ProteinScanAR - An Augmented Reality Web Application for High School Education in Biomolecular Life Sciences
2012
Understanding protein structures is a crucial step in creating molecular insight for researchers as well as students and pupils. The enormous scaling gap between an atomic point of view and objects in daily life hampers developing an intuitive relation between them. Especially for high school students, it can be difficult to understand the spatial relations of a protein structure. Due to lack of direct imaging techniques, molecules can only be explored by studying abstract molecular models. Here, the use of Augmented reality (AR) techniques has proven to strongly improve structural perception. In this work we present ProteinScanAR, an augmented reality framework for biomolecular education t…
Wartość informacji w systemie informacyjnym w ocenie jej jakości
2018
The purpose of the article is to determine to what extent and how to evaluate the value of information available in the information system when assessing its quality. Such an evaluation, especially for systems operating on the Internet, is absolutely necessary because of the constant and rapid growth of the information resources available there, bearing the unnecessary economic costs of their poor quality and related to that negative social phenomena. The quality of information is a multidimensional category and requires evaluation of great number of different attributes. Are there among conceptual models for evaluating the quality of information also such that require evaluating the value …
Factors Affecting E-Business Adoption by SMEs in Sub-Saharan Africa
2009
The use of information communication technologies (ICT) especially the Internet by small- and medium-sized enterprises (SMEs) is on the increase in many regions of the world, including Africa. Nevertheless, empirical evidence from Sub-Saharan Africa (SSA) regarding the factors that affect the adoption of e-business is scarce. In that regard, the main objective of this chapter is to fill the research gap with an exploratory study that is aimed at eliciting views from SMEs in Nigeria. This article made use of a theoretical framework encompassing organizational, external and technological contexts to deliberate the issue. A survey is conducted in three Nigerian cities and the findings of the s…
Some reflections on non-contractual obligations in cyberspace considering the Rome II regulation
2014
Internet penetration has created a revolutionary change in people's communication nowadays. By creating immaterial and elusive cyberspace, without borders and limits of communication a three-dimensional territorial concept has been transformed by globalizing social relations and reducing importance of regional or national dimensions. All situations taking place on the Internet also occur somewhere in the reality. Sometimes it is difficult to measure whether the events are random or unrelated to particular events. Technological progress offers new possibilities to change a user's real location either consciously or subconsciously. However, the law is highly territorial in nature. This articl…
Audiovisual accessibility on the web: subtitling in the European Parliament
2020
El presente trabajo pone de relevancia la importancia de la accesibilidad en la sociedad de la información actual, en concreto, en Internet, por lo que analizaremos el cumplimiento de los requisitos de accesibilidad a los contenidos audiovisuales establecidos por las Pautas de Accesibilidad al Contenido Web (WCAG) 2.0 en el canal de televisión online EuroparlTV. Asimismo, trazaremos el vínculo inherente entre la accesibilidad web y la audiovisual y describiremos los subtítulos generados por profesionales de la traducción en el ámbito institucional, concretamente en el Parlamento Europeo. Para llevar a cabo nuestro objetivo y poder realizar el estudio sistemático y exhaustivo de distintos as…
Internet Lite for Sustainable Development
2018
The Digital Divide is one of the key challenges for mankind. Despite attempts to digitally include people, the divide is bigger than ever. This contribution [1] to a sustainable future promotes “Internet lite” as the new paradigm for providing everyone with the opportunity to participate in the digital society. The current paper first addresses the reasons for the digital divide, thereafter addresses free access to information as catalyst for the sustainable development goals (SDGs) and provides the path towards “Internet lite for all”.
A holistic framework for understanding acceptance of remote patient management (RPM) systems by non-professional users
2010
The successful integration of Information and Communication Technologies (ICT) in healthcare facilitates the use of the sophisticated medical equipment and computer applications by medical practitioners. If earlier medical systems were mainly used by the health professionals (e.g. medical staff or nurses), nowadays with the appearance of Internet health systems are becoming available to the broader user groups, particularly patients and their families. eHealth has become an active research and development area within healthcare industry. Another important tendency in the development of ICT for health is a shift from “hospital-centered” to “person-centered” health systems which can enable ma…
The Public-Key-Infrastructure of the Radiological Society of Germany.
2005
Pretty Good Privacy (PGP) encoding is based on the Public-Key-Procedure and permits the safe transmission of medical data. Furthermore it allows the use of an electronic signature provided that keys used belong to the key owner and that the key owner's identity is guaranteed by a trusted third party. Under the auspices of the Radiological Society of Germany (Deutsche Rontgengesellschaft, DRG) its IT-Working Group (Arbeitsgemeinschaft fur Informationstechnik, @GIT) built up an appropriate Certification Authority including the required Public-Key-Infrastructure. These @GIT certified PGP keys allow the legal use of telemedicine in Germany. Digital signatures based to those certified keys corre…
The heterogeneity of inter-domain Internet application flows: entropic analysis and flow graph modelling
2013
The growing popularity of the Internet has triggered the proliferation of various applications, which possess diverse communication patterns and user behaviour. In this paper, the heterogeneous characteristics of Internet applications and traffic are investigated from a complex network and entropic perspective. On the basis of real-life flow data collected from a public network provided by an Internet service provider, flow graphs are constructed for five types of applications as follows: Web, P2P Download, P2P Stream, Video Stream and Instant Messaging. Three types of entropy measures are introduced to the flow graphs, and the heterogeneity of applications within a 24-h period is analysed …
Online Induction of Probabilistic Real Time Automata
2012
Probabilistic real time automata (PRTAs) are a representation of dynamic processes arising in the sciences and industry. Currently, the induction of automata is divided into two steps: the creation of the prefix tree acceptor (PTA) and the merge procedure based on clustering of the states. These two steps can be very time intensive when a PRTA is to be induced for massive or even unbounded data sets. The latter one can be efficiently processed, as there exist scalable online clustering algorithms. However, the creation of the PTA still can be very time consuming. To overcome this problem, we propose a genuine online PRTA induction approach that incorporates new instances by first collapsing…
