Parameter mapping sonification is the most widely used technique for representing multi-dimensional data in sound. However, it is known to be unreliable when used for detecting information in some types of data. This is generally thought to be the result of the co-dependency of the psychoacoustic dimensions used in the mapping. Positing its perceptual basis in a theory of embodied cognition, the most common approach to overcoming this limitation involves techniques that afford the interactive exploration of the data using gross body gestures. In some circumstances, such exploration is not possible and, even when it is, it may be neither necessary nor sufficient. This article explores some other possible reasons for the unreliability of parameter mapping sonification and, drawing from the experience of expressive musical performance, suggests that the problem lies not in the parametric approach per se, nor in the lack of interactivity, but in the extent to which the parameters employed contribute to coherent gestalts. A method for how this might be achieved that relies on the use of micro-gestural information is proposed. While this is speculative, the use of such gestural inflections is well known in music performance, is supported by findings in neuroscience and lends itself to empirical testing. © 2014 Cambridge University Press.

The topic "Theragnostics in the Operating Theatre Closed-Loop Diagnostics and Surgery" was discussed based on 15 scientific lectures held at the 7.Symposium "Hospital of the Future" on March16th, 2011, in Munich. The symposium was organized by the DGBMT - German Society for Biomedical Engineering, the Fraunhofer Society and the SMIT - Society for Medical Innovation and Technology. The symposium was completed by a multi disciplinary panel discussion that focussed on chances and limitations of closed-loop-systems in operating theatres. In summary the discussion showed, that there is a significant potential for using closed-loop-systems in operating theatres and the technological possibilities have not been completely utilized yet. However, the surgeon as the human part of the control circuit will not be substituted in near future. An important requirement for the successful implementation of closed-loop-concepts in the operating theatre is the generation of adequate multi-disciplinary competence in both fields, technological development and clinical application. © Georg Thieme Verlag KG Stuttgart · New York.

Computed tomography (CT) can be used for dimensional measurement. Reliable results require an effective artefact correction. In two earlier papers a Synchronous Artefact Correction (German: Einsatzsynchrone Artefakt-Reduktion EAR) was introduced. In this paper some further developments of EAR are given though the key concept isn't altered. It is still two-staged with a separation in fine and coarse registration, the latter is subdivided into translation and rotation. For the coarse rotation the idea of the Overall Cachment Area is applied. In-depth tests favoured "Normalized Mutual Information" that was only second-best in the prime research. Another topic is the analysis of the accuracy of the registration result concerning the applied similarity measure. In this test "Normalized Mutual Information" was figured out to be the measure with the highest accuracy. © Oldenbourg Wissenschaftsverlag. Source

This paper presents the detailed design and the key system performance results of a comprehensive laboratory demonstrator for a broadband Ka-band multi-beam satellite system exploiting the new DVB-S2 standard with adaptive coding and modulation (ACM). This complete demonstrator allows in-depth verification and optimization of the ACM techniques applied to large satellite broadband networks, as well as complementing and confirming the more theoretical or simulation-based findings published so far. It is demonstrated that few ACM configurations (in terms of modulation and coding) are able to efficiently cope with a typical Ka-band multi-beam satellite system with negligible capacity loss. It is also demonstrated that the exploitation of ACM thresholds with hysteresis represents the most reliable way to adapt the physical layer configuration to the spatial and time variability of the channel conditions while avoiding too many physical layer configuration changes. Simple ACM adaptation techniques, readily implementable over large-scale networks, are shown to perform very well, fulfilling the target packet-error rate requirements even in the presence of deep fading conditions. The impact of carrier phase noise and satellite nonlinearity has also been measured. Copyright © 2009 John Wiley & Sons, Ltd. Source

SafeTRIP is a project in progress partially financed by the Seventh Framework Programme's (FP7) European research and development activities in the subtheme of Sustainable Surface Transportation. SafeTRIP intends to implement a demonstrator of an integrated system, from data collection to service provision, that aims at optimising the use of road transport infrastructures. In this paper a general overview of the SafeTRIP architecture is presented. A detailed analysis and description of the functionalities characterizing the main elements of the system and a brief description of infomobility services such as alerting, disaster recovery and dynamic traffic data is given. A relevant part of this architecture is the Satellite Communication System which operates through the W2A Geostationary Satellite. To have an idea of the potentialities of the proposed system, a summary of functional requirements and performances relating to different types of services implemented is reported. © 2012 IEEE.
