An Evaluation Of Vibration And Other Effects On The Accuracy Of Grip And Push Force Recall, Thomas W. Mcdowell
An Evaluation Of Vibration And Other Effects On The Accuracy Of Grip And Push Force Recall, Thomas W. Mcdowell
Graduate Theses, Dissertations, and Problem Reports
Operators of vibratory hand tools can be at risk of developing health problems associated with repeated forceful actions and exposure to intense hand-transmitted vibration. To better assess health risks, comprehensive risk evaluations of these tasks must include quantitative assessments of hand-tool coupling forces. Researchers have used instrumentation for such measurements; but those techniques may be ill-suited for certain field environments. Psychophysical force-recall techniques have been proposed as alternatives to handle instrumentation. This study comprised two experiments that examined the effects of vibration and other factors upon force-recall accuracy and reliability. In each experiment, participants applied specific grip and push forces …

Minimizing The Makespan In A Flexible Flowshop With Sequence Dependent Setup Times, Uniform Machines, And Limited Buffers, Bret Crowder
Minimizing The Makespan In A Flexible Flowshop With Sequence Dependent Setup Times, Uniform Machines, And Limited Buffers, Bret Crowder
Graduate Theses, Dissertations, and Problem Reports
This research addresses the problem of minimizing the makespan in a flexible flowshop with sequence dependent setup times, uniform machines, and limited buffers. A mathematical model was developed to solve this problem. The problem is NP-Hard in the strong sense and only very small problems could be solved optimally. For exact methods, the computation times are long and not practical even when the problems are relatively small. Two construction heuristics were developed that could find solutions quickly. Also a simulated annealing heuristic was constructed that improved the solutions obtained from the construction heuristics. The combined heuristics could compute a good …
Relationship Between Damper Resistance And Damper Insertion Depth, Ranjit Jangam
Relationship Between Damper Resistance And Damper Insertion Depth, Ranjit Jangam
Graduate Theses, Dissertations, and Problem Reports
Experiments were performed to determine a predictive model for sliding gate damper resistance (Xdamper). Independent variables included eight ratios of insertion depth (I) to duct diameter (D), two different values of D, four different levels of air velocity, two damper orientations, and two damper edges (Concave/Straight). Analysis of Log (Xdamper) values showed a highly linear relationship with I/D and high statistical significance (p<0.05) for all independent variables and for most two-way interactions. Nearly the entire regression model (R2 = 0.985) was explained by I/D, so all but I/D and Edge were dropped from the final model: Y Log(Xdamper) = -1.434 + 0.089*(Edge) + 4.30*( I/D) (R2 = 0.978). The resulting predictive model: Xdamper = 0.037*10(0.089*(Edge )+4.3*I/D). However error for untransformed Xdamper increased sharply with increasing (I/D) and percent errors were as high as 125% across all values of (I/D). Hence the predictive models are useful for only initial rough adjustment and should be followed by final trial and error adjustment to goal air flow.

Solution Techniques For A Crane Sequencing Problem, Jin Shang
Graduate Theses, Dissertations, and Problem Reports
In shipyards and power plants, relocating resources (items) from existing positions to newly assigned locations are costly and may represent a significant portion of the overall project budget. Since the crane is the most popular material handling equipment for relocating bulky items, it is essential to develop a good crane route to ensure efficient utilization and lower cost. In this research, minimizing the total travel and loading/unloading costs for the crane to relocate resources in multiple time periods is defined as the crane sequencing problem (CSP). In other words, the objective of the CSP is to find routes such that …
