Landscape functioning assessment based on radiation temperature distribution

Circumstellar grains: radiation pressure and temperature distribution

The ratioβ of the radiation pressure force to the gravitational attraction is calculated for circumstellar grains. Eleven stars of various spectral type are considered and their spectral flux compiled from available data sometimes supplemented by appropriate models. The materials composing the grains are a silicate (obsidian), organic materials (ice tholin, poly-HCN), graphite and glassy carbon...

Landscape assessment of high-rise buildings: A method based on 3DGIS, BIM and AHP

In this paper, we propose a quantitative indicator for measuring and ranking real estate from the perspective of the surrounding landscape by integrating the building information model (BIM) and the three-dimensional geospatial information system (3DGIS) based on the AHP method. The landscape is one of the qualitative variables which it's measuring and quantifying is a complex task. In previous...

On Temperature Radiation

In this work we compare two blackbody interpretations, those of G. Kirchhoff and M. Planck. We separate the problem of interpreting the blackbody spectrum from that of determining the mechanical equivalent of radiation. Then we propose that, if we set aside characterization of the blackbody, electromagnetism suffices to analyze spectral distribution and leads to interpreting it as determined by...

The Electron Stopper Layer Effect on Long-Wavelength VCSEL with AsSb-Based DBR Temperature Distribution

In this study, we have theoretically investigated the effect of electron stopper layer on internal temperature distribution of high performance vertical cavity surface-emitting laser emitting at 1305 nm. Simulation software PICS3D, which self-consistently combines the 3D simulation of carrier transport, self-heating, gain computation and wave-guiding, was used. Simulation results show that chan...
