Modeling, Simulation, & Visualization Methods: The 2016 International Conference Proceedings

Views: 66
Ratings: (0)

WorldComp is an international conference that serves researchers, scholars, professionals, students, and academicians who are looking to both foster working relationships and gain access to the latest research results. It is being held jointly (same location and dates) with a number of other research conferences; namely, The 2016 World Congress in Computer Science, Computer Engineering, and Applied Computing (WORLDCOMP'16). The Congress is among the top five largest annual gathering of researchers in computer science, computer engineering and applied computing. We anticipate to have attendees from about 85 countries/territories.

Kinematics-Based Simulation and Animation of Articulated

Rovers Traversing Rough Terrain

Mahmoud Tarokh

Department of Computer Science, San Diego State University

San Diego, CA 92182-7720, U.S.A.

Abstract

2. Overview

The paper proposes a simple and computationally efficient method for the modeling and animation of highly articulated rovers traversing rough terrain. The method is based on the propagation of position and orientation velocities through wheels and various joints and linkages of the rover. These velocity equations are combined to form the Jacobian matrix of the rover that relates the position and orientation of the rover to various active (actuated) and passive rover joint variables. A rearrangement of the Jacobian equation allows determining the actuation of suspension joints for balance control to avoid tipover. This is done through a pseudoinverse method which optimizes a balance performance criterion. To illustrate the kinematics modeling and balance control concepts, the method is applied to a rover similar to the NASA’s Sample Return Rover and simulation and animation results are presented.

ABSTRACT

Visualising the complex emergent spatial structure of large-scale agent-based models is a challenge that is only partially addressed by 3D rendering. We explore the use of 3D printing technology to construct physical artifacts from lattice-oriented models such as the Kawasaki and Potts models in 3D. We describe the problems of support structure, resolution and overhangs in constructing physical 3D print models, and describe our work using additive manufacturing technologies including both both Filament Fabrication and Powder-Bed Fabrication. We experimented with cut away approaches to reveal the complex internal structure of the emergent model configurations and we describe our techniques for generating 3D printable artifacts for models of this nature. We found that powder bed technology enabled quite crisp coloured model components, and present some photographic examples of printed complex model system configurations, showing results of quenching and annealing in stochastic lattice simulations.

ABSTRACT

Many agent-based models employ various mechanisms for agents to propagate. We explore different searching patterns influenced by distance and resource abundance. We

find that when higher density of food sources is more influential than distance, the system moves towards higher sustainable population levels for both the predator and prey species. The resource influenced search patterns produce less defined defensive spiral patterned structures than distance driven searching.

SCATTERED DATA MODELING USING A GPU:

A CASE STUDY

B. Cai, Y. Xiao, T. O’Neil, Z. Duan

Department of Computer Science, University of Akron, Akron, Ohio, USA

Abstract - This paper presents a case study on how to use

GPUs to accelerate scattered data modeling in a two-step approach of scattered data visualization. Measurements were made to correlate GPU performance with various modeling parameters.

The following results were obtained: (1)

Adjusting internal modeling parameters belonging to the modeling function has no impact on computing time. (2)

Modeling time is linearly proportional to the size of the intermediate grid. (3) Speedup by the GPU increases as grid size increases. (4) Efficiency of GPU utilization increases as the grid size increases. (5) Data communication between the
