 Abstract

Grass cutting is a time- consuming and labor-intensive process. The technology that is available in the present-day for grass cutting operation is mostly the manually handled Diesel operated cutter. These types of equipment operating under non-conventional sources of energy emit green- house gases and pollute the environment and also responsible for climate change. These grass cutters are also a source of noise pollution that adversely affects the health of the cutter and the surrounding people. The cost of diesel is another matter for consideration. To mitigate the problems of the conventional cutter, a solar-powered automatic grass cutter is designed. Solar energy is chosen because it is free of cost, pollution-free and renewable form of energy. The automation is done to reduce the need for labor. The design consists of a solar panel of rated power 20 W, Solar charge controller of voltage 12 V and current 10 A, sealed Lead Acid battery of 7Ah, 24 V high speed DC motor and cutter blades. Various sensors like ultrasonic and temperature sensors and microcontrollers are used for the automatic function of the machine. The paper summarizes all the design parameters, the working principle, design calculations on the basis of the solar radiation data of Guwahati city and also the cost analysis of the designed system.

 Abstract

This study seeks to develop our understanding of the agency involved in construction industry. The goal is to identify the value-oriented reasons for Agencies to utilize specific influence strategies. The study argues that Agencies expectations of project value creation explain the Agencies influence strategies utilized. Social responsibility implementation in construction projects relies on the active involvements by multiple internal and external stakeholders. Stakeholder influences are an important driving force for resolving or alleviating the social and environmental problems in construction activities. The study is to be carried out to evaluate the interrelationship between the agencies like Architectural Agency, Structural Engineer, and Contractors. The goal of the study id to find out the factors influencing the work statics of the stakeholders and affecting their mutual as well as social responsibilities

Mode of education has changed from face to face teaching to online learning. Students do not have need to go schools, they are learning at their home with their own speed. As they are getting education at home so parents are very much involved in their teaching learning process. Research studies indicate that parents� influences and involvement affect the quality of child learning, so when they are taking their classes at home it is necessary to know the parents point of view on the online classes. Their view can increase the effectiveness of online classes. Present study indicates the parents� perspective on the online classes of their child at home by their school teachers.

 Abstract

The outbreak of the Covid-19 pandemic is an unexpected shock to the Indian economy. The economic impact of the 2019-20 coronavirus pandemic in India has been largely detrimental. The economic impact of the 2019-20 coronavirus pandemic in India has been largely detrimental. The economy was already in a dismal state before the Covid-19 attack. With the protracted freeze across the country, the global economic downturn and the resulting disruption in demand and supply chains, the economy is likely to face a long period of slowdown. The magnitude of the economic impact will depend on the duration and severity of the health crisis, the duration of the blockade and how the situation develops once the blockade is lifted. In this document we describe the state of the Indian economy in the period prior to Covid-19, evaluate the potential impact of the shock on various segments of the economy, and analyze the policies announced so far by the central government and the Reserve Bank of India to improve the economic shock and present a set of policy recommendations for specific sectors.

Abstract: The toxicity of Sodium fluoride (NaF) to fresh water fish L. rohita was evaluated after exposure to the study of acute (96hrs.) toxicity. The changes of biochemical parameters in muscle, liver, gill and kidney tissues were recorded. Muscle shows the greatest loss of protein due to exposure of NaF followed by liver, gill and kidney. Liver shows significant reduction of lipid and glycogen in comparison with other selected tissues of the experimental fish species.

Soft skills are arguably more challenging to develop, since they have little to do with knowledge or expertise, but are instead closely linked with a person�s character. It requires a commitment to self-development and ongoing practice to improve your soft skills. In comparison, hard skills are more learned, technical and knowledge-based skills that you can develop, for example, through higher education. It goes without saying that these skills are also vital to establishing your success, and work in tandem with your soft skill set.

The present work aims to examine the similarity and variation between concrete mix design by using the IS method and ACI method, also to suggest suitability of mix design through experimental procedure. In this research work 53 grade of OPC, locally available fine aggregate and coarse aggregate were selected based on IS 456-2000 and IS 10262-2009 standards for determining quantities and proportion of concrete having grade M-30. It is observed that water cement ratio is almost identical in the IS method and ACI method. The amount of cement is highest used in IS method were, the percentage of FA is lowest in IS method and highest in ACI method. The concrete cubes having dimension 150�150�150 mm are used and to find out compressive strength values using various mix designs at 7 days and 28 days period and finally compare the results by checking strength and durability criteria.

 Abstract

In today�s growing world, we all know how important education have been and how important the performance have become for getting higher education or and kind of jobs. So for the calculation of performance a human take certain amount of time and yes it do consume time. So here we take certain factors like attendance, marks throughout, practical knowledge, extra skills, etc. So, we can assume time consumption for calculation of these many factors. So, here we have designed a system which would help in calculation of performance and marking attendance in a very easy and convenient method. Also, as we know marking and managing a large data of attendance is challenging as analyzing it and get the analyzed data isn�t easy for human so we used NODEMCU and components to manage the attendance of student and get the analyzed data in short period of time and only mark attendance of the real student who passes the parameters such as on time and the student isn�t marking proxy. It is user-friendly, secure and affordable system.

 Abstract

Blindness is a state of lack of visual perception, which leads to the inability to see anything, including light. Complete blindness is the total absence of light, but partial blindness represents the lack of integration in the growth of the optic nerve or visual center of the eye. In some cases lens, occupied glasses will help to improve partial blindness. Low vision cannot be corrected by visual aids such as glasses and contacts. In those situations, it is too difficult to find or detect obstacles in front of them, which makes it dangerous. They need some aid to feel safe while navigating. Conventional Blind canes are widely used for assistance, but it has too many limitations. Thus the current scenario needs a technologically developed cane. Thus, Smart cane comes as a proposed solution for visually impaired people. In this experimental work, we implanted a simple, economical, and user-friendly smart blind guidance system. This system is designed to improve the mobility of both visually impaired and blind people, and to remove the curse of blindness, to make them self-dependent to do their daily routines. The proposed work includes the design of a lightweight adaptable cane with multiple sensors connected to an Arduino board, along with a handle head and sticks elongator. A conventional white cane forms the main base frame of the device, ultrasonic and infrared sensors are mounted at appropriate locations to detect obstacles and it can scan a predetermined area, both known and unknown locations around blind by emitting-reflecting waves with the help of that blind stick. The equipped sensors send signals to an Arduino programmed board, which communicates with the alarm unit that comprises a buzzer and vibrator and gives some recorded audio clips to navigate the blind people safely. An audio jack is also available in the blind cane whose presence is not found in other conventional canes. The system can also control the peripheral components that alert the user about the obstacle�s shape, material, and direction. The device is lightweight and is been powered by a battery. Thus the system is easy to use and is an innovative reasonably priced solution to blind and visually impaired people. The power consumption is too low, and the stick is economic over the conventional one.
