Study of face recognition systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Face Recognition comes under the general area of object recognition and has attracted researchers in the pattern recognition community for the past thirty years. The significance of this area has grown rapidly largely for ...
Technique to improve revocation mechanism and enhancement of CA's services
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Public Key Cryptography [PKC] is becoming popular in the world of security because of its promising features like authentication and non-repudiation along with integrity and data confidentiality. It has been possible to ...
Tool to calculate the width and length of capacitor for switched-capacitor band pass filter
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
The switched capacitor (SC) circuits find their applications in many fields. Due to their lower size at low frequencies, higher density can be achieved compared to active RC counterparts. Still there are nonlinerarities ...

Chaotic communication system for IEEE 802.11b (WLAN)
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Today's WLAN (IEEE 802.11b) is most attractive solution for wireless data communication at higher rate. Chaotic signals, by virtue of their wideband characteristic, are natural candidates for wideband communication ...
Speech enhancement using microphone array for hands-free speech applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
This thesis addresses the problem of multi-microphone speech enhancement using GSVD (Generalized singular value decomposition) based optimal filtering algorithm. This algorithm does not require any sensitive geometric ...
Performance analysis of diffserv multicast (DSMCast) for heterogeneous receivers
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Internet is a large infrastructure that provides means for global communication. One of the biggest challenges faced in its growth and maintenance is the provision for the best Quality of Service (QoS) to the end-user ...
