In this paper, a novel high voltage gain DC-DC converter based on coupled inductor and voltage multiplier technique is proposed. The benefits of the proposed converter are ultra-high voltage gain, low voltage stress across the power switch and very low input current ripple by employing a low current ripple structure (LCR) at the input side. A low on state resistance (RDS(on)) of the power switch can be employed since the voltage stress is a maximum of 25% of the output voltage and the conduction losses of the switch is also reduced. Design of a 1.9kW, 48V at the low voltage side and 430V at the high voltage side is done and verified by simulation. Simulation results show an efficiency of over 93% when operating in continuous conduction mode (CCM).

Wind energy is a hopeful renewable energy which is used to generate electricity. The kinetic energy present in the wind is converted into electrical energy by the principle of Wind Energy Conversion System. This effort approaches the performance enhancement by re-design, re-fabrication, and re-implementation of Permanent Magnet Synchronous Generator-based wind energy conversion system and data logging system. PMSG connected to the wind turbine converts wind power into electricity. The proposed hardware design of PMSG aims to achieve the overall improved efficiency of the wind turbine by 7-10% of the existing hardware design. In the proposed design of PMSG overall efficiency was improved by increasing the magnet grade, reducing the air gap, and changing the winding type. A web dependent supervising system has been recognized. A data logging system was used for collection of data on wind speed, generating power, and other related data. Besides, the stored data can be observed through the website depend on data showed by the Global System for Mobile Communications. So, the user can monitor related data through the website. The Load Management System was used to balance the supply of electricity

Hydropower generated systems are one of the common source to generate energy. The renewable energy generation system is designed to use the water flow from an overhead tank during normal consumption of water for domestic use. The system produces electricity from the potential energy of water flow through water pipelines by changing the kinetic energy of water into electricity. The electrical energy is stored in batteries for domestic purposes like lighting and other electrical applications. The system has two turbines coupled with generator, placed at the inlet and outlet pipe of the water tank. The status of water level is detected with the help of float sensor. The motor performs automatically according to the level of water. The generated power is informed to the user and then stored in a battery storage unit. When the energy saved within the battery is sufficient an inverter is switched ON for domestic use. During the normal time of working load receives power from the ordinary commercial line. The system is simulated with Proteus software and analysed.

A system for monitoring an infant's health is developed and described in this paper. In this system, smoke detector, sound sensor, temperature and humidity sensor, are interfaced with the controller Node MCU-ESP8266. In the system, ThingSpeak Cloud is used for the data processing. ThingSpeak Cloud is connected to the Wi-Fi based microcontroller. The behavior and the problems that are being detected can be easily notified to the parents apart from the doctors and nurses, So, that even the nurses or the doctors misses out by chance, the parents can handle the scenario. The collected data can be taken out as in the form of the csv format. This data can be easily put into the Machine Learning Model in order to predict the various problems that a baby might be suffering from. These predictions have been done solely upon the data collected from the individual baby. Furthermore, separate system-based report would be facilitated by the model itself

A TechDoc system has been developed for online management of pharmacies and consultation of doctors and presented in this paper. TechDoc serves the purpose of queue management outside pharmacies, by providing a delivery system of online ordered medicines from registered pharmacies nearby to customers’ residence; checking of symptoms using the free symptom checker that can diagnose a large number of diseases and gives relevant details on remedies for the diagnosed disease along with a video for home remedies of the particular disease; booking an appointment with a physical practitioner through the doctor’s consultation section in case the user is unsatisfied with the home remedies generated by the system. All these facilities are implemented into a single platform – a website accessible by any device, an android application especially for android phones and an IVR system to be accessed by the users who don’t have access to high end devices or internet connection. This innovative implementation helps in easy availability of essential services like, ordering of medicines, provisional diagnosis of curable disease and consultation of doctors, online and promoting social distancing.

Fraudulent detection is a large number of exercises that try to keep cash or property out of the way. Fraud surveillance is used in many businesses such as banking or security. At the bank, misrepresentation may involve producing checks or using a Credit Card taken. Different types of robberies can include misfortune or create a problem with the expectation of only a paid Layer Ensemble Method running other AI fields including collecting learning. Recently, there have been one deep group models deployed with a large number of classifiers in each layer. These models, as a result, require a much larger calculation. In addition, the deep integration models are available that use all the separating elements including the unnecessary ones that can reduce the accuracy of the group. In this experiment, we propose a multi-layered learning structure called the Two-Layer Ensemble System to address the issue of definition. The proposed framework is working with a number of weird filters to get the troupe jumper sity, in these lines being a technology in the use of equipment.
