HDL implementation of a node of bayesian polytree interface
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
In this thesis, we have particularly focussed on the aspects of the hardware implementation of the Bayesian inference framework within the George and Hawkins’ model. This framework is based on Judea Pearl’s belief propagation. ...
Implementation of different branch prediction schemes on FabScalar generated superscalar processor
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Performance of modern pipeline processor depends on steady flow of useful instruction for processing. Branch instruction in the program disrupts the sequential flow of instruction by presenting multiple paths through which ...
Image epitome generation and its applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
An image modeling scheme named “Epitome" was proposed by Brendan J. Frey and Nebjsa Jojic in 2002 [1]. Image epitome is a miniature, condensed version of the image. It is much smaller in the size compared to the input image ...
Numeral identification of handwritten indian languages
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Automatic Speaker Verification (ASV) systems are prone to various spoofing attacks.Spoofing is one type of technique in which fake speech signal is given tothe ASV system to get the access of that system without the ...
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 ...
