DWDM Technology



Wdm technology

It was first published in 1970.and by 1978 being realized in laboratory.

This term typically described it,s WAVELENGTH

In fibre optical communication wdm is a tech.which multiplex a number of optical carrier signals on to a single optical fibre by using different wavelengths(colour).


What is wdm

Data from each tdm channel is loaded on one optical frequency(wavelength)

These wavelengths are then ....etc

Contemporary Communication Systems Using MATLAB

This book has been developed as a supplement to traditional core texts in Communication Systems for instructors and students who wish to make MATLAB an integral part of their study of Communication Systems topics and concepts. The books in this new series are designed to promote students' problem solving and critical thinking skills through the use of MATLAB as a virtual laboratory. A 3.5 disk containing supporting MATLAB data files is bound into the book. This bo ....etc

Abstract
Most device drivers have one ulterior motive and one target to achieve - deliver the maximum using the minimum. No matter how stable or feature rich a device driver might be, if it cannot perform in terms of high throughput and low CPU utilization, it is as good as any other run of the mill driver.The objective of this topic is to use the thinking out of the box concept and expose techniques, which go beyond just good programming principles to get that extra edge which can put your next driver into the elite group of high perform ....etc

Fuzzy Logic and Fuzzy Sets 


History


Lotfi Zadeh, at the University of California at Berkeley, first presented fuzzy logic in the mid-1960's.

Zadeh developed fuzzy logic as a way of processing data. Instead of requiring a data element to be either a member or non-member of a set, he introduced the idea of partial set membership.

In 1974 Mamdani and Assilian used fuzzy logic to regulate a steam engine.

In 1985 researchers at Bell laboratories ....etc

developing an algorithm for data mining using clustering genetic algorithm at c++



With an enormous amount of data stored in databases and data warehouses, it is increasingly important to develop powerful tools for analysis of such data and mining interesting knowledge from it. Data mining is more than slicing and dicing of data; it is a powerful business intelligence technology that provides knowledge about unknown patterns and events from large databases. Data mining technologies have known to significantly reduce operational costs and ....etc

In this paper, fuzzy logic control is put forward in a parallel hybrid hydraulic excavator for the purposes ofbetter energy distribution and higher fuel economy. A mathematical model of parallel hybrid hydraulicexcavator is presented in detail, and the parameters of components and overall system are listed andanalyzed. The fuzzy logic controller is then designed to cope with energy distribution and management. Toachieve better equivalent fuel consumption, genetic algorithm is implemented to fine-tune the membershipfunctions. The control effects ....etc

Abstract

Prediction of an event at a time series is quite important for engineering and economy problems. Time series data mining combines the fields of time series analysis and data mining techniques. This method creates a set of methods that reveal hidden temporal patterns that are characteristic and predictive of time series events. Time series data mining examines the time series in a phase space. In this paper, a prediction algorithm using time series data mining based on fuzzy logic is proposed. Earthquake prediction has been ....etc
