Smooth Trajectory Generation for Machine Tools and Industrial Robots

Creator:: Tajima, Shingo
Abstract:: This thesis presents accurate and time-optimal smooth reference trajectory generation techniques for manufacturing equipment such as high-speed machine tools (MT) and industrial robots (IR). Typical machining tool-paths for MTs and IRs are defined as a series of discrete linear moves. Although Point-to-Point (P2P) feed motion can be generated by interpolating...

Geometry of Locomotion

Creator:: Ramasamy, Suresh
Abstract:: Many animals and robots move through the world by coupling cyclical changes in shape called gaits to an interaction with the environment. Because mobility is an important aspect of such robots, a key metric when evaluating design and performance of mobile robots is the efficiency of their optimal gaits. The...

Automated decomposition of complex parts for manufacturing with advanced joining processes

Creator:: Massoni, Brandon R.
Abstract:: Recent advancements in joining operations and additive manufacturing now allow complex metal parts to be built up from raw materials, as opposed to being machined down from solid blocks. This not only opens up the design space, but also allows for much more efficient manufacturing. By decomposing a complex part...

Orb Web Vibrations: Modeling, Localization, and Measurement

Creator:: Otto, Andrew W.
Abstract:: The orb web is a multipurpose structure---serving as a home for its inhabitant spider, as a prey capture device, and as a physical extension of the spider’s sensing abilities. Biologists are particularly interested in the spider’s ability to locate prey trapped in its web by sensing the vibrations induced from...

Investigation of Iron Passivity and Chloride-induced Depassivation in Alkaline Electrolytes using Reactive Force Field Molecular Dynamics (ReaxFF-MD)

Creator:: Dormohammadi, Hossein
Abstract:: The corrosion and passivity of iron (and carbon steel) in media with different alkalinity as well as iron depassivation have been studied extensively using electrochemical methods and nano-scale surface characterization studies. The electrochemical techniques provide valuable information about the average electrochemical behavior of relatively large metal surfaces, typically in centimeter-square...

Seasonal thermoregulation in the dark-eyed junco (Passeriformes: Junco hyemalis)

Creator:: Swanson, David Leslie
Abstract:: Winters in north-temperate climates impose high thermogenic demands upon small birds which are met by seasonal acclimatization. This thesis investigates the extent and mechanisms of seasonal acclimatization in darkeyed juncos (Junco hyemalis) inhabiting western Oregon. Although insulation is significantly increased in winter, acclimatization is primarily metabolic. Increased metabolism is required...

A study of the photolysis of the aqueous thymine system at 214 nm, 229 nm and 254 nm

Creator:: Satcher, Robert Lee
Abstract:: The photolysis of the aqueous thymine system has been investigated at 214 nm, 229 nm and 254 nm at room temperature. Products of photolysis have been identified as hydrogen peroxide, 6-hydroxy-5- hydroperoxy thymine and tentatively 5-hydroxy-6-hydroperoxy thymine. These together with thymine loss, were determined quantitatively under a variety of conditions....
