Harmonization of new wind turbine rotor blades development process: A review
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
In this paper the harmonization of new wind turbine rotor blades development is given as well as the analysis of behavior by verification testing for a wind turbine rotor blade of composite materials. The design, fabrication, ...
Possibilities to identify engine combustion model parameters by analysis of the instantaneous crankshaft angular speed
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
In this paper, novel method for obtaining information about combustion process in individual cylinders of a multi-cylinder spark ignition engine based on instantaneous crankshaft angular velocity is presented. The method ...
Error bounds of the Micchelli-Sharma quadrature formula for analytic functions
(Elsevier Science Bv, Amsterdam, 2014)
Micchelli and Sharma constructed in their paper [On a problem of Turan: multiple node Gaussian quadrature, Rend. Mat. 3 (1983) 529-552] a quadrature formula for the Fourier-Chebyshev coefficients, which has the highest ...
Diagnostics of bucket wheel excavator discharge boom dynamic performance and its reconstruction
(Polish Academy of Sciences Branch Lublin, 2014)
The paper focuses on an investigation into the possible causes of the bad dynamic performance of bucket wheel excavator C7OOS (BWE) discharge boom in the Kolubara opencast mine, Serbia. A discharge boom load carrying ...
Modeling with Regression Analysis and Artificial Neural Networks the Resistance and Trim of Series 50 Experiments with V-Bottom Motor Boats
(Soc Naval Architects Marine Engineers, Jersey City, 2014)
Mathematical representations for the resistance, trim, and wetted length of the Experimental Model Basin Series 50 have been developed using conventional regression analysis techniques as well as artificial neural networks. ...
Mechanical characterization of anisotropic elasto-plastic materials by indentation curves only
(Kluwer Academic Publishers, 2014)
Anisotropy, usually orthotropy, arises in structural materials, particularly metals, due to production processes like laminations and concerns primarily parameters which govern the plastic behavior. Identification of such ...
Aerodinamičke karakteristike vozova velikih brzina pod dejstvom bočnih vetrova - numerička analiza koristeći nestacionarni RANS metod / Aerodynamic characteristics of high speed train under turbulent cross winds: A numerical investigation using unsteady-RANS method
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2014)
Usled trenda povećanja brzina i smanjenja mase modernih vozova velikih brzina neophodno je razmatrati dejstvo jakih bočnih vetrova na njihovu aerodinamiku. Jaki bočni vetrovi mogu uticati na stabilnost ovih vozova usled ...
Modelling of thermoset matrix composite curing process
(Trans Tech Publications Ltd, Durnten-Zurich, 2014)
Autoclave curing is a common practice to manufacture high temperature thermoset matrix composites in order to improve the mechanical properties of the final product. The cycle design i.e. the definition and optimization ...
On the extension of the erdos-mordell type inequalities
(Element, Zagreb, 2014)
We discuss the extension of inequality R-A >= c/a r(b) + b/a r(c) to the plane of triangle Delta ABC. Based on the obtained extension, in regard to all three vertices of the triangle, we get the extension of Erdos-Mordell ...
Analysis of transient ash pneumatic conveying over long distance and prediction of transport capacity
(Elsevier Science Bv, Amsterdam, 2014)
Pneumatic conveying of the lignite ash from blow tanks to a nearly 600 m distant silo at the 620 MWe thermal power plant is analyzed based on pressure measurements along the telescoping transport pipeline. Transient character ...
