Criteria for univalent functions in the unit disc
(SpringerBirkhäuser Verlag, 2013)
Injectivity and starlikeness of sections of a class of univalent functions
(Pennsylvania State University, University Park, 2013)
The maximum number of P-vertices of some nonsingular double star matrices
(Discrete Mathematics, 2013)
In this short note, we construct a nonsingular matrix A whose graph is a double star of order
n > 4 with n − 2 P-vertices. This example leads to a positive answer, for n > 6, to a last
open question proposed recently by ...
Geometry of twisted surfaces applied on horizontal communications in architecture / Geometrija spiralnih površi primenjena na horizontalne komunikacije u arhitekturi
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2013)
Contemporary technologies and materials continuously challenge structural designers, as well as architects, to achieve unique applications of various geometric surfaces. Twisted structures are actual and numerous in building ...
Removal of the false targets in the issues of spatial triangulation by projective geometry methods
(Structural Mechanics of Engineering Constructions and Buildings, 2013)
This paper deals with an issue of determination of the spatial coordinates within confined
area in general terms. Mobile air space control stations were set and related to the system of spatial triangulation. As a result ...
On the properties of the concave antiprisms of second sort / O osobinama konkavnih antiprizmi druge vrste
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2013)
The paper examines geometrical, static and dynamic properties of the polyhedral structures obtained by folding and creasing the two-rowed segment of equilateral triangular net. Bases of these concave polyhedra are regular, ...
Mathematical Principles and Optimal Design Solutions to Compensation for the Pendulum Temperature Dilatation
(Acta Polytechnica Hungarica, 2013)
The paper analyzes the effects of pendulum temperature dilatation on the timepiece running and accounts for the basic mathematical principles that neutralization of these detrimental effects are based upon. Both preliminary ...
A computer verification of a conjecture about the Erdös-Mordell curve
(2013 21st Telecommunications Forum Telfor, TELFOR 2013 - Proceedings of Papers, 2013)
In this paper we consider Erdös-Mordell inequality and its extension in the plane of triangle to the Erdös-Mordell curve. Algebraic equation of this curve is derived, and using modern computer tools in mathematics, we ...
Unordered multiplicity lists of wide double paths
(DMFA Slovenije, 2013)
Recently, Kim and Shader analyzed the multiplicities of the eigenvalues of a Φ-binary tree. We carry this discussion forward extending their results to a larger family of trees, namely, the wide double path, a tree consisting ...
