Georgia Tech HF/E students initiated and managed a multisemester project to experience the nuances of conducting HF/E outside the classroom setting. This article focuses on the lessons learned beyond the classroom: project management, team coordination, communication with non-HF/E team members, application of research methods, and integration of data to prioritize and guide design changes. The goal of this article is to help guide other HF/E students and educators when implementing similar projects by providing the lessons we learned from this experience.
Piezoelectric Wafer Active Sensors In Lamb Wave-Based Structural Health Monitoring, Lingyu Yu, Victor Giurgiutiu
Piezoelectric Wafer Active Sensors In Lamb Wave-Based Structural Health Monitoring, Lingyu Yu, Victor Giurgiutiu
Faculty Publications
Recent advancements in sensors and information technologies have resulted in new methods for structural health monitoring (SHM) of the performance and deterioration of structures. The enabling element is the piezoelectric wafer active sensor (PWAS). This paper presents an introduction to PWAS transducers and their applications in Lamb wave-based SHM. We begin by reviewing the fundamentals of piezoelectric intelligent materials. Then, the mechanism of using PWAS transducers as Lamb wave transmitters and receivers is presented. PWAS interact with the host structure through the shear-lag model. Lamb wave mode tuning can be achieved by judicious combination of PWAS dimensions, frequency value, and …

The Pt/C catalysts were mixed with carbon nanotube (CNT), Nafion™ dispersion and a fiber former, polymer poly-acrylic acid (PAA), to form an ink. The ink was deposited onto aluminum foil attached to a rotating collector via an electrospinning process. The ink composition, mixing procedure, and the E-spin parameters were studied for producing a uniform nanofiber mat on the aluminum substrate. The fiber-mat containing active catalyst ingredients was heat treated and decal transferred onto a Nafion membrane to form a membrane electrode assembly (MEA).

Carbon support corrosion is one of the major degradation mechanisms of polymer electrolyte membrane (PEM) fuel cell. Carbon oxidation occurs in PEM electrode and is accelerated at high potential created by adverse operating conditions and improper distribution of reactants and products [1, 2, 3]. Carbon corrosion can lead to the thinning of the electrode layer and severe performance degradation. The detailed mechanisms of carbon support corrosion induced performance loss are still not fully understood; it is believed that the following events contribute to the decay: (1) structural collapse of the porous electrode due to the loss of carbon; (2) carbon …

Quantifying Cell-To-Cell Variations In Lithium Ion Batteries, Shriram Santhanagopalan, Ralph E. White
Faculty Publications
Lithium ion batteries have conventionally been manufactured in small capacities but large volumes for consumer electronics applications. More recently, the industry has seen a surge in the individual cell capacities, as well as the number of cells used to build modules and packs. Reducing cell-to-cell and lot-to-lot variations has been identified as one of the major means to reduce the rejection rate when building the packs as well as to improve pack durability. The tight quality control measures have been passed on from the pack manufactures to the companies building the individual cells and in turn to the components. This …

Monitoring of fatigue cracking in steel bridges is of high interest to many bridge owners and agencies. Due to the variety of deterioration sources and locations of bridge defects, there is currently no single method that can detect and address the potential sources globally. In this paper, we presented a dual mode sensing methodology integrating acoustic emission and ultrasonic wave inspection based on the use of low-profile piezoelectric wafer active sensors (PWAS). After introducing the research background and piezoelectric sensing principles, PWAS crack detection in passive acoustic emission mode is first presented. Their acoustic emission detection capability has been validated …

A Multiagent Energy Management Control System For Commercial & Industrial Applications, Tyler Wayne Price
A Multiagent Energy Management Control System For Commercial & Industrial Applications, Tyler Wayne Price
Theses and Dissertations
Commercial and industrial customers have increasingly adopted fully-automated demand response (auto-DR) as part of their energy management control strategy to mitigate the effects of rising electricity costs. Some of these customers have also contracted with their power provider to permit voluntary curtailment of power consumption to be negotiated by a human operator. Even still, at the customer-side there are needs to maximize cost savings and automate decision making, and at the provider-side there are needs to reduce peaking demand and demand volatility. This thesis describes a centralized multiagent approach that automatically negotiates demand curtailment with a power provider while making …
