Review on Automated Elevator-an Attentive Elevator to Elevate using Speech Recognition

Elevator has over time become an important part of our day-to-day life. It is used as an everyday transport device useful to move goods as well as persons. In the modern world, the city and crowded areas require multiform buildings. According to wheelchair access laws, elevators/lifts are a must requirement in new multi-stored buildings. The main purpose of this project is to operate the elevator by voice command. The project is operating based on voice, which could help handicap people or dwarf people to travel from one place to another without the help of any other person. The use of a microcontroller is to control different devices and integrate each module, namely- voice module, motor module, and LCD. LCD is used to display the present status of the lift. The reading edge of our project is the “voice recognition system” which genet’s exceptional result while recognizing speech.

Higher Order Reduction of Uncertain Systems: Affine Arithmeti

In this paper the Modified Routh Approximation (MRA) and Affine Arithmetic (AA) methods are investigates for obtaining the reduced order model (ROM) of SISO, discrete & MIMO uncertain systems into lower order system. Rigorous study and analysis of physical system direct to the outcome of systems with uncertainty instead of certain coefficients. Thus, systems having uncertain but bounded parameters known as uncertain systems are under consideration in this paper. An effective algorithm to determine the reduced order model is proposed here. This proposed methodology is verified using numerical examples available from the literature.

Two Legs Voltage Source Converter with DSTATCOM, T-Connected Transformer for Power Quality Improvement

The numerous loads can impact the working environment and performance of the source apparatus. Hence, the reimbursement of this current will help in enhancing the presentation of the power system apparatus. This paper presents the strategy and employment of a Distribution Static Compensator (DSTATCOM) with the T-Connected transformer for compensation of load neutral current in the presence of three-phase unbalanced linear load. There are different types of control strategy in that one of the best methods is the unit vector template method-based control algorithm has been implemented for the control of the proposed DSTATCOM. The proposed model has been simulated in a SIMULINK/ MATLAB environment. The simulation results show the effectiveness of the proposed algorithm.

Metering and Reactive Compensation Unit (MRCU) for Improved Energy Efficiency and Management - Supply of Electricity to Agricultural Consumers

In order to meet the growing demands of electricity, it is imperative to increase the efficiency of distribution system and reduce all wastage of energy. In this paper, the data from the distribution companies and regulatory bodies are analysed to identify the inefficiencies existing in the electricity distribution to the agriculture consumers of the state of Gujarat in India. The primary causes for the inefficiencies in the system are absence of effective monitoring and correct and reliable data on the usage of electricity by agricultural consumers, and the technical loses of electricity on account of low Power Factor and poor voltage regulation. The paper proposes a comprehensive solution to address the identified problems by way of installing a Metering Reactive Compensation Unit (MRCU) independent of consumers’ energy meters. MRCU will contain capacitors for reactive compensation, relay and switching unit, metering unit for current, voltage, Kilowatt, KVARH and KWH, and LORA based communication module for 24x7 data capture. The data captured at the cloud level will be analysed by a head end software system for real time reports and corrective actions. The estimated monetary benefits from installing MRCUs for entire Gujarat’s agricultural consumers is estimated to be Rs 1500 Crore in a year, apart from an estimated energy saving of close to 2000 MUs per year.

The Fume Detecting Dual Tone Modulation Frequency Based Rover Using BLDC Motors

The purpose of this project is to improve the control and precision of any rover by replacing the conventional DC motors or servo motors with the BLDC motors. The BLDC motors are much accurate to control because of the sensors they are equipped with. The telephonic signal from the receiver generates two frequencies one is a higher frequency and the other is a lower frequency. The higher frequency is used to drive the motors. The signal is then received by the receiver phone which then transmits the DTMF signal to the DTMF decoder. The DTMF decoder then decodes the signal and then transmits to the Gate Driver IC (which is connected to the Arduino for motor control). The Gate Driver IC which has the BLDC motors connected to it drives the motors. Furthermore this rover is being operated by Dual Tone Modulation Frequency (DTMF). In addition the rover is equipped with a Gas Sensor.

Study of Power Quality Phenomenon Based on Design and Simulation of Boost Type PFC Converters

This paper present design and simulation of boost type Power Factor Correction (PFC) converter which improved the power quality. With the enormous development in the usage of power converters circuits like rectifiers which is non linear loads, the current drawn by these non- linear loads will not follow the supply voltage (i.e. non simulation). This results in high Total Harmonic Distortion (THD) and poor Power Factor (PF). Hence there is a need of converter topology to improve the PF and reduce line current harmonic. Boost type PFC converters is most popular topology for improving the PF in supply AC side. Average Current Mode (ACM) control technique is employed to control the boost converter in Continuous Conduction Mode (CCM). Simulation of proposed system is carried out using MATLAB/ Simulink platform.

Solar Autopilot Drone

Advances in technology have made the drone an affordable tool for various purposes. This article focuses on gaining knowledge of drone at a working and conceptual level. Firstly, there is a detailed explanation of the construction of the drone. Some of the most essential elements of a drone include frame, propellers, engine, system of power the electronic control and communication system. Whether you fly your drone for commercial or recreational purposes, staying in the air as long as possible is the goal. But of course, the battery life of the drone can put a damper on how much you can accomplish while you’re flying.Batteries serve as a major drawback because they get exhausted after 15 minutes of flight and thereby landing the drone on ground. The batteries used for powering the drones are lithium-polymer batteries.This project aims to provide an ingenious solution to this hurdle by introducing the current popular photovoltaic system into the UAV power system design.Solar drones use solar cells powered directly from the sun and solve major issues related to conventional drones such as increasing the flight time and risk of the drone losing connectivity with its controller. The design is to be modular for easy module upgrade and replacement. Using photovoltaic system minimizes the environmental impact, an issue that can be controversial for large projects built for utilities because they tend to spread across hundreds of acres of land in remote regions.

Biomass Extraction of Energy Transformation

The focus of this is to make available clean energy, where there is a need for electricity production or energy infrastructure. An anaerobic digester contains an oxygen free environment that allows microorganisms to break down the organic material to harvest biogas (methane). Once the biogas is formed it can be used for different applications to aid the developing world. There are already millions of biogas plants in operation throughout the world. In Germany and other industrialized countries, power generation is the main purpose of biogas plants; conversion of biogas to electricity has become a standard technology. Biomass can become a reliable and renewable local energy source to replace conventional fossil fuels in local industries and to reduce reliance on overloaded electricity grids. The concept presented is to use manure from farms to produce methane gas using anaerobic digestion.
