Visibility-based pursuit-evasion in an unknown planar environment

by Shai Sachs, Stjepan Rajko, Steven M. Lavalle - International Journal of Robotics Research , 2004
"... We address an on-line version of the visibility-based pursuit-evasion problem. We take a minimalist approach in modeling the capabilities of a pursuer robot. A point pursuer moves in an unknown, simplyconnected, piecewise-smooth planar environment, and is given the task of locating any unpredictable ..."

ROADMAP-BASED TECHNIQUES FOR MODELING GROUP BEHAVIORS IN MULTI-AGENT SYSTEMS

by Samuel Oscar Rodriguez , 2012
"... Simulating large numbers of agents, performing complex behaviors in realistic environments is a difficult problem with applications in robotics, computer graphics and animation. A multi-agent system can be a useful tool for studying a range of situations in simulation in order to plan and train for ..."
Abstract - Add to MetaCart
a roadmap-based approach with agent-based systems for groups of agents performing a wide range of behaviors. The system that we have developed is highly customizable and allows us to study a variety of behaviors and scenarios. The system is tunable in the kinds of agents that can exist

Particle-Based Fluid Simulation for Interactive Applications

by Matthias Müller, David Charypar, Markus Gross , 2003
"... Realistically animated fluids can add substantial realism to interactive applications such as virtual surgery simulators or computer games. In this paper we propose an interactive method based on Smoothed Particle Hydrodynamics (SPH) to simulate fluids with free surfaces. The method is an extension ..."

of the SPH-based technique by Desbrun to animate highly deformable bodies. We gear the method towards fluid simulation by deriving the force density fields directly from the Navier-Stokes equation and by adding a term to model surface tension effects. In contrast to Eulerian grid-based approaches

Realistic and Useful: Toward Better Estimates

by Carlo Pescio
"... The PERT technique of three estimates is a traditional, well-known approach to expert estimation. Estimators are asked for their optimistic, most likely and pessimistic estimation; then, a beta probability distribution is built to fit the data. Having a probability distribution for each activity all ..."

approach that has been proven to increased realism. However, Jørgensen’s technique is not directly based on a probability distribution, and therefore it is not directly possible to apply a Montecarlo simulation. Here a novel approach, unifying Jørgensen’s technique and PERT 3 estimates, is proposed

Towards Using Realistic Chemical Kinetics in Multidimensional CFD

by Long Liang, Ellen Meeks
"... This paper presents several advanced solution strategies for overcoming the CPU time barrier associated with solving realistic fuel chemistry in multidimensional CFD. The strategies include a dynamic multi-zone (DMZ) partitioning scheme, a dynamic adaptive chemistry (DAC) scheme, and an advanced ODE ..."
