Some Outstanding Problems in Neutron Transport Computation
As more applications are required of the radiations (e.g., neutrons and photons), be it a nuclear reactor, shielding facility, or a radiation treatment apparatus, the demands on the capability and accuracy of design and analysis are increasing ever to a very high degree. One (perhaps the ultimate) task in designing such a nuclear system is to determine the distribution of the neutrons (and/or p...
متن کاملTweeting and tornadoes
Social Media and micro-blogging is being used during crisis events to provide live up-to-date information as events evolve (before, during and after). Messages are posted by citizens or public officials. To understand the effectiveness of these messages, we examined the content of geo-located Twitter messages (“tweets”) sent during the Moore, Oklahoma tornado of May 20, 2013 (+/-1day) to explor...
متن کاملForecasting Tornadoes in Georgia
Some climatological data on the seasonal, diurnal, and geographical distribut>iorl of tornadoes in Georgia are presented, and the tornado "season" is defined as occurring from February through April. Twelve different storms producing t,ornadoes during one or more 12-hour forecast periods are studied for synoptic similarities. A mean tornado sounding and a 700-mb. composite chart, taken from dat...
متن کاملPhysically-Based Simulation of Tornadoes
In this paper, we present a physically-based model to perform 3D visual simulation of tornadoes. Simulating natural phenomena based on physically realistic models has been an active research area in computer graphics. The tornado phenomenon is a spectacular one as it demonstrates the magnificent strength of forces of nature and its shear size. Previous research on tornadoes have focused either ...
متن کاملBoundary-layer Decoupling Affects on Tornadoes
The North American low-level jet is known to have substantial impacts on the climatology of central and eastern regions of the United States. However, the development of the low-level jet may also have an impact on the low-level shear, which could rapidly alter an environment toward becoming more favorable for producing tornadoes. This study investigates this mechanism’s contribution to enhanci...
