This paper reports a study into the effect of winding type on stressed-strained state wall steel cylindrical tank filled with oil to predefined level. The shapes free oscillations in and natural frequencies structure were analyzed. Stress was estimated basis finite-element simulation deformation three-dimensional structural model under influence distributed pressure inner surface stresses outer...

this study was designed to determine the effects of dietary replacement of fish oil with canola oil ongrowth performance, feed efficiency of body and economic indices of experimental diets of juvenilecommon carp (cyprinus carpio). during the experiment 270 juvenile fish with an average initialweight of 16.24 ± 0.10g were randomly distributed in 18 well aerated cylindrical polyethylene tanks(15 ...

Abstract Adsorption phenomena are encountered in several engineering applications. One of its uses is the storage and transport gas form adsorption tanks. The exothermic nature process decreases capacity presenting an impetus to understand thermal characteristics process. Studies using mixtures phase change materials adsorbents tanks demonstrate potential improvements They also show that distri...

Let A be a set of trivariate irreducible integral polynomials and let D be an A-invariant cylindrical algebraic decomposition (cad) of three-dimensional space. This paper presents a new algorithm for determining the interstack adjacencies in D over a given non-nullifying (for A) 0-cell, 1-cell adjacency in the cad D 0 of the plane induced by D. We show that this new adjacency algorithm for thre...

A multi-level mathematical model was used to estimate the stressed-strained state of a cylindrical reservoir with defect in wall shape form dent; concentration stresses zone studied. The proper choice verified; it has been shown that engineering assessment tank variable thickness could employ ratios for shell constant thickness. spread values is 2?10 %. This indicates model, as well fact possib...

This system aims to design and develop a prototype of an automatic for cleaning domestic cylindrical water tanks. The proposed includes simple mechanism with centrifugal force. Household tanks are supposed provide safe cleaning, gardening, cooking, drinking. majority the time coming into tank comes dust dirt particles. Over time, sludge or sediment may build up, contaminate cause illnesses in h...
