It includes the technical and organizational obstacles, the role of standards, and some promising recent developments for overcoming the obstacles. Particular attention is paid to the IHE (Integrating the Healthca...

Everyone in our society must obey law. Similarly, in esociety, information systems which play the role of enforcing law must obey law. A law usually defines its purpose, conditions, and activities/procedures. In this paper, we propose a concept of Software Accountability of Law Enforcing Information Systems (LEISs) and show its realization method. Software accountability is that a LEIS itself c...

The paper describes so-called “Methodology Framework for Information Systems Development”. It has been developed at the Department of Information Technologies of the University of Economics in Prague, Czech Republic, and its development still continues. Moreover, the development of this facility is intended as the never ending process – the process of international collaboration and experience ...

We present a new approach for handwritten signature classification and verification based on descriptors stemming from time causal information theory. The proposal uses the Shannon entropy, the statistical complexity, and the Fisher information evaluated over the Bandt and Pompe symbolization of the horizontal and vertical coordinates of signatures. These six features are easy and fast to compu...

Digital imaging devices, computer-based image-management systems, and radiology information systems (RIS) are the three building blocks that serve as the foundation for the all-digital practice of radiology (1). In the first instance, these digital technologies have been used simply to replace the analog imaging systems and the manual information and film-handling systems, used historically for...
