Modelling and short term forecasting of flash floods in an urban environment
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
Rapid urbanization, climate change and extreme rainfall has resulted in a growingnumber of cases of urban flash floods. It is important to predict the occurrenceof flood so that the aftermath of the flood can be minimized. ...
The Study of Vertex Coloring Algorithms Using Heuristic Approaches
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
Graph vertex coloring is one of the most studied NP-complete optimization problem (READ, 1972) [2]. The problem is that; given a graph G, determine the number of colors required to color G, so that no two adjacent vertices ...
The Study of Cycles in 2-connected Graphs Specifically Odd Graphs
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
Counting the number of cycles in an undirected graph is a classical problemwhich
is known to be intractable and so research on this problem typically focuses on approximation
algorithms, special cases, heuristics and some ...
Phase-based Features for Replay Spoof Detection System
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
Automatic Speaker Verification (ASV) system is used to verify the claimed identity of a speaker based on speech samples with the help of machines. The spoofing attacks increased due to significant technological advances ...
Design and Implementation of Low Power Superscalar Processors
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
This thesis presents an 8-stage low power Superscalar processor. Since there has come an upper limit on the frequency that a single core inline processor can provide, to improve performance we need to exploit concepts like ...
Generative Adversarial Networks for Speech Technology Applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
The deep learning renaissance has enabled the machines to understand the observed data in terms of a hierarchy of representations. This allows the machines to learn complicated nonlinear relationships between the representative ...
Performance analysis of next generation graphene interconnects
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
The state-of-the-art development and subsequent miniaturization of technologiesin e-systems such as computers and digital communication systems, have led todensely and compactly placement of devices and interconnects in ...
Assessing quality of use case specifications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
Use case modeling is one of the popular documentation strategies meant to describe the functional requirements of a software system. However, due to the use of some Natural Language (NL) text issues, such as ambiguity, ...
Imbalanced bioassay data classification for drug discovery
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
All the methods developed for pattern recognition will show inferior performance
if the dataset presented to it is imbalanced, i.e. if the samples belonging to one
class are much more in number compared to the samples ...
Novel circular fractal antenna array
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
Traditional antennas work well only for one resonant frequency and using multiple antennas for different frequencies is a complex task, therefore multiband circular fractal antenna was designed which have a small size and ...
