Part of speech tagging for Gujarati text
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Part-of-speech (POS) tagging is a process of assigning the lexicon category to each
lexicons in a given natural language sentence, that best suits the definition of the lexicon as well as the context of the sentence in ...
Person recognition from their hum
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
In this thesis, design of person recognition system based on person's hum is presented. As hum is nasalized sound and LP (Linear Predication) model does not characterize nasal sounds sufficiently, our approach in this work ...
Performance evaluation of kerberos cross-realm authentication using SIMNET
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Today, the network is being implemented in such a manner that consist of geographi-
cally diverse clients and distributed as well as centralized servers. To prevent unauthorized access to system resources such as servers, ...
Practical approach for depth estimation and image restoration using defocus cue
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Reconstruction of depth from 2D images is an important research issue in computer vision. Depth from defocus (DFD) technique uses space varying blurring of an image as a cue in reconstructing the 3D structure of a scene. ...
Prolog based approach to reasoning about dynamic hierarchical key assignment schemes
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
The problem of allowing the higher level users access the information related to lower level is called Hierarchical Access Control Problem. In a hierarchical access control system, users are partitioned into a number of ...
Single ended sense amplifier for DRAM
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Today design of eDRAM is facing more challenges as the technology node is scaling
down every year. Supply Voltage is also scaling down in accordance with the technology. Thus, charge on the bitlines, to sense is also ...
Shallow parsing of Gujarati text
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Shallow parsing is the process of assigning tag to minimal, non recursive phrase
of the sentence. It is useful for many applications like question answering system,
information retrieval where there is no need of full ...
SPARQL query optimization
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Query Optimization is the process of selecting the most efficient query evaluation plan among the many strategies possible for processing a given query, especially if the query is complex. The users are not expected to ...
Super-resolution of hyperspectral images
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Hyperspectral (HS) images are used for space areal application, target detection and remote sensing application. HS images are very rich in spectral resolution but at a cost of spatial resolution. HS images generated by ...
Traffic profile measurement and traffic driven network reconfiguration
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
In multi hop ad hoc network, nodes are constrained by the power or the energy sources that are available. Efficient algorithms for saving the energy are required to manage the network in such a manner that the resources ...
