Models of chemical reactors can be quite complex as they include information regarding the reactions, the transfer of species between phases, the transfer of energy, and the inlet and outlet flows. Furthermore, the effects of the various phenomena are quite intertwined and thus difficult to quantify from measured data. This paper proposes a mathematical transformation of the balance equations t...

ripening is one of the most important stages in production of cheese. in this research to comprehensive study of uf cheese ripening as the major industrial cheese that is produced in iran, mass transfer, heat transfer and changes in quality and sensory properties, simultaneously considered and a mathematical model was developed to describe them. thus, at first, lipolysis, proteolysis, texture a...

This paper has reported on the electrical and nonstructural of polymer-based materials in corporation NiO (Nickel oxide) in concentrations of 0.2%, 0.4% and 0.8% by weight of PVA (polyvinyl alcohol) polymer. Nanocrystallites phases and properties were characterized with using X-ray diffraction (XRD), Fourier transfer infrared radiation (FTIR),Energy distribution X-ray(EDX) techniques and X-Map ...

INTRODUCTION Automation is one of the main means for handling increasing complexity in systems. Indeed, automation makes it possible for designers to transfer the burden of operators to a system. Thus automation is having a strong impact on workload, team size and human error. However, together with this high potential, automation raises also complex issues at all the levels of the development ...

Most current conceptualisation of knowledge transfer emerges from the premise of occidental heritage. This paper examines the dialectical procedure, underpinning the unification of knowledge as an entity, and discusses dimensions of knowledge and knowledge transfer from the practitioner’s perspective. The study asks why, if knowledge is vital for business success and competitive advantage, the ...

Abstract: During solidification and casting in metallic molds, the heat flow is controlled by the thermal resistance at the casting-mold interface. Thus heat transfer coefficient at the metal- mold interface has a predominant effect on the rate of heat transfer. In some processes such as low pressure and die-casting, the effect of pressure on molten metal will affect the rate of heat transfer a...

X k=1 z 0k A0;k(z M)Mi01(z M): (41) This formula makes transparent exactly what happens in a recursive computation of the correlation functions. At every stage i, we have the Z-transform at points M 0i n of the appropriate function. In going to the (i + 1)st stage, the rst term Mi01(z M) ensures that values at the previous stage are retained at the even points, while the second term interpolate...
