Speaker recognition over VoIP network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
This thesis deals with the Automatic Speaker Recognition (ASR) system over narrowband Voice over Internet Protocol (VoIP) networks. There are several artifacts of VoIP network such as speech codec, packet loss and packet ...
Design of metamaterial
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Meta materials are artificially designed materials that exhibit very high transmission values within a frequency range. Double Negative (DNG) Meta material shows both negative permittivity and negative permeability within ...
Optical wireless sensor network design for a conducting chamber
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Now a day’s majority of the wireless sensor networks (WSNs) are based on Radio Frequency (RF) communication technology. But RF when used in an environment like that of metallic, conducting chamber exhibits large amount of ...
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 ...
QoS aware distributed service composition using agents
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Automated service composition is a way of putting together or assembling different web services to satisfy the user query or request, without using a given template. One of the ways of achieving automated service composition ...
Acyclic edge coloring of complete r-partite graphs
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
An acyclic edge coloring of a graph G is a proper edge coloring of G which has no dichromatic cycle. The minimum number of colors required to acyclically edge color graph G is called its acyclic chromatic index, denoted ...
16 bit dual threshold voltage conditional carry adder.
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
So many different circuits and different schemes are applied to make circuit faster and less power consumptive. In this thesis, 16-bit dual threshold voltage conditional carry adder, with two proposed modification for ...
Privacy preservation in vehicular ad-hoc networks (VANETs)
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Vehicular Ad-hoc Networks (VANETs) are the special application of Mobile Ad-hoc Networks (MANETs). Due to increase in the number of road accidents, VANETs provide security to road traffic by sending safety messages to other ...
HMM-based speech synthesis system (HTS) for Gujarati language.
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Hidden Markov Models (HMM) have been applied successfully to Automatic Speech Recognition (ASR) problems and are currently applied in speech synthesis applications. In this thesis, HMM-based Speech Synthesis System (HTS) ...
HDL implementation of palm associative memory
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
The objective of this paper is to implement and analyze the palm associative memory proposed by G. Palm [1]. In this paper, a design implementation of this algorithm, based on Verilog HDL (hardware description language) ...
