Multilingual Computing in Malayalam : Embedding the Original Script of Malayalam in Linux and Development of KDE Applications
(INFLIBNET Centre, 2005-01-02) J S, Rajeev; R, Chitrajakuma; K H, Hussain; N, Gangadharan
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.
Challenges of Multimedia Watermarking Techniques
(INFLIBNET Centre, 2005-02-02) Jayabalan, E.; Krishnan, A.; Pugazendi, R.
Data transmitted through a network may be protected from unauthorized receivers by applying techniques based on cryptography. Only people who possess the appropriate private key can decrypt the received data using a public algorithm implemented either in hardware or in software. Fast implementation of encryption-decryption algorithms is highly desirable. Data-content manipulation can be performed for various legal or illegal purposes (compression, noise removal or malicious data modification). The modified product is not authentic with respect to the original one. The technology of multimedia services grows rapidly, and distributed access to such ser-vices through computer networks is a matter of urgency. However, network access does not protect the copyright of digital products that can be reproduced and used illegally. An efficient way to solve this problem is to use watermarks. A watermark is a secret code described by a digital signal carrying information about the copyright property of the product. The watermark is embedded in the digital data such that it is perceptually not visible. The copyright holder is the only person who can show the existence of his own watermark and to prove the origin of the product Reproduction of digital products is easy and inexpensive. In a network environment, like the Web, retransmission of copies all throughout the world is easy. The problem of protecting the intellectual property of digital products has been treated in the last few years with the introduction of the notion of watermarks.

Analysis and Synthesis for Pyramid Based Textures
(INFLIBNET Centre, 2005-02-02) Karthikeyani, V; Duraiswamy, K; Kamalakkannan, P
This paper describes a method for synthesizing images that match the texture appearance of a given digitized sample. This synthesis is completely automatic and requires only the “target” texture as input. It allows generation of as much texture as desired so that any object can be covered. It can be used to produce solid textures for creating textured 3-d objects without the distortions inherent in texture mapping. It can also be used to synthesize texture mixtures, images that look a bit like each of several digitized samples. The approach is based on a model of human texture perception, and has potential to be a practically useful tool for graphics applications.
An Improved Hybrid Routing Protocol for Mobile Ad Hoc Networks
(INFLIBNET Centre, 2005-02-02) Kamalakkannan, V; Karthikeyani, V; Krishnan, A
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.
Streaming Communication for Web Based Training
(INFLIBNET Centre, 2005-02-02) Pugazendi, R; Krishnan, A.; Jayabalan, E
Streaming audio became available on the Web in 1995, but with the development of the Synchronized Multimedia Integration Language (SMIL), the technology has reached a new level of maturity. SMIL is based on the XML standard, and allows audio, video, images, and text to be integrated. The implications for Web based pedagogy are tremendous. We now have the opportunity to do training on the desktop in a feature-rich open environment. We will give a basic background in streaming media technology, discuss the standards, the current state of the art, our experience with RealNetworks, how to take advantage of it in an intranet environment, and touch on future developments, including the integration of testing engines.
A Document Reconstruction System for Transferring Bengali Paper Documents into Rich Text Format
(INFLIBNET Centre, 2005-02-02) Chaudhuri, Anirban Ray; Singh, Debnath; Nasipuri, Mita; Basu, Dipak Kumar
The transformation of a scanned paper document into an editable form suitable for further processing such as desktop publishing or archiving in a digital library is a complex process. It requires solutions to several problems – document analysis by acquiring knowledge of document layout by a Page Layout Analyzer (PLA), followed by document recognition, which mainly comprises text recognition by Optical Character Recognition (OCR). Besides these two, another important problem is document reconstruction by transforming content into an electronically editable format by keeping the original layout intact. Core OCR modules exist on different Indian scripts, but no such document reconstruction system is available for Indian scripts. The document reconstruction system reported in this paper is the first of its kind on Indian scripts and it addresses document reconstruction for Bengali document images. The system makes use of the knowledge of both document layout extracted by a PLA in a graphical user interface (GUI) and the results of text recognition steps performed by OCR for transformation of paper documents into Rich Text Format.
Mutual Authentication Protocol For Safer Communication
(INFLIBNET Centre, 2005-02-02) Shantharajah, S P; Duraiswamy, K
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.

Temporal Association Rule Using Without Candidate Generation
(INFLIBNET Centre, 2005-02-02) Verma, Keshri; Vyas, O P
Associationship is an important component of data mining. In real world, the knowledge used for mining rule is almost time varying. The items have the dynamic characteristic in terms of transaction, which have seasonal selling rate and it holds time-based associationship with another item. In database, some items which are infrequent in whole dataset may be frequent in a particular time period. If these items are ignored then associationship result will no longer be accurate. To restrict the time based associationship, calendar based pattern can be used [5]. Calendar units such as months and days, clock units, such as hours and seconds & specialized units , such as business days and academic years, play a major role in a wide range of information system applications.[11] Our focus is to find effective time sensitive algorithm for mining associationship by extending frequent pattern tree approach [3]. This algorithm reduces the time complexity of existing technique[5]. It also uses the advantages of divide & conquer method to decompose the mining task into a smaller tasks for database.

(INFLIBNET Centre, 2005-02-02) Sahu, Hemant Kumar
There is an enormous range of available information in the world. In electronic environment many libraries have created a presence on the Web, but have we really thought about why we want to be there? Should library Web sites be grounded in the past or look forward to the future, or both? This paper has tried to focus on various issues related to the object and importance of the library homepage, how to create, what is requirement etc for library homepage. The role of the library is to select, acquire, organize and make available an appropriate subset of this information. Proving electronic information to its users has become a common feature of many special libraries through their homepages. A case study of IUCAA library’s homepage is presented. It discusses how IUCAA Library has taken challenges of the new emerging technologies and increasing demands of its users by adopting electronic information sources and services and how it generates value added electronic information for its users. This paper also describes the important electronic sources in astronomy & astrophysics, which is used in IUCAA library.

vascoda (www.vascoda.de) is a new portal for scientific information – it is the nucleus of the German digital library. vascoda is a central access point for interdisciplinary searches ranging from humanities and social sciences to medical studies, engineering, and more. Access to all types of documents is made possible: born-digital as well as digitised and print materials can be obtained either free of charge or through pay-per-view options. The service already includes full-texts, link-collections, databases, subject-specific search engines and more. More than forty German institutions – mostly libraries and other information specialists are working together to offer users an actual one-stop-shop for all scientific information. The first release of vascoda was realized through the co-operation of the network of subjectbased Virtual Libraries sponsored by the DFG (German Research Society) as well as the Information Alliance and the Electronic Journals Library sponsored by the BMBF (Federal Ministry for Education and Research). Together, these institutions make it possible to combine the search for information and the access to full-text documents. Some of the journal articles and other documents can be accessed free of charge from anywhere in the world, the licence information for Germany is provided by the Electronic Journals Library and other partners. In this paper, the services of vascoda and examples of how to find quality information for different fields of study will be presented. In spring 2005, a number of new services will be provided. This paper will also look into some of the future developments of vascoda.

A Novel Approach for Document Image Mosaicing Using Wavelet Decomposition
(INFLIBNET Centre, 2005-02-02) Shivakumara, P; Kumar, G Hemantha; Guru, D S; Nagabhushan, P
There are some situations where it is not possible to capture or scan a large document with given imaging media such as scanner or Xerox machine as a single image in a single exposure because of their inherent limitations. This results in capturing or scanning a large document image into number of split components of a document. Hence, there is a need to mosaic the several split components into a single large document image. In this work, we present a novel and simple approach for mosaicing the two split document images using wavelet decomposition to generate single and large document image. The proposed method uses the wavelet decomposition to speed up the mosaicing process by means of Multi Resolution Analysis (MRA). The pixel based and Column –Block matching procedures are used here to identify the overlapping region in the split images. The overlapping region is a common region which helps in obtaining mosaiced image from its split images. The proposed methods work based on assumption that the overlapping region is present at the right end of split image1 and at the left end of split image2
