The goal of the 2009 food package revision of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) was to promote a healthier diet among the participant population by prescribing healthier versions of WIC foods. This study examines whether there was a structural...

This thesis first considers some extensions of the existing discrete choice models. One such extension is to use the scale mixture of multivariate normal distributions for the random part of the utility in a random utility maximization framework. By doing so, we expand the horizon of discrete...

Due to advantages such as high energy density, high power density, rapid charge and discharge, high cyclic-life, and environmentally friendly, flywheel energy storage systems (FESs) are widely used in various fields. However, the performance of FES systems depends on the performance of a high...

This paper investigated a 12-slot/11-pole flux switching permanent magnet (FSPM) machine used for electric vehicles (EVs). Five novel rotor teeth shapes are proposed and researched to reduce the cogging torque and torque ripple of the FSPM machine. These rotor teeth shapes are notched teeth,...

This paper presents a novel five-phase permanent magnet synchronous motor (PMSM), which contains dual rotors and a single stator, equivalent to two five-phase motors working together. Thus, this kind of motor has the potential of good fault tolerant capability and high torque density, which...

The main goal of this was to examine the impact of the SNAP program on the allocation of food and nonfood spending expenditures across six subgroups: food, utilities, apparel, transportation, medical care, and other nonfood spending. The empirical analysis is conducted using a consumer demand...

This study extends the early empirical evidence of sentiment risk spillovers on firms within the same category (Barberis, Shleifer and Wurgler, 2005) and across the overlapping category (Ambrose et al., 2007) to other firms in a non-overlapping but correlated category. Using the first six REITs'...

Assortment optimization is a fundamental problem in revenue management, in which the objective usually is to select a subset of products to offer to customers in order to maximize expected revenue or profit. However, business practices often involve multiple, and potentially conflicting goals....

Motivated by several interesting features of the highway mowing auction data from Texas Department of Transportation (TDoT), we propose a two-stage procurement auction model with endogenous entry and uncertain number of actual bidders. Our entry and bidding models pro vide several interesting...
