Li-Fi (Light Fidelity)-The future technology in Wireless communication pdf full ppt

Li-Fi (Light Fidelity)-The future technology In Wireless communication pdf full abstract presentation paper journal ppt
Abstract:Li-Fi stands for Light-Fidelity. Li-Fi technology,proposed by the German physicist - Harald Haas, provides transmission of data through illumination by sending data through an LED light bulb that varies in intensity faster than the human eye can follow. This paper focuses on developing a Li-Fi based system and analyzes its performance with respect to existing technology. Wi-Fi is great for general wireless coverage within buildings, whereas Li-Fi is ideal for high density wireless data coverage in confined area and for relieving radio interference issues. Li-Fi provides better bandwidth, efficiency, availability and security than Wi-Fi and has already achieved blisteringly high speed in the lab. By leveraging the low-cost nature of LEDs and lighting units there are many opportunities to exploit this medium, from public internet access through street lamps to auto-piloted cars that communicate through their headlights. Haas envisions a future where data for laptops, smart phones, and tablets will be transmitted through the light in a room. Keywords—Li-Fi, Wi-Fi, high-brightness LED, photodiode,wireless communication.

Energy-Efficient Next-Generation Optical Access Networks full paper download

Energy-Efficient Next-Generation Optical Access Networks pdf full abstract presentation paper journal ppt
Abstract: Energy efficiency has become an increasingly important aspect of network design, due to both the increasing operational costs related to energy consumption and the increasing awareness of global warming and climate change. This article addresses the energy consumption of different next-generation optical access solutions beyond 10G TDM PONs. It is assumed that next-generation optical access should be able to provide sustainable data rates up to 1 Gb/s per subscriber with a passive fan-out of at least 1:64. Promising system candidates that meet these criteria are compared and analyzed in terms of energy consumption. Candidate PON solutions are also compared to architectures based on point-to-point fiber. A systematic approach is developed for the energy consumption comparison. The analysis is based on estimates of power consumption for key components in next-generation systems. Among the considered candidates, we find that WDM-PON based on RSOA, stacked 10G TDM-PON, and point-to-point fiber offer the lowest power per line potential.

Driving without wheels and Flying without wings seminar paper

Driving without Wheels, Flying without Wings full presentation paper journal ppt
Abstract: This paper “Driving without wheels, Flying without wings” deals with the present scenario of magnetic levitation (maglev) with Linear induction motor (LIM) .The magnetically levitated train has no wheels, but floats-- or surfs-- on an electromagnetic wave, enabling rides at 330 miles per hour. By employing no wheels, maglev eliminates the friction, and concomitant heat, associated with conventional wheel-on-rail train configurations. There are two basic types of non-contact Maglev systems Electro Dynamic Suspension (EDS), and Electro Magnetic Suspension (EMS). EDS is commonly know as "Repulsive Levitation," and EMS is commonly known as"Attractive Levitation." Each type of Maglev system requires propulsion as well as "levitation." The various projects above use different techniques for propulsion, but they are all variations of the Linear Induction Motor(LIM) or Linear Synchronous Motor (LSM).The conversion to a linear geometry has a far greater effect on induction motor performance than on that of synchronous motors. The cost of making the guideway is a high percentage of the total investment for a maglev system. The comparison looks even better for maglev when the terrain becomes difficult. Many of the tunnels, embankments, and cuttings necessary for roads and railroads are avoided because maglev guideways can be easily adapted to the topography. The Maglev system requires a slightly larger start-up capital construction cost, its operating cost-- because it deploys electricity in electromagnets in an extraordinarily efficient manner, rather than using as a fuel source coal, gas or oil-- can be one-half that of conventional rail. The crucial point is that maglev will set off a transportation and broader scientific explosion. Key words: Magnetic levitation , Levitation , Propulsion , Linear induction motor(LIM).

Design and Visulization of Space Colony Full Paper

Abstract: Lewis One is a qualitative space biosphere design. It is intended to house 10,000 residents in a cylinder large enough for a 1g rotating habitat module and construction facilities to reproduce the module. The shielding, exterior, and construction bays are non-rotating. Lewis One is compared to the Bernal Sphere space colony designed in the 1970’s. Lewis One is visualized using state of the art computer graphics hardware and software to produce a three dimensional, animated, lighted, shaded, texture mapped surface model. One may interactively ‘fly’ outside and inside the structure to examine features of interest. Interactively controlled planar cutaways at any location and/or orientation are available. Visualization provides insight into, and feedback on, the design to drive improvements and communicate design concepts.

Ethical Hacking Paper Full

Abstract: The explosive growth of the Internet has brought many good things: electronic commerce, easy access to vast stores of reference material, collaborative computing, e-mail, and new avenues for advertising and information distribution, to name a few. As with most technological advances, there is also a dark side: criminal hackers. Governments, companies, and private citizens around the world are anxious to be a part of this revolution, but they are afraid that some hacker will break into their Web server and replace their logo with pornography, read their e-mail, steal their credit card number from an on-line shopping site, or implant software that will secretly transmit their organization's secrets to the open Internet. With these concerns and others, the ethical hacker can help. This paper describes ethical hackers: their skills, their attitudes, and how they go about helping their customers find and plug up security holes. The ethical hacking process is explained, along with many of the problems that the Global Security Analysis Lab has seen during its early years of ethical hacking for IBM clients.

Matrix Converter-Based Unified Power-Flow Controllers: Advanced Direct Power Control Method

Abstract—This paper presents a direct power control (DPC) for three-phase matrix converters operating as unified power flow controllers (UPFCs). Matrix converters (MCs) allow the direct ac/ac power conversion without dc energy storage links; therefore, the MC-based UPFC (MC-UPFC) has reduced volume and cost, reduced capacitor power losses, together with higher reliability. Theoretical principles of direct power control (DPC) based on sliding mode control techniques are established for an MC-UPFC dynamic model including the input filter. As a result, line active and reactive power, together with ac supply reactive power, can be directly controlled by selecting an appropriate matrix converter switching state guaranteeing good steady-state and dynamic responses. Experimental results of DPC controllers for MC-UPFC show decoupled active and reactive power control, zero steady-state tracking error, and fast response times. Compared to an MC-UPFC using active and reactive power linear controllers based on a modified Venturini high-frequency PWM modulator, the experimental results of the advanced DPC-MC guarantee faster responses without overshoot and no steady-state error, presenting no cross-coupling in dynamic and steady-state responses.

Index Terms—Direct power control (DPC), matrix converter (MC), unified power-flow controller (UPFC).

DC/DC Boost Converter Functionality in a Three-Phase Indirect Matrix Converter

Abstract—An indirect matrix converter (IMC) connected with two input power sources is proposed: a gasoline generator as the main ac power supply and batteries as the secondary power source.
The IMC is small in size because of having a dc-link part without an electrolytic capacitor. The dc-link part is utilized by connection with a boost-up chopper with batteries as a secondary input power source. Furthermore, the chopper connects to the neutral point of the motor and utilizes the leakage inductance of the motor as a reactor component. The proposed technique successfully further
reduce the size of the converter by removing the boost reactor in the boost converter stage. The proposed converter is simulated and experimentally validated using a 750-W prototype and an induction motor driven with V/f control. The total harmonic distortion of the input and output currents are 4% and 3.7%, respectively, and the efficiency is 96%.

Index Terms—Boost-up chopper, leakage inductance, neutral point of a motor, three-phase ac/ac converter, zero-vector switching.

SMES Based Excitation System for Doubly-Fed Induction Generator in Wind Power Application

Paper Presentation on SMES Based Excitation System for Doubly-Fed Induction Generator in Wind Power Application (seminar paper full)
Abstract—This paper proposes a Superconducting Magnetic Energy Storage (SMES) based excitation system for doubly-fed induction generator (DFIG) used in wind power generation. The excitation system is composed of the rotor-side converter, the grid-side converter, the dc chopper and the superconducting magnet. The superconducting magnet is connected with the dc side of the two converters, which can handle the active power transfer with the rotor of DFIG and the power grid independently. Utilizing the characteristic of high efficient energy storage and quick response of
superconducting magnet, the system can be utilized to level the wind power fluctuation, alleviate the influence on power quality, and improve fault ride-through capability for the grid-connected
wind farms. According to the system control objective, the system can contribute to the stability and reliability of the wind power grid-connected system. Using MATLAB SIMULINK, the model of
the SMES based excitation system for DFIG is established, and the simulation tests are performed to evaluate the system performance.
Index Terms—Doubly-fed induction generator (DFIG), superconducting magnet, superconducting magnet energy storage (SMES), wind power generation.

SMES Strategy to Minimize Frequency Fluctuations of Wind Generator paper

Paper Presentation on SMES Strategy to Minimize Frequency Fluctuations of Wind Generator System (seminar paper full)
Abstract—Due to random variations of wind speed, output power of wind generator fluctuates randomly, and consequently fluctuations of power system frequency occur. These frequency fluctuations pose serious problems on the system, for example, lamp flicker and inaccuracy in the timing devices. Therefore, minimization of fluctuations of power system frequency is very
important from the viewpoint of power system security. This paper proposes an SMES (Superconducting Magnetic Energy Storage) strategy for minimization of frequency fluctuations of grid-connected wind generator system. A multi-machine power system consisting of hydroelectric generators, diesel generators and a fixed speed wind generator is considered. The performance of SMES is evaluated in detail considering different load demands and energy capacities of SMES.
Simulation results demonstrate that the proposed SMES is a very effective means of minimization of frequency fluctuations of power system including wind generator.

Transient Stability Enhancement of Wind Generator using SMES paper

Paper Presentation on Transient Stability Enhancement of Wind Generator Using Superconducting Magnetic Energy Storage Unit (seminar paper full)
Abstract—This paper proposes a robust controller for superconducting magnetic energy storage (SMES) unit to stabilize a grid connected wind generator system. In the proposed controller, both SMES active and reactive powers are controlled to decrease the fluctuations of output power and terminal voltage of the wind generator during abnormal conditions. In particular, the SMES controller is designed to enhance the system damping performance and robustness against transient disturbance. The power conversion system (PCS) of SMES unit used in this paper is composed of a sinusoidal PWM (Pulse Width Modulation) voltage source converter (VSC) and a two-quadrant DC-DC chopper using insulated-gate-bipolar-transistors (IGBT). Simulation results demonstrate that the proposed SMES controller is very effective for stabilizing wind generator as well as the entire power
system. The effectiveness of the proposed system is verified by simulation analyses using PSCAD/EMTDC.

Abstract—Power quality has become an important factor in power systems, for consumer and household appliances with proliferation of various electric/ electronic equipment and computer systems. The main causes of a poor power quality are harmonic currents, poor power factor, supply voltage variations, etc. In recent years the demand for the quality of electric power has been
increased rapidly. Power quality problems have received a great attention nowadays because of their impacts on both utilities and customers. Voltage sag, swell, momentary interruption, under voltages, over voltages, noise and harmonics are the most common power quality disturbances.
This paper proposes a new  connection for a unified power quality conditioner (UPQC) to improve the power quality of two feeders in a distribution system. This paper illustrates how UPQC can improve the power quality by mitigating all these PQ disturbances. The proposed configuration of the UPQC is developed and verified for various Power Quality disturbances by simulating the model using PSCAD/EMTDC. The disturbances considered here are according to IEC Electromagnetic Compatibility Standards.

Keywords: Powerquality, UPQC, PQ disturbances, Electromagnetic Compatibility (EMC) Standards.
