Feasible Form Parameter Design Of Complex Ship Hull Form Geometry, Thomas L. Mcculloch
Feasible Form Parameter Design Of Complex Ship Hull Form Geometry, Thomas L. Mcculloch
University of New Orleans Theses and Dissertations
This thesis introduces a new methodology for robust form parameter design of complex hull form geometry via constraint programming, automatic differentiation, interval arithmetic, and truncated hierarchical B- splines. To date, there has been no clearly stated methodology for assuring consistency of general (equality and inequality) constraints across an entire geometric form parameter ship hull design space. In contrast, the method to be given here can be used to produce guaranteed narrowing of the design space, such that infeasible portions are eliminated. Furthermore, we can guarantee that any set of form parameters generated by our method will be self consistent. It …
Measuring Presence In A Police Use Of Force Simulation, Dharmesh Rajendra Desai
Measuring Presence In A Police Use Of Force Simulation, Dharmesh Rajendra Desai
University of New Orleans Theses and Dissertations
We have designed a simulation that can be used to train police officers. Digital simulations are more cost-effective than a human role play. Use of force decisions are complex and made quickly, so there is a need for better training and innovative methods. Using this simulation, we are measuring the degree of presence that a human experience in a virtual environment. More presence implies better training. Participants are divided into two groups in which one group performs the experiment using a screen, keyboard, and mouse, and another uses virtual reality controls. In this experiment, we use subjective measurements and physiological …
Data Visualization To Evaluate And Facilitate Targeted Data Acquisitions In Support Of A Real-Time Ocean Forecasting System, Edward A. Holmberg Iv
Data Visualization To Evaluate And Facilitate Targeted Data Acquisitions In Support Of A Real-Time Ocean Forecasting System, Edward A. Holmberg Iv
University of New Orleans Theses and Dissertations
A robust evaluation toolset has been designed for Naval Research Laboratory’s Real-Time Ocean Forecasting System RELO with the purpose of facilitating an adaptive sampling strategy and providing a more educated guidance for routing underwater gliders. The major challenges are to integrate into the existing operational system, and provide a bridge between the modeling and operative environments. Visualization is the selected approach and the developed software is divided into 3 packages: The first package is to verify that the glider is actually following the waypoints and to predict the position of the glider for the next cycle’s instructions. The second package …
Hydrographic Surface Modeling Through A Raster Based Spline Creation Method, Julie G. Alexander
Hydrographic Surface Modeling Through A Raster Based Spline Creation Method, Julie G. Alexander
University of New Orleans Theses and Dissertations
The United States Army Corp of Engineers relies on accurate and detailed surface models for various construction projects and preventative measures. To aid in these efforts, it is necessary to work for advancements in surface model creation. Current methods for model creation include Delaunay triangulation, raster grid interpolation, and Hydraulic Spline grid generation. While these methods produce adequate surface models, attempts for improved methods can still be made.
A method for raster based spline creation is presented as a variation of the Hydraulic Spline algorithm. By implementing Hydraulic Splines in raster data instead of vector data, the model creation process …
