In this research, the analysis of ramming factor, wall thickness, and quantity additives powder have been considered on permeability mould which is used to make flange coupling cast. The data has collected from sand making industry using L27 orthogonal array. It was revealed that maximum obtained lowest thin minimum mixing additives. number increased significantly proper allowability gas cavity...

appropriate distance for the sources to be placed from the skin surface. The trajectories which the sources would take were then drawn, with uniform separation, on this surface. The mould was completed by extending the surface further and then subtracting the trajectories. The complete STL file was then sent to the printer for fabrication by the Stratasys Objet500 Connex1 printer, and printed u...

Using a mould for thermoforming produced by fused filament fabrication implies several limitations, such as thermal damage due to the low conductivity properties of plastic material. For cooling mould, many different approaches and influencing factors can be considered. This paper identifies those factors, based on statistical DOE, adequate experiments have been conducted analyze influence proc...

Many studies have considered the effects of suspension properties on the dewatering process but fewhave focused on ore properties. Thus, the present work studied the effects of ore properties (density,particle size, mineralogy) on the dewatering process based on lab and pilot experiments. A hydrocyclonewas used to prepare the required samples for the experiments. To study the effects of mineral...

In buildings growing conditions for mould fungi can occur and cause fungus infestation. The possible danger for the occupants of dwellings lies in the production and spreading of pathogens (disease causing agents). Therefore, consequent measures have to be taken to avoid health dangers that result from mould fungi in buildings. A strategy has to be set up that focuses on the growth conditions f...

Multi-faceted experiments were conducted to measure the properties of several mould slags needed for the fundamental characterization of heat transfer and friction in the interfacial gap between the shell and mould during the continuous casting (CC) of steel. A novel apparatus was used to measure the friction coefficient between solidified mould flux and copper at elevated temperatures. The mea...

In laboratory experiments we demonstrate that protoplasmic tubes of acellular slime mould Physarum polycephalum show current versus voltage profiles consistent with memristive systems. This result complements previous findings on memristive properties of other living systems (human skin and blood and leaves) and contributes to development of self-growing bioelectronic circuits.

in this paper, a three-dimensional finite element model has been developed to simulate the laser-tig hybrid welding (hlaw) of stainless steel 1.4418 with thickness of 4 mm. transient temperature profile and dimensions of the fusion zone and heat affected zone (haz) during welding process are calculatedusing finite element method (fem) and were solved in the abaqus/standard software.the heat sou...
