 Abstract

The production of cement involves a lot of raw material and processing, which increases the cost of production. An enormous amount of wastage is produced from cement manufacturing industries which results in the dwindling of natural resources. This leads to the emission of greenhouse gases, majorly CO2. To overcome this, the concept of partial replacement of cement with mineral admixtures in concrete is introduced. In this paper, bentonite clay is used as a partial replacement (5%,10%,15%) of Ordinary Portland Cement (OPC) in concrete and several tests were conducted like workability of concrete, compressive strength, split tensile strength and flexural strength and the results were discussed in this paper.

 Abstract

The COVID-19 made an impact in the Roadway transportation sector towards the public. In India, transportation is the most affected sector due to the pandemic situation and most of the public avoid public transportation because of COVID. The transportation sector has been one of the primary victims of COVID-19. From rickshaw pullers to bus drivers, all have been affected economically by the pandemic. India's overall energy demand fell down. In this situation people's routine work effected and also people can manage their health and safety. Based on collected data from 120 online respondents during COVID-19, This study is about to examine roadway transportation management towards the general public. How people travel safely on the covid situation how they are struggled due to fewer transportations. The study used SPSS analytical tools such as Correlation, ANOVA, and Independent T-test. This tool is used and found how impacts roadway public transportation. Finally, the result showed that in this pandemic situation most of the people were affected their daily work due to less transportation and they can manage it.

 Abstract

Financial products act as an investment avenue and supply the specified financial security to the investors supported the risk-return profile of the financial products. In the past, traditional financial products were offered in India by banks (deposit account, credit account), life insurance Corporation (LIC), and postal department (recurring deposit, National Saving Certificate, Kisan Vikas Patra). However, in recent years with the arrival of liberalization of monetary services industry, diverse financial products are introduced like mutual funds, shares, derivatives, life and non-life insurance schemes (Unit Linked Investment Plans (ULIPs), pension plans, children education plans, etc.). Investment preference differs from person to person, as every individual behaves differently while investing. Investment behavior of a private is guided by his own set of circumstances. With an expectation of generating high returns over a period of your time and certain levels of risk, individuals invest in several financial products. The present study is an effort to research the investment preferences of salaried individuals towards financial products supported various demographic factors.

 Abstract

Railways give the most cost effective and most convenient mode of traveler transport each for long distance and residential district traffic. Also, most of the transport in India is being dole out by railway network. Still, accidents are the most important concern in terms of railway track crossing and unidentified crack in rail tracks in Indian railway. Most of the train accidents occur in railway tracks because of faults in tracks leading loss of precious life and loss of economy. So there is need of new technology that is strong, economical and stable for track detection in railway track. This paper aims to propose a defected rail track detection system. This project discusses a railway track crack detection using image processing and is a dynamic approach which combines the use of Wheel encoder module to send alert messages of information of location and GSM. A Raspberry Pi 4 is also used to control and coordinate the activities of these devices. This project prevents train derailment by detecting a crack in railway track using image processing technology

Abstract : Experiment were conducted to evaluate the alterations in different metabolites caused due to the sublethal concentration (Lc10) of the leaf extact of Annona squamosa and latex of Euphorbia nerrifolia exposed for 24 and 48 hours were studied in freshwater snail Lymnea acuminata. The protein and glycogen content was decreased in the foot at all exposure periods. The toxic effect of herbicides was time as well as dose dependent.

 Abstract

The complexity of the power system and level of integration of Wind energy into the power system has significantly increased, causing voltage instability problem across many power systems. Voltage stability is concerned with maintaining appropriate voltage profile across all the buses in the power system .Maintaining a stable and secure operation of a power system is therefore a very important and challenging issue.In this thesis the voltage stability analysis of Doubly Fed Induction Generator (DFIG ) integrated system was analyzed using Power system Analysis Toolbox.(PSAT)The analysis of voltage stability was carried out using Bifurcation methodology. The IEEE14 bus system was re modeled by integrating DFIG at bus number 1.The Power Flow analysis was carried out using Newton Raphson method and the Voltage profile at all the buses were noted.The Eigen value analysis was carried out for the given test bus system and it was identified that there are no positive Eigen values indicating that the system possesses voltage stability and there are eight complex pair indicating that the IEEE14 bus system may cause small signal instability.The Time domain analysis was carried out to study the Small Signal stability on rotor speed and Excitation voltage and it revealed that the system shows increased level of damping there by indicating that the integration of DFIG improves Small Signal Stability.
