Statistical causality and purely discontinuous local martingales
(Taylor and Francis, 2021-07-21)
The statistical concept of causality in continuous time between
filtered probability spaces considered in this paper is based on
Granger’s definition of causality. The given concept of causality can
be connected to the ...
Statistical causality and measurable separability of σ-algebras
(Science direct, 2021-07-21)
In this paper we consider a concept of statistical causality, based on Granger’s definition
of causality and analyze the relationships between given causality and the concept
of measurable separability of σ-algebras. The ...
Theoretical Investigation of the Influence of Wavelength on the Bandwidth in Multimode W-Type Plastic Optical Fibers with Graded-Index Core Distribution
(MDPI, 2021-11-17)
The bandwidth of multimode W-type plastic optical fibers (POFs) with graded-index (GI) core distribution is investigated by solving the time-dependent power flow equation. The multimode W-type GI POF is designed from a ...
Calculation of Bandwidth of Multimode Step-Index Polymer Photonic Crystal Fibers
(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 ...
Power flow in multimode W-type plastic optical fibers with graded index core distribution
(Elsevier, 2021-06-11)
A method is proposed for investigation of transmission along a multimode W-type (doubly clad) plastic optical fiber (POF) with graded index (GI) distribution of the core. The multimode W-type GI POF is designed from a ...
Investigation of bandwidth in multimode graded-index plastic optical fibers
(Optica Publishing Group, 2021-09-13)
A new method is proposed for investigating the bandwidth in multimode graded-index
plastic optical fibers (GI POFs). By numerically solving the time-dependent power flow equation,
bandwidth is reported for a varied launch ...
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 ...
Synthesis and characterization of pH-sensitive Saccharide modified polyurethane hydrogels – Effect of polyol, crosslinker and acid chain extender
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2021-07-10)
Biodegradable polyurethanes can be the basis for drug delivery systems that
are sensitive to external changes. pH-sensitive polyurethanes (PUs) have been
used successfully as intravaginal rings and specific drug delivery ...
