Weighting Factor Selection of the Ensemble Model for Improving Forecast Accuracy of Photovoltaic Generating Resources

open access: yesEnergies, 2019
Among renewable energy sources, solar power is rapidly growing as a major power source for future power systems. However, solar power has uncertainty due to the effects of weather factors, and if the penetration rate of solar power in the future ...

Improved global fit to Non-Standard neutrino Interactions using COHERENT energy and timing data

open access: yesJournal of High Energy Physics, 2020
We perform a global fit to neutrino oscillation and coherent neutrino-nucleus scattering data, using both timing and energy information from the COHERENT experiment. The results are used to set model-independent bounds on four-fermion effective operators

Development of a local empirical model of ionospheric total electron content (TEC) and its application for studying solar-ionospheric effects

open access: yesScientific Reports, 2021
Regular and irregular variations in total electron content (TEC) are one of the most significant observables in ionospheric studies. During the solar cycle 24, the variability of ionosphere is studied using global positioning system derived TEC at a mid ...

New Weinberg operator for neutrino mass and its seesaw origin

open access: yesJournal of High Energy Physics, 2019
We consider a new Weinberg operator for neutrino mass of the form H u H ˜ d L i L j $$ {H}_u{\tilde{H}}_d{L}_i{L}_j $$ involving two different Higgs doublets H u , H d with opposite hypercharge, where H ˜ s d $$ \tilde{H}{s}_d $$ is the charge conjugated

Sensitivity of direct detection experiments to neutrino magnetic dipole moments

open access: yesJournal of High Energy Physics, 2020
With large active volume sizes dark matter direct detection experiments are sensitive to solar neutrino fluxes. Nuclear recoil signals are induced by 8B neutrinos, while electron recoils are mainly generated by the pp flux. Measurements of both processes

A study of the influence of the base thickness on photoelectric parameters of silicon solar cells with the new TCAD algorithms [PDF]

open access: yesНаучно-технический вестник информационных технологий, механики и оптики, 2021
The Sentaurus TCAD software package is widely used in the modeling of semiconductor optoelectronic devices. The main part of simulating solar elements is creating a correct geometric model.

Analysis of Temperature and Thermal Stress for a Solar Power Tower Molten Salt Receiver under Multi-Source Uncertainties

open access: yesApplied Sciences, 2022
Although uncertainties such as solar radiation and material properties are generally involved in the solar receiver design process, current studies in the solar receiver field are based on deterministic models and do not incorporate these uncertainties ...

Long-Term Cosmic Ray Variability and the CME-Index

open access: yesAdvances in Astronomy, 2012
The cosmic ray modulation in relation to solar activity indices and heliospheric parameters during the period January 1996–October 2011, covering the solar cycle 23 and the ascending phase of solar cycle 24, is studied.

Analytical Methods for Mathematical Modeling of Dye-Sensitized Solar Cells (DSSCs) Performance for Different Local Natural Dye Photosensitizers

open access: yesComputational and Experimental Research in Materials and Renewable Energy, 2022
In this paper, a new approach to generate the modified ideal diode factor of solar cells was developed which overcomes the problem of assuming its value a constant.

Searches for atmospheric long-lived particles

open access: yesJournal of High Energy Physics, 2020
Long-lived particles are predicted in extensions of the Standard Model that involve relatively light but very weakly interacting sectors. In this paper we consider the possibility that some of these particles are produced in atmospheric cosmic ray ...
