Synthesis of Arbitrary Antenna Arrays
(Indian Institute of Science, 2005-10-27)
Design of antenna arrays for present day requirements has to take into account both mechanical and electrical aspects. Mechanical aspects demand the antennas to have low profile, non-protruding structures, structures ...
Performance Analysis Of A Variation Of The Distributed Queueing Access Protocol
(Indian Institute of Science, 2005-10-04)
"A distributed queueing Medium Access Control (MAC) protocol is used in Distributed Queue Dual Bus (DQDB) networks. A modified version of the MAC protocol was proposed by R.R. Pillai and U. Mukherji in an attempt to overcome ...
Speech Encryption Using Wavelet Packets
(Indian Institute of Science, 2005-10-07)
The aim of speech scrambling algorithms is to transform clear speech into an unintelligible signal so that it is difficult to decrypt it in the absence of the key.
Most of the existing speech scrambling algorithms tend ...
Why only two ears? Some indicators from the study of source separation using two sensors
(Indian Institute of Science, 2005-02-10)
In this thesis we develop algorithms for estimating broadband source signals from a mixture using only two sensors. This is motivated by what is known in the literature as cocktail party effect, the ability of human beings ...
Clustering For Designing Error Correcting Codes
(Indian Institute of Science, 2005-02-11)
In this thesis we address the problem of designing codes for specific applications. To do so we make use of the relationship between clusters and codes. Designing a block code over any finite dimensional space may be thought ...
A Hybrid Knowledge-Based System for Process Plant Fault Diagnosis
(Indian Institute of Science, 2005-03-11)
Knowledge-Based Systems (KBSs) represent a relatively new programming approach and methodology that has evolved and is still evolving as an important sub-area of Artificial Intelligence (AI) research. The most prevalent ...
Task Scheduling Technlques for Distrlbuted/Parallel Processing Systems
(Indian Institute of Science, 2005-01-26)
This dissertation discusses the principles, techniques and approaches adopted in the design of task scheduling algorithms for Distributed Parallel Processing Computer Systems (DPCSs) connected with network of front-end ...
Dynamic Dealy Compensation and Synchronisation Services for Continuous Media Streams
(Indian Institute of Science, 2005-09-14)
Multimedia' nature of an application refers to the presence of several media streams in parallel. Whether it is receiving real-time data or retrieving stored data, there exists an end-to-end delay in data transfer from ...
Modelling And Analysis Of Event Message Flows In Distributed Discrete Event Simulators Of Queueing Networks
(Indian Institute of Science, 2005-10-03)
Distributed Discrete Event Simulation (DDES) has received much attention in recent years, owing to the fact that uniprocessor based serial simulations may require excessive amount of simulation time and computational ...
