This paper describes a first demonstration setup for the transparent transmission of two analog signals using Mode Group Diversity Multiplexing (MGDM). MGDM is an optical multiple-input multiple-output (MIMO) technique suitable for short-reach multimode fibre networks. In this demonstrator two baseband analog signals are transmitted together with out-of-band pilot tones. Measurements of the pil...

The optical transmission properties of two types of photonic crystals have been analyzed by using the transfer matrix method. The first one is the dielectric photonic crystal (DPC), and the second is the metallic photonic crystal (MPC). We found the dielectric and metallic photonic crystals have different transmission spectra. The effect of the most parameters on the transmission spectra of the...

We present a theoretical analysis of a remarkable phenomenon evinced by a periodic structurally chiral material—for example, a chiral sculptured thin film (STF) or a chiral liquid crystal—with a central 908-twist defect illuminated with normally incident, circularly polarized light. Based on the coupled-wave theory (CWT), an approximate but closed-form solution of the relevant boundary-value pr...

a matrix $pintextmd{c}^{ntimes n}$ is called a generalized reflection matrix if $p^{h}=p$ and $p^{2}=i$‎. ‎an $ntimes n$‎ ‎complex matrix $a$ is said to be a reflexive (anti-reflexive) matrix with respect to the generalized reflection matrix $p$ if $a=pap$ ($a=-pap$)‎. ‎in this paper‎, ‎we introduce two iterative methods for solving the pair of matrix equations $axb=c$ and $dxe=f$ over reflexiv...

A general purpose Gamma Box Counter is a large scale, high-resolution segmented gamma-ray nondestructive assay system for the assay of nuclear waste containers covering a wide range of composition, mass, and geometry. In order to accurately quantify the activity of the radionuclides in a waste container, a correction for the gamma-ray self-attenuation in the waste matrix must be estimated and a...

Block Data Transmission Systems (BDTS) are used in high speed wireless communication systems with time dispersive channel characteristics. Since Maximum Likelihood Block Detection (MLBD) requires huge amount of computation, Sphere Detection (SD) technique has been introduced as an alternative. This paper proposes an An Lattice Sphere Detection (AnLSD) technique for detection in block data trans...

In this research work an effective algorithm is proposed for Digital Image Transmission to happen without any losses. Proposed work provides a new symmetric key generation method for colour images. The encrypted image is obtained with the help of three OTP (One Time Password) which provide two public key of matrix size 4*4 and 8*8 along the image. To obtain original image from encrypted data, a...

We show in random matrix theory, microwave measurements, and computer simulations that the mean free path of a medium strength position an embedded reflector can be determined from radiation scattered by system. The are statistics transmission. transmission independent reflector. reflector's found, however, average dwell time for waves incident one side sample.

matrix metalloproteinases (mmps) are a family of neutral proteinases that are important in normal development, cellular differentiation or migration, angiogenesis, neurogenesis, wound repair, and a wide range of pathological processes such as oxidative stress and neuroinflammation. mmps have been demonstrated to increase the permeability of the blood–brain barrier (bbb) by degrading the compone...
