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 ...
Chalo bajaar jaiye : Ahmedabad through markets
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
The idea of this project was to bring awareness among the tourists who are going to visit the city or the migrants who are going to shift to the city or the locals about a historic city Ahmedabad through a different dimension ...
On insider attack in distributed file systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
Due to heavy use of internet, mobiles, sensors etc. Data is growing rapidly day-by-day. However traditional database systems fail to store such a huge semi structured or unstructured data which raises the need for distributed ...
Hybrid partitioning and distribution of RDF data
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
RDF is a standard model by W3C specifically designed for data interchange on the web. RDF was established and used for the development of the semantic web. However, nowadays RDF data is being used for diverse domains and ...
Adaptive techniques to improve the efficiency of GaN based SSPAs (up to C Band) for geo synchronous satellites
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
In this thesis, various adaptive techniques to improve the efficiency of Solid State Power Amplifier (SSPA) for Geo Synchronous Satellite are presented. The Microwave Power Amplifiers (MPAs) being the most important ...
