Summary: The visual appearance of materials is influenced by their light transfer properties, environmental factors, and the presence of liquids on porous, rough, or absorbent surfaces. This is a relevant topic in computer graphics, especially when real-time photo-realistic rendering is needed for scenes involving materials interacting with water. The proposed physically inspired technique models and renders appearance changes of absorbent materials when wet, solving interactions between the liquid and object surface and simulating the diffusion phenomenon with real-time performance through GPU acceleration.

Summary: Understanding the principles of climate change is a major challenge for mankind, with a growing focus on the role of forests in recent years. This work advances the simulation of ecoclimates by modeling feedback loops between vegetation, soil, and atmosphere, capturing a range of phenomena that have not been modeled before at a local scale.

Summary: This paper introduces a new physically based algorithm to simulate dynamic avalanches, utilizing the Bingham plastic model and a two-way fluid-solid coupling model for accurate representation. Additionally, a mixed friction model is used to determine avalanche transitions, with an aerodynamics-based snow drag force model to enhance realism in avalanche scenes. By adjusting shear rate and friction parameters, different types of wet and dry avalanches can be realistically rendered.

Summary: In this study, the numerical investigation focused on the effect of rheological behavior of non-Newtonian fluids on Rayleigh-Benard thermosolutal convection instabilities, revealing the presence of bistability convective phenomenon. The study also examined the combined effects of rheology parameters and double diffusive bistability convection. Aiding flow showed the existence of two steady-state solutions for convection, while opposing flows did not exhibit bistability convection.

Summary: In this study, we propose a physics-based combustion simulation method for computer graphics that improves upon previous mathematical models to achieve more realistic flames, temperatures, and soot distributions. Our method incorporates mathematical models for the thermodynamic properties of real-world fuels, enabling the prediction of important parameters such as adiabatic flame temperatures. We also consider heat transfer through convection, conduction, as well as radiative cooling and heating. We apply this method to simulate a wide range of deflagration phenomena, from small-scale flames to fireballs and subsonic explosions, and validate our results using reference footage and measurements.

Summary: This review article summarizes literature on simulations of physically surface-patterned membranes and discusses the various factors affecting their anti-fouling performance, including membrane dimensions, fluid flow velocity and direction, particle size, and pattern size. The review concludes that the pattern dimensions have the most significant influence on the anti-fouling performance.

Summary: Although digital reading has become more accessible thanks to affordable mobile devices and distribution platforms, little effort has been made to improve the digital book reading experience. Many rare and interesting physical books have not been adequately replicated digitally, causing a loss of the true experience. By leveraging static modeling of freeform developable surfaces, a method has been devised to simulate interacting with physical books in a virtual 3D environment in real time on mobile devices.

Summary: We propose an integrated hydrologic modeling approach for the conterminous United States using the SWAT + models of the National Agroecosystem Model (NAM). By simulating groundwater storage and flow in a physically based spatially distributed manner using the gwflow module, we enhance the NAM model. We also develop a scripting tool that automates the creation of gwflow inputs for each 8-digit hydrologic unit code (HUC8) SWAT + model.

Summary: This work reveals an abnormal rate-dependent stress relaxation response of glassy polymers, where a higher initial loading rate leads to a more-activated structure state of the polymers. By introducing the effective temperature model and Adam-Gibbs model, a micro-mechanical model is developed to capture this abnormal behavior successfully.

Summary: In recent years, the diverse structures and unique properties of physically cross-linked hydrogels have attracted significant attention. Compared to chemically cross-linked hydrogels, hydrogels cross-linked with physical interactions using natural polymers have advantages in terms of being environmentally friendly and exhibiting diverse reversible non-covalent bonds. This review aims to provide strategies for designing physically cross-linked hydrogels based on non-covalent bonds derived from functional groups of natural polymers to develop unique properties and extend their applications.

Summary: We developed a physically based equation of state for Mie-6 fluids that has a comparable accuracy to state-of-the-art empirical models. The equation of state combines uv-theory with the third virial coefficient to provide an accurate description of high and low density regimes. The new model has several advantages over empirical models, including applicability to a wider range of repulsive exponents and better description of meta-stable and unstable regions.

Summary: An efficient method for generating geometric winding paths on parametric shapes is introduced, focusing on filament winding technology for producing composite materials. Different methods for convex and non-convex objects are proposed, with considerations for friction and bridging across concavities. The approach forms the basis for a comprehensive design system for creating, visualizing, and redesigning winding paths for various shapes.
