Agent-based simulation of robotic systemsWilliams, Manoleto Z. 06 1900 (has links)
Approved for public release; distribution is unlimited / A goal and behavior agent layer Java Model was developed to simulate cruise, correct and avoid Control Modules in an autonomous agent (robot). The model was tested against a deterministic Figure of Merit (FOM) to predict a "best mix" of agents for the simplistic agent economy parameters given. Future works suggests validation of the model with real agents in a real economy. / Lieutenant, United States Navy

A comparison of computational cognitive models : agent-based systems versus rule-based architecturesOeltjen, Craig L. 03 1900 (has links)
Approved for public release; distribution is unlimited / Increased operational costs and reductions in force size are two of the major factors driving the need for improved computer simulations within the military community. Human performance models are used in various aspects of simulation, including controlling computer generated forces, tactical decision aides, intelligent tutoring systems and new system design. This research makes a comparison between two categories of human performance models, multi-agent systems and rule-based architectures. Each type of model has its own strengths and weaknesses, and is therefore better suited for certain applications. Complex military simulations need human performance models that take advantage of the strengths of more than one type of model. The purpose of this research is to compare the implementation and performance of these two models, and to demonstrate the need for hybrid systems that employ the best aspects of models for a given situation. / Lieutenant Commander, United States Navy

Instrument development and computational studies of time-of-flight mass spectrometersLewin, Mark James, Chemistry, Faculty of Science, UNSW January 2006 (has links)
A computer program to simulate peak shapes from time-of-flight (TOF) mass spectrometers has been developed and significantly improved from a previous, unpublished version. This program can accurately simulate both TOF and orthogonal acceleration TOF mass analyser peak shapes, with contributions from initial ion properties, instrument geometry, and other factors including high voltage ripple and detector response. Grid effects have also been included, and simulations for two mass spectrometers are compared to actual recorded spectra. The dispersive effect on ion trajectories of parallel wires and grids has been computationally studied and a model derived for each case. The model is based on the effect wire geometry has on the intrinsic focussing effect of the grid. The models for parallel wires and rectangular grids have been coded into the simulation program described above, and the effect of grids on peak shapes in TOF mass spectrometers has been studied. Good correlation between simulated and actual peak shapes for rectangular grids was obtained for grids in different rotational orientations. A pulsed lens has been developed to reduce the velocity spread of ions in matrix assisted laser desorption/ionisation (MALDI) ion sources, with the aim to increase sensitivity in orthogonal acceleration TOF mass analysers. The system gave an increase in sensitivity of approximately five times over a range of masses, however instrument resolving power was reduced. A rotating sample stage was developed for MALDI mass spectrometers which offers the potential of high sample density, high positional accuracy and repeatability, and low seek times. The system involves reading the position of a disk mounted with MALDI sample spots and timing the laser pulse to coincide with spot availability at an aperture. The system was successfully used to perform mass calibration by using a calibrant sample located on a separate spot to the analyte. Mass resolved disk imaging was also performed over a disk radius using inks. The mass resolved image compared well to the optical image.

Modeling microarchitecture simulator using object-oriented approachChan, Chung-lun 09 June 2000 (has links)
With the success of the CounterDataFlow Pipeline microarchitecture developed by Oregon State University, there is increasing demand for a highly flexible high-level simulator modeling tool to support the further expansions and studies of the Counterflow pipeline processors family. This work examines the implementation of a Java-based execution-driven simulator modeling tool, bBlocks, which gains flexibility by identifying the independent parts in a micro system and partitioning them into reusable blocks. Two simulators have been constructed to demonstrate the possibility of bBlocks. / Graduation date: 2001
