The interaction of thermal radiation with conduction and laminar natural convection in a vertical circular pin, situated at participating gas, is numerically investigated. An absorbing and emitting gas is considered, and treated to be a gray participating media. Under the idealizing of gray gas, the Rosselan4 approximation is employed to describe the radiative heat flux in the energy equation. ...

Background. World Health Organization pointed out in 2019 that insufficient physical activity has become the fourth major risk factor affecting global mortality. Objectives. This research explores the influence of multi-media teaching intervention in the physical education curriculum on college students’ sports attitudes and behavior. Methods. The subjects of weight training and Yogalates cou...

Rendering participating media is important to the creation of photorealistic images. Participating has a translucent aspect that comes from light being scattered inside material. For materials with small mean-free-path (mfp), multiple scattering effects dominate. Simulating these computationally intensive, as it requires tracking large number events Existing approaches precompute material and s...

This report summarizes my research on the visualization of scalar fields and the rendering of participating media. A strong focus of my work is on the development of optical models for exploring and visualizing volumetric data sets interactively. In particular, my research is concentrated on goal-oriented optical models that offer simple control over the visual properties of a visualization com...

In a world dominated by social media, the ways in which libraries market to and interact with their users have changed dramatically. The question is not if you should use social media, it is how to use it effectively. It is easy to get a free account on one of the hundreds of social media sites that exist, and chances are your library is already participating on one of these sites. However, man...

The purpose of this study is to investigate the effect of radiation heat transfer on temperature distribution and heat flux to the walls of a diesel engine. A diffusion flame is modeled in a simple cylindrical geometry and boundary conditions are defined. A specific solver which can model the turbulent diffusion flame by considering radiation in participating media is used to solve the problem....

We present a novel extension of the path tracing algorithm that is capable of treating highly scattering participating media in the presence of fluorescent structures. The extension is based on the formulation of the full radiative transfer equation when solved on a per-wavelength-basis, resulting in accurate model and unbiased algorithm for rendering highly scattering fluorescent participating...

The representation of participating media adds a very realistic effect in computer generated images. Unfortunately, they are especially difficult to render. Indeed, their contribution in the illumination of a scene is quite complex, depending on both light position and camera position. We present here a new algorithm that is able to render, in real-time, the single scattering induced by any par...
