Gravitational Analysis of Einstein-Non-Linear-Maxwell-Yukawa Black Hole under the Effect of Newman-Janis Algorithm

In this paper, we analyze the rotating Einstein-non-linear-Maxwell-Yukawa black hole solution by Janis-Newman algorithmic rule and complex calculations. We investigate the basic properties (i.e., Hawking radiation) for the corresponding black hole solution. From the horizon structure of the black hole, we discuss the graphical behavior of Hawking temperature $T_H$ and analyze the effects of spin parameter (appears due to Newman-Janis approach) on the $T_H$ of black hole. Furthermore, we investigate the corrected temperature for rotating Einstein-non-linear-Maxwell-Yukawa black hole by using the vector particles tunneling strategy which is based on Hamilton-Jacobi method. We additionally study the graphical explanation of corrected $T_H$ through outer horizon to investigate the physical and stable conditions of black hole. Finally, we compute the corrected entropy and check that the effect of charged, rotation and gravity on entropy.Comment: 12 Pages, 8 figures, Published in Physica Script

Being and doing gender: Using drawing as a method to relate to the self, environment and others

The research explores drawing as a method to understand the ways through which we absorb power structures that define our mannerisms in public spaces. Drawing in different public spaces of the cities of Lahore and Helsinki, my interest is in observing and documenting the interactions I have with passers-by. I seek to uncover the ways in which drawing can make visible the relations of power between sexes. The habit of drawing began as a way to take up space as a female gender in the predominantly male oriented public spaces of Lahore. I use drawing as a tool to capture fleeting moments when we pass each other by and power balance shifts from one to the other. The process slows down these moments and highlights the intricate web of power and vulnerability. Our bodies are shaped by our interactions with others and our environment. Drawing creates a dialogue between the self, environment and others in public spaces. The multisensory experience of being in public spaces is investigated through the process of drawing where my physical appearance creates interactions with people from different walks of life. And if experiences within these spaces can come to shape our bodies, then the act of drawing is that bodily experience that can lead to different ways of relating to the self, environment and others

An improved grey wolf with whale algorithm for optimization functions

The Grey Wolf Optimization (GWO) is a nature-inspired, meta-heuristic search optimization algorithm. It follows the social hierarchical structure of a wolf pack and their ability to hunt in packs. Since its inception in 2014, GWO is able to successfully solve several optimization problems and has shown better convergence than the Particle Swarm Optimization (PSO), Gravitational Search Algorithm (GSA), Differential Evolution (DE), and Evolutionary Programming (EP). Despite providing successful solutions to optimization problems, GWO has an inherent problem of poor exploration capability. The position-update equation in GWO mostly relies on the information provided by the previous solutions to generate new candidate solutions which result in poor exploration activity. Therefore, to overcome the problem of poor exploration in the GWO the exploration part of the Whale optimization algorithm (WOA) is integrated in it. The resultant Grey Wolf Whale Optimization Algorithm (GWWOA) offers better exploration ability and is able to solve the optimization problems to find the most optimal solution in search space. The performance of the proposed algorithm is tested and evaluated on five benchmarked unimodal and five multimodal functions. The simulation results show that the proposed GWWOA is able to find a fine balance between exploration and exploitation capabilities during convergence to global minima as compared to the standard GWO and WOA algorithms

Comparative Study on Two Commercial Strains of Saccharomyces cerevisiae for Optimum Ethanol Production on Industrial Scale

Two commercial strains of Saccharomyces cerevisiae, Saf-Instant (Baker's yeast) and Ethanol red (Mutant) were compared for ethanol production during hot summer season, using molasses diluted up to 6-7° Brix containing 4%-5% sugars. The yeasts were propagated in fermentation vessels to study the effects of yeast cell count and varying concentrations of Urea, DAP, inoculum size and Lactrol (Antibiotic). Continuous circulation of mash was maintained for 24 hours and after this fermenter was allowed to stay for a period of 16 hours to give time for maximum conversion of sugars into ethanol. Saccharomyces cerevisiae strain (Saf-instant) with cell concentration of 400 millions/mL at molasses sugar level of 13%–15% (pH 4.6 ± 0.2, Temp. 32°C ± 1), inoculum size of 25% (v/v), urea concentration, 150 ppm, DAP, 53.4 ppm and Lactrol,150 ppm supported maximum ethanol production (8.8%) with YP/S = 250 L ethanol per tone molasses (96.5% yield), and had significantly lower concentrations of byproducts. By selecting higher ethanol yielding yeast strain and optimizing the fermentation parameters both yield and economics of the fermentation process can be improved

Dynamic Modelling and Analysis of a Hybrid Power System of Floating Solar PV System for an Offshore Aquaculture Site in Newfoundland

In this article a hybrid power system, a combination of solar and diesel generator (DG) is modeled in MATLAB and the dynamic performance of the system are analyzed considering the design parameters. The said system is designed for an offshore aquaculture site located in Newfoundland, Canada. The paper presents a novel concept of evaluating the dynamic performance of floating solar PV panels over the water surface of the fish farm. The sizing and economic feasibility of the system were carried out on HomerPro. Design is modeled in MATLAB to analyze the impact of dynamic changes on system performance. The system is exposed to variable irradiance, temperature, and load side variations and simulated under each condition. The results presented here confirm the satisfactory and reliable response of the system in all scenarios. The designed system shall replace the existing power source (diesel gen) with green and economical energy resources and will be a great help to bring sustainability in the Canadian aquaculture industry
