Modern enterprise systems have to comply to regulations such as Basel III resulting in complex security requirements. These requirements need to be modeled at design-time and enforced at runtime. Moreover, modern enterprise systems are often business-process driven, i.e., the system behavior is described as high-level business processes that are executed by a business process execution engine. Consequently, there is a need for an integrated and tool-supported methodology that allows for specifying and enforcing compliance and security requirements for business process-driven enterprise systems. In this paper, we present a tool chain supporting both the design-time modeling as well as the run-time enforcement of security requirements for business process-driven systems. Copyright 2012 ACM.

This paper discusses the importance of spatial data for the development of Smart Cities. Analysing of geospatial sensor data streams and integrating them into a common urban model information leads to smart geospatial data. It constitutes a necessary condition for the city of the future, whose infrastructure is linked with information and communication-related components. Based on the projects Plus Energy Community Wüstenrot and SimStadt this development is to be exemplified. © 2015, Wissner Verlag. All rights reserved. Source

Free and open source geo-information systems which can be used as clients in a geodata infrastructure as well as for manipulating and analyzing data in a desktop environment are becoming increasingly important. This is mainly due to recent advances in several projects over the last years. In the following some interesting open source projects in this context will be introduced. A special focus is set on the possibilities of cartographic map design. Source

The CI-NERGY Marie Curie Initial Training Network (ITN) aims to train young scientists to develop urban decision making and operational optimisation software tools to minimise non-renewable energy use in cities. The training will be carried out by a close collaboration of six of the best academic research centres and four leading industrial companies from the energy and software technology sector (Siemens, WienEnergie, EDF/EIFER, and IES). The research fellows will apply their results in two case study cities (Geneva and Vienna), which were chosen for their very ambitious sustainability goals. The CI-NERGY network will be a highly multi-disciplinary coordinated PhD programme on urban energy sustainability, covering the key challenges in cities related to a low carbon future. There is a gap in high level integrated training in the urban energy research field, which is due to the wide range of fragmented disciplines from building physics and energy supply technologies with electrical and thermal engineering up to software engineering and information technology. The CI-NERGY network wide training provided by excellent academic and industry partners from all areas of smart cities will close this gap. The impact of the network training activities will be highly noticeable for energy supply utilities, IT companies, policy makers, urban planners, researchers on sustainable urban energy systems and finally the inhabitants of cities themselves. All sectors mentioned will provide excellent career opportunities for the research fellows, who will gain excellent knowledge of the sectorial requirements by a structured secondment plan.

District Heating and Cooling networks distribute energy from a centralized generation plant to a number of remote customers. As such, actual DHC systems suffer from significant heat losses highly unexplored integration potential of different available energy sources (e.g. renewables and waste heat) into the network high installation costs. FLEXYNETS will develop, demonstrate and deploy a new generation of intelligent district heating and cooling networks that reduce energy transportation losses by working at neutral temperature levels. Reversible heat pumps and chillers will be used to exchange heat with the DHC network on the demand side. In this way, the same network can provide contemporary heating and cooling. FLEXYNETS solutions will integrate effectively multiple generation sources (including high- and low-temperature solar thermal, biomass, PV, cogeneration and waste heat) where they are available along the DHC network, by managing energy at different temperature levels and assuring optimized exergy exploitation. Together with storages, control strategies that optimize the harvest of renewable energy sources are key from the technical and economic points of view. On the one hand, strategies will be assessed that assure a thermal balance among diffused heat generation, storage and utilization. On the other, policies will be elaborated to decide when energy is to be gathered locally or exchanged (both purchased and sold) with the electricity and gas networks. The optimal management of such new generation networks will lead to a synergic effect on primary energy savings (hence on the reduction of the CO2 emissions), assuring at the same time investment and operation profitability. As such, FLEXYNETS will contribute to a higher penetration of smart DHC networks on the heating and cooling market, and will contribute to the European recovery plan.
