Performance analysis and comparison of community based node co-operation in mobile social networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
In wireless ad-hoc networks, communication is done mainly through intermediate nodes or relay nodes. The mobile nodes in ad-hoc network have limited energy, so the intermediate nodes or relay nodes do not always co-operate ...
Performance improvement of an out of order processor by decreasing branch mispredictions
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Superscalar processors are most common in hardware systems ranging from servers to small low power hand held devices. High performance Superscalar processors execute a large number of instructions to exploit Instruction ...
Query optimization of object oriented database through compilation and execution
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Database is central to many applications like a website, app, software or any business applications to store the data in various formats which can be retrieved efficiently and conveniently as and when required by the ...
Retrieval of legal documents using query expansion
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Structure of query by a lawyer and a layman is different. Legal content in the layman’s query is very less. Thus pre-processing of these queries is required for better retrieval performance.
In this thesis, we used ...
Secure SQL with access control for database as a service model
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Rapid growth of internet and networking technology emerges "Software as a service model". In this model, application service providers (ASP) provides each functionality of software over internet. ASP provides access of ...
Spectrum sensing in cognitive radio networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
In this thesis, we consider the problem of secondary users’ selection for cooperative spectrum sensing in cognitive radio networks. We assume that the secondary users involved in sensing transmit their spectral energy ...
Structure indexed vertical partition and query execution for RDF data
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
The Semantic Web is an effort by the W3C to enable integration and sharing of data across different applications and organizations. Tremendous growth of organizations and applications across World Wide Web requires the ...
Tikitaka based attack strategy for soccer simulation 2D
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Soccer Simulation 2D has grown as a testbed for MultiAgent research over the years. As it provides a complete distributed platform for simulating the algorithm proposed. I have also used the same platform for my ...
Vocal tract length normalization for automatic speech recognition
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Various factors affect the performance of Automatic Speech Recognition (ASR) systems. In this thesis, speaker differences due to variations in vocal tract length (VTL) are taken into account. Vocal Tract Length Normalization ...
Design and analysis of novel receiver front-end sub-systems in Ku-band for satellite applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
A novel receiver front-end; Low Noise Amplifier (LNA), mixer and Local Oscillator (LO); is designed and analyzed in Ku-band. Different design aspects of the subsystems along with the trade-offs and improvements are presented. ...
