Abstract:
Multivariate lifetime data arise in various forms including recurrent event
data when individuals are followed to observe the sequence of occurrences of a
certain type of event; correlated lifetime when an individual is followed for the
occurrence of two or more types of events, or when distinct individuals have
dependent event times. In most studies there are covariates such as treatments, group
indicators, individual characteristics, or environmental conditions, whose
relationship to lifetime is of interest. This leads to a consideration of regression
models.The well known Cox proportional hazards model and its variations, using the
marginal hazard functions employed for the analysis of multivariate survival data in
literature are not sufficient to explain the complete dependence structure of pair of
lifetimes on the covariate vector. Motivated by this, in Chapter 2, we introduced a
bivariate proportional hazards model using vector hazard function of Johnson and
Kotz (1975), in which the covariates under study have different effect on two
components of the vector hazard function. The proposed model is useful in real life
situations to study the dependence structure of pair of lifetimes on the covariate
vector . The well known partial likelihood approach is used for the estimation of
parameter vectors. We then introduced a bivariate proportional hazards model for
gap times of recurrent events in Chapter 3. The model incorporates both marginal
and joint dependence of the distribution of gap times on the covariate vector . In
many fields of application, mean residual life function is considered superior
concept than the hazard function. Motivated by this, in Chapter 4, we considered a
new semi-parametric model, bivariate proportional mean residual life time model, to
assess the relationship between mean residual life and covariates for gap time of
recurrent events. The counting process approach is used for the inference procedures of the gap time of recurrent events. In many survival studies, the distribution of
lifetime may depend on the distribution of censoring time. In Chapter 5, we
introduced a proportional hazards model for duration times and developed inference
procedures under dependent (informative) censoring. In Chapter 6, we introduced a
bivariate proportional hazards model for competing risks data under right censoring.
The asymptotic properties of the estimators of the parameters of different models
developed in previous chapters, were studied. The proposed models were applied to
various real life situations.

Abstract:
One major component of power system operation is generation
scheduling. The objective of the work is to develop efficient control strategies
to the power scheduling problems through Reinforcement Learning approaches.
The three important active power scheduling problems are Unit Commitment,
Economic Dispatch and Automatic Generation Control. Numerical solution
methods proposed for solution of power scheduling are insufficient in handling
large and complex systems. Soft Computing methods like Simulated Annealing,
Evolutionary Programming etc., are efficient in handling complex cost
functions, but find limitation in handling stochastic data existing in a practical
system. Also the learning steps are to be repeated for each load demand which
increases the computation time.Reinforcement Learning (RL) is a method of learning through
interactions with environment. The main advantage of this approach is it does
not require a precise mathematical formulation. It can learn either by interacting
with the environment or interacting with a simulation model. Several
optimization and control problems have been solved through Reinforcement
Learning approach. The application of Reinforcement Learning in the field of
Power system has been a few. The objective is to introduce and extend
Reinforcement Learning approaches for the active power scheduling problems
in an implementable manner. The main objectives can be enumerated as:(i) Evolve Reinforcement Learning based solutions to the Unit
Commitment Problem.(ii) Find suitable solution strategies through Reinforcement Learning
approach for Economic Dispatch.
(iii) Extend the Reinforcement Learning solution to Automatic Generation
Control with a different perspective.
(iv) Check the suitability of the scheduling solutions to one of the existing
power systems.First part of the thesis is concerned with the Reinforcement Learning
approach to Unit Commitment problem. Unit Commitment Problem is
formulated as a multi stage decision process. Q learning solution is developed
to obtain the optimwn commitment schedule. Method of state aggregation is
used to formulate an efficient solution considering the minimwn up time I down
time constraints. The performance of the algorithms are evaluated for different
systems and compared with other stochastic methods like Genetic Algorithm.Second stage of the work is concerned with solving Economic Dispatch
problem. A simple and straight forward decision making strategy is first
proposed in the Learning Automata algorithm. Then to solve the scheduling
task of systems with large number of generating units, the problem is
formulated as a multi stage decision making task. The solution obtained is
extended in order to incorporate the transmission losses in the system. To make
the Reinforcement Learning solution more efficient and to handle continuous
state space, a fimction approximation strategy is proposed. The performance of
the developed algorithms are tested for several standard test cases. Proposed
method is compared with other recent methods like Partition Approach
Algorithm, Simulated Annealing etc.As the final step of implementing the active power control loops in
power system, Automatic Generation Control is also taken into consideration.Reinforcement Learning has already been applied to solve Automatic
Generation Control loop. The RL solution is extended to take up the approach
of common frequency for all the interconnected areas, more similar to practical
systems. Performance of the RL controller is also compared with that of the
conventional integral controller.In order to prove the suitability of the proposed methods to practical
systems, second plant ofNeyveli Thennal Power Station (NTPS IT) is taken for
case study. The perfonnance of the Reinforcement Learning solution is found to
be better than the other existing methods, which provide the promising step
towards RL based control schemes for practical power industry.Reinforcement Learning is applied to solve the scheduling problems in
the power industry and found to give satisfactory perfonnance. Proposed
solution provides a scope for getting more profit as the economic schedule is
obtained instantaneously. Since Reinforcement Learning method can take the
stochastic cost data obtained time to time from a plant, it gives an
implementable method. As a further step, with suitable methods to interface
with on line data, economic scheduling can be achieved instantaneously in a
generation control center. Also power scheduling of systems with different
sources such as hydro, thermal etc. can be looked into and Reinforcement
Learning solutions can be achieved.

Abstract:
Reliability analysis is a well established branch of statistics that deals with the statistical study of different aspects of lifetimes of a system of components. As we pointed out earlier that major part of the theory and applications in connection with reliability analysis were discussed based on the measures in terms of distribution function. In the beginning chapters of the thesis, we have described some attractive features of quantile functions and the relevance of its use in reliability analysis. Motivated by the works of Parzen (1979), Freimer et al. (1988) and Gilchrist (2000), who indicated the scope of quantile functions in reliability analysis and as a follow up of the systematic study in this connection by Nair and Sankaran (2009), in the present work we tried to extend their ideas to develop necessary theoretical framework for lifetime data analysis. In Chapter 1, we have given the relevance and scope of the study and a brief outline of the work we have carried out. Chapter 2 of this thesis is devoted to the presentation of various concepts and their brief reviews, which were useful for the discussions in the subsequent chapters .In the introduction of Chapter 4, we have pointed out the role of ageing concepts in reliability analysis and in identifying life distributions .In Chapter 6, we have studied the first two L-moments of residual life and their relevance in various applications of reliability analysis. We have shown that the first L-moment of residual function is equivalent to the vitality function, which have been widely discussed in the literature .In Chapter 7, we have defined percentile residual life in reversed time (RPRL) and derived its relationship with reversed hazard rate (RHR). We have discussed the characterization problem of RPRL and demonstrated with an example that the RPRL for given does not determine the distribution uniquely

Abstract:
Software systems are progressively being deployed in many facets
of human life. The implication of the failure of such systems, has an
assorted impact on its customers. The fundamental aspect that supports a
software system, is focus on quality. Reliability describes the ability of
the system to function under specified environment for a specified
period of time and is used to objectively measure the quality. Evaluation
of reliability of a computing system involves computation of hardware
and software reliability. Most of the earlier works were given focus on
software reliability with no consideration for hardware parts or vice
versa. However, a complete estimation of reliability of a computing
system requires these two elements to be considered together, and thus
demands a combined approach. The present work focuses on this and
presents a model for evaluating the reliability of a computing system.
The method involves identifying the failure data for hardware
components, software components and building a model based on it, to
predict the reliability. To develop such a model, focus is given to the
systems based on Open Source Software, since there is an increasing
trend towards its use and only a few studies were reported on the
modeling and measurement of the reliability of such products. The
present work includes a thorough study on the role of Free and Open
Source Software, evaluation of reliability growth models, and is trying
to present an integrated model for the prediction of reliability of a
computational system. The developed model has been compared with
existing models and its usefulness of is being discussed.

Abstract:
This thesis Entitled Resource abundance and survival of indigenous ornamental fishes of central kerala with emphasis on handling and packing stress in puntius filamentosus (valenciennes).Kerala state is endowed with 41 west flowing and three east flowing rivers originating in the Western Ghats. These rivers and their vast network of tributaries and distributaries harbour rich and diversified fish fauna. Most of the freshwater fishes available in Kerala are highly appreciated as ornamental fishes in the national and international markets.Today the ornamental fish industry is one of the largest industries all over the world. The demand for ornamental fishes has been increasing steadily with the enlargement of the industry, such that the current demand for indigenous ornamental fishes have exceeded the supply. This has led to serious concern about the resources available in the country that can be utilised judiciously for the economic benefit of the state. With an aim to fill up the lacuna, a database of freshwater ornamental fishes of Kerala was created as part of the present study. Ornamental fishes destined for export marketing should thrive well in the aquarium conditions.The study reiterates fishes caught from different environmental conditions and feeding habits have a greater ability to adapt
and acclimatise to an entirely new environment and food habits.
Marketing studies based on the statistics available with Marine Products Export Development Authority show that these species are not being exported at the required level over the past 6 years,
when compared to the availability in the water bodies of Kerala. Sustainable utilisation of these resources from the wild using modern management principles and code of conduct for responsible fishing are advisable until captive breeding technology is popularised.

Abstract:
There are around 150 engineering colleges (ECs) in Kerala
under the government, aided and self financing (S.F.) sectors. While
the college libraries in the government and aided sectors receive
several grants, the libraries of S.F. colleges are solely run by their
own funds. The rising costs of scholarly publications and strict
AICTE stipulations regarding libraries and their collection, pose
great difficulties to the libraries in all sectors in finding adequate
budgets to provide quality services. Library cooperation/resource
sharing helps to overcome this problem to a considerable extent.
The present study analysed the facilities and services of the
ECs affiliated to M.G.University, Kerala to identify whether there is
a need for resource sharing (RS) among these libraries. The
satisfaction of the users with their library resources and services
were also ascertained. The study put forward a model for RS and the
opinion of the librarians and users regarding the same were
collected. Structured questionnaires were used to collect the required
data.
The study revealed that a wide gap exist between the libraries
with respect to their facilities and services and many of the S.F.
libraries have better infrastructure when compared to the
government and aided college libraries. Majority of the respondents
opined that RS is necessary to satisfy their information needs. The
model of RS proposed by the study was widely accepted by the
librarians and users. Based on the opinions and suggestions of the
respondents, the study developed the potential model for resource
sharing- the Virtual Resource Sharing Centre (VRSC).

Abstract:
Queueing system in which arriving customers who find all servers and waiting positions (if any) occupied many retry for service after a period of time are retrial queues or queues with repeated attempts. This study deals with two objectives one is to introduce orbital search in retrial queueing models which allows to minimize the idle time of the server. If the holding costs and cost of using the search of customers will be introduced, the results we obtained can be used for the optimal tuning of the parameters of the search mechanism. The second one is to provide insight of the link between the corresponding retrial queue and the classical queue. At the end we observe that when the search probability Pj = 1 for all j, the model reduces to the classical queue and when Pj = 0 for all j, the model becomes the retrial queue. It discusses the performance evaluation of single-server retrial queue. It was determined by using Poisson process. Then it discuss the structure of the busy period and its analysis interms of Laplace transforms and also provides a direct method of evaluation for the first and second moments of the busy period. Then it discusses the M/ PH/1 retrial queue with disaster to the unit in service and orbital search, and a multi-server retrial queueing model (MAP/M/c) with search of customers from the orbit. MAP is convenient tool to model both renewal and non-renewal arrivals. Finally the present model deals with back and forth movement between classical queue and retrial queue. In this model when orbit size increases, retrial rate also correspondingly increases thereby reducing the idle time of the server between services

Abstract:
Imprisonment is the most common method of punishment resorted to by almost all legal systems.The new theories of crime causation propounded in the latter half of the nineteenth century gave rise to the
feeling that the prisons could be used as appropriate institutions for reforming the offenders. It called for individualisation of punishment.As a result of international movements for humanisation of prisons the judiciary' in tine common law countries started taking active interest in prisoner's treatment.Various studies reveal that much has been done in America to improve the lot of prisoners and to treat them as
human beings.The courts there have gone to the extent of saying that there is no iron curtain between a prisoner and the constitution. Most of the rights available to citizens except those which they cannot enjoy due to the conditions of incarceration have also been granted to prisoner.In India also the judiciary has come forward to protect the rights of the prisoners.Maneka Gandhi is a turning point in prisoner's rights.The repeated intervention of courts in prison administration project the view that prisoners have been denied the basic human rights.The High Courts and the Supreme Court of India have been gradually exercising jurisdiction ixl assuming prison justice, including improving the quality of food and amenities, payment of wages and appropriate standards of medical care. Access to courts must be made easier to the aggrieved prisoners.The government should come forward along with some public spirited citizens and voluntary organisations to form a "discharged prisoner“ aid society. The society should exploit opportunities for rehabilitation of prisoners after their release.Most of the prison buildings in the State of Kerala are ill-equipped, ill furnished and without proper ventilation or sanitation and with insufficient water supply arrangements.In India prisoners and prisons today are governed by the old central legislations like Prisons Act l894 Prisoners Act 1900 and the Transfer of Prisoners Act 1950.

Domestic violence is a gender based violation of human rights having
multi- dimensional repercussions in the well- being of individuals in family
and society. The Indian legislation to protect the women from domestic
violence is significant in providing a mechanism for enforcing positive civil
rights of protection and injunction orders to the victims of domestic violence
along with the existing remedies of criminal sanctions. However the Act was
brought in the backdrop of an established tradition of cohesive and stable
family setting. This, in turn, results in the emergence of new issues and
challenges which necessitates deeper understandings of indigenous sociocultural
institutions in India i.e., marriage and family. This study is an attempt
to analyse the Indian law on domestic violence and to assess whether the law
addresses and answers the problems of domestic violence effectively in the

Abstract:
This thesis entitled “The right to freedom of information in india”.In a democracy, the citizens being the persons to choose their own governors, the right to know from the Government is a pre-condition for a properly evaluated election. Freedom of speech and expression, one of the repositories of self~government, forms the basis for the right to know in a wider scale. The functions which the free speech rights serve in a society also emphasize the need for more openness in the functioning of a democracy.Maintanance of law and order and investigation of crimes are highly important in a country like India, where no risk may be taken on account of the public‘s right to know.
The Indian situations relating terrorist activities, riots based on language, region, religion and caste are important in this respect. The right to know of the citizens may be regulated in the interests of secrecy required in these areas.On the basis of the conclusions reached in this study, a draft Bill has been proposed for the passing of an Access to Public Documents Act. This Bill is appended to this Thesis.

The nature and extent of protection secured to
personal liberty has been a subject matter of great
controversy and debate. The expression "procedure
established by law" as a standard of protection for personal
liberty has been looked upon as highly unsatisfactory and

that are separately guaranteed under Art.19, ‘personal
liberty‘ as guaranteed by Art.21 does not obligate the
.Legislature to comply with the requirements of justice and
reasonableness as and when it enchroaches upon that right.
Though the concept of ‘personal liberty‘ has received an
evolutive and expansive meaning through judicial process,
the standard of protection which the judicial process could
secure to personal liberty through the interpretation of
Art.21 has been far from satisfactory Even after four
decades of judicial process in the interpretation of Art.21 the problem of evolving a just and adequate standard of
protection for personal liberty in that Article continues to
be 21 crucial constitutional issue, craving for a.
satisfactory solution. And the present study is a humble
attempt to unravel this problem and to Search for a
reasonable solution.

India is a signatory to the United Nations Declaration of Human
Rights 1948 and the International Covenant on Civil and Political 1966,
the two major International instruments, building the foundations of the
major democracies and the constitutions of the world. Both these
instruments give an independent and upper position to right to privacy
compared to right to freedom of speech and expression. The freedom of
press finds its place under this right to freedom of speech and expression.
Both these rights are the two opposite faces of the same coin. Therefore,
without the right of privacy finding an equal place in Indian law
compared to right to freedom of speech and expression, the working of
democracy would be severely handicapped and violations against
citizens rights will be on the rise It was this problem in law and need to bring a balance between
these two conflicting rights that induced me to undertake this venture.
This heavy burden to bring in a mechanism to balance these two rights
culminated in me to undertake this thesis titled “Right to Privacy and

Abstract:
The main objective of the study is primarily to determine the magnitude of selected trace elements, the concentrations of which would possibly accelerate growth resulting in larger biomass and sustained period of exponential phase for economically viable harvest. The study on the effect of three trace elements namely Cu, Mn and Zn on two species of algae,ISOChrySiS galbana Parke and Synechocystib salina Wislouch under different conditions of salinity, PH and temperature involves several combinations for each metal, from which the relative set of conditions has been adduced. The scheme of the experiments was statistically designed for interpretation of data and factors were assessed and graded according to relative importance. The methodology adopted for data interpretation is analysis of variance by split-plot design method.
The thesis has been divided into five chapters. The introductory chapter explains the relevance of the research work undertaken. Chapter 11 gives a review on the work pertaining to the above mentioned three trace elements in relation to nutrition as well as on the toxic aspects about which there is an abundance of literature. Chapter Ill presents a detailed description of the material and specialised methods followed for the study. The results and conclusions of the various experiments on effect of metals on growth and other physiological activities are discussed in Chapters IV and V.
