Assessing the Performance of Sugarcane Bagasse Ash with Portland Pozzolana Cement
Abstract: Cements which are used for construction work are generally OPC/PSC or PPC and the production of this kind of cement not only consumes huge amount of the natural resources i.e. limestone and fossils fuel, also the world cement production generates 2.8 billion tons man-made greenhouse gas annually. The uses of the industrial and agricultural wastages in concrete partly as cement or any other ingredients replacement are therefore eco-friendly, economic and …

Strength Assessment of RCC Beams Subjected to Corrosion
Abstract: The damage assessment of civil structural members is one of the most important and recently emerging fields in engineering. Deterioration of a structure may occur due to a host of factors such as poor workmanship, improper maintenance, atmospheric effects, accidents, natural calamities. Certain causes like environmental effects, natural calamities cannot be controlled. Therefore, durability of concrete structures especially those exposed to aggressive environments is of great concern. Many deterioration causes …

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 …
