In this paper,fluidity onset analysis in FG thick-walled spherical tanks under concurrent pressure loading and heat gradient has been presented. Designing thick-walled spherical tanks under pressure as tanks holding fluids under heat loads with high heat gradients require new approaches. Under high internal pressure and high temperature, the tank enters the plastic stage in a part of its thickn...

 The influence of five pure diets of isonitrogenous and isoenergic with different ratios of Clupeidae fish oil (F) and soybean oil (S) on growth, molting and survival of narrow-clawed crayfish, Astacus leptodactylus, was evaluated during an 8-weeks trial. As soybean oil replaced with fish oil in each treatment, gently. Test diets were inclusive F0/S100, F30/S70, F50/S50, F70/S30 and F100/S0 fis...

In this paper we propose a solution to a real-world time series regression problem: the prediction of fill levels of stormwater tanks. Our regression model is based on Support Vector Regression (SVR), but can easily be replaced with other data mining methods. The main intention of the work is to overcome frequently occuring problems in data mining by automatically tuning both preprocessing and ...

This study considers a cyclic scheduling of hoist movements in electroplating industry. Several jobs have to flow through a production line according to an ordered bath sequence. They firstly enter the line at a loading buffer. Then they will be soaked sequentially in a series of tanks containing specific chemical baths. Finally, they will leave the line at the unloading buffer. The processing ...

The proper management of oily sludge from petroleum products storage tanks is necessary because inappropriate methods for dredging of tanks may result in high costs and increased environmental pollution. The purpose of the current study is to rank the strategies outlined by strengths, weaknesses, opportunities and threats analysis using data envelopment analysis model, which provides enriched i...

The flow in stormwater tanks has a major impact on their treatment efficiency. A measurement method and an evaluation method was developed to identify unfavourable flow conditions in existing sedimentation tanks. The data base is provided by mobile, event-controlled measurements of tracerbased hydrographs. The analysis is based on transfer functions known in system theory. The model parameters ...

a large settling tank. There are five such tanks. They are connected with one another and a constant level is maintained in all. The capacity of each tank is 1.2 million gallons; the total capacity being 6 million gallons. The daily draw is about 2 million gallons. Hence theoretically the water settles for about 3 days before entering the Paterson filters. The engineer in charge, however, state...
