These measurements confirm our assumption (based on thermal expansion and elastic measurements) that (C60)x(C70)1-x alloys form orientational glass for 0.1<x<0.3. Furthermore, we were able to isolate several small single crystals of C60/C70, and analyze them using the rotating

The paper incorporates the best aspects of the state-of-the-art in environmental informatics with geospatial solutions and scalable processing capabilities of Internet-based tools. It specifically targets the promotion of the "Environmental Observation Web" as an observation-centric paradigm for building the next generation of environmental applications. In the Environmental Observation Web, the great majority of data are considered as observations. These can be generated from sensors (hardware), numerical simulations (models), as well as by humans (human sensors). Independently from the observation provenance and application scope, data can be represented and processed in a standardised way in order to understand environmental processes and their interdependencies. The development of cross-domain applications is then leveraged by technologies such as Cloud Computing, Internet of Things, Big Data Processing and Analytics. For example, "the cloud" can satisfy the peak-performance needs of applications which may occasionally use large amounts of processing power at a fraction of the price of a dedicated server farm. The paper also addresses the need for Specific Enablers that connect mainstream Future Internet capabilities with sensor and geospatial technologies. Main categories of such Specific Enablers are described with an overall architectural approach for developing environmental applications and exemplar use cases.

As an important factor for the maintenance of the current quality standard of Austria’s protection and emergency system, the further engagement of voluntariness has to be ensured and enhanced in the light of the ongoing societal change. On the one hand, the involvement of new media provides opportunities to expand the organizations’ service portfolio to create a broader participation for citizens’ engagement; on the other hand, long lasting and formal memberships are often a challenge for the current dynamic lifestyle. To face this situation, the involvement of new media services for volunteer management in order to enable new modes of voluntary binding is a promising strategically effort. A new process called “crowdtasking” dedicated to the improvement of volunteer management applying new media is discussed; new processes of volunteer management are presented by exemplary initiatives of humanitarian non-governmental organizations, such as the Austrian Red Cross.

Proposed solution is based on the Open Geospatial Consortium standards, and follows the ideas expressed in SANY Sensor Service Architecture (SensorSA). SUDPLAN also continued the development of the SANY software, resulting in native SOS, SPS and 2D coverage support in "Time Series Toolbox" framework for building sensor web applications. SUD-PLAN re-uses much of the OGC SWE and SANY SensorSA functionality to: (1) configure and run the models; (2) provide the data (observations) required for model execution; (3) inform the user on model run progress and (4) access the model results. In this paper, we shall describe the SUDPLAN's experiences with implementing of the interoperable Model Web using OGC standards, and discuss the advantages of various services from the OGC SWE suite as compared to non-SWE alternatives in the Climate Change context.

The resulting "Sensor Service Architecture v1" specification is available on SANY-IP web site. As part of this activity, Austrian Research Centres (ARC) developed a first prototype of the "SensorSA Data Acquisition System" (SensorSA DAS) and cascading Sensor Observation Service (SOS-X).

Consequently, only a tiny fraction of the web can be easily used as a semantic "database" today. Drupal 7 changes the rules of the game by integrating the functionality required for structuring and semantically annotating arbitrary content types in the Drupal "core", as well as encouraging the module authors to use this functionality in their Drupal extensions. This paper presents the authors recent experiences with strengths and shortcomings of the Drupal 6 and Drupal 7 semantic web extensions, and discusses feasibility of the future semantic web environmental applications based on a Drupal platform. The intention of the paper is (1) to analyse the state of the art in semantic web support, as well as the potentials for further development in Drupal today; (2) to prove the feasibility of Drupal based semantic web applications for environmental usage area; and (3) to introduce the idea of Drupal as a rapid prototyping development environment.

FI-PPP has an ambitious goal of developing a set of Generic FI Enablers (GEs) - software and hardware tools that mwill simplify development of thematic future internet applications. Our role in the programme was to provide requirements and assess the usability of the GEs from the point of view of the environmental usage area. In addition, we specified and developed three proof of concept implementations of environmental FI applications, and a set of specific environmental enablers (SEs) complementing the functionality offered by GEs. Rather than trying to rebuild the whole infrastructure of the Environmental Information Space (EIS), we concentrated on two aspects: (1) how to assure the existing and future EIS services and applications ca...

The formal mathematical language utilized is the stochastic Marked Poisson Process. The point of departure is the theory on Recognition-primed Decisions. This paper is written for researchers interested in the formal presentation of situational awareness for simulation applications related to emergency/rescue management training where experienced commanders generate response scenarios for comparison and teaching of non-experienced decision-makers. Paper also briefly discusses the possibility of using such formal model as a point of departure in the development of agent-based models and simulations.

Two types of volunteers are deployed to discover and report some "issues". The first type walks randomly and reports and reports nearby issues. Second type can be tasked to confirm existing reports. The model clearly shows that a small number of taskable volunteers greatly shortens the time needed to confirm the findings.
