Formal semantic simplification of Wh-query in english
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
The problem of Natural Language Query Formalization is to understand the semantics of a user given query in natural language (NL) and then translating the Query into a formal language (FL) such that the FL semantic ...
Lifetime analysis of wireless sensor nodes using queuing models
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Prolonging the lifetime of wireless sensor networks (WSN) is one of the key issues for wireless sensor network applications. For increasing the lifetime of network, each node should conserve its energy. Sensor nodes consume ...
Channel estimation in OFDM systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Orthogonal frequency division multiplexing (OFDM) is not a new concept, but its receiver design has constant improvement. OFDM uses available spectrum efficiently and the system provides high data rates. Many standards ...
Depth from defocus
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
With the recent innovations in 3D technology accurate estimation of depth is very fascinating and challenging problem. In this thesis, a depth estimation algorithm, utilizing Singular Value Decomposition to compute orthogonal ...
Asynchronous analog to digital converter

Investigation on spatial arrangement of transceiver arrays in free space optical communication system
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Free space optical communication (FSO) is a line of sight communication that uses lasers (as transmitter) and photo detectors (as receiver) to provide communication between two points. FSO have come about in need for greater ...
Multiresolution fusion of satellite images and super-resolution of hyper-spectral images
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
This thesis presents a model based approach for multi-resolution fusion of the satellite images. Given a high resolution panchromatic (Pan) image and a low spatial but high spectral resolution multi spectral (MS) image ...
Post-processing of speech signal for prosody modification and improvement
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
The basic task of a text-to-speech (TTS) synthesis system is to obtain the correct synthetic speech signal with the help of machines corresponding to the given input text. However, the main difficulty with the TTS system ...
