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 ...
Specific properties of recycled aggregate concrete production technology / Specifičnosti tehnologije spravljanja betona na bazi recikliranog agregata
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2009)
This state-of-the-art paper deals with the differences in production technology of concrete made with recycled aggregate. The properties of recycled aggregate, as a component for new concrete production, are being analyzed ...
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 ...
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 ...
Univalency and convolution results associated with confluent hypergeometric functions
(Houston Journal of Mathematics, 2009)
Given the confluent hypergeometric functions Φ(a; c; z), we
place conditions on a and c to guarantee that zΦ(a; c; z) will be in two sub-
classes of univalent functions. In addition, we obtain conditions to obtain
some ...
Column Buckling Investigation of Plane Frames
(Serbian Society of Mechanics, 2009)
This paper deals with elastic stability analysis of the plane frame structures. The main aim is to investigate the accuracy of related parts of European and domestic codes for steel and concrete structures. Numerical ...
Train-induced vibrations: a case study
(13th International Symposium of MASE, Ohrid, Macedonia, 2009)
The paper is discussing a train-induced vibration analysis related to the new railway station “Belgrade-Center” in Prokop. The station is not jet built, but above the station area of approximately 400 x 100 m a huge RC ...
Long-term behavior of precast concrete girder with cast in place deck and diaphragm
(Department of Civil Engineering - Faculty of Tecnical Science, Novi Sad, 2009)
Composite precast-cast in place bridge girders made continuous for live load are very
popular solution for bridges of small to medium spans. In domain of service state of stresses,
material nonlinearity of concrete ...
About planar sections of a type of egg curve based conoid
(Novi Sad: Faculty of Sciences, University of Novi Sad - Department of Mathematics and Informatics, 2009)
Starting from a type of conoid which is based on a cubic egg curve obtained by Hügelschäffer’s construction, it is considered a possible occurrence of related type of conoid, which would include conic curve as a part of ...
