Abstract
This paper presents the Adaptive Decision Support for Electricity Markets Negotiations (AiD-EM) system. AiD-EM is a multi-agent system that provides decision support to market players by incorporating multiple sub-(agent-based) systems, directed to the decision support of specific problems. These sub-systems make use of different artificial intelligence methodologies, such as machine learning and evolutionary computing, to enable players adaptation in the planning phase and in actual negotiations in auction-based markets and bilateral negotiations. AiD-EM demonstration is enabled by its connection to MASCEM (Multi-Agent Simulator of Competitive Electricity Markets).

Abstract
Social media are privileged vehicles to generate rich data created with unprecedented multi-faceted insights to drive faster ideation and commercialisation of client-centric innovations. The essence of data generated through social media is rooted in the connections and relationships it enables between firms and their stakeholders, and represents one of the greatest assets for data-driven innovation. As most of the firms are still experiencing and trailblazing in this matter, the current challenge is therefore to learn how to benefit from social media's potential for innovation purposes. In the last decade, research interest has increased towards understanding social media – innovation interactions. The reliance on the wisdom of the crowd in driving major business decisions and shaping society's way of life is now well acknowledged in academic and business literature. Social media is increasingly used as a tool to manage knowledge flows within and across organisation boundaries in the process of innovation. Yet, conceptualisation of social media and innovation interaction and a systematic review of how far the field has come remains providential. Therefore, through a systematic literature review we aim to identify research trends and gaps in the field, conceptualise current paradigmatic views and therein provide clear propositions to guide future research. Based on a systematic review, 111 articles published in peer-reviewed journals and found in EBSCO Host® and Scopus® databases are descriptively analysed, with results synthesized across current research trends. Findings suggest social media is seen as enabler and driver of innovation, with behavioural and resource based perspectives being the most popular theoretical lens used by researchers. The originality of the paper is rooted in the comprehensive search and systematic review of studies in the discourse, which have not been unified to date. Implications for advancement of knowledge are embedded in the purposefully proposed theoretical, contextual and methodological perspectives, providing future research directions for exploring social media capability in innovation management.

Abstract
This paper considers the problem of scheduling jobs in a permutation flow shop with the objective of minimizing total earliness and tardiness. Unforced idle time is considered in order to reduce the earliness of jobs. It is shown how unforced idle time can be inserted on the final machine. Several dispatching heuristics that have been used for the problem without unforced idle time were modified and tested. Several procedures were also developed that conduct a second pass to develop a sequence using dispatching rules. These procedures were also tested and were found to result in better solutions.

Abstract
Among the wide application areas that Virtual Reality (VR) can have a major impact, one is Education. However, this potential is still unexplored, and one of these gaps has to do with language learning. Listening activities, which are often only supported by audio, are thought of to be demanding area when it comes to learning a second or foreign language and so therefore an interesting area for VR to take place. This pilot study therefore presents the perceptions of foreign language teachers regarding a novel medium for delivering listening activities to their students: Virtual Reality technology. The results show that foreign language teachers are of the opinion that this technology can help motivate students and potentiate the student’s learning curve regarding the listening of a foreign or second language.

Abstract
The progressive decommissioning of large synchronous generators that should take place in face of increasing penetration ratios of Distributed Generation (DG) will demand additional control mechanisms for inertia provision and frequency and voltage regulation in the power system. The need to cope with increasing penetration ratios of DG in distribution grids, added to the necessity to integrate an expected massification of EV and distributed ESS, and to the necessity to enhance Power System resilience and controllability, makes the Smart-Transformer (ST) a suitable solution. In this paper it is demonstrated the feasibility of the ST to contribute to frequency control through the control of the resources available in the distribution AC/DC hybrid networks created from the ST. The feasibility of local droop controllers, acting on frequency and voltage magnitude of the AC/DC hybrid networks created from the ST, to achieve the aforementioned goal, is demonstrated through computational simulation.

Abstract
The area of professional training using virtual reality technologies has received considerable investment due to the advantages that virtual reality provides over traditional training. In this paper, we present an experiment whose goal was to analyse the impact that an additional stimulus has on the effectiveness of a virtual environment designed to train firefighters. The additional stimulus is a smell, more specifically the smell of burnt wood, which is consistent with the audiovisual content presented, and the effectiveness of the VE is measured through participant's feeling of presence, cybersickness, fatigue, stress and transfer of knowledge. The results indicate that, although the VE was successful in transferring knowledge, the addition of smell did not influence any of the measured variables. In the discussion section, we present the various factors that we believe have influenced this result. As future work, more experiments will be performed, with other stimuli, to understand better which stimuli increase participant's feeling of presence in the VE.
