Causality between stopped filtrations and some applications
(2021-11-21)In this paper we consider the concept of statistical causality in continuous time between filtrations associated with stopping times, which is based on Granger’s definition of causality. Especially, we consider a ... -
Tourism and sustainable development of rural settlements in protected areas - Example NP Кopaonik (Serbia)
(Elsevier Ltd., 2019-09-21)With the formulation of tourism development strategies for the social and economic development of an area, rural tourism moved to a more complex phase of development. Numerous empirical studies have shown that different ... -
Transmission performance of multimode W- type microstructured polymer optical fibers
(Optica Publishing Group (Formerly OSA), 2022-06-23)By solving the time-independent power flow equation (TI PFE), we study mode coupling in a multimode W-type microstructured polymer optical fiber (mPOF) with a solid-core. The multimode W-type mPOF is created by modifying ... -
Calculation of the mode coupling coefficient in step-index plastic optical fibers based on the far field measurements
(Frontiers, 2022-05-25)Using the power flow equation (PFE), this article investigates mode coupling in step-index (SI) multimode (MM) polymer optical fiber (POF). This equation’s coupling coefficient was initially fine-tuned so that it could ... -

Edukacija u korak sa savremenim istraživanjima radona
(Društvo fizičara Srbije, Beograd, 2018-10-07)Sistematska merenja koncentracije radona se najčešće izvode na slučajnim uzorcima stambenih objekata. Međutim, škole se mogu pokazati kao pogodniji izbor, jer su uniformno raspoređene po celoj teritoriji područja ili ... -
Generating function for the figurative numbers of regular polyhedron
(Hindawi, 2020-04-14)In this paper, we are going to demonstrate a method for determining the generating functions of tetrahedral, hexahedral, octahedral, dodecahedral, and icosahedral figurative numbers. The method is based on the differences ...
