Microwave imaging of a 36-cell human body by moment method formulation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Estimation of a complex permittivity is achieved using the moment method formulation of electric field integral equation. In addition to numerical results for three dimensional biological bodies, thesis also describes ...
Data aware hybrid partitioning technique and query execution for RDF data
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Storage of huge semantic web data using relational techniques has been an important research issue in web databases. Semantic web data is Resource Description Framework (RDF) data. Triple store technique is very inefficient ...
Precoder design for beamforming in K-User MIMO interference chennel
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Beamforming in MIMO wireless networks, is a techniques used for mitigating interference and achieve the best possible throughput. Accurate channel state information is essential for efficient design of beamforming vectors ...
Theyyam: the dancing colours of caste focus: north Malabar (Kerala)
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
The objective of the project is to explore something which is unseen, exploring the changes in the social hierarchy by revolutions in Kerala. Theyyam, the ritual form of worship of North Malabar(district of Kannur and ...
Channel estimation and soft OSIC detection in coherent MIMO-OFDM systems using QRD techniques(802.16m)
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Next generation mobile systems will use multiple antennas at the transmitter and receiver to achieve higher capacity and diversity gain at high speeds. By transmitting through multiple transmitting and receiving antennas, ...
Adaptive channel estimation and loading for OFDM based two-way relay systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
In this thesis we introduce a low complexity Recursive Least Square (RLS) based Orthogonal Frequency Division Multiplexing (OFDM) channel estimation for two-way relay system. Using the estimate of the channel, a bit and ...
Coordinated adaptive power management (CAPM) technique for sensor network nodes
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Small size of wireless sensor nodes limit the size of the battery supported on it which directly limits the capacity of the battery and lifetime of the sensor nodes. Though energy scavenging is one of the solutions, it is ...
Broadband microstrip antennas with switchable polarizations
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Microstrip antenna consists of a patch of metallization on grounded substrate. These are low profile, lightweight antennas, most suitable for aerospace and mobile application. They are replacing many conventional antennas ...
Algebraic approach to Nash equilibria for finite normal form games
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
In this work we consider methods for computing Nash equilibria of finite normal form games that emphasize use of polynomial algebra. Nash equilibria of a game can be characterized as solutions to a system of polynomial ...
New techniques for spatial resolution enhancement of hyperspectral images
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Vision plays a central role for human perception and interpretation of the world. With the beginning of the space age during late 1950s presented opportunities for remote sensing of earth resources [1]. Multispectral sensors ...
