Electrohydraulic thrust vector control of twin rocket engines with position feedback via angular transducers
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
The thrust vector control (TVC) of rocket engines is used when the aerodynamic surfaces are inadequate to control vehicles or when a greater agility may be required of a missile. Traditionally, in all spacecraft to date ...
Correlation of microstructures and tribological properties of ferrous coatings deposited by atmospheric plasma spraying on Al-Si cast alloy substrate
(Springer, New York, 2009)
The microstructure and tribological properties of ferrous coatings applicable to cylinder bores were investigated in this study. Two kinds of ferrous powders were sprayed on Al-Si cast alloy (EN AlSi10Mg) substrate by ...

Measurement and analysis of angular velocity variations of twelve-cylinder diesel engine crankshaft
(Academic Press Ltd- Elsevier Science Ltd, London, 2011)
This paper presents the procedures for measuring and analyzing the angular velocity variation of twelve-cylinder diesel engine crankshaft on its free end and on the power-output end. In addition, the paper deals with ...
Effect of Excess Air Ratio and Temperature on NOx Emission from Grate Combustion of Biomass in the Staged Air Combustion Scenario
(Amer Chemical Soc, Washington, 2011)
The combustion of biomass, in this case demolition wood, has been investigated in a grate combustion multifuel reactor. In this work a temperature range of 850-1000 degrees C is applied both for staged air combustion and ...
Asymptotic behavior of orthogonal trigonometric polynomials of semi-integer degree
(Elsevier Science Inc, New York, 2012)
Orthogonal systems of trigonometric polynomials of semi-integer degree with respect to a weight function w(x) on (0, 2 pi) have been considered firstly by Turetzkii [A.H. Turetzkii, On quadrature formulae that are exact ...
Spectroscopic research on infrared emittance of coal ash deposits
(Elsevier Science Inc, New York, 2009)
This paper deals with thermal radiation characteristics of ash deposits on a pulverized coal combustion boiler of an electric power plant. Normal emittance spectra in the near to medium infrared (2.5-25 mu m) region and ...
A computer code for the prediction of mill gases and hot air distribution between burners' sections at the utility boiler
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
One of the main tasks during the design or simulation and analyses of the utility steam boiler operation is the prediction of a distribution of mill gases and hot air flow rates between burners' sections. These are the ...
Prediction of thermal transients in district heating systems
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
A prediction of thermal transients in district heating systems is important in order to adjust in an energy efficient manner the loads of heat power plants and pump stations with dynamic consumption needs during changes ...
The contraction principle for set valued mappings on a metric space with a graph
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Let (X, d) be a metric space and F : X hooked right arrow X be a set valued mapping. We obtain sufficient conditions for the existence of a fixed point of the mapping F in the metric space X endowed with a graph G such ...
