Fractal based approach for face recognition
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
An automated face recognition system is proposed in this dissertation. The system efficiently recognizes a candidate (test) image using the interdependence of the pixel that arises from the fractal compression of the image. ...
Identifying mutant hierarchies to reduce test effort in mutation testing
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Mutation testing is a fault-based testing approach. The main goal of mutation testing is to assess the quality of a test suite, and in that process, test the software. The approach asserts the absence of pre-specified ...
Identifying small world network properties in ad-hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Small World Network is a densely connected network with low degree of separation. These types of networks have high clustering property like regular network as well as have low average path length like random network. Thus, ...
Integrated receiver front-end: system level architectures and design issues for CDMA based applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
During the last decade, the world of mobile communications has experienced an enormous growth. Among the important factors has been possible by the migration from the original analog mobile phones to handsets using digital ...
Incorporation of mobility model of nodes in zone routing protocol for mobile ad hoc wireless networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Ad Hoc wireless networks are characterized by dynamically changing network topology due to relative motion of the nodes. This leads to the exchange of large number of control packets between the nodes to maintain the network ...
Issues of computational resource allocation and load balancing in cloud computing using virtualization
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
With the advent of world wide web, the life of every person has changed drastically. No one can imagine a computer without being connected to the Internet. This dependency is likely to grow in coming years with the adoption ...
Low drop-out (LDO) voltage regulator without off-chip capacitor
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Designing of Low Drop-Out Voltage Regulators (LDOs) operating without a large off-chip capacitor, having a very good transient response and maintaining the loop stability for full load current range in low supply voltage ...
Low power SRAM design
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
In the past, power dissipation was not constraining factor because of device density and operating frequency was low enough. But nowadays due to increased integration and operating frequency of integrated circuits, power ...
Low power improved full scan BIST
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Low power testing of VLSI circuits has recently become an area of concern due to yield and reliability problems. Past research on low power testing has shown that, switching activity and test time are the main factors that ...
Low power BIST architecture for fast multiplier embedded core
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
A typical core is deeply embedded in the chip of a system so that direct access to its input/output is not possible. Built in self test (BIST) structures are excellent solutions for testing embedded cores.
In this work, ...
