Analysis of Devonian Black Shales in Kentucky for Potential Carbon Dioxide Sequestration and Enhanced Natural Gas Production Quarterly Report: April-June 2003

Description: CO{sub 2} emissions from the combustion of fossil fuels have been linked to global climate change. Proposed carbon management technologies include geologic sequestration of CO{sub 2}. A possible, but untested, sequestration strategy is to inject CO{sub 2} into organic-rich shales. Devonian black shales underlie approximately two-thirds of Kentucky and are thicker and deeper in the Illinois and Appalachian Basin portions of Kentucky than in central Kentucky. The Devonian black shales serve as bo… more

Angular and Linear Velocity Estimation for a Re-Entry Vehicle Using Six Distributed Accelerometers: Theory, Simulation and Feasibility

Description: This report describes a feasibility study. We are interested in calculating the angular and linear velocities of a re-entry vehicle using six acceleration signals from a distributed accelerometer inertial measurement unit (DAIMU). Earlier work showed that angular and linear velocity calculation using classic nonlinear ordinary differential equation (ODE) solvers is not practically feasible, due to mathematical and numerical difficulties. This report demonstrates the theoretical feasibility of u… more

A C++ Infrastructure for Automatic Introduction and Translation of OpenMP Directives

Description: In this paper we describe a C++ infrastructure for source-to-source translation. We demonstrate the translation of a serial program with high-level abstractions to a lower-level parallel program in two separate phases. In the first phase OpenMP directives are introduced, driven by the semantics of high-level abstractions. Then the OpenMP directives are translated to a C++ program that explicitly creates and manages parallelism according to the specified directives. Both phases are implemented u… more
