Electronic Conduction and Ionic Diffusion in (Bi₀.₅Na₀.₅)TiO₃-(Bi₀.₅K₀.₅)TiO₃-based Thin Films, Electronic Conduction and Ionic Diffusion in (Bi0.5Na0.5)TiO3-(Bi0.5K0.5)TiO3-based Thin Films

Creator:: Walenza-Slabe, Joel
Abstract:: Solid solutions based on the perovskite ferroelectrics Bi₀.₅Na₀.₅TiO₃ (BNT) and Bi₀.₅K₀.₅TiO₃ (BKT) might someday replace current Pb-based ferroelectric and piezoelectric devices. This is one goal of the Restrictions on Hazardous Substances (RoHS) guidelines seeking to limit Pb in consumer devices. Although the Bi-based ferroelectrics are well suited to the task...

Automated feature extraction for orientation and slicing in microlamination

Creator:: Ariastuti, Retna
Abstract:: The research is about developing a computerized design system for microtechnology-based energy, and chemical systems (MECS). MECS devices are a part of microfabrication, which primarily focuses on taking advantage of the extremely high rates of heat and mass transfer available in microstructures. It typically consists of intricate arrays of components...

Energy Analysis of Novel Data Center Cooling Technology : Evaporative Cooling System Operation and Microchannel Heat Exchanger Manufacturing

Creator:: Lajevardi, Babak
Abstract:: Worldwide, many organizations are pursuing higher energy efficiency by reducing power consumption of their processes, systems, and supporting infrastructure. The rapid growth of the information technology (IT) industry and the miniaturization of semiconductors have resulted in substantial increases in energy consumption and power density of IT equipment, and, subsequently, heat...

Automated Assembly Planning : From CAD Model to Virtual Assembly Process

Creator:: Rafibakhsh, Nima
Abstract:: Assembly planning is a crucial task for every manufacturing product. In general, assembly operations consume more than 30% of the total manufacturing time and cost. Therefore, any effort in optimizing assembly will have a significant impact on the economic success of manufacturing. Finding an optimal assembly plan by hand is...

Chemical Solution Deposition and Advanced Characterization of Pb-free, Bi-based, Piezoelectric Thin Films

Creator:: Mason, Ashley D.
Abstract:: Piezoelectric materials convert mechanical strain into a dielectric displacement, as well as the converse, allowing these materials to be used as sensors, actuators, and transducers. Currently, lead zirconate titanate (PZT) is the primary material used in these applications. Due to environmental toxicity and safety concerns associated with Pb, development of...

A framework for integrating systems thinking into sustainable manufacturing

Creator:: Zhang, Hao
Abstract:: Improving the understanding the relations of sustainability behaviors in manufacturing systems and actively engaging with manufacturers (especially SMEs) in sustainability efforts is key to the long-term success of U.S. industry and the natural environment. This study addresses this urgent need by establishing a systemic approach for the design of costing...

Development, characterization, and piezoelectric fatigue behavior of lead-free perovskite piezoelectric ceramics

Creator:: Patterson, Eric Andrew
Abstract:: Much recent research has focused on the development lead-free perovskite piezoelectrics as environmentally compatible alternatives to lead zirconate titanate (PZT). Two main categories of lead free perovskite piezoelectric ceramic systems were investigated as potential replacements to lead zirconate titanate (PZT) for actuator devices. First, solid solutions based on Li, Ta,...

Multivariate control charts for nonconformities

Creator:: Chattinnawat, Wichai
Abstract:: When the nonconformities are independent, a multivariate control chart for nonconformities called a demerit control chart using a distribution approximation technique called an Edgeworth Expansion, is proposed. For a demerit control chart, an exact control limit can be obtained in special cases, but not in general. A proposed demerit control...

About good work

Creator:: Lee, Wei-Tau
Abstract:: This research is an effort to explore the nature of good work, a concept that describes work that is beneficial to the physical, psychological, and social dimensions of its stakeholders, including and especially the worker. This effort is divided into four distinct parts. First, the construct of good work is...
