Asymptotically optimal path planning and surface reconstruction for inspection
… their autonomous inspection. Two essential parts of the inspection problem are (1) path planning and (2) surface reconstruction. On the first problem, we develop a novel analysis of asymptotic optimality of control-space sampling path planning algorithms. This analysis demonstrated that …

Fitts' Law and human control of an electromyographic signal from the biceps brachii muscle group
… two targets on a computer screen. For five out of six subjects, the results were consistent with Fitts' Law with correlation coefficients ranging between 29% and 72%. The low correlation of the sixth subject (0.6%) may have been due to electrode misplacement and the adoption of a "strategy" in …

Microscopic description of the granular fluidity field in nonlocal flow modeling
… nonlocal phenomena. However, the physical nature of the field has not been identified. Here, the granular fluidity is found to be a kinematic variable given by the velocity fluctuation and packing fraction. This is verified with many discrete element simulations, which show the operational …

Assembly cell layout and Kanban system design for an oilfield services company
The thesis describes the layout design of new gauge assembly lab for an oilfield services company. A relationship diagram was created to categorize all the workstations and activities in the assembly line. Three layouts were proposed based on the categorization. One layout that facilitated the …

Computer simulation and analysis of production line with two unreliable full batch machines and a finite buffer
This paper investigates computer simulations of deterministic and exponential models of a production line with full-batch processing and a finite buffer in order to validate the theoretical models already developed, and to gain more insight to the production line behavior through the simulations. …

Quality improvement and control based on defect reduction
… food packaging company now experiencing hundreds of printing defects. Methodologies of Define, Measure, Analyze, Improve, and Control (DMAIC), and Response Surface Model were introduced to reduce the defect rate and control the process. As a result, critical inputs were identified, and a …

Unidirectional inline skates
… the design, manufacture, assembly, and testing of "1WSkates," a pair of inline skates that prevent backwards motion. The defining element of 1WSkates is the use of a one-way bearing which, along with a fixed axle, prevents certain wheels from rolling backwards. The axle is custom-shaped to lock …

Polarity governs atomic interaction through two-dimensional materials
Transparency of two-dimensional (2D) materials to inter-molecular interactions has been an unresolved problem. Previous researchers found that water droplets interact with underlying substrates through graphene, as if the graphene is "transparent". However, graphene's transparency determined by …
