Low Cost/ High Precision Flight Dynamics Estimation Using The Square-Root Unscented Kalman Filter, Trevor H. Paulsen Oct 2009

Low Cost/ High Precision Flight Dynamics Estimation Using The Square-Root Unscented Kalman Filter, Trevor H. Paulsen

Theses and Dissertations

For over a decade, Brigham Young University's Microwave Earth Remote Sensing (MERS) team has been developing SAR systems and SAR processing algorithms. In order to create the most accurate image reconstruction algorithms, detailed aircraft motion data is essential. In 2008, the MERS team purchased a costly inertial measurement unit (IMU) coupled with a high precision global positioning system (GPS) from NovAtel, Inc. In order to lower the cost of obtaining detailed motion measurements, the MERS group decided to build a system that mimics the capability the NovAtel system as closely as possible for a much lower cost. As a first …


A Comprehensive Integration And Analysis Of Dynamic Load Balancing Architectures Within Molecular Dynamics, Christopher Reed Rogers May 2009

A Comprehensive Integration And Analysis Of Dynamic Load Balancing Architectures Within Molecular Dynamics, Christopher Reed Rogers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The world of nano-science is an ever-changing field. Molecular Dynamics (MD) is a computational suite of tools that is useful for analyzing and predicting behaviors of substances on the molecular level. The nature of MD is such that only a few types of computations are repeated thousands or sometimes millions of times over. Even a small increase speedup or efficiency of an MD simulator can compound itself over the life of the simulation and have a positive and observable effect. This thesis is the end result of an attempted speedup of the MD problem. Two types of MD architectures are …
