Abstract:
As of 1999. the state of Kerala has 3210 offices of scheduled
commercial banks (SCBS). In all, there are 48 commercial banks
operating in Kerala, which includes PSBs, OPBs, NPBS. FBs, and
Gramin Banks. The urban areas give a complete picture of the
competition in the present day banking scenario with the presence
of all bank groups. Semi-urban areas of Kerala have 2196 and urban
areas have 593 as on March 1995.“ The study focuses on the
selected segments ofthe urban customers in Kerala which is capable
of giving the finer aspects of variation in customer behaviour in the
purchase of banking products and services. Considering the
exhaustive nature of such an exercise, all the districts in the state
have not been brought under the purview of the study. Instead. three
districts with largest volume of business in terms of deposits,
advances, and number of offices have been short listed as
representative regions for a focused study.
The study focuses on the retail customer segment and their
perceptions on the various products or services offered to them. Non
Resident Indians (NRIs), and Traders and Small—ScaIe Industries
segments have also been included in the study with a view to obtain
a comparative picture with respect to perception on customer
satisfaction and service quality dimensions and bank choice
behaviour. The research is hence confined to customer behaviour
and the implications for possible strategies for segmentation within
the retail segment customers

Abstract:
In the current study, epidemiology study is done by means of
literature survey in groups identified to be at higher potential for DDIs as
well as in other cases to explore patterns of DDIs and the factors affecting
them. The structure of the FDA Adverse Event Reporting System (FAERS)
database is studied and analyzed in detail to identify issues and challenges
in data mining the drug-drug interactions. The necessary pre-processing
algorithms are developed based on the analysis and the Apriori algorithm is
modified to suit the process. Finally, the modules are integrated into a tool to identify DDIs. The results are compared using standard drug interaction
database for validation. 31% of the associations obtained were identified to
be new and the match with existing interactions was 69%. This match
clearly indicates the validity of the methodology and its applicability to
similar databases. Formulation of the results using the generic names
expanded the relevance of the results to a global scale. The global
applicability helps the health care professionals worldwide to observe
caution during various stages of drug administration thus considerably
enhancing pharmacovigilance

Abstract:
The present research problem is to study the existing encryption
methods and to develop a new technique which is performance wise
superior to other existing techniques and at the same time can be very
well incorporated in the communication channels of Fault Tolerant
Hard Real time systems along with existing Error Checking / Error
Correcting codes, so that the intention of eaves dropping can be
defeated. There are many encryption methods available now. Each
method has got it's own merits and demerits. Similarly, many crypt
analysis techniques which adversaries use are also available.

Abstract:
An attempt has been made in this thesis to model some of the emissions observed
by SPICAM and SPICAV on Mars and Venus, respectively, viz., CO Cameron band,
CO+
2 ultraviolet doublet, N2 triplet bands, atomic oxygen green (5577 A), red doublet
(6300, 6364 A), and ultraviolet (2972 A) emissions. One of major sources of these
emissions is photoelectron impact ionization/excitation. In this thesis, an electron
degradation model based on Monte Carlo technique has been developed to calculate
the production/excitation rates of above mentioned emissions due to electron impact.
The limb brightness pro les of emissions are calculated and compared with the observations
wherever available. The e ect of various model input parameters on dayglow
emissions intensities is also evaluated

Abstract:
The present study is the first attempt to understand population characteristics of the deep-sea pandalid shrimp, P. quasigrandis and to assess the status of these resources off Kerala coast.Total mortality coefficient (Z) of P. quasigrandis estimated by various methods.Natural mortality coefficient (M) calculated was 0.65 and 1.02 by Pauly‟sempirical formula and Srinaths‟s formula respectively
The deep-sea shrimp P. quasigrandis exploited from the present fishing ground and their monetary return has started showing a declining trend. By observing the current yield and economic return, there is no further scope for increasing the catch from the present fishing ground. The study indicated that majority of the deep-sea shrimp trawlers, especially targeted for pandalid shrimps still concentrated off Kollam area (Quilon Bank). Even though researchers had located several potential deep-sea fishing grounds based on exploratory surveys in Indian EEZ , fishermen are unaware of these fishing grounds located and hence sharing the information about new potential deep-sea fishing grounds could avert the possible stock decline due to the intensive targeted deep-sea shrimp fishery in the Quilon Bank. Hence, the present
study recommended that part of the effort from existing fishing grounds may be shifted to newly located deep-sea fishing grounds which will help in a sustainableexploitation of deep-sea resources off Kerala coast.

Abstract:
The present thesis can be divided into three areas:1) the
fabrication of a low temperature photo-luminescence and photoconductivity
measuring unit 2) photo-luminescence in the chalcopyrite
CulnSez and CulnS2 system for defect and composition analysis and
3) photo-luminescence and photo-conductivity of In:JS3. This thesis
shows that photo-luminescence is one of most essential semiconductor
characterization tool for a scientific group working on photovoltaics.
Tools which can be robust, non-destructive, requiring minimal sample
preparation for analysis and most informative of the device
applications are sought after by industries and this thesis is towards
establishing photo-luminescence as "THE" tool for semiconductor
characterization. The possible application of photo-luminescence as a
tool for compositional and quality analysis of semiconductor thin
films has been worked upon by this thesis. Photo-conductivity
complement photo-luminescence and together they provide all the
information required for the fabrication of an opto-electronic device.

Abstract:
Over the past decade, there is a great demand for permission to transmit large bandwidth
concurrent with existing narrowband signals. In 2002, the federal communications
commission (FCC) decided to permit use of ultrawideband (UWB) systems.
UWB systems are unique in their large instantaneous bandwidth and potential for lowcost
digital design that enables a single system to operate in different modes as a
communication device, radar etc. UWB systems aim at covering the frequency band of
3.1-10.6 GHz defined by the FCC. The addition of more and more features in each new
generation communication system demands universal antennas suitable for operation in
multiple bands. In this regard, designing a multiband antenna which also covers the
UWB range without deteriorating the UWB performance is of great interest. Also, a
significant issue in communication systems is to miniaturize the antenna size while
providing good performance over the operation bands.
The thesis presents three different designs of CPW-fed multiband antennas. The first
design uses a fractal concept to achieve multiband operation. In the second and third
designs, a slotted circular monopole and a spiral monopole are used respectively for
multiband operation with UWB applications. For both these cases, variations from the
basic antenna geometry are also proposed in which the frequency of operation is
lowered without increase in overall antenna size. Design guidelines are developed for
all antennas to facilitate design on substrates of different permittivity and thickness. The
antennas are analyzed in both frequency and time domain for complete characterization

Abstract:
This work is aimed at building an adaptable frame-based system for processing Dravidian languages. There are about 17 languages in this family and they are spoken by the people of South India.Karaka relations are one of the most important features of Indian languages. They are the semabtuco-syntactic relations between verbs and other related constituents in a sentence. The karaka relations and surface case endings are analyzed for meaning extraction. This approach is comparable with the borad class of case based grammars.The efficiency of this approach is put into test in two applications. One is machine translation and the other is a natural language interface (NLI) for information retrieval from databases. The system mainly consists of a morphological analyzer, local word grouper, a parser for the source language and a sentence generator for the target language. This work make contributios like, it gives an elegant account of the relation between vibhakthi and karaka roles in Dravidian languages. This mapping is elegant and compact. The same basic thing also explains simple and complex sentence in these languages. This suggests that the solution is not just ad hoc but has a deeper underlying unity. This methodology could be extended to other free word order languages. Since the frame designed for meaning representation is general, they are adaptable to other languages coming in this group and to other applications.

Abstract:
This is a Named Entity Based Question Answering System for Malayalam
Language. Although a vast amount of information is available today in digital
form, no effective information access mechanism exists to provide humans with
convenient information access. Information Retrieval and Question Answering
systems are the two mechanisms available now for information access.
Information systems typically return a long list of documents in response to a
user’s query which are to be skimmed by the user to determine whether they
contain an answer. But a Question Answering System allows the user to state
his/her information need as a natural language question and receives most
appropriate answer in a word or a sentence or a paragraph.
This system is based on Named Entity Tagging and Question Classification.
Document tagging extracts useful information from the documents which will be used
in finding the answer to the question. Question Classification extracts useful
information from the question to determine the type of the question and the way in
which the question is to be answered. Various Machine Learning methods are used to
tag the documents. Rule-Based Approach is used for Question Classification.
Malayalam belongs to the Dravidian family of languages and is one of the
four major languages of this family. It is one of the 22 Scheduled Languages of
India with official language status in the state of Kerala. It is spoken by 40 million
people. Malayalam is a morphologically rich agglutinative language and relatively
of free word order. Also Malayalam has a productive morphology that allows the
creation of complex words which are often highly ambiguous.
Document tagging tools such as Parts-of-Speech Tagger, Phrase Chunker,
Named Entity Tagger, and Compound Word Splitter are developed as a part of
this research work. No such tools were available for Malayalam language. Finite
State Transducer, High Order Conditional Random Field, Artificial Immunity System Principles, and Support Vector Machines are the techniques used for the
design of these document preprocessing tools.
This research work describes how the Named Entity is used to represent
the documents. Single sentence questions are used to test the system. Overall
Precision and Recall obtained are 88.5% and 85.9% respectively. This work can be
extended in several directions. The coverage of non-factoid questions can be
increased and also it can be extended to include open domain applications.
Reference Resolution and Word Sense Disambiguation techniques are suggested as
the future enhancements
