Electron acceleration in solar flares: theory of spectral evolution [PDF]
Astronomy & Astrophysics, 2006 Context: Stochastic acceleration is thought to be a key mechanism in the energization of solar flare electrons. Aims: We study whether stochastic acceleration can reproduce the observed soft-hard-soft evolution of the spectral features of the hard X-ray emitted by suprathermal electron.

RE-ACCELERATION MODEL FOR RADIO RELICS WITH SPECTRAL CURVATURE [PDF]
The Astrophysical Journal, 2016 ABSTRACT Most of the observed features of radio gischt relics, such as spectral steepening across the relic width and a power-law-like integrated spectrum, can be adequately explained by a diffusive shock acceleration (DSA) model in which relativistic electrons are (re-)accelerated at shock waves induced in the intracluster medium ...

Estimation of seismic spectral acceleration in Peninsular India
Journal of Earth System Science, 2007 Peninsular India (PI), which lies south of 24°N latitude, has experienced several devastating earthquakes in the past. However, very few strong motion records are available for developing attenuation relations for ground acceleration, required by engineers to arrive at rational design response spectra for construction sites and cities in PI. Based on a

Probabilistic seismic hazard assessment of the historical peninsula of Istanbul [PDF]
Natural Hazards and Earth System Sciences, 2012 In order to design buildings that are resistant to earthquakes, first it is necessary to determine the parameters of ground motion. In this study, the earthquake seismic hazard analysis of the Old City Districts of Istanbul (Fatih and Eminonu) was ...

Buildings, 2023 There are very few results in the literature on spectral content of seismic ground displacement; nonetheless, these results are singular as most of the spectral content is limited to a very narrow low frequency band, contrary to ground acceleration ...
