One of the challenging problems of pervasive computing is to link a physical object with digital information because many of the pervasive computing applications require manual inputs or complex image processing to obtain information related to a real object. The use of 2D barcodes eliminates such excess processing to acquire the needed information. The 2D barcodes have high capacity to store d...

A 1.5 mm magnetic sphere was navigated automatically inside the carotid artery of a living swine. The propulsion force, tracking and real-time capabilities of a Magnetic Resonance Imaging (MRI) system were integrated into a closed loop control platform. The sphere was released using an endovascular catheter approach. Specially developed software is responsible for the tracking, propulsion, even...

Modeling and regulating interactions among agents is a critical step in the development of Multiagent Systems (MASs). Some recent works assume a normative view, and suggest to model interaction protocols in terms of obligations. In this paper we propose to model interaction protocols in terms of goals and commitments, and show how such a formalization promotes a deliberative process inside the ...

Globalisation is bringing translation and multilingual information processing to areas where it was previously unknown or relatively unimportant. Today, translation is not only important for reaching global audiences, it is becoming an indispensable component inside other systems and workflows. MALT (Modular Architecture for Linguistic Tools) represents a fresh approach to a relatively new prob...

We present a vortex method for the simulation of the interaction of an incompressible flow with rigid bodies. The method is based on a penalization technique where the system is considered as a single flow, subject to the Navier–Stokes equation with a penalization term that enforces continuity at the solid–fluid interface and rigid motion inside the solid. Level set functions are used to captur...

The aim of this chapter is to investigate the potential role of social software inside business settings in integrating knowledge exploitation and knowledge exploration strategies. These strategies are approached through the lens of dynamic capabilities, organisational learning and knowledge lifecycle models. The authors argue that while current enterprise Information Technology (IT) systems fo...

Introduction/Purpose An image-based localization of interventional tools or devices inside the magnet requires adequate, MR-visible markers and a powerful image processing tool to automatically detect them. In contrast to active tracking techniques, a substantial amount of time is needed for the acquisition of the marker images alone. In this work, a marker sequence at low spatial resolution wa...

One of the problems related to sensor networks built up from large number of nodes having limited capabilities is the operating system running inside each node. It must provide a lot of functionality and allow easy development of applications, but has very restricted resources (like memory, processing capabilities, and energy). Some of the features are also related to the general nature of the ...

Living organisms demonstrate through millions of years evolution remarkably fault-tolerance, robustness and self-healing abilities. Taking inspiration from biological immune systems and embryonic processes which acquire some of these fault-tolerant properties, the paper presents the implementation of an embryonic machine with FPGA-based multi cellular architecture, which is able to imitate cell...
