Abstract:
Health insurance has become a necessity for the common man,
next to food, clothing and shelter. The financing of health expense is either catastrophic or sometimes even frequently contracted illnesses, is a
major cause of mental agony for the common man. The cost of care may
sometimes result in the complete erosion of the family savings or may
even lead to indebtedness as many studies on causes of rural
indebtedness bear testimony (Jayalakshmi, 2006). A suitable cover by way
of health insurance is all that is required to cope with such situations.
Health care insurance rightly provides the mechanism for both
individuals and families to mitigate the financial burden of medical
expenses in the present context. Hence a well designed affordable health
insurance policy is the need of the hour.Therefore, it is very significant to study the extent to which the
beneficiaries in Kerala make use of the benefits provided by a social health
insurance scheme like RSBY-CHIS. Based on the above pertinent points, this
study assumes national relevance even though the geographical area of the
study is limited to two districts of Kerala. The findings of the study will bring
forth valuable inputs on the services availed by the beneficiaries of RSBYCHIS
and take appropriate measures to improve the effectiveness of the scheme
whereby maximum quality benefit could be availed by the poorest of the poor
and develop the scheme as a real dawn of the new era of health for them

Abstract:
This thesis addresses one of the emerging topics in Sonar Signal Processing.,viz.the implementation of a target classifier for the noise sources in the ocean, as the operator assisted classification turns out to be tedious,laborious and time consuming.In the work reported in this thesis,various judiciously chosen components of the feature vector are used for realizing the newly proposed Hierarchical Target Trimming Model.The performance of the proposed classifier has been compared with the Euclidean distance and Fuzzy K-Nearest Neighbour Model classifiers and is found to have better success rates.The procedures for generating the Target Feature Record or the Feature vector from the spectral,cepstral and bispectral features have also been suggested.The Feature vector ,so generated from the noise data waveform is compared with the feature vectors available in the knowledge base and the most matching pattern is identified,for the purpose of target classification.In an attempt to improve the success rate of the Feature Vector based classifier,the proposed system has been augmented with the HMM based Classifier.Institutions where both the classifier decisions disagree,a contention resolving mechanism built around the DUET algorithm has been suggested.

Abstract:
Among the large number of photothcrmal techniques available, photoacoustics
assumes a very significant place because of its essential simplicity and the variety of
applications it finds in science and technology. The photoacoustic (PA) effect is the
generation of an acoustic signal when a sample, kept inside an enclosed volume, is
irradiated by an intensity modulated beam of radiation. The radiation absorbed by the
sample is converted into thermal waves by nonradiative de-excitation processes. The
propagating thermal waves cause a corresponding expansion and contraction of the
gas medium surrounding the sample, which in tum can be detected as sound waves by
a sensitive microphone. These sound waves have the same frequency as the initial
modulation frequency of light. Lock-in detection method enables one to have a
sufficiently high signal to noise ratio for the detected signal. The PA signal amplitude
depends on the optical absorption coefficient of the sample and its thermal properties.
The PA signal phase is a function of the thermal diffusivity of the sample.Measurement of the PA amplitude and phase enables one to get valuable information
about the thermal and optical properties of the sample.
Since the PA signal depends on the optical and thennal properties of the
sample, their variation will get reflected in the PA signal. Therefore, if the PA signal
is collected from various points on a sample surface it will give a profile of the
variations in the optical/thennal properties across the sample surface. Since the optical
and thermal properties are affected by the presence of defects, interfaces, change of
material etc. these will get reflected in the PA signal. By varying the modulation
frequency, we can get information about the subsurface features also. This is the basic
principle of PA imaging or PA depth profiling. It is a quickly expanding field with
potential applications in thin film technology, chemical engineering, biology, medical
diagnosis etc. Since it is a non-destructive method, PA imaging has added advantages
over some of the other imaging techniques. A major part of the work presented in this
thesis is concemed with the development of a PA imaging setup that can be used to
detect the presence of surface and subsmface defects in solid samples.Determination of thermal transport properties such as thermal diffusivity,
effusivity, conductivity and heat capacity of materials is another application of
photothennal effect. There are various methods, depending on the nature of the
sample, to determine these properties. However, there are only a few methods
developed to determine all these properties simultaneously. Even though a few
techniques to determine the above thermal properties individually for a coating can be
found in literature, no technique is available for the simultaneous measurement of
these parameters for a coating. We have developed a scanning photoacoustic technique that can be used to determine all the above thermal transport properties
simultaneously in the case of opaque coatings such as paints. Another work that we
have presented in this thesis is the determination of thermal effusivity of many bulk
solids by a scanning photoacoustic technique. This is one of the very few methods
developed to determine thermal effiisivity directly.

Abstract:
In the absence of entry barrier or regulatory restrictions, Non Banking Financial
Companies frantically grew and accessed the public deposit without any
regulatory control. The deposit of NBFCs grew from Rs. 41.9 crore in 1971 to
53116.0 crore in 1997. This growth was the result of a combined effect of
increase in the number of NBFCs and increase in the amount of deposits. The
deposits amazed as above was invested in various assets especially that in
motor vehicles by these asset financing NBFCs. Various tactics were adopted
by these NBFCs and their agents for recovering the receivable outstanding from
such assets. Both central government and RBI were concerned about the
protection of depositors‘ interest and various committees were set up to frame a
comprehensive regulation for the functioning of these NBFCs.

Abstract:
Microarray data analysis is one of data mining tool which is used to
extract meaningful information hidden in biological data. One of the major
focuses on microarray data analysis is the reconstruction of gene regulatory
network that may be used to provide a broader understanding on the
functioning of complex cellular systems. Since cancer is a genetic disease
arising from the abnormal gene function, the identification of cancerous genes
and the regulatory pathways they control will provide a better platform for
understanding the tumor formation and development. The major focus of this
thesis is to understand the regulation of genes responsible for the development
of cancer, particularly colorectal cancer by analyzing the microarray
expression data.
In this thesis, four computational algorithms namely fuzzy logic
algorithm, modified genetic algorithm, dynamic neural fuzzy network and
Takagi Sugeno Kang-type recurrent neural fuzzy network are used to
extract cancer specific gene regulatory network from plasma RNA dataset
of colorectal cancer patients. Plasma RNA is highly attractive for cancer
analysis since it requires a collection of small amount of blood and it can be
obtained at any time in repetitive fashion allowing the analysis of disease
progression and treatment response.

Abstract:
Public undertakings have been assigned a significant role to play in the systematic socio-economic development of India. My interest in the subject was kindled while I was doing my Masters Diploma in Public Administration at the Indian Institute of Public Administration, New Delhi during 1960-61. It was further strengthened by my teaching of the subject in different courses offered by me at the School of Management Studies and in several programmes organised by various voluntary and training organisations like the Institute of Management in Government, Trivandrum, Centre for Management Development, Trivandrum, etc. The several years in which I served as a member of the faculty in the School of Management Studies, University of Cochin,gave me the opportunity to come into close contact with different public sector concerns and their managers at various levels. This rich opportunity gave me a better insight into the problems faced by these concerns. The present study is a result of the interest so developed.
