We report an approach targeted to aid design exploration, early decisioning in model refinement, optimization and trade offs. The approach consists of SystemC AMS coupling with a descriptive functional simulator. System engineering tools are typically used in design and analysis of system prototypes captured at very high level. Naturally, in high level analysis accuracy and detail of results is compromised...
Simulation of natural phenomena, such as water and smoke, is a very important topic to increase real time scene realism in video-games. Besides the graphical aspect, in order to achieve realism, it is necessary to correctly simulate and solve its complex governing equations, requiring an intense computational work.Fluid simulation is achieved by solving the Navier-Stokes set of equations, using a...
Simulation applications for military training purposes provide features for building scenarios, simulation of computer generated forces (CGF) or simulation of algorithmic behaviors. There are various commercial application frameworks to support services necessary for tactical simulations such as building scenarios and simulation of forces. However, those frameworks are not always able to meet the...
The warship operation training simulation system is developed based on the HLA (high level architecture), and the design approach of the simulation platform is given. The object model and federate proxy class is designed and the development process of the federation and its components is presented. It is proved in the simulation that the redundant data are greatly decreased in the communication network...
Oil reservoir simulation helps in extracting oil and in optimal well placement. This paper presents the parallelization, development, performance analysis, and profiling of a 2-phase oil-water reservoir simulator on a heterogeneous multi-core STI Cell computer. Despite the largely interdependent nature of the oil reservoir model equations, we obtained speedups of 6x with a 1D reservoir data. We boosted...
In order to simulate biological processes, we use multi-agents system. However, modelling cell behavior in systems biology is complex and may be based on intracellular biochemical pathway. So, we have developed in this study a Fuzzy Influence Graph to model MAPK pathway. A Fuzzy Influence Graph is also called Fuzzy Cognitive Map. This model can be integrated in agents representing cells. Results indicate...
This paper presents a modular architecture of simulation software that is capable of properly capturing Coulomb friction in mechanical systems. The presented architecture is built upon Kikuuwe et al.psilas discrete-time friction model, which is based on the implicit Euler method. The paper reformulates the model into a form that can be integrable through the standard fourth order Runge-Kutta method...
