Experimental and finite element study of the thermal conductivity of alpha-SiAlON ceramics
(Wiley, 2007)
The thermal conductivity of monolithic Y-Sm/alpha-SiAlON was evaluated using experimental data and finite element analysis. The thermal diffusivities of Y, Y-Dy, and Y-Ce/alpha-SiAlON ceramics were also investigated ...
Computer aided modelling of flexible forming process
(Elsevier Science Sa, 2004)
Flexible forming enables the production of sheet metal parts with complex contours and bends by utilising a flexible medium, such as natural or synthetic rubber, as one half of a conventional die set. This study is concerned ...
Predictions of temperature distributions on layered metal plates using artificial neural networks
(Pergamon-Elsevier Science Ltd, 2006)
The temperature distribution influences the amount of energy needed to heat a body. The benefits of using multi-layered metal plates (NIMP) are due to the requirement of a regular temperature distribution on the opposite ...
Comparative study of mathematical and experimental analysis of spark ignition engine performance used ethanol-gasoline blend fuel
(Pergamon-Elsevier Science Ltd, 2007)
This study consists of two cases: (i) The experimental analysis: Ethanol obtained from biomass can be used as a fuel in spark ignition engines. As renewable energy source ethanol, due to the high octane number, low emissions ...
Calculation for the thermodynamic properties of an alternative refrigerant (R508b) using artificial neural network
(Pergamon-Elsevier Science Ltd, 2007)
This study proposes a alternative approach based on artificial neural networks (ANNs) to determine the thermodynamic properties - specific volume, enthalpy and entropy - of an alternative refrigerant (R508b) for both ...
Exergy analysis of an ejector-absorption heat transformer using artificial neural network approach
(Pergamon-Elsevier Science Ltd, 2007)
This paper proposes artificial neural networks (ANNs) technique as a new approach to determine the exergy losses of an ejector-absorption heat transformer (EAHT). Thermodynamic analysis of the EAHT is too complex due to ...
Use of artificial neural networks for mapping of solar potential in Turkey
(Elsevier Sci Ltd, 2004)
Turkey has sufficient solar radiation intensities and radiation durations for solar thermal applications since Turkey lies in a sunny belt, between 36degrees and 42degrees N latitudes. The yearly average solar-radiation ...
A computer simulation for estimating lower bound fracture strength of composites using Weibull distribution
(Elsevier Sci Ltd, 2004)
Estimating confidence lower bound for fracture strength of composites is a key concern in design and manufacture, and the Weibull distribution has been widely used for this purpose. Previous simulation-based studies presented ...
Investigating the potential use of natural ventilation in new building designs in Turkey
(Elsevier Science Sa, 2006)
The most economic air conditioning of living and working places can be achieved by natural ventilation if sufficient. This provides not only the circulation of clear air, but also the decrease of indoor temperature, ...
Vibration monitoring for defect diagnosis of rolling element bearings as a predictive maintenance tool: Comprehensive case studies
(Elsevier Sci Ltd, 2006)
Vibration monitoring and analysis in rotating machineries offer very important information about anamolies formed internal structure of the machinery. The information gained by vibration analysis enable to plan a maintenance ...
