One of the factors which limits the transmission capacity of the fiber optics communication channel is the material dispersion. Exact analytical study of the material dispersion is often complex and involves calculating the derivatives of the refractive index of the core. These calculations are too cumbersome to do, especially for high-order derivatives. So material dispersion has only been stu...
The optical rotatory dispersion of five individual specimens of Bence-Jones proteins was investigated, including the far ultraviolet spectral zone. The Mo5tt constants (bo) were determined, and either low positive or low negative values were found. The rotatory dispersion curves of all specimens had flat negative minima at 220 to 235 rnp and positive maxima at 204 to 212 rnp. Denaturation with ...
An analytical solution for the transient two-dimensional atmospheric pollutant dispersion problem is presented. The approach used in this problem utilizes the double GITT (Generalized Integral Transform Technique), the Laplace Transform and the matrix diagonalization. Furthermore, mathematical filters are used due to the existence of non-homogeneous boundary conditions. The results we obtained ...
A [0, m]-space is a linear space with the following property: For any point-line pair (x, G) there are at most m lines through x which are coplanar with G and which have no point in common with G. For every [0, m]-space (M, 90l) we define an order o r d M in a natural way. For dimM~>3 and o r d M ~ > 3 m + 2 , every [0, m]-space (M, 991) can be embedded in a projective space (P, £) with dim P =...
Whtle many people report interruptions from problem-solking to be beneficial for the creative process (‘incubation’). experimental demonstration of the phenomenon has been difficult. Factors that might lead to incubation effects are discussed and implemented in a study in which SO university students solved u-ord-association problems under continuous work or interrupted condttions. The interrup...
The dispersion mismatch between sample and reference arm in frequency-domain optical coherence tomography (OCT) can be used to iteratively suppress complex conjugate artifacts and thereby increase the imaging range. In this paper, we propose a fast dispersion encoded full range (DEFR) algorithm that detects multiple signal components per iteration. The influence of different dispersion levels o...

In this intelligent fault detecting system in an optical fibre used to find the fault in optic fibre line. To design a fault monitoring module and find the fault in the line says across the customer sides. The idea behind this module is to monitor the received power supply in optical fibre using a Microcontroller. Laser output power monitoring circuit is designed using ISIS simulator to monitor...
Let Ng(d) be the set of primes p such that the order of g modulo p, ordp(g), is divisible by a prescribed integer d. Wiertelak showed that this set has a natural density, δg(d), with δg(d) ∈ Q>0. Let Ng(d)(x) be the number of primes p ≤ x that are in Ng(d). A simple identity for Ng(d)(x) is established. It is used to derive a more compact expression for δg(d) than known hitherto.
In recent years much work has been devoted to the development of erbium-doped fibre lasers [ 1-91. because a broad zain bandwidth centred nearly I.54 urn. cegative group velocitv dispersion and tight confinement of optical field allow the exploitation of nonlinear optical effects for very efficient generatlon of ultra-short optical pulses. In the last few years several schemes of fibre soliton ...
