Comparative Analysis of Power Penalty versus Crosstalk in Optical Active Network Components like Erbium Doped Fiber Amplifier, Raman Amplifier and Semiconductor Optical Amplifier
Abstract: AbstractOptical amplifiers boost the power of optical system without optoelectronics (O-E-O) conversion. The optical amplification process is accompanied by Amplified Spontaneous Emission (ASE) noise that accumulates along the transmission line and degrades the optical signal to noise ratio (OSNR). Intensity modulation in one channel causes crosstalk in the other channel via the change of the complex refractive index in the amplifier. In this paper, authors tried to calculate and compare …

Einstein Quantum Entanglement and Quantum Communication
Abstract: AbstractQuantum theory suggests that “What we predict must happen in laboratory.” Quantum entanglement was introduced by Einstein, Schrodinger, Rosen and Podolsky in 1935. But the actual experimentation regarding quantum entanglement started 70 years later. Quantum entanglement paves the way for many other quantum processes such as quantum communication, teleportation, and cryptography. The concept of quantum entanglement is very complicated because it is difficult to detect, is affected by environment and …

LBP-HOG-Statistical-Wavelet Transform Feature Based MCA Classifier
Abstract: Face recognition systems use computer algorithms choose specific, recognizable features on a person’s face. With a mathematical representation, the information is compared to data on other faces acquired in a face recognition database. The distance between the eyes or the shape of the chin are two examples of these characteristics. The job of matching several facial modes, such as visible and near infrared images, is known as heterogeneous face recognition. …
