Problems of Daily Wage Workers Under Informal Sector During the Period of Lockdown and Thereafter: A Study in the Tinsukia Distract of Assam
Author: Dr. Moheswar Rajkhowa
Abstract
The workers who do not have regular working hours and wages, and work on temporary basis, earns money to support a household by working is considered as daily wage worker under informal sector. The Corona virus pandemic is having a serious impact on the living conditions of the daily wage workers. Due to the corona virus pandemic they have lost their jobs, their means for bringing food to their families. This paper is trying to finds out the challenges face by the daily wage workers during the period of lockdown and thereafter and also assesses how they and their household were impacted due to COVID-19 pandemic. The findings of the study revealed that loss of income, scarcity of work, decline in wages, increase Expenses and borrowings and increased health risk are the some of the basic challenges they have faced.
An Energy Storage Management and PV Active Power Control Strategies for Microgrids
Authors: Abdul Samad Ansari, Shaista Parveen, Jauhar Ali, Prakash Kumar Gupta, Irshad Ali
Abstract
A microgrid is a localized group of electricity sources and loads that normally operate connected to and synchronous with the traditional wide area synchronous grid (macrogrid), as the number of DC-generating renewable energy sources is higher as compared to AC-generating sources, lesser converter units are required. This increases the overall efficiency of DC microgrid. A DC micro grid system is using a power network that enables the introduction of a large amount of solar energy using distributed photovoltaic generation units. This research deals with the design and performance analysis of a DC microgrid with battery-supercapacitor energy storage system under variable supercapacitor operating voltage. MATLAB 9.4 is using to implement the model and analysis.
The Covid-19 Impact on Indian Education System
Author: Dr. P. John Victor
Abstract
The world is facing the biggest health issues for the past one year due to Corona Virus. As per the report of the WHO at the end of the June 2021, there are nearly 182 Million confirmed Covid-19 cases and nearly 4 Million Covid-19 deaths around the world. The spread of the decease is so speedy when we compare the second wave from the first wave and still it is being insisted by the WHO that the third wave is going to affect the children. All educational institutions have been kept closed to avoid spreading of Covid-19. Due to closing of schools and colleges the education system was transmitted from offline mode to online mode which would have been not possible to all people especially who reside in remote villages and tribal regions where the network facility may not be available with enough speed and people may not have smart phone facility. The Universities in India conduct semester examinations via online depends on the conditions of the regions where the school education boards have decided not to conduct examinations and promote to the next standard. Various entrance examinations and competitive examinations in India are in such critical conditions and so they have been postponed.

An Introduction for various multilevel security techniques for Multimedia Application
Authors: Patel Dipakkumar Dhansukhbhai, Dr. Mukta Agarwal
Abstract
The recent growth of networked multimedia systems has increased the want for the protection of digital media. Multimedia security is a form of content-based protection. A novel strategy is proposed for multimedia data safety by integrating Steganography and Visual Cryptography to enhance security, reliability, and efficiency; due to the fact, there will be usually new types of threats in the subject of information hiding. Safety of the information transmitted across the internet is an imperative issue, as it is affected by many serious problems such as hacking, duplications, and malicious usage of digital information. A novel strategy is proposed for multimedia information security employing integrating Steganography and Visual Cryptography (VC) to enhance security, reliability, and efficiency. The proposed method consists of two phases. The first segment is used to cover the message dynamically in a CoverImage1 by altering the variety of bits hidden in RGB channels based totally on the indicator value. VC schemes conceal the Cover Image2 into two or extra pix which are known as shares. In the 2d section, two shares are created from a CoverImage2 and the stego photograph created in the first section is hidden in these two shares. The shares are protected as they divulge nothing about the multimedia content. The CoverImage2, stego photograph, and the hidden message can be recovered from the shares barring involving any complicated computation. The proposed algorithm takes the benefit of all these strategies mentioned above thereby growing the reliability and secrecy of the multimedia statistics transmitted. This is carried out utilizing consisting of three phases namely, Encryption, Steganography, and VC, at the transmitter side. The message is changed into a cipher picture the usage of a key, hid into some other picture the use of Steganography by using changing it into an intermediate textual content and subsequently converted once more into an image. The proposed technique, therefore, achieves an excessive diploma of safety for facts. This method can be used to increase the security of web-based applications. Cryptography, VC, and Steganography play a major role in data security. Since this method incorporates all these three technologies for high-level multimedia security, a highly confidential message can be transmitted across the network confidently.
