A Review: Web Content Mining Techniques

Abstract: World Wide Web provides a powerful platform that stores and retrieves mass information. It becomes a time-consuming and uncomfortable task to search the information due to its unstructured and heterogeneous nature of data on the World Wide Web. Web mining is one of the popular techniques of data mining that is used to discover and extract useful information from web documents and its services. Web usage mining, web structure, and web content are three different categories of web data mining. Each of these categories has various methods, tools, and approaches to excerpt data from volume of information over the web. This review paper states various issues, while encountering information from the web and also states various problems occurred while finding appropriate information from the web. This paper also introduces different techniques and approaches of web content mining for different types of data. This paper also states various applications of web content mining.

Energy Management of Grid Connected Renewable Sources with Energy Storage Unit for an EV Charging Station

Abstract: The electrical vehicles selling increase in last few years due to availability of charging facility. The charging station located on highways defines public EV charging station plays an important role to fast charge of electrical vehicles. In this paper, grid-tied PV and energy storage unit base charging station design by considering different modes of operation. The MPPT base boost converter is used to extract maximum power from the PV. The charging–discharging of energy storage battery design by the buck-boost converter. Five EVs battery parameters are considered to calculate real-time EV load. For the uninterrupted charging of EVs, whenever PV and energy storage power are not available or the available power does not meet load demand throughout the day, the deficient power is taken from the grid. The optimal energy flow between PV, ESU, grid, and EVs is obtained by a PI-based current control strategy. The different operating modes of power flow among sources and EV load are designed, and the same is formulated and validated in MATLAB/Simulink.

Intersection Between Gender Equity and Solving Infertility Issues

Abstract: For several decades or perhaps centuries now, we have been discussing gender equity and related issues like male hegemony, acceptance and equal treatment of women/LGBTIA at workplace, sensitization of children and adults towards equity and empowerment. The aim of this paper is to explore and understand whether the same challenges and opportunities also exist when solving for infertility, specifically from the child’s perspective. Traditionally the focus on issues of infertility is from the adult perspective, this paper aims to look at it from the child’s perspective—the child born to solve infertility. Infertility is very traumatic and inequitable and few people talk about it and how will this silence help solve issues? Any child/human needs happiness and protection to thrive, how does inequity provide an environment for either? In fact, neither infertility nor gender equity are just “social justice” issues but are a “right to live” issue. The underlying issues envelope individuals to the extent it suffocates their “right to life” issues like being able to live freely at peace and happiness. While the circumstances of one’s birth either based on gender or caste or religion or race or creed or physically challenged or mentally challenged or born differently via Surrogacy are NOT in any person’s control, the issues surrounding their ability to live freely and pursue happiness in peace are often intersecting. As COVID has taught all of us in 2020 that there is great uncertainty coupled with complex issues and entire life gets disrupted overnight for individuals, families, communities, governments. We overcome that collectively. Similarly, inequity causes uncertainty and entire life gets disrupted for the affected. We must work together to overcome it. It is important to delve into this intersection of similar issues and raise awareness together instead of a piece-meal approach. Looking at the issues collectively may help us understand each other, build harmony and eventually work together to solve issues. Sometimes, we get caught up in a “Me First” approach with an end result of “We Last”. There are multiple issues crisscrossing each other; like a Rubik’s cube of inequity. Rather than debating the differences, let us work together on the commonalities of the underlying issues. This exploration is a hope that we can come together objectively and begin solving Rubik’s issues of inequity. Perhaps we start at the point of the intersecting issues, a commonality among us. And move away from a “Me First, We Last” paradigm. Lastly, as MeToo movement has shown that it is not just about sexual harassment or assault but when one tries to “solve” by asking for equity and justice, they often fall prey to decades and perhaps centuries of inequity, patriarchy, power, money, suppression of lies, stereotypes; not something which can be solved by one person and it takes time. Similarly, “solving” infertility issues also takes time and is not something to be solved by one (girl) child when facing the same issues. At the very least, is exploitation and abuse of a voiceless girl child to “solve infertility” in adult an equitable solution and by denying rights of a girl child, what have we really achieved from the perspective of gender equity?

An Experimental Study to Evolutes Performance of PV Module at Workplace

Abstract: This paper investigates the performance of a polycrystalline solar module at Government Engineering College, Patan, Gujarat, India. The experiments were carried out during September month on a 10-W PV module under variable climate conditions. The open-circuit voltage and short-circuit current observed. The PV module has the facility to change tilt angle and direction manually. The performance graph was designed based on monthly average solar irradiation and ambient temperature, variable tilt angle, and panel orientation. Results show that the PV module performs better when it is inclined and placed at a 24-degree tilt angle and panel orientation the in south direction. It is also observed that PV module generated 78% power of its rated maximum on average irradiation of 695.6 W/m2/day and average temperature of 30.6 °C. Experimental results compared with the HOMER Pro microgrid software data for the same location and received good agreement between them. Similar system design can be applied for future large-scale projects for same location.
