    Despite its potential gaze interaction is still not a widely-used interaction concept. Major drawbacks as the calibration, strain of the eyes and the high number of false alarms are associated with gaze based interaction and limit its practicability for every-day human computer interaction. In this paper two experiments are described which use smooth pursuit eye movements on moving display buttons. The first experiment was conducted to extract an easy and fast interaction concept and at the same time to collect data to develop a specific but robust algorithm. In a follow-up experiment, twelve conventionally calibrated participants interacted successfully with the system. For another group of twelve people the eye tracker was not calibrated individually, but on a third person. Results show that for both groups interaction was possible without false alarms. Both groups rated the user experience of the system as positive

    Organised by: Cranfield UniversityThe use models of Industrial Product-Service Systems are based on the idea of offering functionality, availability or results. This paper proposes a concept for multimodal user support in interaction with condition monitoring and knowledge generation, whilst taking knowledge protection into consideration. A shared-vision system connects a less-qualified person with an expert for solving problems collaboratively. The user is instructed via multimodal user interfaces, which require data related to the service design, construction model as well as the current machine condition. Such data is acquired by a process accompanying information system, which deliver information relevant to the required service from sensors.Mori Seiki – The Machine Tool Company; BAE Systems; S4T – Support Service Solutions: Strategy and Transitio

    Titelblatt, Inhaltsverzeichnis, Lebenslauf, Literatur, Material und Methoden, Ergebnisse, Zusammenfassung, Summary, LiteraturverzeichnisIn dieser Studie wird die Möglichkeit der Behandlung von Pferden mit manueller Lymphdrainage untersucht. In die Studie einbezogen wurden Pferde mit chronischer Phlegmone einer Gliedmaße. Alle Tiere zeigten bei vorherigen Therapieversuchen keine Verbesserung des Zustandes. Ergebnisse wurden mit Hilfe von Photographien und Volumenberechungen der betroffenen Gliedmaße dokumentiert. Der Zustand bei drei Pferden wurde mit Hilfe der indirekten Lymphographie weiter charakterisiert. Alle Pferde zeigten eine deutliche Verbesserung des Zustandes nach der Therapie. Klinische und lymphographische Befunde weisen darauf hin, daß das Krankheitsbild der "chronischen Phlegmone" besser als chronisches Lymphödem zu bezeichnen wäre.The possibilities and modalities of treating horses with manual lymphatic drainage are investigated. Object of this study are horses with chronic cellulitis of a leg. All horses had been resistant to prior therapies. All patients were treated with manual lymphatic drainage on a daily bases. Results were documented with photography and volume calculation of the affected legs. The condition in three horses was further characterized with the help of indirect lymphography. As a result all horses showed a marked improvement of the condition. Clinical and lymphographic findings suggest that the condition known as "chronic cellulitis" would better be described as chronic lymphedema

Such fibrils can be produced by processing a coarse mixture of LCP and polyethyleneterephthalate (PET) powders in an extrusion apparatus in which preferentially elongational, but only weak shear flows occur. The rheological conditions for the success of this process are explained

    Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG geförderten) Allianz- bzw. Nationallizenz frei zugänglich.This publication is with permission of the rights owner freely accessible due to an Alliance licence and a national licence (funded by the DFG, German Research Foundation) respectively.A new technique for blending liquid crystalline polymers (LCPs) with thermoplastic polymers is described. With poly(ethylene terephthalate) as the matrix and Vectra B950 as the LCP, fibers containing quasi-continuous LCP-fibrils can be produced even when the LCP-concentration is very low (1 wt.-% LCP or less). Fragmentation tests show excellent bonding between the components. The elastic modulus of the LCP-containing fibers is significantly increased

    Hydrogeochemical characterization and monitoring at the Hontomin site (Spain) for geological storage of CO2

    EGU General Assembly 2011, 3-8 Abril 2011, Viena (Austria)This abstract describes the monitoring equipment and characterization tests planned at the Hontomin site, Northern Spain, where the Energy City Foundation (CIUDEN) of the Spanish Government CO2 Geological Storage Programme is installing a technological demonstration plant for geological CO2 storage. The Hontomin storage structure is located in formations of lower Jurassic age: marls as the upper seal, calcites and dolomites as the storage formation, and anhydrites as lower seal. The borehole setup at Hontomin will consist of three wells: One injection well, one geophysical monitoring well, and one multilevel fluid monitoring well, in a triangular setting. The geophysical monitoring well will be located 100 m from the injection well, and the multilevel fluid monitoring well 40 m from the injection well. The injection well will be equipped with ERT electrodes, a fiber optic Distributed Temperature Sensing (DTS) system with a heating element, extensometers, and fluid pressure sensors. The geophysical monitoring well will be equipped with the same sensors plus an array of geophones. The multilevel fluid sampling well will be equipped with sampling ports for multiphase fluid sampling, a DTS with heating element, extensometers and fluid pressure sensors. The DTS will be used to measure temperature profiles, and, in combination with the heating element, to determine changes in heat conductivity and heat capacity induced by CO2 injection. The extensometers will measure deformation of the storage and seal formations. Hydrogeochemical characterization will comprise the following tests: • Several injection and pumping tests using water and acid in combination with conservative and reactive tracers in order to measure the transport parameters and chemical properties of the porous medium. • Injection and recovery of supercritical CO2 in combination with conservative and reactive gaseous tracers, in order to study the trapping mechanisms for CO2. After the characterization phase, up to 100.000 tons of supercritical CO2 will be injected into the storage formation. Continuous and intermittent injection regimes will be applied to optimize injectivity and CO2 dissolution in the brine. Before, during and after these tests, fluid sampling, pressure and deformation measurements, geophysical logs, ERT and passive and active seismic monitoring will determine how the storage and sealing formations react to the stimulations. Drilling of the wells will start in mid-2011, and hydrogeochemical characterization will start in early 2012. The experiments are funded by the Spanish Government through the CUIDEN foundation, and by the European Commission through the FP7 project MUSTANG ("A multiple space and time scale approach for the quantification of deep saline formations for CO2 storage"; contract number 227286).Peer reviewe
