• Causality between stopped filtrations and some applications 

  Valjarević, Dragana; Petrović, Ljiljana (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) 

  Ristić, Dušan; Vukoičić, Danijela; Milinčić, Miroljub (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 

  Drljača, Branko; Savović, Svetislav; Kovačević, Milan; Simović, Ana; Kuzmanović, Ljubica; Djordjevich, Alexandar; Min, Rui (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 

  Savović, Svetislav; Djordjevich, Alexandar; Drljača, Branko; Simović, Ana; Min, Rui (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 ...

• Calculation of Bandwidth of Multimode Step-Index Polymer Photonic Crystal Fibers 

  Drljača, Branko; Savović, Svetislav; Kovačević, Milan; Simović, Ana; Kuzmanović, Ljubica; Djordjevich, Alexandar; Min, Rui (MDPI, 2021-12-01)

  By solving the time-dependent power flow equation, we present a novel approach for evaluating the bandwidth in a multimode step-index polymer photonic crystal fiber (SI PPCF) with a solid core. The bandwidth of such fiber ...
