Measurements and analysis of electron transport coefficients obtained by a pulsed Townsend technique
(IOP Publishing Ltd, Bristol, 2010)
A review of a wide range of electron swarm studies in several pure gases and gas mixtures is given. These studies include the determination of the cross section set for electrons in C(2)H(2)F(2) (R134a) based on recent ...
Inhibitory Effect of Cerium Salts of Lower Carboxylic Acids on Al-Zn-Mg-Cu Alloy in NaCl Solution
(Electrochemical Soc Inc, Pennington, 2021)
The corrosion behavior of AA7049 aluminum alloy in NaCl solution in the presence of environmentally-friendly corrosion inhibitors (Ce-chloride, Ce-formate, Ce-acetate, and Ce-propionate) was analyzed. The chemical composition ...
Surface characterisation of PLLA polymer in HAp/PLLA biocomposite material by means of nanoindentation and artificial neural networks
(Taylor & Francis Ltd, Abingdon, 2010)
In this paper, the mechanical properties of polymer matrix phase (modulus of elasticity, yield stress and work hardening rate) have been determined using combined methods such as nanoindentation, finite element modelling ...
Investigation of causes of fan shaft failure
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Energy efficiency of thermal power plants depends on the vital plant elements' reliability levels. In order to preserve high level of energy efficiency, the vital elements' operational capability is continually monitored ...
Reconfigurable robotic machining system controlled and programmed in a machine tool manner
(Springer London Ltd, London, 2011)
Industrial robots represent a promising cost-effective and flexible alternative for some machining applications. This paper describes the concept of reconfigurable robot multi-axis machining systems for machining the complex ...
Automatic feature recognition using artificial neural networks to integrate design and manufacturing: Review of automatic feature recognition systems
(Cambridge Univ Press, New York, 2011)
Feature technology is considered an essential tool for integrating design and manufacturing. Automatic feature recognition (AFR) has provided the greatest contribution to fully automated computer-aided process planning ...
Extension of Lightning Corona Sheath Model during Return Stroke
(Ieee-Inst Electrical Electronics Engineers Inc, Piscataway, 2011)
A generalized lightning traveling current source return stroke model has been used to examine the characteristics of the lightning channel corona sheath. A model of lightning channel consisting of a charged corona sheath ...
Calculated and experimental analysis of cause of the appearance of cracks in the running bogie frame of diesel multiple units of Serbian railways
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
In this paper an analysis of possible causes of crack occurrence on reconstructed diesel multiple units (DMU) exploited on sideline in Serbia was performed. Analyzed DMU were designed in the sixties of the last century in ...
Vibration and stability of a heavy and heated vertical circular plate
(World Scientific Publ Co Pte Ltd, Singapore, 2010)
This paper is concerned with the vibration and stability of a standing, heavy, and circular plate when heated. This investigation also deals with the plate being exposed to inertial forces due to uniform acceleration. The ...
The effects of dynamic load on behaviour of welded joint a-387 gr. 11 alloyed steel
(Croatian Metallurgical Society, 2013)
The in-service behaviour of alloyed steel A-387 Gr. 11 Class 1, for pressure vessels, used for high temperature applications, depends on the properties of its welded joint, with parent metal (BM), heat-affected-zone (HAZ) ...
