Coherent Beam Splitting by a Thin Grating
(Polish Academy of Sciences, 2009)
The wide use of beam splitters in quantum interferometry, attosecond metrology, modern quantum information processing, foundations of quantum mechanics, has been based on coherence of beams emerging from a beam splitter. ...
Starlike and close-to-convexfunctions defined by differential inequalities
(Elsevier, 2009)
We present new sufficient conditions for an analytic function to be close-to-convex and
starlike, respectively. These conditions are easy to apply and can be used to obtain functions
in these classes.
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 ...
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 ...
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 ...

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 ...
Laser Interaction with Material - Theory, Experiments and Discrepancies
(Polish Academy of Sciences, 2009)
The experimental treatment of chosen material with laser beams, starting from continuous wave up to fs pulses, produces the necessity to find the common and sophisticated theoretical approaches to interaction modeling. For ...
The Influence of Various Morphologic and Hemodynamic Carotid Plaque Characteristics on Neurological Events Onset and Deaths
(Thescientificworldjournal, 2009)
A group of 72 patients with 111 asymptomatic carotid stenoses (ACS), mean age 65.42 +/- 9.21, and a group of 36 patients with 58 symptomatic carotid stenoses (SCS), mean age 67.63 +/- 8.79, were analyzed prospectively ...
Time-Frequency Analysis of Nonstationary Optical Signals Using Husimi Type Function
(Polish Academy of Sciences, 2009)
Time-frequency analysis is important to identify the localized information of a non-stationary signal in the time and frequency domains simultaneously. There are few different time-frequency analysis methods available with ...
