Models of an asphaltene aggregate and a micelle of the petroleum colloid system
(CI and CEQ, 2000)
Using recent proposals for the hypothetical structure of an average asphaltene molecule and the results of determining the dimensions of asphaltene molecules and aggregates, a model of the asphaltene aggregate (nucleus) ...
Automated learning and control using speedup and neural networks
(CI and CEQ, 2000)
This paper studies complex dynamic neural network learning models. Backpropagation was used to train a neural network for dynamic simulation and control of a chemical stirred tank. The generalized delta rule algorithm was ...
Chemical plant fault diagnosis by neural networks / Dijagnostika kvara hemijskog postrojenja pomoću neuronskih mreža
(CI and CEQ, 2000)
An analysis of learning and generalization characteristics of neural networks for diagnosing process failures was presented. Various feedforward neural network topologies were tested and compared. The single fault assumption ...
New values of the polarity factor
(Serbian Chemical Society, 2000)
New values of the polarity factor χ for 96 substances are proposed. Estimation procedure is tested on the values of this factor from the original work of Halm and Stiel.44.
The electro-oxidation of the mixture of formaldehyde and 2-propanol on gold (100) and (111) single crystal planes in alkaline medium / Elektrooksidacija smeše formaldehida i 2-propanola na monokristalima zlata orijentacije (100) i (111) u alkalnoj sredini
(Serbian Chemical Society, 2000)
The effect of formaldehyde on the oxidation of 2-propanol and vice versa on gold single crystal planes (100 and 111) was studied. An activating effect in the reaction of the simultaneous oxidation of 2-propanol and ...
A new current line division concept for the determination of the current distribution in electrochemical cells. Part I. Theoretical background of the corner weakness effect in electroforming / Нов концепт поделе струјних линија за одржавање расподеле струје у електрохемијским ћелијама. Део I.Теоријске основе појаве "Corner weakness" у галванопластици
(Belgrade : Serbian Chemical Society, 2000)
A new approach to the determination of the current distribution in electrochemicalcells, the current line division concept, is introduced. The new concept, based on thebasic equations of electrics and electrochemical ...
Drying of suspension and pastes in fluidized bed of inert particles / Sušenje suspenzija i pasta u fluidizovanom sloju inertnog materijala
(Serbian Chemical Society, 2000)
A fluid bed dryer with inert particles was used for the drying of suspensions and pastes. The effects of the operating conditions on the dryer throughput and on the product quality were investigated. Experiments were ...
Reactivity of cyclohex-1-enylcarboxylic and 2-methylcyclohex-1-enylcarboxylic acids with diazodiphenylmethane in aprotic solvents / Reaktivnost cikloheks-1-enilkarbonske i 2-metilcikloheks-1-enilkarbonske kiseline sa diazodifenilmetanom u aprotičnim rastvaračima
(Serbian Chemical Society, Belgrade, 2000)
Rate constants for the reaction of diazodiphenylmethane with cyclohex-1-enylcarboxylic acid and 2-methylcyclohex-1-enylcarboxylic acid were determined in nine aprotic solvents, as well as in seven protic solvents, at 30 ...
Use of the SSF equations in the Kojima-Moon-Ochi thermodynamic consistency test of isothermal vapour-liquid equilibrium data
(Serbian Chemical Society, 2000)
The Kojima-Moon-Ochi (KMO) thermodynamic consistency test of vapour-liquid equilibrium (VLE) measurements for 32 isothermal data sets of binary systems of various complexity was applied using two fitting equations: the ...
Modification of the aluminum for making offset printing plates
(Serbian Chemical Society, 2000)
Aluminum as the base of offset printing plates should make good contact with wetting agents and the light sensitive layer and should be resistant to wear and cracking. In order to achieve this, the aluminum is roughened ...
