In: Bioremediation of Methylene Blue from Synthetic Wastewater using Immobilized Cyanobacterial Consortium Beads, vol. 1, iss. 1, pp. 1-4, 2022.
Treating wastewater to remove dye economically and ecofriendly is a need of the hour. Since methylene blue is being used by various industries and has various environmental problems and health hazards associated with it, therefore it has been selected for the present case. Present study aims at bioremediation of methylene blue from synthetic wastewater using a calcium alginate immobilized cyanobacterial consortium collected from local pond nearby the campus of CVRCE, Bhubaneshwar, India. Growth study of the strain has been done. Optimization of methylene blue removal has been done by varying its initial concentration in the range of 25-75 mg/L. Maximum removal of 93% has been observed in the study using the immobilized beads in a batch process.

In: Performance of PV/Wind/Battery Hybrid Power System using Different MPPT Techniques, vol. 1, iss. 1, pp. 5-17, 2022.
Renewable energy sources have become a popular alternative electrical energy source where power generation in conventional ways is not practical. In the last few years the photovoltaic and wind power generation have been increased significantly. In this study, we proposed a hybrid energy system which combines both solar panel and wind turbine parameter to generate electrical power source of electrical and supplied to power grid station. Two control techniques are used to maximum power point tracking (MPPT). It is used in circuit wind turbine as well in solar to get maximum power. And second control technique is used at grid side converting DC-AC by voltage source converter. A simple control technique which is also cost effective has been proposed to track the operating point at which maximum power can be coerced from the PV system and wind turbine generator system under continuously changing environmental conditions. The entire hybrid system is described given along with comprehensive simulation results that discover the feasibility of the system. A software simulation model is developed in Matlab/Simulink.

In: Performance Analysis of Three-Phase Inverter using Different Techniques for the grid-connected PV system, vol. 1, iss. 1, pp. 18-24, 2022.
The model of a three-phase a voltage source inverter is examined based on space vector theory. SVPWM offers a improved outcome with the inverter as compared to the conservative SPWM technique for inverter. There is 15.5% upsurge in the line voltage of the inverter. SVPWM better exploit the available DC link power with SVPWM inverter. It has been revealed that the SVPWM method utilizes DC bus voltage extra competently and produces a smaller amount of harmonic distortion and easier digital realization in a three-phase voltage-source inverter. Results are verified by MATLAB/Simulink

In: Performance Analysis on Power Flow of a Threefeeder/ Multi-bus Distribution System using GUPQC, vol. 1, iss. 1, pp. 25-37, 2022.
In this paper, the power flow analysis through the GUPQC connected to the multi-bus/3-feeder distribution systems was distributed. a replacement controller theme for the series compensator of GUPQC supported the d-q theory to complete the supply facet voltage harmonics, voltage sag/swell and interruption was conferred. the applying of the planned controller to complete voltage imperfections of the network and for the development of the ability quality of the client masses was valid by the simulation results. Depth simulation studies were distributed by exploitation MATLAB/SIMULINK computer code to determine the power of the GUPQC to enhance power quality of the distribution systems underneath distorted offer voltage conditions.

In: Analyzing the non-linear effects and minimizing the dispersion of Elliptical cum Circular shaped Borosilicate Crown Glass Photonic Crystal Fiber, vol. 1, iss. 1, pp. 38-43, 2022.
The proposed design of Borosilicate crown glass photonic crystal fiber is for minimizing
the chromatic dispersion to low level. The Finite Difference Time Domain (FDTD) method along
with the transparent boundary condition (TBC) is used for preparation of this design. This
method is bringing to produce zero dispersion at 0.5μm to 1.5μm diameter of circular and
elliptical air holes. Such PCF have high potential to be used as a dispersion compensating fiber in
optical window. The refractive index is calculated with this method is equal to the conventional
Borosilicate crown glass i.e. 1.534. The proposed design is also used to show the non-linear effects
of the material used.
