We present an image-editing technique that can synthesize weathering effects with fine-scale geometric variations that occur together with weathering phenomena. We extract such fine-scale geometries as high-frequency components of the image semi-automatically according to the estimated weathering distribution in the image. The geometric details are modified when (de)-weathering is applied, yiel...

Weathering modeling introduces blemishes such as dirt, rust, cracks and scratches to virtual scenery. In this paper we present a visual simulation technique that works well for a wide variety of weathering phenomena. Our technique, called γ-ton tracing, is based on a type of aging-inducing particles called γ-tons. Modeling a weathering effect with γ-ton tracing involves tracing a large number o...

Physicochemical analysis in the microscopic sense is a critical assessment of monitoring the polymeric materials under a weathering test, and it links the accelerated laboratory test with the outdoor performance results for a long-term durability. Here, by taking an experimented example for vinyl siding after an outdoor weathering test in Okinawa, Japan for 17 years and a QUV accelerated weathe...

This study encompasses the analysis of oil spills occurred in Gulf Morrosquillo during loading procedures tankers Coveñas maritime Terminal, by means numerical simulation experiments trajectories and weathering processes spilled, which under specific wind, waves, ocean currents conditions. A three-dimensional (3D) modelling system, OpenOil, is part open-source OpenDrift trajectory framework was...

Mineral carbonation of basic silicate minerals regulates atmospheric CO(2) on geological time scales by locking up carbon. Mining and spreading onto the earth's surface of fast-weathering silicates, such as olivine, has been proposed to speed up this natural CO(2) sequestration ('enhanced weathering'). While agriculture may offer an existing infrastructure, weathering rate and impacts on soil a...

A mathematical model of the evolution marine oil spills with taking into account processes spreading and weathering, has been implemented as a software package called SPILLMOD. In doing so, new Eulerian-Lagrangian method for Computational Fluid Dynamics (CFD) developed in context solving shallow-water-type equations capability to handle situation where advancing/vanishing layer light fluid (oil...

1 Lithologic differences 2 variable silicate weathering fluxes, which provide an important negative feedback on climate over 3 geologic timescales. To isolate the influence of lithology on weathering rates and mechanisms, we 4 compare two nearby catchments in the Luquillo Critical Zone Observatory in Puerto Rico, which 5 have similar climate history, relief and vegetation, but differ in bedrock...
