A parametric model for real-time flickering fire
ثبت نشده
چکیده
Fire is a complex natural phenomena involving chemical reactions and turbulent flow of hot gaseous products. Significant computer graphics research is devoted to modelling the turbulent dynamics of fire; however flicker which results from the chemical nature of fire has not been previously modelled. In this paper we present a technique that addresses both modelling of dynamics and chemical aspects of fire. We use a stochastic Lagrangian approach to model the dynamics. We formulate a simplified model of thermochemistry that mimics the behavior of models in combustion studies to capture the chemical aspects. The model is parameterized to enable control of flicker rate, flame height and number of flame brushes in the simulated fire. We exploit the programmability of graphics hardware for real-time rendering. The capabilities of the model are demonstrated via representative animations.

Real Time Driver’s Drowsiness Detection by Processing the EEG Signals Stimulated with External Flickering Light
The objective of this study is development of driver’s sleepiness using Visually Evoked Potentials (VEP). VEP computed from EEG signals from the visual cortex. We use the Steady State VEPs (SSVEPs) that are one of the most important EEG signals used in human computer interface systems. SSVEP is a response to visual stimuli presented. We present a classification method to discriminate between...

متن کاملRecognition of Fire Cues during Sleep
Understanding of variations of human behaviour in fire is essential for predicting response to a developing fire. Victims of fire have characteristics that may predispose them to not being aroused from sleep by signals coming from the fire itself. The ability of people without these risk characteristics to wake to fire cues in time to avoid harm has received little attention and it is generally...
متن کاملFunctional-Coefficient Autoregressive Model and its Application for Prediction of the Iranian Heavy Crude Oil Price
Time series and their methods of analysis are important subjects in statistics. Most of time series have a linear behavior and can be modelled by linear ARIMA models. However, some of realized time series have a nonlinear behavior and for modelling them one needs nonlinear models. For this, many good parametric nonlinear models such as bilinear model, exponential autoregressive model, threshold...
