A trade space model for robotic lunar exploration
… quantitative methodology for exploring the trade space of potential in situ robotic lunar spacecraft designs. A science value model was developed, using Multi-Attribute Utility Theory (MAUT), to estimate the effectiveness of a spacecraft design towards assessing a set of specified science …

Definition of Damage Volumes for the Rapid Prediction of Ship Vulnerability to AIREX Weapon Effects
… of the vulnerability of a ship concept design to AIREX weapon effects. The model uses simplified physics-based and empirical equations, threat charge size, geometry of the design, and the structure of the design as inputs. The damage volumes are customized to the design being assessed …

Nuclear Electric Propulsion with Low Enriched Uranium
Most space missions have used monopropellant or fuel-oxidiser propulsion systems to provide the required delta-v for orbital transfers and other in-space manoeuvres. Electric propulsion offers an alternative means of providing thrust that makes much more economical use of propellant due to its very …

A sequential adaptive sampling technique based on a local linear model for computer experiment applications
The objective of this dissertation research is to develop a model independent sequential adaptive sampling technique for surrogate model (SM) applications based on a local linear model. This technique, called Nearest Neighbors Adaptive Sampling (NNAS), is conceived to be conceptually simple, …

A tool for model-based engineering
… and complexity of the overall system. In the design and development process, system level performance analysis should precede implementation in order to save cost and to optimize the system architecture during a relatively earlier development phase when such changes are less costly to make. To …

Investigating Single Precision Floating General Matrix Multiply in Heterogeneous Hardware
… Synthesis compiler allows users to architect new designs for reconfigurable hardware using C/C++. Using the HARPv2 as a vehicle for exploration, we investigate the utility of several of the most notable matrix multiplication optimizations to better understand the performance portability of OpenCL …
