Modeling of PV module with consideration of environmental factors

Abstract: This paper discusses the modeling of single-diode photovoltaic cell to estimate the maximum power with respect to changes in environmental factors that effects its efficiency performance. The parameters, i.e. resistances for the modeling of PV cell are determined for nonlinear I-V characteristics to replicate the maximum power point. These values are determined at various environmental factors like; dust, solar radiation intensity, shadow, temperature and wind velocity.

Adsorptive Separation of Cu2+ from an Aqueous Solution Using Trioctylamine Supported Montmorillonite

Abstract: Montmorillonite (Mt) was used to remove copper (Cu2+) ion from wastewater stream generated from industrial effluents. This clay was modified (Mt-TOA) by using an amine-based solvent, trioctylamine (TOA). Equilibrium and kinetic experiments were carried out to determine the effect of adsorbent amount (w, 0.05 g to 0.3 g for Mt, 0.001 to 0.006 g for Mt-TOA), initial Cu2+ ion concentration (C0, 8 mg·L–1 to 16 mg·L–1), pH (2 to 10), and contact time (t, 10 to 90 min) on the capacity of both adsorbents. With an increase in the adsorbent amount, the uptake capacity of Mt and Mt-TOA for Cu2+ ion was found to decrease but with an enhancement in the removal efficiency. The optimum amount of Mt and Mt-TOA was found to be 0.1 and 0.001 g, respectively. A better adsorption of Cu2+ ion was observed at low pH value of aqueous solution, and was found to decrease with an increase in the value of pH. In the kinetic experiments, the amount removal of Cu2+ ion reached to a constant value of 75.62 % with Mt (0.1 g) and 80.12...

Buckling analysis of thin rectangular plates with cutouts subjected to partial edge compression using FEM

Abstract: Purpose – The purpose of this paper is to present elastic buckling behaviour of simply supported and clamped thin rectangular isotropic plates having central circular cutouts subjected to uniaxial partial edge compression. Analysis is carried out for four different kinds of partial edge compression and it is extended to study the effect of aspect ratio of plate on buckling load.Design/methodology/approach – A finite element method technique is used in the current work to solve the buckling problem of plate using eight node quadrilateral element and plate kinematics based on first order shear deformation theory. Results obtained from finite element analysis are first validated for isotropic square plates, without cutouts, subjected to uniaxial partial edge compression with some earlier published literature.Findings – From the current work it is concluded that the buckling strength of square plates is highly influenced by partial edge compression, as compared to plate subjected to uniform edge compression; ...

Wavelet-ANN Model for Flood Events

Abstract: The observation of peak flows into river or stream system is not straight forward but complex function of hydrology and geology of the region. There are well established statistical approach to predict the flood events with their magnitude and frequency. Development of models based on temporal observations may improve understanding the underlying hydrological processes in such complex phenomena. Present work utilized temporal patterns extracted from temporal observations of annual peak series using wavelet theory. These patterns are then utilized by an artificial neural network (ANN). The wavelet-ANN conjunction model is then able to predict the flood event comparable to statistical approach. The application of the proposed methodology is illustrated with real data. The limited performance evaluation of the methodology show potential application of the developed methodology.
