Modeling of properties of fiber reinforced cement composites / Modeliranje svojstava mikroarmiranih cementnih kompozita
(Univerzitet u Nišu, Niš, 2008)
This paper presents the results of authors' laboratory testing of the influence of steel fibers as fiber reinforcement on the change of properties of cement composite mortar and concrete type materials. Mixtures adopted - ...
Coefficient characterization for certain classes of univalent functions
(Bulletin of the Belgian Mathematical Society - Simon Stevin, 2009)
Necessary and sufficient coefficient conditions are established for certain
classes of analytic functions to be univalent in the unit disk. In addition,
characterizations and convolution results are established for these ...
An application of Groebner bases to planarity of intersection of surfaces
(Univerzitet u Nišu - Prirodno-matematički fakultet - Departmant za matematiku i informatiku, Niš, 2009)
In this paper we use Groebner bases theory in order to determine planarity of intersections of two algebraic surfaces in R3. We specially considered plane sections of certain type of conoid which has a cubic egg curve as ...
Mechanical properties of recycled aggregate concrete / Mehaničke karakteristike betona na bazi recikliranog agregata
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2009)
For the purpose of the environmental preservation and sustainable development, production of concrete made of recycled concrete rubble (recycled aggregate concrete-RAC) become more often. Results of experimental investigations ...
Common right factor of skew polynomials / The Resultants of Non-Commutative Polynomials
(Matematički vesnik, 2008)
Let R = K[x; σ] be a skew polynomial ring over a division ring K. Necessary and sufficient condition under which common right factor of two skew polynomials exists is estab-lished. It is shown that the existence of common ...
Mathematical modelling of ecological processes in reservoirs of hydroenergetic systems / Modeliranje ekoloških procesa u akumulacijama hidroenergetskih sistema
(JP Elektroprivreda Srbije, Beograd, 2009)
Prediction of dynamic changes of water quality in lakes and reservoirs is very important from the aspects of planning and exploitation of hydroenergetic systems. That is the main reason for increasing development of ...
Microstructure and durability related properties of recycled aggregate concrete / Mikrostruktura i trajnost betona sa recikliranim agregatom
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2009)
Aspects of environmental safety, sustainable development, natural resources preservation and proper disposal of construction and demolition waste impose recycling as an important production technology of the construction ...
Moguće uštede primenom energetski efikasnih građevinskih materijala za omotače potkrovlјa
(Savez energetičara, 2008)
Zbog nedostatka stanova, zahvaljujući zakonskim rešenjima koja su to omogućavala, mnogi podstanari su svoje stambeno pitanje rešavali adaptacijom tavanskih prostora, ili nadziđivanjem postojećih zgrada. Nadziđivanja od ...
Polynomial Interpolation Problem for Skew Polynomials
(Applicable Analysis and Discrete Mathematics, 2007)
Let R = K[x;δ] be a skew polynomial ring over a division ring K. We introduce the notion of derivatives of skew polynomial at scalars. An analogous definition of derivatives of commutative polynomials from K[x] as a function ...
3D analysis of tunnel lining - rock mass interaction, I: Numerical modelling / 3D analiza interakcije tunelske obloge i stenske mase, I - numeričko modeliranje
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2004)
In the analysis of tunnel lining - rock mass interaction, it is essential to consider partial stress release at the tunnel face, i.e. deformation of the tunnel walling that occurs before the application of the lining. ...
