Development of acoustic emissions testing procedures applicable to conventionally reinforced concrete deck girder bridges subjected to diagonal tension cracking

Creator:: Lovejoy, Steven C.
Abstract:: A need exists to develop a non-destructive testing technique that can identify the formation and propagation of diagonal tension cracks in conventionally steel reinforced concrete deck girder (RCDG) highway bridges in the State of Oregon. Such a technique could be included into a structural health monitoring (SHM) system installed on...

Human gait analysis by gait pattern measurement and forward dynamic model combined with non linear feedback control

Creator:: Ko, Seung-uk
Abstract:: Normal gait of human is believed to be an adapted motor control result of optimal behavior of individual. Normal gait would be altered by aging or injury without being perceived. Subtle changes in gait which is not easy to detect, can cause many serious problems including joint pains and even...

Evaluation of total hip arthroplasty research in the US and Europe

Creator:: Simmons, Marcy J.
Abstract:: Background: Hip replacements are considered routine operations which improve the quality of life in patients by reducing pain and restoring function. There are many variations in prostheses with varying benefits and disadvantages. Methods: Literature from the United States and Europe was collected on total hip replacements between 2001 and the...

Engineering design knowledge management and capture using a process overview document

Creator:: Zarins, Andis M.
Abstract:: An experiment was conducted to examine the possible impact of an engineering design and problem solving process overview document on knowledge management and capture. A process overview document was first created. Next, two multi-disciplinary design teams worked over a two-week span to develop concepts to address a problematic opportunity. One...

Mixed reactant single chamber fuel cell, using products generated from the electrolysis of an aqueous electrolyte

Creator:: Jost, William C.
Abstract:: A Mixed Reactant Single Chamber (MRSC) Fuel Cell is a relatively recent concept in the field of fuel cell engineering originally developed in the late 1950’s. Typical fuel cells have separated reactants (a separated fuel and oxidizer) that react on their usually non-selective electro-catalytic materials. A mixed reactant fuel cell...

A technique for spatially resolved wall temperature measurements in microchannel heat sinks using infrared thermography

Creator:: Krebs, Daniel P.
Abstract:: A non-intrusive measurement technique for direct quantitative thermal visualization of channel wall temperatures in two phase microchannel flows using infrared thermography (IRT) is presented. Specifically, the measurement of top channel wall temperatures in a fractal-like branching microchannel silicon heat sink during flow boiling is demonstrated and thoroughly documented. Obtaining quantitative...

Detection and analysis of separated flow induced vortical structures

Creator:: Snider, Stephen David Louis
Abstract:: Flow separation is an important phenomenon in fluid dynamics because of the effect it has on lift and drag on immersed bodies. Areas of swirl within a separated flow region may have a distinct effect on the surface forces, modifying the lift and drag characteristics. A correlation between the passage...

The fracture toughness of medium density fiberboard and other fiber bridging composites

Creator:: Matsumoto, Noah T.
Abstract:: In many composites, fiber bridging develops as part of the fracture process. Fiber bridging invalidates many toughness evaluation methods such as the ASTM E399 and complicates the identification of crack length, which is a necessary parameter in energy methods. In order to measure the toughness of fiber bridging composites, an...

Mechanical engineering design across cultures : a method of designing for cultures

Creator:: Van Bossuyt, Douglas L.
Abstract:: Mechanical design is often based on formal methodologies such as Quality Function Deployment. Techniques to quantitatively account for attractability, sensory perception, and affective design have been successfully incorporated into these methods and are receiving growing acceptance across many industries. Although the adoption of these methods marks a large improvement for...

Failure analysis of pre-notched composite laminated plates under four-point bending conditions

Creator:: Arias Gonzales, Sergio
Abstract:: Ever since composite laminate technology was introduced into the aerospace and automotive industry, there has been a need to fully understand the damage progression experienced by composite laminated plates in the presence of a notch. While numerous research studies have been conducted on this matter when subjected to in-plane loads,...
