Understanding speech in the presence of background noise is one of the major problems for hearing-impaired persons. Although most digital hearing aids currently make use of advanced digital signal processing and multiple microphones to achieve noise reduction [1], the majority of hearing aid users still reports a significant reduction in speech understanding in noisy environments. Whereas open ...

Fungicides are the most common agents used in postharvest treatment of fruit and are the most effective against blue mould, primarily caused by Penicillium expansum. Alternatively, blue mould can be treated with antagonistic microorganisms naturally occurring on fruit, such as the bacterium Gluconobacter oxydans. The aim of this study was to establish the antifungal potential of the G. oxydans ...

Primljeno (Received): 2011-11-07 Prihvaćeno (Accepted): 2012-03-15 Original scientific paper Abstract: Pressure die casting is the method used for forcing molten metal into mould cavities under high pressure and at high speed (10 100 m.s). Pressure die casting is a highly productive method of casting parts with low dimensions tolerance and high surface quality. From the point of view of product...

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 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...

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...
