement has achieved between-trial coefficients of variation of only 12%, so a new physical MRTA configuration and improved …

Miniaturization of Electrical Ultrafine Particle Sizers
… exposure monitoring and spatial distribution measurements of ultrafine particles, this dissertation studied the development and miniaturization of electrical ultrafine particle sizers (EUPS). There are three essential components for developing a EUPS unit: a charger to electrically charge the …

Mechanical Response Tissue Analysis: Inter- and Intra-trial Reliability in Assessing Bending Stiffness of the Human Tibia in College Aged Women
… the lower leg. To evaluate the inter- and intra-reliability of tibial EI, 22 healthy women (X + SD: 20.8 + 1.8 yr) were assessed twice daily for three non-consecutive days. Each daily session consisted of five repeated trials. The ulnar EI protocol of McCabe et al. [J Bone and Mineral Res. …

The Role of Ethical Evaluation of Corporate Social Responsibility in the Perception of Corporate Hypocrisy, the Intention of Opinioned Communication and Behavior toward a Firm
… CSR communication. First, this study found sound measurement reliability and validity of the proposed four-item scale of four dimensions in ethical CSR evaluation (i.e., self-interested motives, self-interested outcomes, altruistic motives and altruistic outcomes). Further, this study also …
