Microwave Imaging for Breast Cancer Detection using 3D Level Set based Optimization, FDTD Method and Method of Moments
(Dhirubhai Ambani Institute of Information and Communication Technology, 2019)
Microwave imaging is emerging as new diagnostic option for breast cancer detection because of non-ionizing nature of microwave radiation and significant contrast between dielectric properties of healthy and malignant breast ...
Peer-to-peer communication in mobile social network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
Peer-to-peer opportunistic communication between mobile devices carried by humanswithout using any infrastructure is largely unexploited. As these devices are carried byhumans, their encounter pattern depends on human ...
Design and analysis of novel receiver front-end sub-systems in Ku-band for satellite applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
A novel receiver front-end; Low Noise Amplifier (LNA), mixer and Local Oscillator (LO); is designed and analyzed in Ku-band. Different design aspects of the subsystems along with the trade-offs and improvements are presented. ...
Micro-level drought preparedness with information management and rural knowledge centres: a framework to support rural farm families
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Drought and desertification are serious problems that significantly affect hundreds of millions of people and ecosystems. When drought occurs, the farm communities are usually the first to be affected because of their heavy ...
On large scale near-independent blind source separation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
The thesis addresses Blind Source Separation (BSS) in Large Scale (LS) and near-Independent
(nI) sources scenario. The large scale in BSS imply number of unknown sources ranging from 15 to 140, so that the corresponding ...
Detection of tampering in digital images using feature based hash generation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Recent years have witnessed an exponential growth in the use of digital images due to development of high quality digital cameras and multimedia technology. Easy availability of user-friendly image editing software has ...
Bandwidth considerations in miniaturized rectangular dielectric resonator antennas: experimental validation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
In this thesis, an issue of bandwidth is considered in a rectangular dielectric resonator antenna (RDRA). Two techniques (merging of modes and stacking) of bandwidth im- provement are introduced with miniaturized resonator. ...
Multi-modal design of an intelligent transportation system
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
An Intelligent Transportation System (ITS) plays a major role in generating ne grained vehicular tra c information for city wide or larger region. The real time tra c informa-tion is used to optimize tra c movement in a ...
