Data quality assessment is a key factor in data-intensive domains. The data deluge is aggravated by an increasing need for interoperability and cooperation across groups and organizations. New alternatives must be found to select the data that best satisfy users’ needs in a given context. This paper presents a strategy to provide information to support the evaluation of the quality of data sets...

'The economic statistics that the government issues every week should come with a warning sticker: User beware. In the midst of the greatest information explosion in history, the government is pumping out a stream of statistics that are nothing but myths and misinformation.' Michael J. Mandel, "The Real Truth about the Economy: Are Government Statistics so much Pulp Fiction? Take a Look," Busin...

This paper examines the paperclip apocalypse concern for artificial general intelligence. This arises when a superintelligent AI with a simple goal (ie., producing paperclips) accumulates power so that all resources are devoted towards that goal and are unavailable for any other use. Conditions are provided under which a paper apocalypse can arise but the model also shows that, under certain ar...

In the age of information explosion, e-learning recommender systems (ELRSs) have emerged as the most essential tool to deliver personalized learning resources to learners. Due to enormous amount of information on the web, learner faces problem in searching right information. ELRSs deal with the problem of information overload effectively and provide recommendations by taking into consideration ...

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...

A week marked by deadly hospital fires and a mass asphyxiation of covid-19 patients has highlighted the risks inherent to that inevitable accompaniment respiratory pandemic—vastly increased oxygen use. A total 82 people were left dead 110 injured from fire on 24 April in Baghdad, Iraq, which began with an explosion caused “a fault storage cylinders,” sources told Agence France-Presse. The was...

Abstract In severe cases of SARS-CoV-2 infection, death occurs as a result hypo-oxygenation peripheral tissues. The lung, severely damaged, can not ensure the transfer oxygen to blood. It is necessary increase alveolar concentration by supplementation, with or without mechanical ventilation. relatively poor outcomes are related fact that entire chain transport mitochondria compromised. capacity...
