Analysing the Performance and Working Parameters of A CNG Compressor Prototype Designed As A Household Type
(Gazi Univ, 2016)Nowadays, the natural gas has been used as energy resource to decrease environment pollution and support fuel economy in the vehicles, which are used in commercial load and passenger transport. Using natural gas has become ... -
Analysis of energy flow in thick plate structures
(Pergamon-Elsevier Science Ltd, 1997)At sufficiently high frequencies: where the structural wavelength is much smaller than the thickness of the structure, the rotational inertia and transverse shear effects become increasingly important. In this study the ... -
Analysis of free and forced vibration of a cracked cantilever beam
(Elsevier Sci Ltd, 2007)Structures are weakened by cracks. When the crack size increases in course of time, the structure becomes weaker than its previous condition. Finally, the structure may breakdown due to a minute crack. Therefore, crack ... -
Analysis of orthotropic plate structures by the direct-dynamic stiffness method
(Pergamon-Elsevier Science Ltd, 1995)… -
Analytical and finite element comparisons of stress intensity factors of composite materials
(Elsevier Sci Ltd, 2000)In this paper, a comparative study regarding the determination of stress intensity factors (SIF) for non-standard thin composite plates is presented. Carbon-epoxy composite plates are considered for the study. Unnotched ... -
Application of ANN to explore the potential use of natural ventilation in buildings in Turkey
(Pergamon-Elsevier Science Ltd, 2007)Indoor natural ventilation provides both the circulation of clear air and the decrease of indoor temperature, especially, during hot summer days. In addition to openings, building dimensions and position play a significant ... -
Application of the dynamic stiffness technique to the in-plane vibrations of plate structures
(Pergamon-Elsevier Science Ltd, 1996)In this study the dynamic stiffness technique, which yields ''exact'' results for a certain class of plate structure, is extended to include in-plane vibrations. Using the equations of motion and edge tractions the stiffness ... -
Artificial neural network analysis of heat pumps using refrigerant mixtures
(Pergamon-Elsevier Science Ltd, 2004)In this study, we have investigated the performance of a vapor compression heat pump with different ratios of R12/R22 refrigerant mixtures using artificial neural networks (ANN). Experimental studies were completed to ... -
Artificial neural network application to the friction-stir welding of aluminum plates
(Elsevier Sci Ltd, 2007)An artificial neural network (ANN) model was developed for the analysis and simulation of the correlation between the friction stir welding (FSW) parameters of aluminium (Al) plates and mechanical properties. The input ... -
An assessment of the effects of in-plane vibrations on the energy flow between coupled plates
(Academic Press Ltd, 1996)The majority of the studies of energy transmission in plate-type structures are based on the assumption that the main component of the energy transfer is due to flexural waves, and the contribution of in-plane waves may ... -
Brush seal temperature distribution analysis
(Asme, 2006)Brush seals are designed to survive transient rotor rubs. Inherent brush seal flexibility reduces frictional heat generation. However high surface speeds combined with thin rotor sections may result in local hot spots. ... -
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 ... -
Clamp fixation to prevent unfolding of a suture knot decreases tensile strength of polypropylene sutures
(Springer, 2012)Purpose Although sutures evolved in last decade and the product spectrum broadened largely, they can be still classified into two: monofilament and multifilament. Sutures are the mainstay of orthopedic procedures like ... -
A comparative study of lubricated friction and wear behaviour of Al-25Zn-3Cu-3Si bearing alloy
(Sage Publications Ltd, 2014)Lubricated friction and wear behaviour of Al-25Zn-3Cu-3Si alloy was investigated on a block-on-disc test machine in comparison with 60/40 brass and SAE 65 bronze. T6 heat treatment increased the hardness, strength and wear ... -
