Abstract: The potentialities of information technology, together with economic concerns, have been forcing various organizations to go for digitization. This has also happened to libraries, whose primary value lies not only in their collections but also in their contribution to education through providing information service, facilities for e-learning and management of collected information, which they make easily usable and accessible to users. The design and development of web-based educational systems for people is happening in India also. URI: http://hdl.handle.net/1944/1560 Files in this item: 1

Abstract: A novel routing scheme for mobile ad hoc networks (MANETs), which combines the ondemand routing capability of Ad Hoc On-Demand Distance Vector (AODV) routing protocol with a distributed topology discovery mechanism using ant-like mobile agents is proposed in this paper. The proposed hybrid protocol reduces route discovery latency and the end-toend delay by providing high connectivity without requiring much of the scarce network capacity. On the one side the proactive routing protocols in MANETs like Destination Sequenced Distance Vector (DSDV) require to know, the topology of the entire network. Hence they are not suitable for highly dynamic networks such as MANETs, since the topology update information needs to be propagated frequently throughout the network. These frequent broadcasts limit the available network capacity for actual data communication. On the other hand, on-demand, reactive routing schemes like AODV and Dynamic Source Routing (DSR), require the actual transmission of the data to be delayed until the route is discovered. Due to this long delay a pure reactive routing protocol may not be applicable for real-time data and multimedia communication. Through extensive simulations in this paper it is proved that the proposed Ant-AODV hybrid routing technique, is able to achieve reduced end-to-end delay compared to conventional ant-based and AODV routing protocols.

Abstract: The idea of E- Theses and Dissertations (ETD) is coming up in International scenario, which can be easily located, readily accessible and delivered over the web. This paper analyzing the opinions of selected Ph D Researchers and Guides from selected Indian Universities on Copyright and IPR issues related to ETDs. On the basis of the output, the paper suggests that Universities can start collecting e-format of theses, creating a digital archive for easy access. But in terms of access, still only a minimum majority is favoring online global access to Indian research. This may be because of Copy Right Issues, Chances of Plagiarism and Poor Quality in Research, which may be solved through policy frameworks and enhancing standards through national agencies like UGC at national level.

Abstract: Big deal or the consortia site licensing is the most preferred way of e-journal subscription for Indian Consortia be it INDEST or the UGC Infonet. In the big deal model all the journals published by a publisher or hosted by an aggregator on its web site are made available to the consortia members at a so called “highly reduced” price. It has been seen that the librarians throughout the world haves been raising objections to this mode since beginning. There are various concerns which have been identified such as monopoly of the publishers, use of a limited number of titles, effect of citation ranking of journals published by the small publishers and the fear of death of journals published by the developing countries. Though a number of articles have been published on this topic but most of them have been on the qualitative aspects of such deals. There are a few studies that have been conducted on quantitative aspects. In this paper a study of use of Elsevier’s ScienceDirect at IIT Roorkee has been presented which clearly shows that a very limited number of titles are frequently used in the Institute. This data clearly indicates that the Big Deal mode of subscription is not at all in the favour of the consortia. Supports an alternate model for subscription which should be based on the fixed fee access to the limited set of journals which are frequently used and pay for use for the journals which are less frequently used.

Abstract: The present approach towards partnership, networking, consortia and resource sharing adopted by Indian libraries need radical changes to evolve responsive partnerships in order to achieve best performance in service. The current practices of journal acquisition in most of the libraries in the colleges and universities in India are print based, in which each library is an island with regard to access of information. Moreover, there is wide disparity in the availability and use of information among different universities and colleges. But, consortia based acquisition and electronic desktop delivery of information can eliminate this gulf and increase the access and use considerably. Thus the difficulty now faced by the students, teachers and scientists in getting academic and research information will be eliminated on achieving full bibliographical control on the information documents available world over. This paper depicts the benefits of library consortia, analyses the present trend in the formation of consortia in India and suggests a new model of library consortia in which all academic institutions and government research organizations could participate. The formation of such a unique consortium under the direction and full support by the Government of India is stressed. The role that can be played by the INFLIBNET Centre of the University Grants Commission in the formation and management of such a consortium is also depicted. The areas of re-defining and re-engineering the operations of the university libraries necessitated by the consortia based electronic information and document delivery services are also discussed.

Abstract: The explosion of information on the Internet and information technology in general has created challenges for libraries to focus on developing more effective ways to meet the information needs of users. One practical approach is through customized portals performing simultaneous database searching. This paper presents a new library portal service used at the Indian Statistical Institute Library at Bangalore (ISIB). The key feature of a library portal is to allow searching across multiple databases without having repeat search. This feature is generally referred to as meta-search, parallel search, broadcast search or federated search. Discussion also includes strategies of local customization and the impact on library management in an electronic environment. URI: http://hdl.handle.net/1944/1558 Files in this item: 1

Abstract: Correlated The discovery of association rules is an important problem in data mining. It is a two-step process consisting of finding the frequent itemsets and generating association rules from them. Most of the research attention is focused on efficient methods of finding frequent itemsets because it is computationally the most expensive step. This paper presents a new data structure and a more efficient algorithm for mining frequent itemsets from typical data sets. The improvement is achieved by scanning the database just once and by reducing item traversals within transactions. The performance comparisons of the algorithm against the fastest Apriori implementation and the recently developed H-Mine algorithm are given here. These results show that the algorithm outperforms both Apriori and H-mine on several widely used test data sets. URI: http://hdl.handle.net/1944/1536 Files in this item: 1

Abstract: Correlated pattern mining has become increasingly important recently as an alternative or an augmentation of association rule mining. Though correlated pattern mining discloses the correlation relationships among data objects and reduces significantly the number of patterns produced by the association mining, it still generates quite a large number of patterns. This paper proposes closed correlated pattern mining to reduce the number of the correlated patterns produced without information loss. A new notion of the confidenceclosed correlated patterns is proposed first, and then an efficient algorithm is present, called CCMine, for mining those patterns. Confidence closed pattern mining reduces the number of patterns by at least an order of magnitude. It also shows that CCMine outperforms a simple method making use of the traditional closed pattern miner. Confidence-closed pattern mining is a valuable approach to condensing correlated patterns.

Abstract: While English has predominantly maintained its lead both as the lingua franca of the Internet and also for basic man-machine interactions, the need of the day is a system that can cater to the native by facilitating such communication in the language he is most comfortable. This calls for the realization of Multilingual Systems that can present the same information in a variety of languages. The term Multilingual Computing in the present context refers to systems that are capable of running programs that accept, process and present data in more than one natural language. The concerned language for interacting with the computer may be selected at the time of invocation or use of the program. Such multilingual systems do not fully overcome the man machine barrier. The user still has to comprehend and react to the cryptic messages presented in the language of his choice. The problem can be overcome only by the use of natural language processing systems that can translate user commands and queries in his native language to machine level commands, facilitate execution and present the results in a manner that is very akin to the responses of a human being. This paper discusses the basic issues in the formulation of such multilingual systems. URI: http://hdl.handle.net/1944/492 Files in this item: 1

Abstract: Indic Language Computing can be fully realized only through embedding vernacular scripts in operating systems. With the advent of OTF (Open Type Font) embedding local scripts in OS compliant with Unicode has become a reality taking computing beyond word processing. Microsoft has already come to this field strongly by embedding Devanagari in MS Windows. Compared to the closedness of Microsoft OS, free and open environment of Linux is ideal for the early accomplishment of multilingual computing. This paper describes initiatives of Rachana team in embedding Malayalam script in GNU/Linux operating system. Modules are added for KDE with its rendering engine QT so that the original exhaustive character set of Malayalam developed by Rachana is embedded fully in compliance with Unicode. For the first time, prospects are open to create DBMS and information systems using Malayalam script. Computing in Malayalam language is being initiated in the true sense only now. The procedures set up by Rachana-GNU/Linux is highly beneficial to the goals of INFLIBNET in fulfilling a total integrated bibliographic control of Indian literature in their native scripts.

Abstract: With a network communication requires cryptography authentication for secure transmission. This paper takes two challenge-response protocols by which entities may authenticate their identities to one another in a mutual communication way. Here the two entities, each holding a share of a decryption exponent, collaborate to compute a signature under the corresponding public key. These may be used during session initiation, and at any other time that entity authentication is necessary. The authentication of an entity depends on the verification of the claimant’s binding with its key pair and the verification of the claimant’s digital signature on the random number challenge. The network defined mutually authenticated protocols are for entity authentication based on public key cryptography, which uses digital signatures and random number challenges. Authentication based on public key cryptography has an advantage over many other authentication schemes because no secret information has to be shared by the entities involved in the exchange. This paper analyzes the protocols, which minimizes cost, very simple and suggests security for mutually signing the signature schemes and provides proofs of security for the safer communication. This paper specifies the way of mutual communication and the method of processing that conversation between entities. URI: http://hdl.handle.net/1944/1544 Files in this item: 1

Abstract: The UniFrame approach to component-based software development assumes that concrete components are developed from a meta-model, called the Unified Meta- component Model, according to standardized business domain models. Implicit in this development is that there is a Platform Independent Model (PIM) which is transformed into a Platform Specific Model (PSM) under the principles of Model-Driven Architecture. This paper advocates natural language as the starting point for developing the business domain models and the meta-model and shows how this natural language may be mapped through the PIM to PSM using a formal system of rules expressed in Two-Level Grammar. This allows software requirements to be progressed from business logic to implementation of components and provides sufficient automation that components may be modified at the model level, or even the natural language requirements level, as opposed to the code level.

Abstract: In order to bridge the digital divide between the sightless and sighted and to encourage literacy in them, we have designed an architecture for transcribing Braille from optically recognized Indian language. The system will help to convert masses of information in different Indian languages into a tactile reading form. The system mainly consists of OCR modules designed in an efficient manner to promote portability and scalability. In first section, we have introduced the importance and necessity of the work with successive sections clarifying briefly the properties of Braille and Indian scripts. We have also described the OCR work done with respect to Indian languages and the related work to our system. Finally, the System architecture is explained clearly followed by some conclusion and future work. The paper also identifies the needs to be fulfilled to percolate the benefit of the technology developed to the masses. URI: http://hdl.handle.net/1944/494 Files in this item: 1
