(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Cloud computing provides a computing platform for the users to meet their demands in an efficient way. Virtualization technologies are used in the clouds to aid the efficient usage of hardware. Virtual machines are utilized ...
Multiband cooperative spectrum sensing in cognitive radio networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Spectrum Sensing forms one of the most important functions of Cognitive Radio operation. Energy detection is a less complex spectrum sensing technique which does not need knowledge of Primary User (PU) signal. An Energy ...
Multipath verification defense against SSL stripping attack
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
SSL stripping attack is a man- in- the- middle attack which poses a serious threat to the security of secure socket layer protocol. In SSL stripping attack the attacker has ability to downgrade security of SSL protected ...
Objective evaluation of speech quality of text-to-speech (TTS) synthesis systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Since the use of Text-to-Speech (TTS) technology is increasing, there is a high demand of TTS system that can produce natural and intelligible voice in any environments. In order to improve speech synthesis system, synthesized ...
Person recognition using humming, singing and speech
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
In this thesis, person recognition system is designed for three different speech-related biometric signals, i.e., humming, singing and normal speech. As humming is nasalised sound, we have approached Mel filterbank-based ...

(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Phase Locked Loop (PLL) plays a vital role in electronic applications, microprocessors, communication & computers. Recent advancement in wireless technologies & CMOS technologies show many advantages for medical diagnostic ...
Phonetic segmentation: unsupervised approach
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Phonetic segmentation can find its potential application for Automatic Speech Recognition (ASR) and Text-to-Speech (TTS) Synthesis systems. In this thesis, we propose use of different spectral features viz., Mel Frequency ...
RF power harvesting and enhancing throughput in a optical link based sensor network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Energy is one of the most important constraint inWireless Sensor Network (WSN), all the existing protocols, architectures revolve around the power plane. As the sensor network scale, their feasibility of implementation ...
RESTful web service integration
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Internet is providing the platform for accessing different kinds of services in a distributed and heterogeneous environment. Software components are available on Internet in the form of Web Services. Service Oriented ...
SLAM (Self localization and mapping)
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
A fundamental competence of any mobile robot system is the ability to remain localized while operating in an environment. For unknown/partially known environments there is a need to combine localization with automatic ...
