Conic Section of a Type of Egg Curve Based Conoid
(Belgrade: Faculty of Architecture in Belgrade; Serbian Society for Geometry and Graphics (SUGIG), 2010)
A cubic egg curve obtained by Hügelschäffer’s construction,
can be spatially interpreted as a plane section of a type of a conoid
set through a specially chosen 4-th order intersecting curve of two
quadrics: right ...
Forming the Cupolae With Concave Polyhedral Surfaces by Corrugating a Fourfold Strip of Equilateral Triangles
(Belgrade: Faculty of Architecture in Belgrade; Serbian Society for Geometry and Graphics (SUGIG), 2010)
The cupolae with concave polyhedral surfaces consist of: two regular
polygons, n-gone and 2n-gone in parallel planes, interconnected by an
envelope constituted of series of equilateral triangles. The paper
describes ...
Seminary Paper as an Additional Task in Teaching Descriptive Geometry
(Belgrade: Faculty of Architecture in Belgrade; Serbian Society for Geometry and Graphics (SUGIG), 2010)
As a result of introducing Bologna process in education, classes
of Descriptive geometry were reduced. In order to acquire such a
complex matter as Descriptive geometry, it was necessary to provide
an additional task ...
Recycled concrete as aggregate for structural concrete production
(MDPI AG, 2010)
A comparative analysis of the experimental results of the properties of fresh and hardened concrete with different replacement ratios of natural with recycled coarse aggregate is presented in the paper. Recycled aggregate ...
Possibility of application of old concrete as a new kind of aggregate in modern construction / Mogućnosti primene starog betona kao nove vrste agregata u savremenom građevinarstvu
(Inženjersko društvo za koroziju, Beograd, 2010)
Characteristic of the 20th century, in terms of civil engineering, is intensive construction without taking care about preservation of the natural resources and the impact of buildings on the environment in all stages of ...

(Savez inženjera i tehničara Srbije, Beograd, 2010)
This paper describes measurements and shows the results of the first GPS campaign taken in Serbia, realized by Military Geographical Institute from Belgrade in July 1990, within its Experimental geodetic network. As a ...
Municipal wastewater treatment in republic of Serbia: Present state and the perspectives / Prečišćavanje gradskih otpadnih voda u Republici Srbiji - stanje i perspektive
(Savez građevinskih inženjera Srbije, Beograd, 2010)
This paper presents an overview of municipal wastewater and sludge treatment methods. Procedure for determination of input wastewater loads has been described, as well as requirements that should be fulfilled to establish ...
Constructing the Egg Curves Using the Golden Ratio of Pentagon
(Belgrade: Faculty of Architecture in Belgrade; Serbian Society for Geometry and Graphics (SUGIG), 2010)
In the paper it is considered a construction of an egg curve
obtained by continual joining of the circular arcs with three different
centers. These three centers form sharp or flat triangles of the
pentagon (sharp and ...
Numerical simulation of the flow field in the vicinity of an intake structure / Numerička simulacija strujnog polja u blizini vodozahvata
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2010)
This paper deals with the analysis of the flow field in the vicinity of an intake structure. It is shown that flow and psamological characteristics can be determined successfully by 2D and 3D numerical models. Determining ...
Measurement uncertainty: Concept and procedural steps for quantification / Merna nesigurnost - pojam i proceduralni koraci pri kvantifikaciji
(Srpsko društvo za puteve VIA-VITA, Beograd, 2010)
The paper presents the procedure for estimation of measurement uncertainty, which is one of basic requirements of standard SRPS ISO/IEC 17025, applied in accredited laboratories for testing and calibrations. The concept ...
