the risks of fire and explosion in oil and gas industry need to be managed. the objectives of the present study were to assess the risk of fire and explosion in iso-max unit of tehran oil refinery using dow’s fire and explosion index and to study the influences of the controlling methods. the latest version of dow fire and explosion index guideline was applied to calculate the fire and explosio...

the current manuscript presents the validation of smoothed particle hydrodynamics (sph) techniques for wave generation by underwater explosion, utilizing the so-called dualsphysics numerical model. this numerical method is used to analyze generated waves which are initiated by man-made or natural explosions below free surface level of sea. in spite of the modeling limitations (e.g. absence of o...

Motivated by recent models involving off-centre ignition of type Ia supernova explosions, we undertake three-dimensional time-dependent radiation transport simulations to investigate the range of bolometric light curve properties that could be observed from supernovae in which there is a lop-sided distribution of the products from nuclear burning. We consider both a grid of artificial toy model...

What happens when machines become more intelligent than humans? One view is that this event will be followed by an explosion to ever-greater levels of intelligence, as each generation of machines creates more intelligent machines in turn. This intelligence explosion is now often known as the “singularity”. The basic argument here was set out by the statistician I. J. Good in his 1965 article “S...

The information explosion has led to problems and possibilities in many areas of society, including that of law enforcement. In comparing individual criminal investigations on similarity, we seize one of the opportunities of the information surplus to determine what crimes may or may not have been committed by the same group of individuals. For this purpose we introduce a new distance measure t...

-The Coulomb explosion process of N20 in an intense laser-field (5 PW/cm 2) has been investigated by the high-resolution time-of-flight (TOF) spectroscopy. Six two-body explosion pathways involving the NO +, NO 2§ N2 § molecular ions have been securely identified from the momentum-scaled TOF spectra of the fragment ions. Assuming a linear geometry, three-body explosion pathways were investigate...

Abstract There are many varieties of new developed energetic materials with different capabilities shock wave pressure action. In order to effectively evaluate the explosive damage power diverse and make evaluation model universal, TNT is used as basic material, action established in this paper based on nonlinear fitting method. Explosion tests charge quantities carried out under same test cond...

The aim of this study was to elaborate identification method of crew overload as a result of trinitrotoluene charge explosion under the military wheeled vehicle. During the study, an experimental military ground research was carried out. The aim of this research was to verify the mine blast resistance of the prototype wheeled vehicle according to STANG 4569 as well as the anti-explosive seat. W...

Abstract Limited initiation energy or external stimulation may cause incomplete detonation in a warhead. At present, there is no quantitative method to characterize the release of warhead charge for such as explosion and deflagration. We propose based on average fragment quality released by charge. The theoretical study shows that after inversely proportional initial velocity. relationship betw...
