Investigation Of Nascar Restrictor Plate Manifold Insert Using Wave Engine Simulation And Response Surface Methodology, John Mason Gross Iii
Investigation Of Nascar Restrictor Plate Manifold Insert Using Wave Engine Simulation And Response Surface Methodology, John Mason Gross Iii
Electronic Theses and Dissertations
With the increasing growth in computer processing power, computer based computational fluid dynamics simulations are finding increasing acceptance and use in the field of internal combustion engine development. Once fully developed, such simulations provide detailed and expedient tools for testing existing theories, as well as new ideas. While numerous studies on wave propagation and fluid flow in intakes manifolds exist, most restrict the analysis to a single intake runner and port, examining only the dynamics from the runner-to-plenum junction downstream to the valve. While such analyses provide comprehensive models for wave propagation dynamics in the runner, little is published on …
Decision Support Model For Construction Crew Reassignments, Angela M. Sist
Decision Support Model For Construction Crew Reassignments, Angela M. Sist
Electronic Theses and Dissertations
The reassignment of crews on a construction project in response to changes occurs on a frequent basis. The factors that affect the crew reassignment decision can be myriad and most are not known with certainty. This research addresses the need for a decision support model to assist construction managers with the crew reassignment problem. The model design makes use of certainty factors in a decision tree structure. The research helped to determine the elements in the decision tree, the appropriate combination rules to use with the certainty factors, and the method for combining the certainty factors and costs to develop …
