One of the major issues in Robotics or more precisely in Intelligent Systems in current research and innovation is self awareness. The world of innovation in Robotics has been developing autonomous robots with the ability to reason, learn and accomplish basic tasks. Self mapping is one of these abilities and it is very crucial to any physical agent that claims to be aware of its environment. To...

Making Domain-Specific Modeling Languages a part of a tool chain, a part of a proven development process, or the subject of verification cannot be achieved without the precise specification of the language and the models expressed in it. Defining formal semantics for modeling languages is a widely accepted solution to this problem. We have developed methods, techniques and processes to provide ...

Conceptual-relational mappings between conceptual models and relational schemas have been used increasingly to achieve interoperability or overcome impedance mismatch in modern data-centric applications. However, both schemas and conceptual models evolve over time to accommodate new information needs. When the conceptual model (CM) or the schema associated with a mapping evolved, the mapping ne...

We examine the problem of mapping a Boolean network using gates from a finite size cell library. The objective is to minimize the total gate area subject to constraints on signal arrival time at the primary outputs. Our approach consists of two steps: In the first step, we compute delay functions (which capture gate area – arrival time tradeoffs) at all nodes in the network, and in the second s...

BACKGROUND Catheter ablation of ventricular tachycardia (VT) is still one of the most challenging procedures in cardiac electrophysiology, limited, in part, by unmappable arrhythmias that are nonsustained or poorly tolerated. Calculation of the inverse solution from body surface potential mapping (sometimes known as ECG imaging) has shown tremendous promise and can rapidly map these arrhythmias...

NMR is very well suited to the study of especially weak protein-protein interactions, as no crystallization is required. The available NMR methods to this end are reviewed and illustrated with applications from the recent biochemical literature: intermolecular NOEs, cross-saturation, chemical shift perturbation, dynamics and exchange perturbation, paramagnetic methods, and dipolar orientation. ...

The importance of interoperability among computer systems has been progressively increasing over the last years. The tendency of current cataloguing systems is to interchange metadata in XML according to the specific standard required by each user on demand. According to the research literature, it seems that there exist two main approaches in order to tackle this problem: solutions that are ba...

BACKGROUND One of the primary obstacles to the widespread adoption of openEHR methodology is the lack of practical persistence solutions for future-proof electronic health record (EHR) systems as described by the openEHR specifications. This paper presents an archetype relational mapping (ARM) persistence solution for the archetype-based EHR systems to support healthcare delivery in the clinica...

Following the publication of the original article [1], it was brought to our attention that citation number 20 had been truncated. At current the reference reads as: ‘20. Freire SM, Sundvall E, Karlsson D, Lambrix P. Performance of XML Databases for Epidemiological Queries in Archetype-Based EHRs. 2012:51–57.’ However, it should instead read as: ‘20. Freire SM, Sundvall E, Karlsson D, Lambrix P...
