Abstract Elastomeric material is used as blast-resistant structure because of its good mechanical properties.A series underwater near-field explosive tests at different standoff distances were conducted to investigate the anti-explosion performance steel structures covered with rubber and polyurea coatings. The experimental results demonstrated that both could enhance blast resistance test plat...

This paper presents the electrical conductivity data of copper along gas branch binodal curve in warm dense matter (WDM) regime as a function mass density and temperature. All are obtained using underwater wire explosion technique, which vaporized cools during period current dwell after explodes. Mass temperature measured by fast imaging optical spectroscopy, respectively. Combining these with ...

An inspection of signal processing approach in order to estimate underwater network cardinalities is conducted in this research. A matter of key prominence for underwater network is its cardinality estimation as the number of active cardinalities varies several times due to numerous natural and artificial reasons due to harsh underwater circumstances. So, a proper estimation technique is mandat...

Underwater robotics is currently a growing field. To be able to autonomously find and collect objects on the land and in the air is a complicated problem, which is only compounded within the underwater setting. Different techniques have been developed over the years to attempt to solve this problem, many of which involve the use of expensive sensors. This paper explores a method to find the dep...

The interaction of multiple bubbles is a complex physical problem. A simplified case studied theoretically with bubble located at the center circular cluster. All in cluster are equally spaced and own same initial conditions as central bubble. unified theory for dynamics (Zhang et al. arXiv:2301.13698) applied to model between To account effect propagation time pressure waves, emission source w...

background: fire and explosion hazards are extremely important in processing units. this study was performed to identify the risk centers, the potential damage caused by fire and explosion, and the days of production cessation in the processing company. materials and methods: the present qualitative case study was conducted using dow’s index in 2015. the fire and explosion hazard index and leve...
