Optimal Control Problems In Communication Networks With Information Delays And Quality Of Service Constraints
(Indian Institute of Science, 2005-11-10)
In this thesis, we consider optimal control problems arising in high-speed integrated communication networks with Quality of Service (QOS) constraints. Integrated networks are expected to carry a large variety of traffic ...
Phase Sensitive Estimation Of Fluorescence Lifetime For Fiber Optic Biosensors
(Indian Institute of Science, 2005-10-04)
Fluorescence lifetime determination and allied studies find application in spectroscopy in general and fiber optic biosensors in particular. Instruments and sensors cited in literature however use open loop, intensity based ...
Estimation Of Object Shape From Scattered Field
(Indian Institute of Science, 2005-09-27)
The scattered field from an object, when illuminated with ultrasound, is useful in
the reconstruction of it's cross section - a problem broadly classified as 'tomography'. In
many situations of medical imaging, we will ...
Studies on Amorphous Silicon Thin Films Doped with Aluminium
(Indian Institute of Science, 2005-10-25)
Amorphous Silicon(a-Si) films have attracted the attention of several investigators as it is an economical material for devices. One of the problems that is addressed is the doping of these films after they are prepared.
In ...
DSP Techniques for Performance Enhancement of Digital Hearing Aid
(Indian Institute of Science, 2005-10-20)
Hearing impairment is the number one chronic disability affecting people in the world. Many people have great difficulty in understanding speech with background noise. This is especially true for a large number of elderly ...
Methods for Blind Separation of Co-Channel BPSK Signals Arriving at an Antenna Array and Their Performance Analysis
(Indian Institute of Science, 2005-06-30)
Capacity improvement of Wireless Communication Systems is a very important area of current research. The goal is to increase the number of users supported by the system per unit bandwidth allotted. One important way of ...
Diffraction Tomographic Imaging With A Circular Array
(Indian Institute of Science, 2005-06-02)
In the conventional diffraction tomography a linear array is used to receive forward scattered field. Then a standard algorithm like back propagation or Fourier domain interpolation is used for reconstruction of the object. ...
Lambda Bipolar Transistor (LBT) in Static Random Access Memory Cell
(Indian Institute of Science, 2005-07-07)
With a view to reduce the number of components in a Static Random Access Memory (SRAM) cell, the feasibility of use of Lambda Bipolar Transistor (LBT)in the bistable element of the cell has been explored under the present ...
Design and Development of a Hybrid TDMA/CDMA MAC Protocol for Multimedia Wireless Networks
(Indian Institute of Science, 2005-03-30)
A wireless local area network (WLAN) provides high bandwidth to users in a limited geographical area. This network faces certain challenges and constraints that are not imposed on their wired counterparts. They are: frequency ...
A Study On Bandpassed Speech From The Point Of Intelligibility
(Indian Institute of Science, 2005-04-06)
Speech has been the subject of interest for a very long time. Even with so much advancement in the processing techniques and in the understanding of the source of speech, it is, even today, rather difficult to generate ...
