Power transformers play an important role in ensuring efficient and reliable transmission distribution of electrical power. Their failure can lead to significant disruptions power supply safety concerns. Transformer incipient faults may occur due various reasons, including electrical, mechanical or environmental factors. They develop slowly serious damage if not diagnosed corrected time. In thi...

Although immunization is one of the great public health achievements, continued success depends on an available supply of the vaccines that are recommended for routine use. Beginning in 2000, the United States experienced vaccine supply disruptions of unprecedented scope and magnitude. Although most of the supply disruptions have been resolved, it appears that a fragile vaccine supply will be p...

Being able to reliably, and automatically, select variables in linear regression models is a notoriously difficult problem. This research attacks this question head on, introducing not only a computationally efficient algorithm and method, LARS (and its derivatives), but at the same time introducing comprehensive theory explaining the intricate details of the procedure as well as theory to guid...

This research focuses on estimating and understanding the costs and causes of transportation related supply chain disruptions. In-depth interviews with logistics managers were undertaken to investigate how companies perceive transportation related supply chain disruptions and what they are doing to respond and address them. Stated choice experiments were designed to estimate the cost of disrupt...
