Electric Double Layer Capacitors (EDLC)


INTRODUCTION
Electric Double Layer Capacitors (EDLC) are also called super capacitors or ultra capacitors. They store energy in the form of static charges. EDLC resembles the ordinary capacitors but having high energy density. EDLC have very low working voltage ,and are used in hybrid vehicles. EDLC Ëœs are rated from Farads to Kilo Farad ranges
HISTORY & PRESENT
Electric double layer effect was first noticed by General Electric engineers in 1957. B ....etc

DNSSEC : A Protocol towards securing

Abstract: Unlike spam, worms, viruses, and phishing”all of which confront end users directly” infrastructure attacks occur outside their normal frame of reference and control. But attacks on the Domain Name System (DNS), an engine of the Internet infrastructure, appear to be increasing in length and severity, affecting DNS information associated with financial services institutions, Internet service providers, and major corporations in the travel, health, technology, and media/ entertainment ....etc

Patterns, Symmetry and Symmetry Breaking

Software Design pattern capture tried and successful design solutions. Among different views on design patterns is that they are created to compensate for the design shortfalls in programming languages that is, design patterns are needed when programming languages cannot do the job in straightforward way. There is a casual relationship between language features and design patterns and that relationship is couched in a more fundamental relationship between symmetries and broken symmetries. This paper ....etc

Abstract
Molecular electronics (sometimes called moletronics) is an interdisciplinary theme that spans physics, chemistry, and materials science. The unifying feature of this area is the use of molecular building blocks for the fabrication of electronic components, both passive (e.g. resistive wires) and active (e.g. transistors). The concept of molecular electronics has aroused much excitement both in science fiction and among scientists due to the prospect of size reduction in electronics offered by molecular-level co ....etc

ABSTRACT
In recent years, digital computer is becoming most appropriate tool to solve any engineering problem. In last two decades number of programs have been developed for computers in solving power system problems. Many of these programs deal with system load flow, short circuit currents, stability, and for control of power systems. The higher percentage of proper utility of computers in distribution systems saves engineering time and investment.
All the time the distribution engineer encounters th ....etc

This paper proposes a novel feature extractionscheme for audio fingerprinting using discretewavelet transform (DWT). The proposed schemereduces the granularity, i.e., the minimal length ofaudio, needed for identification in an audiofingerprinting system. The scheme first decomposesthe video frame into sub-bands by DWT
The proposed scheme hastwo advantages:
(1) it needs smaller fingerprintgranularity than other previous work;
(2) it is notonly reliable but also robust against various signal
degradations according to the ex ....etc

EDDY CURRENT BRAKES

EDDY CURRENT:
It is a swirling current set up in a conductor in response to a changing magnetic field.
By Lenz's law, the current swirls in such a way as to create a magnetic field opposing the change

Eddy Current Brakes
It slow an object by creating eddy currents through emi which create resistance, and in turn either heat or electricity.
Braking action is made by varying the strength of the magnetic field.
¢ A braking force is possible when electric current is passed ....etc

ABSTRACT
Hy-Wire Car is without mechanical and hydraulic linkage end engine. Instead of these it contain a fuel cell stack and a drive by wire system. It is fully automated car it is a future car. In future it will have a wide application. The problem with fuel consumption and pollution can be minimize to certain level.
