Abstract:
In India, film censorship originated with Cinematograph Act 1918 empowering
the Provincial Governments to establish censorial authorities. In 1949, an
amendment provided for a Central Board of Film Censors. In 1952, a new
legislation gave the Central Government enormous powers, making the Board
to function as a department of the Central Government. The Government had
control over the Board with the mechanism of issuing 'directions' to the censors
and laying down censorship rules. The legislation did not provide any objective
criteria for censoring films. The 1959 amendment, aimed at curing this defect,
only incorporated the grounds contained in Article 19(2) of the Constitution. Even
after expert studies and a significant decision by the Supreme Court, pointing
out the inadequacy of the existing system, and governmental attempts to bring
reforms by way of fresh directions, appointment of appellate authority and framing
of new rules, the system still warrants radical change. The thesis explores them.

Abstract:
Design and development of a circularly polarized and matched H-plane sectorial horn antenna have been reported By
proper trimming of the flange parameters any desired polarization can be obtained from the horn
Design of a dual-port circular patch antenna with a sector-slot for dual-frequency operation is presented. The antenna resonates at two distinct frequencies with orthogonal polarizations and broad radiation characteristics. Unlike the conventional circular patch, this antenna can be microstrip-fed to operate at either of the resonances. The two polarizations can be simultaneously excited using two electromagnetically coupled ports with an isolation better than −30 dB between the ports. This antenna has the added advantage of size reduction of 44% compared to the conventional circular patch without any reduction in gain.

Abstract:
The present thesis is an attempt by the researcher to Investigate the surface circulation of the Indian Ocean, north of 2095 in relation to the atmospheric circulation over the ocean. The aim is achieved by working out the circu1ation pattern and correlating it with the computed
wind stress and its vorticity. The month wise surface circulation is arrived by drawing the streamlines, using freshand method with superimposed isotache. The zonal ad meridional componance of the wind stress and the curl of the wind stress are computed for each month over 2° latitude longitude quadrangle from the bulk aerodynamic formula, using a computer program. The data for drawing the surface circu1ation and for computing the wind stress and its curl have come from the Dutch Atlas.

Abstract:
Image processing has been a challenging and multidisciplinary research area since decades with continuing improvements in its various branches especially Medical Imaging. The healthcare industry was very much benefited with the advances in Image Processing techniques for the efficient management of large volumes of clinical data. The popularity and growth of Image Processing field attracts researchers from many disciplines including Computer Science and Medical Science due to its applicability to the real world. In the meantime, Computer Science is becoming an important driving force for the further development of Medical Sciences.
The objective of this study is to make use of the basic concepts in Medical Image Processing and develop methods and tools for clinicians’ assistance. This work is motivated from clinical applications of digital mammograms and placental sonograms, and uses real medical images for proposing a method intended to assist radiologists in the diagnostic process. The study consists of two domains of Pattern recognition, Classification and Content Based Retrieval. Mammogram images of breast cancer patients and placental images are used for this study.
Cancer is a disaster to human race. The accuracy in characterizing images using simplified user friendly Computer Aided Diagnosis techniques helps radiologists in detecting cancers at an early stage. Breast cancer which accounts for the major cause of cancer death in women can be fully cured if detected at an early stage. Studies relating to placental characteristics and abnormalities are important in foetal monitoring. The diagnostic variability in sonographic examination of placenta can be overlooked by detailed placental texture analysis by focusing on placental grading. The work aims on early breast cancer detection and placental maturity analysis. This dissertation is a stepping stone in combing various application domains of healthcare and technology.

Abstract:
A new procedure for the classification of lower case
English language characters is presented in this work . The
character image is binarised and the binary image is
further grouped into sixteen smaller areas ,called Cells .
Each cell is assigned a name depending upon the contour present in the cell and occupancy of the image contour in the cell. A data reduction procedure called Filtering is adopted to eliminate undesirable redundant information for
reducing complexity during further processing steps .
The filtered data is fed into a primitive extractor where
extraction of primitives is done .
Syntactic methods are employed for the classification of
the character . A decision tree is used for the interaction of the various components in the scheme . 1ike the
primitive extraction and character recognition. A character is recognized by the primitive by primitive construction
of its description . Openended inventories are used
for including variants of the characters and also adding
new members to the general class . Computer implementation
of the proposal is discussed at the end using handwritten
character samples . Results are analyzed and suggestions
for future studies are made. The advantages of the proposal
are discussed in detail .

Abstract:
Cancer treatment is most effective when it is detected early and the progress in
treatment will be closely related to the ability to reduce the proportion of misses in the
cancer detection task. The effectiveness of algorithms for detecting cancers can be
greatly increased if these algorithms work synergistically with those for characterizing
normal mammograms. This research work combines computerized image analysis
techniques and neural networks to separate out some fraction of the normal
mammograms with extremely high reliability, based on normal tissue identification and
removal.
The presence of clustered microcalcifications is one of the most important and
sometimes the only sign of cancer on a mammogram. 60% to 70% of non-palpable
breast carcinoma demonstrates microcalcifications on mammograms [44], [45], [46].WT based techniques are applied on the remaining mammograms, those are obviously
abnormal, to detect possible microcalcifications. The goal of this work is to improve the
detection performance and throughput of screening-mammography, thus providing a
‘second opinion ‘ to the radiologists.
The state-of- the- art DWT computation algorithms are not suitable for practical
applications with memory and delay constraints, as it is not a block transfonn. Hence in
this work, the development of a Block DWT (BDWT) computational structure having
low processing memory requirement has also been taken up.

Abstract:
Suffix separation plays a vital role in improving the quality of
training in the Statistical Machine Translation from English into Malayalam.
The morphological richness and the agglutinative nature of Malayalam make it
necessary to retrieve the root word from its inflected form in the training
process. The suffix separation process accomplishes this task by scrutinizing the
Malayalam words and by applying sandhi rules. In this paper, various
handcrafted rules designed for the suffix separation process in the English
Malayalam SMT are presented. A classification of these rules is done based on
the Malayalam syllable preceding the suffix in the inflected form of the word
(check_letter). The suffixes beginning with the vowel sounds like ആല, ഉെെ, ഇല
etc are mainly considered in this process. By examining the check_letter in a
word, the suffix separation rules can be directly applied to extract the root
words. The quick look up table provided in this paper can be used as a guideline
in implementing suffix separation in Malayalam language
A graphs G is clique irreducible if every clique in G of size at least two,has an edge which does not lie in any other clique of G and is clique reducible if it is not clique irreducible. A graph G is clique vertex irreducible if every clique in G has a vertex which does not lie in any other clique of G and clique vertex reducible if it is not clique vertex irreducible. The clique vertex irreducibility and clique irreducibility of graphs which are non-complete extended p-sums (NEPS) of two graphs are studied. We prove that if G(c) has at least two non-trivial components then G is clique vertex reducible and if it has at least three non-trivial components then G is clique reducible. The cographs and the distance hereditary graphs which are clique vertex irreducible and clique irreducible are also recursively characterized.

Abstract:
In this paper, two notions, the clique irreducibility and clique vertex
irreducibility are discussed. A graph G is clique irreducible if every
clique in G of size at least two, has an edge which does not lie in any
other clique of G and it is clique vertex irreducible if every clique in G
has a vertex which does not lie in any other clique of G. It is proved
that L(G) is clique irreducible if and only if every triangle in G has a
vertex of degree two. The conditions for the iterations of line graph,
the Gallai graphs, the anti-Gallai graphs and its iterations to be clique
irreducible and clique vertex irreducible are also obtained.

Abstract:
The tiniest Union territory of India, Lakshadweep, is an archipelago, with an area
of 32 Sq. km. consisting of 12 atolls, three reefs and five submerged banks, lies
between 8° and 12°30'N latitudes and 71° and 74" E longitudes. It is one of the
most important and critical territories of India from economic and defence point
of view. Specialised environment having typical geological set up, Lakshadweep is
ecologically sensitive to even slight climatic or anthropogenic interference.
Pollution of coastal seas, over exploitation and contamination of the fresh water
sources are thus become great concerns to the existence of the island. Typical
geological set up and interference cause threat to the ecology of the fragile
environment and resources of the island as well as its resources. Marine pollution
and ground water contamination are concerns in this regard. Even though attentions were made to assess the physico—chemical and bacteriological status of the marine and groundwater systems separately, an integrated approach has not been evolved. The present study with its broad objectives is attempted for an integrated assessment of microbiological, physicochemical and biological characteristics of the surrounding seawater and microbiological and physico—chemical characteristics of the ground water in Kavaratti island. The entire study has been organised in 4 chapters

Abstract:
Coastal Regulation Zone (CRZ) notification was issued by the Ministry of Environment
and Forest of Government of India in February 1991 as a part of the Environmental
Protection Act of 1986 to protect the coast from eroding and to preserve its natural resources.
The initial notification did not distinguish the variability and diversity of various coastal states
before enforcing it on the various states and Union Territories. Impact assessments were not
carried out to assess its impact on socio-economic life of the coastal population. For the very
same reason, it was unnoticed or rather ignored till 1994 when the Supreme Court of India
made a land mark judgment on the fate of the coastal aquaculture which by then had
established as an economically successful industry in many South Indian States. Coastal
aquaculture in its modern form was a prohibited activity within CRZ. Lately, only various
stakeholders of the coast realized the real impact of the CRZ rules on their property rights andbusiness. To overcome the initial drawbacks several amendments were made in the regulation
to suit regional needs.
In 1995, another great transformation took place in the State of Kerala as a part of the reorganization
of the local self government institutions into a decentralized three tier
system called ‘‘Panchayathi Raj System’’. In 1997, the state government also decided to
transfer the power with the required budget outlay to the grass root level panchayats
(villages) and municipalities to plan and implement the various projects in their localities
with the full participation of the local people by constituting Grama Sabhas (Peoples’ Forum).
It is called the ‘‘Peoples’ Planning Campaign’’(Peoples’ Participatory Programme—PPP
for Local Level Self-Governance). The management of all the resources including the local
natural resources was largely decentralized to the level of local communities and villages.
Integrated, sustainable coastal zone management has become the concern of the local
population.
The paper assesses the socio-economic impact of the centrally enforced CRZ and the state
sponsored PPP on the coastal community in Kerala and suggests measures to improve the
system and living standards of the coastal people within the framework of CRZ.
