Retrofitting Low Carbon Aviation Fuels Processes From Natural Gas to Renewables Energy‐Based Systems
Greenhouse Gases: Science and Technology, EarlyView.ABSTRACT The aviation sector's dependence on high‐energy‐density fuels presents a challenge for decarbonization. This study evaluates the economic and environmental feasibility of retrofitting a gas‐to‐liquid (GTL) plant for low carbon aviation fuel (LCAF) production using solar electrification, an advanced reformer unit (CARGEN), and a hybrid ...

Turbulence, complexity, and solar flares [PDF]
Advances in Space Research, 2010 The issue of predicting solar flares is one of the most fundamental in physics, addressing issues of plasma physics, high-energy physics, and modelling of complex systems. It also poses societal consequences, with our ever-increasing need for accurate space weather forecasts.

FEATURES OF THE DEVELOPMENT OF A CIRCULAR SOLAR FLARE
Odessa Astronomical Publications, 2020 We present the results of the analysis of morphology and evolution of the circular solar flare using H-alpha images. H-alpha filtergrams were obtained with the Meudon spectroheliograph.

Global Properties of Solar Flares [PDF]
Space Science Reviews, 2011 This article broadly reviews our knowledge of solar flares. There is a particular focus on their global properties, as opposed to the microphysics such as that needed for magnetic reconnection or particle acceleration as such. Indeed solar flares will always remain in the domain of remote sensing, so we cannot observe the microscales directly and must ...

Triggering Process of the X1.0 Three-ribbon Flare in the Great Active Region NOAA 12192 [PDF]
, 2017 The solar magnetic field in a flare-producing active region (AR) is much more complicated than theoretical models, which assume a very simple magnetic field structure.

Climate and political effects on agriculture: Empirical evidence from SSA
International Studies of Economics, EarlyView.Abstract The most of Sub‐Saharan African (SSA) countries have been affected by climate change and food insecurity problems due to the reduction of production and productivity of cereal crops in the continent. The purpose of this research was to examine the short‐run and long‐run effects of climate change on agricultural productivity in 24 selected SSA ...

Solar flares: The impulsive phase [PDF]
Solar Physics, 1989 AbstractOnly during the previous solar cycle have systematic observations begun to be made with the sensitivity and time resolution, and the continuous coverage required to catch the impulsive phase and measure the rapid variations present in many wavelength ranges.

Temporal Variation of Flare Occurrence Rates via the Spot Evolution on the Sun and Solar-type Stars
The Astrophysical JournalThe spot evolution on the Sun and solar-type stars is important for understanding the nature of consequential flaring activity. This study statistically investigates the variance of flare occurrence rate through the time evolution of spots on the Sun and

Solar Flare Intensity Prediction With Machine Learning Models
Space Weather, 2020 We develop a mixed long short‐term memory (LSTM) regression model to predict the maximum solar flare intensity within a 24‐hr time window 0–24, 6–30, 12–36, and 24–48 hr ahead of time using 6, 12, 24, and 48 hr of data (predictors) for each Helioseismic ...
