The spectral evolution of impulsive solar X-ray flares. II.Comparison of observations with models
, 2005 We study the evolution of the spectral index and the normalization (flux) of the non-thermal component of the electron spectra observed by RHESSI during 24 solar hard X-ray flares.

Effects of Boundary Condition Models on the Seismic Responses of a Container Crane
Applied Sciences, 2019 In recent years, several large earthquakes have caused the collapse of container cranes, which have resulted in halting of freighting, and significantly affected the economy.

SCAR - Spectral Clustering Accelerated and Robustified
, 2022 Spectral clustering is one of the most advantageous clustering approaches. However, standard Spectral Clustering is sensitive to noisy input data and has a high runtime complexity. Tackling one of these problems often exacerbates the other. As real-world datasets are often large and compromised by noise, we need to improve both robustness and runtime ...

Vibration Analysis of 5-DOF Vehicle Model under Stochastic Road Surface Excitation
MATEC Web of Conferences, 2016 Considering human body vertical motion, vehicle body vertical motion, pitch movement and vertical jump of front and rear wheels, a five-degree-of-freedom vehicle model is established to study basic driving characteristics of the vehicle.

On the nonthermal X-ray emission in blazar jets [PDF]
, 1999 We consider particle acceleration to high energy via diffusive shock acceleration in a simple, self-consistent shock in jet model for blazars. Electrons are assumed to be accelerated at a shock front in relativistic jets and radiate synchrotron emission ...

Acceleration-induced spectral beats in strongly driven harmonic oscillators
Nature Communications, 2023 Abstract The harmonic modulation of coherent systems gives rise to a wealth of physical phenomena, e.g., the AC-Stark effect and Mollow triplets, with important implications for coherent control and frequency conversion.

First order Fermi acceleration driven by magnetic reconnection
, 2012 A box model is used to study first order Fermi acceleration driven by magnetic reconnection. It is shown, at least in this simple model, that the spectral index of the accelerated particles is related to the total compression in the same way as in ...

Site-Specific Earthquake Ground Motions for Seismic Design of Port Facilities in Indonesia
Applied Sciences, 2022 In Indonesia, infrastructure, such as port facilities, has been damaged by earthquakes. Therefore, evaluating rational earthquake ground motions (EGMs) for seismic design is necessary to mitigate earthquake disasters in the future.
