Structural, mechanical and tribological properties of A356 aluminium alloy reinforced with Al2O3, SiC and SiC plus graphite particles
(Elsevier Science Sa, Lausanne, 2010)
Particulate composites with A356 aluminium alloy as a matrix were produced by compocasting process using ceramic particles (Al2O3, SiC) and graphite particles. The matrix alloy and the composites were thermally processed ...
A fuzzy model for an increase in locomotive traction force
(Vilnius Gediminas Tech Univ, Vilnius, 2010)
This paper deals with the process of traction force realization described by a suitable mechanical model and is pointed to the adhesion phenomenon as a physical one, i.e. is a suitable factor that the value of traction ...
Energy-saving estimation model for hypermarket HVAC systems applications
(Elsevier Science Sa, Lausanne, 2011)
Energy saving estimation model (ESEM) use normal distribution (Gaussian) probability theory to predict potential savings for previously determined system improvements. Those improvements are low/high cost investments based ...
Bifurcation control of a generalized VDP system driven by color-noise excitation via FOPID controller
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Fractional-order PID (FOPID) controller, as the results of recent development of fractional calculus, is becoming wide-used in many deterministic dynamical systems, but not in stochastic dynamical systems. This paper ...
A numerical investigation of the refrigerant maldistribution from a header towards parallel channels in an evaporator of automotive air conditioning system
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Evaporators in automotive air conditioning are designed as compact heat exchangers with the aim to cool outside air for the widest possible range of weather conditions. Under low operating loads a non-uniformity of the ...
Groundwater heat pump selection for high temperature heating retrofit
(Elsevier Science Sa, Lausanne, 2012)
Retrofitting of fossil fuel powered hot water radiator heating systems of the existing buildings by groundwater heat pumps can provide significant energy savings followed by economic and environmental benefits. The paper ...
Investigation on thermal radiation spectra of coal ash deposits
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
This paper deals with thermal radiation properties of ash deposits on a pulverized coal boiler of an electric power plant. Normal emittance spectra in the 2.5-25 mu m interval, and total normal emittance, were measured on ...
Modeling the temperature in coal char particle during fluidized bed combustion
(Elsevier Sci Ltd, Oxford, 2008)
The temperatures of a coal char particle in hot bubbling fluidized bed (FB) were analyzed by a model of combustion. The unsteady model includes phenomena of heat and mass transfer through a porous char particle, as well ...
Heat transfer rate of direct-contact condensation on baffle trays
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The paper deals with the experimentally obtained results of the direct-contact condensation of steam in contact with water in cascade column. Baffle trays were used to obtain contact between water and steam in DN 300 column ...
Common fixed point under contractive condition of Ciric's type on cone metric type spaces
(Springer International Publishing Ag, Cham, 2012)
The purpose of this article is to generalize common fixed point theorems under contractive condition of A dagger iriA double dagger's type on a cone metric type space. We give basic facts about cone metric type spaces, and ...
