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 ...

There has been a great demand in a Computer Aided Design (CAD) tool with a capability of design and analysis of gigahertz system having active Monolithic Microwave
Secure and efficient dealing with node capture attack in wireless sensor networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2017)
Wireless Sensor Networks (WSN) have found enormous applications in various areas of day-to-day life such as in health-care, battle-field surveillance and disaster management. The communication amongst the sensor nodes ...
Wavelets and filter banks: novel approaches for real and complex-valued transform designs
(Dhirubhai Ambani Institute of Information and Communication Technology, 2017)
Processing of natural images stored as 2-D discrete signals is an inevitable task in almost all areas of image processing. In order to have the desired processing results, directional image representation can be considered ...
Novel techniques for auto-inpainting in heritage reconstruction
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
Digital reconstruction of ruined historic monuments and heritage sites can help in visualizing how these may have existed in the past. Also, such a process requires no physical alteration to the existing monuments. This ...

Dense disparity estimation using stereo images
(Dhirubhai Ambani Institute of Information and Communication Technology, 2017)
"“Stereo vision” refers to the ability to infer information on the three-dimensional (3D) structure and distance/depth of a scene using two images captured from different view-points. It imitates one of the tasks performed ...
Crying for a reason : a signal processing based approach for infant cry analysis and classification
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
The present work in this thesis is directed towards understanding the reason of crying of an infant using signal processing approaches. Infant cry analysis and classification is a non-invasive method of analyzing the infant ...
Efficient, revocable and auditable access over encrypted cloud data
(Dhirubhai Ambani Institute of Information and Communication Technology, 2017)
Cloud data outsourcing services can potentially help reduce the IT budget of organizations. However, they pose significant risks to the security and privacy of the data as the data is outsourced to untrusted third-party ...
