Biodecolorization of Textile Dye Effluent by Biosorption on Plant Biomass and Equilibrium Modelling
Abstract: AbstractDye effluent discharge into water bodies leading to water pollution. Each textile dye process requires a different amount of dye and also it generates a different amount of effluents. Most of the physico-chemical methods are insufficient and highly expensive. Biosorption is an alternative technology for the treatment of different textile and other effluents. Aquatic plants specially water hyacinth showed a greater potential to use as biotrap for textile effluent treatment. …

An Analytical Model for Sub grid Force-Equilibrium Approach in Submerged Vegetative Channel
Abstract: A new, analytical model of the vertical flow velocity profile of submerged vegetation has been developed. Velocity profile can be divided into three zones: linear zone which is closed to bed with linear velocitydistribution, logarithmic zone which involves the main channel without vegetative cover and the middle zone (transition zone) that is affected by the momentum of upper zone.

Numerical Model for Water Hammer in Homogeneous Equilibrium Two Phase Fluid
Abstract: Generally, water hammer can occur in any thermal-hydraulic systems. Rapid closing or opening of a valve causes pressure transients due to the sudden transformation of kinetic energy into the potential energy. The resulting high pressure surge upstream of the valve leads to the temporary increase in pressure. If the increased pressure surpasses the safety margin for the pipe, it can lead to failure of the pipeline. A mathematical model is …

A Secure Storage Model with Authentication and Optimal Key Generation Based Encryption
Abstract: In digital forensics, ensuring the secure storage of digital evidence is crucial. This paper introduces a new method that uses advanced encryption and key generation techniques to protect digital evidence throughout an investigation. Cloud forensics, a modern approach to digital forensics, aims to safeguard evidence from online hacking. However, storing all evidence in one central location can reduce its reliability. To address this, we propose a digital forensics architecture for …

Cointegration and Error Correaction Modeling for BSE and NSE Stock Prices Time Series Data
Abstract: AbstractEconometrician always have been observed that most of the economics time series are non-stationary. The ordinary least square technique could be applied to estimate the model parameters only if the variables have been found to be stationary, i.e., they do not have unit roots. Otherwise, an alternative approach has to be followed, which is ‘co-integration’. Co-integration is a method of finding out the long-term relationship between economic variables under consideration. …
