Evaluating The Effectiveness Of Training System Approaches For Highly Complex Flight Training, Maria Bauer

Electronic Theses and Dissertations

This research investigates the Training Effectiveness of a low-cost, PC-based training system when compared with two modes (motion and no motion) of a cab training system with large screen for various aviation flying tasks. While much research on this topic has been done in the past, advances in technology have significantly altered what is considered a "low-cost" "simulator." The technology advances have in effect increased the ability of a "low-cost" "simulator" to deliver desired experiences to the user. These "simulators" often are nothing more than PC training system, with only notional representations of the actual aircraft. This research considers the …

The Effect Of Tidal Inlets On Open Coast Storm Surge Hydrographs: A Case Study Of Hurricane Ivan (2004), Michael Salisbury

Electronic Theses and Dissertations

Florida's Department of Transportation requires design storm tide hydrographs for coastal waters surrounding tidal inlets along the coast of Florida. These hydrographs are used as open ocean boundary conditions for local bridge scour models. At present, very little information is available on the effect that tidal inlets have on these open coast storm tide hydrographs. Furthermore, current modeling practice enforces a single design hydrograph along the open coast boundary for bridge scour models. This thesis expands on these concepts and provides a more fundamental understanding on both of these modeling areas. A numerical parameter study is undertaken to elucidate the …

Comparison Of Subsurface Cavity Investigations Using Earth Resistivity, Seismograph And Ground Penetrating Radar, Dennis M. Filler

Retrospective Theses and Dissertations

Sinkhole formation in the Central Florida area has become a serious problem. The subsurface exploration method for cavity detection is indeed needed prior to sinkhole development. this research study compares the effectiveness of earth resistivity, seismograph and ground penetrating radar (GPR) methods in the detection of subsurface cavities. A resistivity instrument measures a material's resistance to electric currents. The seismograph measure the propagation velocity of a medium refracting compressional waves. The GPR transmits and receives electromagnetic pulses reflecting off subsurface interfaces.

Tests were conducted at two sites: a model test site at the University of central Florida, Orlando, and a …

Experimental Investigation Of Campbell Pacific Nuclear Corporation Mc-1 Density-Moisture Nuclear Gauge On Sand, Clay, Asphaltic Concrete And Concrete, Carl H. Francois

Retrospective Theses and Dissertations

The time-consuming traditional methods of determining soil density and moisture content have been widely replaced by more advanced techniques using radioactive isotopes such as cesium, americium, and beryllium. To ensure the validity and accuracy of the results from a nuclear gauge unit designed by Campbell Pacific Nuclear Corporation, a conventional standard test, the sand cone replacement method, was used in tandem with the nuclear instrument for the density and moisture content determination in sand and clay at different sites. The results of the two methods of measurement agree within close limits. An empirical equation was derived to correlate the data …
