The information explosion that has taken place over the past two decades has fundamentally changed the ways that companies do business. Today’s markets are driven more and more by information than by physical goods. Companies that cannot collect data and transform it into information are likely to experience difficulty competing in the near future (if they are not finding it difficult already)....
An experimental study on pressure evolution during closed vessel explosions of several gaseous fuel-air mixtures was performed, at various initial pressures within 0.3-1.2 bar and ambient initial temperature. Explosion pressures and explosion times are reported for methane-, n-pentane-, n-hexane-, propene-, butene-, butadiene-, cyclohexane- and benzene-air mixtures. The explosion pressures meas...
Fire and explosion accidents often occur in storage tanks leading to great economic loss and serious casualties during the working, operation and maintenance. This paper established a reduced-scale storage tank experimental system, and then the explosion characteristics of gasoline-air mixture in storage tank were studied. The experimental results show that several parameters (such as concentra...
Data is everywhere, notably in this information explosion era. Beyond the first-order summary of a sample by its average value or its median, the bell-shaped Gaussian (or normal) curve has long been observed in the histograms of many data samples since the early history of probability, statistics and related fields. The Gaussian distribution, known commonly under the name of Law of Frequency of...
Computing has been an enormous accelerator to science and industry alike and it has led to an information explosion in many different fields. The unprecedented volume of data acquired from sensors, derived by simulations and data analysis processes, accumulated in warehouses, and often shared on the Web, has given rise to a new field of research: provenance management. Provenance (also referred...
Because of the data deluge in scientific publication, finding relevant information is getting harder and harder for researchers and readers. Building an enhanced scientific search engine by taking semantic relations into account poses a great challenge. As a starting point, semantic relations between keywords from scientific articles could be extracted in order to classify articles. This might ...
The amount of data has grown exponentially in industry and internet, and we are facing a significant problem of information explosion. The challenge is not only to store and manage the vast volume of data (“big data”), but also to analyze and extract meaningful value from it. This paper analyzed the characters of the future network and the features of data generated by it. Furthermore, we studi...
In situ measurements of the sizes and concentrations of dust particles generated by the detonation of high explosives in clay soil near Leesville, La., sandy clay soil near Huntsville, Ala., and sandy soils near Orogrande, N.M. are reported. Measurements were generally made within 1 m of the surface (in one case 10 m) at distances ranging from 10 to approximately 50 m from the detonation point ...
Increasing the explosion power simultaneously reduction of explosive sensitivity caused to preparing new species of explosives. One of the considerable compounds in this field is dihydroxyl ammonium 5,5′-bistetrazole-1,1′-diolate (TKX-50). Evaluation of explosion properties of this material shows that its explosion efficiency is equal with CL-20. TKX-50 is compatible with most of th...
Growth of Rayleigh-Taylor (R-T) instabilities under the axisymmetric explosion are investigated by two-dimensional hydrodynamical calculations. The degree of the axisymmetric explosion and amplitude of the initial perturbation are varied parametrically to find the most favorable parameter for reproducing the observed line profile of heavy elements. It is found that spherical explosion can not p...
