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.

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.

The Low-High-Low Trend of Type III Radio Burst Starting Frequencies and Solar Flare Hard X-rays [PDF]

, 2014
Using simultaneous X-ray and radio observations from solar flares, we investigate the link between the type III radio burst starting frequency and hard X-ray spectral index.

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 ...

Twinkling pulsar wind nebulae in the synchrotron cut-off regime and the gamma-ray flares in the Crab Nebula

, 2011
Synchrotron radiation of ultra-relativistic particles accelerated in a pulsar wind nebula may dominate its spectrum up to gamma-ray energies. Because of the short cooling time of the gamma-ray emitting electrons, the gamma-ray emission zone is in the ...

An Overview of the Seismic Elastic Response Spectra and Their Application According to Mexican, U.S., and International Building Codes

Applied Sciences, 2022
The design of earthquake-resistant structures by applying traditional or performance-based seismic analysis methods involves two large variables: the seismic risk of the area and the physical characteristics of the structure.

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.

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.

A Suzaku X-Ray Study of the Particle Acceleration Processes in the Relativistic Jet of Blazar Mrk 421

, 2010
We report on the findings of a 364 ksec observation of the BL LAC object Mrk 421 with the X-ray observatory Suzaku. The analysis in this paper uses fluxes and hardness ratios in the broad energy range from 0.5 keV to 30 keV.
