Architectures v/s Microservices

As it evolves, technology has always found a better way to build applications and improve their efficiency. New techniques have been learned by adapting old technologies and observing how markets shift towards new trends to satisfy their customers and shareholders. By taking Service Oriented Architecture (SOA) and evolving techniques in cloud computing, Web 2.0 emerged with a new pattern for designing an architecture evolved from the conventional monolithic approach known as microservice architecture (MSA). This new pattern develops an application by breaking the substantial use into a group of smaller applications, which run on their processes and communicate through an API. This style of application development is suitable for many infrastructures, especially within a cloud environment. These new patterns advanced to satisfy the concepts of domain-driven, continuous integration, and automated infrastructure more effectively. MSA has created a way to develop and deploy small scalable applications, which allows enterprise-level applications to dynamically adjust to their resources. This paper discusses what that architecture is, what makes it necessary, what factors affect best-fit architecture choices, how microservices-based architecture has evolved, and what factors are driving service-based architectures, in addition to comparing SOA and microservice. By analyzing a few popular architectures, the factors which help in choosing the architecture design will be compared with the MSA to show the benefits and challenges that may arise as an enterprise shifts their developing architecture to microservices

Rent-A-Car

Our goal is to build a data management system for a car rental company. This enables the admin to rent a vehicle to a customer. This system increases customer retention while simplifying vehicle and personnel management. The interface of this software car Rental System is very user-friendly. As a result, users will find it extremely simple to work on. Administrators can use this system to manage customer confirm and cancel booking requests, customer testimonials, and customer issues. The vehicle data can be entered into the system. Administrators can also modify or delete existing vehicle data. There is no delay in the availability of any car information; it can be captured quickly and easily whenever required. In this application, we had three primary responsibilities: admin, renter, and owner. Renters can locate their vehicles and communicate with the owners, owners can upload vehicle information, and administrators can manage accounts and vehicles in this application. We chose the PHP Codeigniter framework to build our car rental website, which includes HTML5, CSS3, Bootstrap, and Javascript for the user interface and MySql for the database

Future prediction of Population, Birth and Fertility rates in India

Background: Fertility rates have been declining worldwide over the past fifty years, part of a phenomenon known as “the demographic transition”. Aims & Objectives: To draw on life history theory to examine the relationship between population density and fertility rate in India over 74 years. Material &Methods: The association between population versus Birth rate and population versus fertility rate was found using Correlation Analysis, to fit the models using Least square methods. Results: A robust association was found between population and fertility rate, population and Birth rate over the analyzed time period. Population, Birth rate, and Fertility rate for one decade were also forecasted using the best least square method. Conclusion: The analysis shows that the population is on an increasing trend and the Birth rate and fertility rate have decreased tendency

Assessment of relationship between Hemoglobin and BMI levels in female college students and influence of diet and physical activity on these parameters

Anaemia and nutritional status through Body Mass Index (BMI) are two key indicators in National Family Health Survey of India. The objective of the study is to determine the correlation between Hemoglobin (Hb) and BMI values and to understand the effect of diet and physical activity on these two parameters amongst college girl students. A questionnaire covering food habits and physical activity of 200 female students (18-22 years age) was used for data analysis along with Hb and BMI values of the same subjects. No significant association was found between Hb and BMI values, but a significant association was found between physical activity and BMI. Diet consumption which included leafy and other vegetarian diet, eggs and meat has shown significant contribution for high Hb levels. The present study strongly provides evidence based conclusion for the relationship between diet, nutrition and Hb levels as well physical activity and BMI. A multiple regression model was developed to estimate Hb levels based on their food habits

Auto Student Attendance System Using Student ID Card via Wi-Fi

The aim of this project is to eliminate the paper-based attendance with auto attendance by using student ID card. Currently, there is a card based attendance used in companies and web based attendance is used in the universities. In the paper-based attendance the paper is often lost, while in the web based attendance when all the students try to log in at the same time, the server gets down. We came up with the solution of  having a Wi-Fi based attendance where there is no need of paper and login to the server. It can be done with the help of proximity card reader. When a student holds his card in front of the reader, it will read the card and send it to the database with the help of Wi-Fi module. The database will process data based on the time and date of receiving

Heating Oil Level Detection and Assistance Using Amazon Alexa

This work is used to bridge the gap between consumer and oil supplier by building a smart monitoring system with the help of  ESP8266 (Wi-Fi module) and  Alexa (Intelligent AI based Virtual Assistant). In the existing system, many oil tanks are inaccessible or buried under the ground. We came up with the solution  of  having a smart monitoring system where there is no longer need to read the oil level in the heating oil tank manually.  It can be done with the help of an ultrasonic sensor. When the consumer requests to check the oil level, ESP8266  retrieves the oil level from the ultrasonic sensor and sends it to Alexa

Authentication Using Voice Recognition and Timestamp OTP

This work is related to providing security using authentication. By looking into other research works, we have found many attacks while logging in a system like phishing attack, brute force attack, etc. We came up with a solution which uses voice biometric as a recognition technique and also adding a time stamp one-time password (TOTP) which will help in providing a better authentication during login. Voice recognition technique uses a Bark frequency scale mapped with the input voice signal and made into spectral analysis with cepstral coefficients which is tough to forge, and adding this with TOTP provides stronger security in today’s Internet of Things (IOT)

AN EFFICIENT RECOVERY APPROACH FOR DISTRIBUTED SYSTEMS

In this work, we have addressed the complex problem of recovery for concurrent failures in distributed computing environment. We have proposed a new approach in which we have dealt with effectively both orphan and lost messages. The proposed check pointing and recovery approaches enable a process to restart from its recent checkpoint and hence guarantees the least amount of re-computation after recovery. It also means that a process needs to save only its recent local checkpoint. The proposed value of the common check pointing interval enables an initiator process to log the minimum number of messages sent by each application process
