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 ...
Use of Husimi function in time frequency signal analysis / Primena Husimijeve funkcije u vremensko-frekvencijskoj analizi signala
(Savez inženjera i tehničara Srbije, Beograd, 2013)
Husimi function originated in phase space formulation of quantum mechanics. This function appears naturally whenever simultaneous measurement of coordinate and impulse with maximal accuracy allowed by the Heisenberg ...
Vibrations measurement using wireless sensor network / Merenje vibracija mrežom bežičnih senzora
(Savez inženjera i tehničara Srbije, Beograd, 2012)
Laboratory prototype of a wireless sensor network (WSN) for vibrations measurements on buildings was developed. The system is comprised of sensor devices (nodes) each having main processor board, accelerometer board, ...
Integer points enumerator of hypergraphic polytopes
(Mathematical Institute of the Serbian Academy of Sciences and Arts, 2021)
For a hypergraphic polytope there is a weighted quasisymmetric
function which enumerates positive integer points in its normal fan
and determines its f −polynomial. This quasisymmetric function
invariant of hypergraphs ...
Hermitian Toeplicz determinants fr the class S of univalent functions
(National Academy of Sciences of the Republic of Armenia, 2021)
Introducing a new method, we give sharp estimates
of the Hermitian Toeplitz determinants of third order for the
class S of functions univalent in the unit disc. The new approach
is also illustrated on some subclasses ...
Interaction of lasers of various types with alloys based on Ni and Ti / Interakcija različitih tipova lasera sa legurama baziranim na niklu i titanijumu
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2008)
Commonly implemented nickel and titanium alloys are nowadays alloyed with many new elements. Obtained in this way, new Ti-alloys are of great practical significance in aircraft industry, while Ni-alloys are important in ...
Trajektorije fotona i kvantona kao aktuelna istraživačka tema
(Nastava fizike : zbornik radova sa Republičkog seminara o nastavi fizike, 2017)
Damage monitoring of composite laminates by means of intensity based fiberoptic sensors / Praćenje oštećenja kompozitnih laminata pomoću fiberoptičkih senzora intenzitetnog tipa
(Institut za ispitivanje materijala, Beograd, 2005)
The paper deals with the research in applying optical fibres (OF) as intensity-based sensors in real-time damage detection of laminar composite materials. For experimental purposes, thermoplastic laminar composite materials ...
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 ...
Rail defects head checking on the Serbian railways
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2014)
The rail defects due to rolling contact fatigue represent serious safety hazard for rail traffic all around the world. That hazard is more distinct on railways without adequate maintenance strategy, with the increase of ...
