Abstract:
Embedded systems are usually designed for a single or a specified set of
tasks. This specificity means the system design as well as its hardware/software
development can be highly optimized. Embedded software must meet the
requirements such as high reliability operation on resource-constrained
platforms, real time constraints and rapid development. This necessitates the
adoption of static machine codes analysis tools running on a host machine for
the validation and optimization of embedded system codes, which can help
meet all of these goals. This could significantly augment the software quality
and is still a challenging field.Embedded systems are usually designed for a single or a specified set of

error localization and optimization technique assisting the embedded system
designer in software debugging, to make it more effective at early detection of
software bugs that are otherwise hard to detect, using the static analysis of
machine codes. The focus of this work is to develop methods that automatically
localize faults as well as optimize the code and thus improve the debugging
process as well as quality of the code.Validation is done with the help of rules of inferences formulated for the
target processor. The rules govern the occurrence of illegitimate/out of place
instructions and code sequences for executing the computational and integrated peripheral functions. The stipulated rules are encoded in propositional logic
formulae and their compliance is tested individually in all possible execution
paths of the application programs. An incorrect sequence of machine code
pattern is identified using slicing techniques on the control flow graph
generated from the machine code.An algorithm to assist the compiler to eliminate the redundant bank
switching codes and decide on optimum data allocation to banked memory
resulting in minimum number of bank switching codes in embedded system
software is proposed. A relation matrix and a state transition diagram formed
for the active memory bank state transition corresponding to each bank
selection instruction is used for the detection of redundant codes. Instances of
code redundancy based on the stipulated rules for the target processor are
identified.This validation and optimization tool can be integrated to the system
development environment. It is a novel approach independent of
compiler/assembler, applicable to a wide range of processors once appropriate
rules are formulated. Program states are identified mainly with machine code
pattern, which drastically reduces the state space creation contributing to an
improved state-of-the-art model checking. Though the technique described is
general, the implementation is architecture oriented, and hence the feasibility
study is conducted on PIC16F87X microcontrollers. The proposed tool will be
very useful in steering novices towards correct use of difficult microcontroller
features in developing embedded systems.

Abstract:
In the present study, an attempt has been made to prepare composites
by incorporating expanded graphite fillers in insulating elastomer matrices
and to study its DC electrical conductivity, dielectric properties and
electromagnetic shielding characteristics, in addition to evaluating the
mechanical properties. Recently, electronic devices and components have
been rapidly developing and advancing. Thus, with increased usage of
electronic devices, electromagnetic waves generated by electronic systems
can potentially create serious problems such as malfunctions of medical
apparatus and industry robots and can even cause harm to the human body.
Therefore, in this work the applicable utility of the prepared composites as
electromagnetic interference (EMI) shielding material are also investigated.
The dissertation includes nine chapters

Abstract:
The microalgae gained importance as food and feed as well as source of fine
chemicals since the l960’s. Spirulina became the trend setter due to its easily
culturable properties as well as nutritional composition. A rapid expansion of
microalgal industry occurred in the Asia-Pacific region as microalgae came to
stay as a health food supplement.
Microalgae have been an integral component of oxidation ponds usually
incorporated with wastewater treatment. Over the last few decades, efforts
have been made to apply intensive microalgal cultures to perform biological
tertiary treatment of secondary effluents. Given the limited number of species
still available for commercial exploitation, it is imperative to isolate and
cultivate those photosynthetic organisms with high growth rate and biomass
accumulation, which could play the dual role of cleaning the wastewater and
also providing useful biomass. This has been the objective of this study ie.
0 To develop pure cultures of local isolates of Cyanobacteria for
extraction of biochemicals of commercial value
0 To couple biomass production with effluent treatment

Abstract:
Aquaculture is one of the prime catalysts for the socio-economic development of Indian economy contributing to the nations food and nutritional security, export earnings, income and employment generation. In this study an evaluation of extension activities in the development of aquaculture in Kerala. This study was conducted with a view to examine how the Kerala fisheries department offered extension services to the aquaculture farmers in the freshwater and brackish water sectors of the state through various agencies like Fish Farmers Development Agency(FFDA), Brackish water Fish Farmers Development Agency (BFFDA). In this study there are 3 category of respondent’s fresh water beneficiary farmers, brackish water beneficiary farmers and fisheries extension officers. The main motive of the thesis is to make an attempt to explore the responses of local producers to the extension programs of the state with special reference to the aquaculture sector of Kerala, India.
The most important technical constraint faced by the fresh water farmers was lack of knowledge followed by non-availability of quality seeds. In the case of brackish water farming, it was infection of disease followed by lack of knowledge. The overall activities of the department of fisheries were ‘fairly good’. It indicate the need for improvements in the delivery of extension services to various target groups. The state fisheries department has already moving towards evolving these modes of extension activities by community participation.

Abstract:
In the present study the preparation and characterisation of rubber ferrite
composites (RFC) containing barium ferrite (BaF) and strontium ferrite (SrF) have
been dealt with. The incorporation of the hard ferrites into natural and nitrile rubber
was carried out according to a specific recipe for various loadings of magnetic
fillers. For this, the ferrite materials namely barium ferrite and strontium ferrite
having the general formula MO6Fe2O3 have been prepared by the conventional
ceramic techniques. After characterisation they were incorporated into the natural
and nitrile rubber matrix by mechanical method. Carbon black was also incorporated at different loading into the rubber ferrite composites to study its
effect on various properties. The cure characteristics, mechanical, dielectric and
magnetic properties of these composites were evaluated. The ac electrical
conductivity of both the ceramic ferrites and rubber ferrite composites were also
calculated using a simple relation. The investigations revealed that the rubber ferrite composites with the
required dielectric and magnetic properties can be obtained by the incorporation of
ferrite fillers into the rubber matrix, without compromising much on the
processability and mechanical properties.

Abstract:
The thesis entitled An Evaluation of Primary Health Care System in Kerala. The present study is intended to examine the working of primary health care system and its impact on the health status of people. The hypothesis tested in the thesis includes,
a. The changes in the health profile require reallocation of resources of primary health care system,
b. Rate of utilization depends on the quality of services provided by primary health centers, and c. There is a significant decline in the operational efficiency of the primary health care system.
The major elements of primary health care stated in the report of AlmaAta International Conference on Primary Health Care (WHO, 1994)” is studied on the basis of the classification of the elements in to three: Preventive, Promotive, and Curative measures. Preventive measures include Maternal and Child Health Care including family Planning. Provision of water and sanitation is reviewed under promotive measures. Curative measures are studied using the
disease profile of the study area. Collection of primary data was done through a sample survey, using pre-tested interview schedule of households of the study area. Multi stage random sampling design was used for selecting the sample. The design of the present study is both descriptive and analytical in nature. As far as the analytical tools are concerned, growth index, percentages, ratios, rates, time series analysis, analysis of variance, chi square test, Z test
were used for analyzing the data. Present study revealed that no one in these areas was covered under any type of health insurance. Conclusion states that considering the present changes in the health profile, traditional pattern of resource allocation should be altered to meet the urgent health care needs of the people. Preventive and promotive measures like health education for
giving awareness among people to change health habits, diet pattern, life style etc. are to be developed. Proper diagnosis and treatment of the disease at the beginning of the stage itself may help to cure majority of disease. For that, Public health policy must ensure the primary health care as enunciated at Alma- Ata international Conference. At the same time Public health is not to be treated as the sole responsibility of the government. Active community participation is an essential means to attain the goals.

Abstract:
Transport of live aquatic organisms which is more than a century old,
perhaps started in the 1870's (Norris et al, 1960). Live fish transportation is
an essential practice in aquaculture particularly in rural areas of developing
countries representing the only means of supplying fry to small scale aqua
culturists (Taylor and Ross, 1988). Very often, large numbers of fry,
fingerlings, juveniles and adult fish are being transported from the hatchery
to fish farms, fish farms to market, processors and consumers. Live fish
command large economic importance in the fresh fish market than dead and
iced fish. Medina Pizzali (2001) observed that live fish in the Kolkata market
was usually sold at higher prices than dead fish and most consumers were
prepared to pay premium prices for live fish, which is considered as the best
guarantee of freshness, quality, and intrinsic characteristics of its flesh (better
texture and delicate flavour) in comparison with fresh/chilled seafood.
Various government and private agencies undertake transport of live fish for
commercial live fish market or for artificial propagation of game

Abstract:
Drainage basins are durable geomorphic features that provide insights into the long term evolution of the landscape. River basin geometry develop response to the nature and distribution of uplift and subsidence, the spatial arrangement of lineaments (faults and joints), the relative resistance of different rock types and to climatically influenced hydrological parameters . For developing a drainage basin evolution history, it is necessary to understand physiography, drainage patterns, geomorphic features and its structural control and erosion status. The present study records evidences for active tectonic activities which were found to be responsible for the present day geomorphic set up of the study area since the Western Ghat evolution. A model was developed to explain the evolution of Chaliar River drainage basin based on detailed interpretation of morphometry and genesis of landforms with special emphasis on tectonic geomorphic indices and markers.

Abstract:
This thesis entitled Exceptions and limitations to intellectual property rights with special reference to patent and copyright law.The study on the limitations and exceptions to copyright and patent was mainly characterized by its diversity and flexibility. The unique feature of limited monopoly appended to intellectual property was always a matter of wide controversy.The historical analysis substantiated this instrumentalist philosophy of intellectual property.the study from a legal space characterized by diversity and flexibility and end up in that legal space being characterized by homogeneity and standardization. The issue of flexibility and restrictiveness in the context of TRIPS is the next challenging task. Before devising flexibility to TST, the question to be answered is whether such a mechanism is desirable in the context of TRIPS.In conclusion it is submitted to reorient the intellectual property framework in the context of the noble public interest objectives.
