Assessment of Degradation of Sulfonylurea Herbicides in Water by Chlorine Dioxide
The degradation of two sulfonylurea herbicides, nicosulfuron and thifensulfuron methyl in water by chlorine dioxide, was studied for the first time in this paper. In order to examine the optimal parameters for degradation ...
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 ...
Wavelength dependence of equilibrium mode distribution and steady state distribution in W-type plastic-clad silica fibers
(Elsevier, 2019-11-27)
Wavelength dependence of equilibrium mode distribution (EMD) and steady state distribution (SSD) in W-type
plastic-clad silica fibers (PCSFs) is investigated in this paper for parametrically varied width of the fiber’s ...
Controlling the bandwidth of W-type plastic-clad silica optical fibers
(IOP Publishing, 2019-06-27)
A new design of a multimode plastic-clad silica optical fiber that takes the characteristic
W-shaped index profile is proposed. The bandwidth and steady-state loss are determined
for such a W-type plastic-clad silica ...
Theoretical investigation of bandwidth of multimode step-index silica photonic crystal fibers
(MDPI, 2022-03-23)
Solving the time-dependent power flow equation (PFE) provides a useful method to study
the transmission bandwidth of step-index silica photonic crystal fibers (SI SPCFs). The transmission
bandwidth of these kinds of ...
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, ...
Theoretical investigation of the capacity of space division multiplexing with step-index air-clad silica optical fibers
(MDPI, 2022-02-23)
We studied the effect of mode coupling on the space division multiplexing (SDM) capabilities of multimode step-index (SI) air-clad silica optical fibers by numerically solving the power
flow equation. Mode coupling ...
Flexibility of curves on a single-sheet hyperboloid
Hyperbolic towers are towers in the shape of a single-sheet hyperboloid, and they are interesting in architecture. In this paper, we deal with the infinitesimal bending of a curve on a hyperboloid of one sheet; that is, we ...
