(Indian Institute of Science, 2006-01-18)Presented in this thesis are the following theoretical investigations carried out on the non-invasive microwave hyperthermia of malignant tumours in the human body: Fundamental concepts of electromagnetic wave ... -
Electrical Properties Of Diamond Like Carbon Films In Metal-Carbon-Silicon (MCS) Structure
(Indian Institute of Science, 2006-01-18)Amorphous carbon film with Diamond like properties is the subject of intense interest in the past one and half decade. The unusual properties of these diamond like carbon films arise from the preponderance of SP3 tetrahedral ... -
Hyperplane Partitioning : An Approach To Global Data Partitioning For Distributed Memory Machines
(Indian Institute of Science, 2005-12-07)Automatic Global Data Partitioning for Distributed Memory Machines (DMMs) is a difficult problem. Distributed memory machines are scalable, but since the memory is distributed across processors, the scheme of placement ... -
An Adaptive Recompilation Framework For Rotor And Architectural Support For Online Program Instrumentation
(Indian Institute of Science, 2005-12-07)Although runtime systems and the dynamic compilation model have revolutionized the process of application development and deployment, the associated performance overheads continue to be a cause for concern and much research. ... -
Automatic Data Partitioning By Hierarchical Genetic Search
(Indian Institute of Science, 2005-12-07)The introduction of languages like High Performance Fortran (HPF) which allow the programmer to indicate how the arrays used in the program have to be distributed across the local memories of a multi-computer has not ... -
Language Support For Testing CORBA Based Applications
(Indian Institute of Science, 2005-12-07)Component Based Development has emerged as economical, reusable, scalable way of developing enterprise as well as embedded software applications. Testing distributed component based systems is difficult when third party ... -
Integrated Scheduling For Clustered VLIW Processors
(Indian Institute of Science, 2005-11-25)Clustered architecture processors are preferred for embedded systems because centralized register file architectures scale poorly in terms of clock rate, chip area, and power consumption. Scheduling for clustered architectures ... -
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 ... -
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 ... -
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 ... -
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 ... -
