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 ...
Triangular proportional scheme and concept of the two Serbian medieval churches
(Springer Verlag, 2018)
Serbian medieval architectural heritage is notable for its sacred architecture including numerous Christian Orthodox churches built at the territory of former Raška state during the period from the 12th to the 14th centuries. ...
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 ...
Damage detection in laminar thermoplastic composite materials by means of embedded optical fibers / Detektovanje oštećenja u laminarnim termoplastičnim kompozitnim materijalima korišćenjem ugrađenih optičkih vlakana
(Savez hemijskih inženjera, Beograd, 2006)
This paper investigates the possibility of applying optical fibers as sensors for investigating low energy impact damage in laminar thermoplastic composite materials, in real time. Impact toughness testing by a Charpy ...
Twenty-four position tilt test for accelerometer cross-axial sensitivity compensation / Kompensacija poperečnoj čuvstvitel'nosti MËMS akselerometrov s pomošč'ju testirovanija statičnogo ugla naklona, provedennogo v 24-eh pozicijah
(Univerzitet odbrane u Beogradu - Institut za naučne informacije, Beograd, 2017)
Cross-axial or transverse sensitivity of an accelerometer can be compensated by digital processing of the output signal. To perform this, it is necessary to determine coefficients that describe a sensor's response to ...
A generalization of nil-clean rings
(Miskolc Mathematical Notes, 2018)
The conditions that allow an element of an associative, unital, not necessarily commutative ring R, to be represented as a sum of (commuting) idempotents and one nilpotent element are analyzed. Some applications to group ...
The total graph of a module
(Društvo matematičara Srbije, Beograd, 2011)
A generalization of the total graph of a ring is presented. Various properties are proved and some relations to the total graph of a ring as well as to the zero-divisor graph are established.
