In this paper, we discuss security aspects of interactive bilateral multi-attribute negotiations. We introduce this type of electronic negotiations and maintain that it will be an important functional aspect of business-to-business electronic marketplaces. We discuss the general application architecture and the process flow for this type of negotiations. We introduce the relevant security issue...

It is estimated in a recent OECD International Adult Literacy Survey that up to 500,000 Irish adults are functionally illiterate, that is many people have difficulty in reading and understanding everyday documents. We address this problem by allowing users to interact with speech enabled e-Learning literacy content using multimodal interfaces. We present two experimental prototypes that explore...

In ubiquitous computing applications, mobile participants must be empowered to opportunistically connect to services available in their local environments. Our previous work has elucidated a model for allowing applications to specify the functional properties of the services to which they need to connect. Our framework then connects applications to dynamic resources through the use of a novel s...

Over two years after launching The Guide to Canadian Museums and Galleries, the Cana-dian Heritage lnformation Network (CHIN) initiated the redesign of this collaborative, online resource dedicated to promoting Canadian museums. This project involved more than a simple facelift. It involved interdisciplinary research to define the user interface redesign that might transform the Guide into a si...

Urban intersections are the most dangerous parts of a blind or visually impaired pedestrian's travel. A prerequisite for safely crossing an intersection is entering the crosswalk in the right direction and avoiding the danger of straying outside the crosswalk. This paper presents a proof of concept system that seeks to provide such alignment information. The system consists of a standard mobile...

objective(s): this paper describes coating of magnetite nanoparticles (mnps) with amorphous silica shells.   materials and methods: first, magnetite (fe3o4) nps were synthesized by co-precipitation method and then treated with stabilizer molecule of trisodium citrate to enhance their dispersibility. afterwards, coating with silica was carried out via a sol-gel approach in which the electrostati...

the years 1895 to 1898 were momentous for their impact on health and human well beings. first, wilhelm roentgen noted a glowing fluorescent screen, caused by invisible rays. this event subsequently led to the discovery of x-rays in 1895, and thus the birth of the “atomic age”. next becquerel’s investigations of these mysterious rays led to his experiments with uranium salt crystals. he thought ...
