In Fragebogen-Untersuchungen zur Lärmwirkung wurden bisher sehr unterschiedliche Operationalisierungen von Wirkungsvariablen (wie z.B. Belästigung, Störung von Aktivitäten) und außer-akustischen Faktoren (sog. Moderatoren wie z.B. Lärmempfindlichkeit, misfeasance) verwendet. Deshalb hat sich die Arbeitsgruppe community response der International Commission on the Biological Effects of Noise (ICBEN, Team No. 6) als langfristiges Ziel die Entwicklung von Fragebogen-Guidelines und die Formulierung eines Muster-Fragebogens für die Lärmwirkungsforschung gesetzt. D.h. es soll ein Vorschlag erarbeitet werden, in welcher Form globale und spezifische Lärmwirkungen in Befragungen erhoben werden sollten. Um dieses Vorhaben zu unterstützen, hat der Arbeitskreis Ökologische Lärmforschung die Erstellung einer systematischen Übersicht über vorhandene Fragebögen aus Lärmwirkungsstudien auf internationaler Ebene in Angriff genommen. Diese Übersicht soll es u.a. ermöglichen, die Struktur von verschiedenen Fragebögen sowie die in ihnen verwendeten Operationalisierungen für Lärmwirkungs- und Moderatorvariablen (hinsichtlich Art der Frageformulierung sowie der Antwortformate) zu vergleichen. Für den/die einzelne/n Lärmforscher/in bietet diese Übersicht die Möglichkeit, sich auf sehr effiziente Art und Weise darüber zu informieren, wie bestimmte Konstrukte in bisherigen Untersuchungen operationalisiert worden sind bzw. welche Alternativen zu den bereits selbst angewandten Operationalisierungen bestehen. Nach einer systematischen Ermittlung von Namen und Adressen einschlägiger Lärmforscher/innen, wurden diese um die Zusendung von Fragebögen sowie ergänzender Materialien aus eigenen Lärmwirkungsstudien gebeten. Die zugesandten Fragebögen werden gegebenenfalls übersetzt und mit der Methode der qualitativen Inhaltsanalyse ausgewertet. Hierbei werden die Fragebögen im Hinblick auf formelle Aspekte (z.B. Jahr der Erhebung, Sprache, Art der Befragungsmethode) wie auch im Hinblick auf strukturelle Aspekte (z.B. Umfang des Fragebogens, abgefragte Variablengruppen, Antwortformate) ausgewertet. Hauptgegenstand der Auswertung ist aber insbesondere die Auswertung der Lärmwirkungsvariablen (z.B. die Abfrage der globalen Lärmbelästigung, Aktivitätenstörungen, Kommunikationsstörungen) sowie der Moderatorvariablen (z.B. Lärmempfindlichkeit, Lärmbewältigungsvermögen, misfeasance). Parallel dazu wurde eine Datenbank entwickelt, in der die Ergebnisse der Analysen dargestellt und verwaltet werden. Diese Datenbank wird ab November 2001 im Internet unter http://www.eco.psy.ruhr-uni-bochum.de/nqd für jede/n interessierte/n Forscher/in zugänglich und nutzbar sein. Langfristig ist darüber hinaus geplant, ein Archiv mit den Original-Fragebögen aufzubauen, in dem einzelne Fragebögen auf Wunsch eingesehen werden können.

Objective: Based on the successful implementation of multi-user solar hybrid grids (MSG) in Europe, this project deals with the design of rural village electrification technology and schemes for rural communities, schools, or dispensaries in Mediterranean partner cou ntries. For this purpose, this project further develops and adapts an integrated approach, covering all aspects required (social, economical, financial and technical) for long term sustainable energy service achieved with hybrid systems. This approach is e laborated in a common effort between partners in the EU and Mediterranean partner countries). There is an initial preparation phase addressing research on technological, socio-economic and institutional issues in each target country covered by this project (Morocco, Algeria, Jordan, Lebanon), which are all crucial for successful implementation. The systems to be developed are adapted to the context in Mediterranean partner countries, such as high robustness, and additional communications for remote monitori ng. They are based on a locally appropriate energy mix based on PV plus wind or micro-hydraulic, and fuel, feeding local micro grids. Intelligent energy distribution devices assure reliable energy service for each user so that a high level of energy effici ency and demand side management is achieved during the operation of the systems. The project previews dissemination of results using a rural electrification manual, local dissemination actions in each target country, one training seminar and one internatio nal conference targeting at specialists from all Mediterranean partner countries.
The research, development and demonstration activities planned for the ERG project focus on the solar energy supply chain, starting form solar cells and proceeding along with innovative energy extraction (harvesting) techniques, high efficiency power conversion and finally managing the energy distribution inside a smart grid, with the target of different classes of applications, from house to small area, as well as application specific 'local grid' (healthcare, automotive, etc). By considering the full solar energy supply chain, we expect to produce relevant improvements of the industrial state-of-the-art in the efficiency of solar cells, in the optimization of energy generated by photovoltaic systems, in the loss reduction of power converters and, finally, in energy management strategy. At the initial chain-link of the energy value chain, the project aims to design and develop a set of innovative solar cells. In particular we primarily target the development of ultra-thin (20 micron) Si wafer PV cells, Si hetero-junction cells (tandem/multi-junction and hetero-junction contacts), novel architectures (e.g., back-contact), novel materials (for Si hetero-junctions, ARC, and passivation dielectrics), novel approaches for screen printing and laser processing, with focus to the case of back-contact cells. As a promising low-cost alternative to Si, ERG will pursue the goal of totally printable dye-sensitized-solar-cells (DSSC). This will include (a) printable electrolyte (to replace liquid electrolyte), (b) advanced TiO2 electrode, and (c) counter electrode (to meet high performance DSSC applications). The overall objective is to demonstrate DSSC products for commercial applications. The next downward chain-link addressed by the project deals with optimization of the energy generated by photovoltaic systems by focusing on power management electronics for silicon cell panels and on micro electromechanical systems for Concentrated Photovoltaic cells (CPV). The complete supply chains will be considered for optimum energy exploitation by Maximum Power Point Tracking (MPPT) and power conversion on module / segment levels for PV and also CPV solar generators. The architecture study will elaborate different profiles of end-users, including direct grid connection, energy storage option and E-mobility support. As the final chain-link is concerned, the project will develop behavioural models for the individual components of the 'Smart Grid'. This allows the development of optimal energy dispatching and battery charging algorithms. These algorithms will obtain their input from sensors distributed over the network, with typically, but not exclusive, a wireless communication infrastructure. A full set of demonstrators, including innovative PV cells, novel conversion systems for PV and CPV inverters, and network demonstrators based on a household application and an industrial application will complete the project deliverables.
This proposal is a continuation of the project 'GeoKernels': Kernel-Based Methods for Geo- and Environmental Sciences (200021-113944/1). The projects deal with the fundamental developments in the field of intelligent geospatial data analysis and modelling using Machine Learning algorithms. The first phase of the GeoKernels project provided a general methodology for using the state-of-the-art models in machine learning (where kernel methods establish one of the main successful areas) for spatio-temporal data analysis and modelling. Real life data lie on some lower-dimensional manifolds in the original high-dimensional geo-feature space. For environmental data these natural low-dimensional geo-manifolds are induced by rivers, relief features, urban structures, hydro-geological formations, etc. During PhaseI in the GeoKernels methodology, semi-supervised learning was applied to the stated problems in an efficient and elegant manner. The continuation of the project (Phase2) is aimed at advancing the data-driven GeoKernels modelling methodology, bringing it closer to the need of real-life operational use, from one side, and developing new methods concerned with geomanifold modelling by feature extraction and interpretable predictions with multiple kernel learning. The new developments will provide more transparency to the data-driven methods and will bring more flexibility for modelling complex environmental processes. The methods are particularly targeted at applications in natural hazards assessments and forecasting, topo-climatic modelling and renewable resources evaluation. Due to the established collaboration, the results of this multidisciplinary project will improve spatial data collection and management process in different scientific fields, will develop new procedures of environmental pattern recognition and modelling approaches using recent achievements in machine learning. The main results will be presented at the international conferences and workshops and published in scientific journals and books. The results, including the software modules (Machine Learning Office) and online interactive case studies will be available at the website of the project for the research and educational purposes (www.geokernels.org).
The overall goal of the GEOMON project is to sustain and analyze European ground-based observations of atmospheric composition, complementary with satellite measurements, in order to quantify and understand the ongoing changes. GEOMON is a first step to build a future integrated pan-European Atmospheric Observing System dealing with systematic observations of long-lived greenhouse gases, reactive gases, aerosols, and stratospheric ozone. This will lay the foundations for a European contribution to GEOSS and optimize the European strategy of environmental monitoring in the field of atmospheric composition observations. Specifically, we will unify and harmonize the main Europeans networks of surface and aircraft-based measurements of atmospheric composition parameters and integrate these measurements with those of satellites. The access to data and data-products will be coordinated at a common data centre for more efficient use. GEOMon will support data gathering at existing networks if necessary, rescue and compile existing ground-based data, and develop new methodologies to use these data for satellite validation and interpretation.. In addition, GEOMON will enable innovative ground-based measurements complementary to satellites, made by upward looking ground based remote sensing instruments Max-DOAS, FTIR, and LIDAR and by systematic measurement programmes of upper-tropospheric composition using passenger aircrafts CARIBIC and MOZAIC. These data will serve to reduce biases and random errors in satellite observations and facilitate interpretation of the columnar measurements in combination with surface data. This will result in a significant improvement in the use of existing and future satellite data. Common techniques and modelling tools will be used in order to add value to the GEOMON data observations, to facilitate their use in satellite validation and help design an optimal network.

This request R'Equip is within the context of a research project dealing with an experimental investigation of unsaturated soils behavior under very high temperature, suction, and pressure loadings. The aims of this research program require the development of a new specific apparatus adapted to these extreme testing conditions for LMS-EPFL. Defining the thermo-hydro-mechanical behavior of materials is one of the main modern issues in soil mechanics. In recent years, thermal-geomechanical problems have strongly increased as a result of the demand for new and enlarged types of applications such as high-level nuclear waste disposal, energy extraction from pressurized geothermal reservoirs, heat storage, zones around buried high-voltage cables, geothermal structures, and so on. For sure, one of the fundamental challenges in this field is an insight in the understanding of unsaturated soil behavior at high pressures and temperatures for host rocks and buffer materials for radioactive waste. Several of the leading research teams around the world have now implemented research programs in this area. The aim of the proposed research is therefore the development of a new multi-purpose triaxial cell able to perform tests on unsaturated materials for wide ranges of temperature (20-150 C) and cell pressure (up to 30 MPa) along with suction control. The LMS-EPFL is already involved in two important research projects in the field of the safety study of disposal for vitrified High Level Wastes. The TIMODAZ (Thermal Impact on the Damaged Zone around a Radioactive Waste Disposal in Clay Host Rocks) European project investigates the behavior of two host rocks (Boom Clay from Mol (Belgium) and Opalinus Clay from Mont Terri (Switzerland)) for high level waste repository and a collaboration with the NAGRA (National Cooperative for the Disposal of Radioactive Waste - Switzerland) characterizes the thermo-hydro-mechanical behavior of granular bentonite as a buffer material. To conduct these experimental programs in the best way, the laboratories need to acquire such a triaxial cell adapted for very high thermo-hydro-mechanical loadings. The decisiveness of these experimental programs is to use the test results to define for each material the parameters of ACMEG-TS (Advanced Constitutive Model for Environmental Geomechanics) model developed by the LMS, which takes into account at the same time the temperature and the suction effects on soil behavior. This model will permit to predict the evolution of the clay host rocks or the granular bentonite in order to take into account all the thermo-hydro-mechanical processes in the safety study of disposal for vitrified High Level Wastes.
MAI-TAI deals with integrated water resources management. It is designed as a coordination action of leading research and innovation operators, aiming at developing a coherent set of innovative, relevant and cooperative policy options and management strategies. Regionally it works with partners from China and India, and the work will focus around two lead river basins: The Hai river basin in North-East China and the Yamuna river basin in North India, both in arid and/or semi arid regions. The proposal features the following core coordination activities: 1. Enabling a dialogue between researchers and practitioners promoting state of the art and indigenous technologies and practices: The consortium believes that modern systems alone are not capable of solving the water needs of the people in many developing countries, and there is a strong need of generating innovative options through cross fertilization between both worlds. This cross-fertilization will be enabled by methods and rich experiences of user innovations research. 2. Based on (1), innovative policy options and management strategies will be compiled. Then, a multi-stakeholder interaction in order to evaluate these options and strategies will be carried out, supported by intelligent knowledge management tools: In the presence of a variety of actors (institutions, organisations, individuals) each with specific forms of knowledge with respect to scale, topic, reasoning processes, and a large number of information expected to be generated through the multi-stakeholder interaction, the issue of learning and knowledge management is of paramount importance. A strong impact of the coordination action is ensured by a highly inter- and transdisciplinary team, encompassing internationally reputable scientific institutions as well as strong governmental partners and NGOs. The latter two will considerable facilitate a wide and in particular meaningful stakeholder dialogue throughout the project.
