The present paper addresses the importance of optimal sizing hybrid microgeneration systems for dwelling applications. Indeed, the parameters, the constraints and the criteria which must be considered in the sizing phase are several: i) energy prices, ii) ambient conditions, iii) energy demand, iv) units' characteristics, v) electricity grid constraints. The hybrid renewable system under analysis is made up of an electrical solar device and a micro-Combined Heat and Power, micro-CHP unit coupled to a cooling device. In addition to traditional PhotoVoltaic, PV, technology the work considers a High Concentration PhotoVoltaic, HCPV, device, with the aim of understanding its potential application in the countries of the Mediterranean. Results point out the importance of optimal sizing hybrid renewable energy systems, in particular the micro-CHP unit, in order to maximize the economic and the energy savings with respect to conventional generation. Furthermore results point out the critical nature of electricity grid constraints, which can halve the achievable energy savings. © 2014 Elsevier Ltd. All rights reserved. Source

Fuelling micro-combined heat and power (micro-CHP) devices using renewable sources, such as biogas, can enhance the energy and environmental benefits associated with such devices. This paper presents a solution for increasing the electric efficiency of biogas-fed Stirling co-generators by recuperating the energy content of the combustion flue gas. When economically and energetically convenient for micro-CHP operation, the exhausts can be used to pre-heat fresh combustion air. It was assessed that, due to the introduction of a spiral gas-gas heat exchanger, whose main design parameters were identified, the electric efficiency of the Stirling unit can be raised to up to 22.5%. To determine the advantages of applying the system analysed over a traditional Stirling device, a specific algorithm for the optimal management of the micro-CHP unit was built and applied to a residential case study. The results demonstrate that the extra cost of the high-efficiency recuperator can be easily recovered in approximately two years of system operation, providing an additional advantage over a standard Stirling device in terms of primary energy consumption and an approximately 6% increase in economic savings. © 2014 Elsevier Ltd.

In the alpine province of South Tyrol (500,000 inhabitants) science and innovation do not have a long tradition, but as everywhere they are crucial for the future development of the economy. LUNA (LUnga Notte della ricerca Lange NAcht der Forschung), which takes place every other year, is a great opportunity for the population to get in touch with scientists, to learn about research projects in the region and to have fun with scientific themes. The main organisers of LUNA are committed to creating a tradition for science and innovation in South Tyrol, organising different science events at planned intervals: LUNA every second year, science cafs every summer, activities for schools throughout the school year, etc. LUNA will be organised for the fourth time on 26 September in Bolzano/Bozen, the principal town of South Tyrol with 100,000 inhabitants. Once again a consortium comprising the European Academy of Bolzano/Bozen, the Free University of Bolzano /Bozen and Techno Innovation South Tyrol will be the main organisers with their headquarters used as the major venues. A further five to seven additional partners (businesses, museums and other research institutions) are expected to open their doors as well. The Night will thus transform Bolzano into an exciting science park, where children and adults will be able to have fun with science at up to ten different venues connected via a free shuttle service. An intensive Awareness Campaign will ensure that about 300,000 people will be aware of LUNA. We expect around 14,000 16,000 visitors. From 5 pm until midnight we will show our guests, how Science makes you fly which is the main theme for this years event. People will be given the opportunity to participate in many different interactive presentations, games, quizzes, experiments and science performances. They will have the chance to talk, enjoy themselves, eat, drink and even dance with experts and scientists from many different discipline

Developing the capabilities of children to comprehend written texts is key to their development as young adults. Text comprehension skills and strategies develop enormously from the age of 7-8 until the age of 11, when children develop as independent readers. Nowadays, more and more young children turn out to be poor (text) comprehenders: they demonstrate text comprehension difficulties, related to inference-making skills, despite proficiency in word decoding and other low-level cognitive skills.\n\nThough there are several pencil-and-paper reading interventions for improving inference-making skills on text, and specifically addressed to poor comprehenders, the design and development of adaptive learning systems for this purpose are lagging behind. A few adaptive learning systems consider specific inference-making interventions that are pivotal in text comprehension, but such systems are designed for high-school children or university-level students, and with textbooks as reading material. The use of more intelligent adaptive learning systems to custom-tailor such interventions in an adaptive fashion to (hearing and deaf) poor comprehenders has tremendous potential. TERENCE embodies that potential.\n\nTERENCE aims at offering innovative usability and evaluation guidelines, refining the current cognitive and pedagogical models concerning story comprehension and inference making, and delivering a showcase intelligent adaptive learning system. The systems smart games, developed and classified according to the refined models, will ask children to draw inferences about temporal events of stories, in Italian and in English. Moreover, the system will allow teachers to choose and custom-tailor the types of stories and games according to the needs of their learners.\n\nThe guidelines, the models and the system will be the result of an orchestrated cross-disciplinary effort of European experts in diverse and complementary fields (art and design, computer science, engineering, linguistics, evidence-based medicine, psychology), and with the constant involvement of the end-users (deaf and hearing poor comprehenders, their educators) from schools in Brighton (UK), and in the Veneto area (Italy).

The objective of this 4-year project is to provide the analytical basis for a socio-ecological transition in Europe: the change to a new growth path with smart, sustainable and inclusive growth as is envisaged in the EU 2020 strategy. In order to support the transition, we analyse the need, the feasibility and best practice for change, specifying the institutional changes needed at all policy levels to implement these options. The old and new challenges Europe is facing define the starting point: globalisation, new technologies and postindustrialisation, demographic change and ecology in the context of welfare systems that have come under stress due to high public deficits. The vision is that Europe will become a role model for a high road growth path which actively incorporates social and ecological goals, employment, gender and cultural aspects in an ambitious, forward looking way while continuing to be competitive in a globalised world. To achieve these objectives, the consortium will carry out and synthesise robust research in research areas covering the challenges to the welfare system, the biophysical dimension of socio-economic development, the identification of drivers towards socio-ecological transition, the role of governance and institutions on the European as well as the regional level. The consortium will benefit from ongoing dialogue with international experts in the form of expert panels and sounding boards, taking into account their views on the direction and feasibility for this new growth path. The project will be carried out by a consortium of 34 partners from universities and research institutes with international and interdisciplinary expertise. It represents 12 member states. High level Scientific and Policy Boards will monitor the analysis and the policy conclusions to guarantee the impact and dissemination of the results.
