It is explained that knowledge grows in a mould created by scholars concerned and the meaning of shown to have different features than famous paradigm introduced Kuhn 1962. The present science be European (Western) scientists, whereas other moulds nations or civilisations do exist but fossilised stagnated as they are overlaid enclosed restricted colonial mould. Knowledge given name ethnoknowled...

The demand of highest possible effectiveness is put on all production processes, while the highest quality is demanded from products. These requirements are particularly justifi ed in the steel industry, due to high cost of technical equipment assembly and production cost. In such conditions continuous processes are of signifi cant meaning, since they facilitate maximum utilization of productio...

The phenomenon of Sick Building Syndrome (SBS), Building Related Illness (BRI) and some other indoor related diseases have been attributed to mould and fungi exposure in the indoor environment. Despite the growing concern over mould and fungi infestations on building materials, little has been reported in the literature on the development of an objective tool and criteria for measuring and char...

The quality of castings in a green sand mould is influenced significantly by its properties, such as green compression strength, permeability, mould hardness, and others, which depend on input parameters. The relationships of these properties with the input parameters, like sand grain size and shape, binder, water, etc. are complex in nature. In the neural network based forward mapping, mould p...

PURPOSE Temperature increase of 5.5 ℃ can cause damage or necrosis of the pulp. Increasing temperature can be caused not only by mechanical factors, e.g. grinding, but also by exothermic polymerization reactions of resin materials. The aim of this study was to evaluate influences of the form material on the intrapulpal temperature during the polymerization of different self-curing resin materia...

A variety of parts in microsystems technology are manufactured by injection moulding of polymeric materials. In Particular the high cooling velocity affects negatively the process and the resulting part properties. The scope of this paper is to investigate the influence on the reachable flow length in injection moulding of different polymeric materials. The results indicate that the mould tempe...

The manufacturing of moulds and dies is achieved through expensive and complicated manufacturing processes. There is a need in the mould and die tool industry for technologically advanced systems/machinery that will be able to facilitate re-conditioning of moulds and dies at moderate costs and within short period of time. The re-conditioning process requires highly dextrous equipment, with high...

In this paper we bring together two Operations Research techniques, Cutting and Packing Optimisation (CPO) and Simulation, and present a multi-methodology approach for analysing the trade-offs between loading efficiency and various important practical considerations in relation to the cargo such as its stability, fragility, or possible cross-contamination between different types of items over t...

We studied the pattern transfer fidelity of nanoimprint lithography (NIL) by patterning sub-micron MESFET gates on six-inch wafers. The critical dimensions (CD) of the gate patterns on the mould, imprinted in resist, as well as after oxygen reactive ion etching (RIE) and metal lift-off were measured, separately, using an ultrahigh-resolution scanning electron microscope. Comparison of the measu...

The problem motivating the current work is a mould filling during casting process. The aim of our analysis is to provide a simple experimental model simulating the main flow characteristics accompanying such process. Hence, the hot fluid is supplied under high pressure into an inclined box. Fluid flows inside the box between two cold isothermal walls, passing obstacles simulating internal compl...
