J Adv Sci Technol 2006, 9(1-2), 46-55.
The distance mode of education has gained considerable popularity in last decade. The concept of distance mode has progressed over the decades from Correspondence education model (First generation), Multimedia model (Second Generation), Tele-Iearning model (Third Generation) to Flexible Learning model (Fourth Generation) [Jim' Taylor, 1998]. The goal of distance learning is to make the learner an independent and effective professional. The time-tested technology is the print medium. The self-instruction material in the form of books should be easy to follow and be able to attack a concept at different angles to enable effective learning in the heterogeneous target group [Rowntree D., 1990]. Studies a curious mix of target groups in this communication. A subject matter (Digital Computer Electronics) is being taught in conventional mode (University of Pune, Pune) as well distance mode (Yashwantrao Chavan Maharashtra Open University, Nashik) using the same printed book ("Digital Computer Electronics" by A.P. Malvino and Brown, published by Tata Mc Graw Hill, Delhi 3'd Edition 1993). A comparative study of the learning experiences and the feedback from these dissimilar groups shed lights on some of the very interesting features of learning through the two modes.

Attitude values expressed could be used to examine whether these values have any relevance on the mode the commuter selects for his actual use. In this study it was tested by the following approaches: - Compared the overall attitude values of an individual for different modes based on his stated preferences and examined whether the mode of his normal travel was the same as the one for which his attitude value was the highest. Aggregated the sample and divided it into different segments so that each set would form a homogenous group. Two approaches made use of were MLR and MNL models. Multi-Nomial Logit (MNL) models developed in this study have clearly brought out that attitude of users towards a mode influences actual choice significantly in case of motorized vehicle owners. Amongst non-vehicle owners, attitude has very little impact on choice. Delhi, the capital metropolis of India, has been considered as a case study.

Paper is aimed at extending the scope of Webometrics by providing it with new knowledge extraction and visualization capabilities. An application of this approach on a dataset of websites issued from European universities is presented. The basic model which is considered in this paper is a multi-topographic neural network model. The powerful features of this model are its generalization mechanism and its mechanism of communication between topographies. Both mechanisms enable rule extraction, whenever a single viewpoint or multiple viewpoints on the same data are considered. The association rule extraction is itself based on original quality measures which evaluate to what extent a numerical classification model behaves as a natural symbolic classifier such as a Galois lattice. The visualization of the results of the analyses is based on an original hyperbolic approach.

National Aerospace Laboratories (NAL), Bangalore, India's premier civil R&D establishment in aeronautics and allied disciplines, has embarked on a major civil aircraft development programme to build a multi-role light transport aircraft named SARAS. Initiatives were taken by the Information Management Division of NAL in setting up a state-of the-art multimedia laboratory combined with the judicial selection of appropriate digital camera infrastructure. This paved the way for a systematic approach to digitally capture, archive and retrieve "SARAS digital information". As an ambitious initiative carried out in digital content management, the SARAS aircraft programme has so far generated nearly 6621 minutes of digitally recorded video during the period 2002 - 2006 archived on to 172 digital magnetic tapes. And most importantly, close to 0.255 terabytes of SARAS digital video have been archived onto DVDs spread over 55 DVDs. Digital video will remain an expensive medium, in terms of broadcast/download time and navigation/seeking time. It is extremely clear that `metadata' provide the window of access into a digital archive and the quality of digital archive is sine-qua-non with its metadata. NAL's initiatives in following a disciplined and systematic `metadata' approach in archiving and retrieving digital video content of the country's most ambitious civil aircraft programme are highlighted.

Computer applications in different areas of structural engineering such as analysis, design, construction and project management are mostly written in procedure-oriented languages and they are presently fragmented in nature. It is well-recognised that use of integrated computer applications would lead to saving in time and cost in design and construction of structures and infrastructural facilities. Vigorous efforts are being made world-wide to develop methodologies for integration by making use of latest developments in Information and Communication Technologies (ICT) such as object-oriented modeling, information/data exchange standards, integrated data bases, 3-D/4-D modeling, virtual reality, network and world-wide web. Object-oriented modeling is being used in all these technologies to facilitate integration and extensibility. The paper presents an object-oriented framework for integrating legacy computer applications in structural engineering. Details of an object-oriented model for integrating legacy computer applications of analysis and design of RC frames are presented by using the Unified Modeling Language (UML) and the Case Tool : Rational Rose. Working of the OO model has been demonstrated with an example of implementation of integration of legacy structural analysis and design programs for design of an RC frame.

Mobile ad hoc networks (MANETs), which connect individual users to each other, remain a topic of research development in wireless network systems. The data in these systems are transmitted by way of multiple-hops, when the source node is distant from the destination node. These MANETs have been used mainly in military applications such on the battlefield to exchange information about the combat environment between army units. This type of system is faced with not only the usual security problems, but must also work under certain limitations, such as low power and restricted computing ability. Fundamental procedure of constructing the constructing the common key in mathematically geometric property and relevant security problems has been discussed.

Commuter railway services in cities such as Mumbai are characterized by a large number of services admitting short headways of a few minutes between successive services on the same track. So the timetabling of commuter services in railway operations has certain unique features that make it a very challenging task. This paper aims to demonstrate the viable use of constraint ligic programming (CLP), to generate reasonable timetables under a very general framework of constraining conditions. CPL is a powerful programming paradigm which combines the ease of specification and modeling of logical relationships provided by PROLOG, with the general framework of constrained systems specified by linear inequalities. Traditionally, transportation planners have sought to consider the use of timetabling as an optimization problem, with the aim of finding the 'Best' possible timetable, under a set of operating and other constraints. The criterion of "Best" would typically be the maximization of number of services offered, or maximizing the utilization of coaches or minimizing the number of coaches required to operate a certain fixed number of services, etc. This leads to the formulation of complex optimization problems, which are extremely difficult to solve.

Authors have developed and designed H2O (Hackers have Hurdle in breaking the Omega network) algorithm for encryption and decryption. Cryptography provides many methods and techniques for secure communication. Apart from the existence of many techniques, authors have proposed a new technique. To generate the key, bit-level encryption methodologies have been used like substitution, permutation [5]. On focusing the security, along with Shuffle-Exchange (Omega network) [3] the conversion of binary to gray code is done. The key length is 592 bit which is hard to break. These factors strengthen the algorithm. since the block cipher technique is used, the speed of the algorithm is increased. Discusses on how to generate encryption key from which substitution table is constructed and the information is enciphered.

Clustering is one of the most useful tasks in data mining process for discovering groups and identifying interesting distributions and patterns in the underlying data. Clustering problem is about partitioning a given data set into groups (clusters) such that the data points in a cluster are more similar to each other than points in different clusters. However, finding a consensus clustering from graph-based, combinatorial or statistical perspective. conventional clustering algorithms utilize a single criterion to form clusters and such algorithms may not always confirm to the diverse shapes of the underlying clusters. Hence, it is necessary to perform clustering using a combined approach that combines more than one clustering technique in order to provide optimal clusters. Author proposes a new clustering approach that uses the entropy values fo feature selection and to apply weak clustering algorithms. Used the majority voting scheme to obtain optimal clusters from the clusters obtained from the various clustering techniques. The main advantage of this work is to enhance the clustering capability of weak clustering algorithms using the summation of cluster efficiencies in order to reduce the misclassification rate.

Improve wind wave short-term forecasts based on artificial neural networks is reported. The novelty of the study consists in the use of relatively short time series of wave observations collected over 2 consecutive months to accomplish the tasks of wave predictions and data assimilation. Separate neural networks were developed to predict five wind wave parameters, namely, the significant wave height, zero-up-crossing wave period, peak wave period, mean direction at the peak period and directional spreading over intervals of 3, 6, 12 and 24 hours, and to correct these predictions. Data from a directional buoy were used to train and validate the networks. The results of the simulations carried out without and with the proposed methodology were favourably compared to time series of wave parameters estimated in the field. Moreover, time series plots and scatterplots of the wave characteristics as well as statistics show an improvement of the results achieved due to data merging.

Lot of work is focused increasing efficiency by capturing statistical features in the field of information retrieval community. The other dominant approach is to improve the relevance by capturing the semantic and contextual information which is invariably inefficient. Generally the two approaches are assumed to be diametrically opposite. Tried to combine the two approaches by proposing hybrid information retrieval model. The model works in two stages. The first stage is a statistical model and the second stage is based on semantics. Downsized the document collection for a given query using vector model and then used a conceptual graph (CG) based representation to rank the documents. Main objective is to investigate the use of conceptual graphs as a precision tool in the second stage. The use of CGs brings semantic in the ranking process resulting in improved relevance. Three experiments have been conducted to demonstrate the feasibility and usefulness of the model. A test run is made on CACM-3204 collection. Observed 34.8% increase in precision for a subset of CACM queries. The second experiment is performed on a test collection specifically designed to test the strength of our model in situation where the same terms are being used in different context. Improved relevance has been observed. The application of this approach on results retrieved trom L YCOS shown significant improvement. The proposed model is both efficient, scalable and domain independent.

Many argue that the open source software is `free' and free from intellectual property protection clutches. Argues that this notion is a myth when taking into account the percentage of proprietary software usage all over the world. The governmental policies and decision to suppot or adopt one model or the other will have a large impact on the software industry. This study substantiates that the neutrality of government promotes innovation and development rather than supporting a particular model through a cross-country analysis of Europe, Brazil, China and India. The analysis shows that more governments are making laws and policies in support of open source softwares.

Reports the results of a survey conducted at Banaras Hindu University (BHU) to determine the extent to which Internet users are aware and make use of the Internet. Efforts are on to find the information searching habits of Internet users. Data were collected using a questionnaire and follow-up interviews with the Internet users of three institutes and six faculties. Results show that all respondents are using Internet because of quality information they got through the Internet. Majority of respondents use Internet for research work because the university library has provided access to a large number of databases and online journals. Fifty percent of respondents search information through the search engines, whereas thirty-five percent prefer to go through the specific website/URL. Google and Altavista are more widely used search engines compared to others due to their wide coverage and user-friendly interface. About seventy percent of respondents prefer to take print out before making use of Internet material as compared to those who prefer online or CD. Thirty-five percent of respondents believe that Internet is most useful because they find valuable information all the time. It has also been observed that slow speed, high Internet charges, lack of training and lack of organized information are some of the factors that affect the use of Internet. Presents recommendations to improve the use of Internet, including a well planned Internet literacy program and preparation of subject gateways.

Objective of the semantic web is to make the interoperati among web services or between users and web services more automated and flexible. The basic step toward the interoperation is that users or web services can discover their required web service. Practical application on Semantic Web and Web Services concepts where a flexiible and automatic matching procedure in e-Iearning has been shown. How the requirements, web services and domain knowledge are described in machineª understandable forms to support the automatic and flexible discovery of web services is illustrated. Then a match making a lgorithm based on the semantic intormation is proposed. Finally the design and implementation of a prototype for the automatic discovery of web services is described.

With the advent of the Semantic Web as the next-generation of Web technology, large volumes of Semantic Web data described in RDF will appear in the near future. Most previous approaches treat RDF data as a form of triple and store them in a large-sized relational table. Basically, since it always requires the whole table to be scanned for processing a query, it may degrade retrieval performance. In addition, it does not scale well, we propose a hybrid storage approach for RDF data management. The proposed approach aims to provide good query performance , scalability, manageability, and flexibility. To achieve these goals, we distinguish some frequently appeared properties in RDF data. A set of RDF data with a distinguished property is independently treated and stored together in a corresponding property-based table. For processing a query having a specific property, we can avoid full scanning the whole data and only have to access a corresponding table. For queries having specific properties, the proposed scheme achieves better performance than the previous approach.

Web Service is the fitted technical solution which provides the required loose coupling to achieve Service Oriented Architecture (SOA). Authors propose to increase the adaptability of Web Services by using the main AOP agreed semantics - Advices, Pointcuts and Joinpoints- to change original Web Service behavior. In the new approach, authors consider that advices are themselves Web Services. Moreover, authors propose to use an XML Language to describe Pointcuts, Joinpoints and for referencing advices. The invocation of advices (Web Services) is accomplished by an XQuery engine to ensure SOAP Engine independency and advices are implemented as Web Services to promote programming language independency.

Internet Bookshops are the online bookshops that allow the user to search the items of his interest, navigate, make a query, communicate, place an order, bargain and negotiate. At its simplest the Internet Bookshop or online bookshop list the products for sale or the services offered and invite the customer to phone, fax or e-mail their order. The present paper evaluates major ten Internet bookshops by using the evaluation criteria like Authority, variety of collection, help menu, shopping procedures, payment acceptance, special facilities for online purchase, user search support, product details, navigation facilities and discounts on the products. A 100 marks scoring system has been adopted to assign the scores to each Internet bookshop under study. Based on the marks obtained these bookshops are graded into five categories viz. Excellent, Very Good, Good, Average and Poor. Amazon.com, USA and Amazom, UK fall under excellent category while the Internet bookshops from India viz D.K.Agencies and Khemraj fall under good and average category respectively.

Dependability is a major concern in software development, deployment, and operation. A commonly accepted solution for providing fault tolerant services on the Internet is to create replica of the services and to deploy them to several hosts. Whenever the service or the underlying node or network fails, another service is ready to take over. In the Venice! project, several techniques are combined to create a dependable framework for deploying and managing distributed services using replica on several distinct network nodes.
