 Abstract

With the increase in the number of mobile applications in the day to day life, it is important to keep track as to which ones are safe and which ones aren't. One can't judge how safe and true each application is based only on the reviews that are mentioned for each application. Hence it is necessary to check and initiate a system to make assured that the apps present are genuine or fraud. The objective is to develop a web system in detecting fraud apps before the user downloads by using sentimental analysis and support vector machine. Sentimental analysis is to help in determining the emotional tones behind words which are expressed in online. This method is useful in monitoring social media and helps to get a brief idea of the public's opinion on certain issues. The user cannot always get correct or true reviews about the product on the internet. The reviews may be fake or genuine. Analyzing the reviews involving both user and admins comments, we can determine whether the app is genuine or not. Using sentimental analysis and support vector machine, the machine is able to learn and analyze the sentiments, emotions about reviews and other texts. The manipulation of review is one of the key aspects of App ranking fraud. By using sentimental analysis and support vector machine, analyzing reviews and comments can help to determine the correct application for both Android and iOS.

 Abstract

Due to the widespread integration of renewable energy sources in DC microgrids, these microgrids are highly vulnerable to fluctuations in power generation, particularly concerning voltage stability. To mitigate these fluctuations, a Hybrid Energy Storage System (HESS) comprising both a battery and a supercapacitor (SC) is employed. The distinct characteristics of batteries and supercapacitors make them an ideal combination for applications in HESS. The HESS is connected to the DC microgrid through a double-input bidirectional converter, offering decoupled control of battery and supercapacitor power, along with facilitating energy exchange between the storage components. This paper introduces a modeling approach for the double-input bidirectional converter and designs a controller for voltage regulation in a DC microgrid. The modified operation of the converter enables the use of the same controller for both HESS charging and discharging operations, creating a unified controller. The designed controller proves effective in rejecting disturbances from both the source and load sides while ensuring the voltage stability of the DC microgrid. The proposed modified operation of the bidirectional converter maintains the State of Charge (SOC) of the low Equivalent Series Resistance (ESR) supercapacitor within the desired range. Simulation results validate the operation of the modified converter and the performance of the designed controller in maintaining voltage stability.

 Abstract

A key objective of this study is to examine how societal values, traditions, and historical influences have impacted how Kerala education is perceived and nurtured, as well as the intricate relationship between cultural evolution and education. Despite the evolution in significance and objectives of education over time, it remains one of the most important driving forces for human development. People's lives have been consistently impacted by the educational model and its continuous changes. Historically, Kerala has had a long history of educational progress due to early rulers' formulation of educational policies. This paper examines the influence of movements on Kerala's educational system. As a result of their concerted efforts, the Ezhava Movement, Nair Service Society, and Adivasi Gothra Mahasabha were able to increase access to education, improve the quality of education, and empower individuals. The Kerala State has been recognized as one of the literate states in the world and achieved commendable gender and spatial equality outcomes in the past two centuries due to the initiatives of public and private institutions.

 Abstract

Digital Marketing has made the remarkable changes in the marketing field. The strategies of Government which includes, 'Make in India', 'Digital India' by Prime Minister, has made the companies reach consumers even in rural places. This has also created many opportunities to entrepreneurs' to go every corner of the world. Companies to compete, has to reach most of the consumers and create place in the capital markets to sustain in the long run. This study examined the influence of digital marketing on consumer buying behaviour. The sample size was 124 respondents and the structured questionnaire was used for data collection. A Statistical Package for Social Sciences (SPSS) software was used to analyze the data. The findings of the study showed that there is a significant impact of online marketing on consumer buying behaviour.

 Abstract

This project is to make a robot car which will be helpful for mankind. This robot will collect data from remote place and able to send those data to a remote IoT cloud database. This robot car will be controlled via android mobile phone. We can control the movement of the robot car by sending instructions via Wi-Fi from our android phone. The robot car will receive instruction via the wi-fi and process data with Arduino microcontroller. Then it will move the robot car in all direction with the help of motor driver L298N by following the instructions received from android mobile phone. Then the robot will collect data of temperature and humidity from that place with the sensor DHT11 and send those data via Wi-Fi to the cloud database with the help of node MCU ESP32. Then the data will be shown as well as the remote place can be monitored from anywhere in the globe from the internet server used. The system is made in very low cost .These robot cars are equipped with Wi-Fi connectivity allowing users to control and monitor them remotely using their smartphones. The integration of IoT technology into robot cars enables seamless communication between the car and the user's smartphone. By connecting to the car via Wi-Fi users have the ability to send commands such as moving forward backward turning left or right and controlling the car's speed.

Concrete Is Used In All The Building Construction As Material Which Occupies A Unique Position In All The Modern Construction. Concrete Is A Mixture Of Fine Aggregate, Coarse Aggregate Cement And Water. Concrete Is One Of The Most Frequently Used Material Which Is Used Throughout The World Wide. Self-Compacting Concrete Is A Highly Fluid Form Of Concrete Which Consolidates Under Its Own Weight, Where Lightweight Aggregates Reduce The Dead Weight Of The Structure. Pumice Stone Is A Lightweight Aggregate Used For Lightweight Concrete. The Lightweight Is Formed Due To Escaping Of Gas From Molten Lava. In This Study An Attempt Is Compared With Conventional Concrete And Self-Compacted Lightweight Aggregate Is Made By Partial Replacement Of Coarse Aggregate With Different Ratios Such As 10%,20%,30% And40%. This Project Is Mostly Focused On Determining Mechanical Properties And Durability
