Reconstruction of 1-D signal from the undersampled version
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
In the present era of information the data transmission and data storage are done as per the sampling theorem. The sampling theorem states that a bandlimited signal has to be sampled at a rate two times the maximum frequency ...
HDL implementation of associative memory based instruction predictor for power reduction
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Now a days, power consumption in digital integrated circuits/systems is a major issue. The goal here is to reduce power consumption, by assuming the circuit is divided in different power consuming modules, observing their ...
Vowel landmark detection for speech recognition
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Landmarks are the time instants in a speech utterance which marks the important events such as vowels, glides and consonants. This thesis proposes a novel Vowel Landmark Detection (VLD) algorithm to locate vowel landmarks ...
Acoustic analysis of musical pillars of vitthala temple, Hampi
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
This thesis is a systematic investigation on the acoustics of musical pillars of Vitthala temple at Hampi, India. The columns of different pillars produce sounds of different musical instruments (in particular, instruments ...
HDL implementation and study of ANN architecture mapping onto multiple processing nodes
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
A general methodology has implemented on several Processing Nodes (PN) to be connected to form an Artificial Neural Network (ANN). This design has multiple Activation functions on the same architecture which makes it ...
Characterization of NON-ISA factual sentences in english
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Availability to reason for extraction of knowledge has made Ontology Learning subject of intensive study for past couple of years. With the scaling of the domain, time taken to manually conceptualize the domain knowledge ...
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 ...
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 ...

Pose estimation from one conic correspondence
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
In this thesis we attempt to solve the problem of camera pose estimation from one conic correspondence by exploiting the epipolar geometry. For this we make two important assumptions which simplify the geometry further. ...
