 Abstract

In the last few decades the technology has rapidly grown and the continuous improvements made our life easy. Due to this people are more dependent on it. So this paper brings an idea of android based Home automation technology which can be controlled by voice recognisation. The system has three components: an arduino microcontroller for connecting the appliances, a Bluetooth module for signal transfer, and a smart phone running android application. Today almost everyone have a smart phone. So simply one can operate the home appliances with the help of the smart phone. An android application is installed in the phone and it is connected to home appliances with the help of Bluetooth module. Bluetooth has an encrypted 128 bit long shared key that keeps the data secure.

 Abstract

Li-Fi stands for Light-Fidelity. The technology is very new and was proposed by the German physicist Harald Haas in 2011. Li-Fi provides transmission of data through illumination by sending data through an LED light bulb that varies in intensity faster than human eye can follow. In this paper, discuss the technology in detail and a method is proposed to reduce noise from received data. Li-Fi is ideal for high density wireless data coverage in confined areas where there are no obstacles. Li-Fi is a wireless optical networking technology that uses light emitting diodes (LEDs) for transmission of data. The term Li-Fi refers to visible light communication (VLC) technology that uses as medium to deliver high-speed communication in a manner similar to Wi-Fi. Li-Fi provides better bandwidth, efficiency, availability and security than Wi-Fi and has already achieved high speeds in the lab. In the present paper the authors will give a detailed study on Li-Fi technology, and method to achieve accuracy. The experimental result shows that the proposed technique efficiently detects the noise and de-noising purpose is achieved.

 Abstract

Sentiment analysis is the process of determining the opinion or filling of a piece of text. Companies across the word implementing machine learning to do it automatically [1]. It is a supper use of opinion inside the text. Once we understand how the customer fills after analyzing their comments and reviews. One can identify what kind of things they like or dislike and built things like recommendation system. Or more target marketing systems for them. This paper discussed the different implantation model of sentiment analysis system with their advantage and disadvantages. This paper also included the some real world application where sentiment analysis system can be used. Different implementation challenges and other issues related to sentiment analysis system explored in this paper.

 Abstract

Abstract In these paper, we discuss and study about the placement of one of the most versatile flexible alternating current transmission system (FACTS) device which is unified power flow controller (UPFC). By using unified power flow controller we can control all power system parameters individually or simultaneously. But without placing these device in its critical position it is impossible to get a better power flow improvement. The purpose of this paper is to present a comprehensive survey of UPFC controller incorporated in load flow analysis for optimal power flow control. We also discuss different optimization techniques for the optimal placement.

 Abstract

This paper presents the study of power factor correction using boost converter: Comparing with ac to dc PFC the proposed PFC has lower requirements of power device ratings, which leads to lower cost, higher efficiency, and lower electromagnetic interference. New recommendations and future standards have increased the interest in power factor correction circuits; a review of the most interesting solutions for single phase and low power applications is carried out. They are classified attending to the line current waveform, energy processing, number of switches, control loops, etc. The major advantages and disadvantages are highlighted and the field of application is found.

 Abstract

Airborne network is an emerging field in the wireless networks. They can provide an interconnected digital data network between aircraft, and between aircraft and the ground. It has the potential to change how aircraft are monitored and tracked by the air traffic control system, and how they exchange information with and about other aircraft. Critical information such as weather, turbulence, and landing conditions can be transferred, as well as the distance between aircraft .In this paper we were discussing about the airborne internet, architecture of airborne internet ,working, advantages and its applications.

 Abstract

An analysis is performed to study the effect of thermal radiation and viscous dissipation on unsteady flow past an oscillating infinite vertical plate through porous medium with variable temperature, heat and mass transfer. The non- linear, coupled partial differential equations together with boundary condition are reduced to dimensionless form. The governing equations are solved using perturbation method. The results are obtained for Velocity, Temperature, and Concentration profiles for different physical parameters like Phase angle, Thermal Grashof number, Modified Grashof number, Permeability parameter, Eckert number, Prandtl number, Schmidt number and time. It is observed that heat and mass transfer, viscous dissipation and porous medium affect the flow pattern significantly.

 Abstract

The paper proposes an efficient implementation for IoT (Internet of Things) used for monitoring and controlling the home appliances via World Wide Web. Automation system uses the portable devices as a user interface. They can communicate with the network through an Internet gateway, by means of low power communication protocols like Zigbee, Wi-Fi, GSM etc. This paper aims at controlling appliances using Wi-Fi as a communication protocol and MSP430 controller as server system. The user here will move directly with the system through a web-based interface over the web, whereas appliances are remotely controlled through website. The server will be interfaced with relay hardware circuits that control the appliances running. The communication with server allows the user to select the appropriate device. The server communicates with the corresponding relays. If the web affiliation is down or the server isn't up, the embedded system board still will manage and operate the appliances domestically. By this we provide a climbable and price effective Automation system.
