Mechanical and Biomedical Engineering Faculty Publications and Presentations
Building energy signature analysis is a well-established tool for understanding the temperature sensitivity of building energy consumption and measuring energy savings. This tool has been used to measure energy savings of residential, commercial, and even industrial buildings. The public availability of electricity loads (i.e., hourly electricity demand (MW)) from entire Balancing Authorities (BAs) provide an interesting opportunity to apply this approach to a large aggregate load. In this paper, we explore that opportunity for BAs and show that the correlations for large geographical areas are surprisingly coherent when the change-point linear regression analysis is used with the daily interval data …
Multidisciplinary Game-Based Approach For Generating Student Enthusiasm For Addressing Critical Infrastructure Challenges, John F. Gardner
Multidisciplinary Game-Based Approach For Generating Student Enthusiasm For Addressing Critical Infrastructure Challenges, John F. Gardner
Mechanical and Biomedical Engineering Faculty Publications and Presentations
Building upon experiences from past course offering,1 several universities across the United States (U.S) have incorporated a critical infrastructure educational game platform as a unifying platform to integrate different disciplines to a common goal. The critical infrastructure backbones of the world provide the delivery mechanisms for energy and other utilities that provide the lifestyle we have come to expect in our society. As these critical infrastructure systems have evolved, the complexity of their integration has generated numerous challenges as a side effect of increased automation that are more pronounced as the infrastructure ages. Although still a modern technological wonder, …
Simulation Of Vertical Axis Wind Turbines With Variable Pitch Foils, L. Damon Woods, John F. Gardner, Kurt S. Myers
Simulation Of Vertical Axis Wind Turbines With Variable Pitch Foils, L. Damon Woods, John F. Gardner, Kurt S. Myers
Mechanical and Biomedical Engineering Faculty Publications and Presentations
A dynamic computer model of a turbine was developed in MATLAB in order to study the behavior of vertical axis wind turbines (VAWTs) with variable pitch (articulating) foils. The simulation results corroborated the findings of several empirical studies on VAWTs. The model was used to analyze theories of pitch articulation and to inform the discussion on turbine design. Simulations of various models showed that pitch articulation allowed Darrieus-style vertical axis wind turbines to start from rest. Once in motion, the rotor was found to accelerate rapidly to very high rotational velocities. The simulations revealed a plateau region of high efficiency …
The Party’S Over: Sustaining Support Programs When The Funding Is Done, John Gardner, Pat Pyke, Cheryl Schrader, Janet M. Callahan, Amy Moll
The Party’S Over: Sustaining Support Programs When The Funding Is Done, John Gardner, Pat Pyke, Cheryl Schrader, Janet M. Callahan, Amy Moll
Mechanical and Biomedical Engineering Faculty Publications and Presentations
In the lifecycle of an engineering education grant, the phase where best practices are sustained and disseminated is perhaps the most crucial stage for maximizing impact. Yet this transition phase often receives the least attention as project team enthusiasm can wane, while funding tapers off, and faculty priorities are pulled in other directions. There are numerous obstacles associated with sustaining program changes, even those perceived as very valuable. Typical challenges are: What happens when the funding runs out? What grant-developed programs should be sustained by the university? Does the institution need to internally allocate resources in an annual budget large …
