This paper summarizes the results of a two year project led by the Naval Facilities Engineering and Expeditionary Warfare Center to demonstrate the potential for the patented I2 Vapor Infusion (I2 VP) system to reduce the rate of foul within Department of Defense shipboard heat exchangers (HX). Fouling of DoD shipboard heat exchangers is a chronic and costly operating problem that requires sign...

Vector Space Models (VSM) have been widely used in the language assessment field to provide measurements of students’ vocabulary choices and content relevancy. However, training reference vectors (RV) in a VSM requires a time-consuming and costly human scoring process. To address this limitation, we applied unsupervised learning methods to reduce or even eliminate the human scoring step require...

In this paper, a prediction model is presented that estimates the evacuation time in an emergency situation for hospitals. The model is generic enough to be used in various hospital settings. This model can provide incident managers with estimates of the evacuation times of different types of patients and can offer support to the managers with their resource allocation decisions in emergency si...

Classic ways of gathering data on human behaviour are time-consuming, costly, and are subject to limited participant pools. Gamification provides a motivation to participate, but also requires the development of specialized, research-question specific games that can be costly to produce. Our solution leverages the popular Freemium model of play to motivate voluntary participation by rewarding p...

In this paper, we extend the finance constrained economy proposed by Woodford (1986) to incorporate unions, imperfectly insured unemployment and transfers. We show that this simple extension of the Woodford model changes drastically its stability conditions and local dynamics around the deterministic steady state. By contrast to most related models in the literature, we find that sunspots and d...
