In this paper, we proposed a scheme to implement ‘Electronic Voting’ an important application of Blind digital Signature using elliptic curve cryptographic algorithm. The selection of this algorithm is its difficulty in solving it. The algorithm is used in combination with the blinding factor to scramble the contents of the message to be signed by the signer so that the signer do not come to kn...

In this short paper, we address the numerical simulation of the single reed excitation mechanism. In particular, we discuss a formalism for approaching the lumped nonlinearity inherent in such a model using a circuit model and the application of wave digital filters (WDFs), which are of interest in that they allow simple stability verification, a property which is not generally guaranteed if on...

PURPOSE The purpose of this study is to compare the visibility of microcalcifications of digital breast tomosynthesis (DBT) and full-field digital mammography (FFDM) using breast specimens. MATERIALS AND METHODS Thirty-one specimens' DBT and FFDM were retrospectively reviewed by four readers. RESULTS The image quality of microcalcifications of DBT was rated as superior or equivalent in 71.0...

This study identifies factors underlying the digital divide that is faced by the disabled. The results of its analysis showed that the digital divide in PC use is affected by age, number of years of education, employment status, and household income of more than KRW 3 million. The digital divide in smart device use is affected by sex, age, number of years of education, time when disability stru...

In this article we give a survey of the current practice and state-of-theart of recommender services in scientific digital libraries. With the notable exception of amazon.com and CiteSeer which do not qualify as proper scientific libraries our survey revealed that in scientific libraries recommender services are still not in wide use – despite the considerable benefits they offer for students a...

One of the greatest challenges in higher education is to give billions of impoverished people access to it across the globe. The growth of information and communications technologies (ICTs) over the past decade holds great promise for meeting this challenge, yet the limited access that most of the world's population still has to such technologies constitutes its own challenge as well. Can we co...

1. MOTIVATIONS The mission of the international workshop series on Very Large Digital Libraries (VLDLs) is to provide researchers, practitioners and application developers with a forum fostering a constructive exchange among all key actors in the field of Very Large Digital Libraries. Its long-term and ambitious goal is to discuss the foundations of VLDLs and establish it as a research field on...

|We describe a system for browsing and interactively retrieving video over the Internet at multiple spatial and temporal resolutions. The VideoZoom system enables users to start with coarse, low-resolution views of the sequences and selectively zoom-in in space and time. VideoZoom decomposes the video sequences into a hierarchy of view elements, which are retrieved in a progressive fashion. The...

With the huge amount and large variety of information available in a digital library, it’s becoming harder and harder for users to identify and get hold of their interested documents. To alleviate the difficulty, personalized recommendation techniques have been developed. Current recommendation techniques rely on similarity between documents. In our work, recommendations are made based on three...

The increasing availability of a wide variety of digital libraries provides a heterogeneous population of users with access to a heterogeneous collection of data. To help users find interesting items from this huge volume of available information, personalization systems allow users to directly or indirectly indicate preferences. Such preferences may depend on context, for instance, on the devi...
