More and more the continuum of care is replacing the traditional way of treating the subjects of care putting people in the centre of the healthcare process. Currently clinicians start treatment after a problem occurs due to the low adoption of Clinical Decision Support Systems (CDSS) integrated with standardised Electronic Health Record (EHR) systems; The volume to value revolution in the healthcare (from stakeholder-centric to patient-centric) will allow doctors to follow the evolution of the individual before a medical episode happens, treating the patient based on statistical trends to forecast the future. The CDSS techniques applied on telemonitoring tools permit the doctors to predict forthcoming events, improve the diagnosis and avoid continuous visits to the hospital, therefore saving costs. Advanced Medical Expert Support Tool is a step towards achieving the patient-centric approach by incorporating the health information into the EHR using European standards (ISO/EN 13606) to provide semantic interoperability by means of the dual model approach (reference model and archetypes). Three different CDSS modules have been implemented and contextualised publications are provided to the cardiologist to facilitate their daily work. A person-centric Graphical User Interface (GUI) facilitates the visualization of the health status of the patients providing meaningful information to the cardiologists. The use of archetypes allows scalability, transparency and efficiency to the hospital environment. © Springer International Publishing Switzerland 2014.

Home > Press > Nanobiosensors and photofunctional materials designed at ICN2 recognized by the PIONER Awards Abstract: The ceremony of the second edition of the PIONER Awards has been held today at the headquarters of the CERCA Institution in Barcelona. Five young people who have developed a doctoral thesis with industrial potential have awarded. Two of the awarded researchers developed their thesis in the Catalan Institute of Nanoscience and Nanotechnology (ICN2). Developing a doctoral thesis is one of the first major challenges of the research career. In these early stages it is very important that researchers are aware that their results may have not only a great scientific value, but also commercial and industrial implications. For this reason, promoted by the Research Centers of Catalonia (CERCA), the CERCA Institution promotes the PIONER Awards in order to distinguish those researchers who have developed a doctoral thesis with a clear commercial potential. The ceremony of the second edition of the PIONER Awards was held today at the headquarters of the CERCA Institution (Via Laietana, 2; Barcelona). Five young people who have developed their doctoral thesis within a CERCA center received the award for having initiated or strengthened a technology or product with industrial interest. Two of these awards have recognized the work of doctors who developed their doctoral thesis in the Catalan Institute of Nanoscience and Nanotechnology (ICN2). The first awarded ICN2 doctoral thesis focuses on the development of optical biosensors for diagnosis and therapeutic monitoring of various diseases, such as allergy, celiac disease or cancer. The author of the thesis, entitled "Nanoplasmonic Biosensors for Clinical Diagnosis at the Point of Care" is Dr Maria Aznar Soler, who worked under the direction of Dr M. Carmen Estevez and CSIC researcher Prof Laura M . Lechuga, Group Leader of the ICN2 NanoBioSensors and Bioanalytical Applications (NanoB2A) Group. The second ICN2 thesis applies encapsulation technologies to design intelligent materials with photochromic and thermochromic properties. It is entitled "Encapsulation of stimuli-responsive molecules for the preparation of photofunctional materials" and has been written by Dr. Nuria Vazquez, under the direction of CSIC researcher Prof Daniel Ruiz, Group Leader of the ICN2 Nanostructured Functional Materials (NanosFun), and Prof. Jordi Hernando, from the Chemistry Department at the Autonomous University of Barcelona (UAB). The rest of the winners are Dr Michal Drozdzal, from the Computer Vision Centre (CVC); Dr Alessandro Franci, from the International Center for Numerical Methods in Engineering (CIMNE); and Dr Benjamí Oller Salvia, from the Institute for Research in Biomedicine (IRB Barcelona). The fact that two of five awards have been awarded to researches developed at ICN2 evidences the commercial potential of the work developed at this center.

Proceedings of the International Conference on Radioactive Waste Management and Environmental Remediation, ICEM | Year: 2011
The evolution of the engineered barrier system (EBS) of geological repositories for radioactive waste has been the subject of many research programmes during the last decade. The emphasis of the research activities was on the elaboration of a detailed understanding of the complex thermo-hydromechanical-chemical processes, which are expected to evolve in the early post closure period in the near field. It is important to understand the coupled THM-C processes and their evolution occurring in the EBS during the early post-closure phase so it can be confirmed that the safety functions will be fulfilled. Especially, it needs to be ensured that interactions during the resaturation phase (heat pulse, gas generation, non-uniform water uptake from the host rock) do not affect the performance of the EBS in terms of its safety-relevant parameters (e.g. swelling pressure, hydraulic conductivity, diffusivity). The 7th Framework PEBS project (Long Term Performance of Engineered Barrier Systems) aims at providing in depth process understanding for constraining the conceptual and parametric uncertainties in the context of long-term safety assessment. As part of the PEBS project a series of laboratory and URL experiments are envisaged to describe the EBS behaviour after repository closure when resaturation is taking place. In this paper the very early post-closure period is targeted when the EBS is subjected to high temperatures and unsaturated conditions with a low but increasing moisture content. So far the detailed thermo-hydraulic behaviour of a bentonite EBS in a clay host rock has not been evaluated at a large scale in response to temperatures of up to 140°C at the canister surface, produced by HLW (and spent fuel), as anticipated in some of the designs considered. Furthermore, earlier THM experiments have shown that upscaling of thermal conductivity and its dependency on water content and/or humidity from the laboratory scale to a field scale needs further attention. This early post-closure thermal behaviour will be elucidated by the HE-E experiment, a 1:2 scale heating experiment setup at the Mont Terri rock laboratory, that started in June 2011. It will characterise in detail the thermal conductivity at a large scale in both pure bentonite as well as a bentonite-sand mixture, and in the Opalinus Clay host rock. The HE-E experiment is especially designed as a model validation experiment at the large scale and a modelling programme was launched in parallel to the different experimental steps. Scoping calculations were run to help the experimental design and prediction exercises taking the final design into account are foreseen. Calibration and prediction/validation will follow making use of the obtained THM dataset. This benchmarking of THM process models and codes should enhance confidence in the predictive capability of the recently developed numerical tools. It is the ultimate aim to be able to extrapolate the key parameters that might influence the fulfilment of the safety functions defined for the long term steady state. Copyright © 2011 by ASME.

The evolution of the clay-based engineered barrier system (EBS) of geological repositories for radioactive waste has been the subject of many research programmes during the last decade. The early post-closure thermal behaviour is elucidated by the HE-E experiment, a 1:2 scale heating experiment (at the Mont Terri Rock Laboratory), which was implemented in the first semester of 2011, with the initiation of the heating phase in June 2011. A maximum temperature of 140 °C was reached in June 2012. After 15 months of heating, the temperature evolution in the EBS and the Opalinus Clay reflects the design calculations, and thermally induced porewater overpressures are being measured at a few metres' distance in the Opalinus Clay. Seismic methods proved to be a sensitive tool for the continuous characterization of changes of EBS and Opalinus Clay properties. Design modelling and predictive modelling based on the as-built parameter dataset with established coupled codes (TOUGH, CODE_BRIGHT; using various geometries) are described. The results indicate that the models are generally in agreement with the observations and capable of capturing the evolution of the experiment. © The Geological Society of London 2014.

Magnetorheological (MR) dampers have received special attention as semi-active devices for mitigation of structural vibrations. Because of the inherent nonlinearity of these devices, it is difficult to obtain a reasonable mathematical inverse model. This paper is concerned with two related concepts. On one hand, it presents a new inverse model of MR dampers based on the normalized Bouc-Wen model. On the other hand, it considers a hybrid seismic control system for building structures, which combines a class of passive nonlinear base isolator with a semi-active control system. In this application, the MR damper is used as a semi-active device in which the voltage is updated by a feedback control loop. The management of MR dampers is performed in a hierarchical way according to the desired control force, the actual force of the dampers and its capacity to react. The control is applied to a numerical three-dimensional benchmark problem which is used by the structural control community as a state-of-the-art model for numerical experiments of seismic control attenuation. The performance indices show that the proposed semi-active controller behaves satisfactorily. © 2010 Elsevier Ltd. All rights reserved.

Particle-Based Methods II - Fundamentals and Applications | Year: 2011
The Particle Finite Element Method was originally developed for applications involving incompressible fluids containing free surfaces. The PFEM's fundamental features include a) updated Lagrangian description b) nodal storage of variables, c) remeshing, d) alpha-shape based free surface determination. Several fluid formulations sharing these basic ideas of the PFEM  have been developed over the past decade. One can classify the existing PFEM fluid formulations into 2 main groups: purely incompressible and quasi-incompressible ones. It was found that the quasi-incompressible formulations led to a number of advantages when applied to FSI problems involving flexible structures. However, in these latter formulations, the desired incompressible solution was only approximated and numerical difficulties when approaching the incompressibility limit (i.e. using very large values of the compressibility constant) were faced. In the present work we introduce the PFEM formulation of the new generation: it combines the best features of the previously developed methods and leads to incompressible solution, while preserving some features of the quasi-incompressible formulations advantageous for the FSI.
