Low complexity 2-level (FFT-GOERTZEL) spectrum sensing method for cognitive radio
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Energy detection in frequency domain is a preferred technique for the spectrum sensing and
the accuracy of frequency estimation depends on the Discrete Fourier Transform (DFT) size.
Instead of computing full length (N) ...
Modeling and detecting attacks against key agreement protocols
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Key agreement protocols establish a shared secret key between two or more communicating
parties willing to exchange data over insecure channels using symmetric key cryptography.
Based on the number of members involved ...
Multiresolution fusion using compressive sensing and graph cuts
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Multiresolution fusion refers to the enhancement of low spatial resolution (LR) of Multispectral
(MS) images to that of Panchromatic (Pan ) image without compro- mising on the spectral
details. Many of the present day ...
Novel 7T SRAM cell design for low power cache applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Scaling in integrated circuit technology directly paves way to increased package density,
thereby increasing onchip power. With continuous scaling, low power design techniques
results in efficient use of silicon die. ...
Person identification from their hum with inter-session variability compensation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
In this thesis, design of person recognition system from their hum is discussed. The emphasis
is given to the inter-session variability of the recognition system. Standard database is not
available for the inter-session ...
Person identification using face and speech
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
In this thesis, we present a multimodal biometric system using face and speech features.
Multimodal biometrics system uses two or more intrinsic physical or behaviour traits to
provide better recognition rate than unimodal ...
Reduction of power using innovative Clock Gating and Multi Vth techniques in digital design
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Low power is one of the most important issues in today’s ASIC (Application Specific
Integrated Circuit) design. As the transistors scale down, power density becomes high and
there is immediate need of reduction in power. ...
Reducing climate vulnerabilities of cotton farmers in Banaskantha (North Gujarat)
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
The multiple regression models is used to analyze the effect of frequently changing weather,
like wide uctuation in monsoon rains, extremes in temperature, etc. on the cotton crop in
North Gujarat Region. The study is ...
Semantic web data management: data partitioning and query execution
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Semantic Web database is an RDF database. Due to increased use of Semantic Web in real
life applications, we can find immense growth in the use of RDF databases. As there is a
tremendous increase in RDF data, efficient ...
SPARQLGen: generation of SPARQL from pseudo BGP
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
SPARQL is the querying language and communication protocol for communicating with RDF
data sources. SPARQL query requires knowledge of URIs of bound values in the triple
patterns and ontological schema used by dataset. ...
