A trigonometric orthogonality with respect to a nonnegative Borel measure
(Univerzitet u Nišu - Prirodno-matematički fakultet - Departmant za matematiku i informatiku, Niš, 2012)
In this paper we consider trigonometric polynomials of semi-integer degree orthogonal with respect to a linear functional, defined by a nonnegative Borel measure. By using a suitable vector form we consider the corresponding ...
Comparison of methodologies for identification of process parameters affecting geometric deviations in plastic injection molding of housing using Taguchi method
(Kaunas Univ Technol, Kaunas, 2012)
This paper examines parameters that could influence geometric part deviation (shrinkage and warpage) of the Housing (Cycoloy, PC/ABS, Grade C2800) produced by plastic injection molding. Five parameters (temperature of ...
Experimental and Simulation Testing of Flight Spin Stability for Small Caliber Cannon Projectile
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2012)
The basic aim of this paper is to consider correlations of stability flight criteria, derived as the relations of aerodynamic coefficients and derivatives, on the model of a small caliber cannon spin stabilized projectile. ...
A Model for Shaped Charge Warhead Design
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2012)
A model for shaped charge warhead design was developed. The model is incorporated in the computer code - CUMUL. The code includes detonation wave profile estimation, liner collapse, arrival of collapsed liner to the ...
Computation Method in Failure Analysis of Mechanically Fastened Joints at Layered Composites
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2012)
This paper considers a computation method in failure analysis of layered composites containing pin-loaded holes. The investigation is focused on developing a reliable computation procedure to analyze initial failure load ...
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 ...
Effect of microstructure on tensile properties of austenite-ferrite welded joint
(Faculty of Metallurgy, 2015)
Complex microstructure of austenite-ferrite welded joint has been investigated, focused on its influence on Focal tensile properties. Tensile properties (yield strength and hardening coefficient) have been evaluated by ...
Numerical simulation of non-conventional liquid fuels feeding in a bubbling fluidized bed combustor
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2013)
The paper deals with the development of mathematical models for detailed simulation of lateral jet penetration into the fluidized bed, primarily from the aspect of feeding of gaseous and liquid fuels into fluidized bed ...
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 ...
Comparative analyses of built environment exposures relevant to health of greenhouse gas emissions reduction strategies in Serbia
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Paper presents comparative analysis of residential indoor air pollutant concentration change over future specified time horizon, implementing building physical and thermal retrofit measures, thus creating pollution mitigation ...
