Gamma Irradiation: Properties, Behavior and Applications
(Nova Science Publisher, 2021-08-11)
Gamma radiations are used for sterilization processes in medical devices, food industry as well as in nuclear power plants or aerospace. Gamma irradiation is a very convenient tool for the modification of polymeric materials. ...
Nano-silica-based urea-formaldehide composite with some derivates of coumarin as formaldehyde scavenger: hydrolitycal and thermal stability
(Springer Nature, 2021-01-25)
The hydrolytic stability of two nano-SiO2-based UF composites with derivates of coumarin (names as K-1 and K-2) was investigated. K-1 is 3-nitro-4-(p-tolylamino)-2H-chromen-2-one and K-2: 4-((3-nitro-2-oxo-2H-chromen-4-y ...
Influence of width of launch beam distribution and mode coupling on transmission characteristics of W-type plastic optical fibers
(IOP Science, 2021-07-16)
We show strong effects of width of the launch beam’s angular distribution on bandwidth and
mode coupling in W-type plastic optical fibers (POFs). In general, the broader this width, the
stronger the coupling and the lower ...
Influence of the Wavelength on the Bandwidth in W-Type Plastic Optical Fibers
(Springer Link, 2021-07-03)
We investigate the bandwidth and steady-state losses of multimode W-type plastic optical fibers solving the time-dependent power flow equation and show how the bandwidth in W-type plastic optical
fibers can be enhanced ...
A comparative study of two different finite difference methods for solving advection–diffusion reaction equation for modeling exponential traveling wave in heat and mass transfer processes
(Springer, 2021-10-26)
An unconditionally-positive finite difference (UPFD) and the standard explicit finite difference schemes are compared to the analytical solution of the advection–diffusion reaction equation which describes the exponential ...
Method for investigation of mode coupling in multimode step-index silica photonic crystal fibers
(Elsevier, 2021-07-30)
We propose a new method for investigation the state of mode coupling in a multimode step-index
silica photonic crystal fiber (SI SPCF) with a solid-core by solving the time-independent power
flow equation. For various ...
Wavelength dependent transmission in W-type plastic optical fibers with graded index core distribution
(Elsevier, 2021-08-08)
This paper investigates the wavelength dependence of the equilibrium mode distribution (EMD)
and steady state distribution (SSD) in W-type plastic optical fibers (POFs) with graded index (GI)
core distribution for ...
Power flow in multimode step-index plastic photonic crystal fibers
(Elsevier, 2021-08-21)
We investigate the state of mode coupling in a multimode step-index plastic photonic crystal fiber
(SI PPCF) with a solid-core by solving the time-independent power flow equation. For various
arrangements of air-holes, ...
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 ...
