The Influence of Crystallinity Degree on the Glycine Decomposition Induced by 1 MeV Proton Bombardment in Space Analog Conditions

TL;DR: In this article, the authors present an experimental study on the destruction of zwitterionic glycine crystals at room temperature by 1 MeV protons, in which the dependence of the destruction rates of the alpha-glycine and beta-gly cine crystals on bombardment fluence is investigated.

Optical modeling of nanostructured films for selective coatings

TL;DR: In this article, the authors developed computer model capabilities to predict the optical properties of such structures by solving the Maxwell and materials equations using the finite element method in three dimensions, which enables them to incorporate the full dispersion of metals, including their negative real part of permittivity.

A Rail-Temperature-Prediction Model Based on Machine Learning: Warning of Train-Speed Restrictions Using Weather Forecasting.

TL;DR: Wang et al. as discussed by the authors developed a reliable and highly accurate novel model that can predict rail temperature using a machine learning method, which used weather effect and solar effect features for predicting rail temperature over the entire network with high prediction performance.

Estimation of clear sky global solar radiation in Algeria

TL;DR: In this article, the performance of three models at three sites for estimating instantaneous clear-sky global solar radiation on a horizontal surface in Algeria was evaluated and the results in general exhibit that for global radiation, the daily correlation coefficient is higher than 0.99, whereas the mean absolute percentage error is less than 5%.

SSolar-GOA v1.0: a simple, fast, and accurate Spectral SOLAR radiative transfer model for clear skies

TL;DR: In this paper, a spectral radiative transfer model for the solar wavelength range under clear skies is proposed, which is based on the Ambartsumian method of adding layers in a one-dimensional medium to obtain the total transmittance of scattering.

Simple Solar Spectral Model for Direct and Diffuse Irradiance on Horizontal and Tilted Planes at the Earth's Surface for Cloudless Atmospheres

TL;DR: In this paper, a simple model for calculating direct normal and diffuse horizontal spectral solar irradiance for cloudless sky conditions was described. But the model was developed using rigorous radiative transfer codes and limited outdoor measurements.

- 01 Feb 1984 - 
TL;DR: In this paper, the authors presented a merging of the absolute integrals of the disk-center intensity for 20 A wide spectral bands and the ratios of mean to central intensity derived from recent observations of the center-to-limb variation of those bands (λ 6600 A).

Parameterized transmittance model for direct beam and circumsolar spectral irradiance

Christian A. Gueymard
- 01 Nov 2001 - 
TL;DR: In this article, an upgraded spectral radiation model called SMARTS2 (Simple Model of the Atmospheric Radiative Transfer of Sunshine) is introduced, based on spectral transmittance functions for the main extinction processes in the cloudless atmosphere: Rayleigh scattering, aerosol extinction, and absorption by ozone, uniformly mixed gases, water vapor, and nitrogen dioxide.
