Quality and Reliability of Safety Relief Valves
No full textThe leading particulates of safety relief valve testing facilities, judged by the ISPESL Italian Control Authorities as being suitable and reliable, were singled out. These facilities enabled a whole cycle of experimental tests to be conducted in free blowdown and variable back pressure conditions, which led to the evaluation of the leading performance characteristics of a new series of safety relief valves in accordance with real working conditions. The protective function of these devices justifies the interest in any possible further improvement of their performance, quality and reliability

No full textA new approach in the engineering project analysis: the aggregation game
No full textThe engineering project is a complex process developing through time as a series of elementary phenomena also conditioned by random external circumstances. A new approach in engineering project analysis is referred to in a model based on an elementary game. In this paper, in order to improve the comprehension of the suggested approach, an example of a game is illustrated

No full textA model based on artificial neural network for risk assessment to polycyclic aromatic hydrocarbons in workplace
No full textPolycyclic aromatic hydrocarbons (PAHs) are formed during incomplete combustion in different production processes; exposure to PAH-containing substances increases the risk of cancer in humans. The environmental monitoring used to assess human exposure to airborne PAHs during work, generally involves the employment of diagnostic methods derived from analytical chemistry, characterised by an elevated cost and the use of a "trial and error" approach. The aim of this study is to develop a decision support tool that, through the characteristic parameters of a workplace and using an artificial neural network, simulates the concentration of different species of pollutants (PAHs groups) statistically present in the environment. In this way it is possible to perform a preliminary risk assessment that, besides allowing an immediate perception of the level of risk to which workers are exposed, can undertake environmental monitoring analysis on the detection of a limited number of pollutant species, in order to reduce costs and increase the sustainability of the production syste
