The influence of the acid extract of peel of Cucurbita maxima (PCM) on the corrosion of mild steel in 1N H2SO4 was investigated by weight loss, polarization and impedance methods and SEM analysis. The inhibition efficiency increases with extract concentration and immersion period. Weight loss and corrosion rates of mild steel decreased as the concentration of inhibitor increased. The results sh...

In this work, we attempt a quantitative estimation of the type IV rupture stress for welds in ferritic power plant steels containing 9–12 wt. % chromium, using a neural network in a Bayesian framework. This article describes the methodology that was used in creating and evaluating the neural network model. The sensitivity of the rupture stress to the test conditions, the composition of the stee...

This paper reports on the development of algorithms for factory decisionmaking and scheduling systems. The particular decision-making and schedule coordination problem studied relates to the synchronisation of a series of events in the context of a production changeover in electric arc steel-making. The paper explores two distributed approaches to this co-ordination problem. The first is a simp...

Roller is a key component of milling machine in iron and steel industry, with the development of industrial wireless technology. The online predictive maintenance of the roller plays an important role in effective production. But the harsh working environment – spray of cooling liquid, moving, high temperature and heavy shelter – cause low quality of wireless communication and need high reliabi...

It was July 7, 1912, and Harry Houdini, ir the company of a bevy of dutiful report ers, was going to perform one of his greatest escapes, from a barge floating in the middle of the East River in New York. First he was shackled in leg irons two pairs of handcuffs, and elbow irons. Then he was crammed into a sturdy wooden crate, 40 inches x 22 inches x 24 inches, and the lid was nailed shut and r...

The association between cancer incidence and the residence near polluting facilities in an industrial area nearby Taranto has been investigated. Age, sex and occupational exposure were controlled as confounding variables in a case-control study (658 cases, 2092 controls). High risks were evidenced close to the steel mill (OR: 3.54), coke plant (OR: 4.80), mineral deposit (OR: 3.33) and shipbuil...

The present paper approaches the development and application of a Discrete Event Simulation (DES) model with a Multiple Criteria Decision Analysis (MCDA) tool for the simulation and sizing of a closed-loop maritime transportation system. This system is responsible for the supply of raw materials, especially iron ore, to a steel plant, and its sizing involves the analysis of the transportation f...
