    Abstract The heavy clay industry brick is in many countries a very important economic factor with far reaching financial and environmental impacts. In the industrialized countries the use of alternative fuels in the heavy clay industry is rather limited.The European brick industries common current research activity is mainly focused on synthgas from waste streams. In-house research activity by single brick companies does, at least in Europe, not take place at the moment. The situation in the developing and industrializing countries is far different: The use of alternative,fossil and renewable, fuels in these countries is still wide spread. The use of such fuels does sometimes have severe negative impacts on the environment. This paper gives an overview of the use of various renewable and alternative fuels in the heavy clay industry in several countries and the environmental and financial impacts these fuels have or might have on the operation of a typical installation in various parts of the world (Maghreb, Europe, USA, Australia,India, Vietnam). Two examples in which alternative fuels have been or are used, one in an industrializing and one in an industrialized country, are briefly presented. A comparative product life cycle analysis, LCA, is presented

    Towards 5G Software-Defined Ecosystems: Technical Challenges, Business Sustainability and Policy Issues

    Techno-economic drivers are creating the conditions for a radical change of paradigm in the design and operation of future telecommunications infrastructures. In fact, SDN, NFV, Cloud and Edge-Fog Computing are converging together into a single systemic transformation termed “Softwarization” that will find concrete exploitations in 5G systems. The IEEE SDN Initiative1 has elaborated a vision, an evolutionary path and some techno-economic scenarios of this transformation: specifically, the major technical challenges, business sustainability and policy issues have been investigated. This white paper presents: 1) an overview on the main techno-economic drivers steering the “Softwarization” of telecommunications; 2) an introduction to the Open Mobile Edge Cloud vision (covered in a companion white paper); 3) the main technical challenges in terms of operations, security and policy; 4) an analysis of the potential role of open source software; 5) some use case proposals for proof-of-concepts; and 6) a short description of the main socio-economic impacts being produced by “Softwarization”. Along these directions, IEEE SDN is also developing of an open catalogue of software platforms, toolkits, and functionalities aiming at a step-by-step development and aggregation of test-beds/field-trials on SDNNFV- 5G

    Software-Defined Networks for Future Networks and Services: Main Technical Challenges and Business Implications

    In 2013, the IEEE Future Directions Committee (FDC) formed an SDN work group to explore the amount of interest in forming an IEEE Software-Defined Network (SDN) Community. To this end, a Workshop on "SDN for Future Networks and Services" (SDN4FNS'13) was organized in Trento, Italy (Nov. 11th-13th 2013). Following the results of the workshop, in this paper, we have further analyzed scenarios, prior-art, state of standardization, and further discussed the main technical challenges and socio-economic aspects of SDN and virtualization in future networks and services. A number of research and development directions have been identified in this white paper, along with a comprehensive analysis of the technical feasibility and business availability of those fundamental technologies. A radical industry transition towards the "economy of information through softwarization" is expected in the near future

    The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-642-01524-3_8This chapter summarises the activities on optical packet switching (OPS) and optical burst switching (OBS) carried out by the COST 291 partners in the last 4 years. It consists of an introduction, five sections with contributions on five different specific topics, and a final section dedicated to the conclusions. Each section contains an introductive state-of-the-art description of the specific topic and at least one contribution on that topic. The conclusions give some points on the current situation of the OPS/OBS paradigms
