Functional simulator of 3-axis parallel kinematic milling machine
(Springer London Ltd, Artington, 2009)
Parallel kinematic machines (PKM) are research-and-development topic in many laboratories although many of them, unfortunately, have no PKM at all. Therefore, the use of low cost but functional simulator of a 3-Axis parallel ...
Development and application of crack parameters
(Springer, Dordrecht, 2009)
The development, definition and implementation of crack parameters (stress intensity factor, crack tip open displacement, J integral, filial stretch zone) are presented. They are now used for structural integrity and ...
Error estimates for Gaussian quadratures of analytic functions
(Elsevier Science Bv, Amsterdam, 2009)
For analytic functions the remainder term of Gaussian quadrature formula and its Kronrod extension can be represented as a contour integral with a complex kernel. We study these kernels on elliptic contours with foci at ...
Computer aided system for segmentation and visualization of microcalcifications in digital mammograms
(Via Medica, Gdansk, 2009)
Two methods for segmentation and visualization of microcalcifications in digital or digitized mammograms are described. First method is based on modern mathematical morphology, while the second one uses the multifractal ...
Određivanje propelernih i kombinatorskih karakteristika Kaplanove turbine agregata u HE 'Zvornik' u cilju povećanja njegove efikasnosti / Propeller and combinatory characteristics determination of Kaplan turbine in HPS 'Zvornik' with the aim of increasing its efficiency
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd i Društvo termičara Srbije, Beograd, 2009)
U radu su prikazani rezultati merenja i proračuna koji su urađeni na agregatu A3 u HE 'Zvornik', a u cilju određivanja propelernih i kombinatorskih karakteristika Kaplanove turbine. Specifična pažnja je posvećena određivanju ...
Design update, thermal and fluid dynamic analyses of the EU-HCPB TBM in vertical arrangement
(Elsevier Science Sa, Lausanne, 2009)
In the frame of the activities of the EU Breeder Blanket Programme and of the Test Blanket Working Group of ITER, the Helium Cooled Pebble Bed Test Blanket Module (HCPB TBM) is developed in Forschungszentrum Karlsruhe (FZK) ...
Cross sections and transport properties of negative ions in rare gases
(IOP Publishing Ltd, Bristol, 2009)
We have used a combination of a simple semi-analytic theory - Momentum Transfer Theory (MTT) and exact Monte Carlo (MC) simulations to develop momentum transfer cross sections of negative ions in collisions with noble gases ...
Dijagnostika tehničkih pokazatelja održavanja termoelektrane, deo II - određivanje pouzdanosti postrojenja u prvom približenju
(Visoka tehnička škola strukovnih studija, Beograd, 2009)
Pouzdanost i raspoloživost su osnovni tehnički pokazatelji kvaliteta eksploatacije u najširem smislu, a time i konkurentnosti termoenergetskog postrojenja u uslovima deregulisanog tržišta električnom energijom. Eksploataciona ...
Optical Biopsy Method for Breast Cancer Diagnosis Based on Artificial Neural Network Classification of Fluorescence Landscape Data
(Polish Acad Sciences Inst Physics, Warsaw, 2009)
Supervised self-organizing map, a type of artificial neural network, is applied for classification of human breast tissue samples utilizing data obtained from fluorescence landscape measurements. Female breast tissue samples ...
Influence of mechanical activation on the structure of ultrafine BaTiO3 powders
(Elsevier Science Sa, Lausanne, 2009)
The influence of mechanical activation in a planetary ball mill on the change of the structure of BaTiO3 powders has been investigated. The particle size distribution of the nonactivated and activated samples was measured ...
