Abstract:

Digital audio broadcasting, DAB, is the most fundamental advancement in radio technology since that introduction of FM stereo radio. It gives listeners interference - free reception of CD quality sound, easy to use radios, and the potential for wider listening choice through many additional stations and services.

DAB is a reliable multi service digital broadcasting system for reception by mobile, portable and fixed receivers with a simple, non-directional antenna. It can be operated at any frequency from 30 MHz..............etc

Digital-to-Analog Analog-to-Digital
Data Handling Systems
Both data about the physical world and control signals sent to interact with the physical world are typically analog or continuously varying quantities.
In order to use the power of digital electronics, one must convert from analog to digital form on the experimental measurement end and convert from digital to analog form on the control or output end of a laboratory system.
Digital-to-Analog Conversion
When data is in binary form, the 0's and 1's may be of s..............etc

Generalized Ring Signatures-IEEE TRANSACTIONS ON DEPENDABLE AND SECURE COMPUTING, VOL. 5, NO. 3, -java

Abstract—
The concept of ring signature was first introduced by Rivest et al. in 2001. In a ring signature, instead of revealing the actual
identity of the message signer, it specifies a set of possible signers. The verifier can be convinced that the signature was indeed
generated by one of the ring members; however, the verifier is unable to tell which member actually produced the signature. In this paper,
we first propose a ..............etc

ABSTRACT
Network security has been an issue almost since computers have been networked toge ther. Since the evolution of the internet, there has been an increasing need for security systems. One important type of security software that has emerged since the evolution of the internet is intrusion detection systems. An intrusion occurs when an attacker gains unauthorized access to a valid userâ„¢s account and performs disruptive behavior while masquerading as that user. The attacker may harm the userâ„¢s account directly and can use it ..............etc
