Procedural City Generation With Combined Architectures For Real-Time Visualization, Griffin Poyck May 2023

Procedural City Generation With Combined Architectures For Real-Time Visualization, Griffin Poyck

All Theses

The work and research of this paper sought to build upon traditional city generation and simulation in creating a tool that both realistically simulates cities and their prominent features and also creates aesthetic and artistically rich cities using assets that combine several contemporary or near contemporary architectural styles. The major city features simulated are the surrounding terrain, road networks, individual buildings, and building placement. The tools used to both create and integrate these features were created in Houdini with Unreal Engine 5 as the intended final destination. This research was influenced by the city, town, and road networking of Ghost …

Numerical Modeling Of Contaminant Transport In Fractured Porous Media Using Mixed Finite Element And Finite Volume Methods, Chen Dong Aug 2010

Numerical Modeling Of Contaminant Transport In Fractured Porous Media Using Mixed Finite Element And Finite Volume Methods, Chen Dong

All Theses

A mathematical model for contaminant species passing through fractured porous media is presented. In the numerical model, we combine two locally conservative methods, i.e. mixed finite element (MFE) and the finite volume methods. Adaptive triangle mesh is used for effective treatment of the fractures. A hybrid MFE method is employed to provide an accurate approximation of velocities field for both the fractures and matrix which are crucial to the convection part of the transport equation. The finite volume method and the standard MFE method are used to approximate the convection and dispersion terms respectively. Numerical examples in different fractured media …

A Middle-Ware Level Client Cache For A High Performance Computing I/O Simulator, Michael Bassily Dec 2007

A Middle-Ware Level Client Cache For A High Performance Computing I/O Simulator, Michael Bassily

All Theses

This thesis describes the design and run time analysis of the system level middle-ware cache for Hecios. Hecios is a high performance cluster I/O simulator. With Hecios, we provide a simulation environment that accurately captures the performance characteristics of all the components in a clusterwide parallel file system. Hecios was specifically modeled after PVFS2. It was designed to be extensible and to easily allow for various component modules to be easily replaced by those that model other system types. Built around the OMNeT++ simulation package, Hecios' inner-cluster communication module is easily adaptable to any TCP/IP based protocol and all standard …

Bioanalyze: A Tool For The Simulation And Analysis Of Biological Systems, James Norman Aug 2007

Bioanalyze: A Tool For The Simulation And Analysis Of Biological Systems, James Norman

All Theses

Scientists have turned to a more systemic approach to biology in order to fully understand the complex functionality of living organisms. Biologist and Geneticist have compiled an impressive amount of experimental data for a multitude of biological systems. Modeling and simulation of these systems has become a prominent tool in the field of Systems Biology. In this paper we present a review of General Systems Theory, Systems Biology, and introduce BioAnalyze. BioAnalyze is a web application designed to simulate, and analyze, the functional dynamics of biological systems.
