Physics-Based Wildfire Model Track: EMS, Fire, Disaster Management Author(s): Charles Hall An advanced, physics-based supercomputer/GIS wildfires modeling system has been developed that incorporates chemistry, radiation physics, the local weather and its decisive two-way interactions with the fire, the effects of complex terrain on weather and fire behavior, and represents fuel in three dimensi...

astrophysics is becoming now an integral part of general physics. considering the black hole theory ,which is a new and exciting branch of relativistic astrophysics, we see many connections between elementary particle physics and astrophysics. in this article we attempt to explain the development of star physics ,in an easy ,understandable manner. previous knowledge of relativistic theory or cl...

An understanding of a scene's causal physics|how scene elements interact and respond to forces|is a precondition to reasoning about how the scene came to be, how it may evolve in time, and how it will respond to manipulation. We propose a computationally inexpensive method for recovering causal structure from images, in which which a scene model is built incrementally through interleaved sensin...

To outsiders, it might seem natural—obvious, even—that you could use physics to make animated characters move in games and movies. The surprising fact is that physics-based characters have never been very successful in production. However, over the last few years, physicsbased character animation has been experiencing tremendous growth and a great deal of attention in computer graphics research...

The first part of this paper reviews some physics issues representing major computational challenges for global MHD models of the space environment. These issues include: (i) mathematical formulation and discretization of the governing equations that ensure the proper jump conditions and propagation speeds, (ii) regions of relativistic Alfvén speed, (iii) regions dominated by strong intrinsic p...

Geometric modeling has proved to be crucial to computer graphics and computer aided geometric design CAGD During the past several decades numerous geometric formulations have been proposed for a large variety of geometric modeling applications In this paper we survey the diversity of shape representations ranging from the primitive polynomial to the sophisticated Non Uniform Rational B Spline N...
