Optical Instrument Survival In A Major Earthquake [PDF]

, 1980
Many organizations presently are evaluating the potential loss to plant, equipment and production capability in event of a major earthquake in their area. Often it is found that equipment can be protected at a fraction of the replacement cost.

Dynamic response and damage character of road embankment under strong earthquake

International Journal of Distributed Sensor Networks, 2018
Dynamic response of road embankment under strong earthquake was explored by site investigation, shaking table tests, and discrete element method simulations, which shows that the distribution of responded accelerations strongly depends on the amplitude ...

Gamma ray measurements of the 1991 November 15 solar flare [PDF]

, 2000
The 1991 November 15 X1.5 flare was a well observed solar event. Comprehensive data from ground-based observatories and spacecraft provide the basis for a contextual interpretation of gamma-ray spectra from the Compton Gamma Ray Observatory (CGRO).

Integration of local soil effect into the assessment of seismic hazard at the Kharga Oasis, Western Desert, Egypt

Scientific African, 2021
The effect of local soil is integrated into the assessment of seismic hazard at the Kharga Oasis, Western Desert, Egypt. The work is done by adopting the probabilistic approach of seismic hazard assessment and the site response analysis.

Accelerating an adiabatic process by nonlinear sweeping

, 2012
We investigate the acceleration of an adiabatic process with the same survival probability of the ground state by sweeping a parameter nonlinearly, fast in the wide gap region and slow in the narrow gap region, as contrast to the usual linear sweeping ...
