Complex Automated Negotiations

Abstract
Internally agents may use argumentation for both (i) reasoning about what to believe (i.e. theoretical reasoning) and/or (ii) for deciding what to do (i.e. practical reasoning). Despite existing differences between both, from a standpoint of first-personal reflection, a set of considerations for and against a particular conclusion are drawn on both [1]. On the other hand, concerning the types of agents' dialogues (e.g. Deliberation, Negotiation, Persuasion, Inquiry, Information-seeking dialogues), while a clear distinction between each one exist, most of the agents' dialogue occurrences involve mixtures of dialogue types. © Springer-Verlag Berlin Heidelberg 2013.

Abstract
Energy systems worldwide are complex and challenging environments. Multi-agent based simulation platforms are increasing at a high rate, as they show to be a good option to study many issues related to these systems, as well as the involved players at act in this domain. In this scope the authors research group has developed three multi-agent systems: MASCEM, which simulates the electricity markets; ALBidS that works as a decision support system for market players; and MASGriP, which simulates the internal operations of smart grids. To take better advantage of these systems, their integration is mandatory. For this reason, is proposed the development of an upper-ontology which allows an easier cooperation and adequate communication between them. Additionally, the concepts and rules defined by this ontology can be expanded and complemented by the needs of other simulation and real systems in the same areas as the mentioned systems. Each system's particular ontology must be extended from this top-level ontology. © Springer International Publishing Switzerland 2013.

Abstract
The Spin-Up project has the objective of determining what sort of entrepreneurship training and coaching program will contribute to the development of key entrepreneurial skills, both technical and behavioural, essential to enable and leverage university spin-off growth. University spin-off firms (USOs) tend to grow at a slower pace than corporate spin-offs or other young high-technology firms, which underlines the need for the project. The Spin-Up project is funded by the European Commission within the scope of the Erasmus Program (Enterprise and University cooperation) / Lifelong Learning Program. The project commenced in 2011, and the consortium is made up by five entities from three countries and one associated partner country. 99 face-to-face interviews and surveys of CEOs and members of USO management teams revealed that a number of entrepreneurial skills were missing and hampering growth, namely skills (top 10) to: gain financial capital; internationalize; increase sales; be financially literate; manage marketing; manage human resources; manage operations; understand economic principles of business; grow based on strategic management; and understand an approach keen on intellectual ownership protection. These findings guided the development of the training program, to be delivered to USO CEOs and other USO senior managers. Full pilot training sessions have already been delivered in the Netherlands, in Finland, and in Portugal. The training was delivered based on: 1) initial exploratory questions; 2) subsequent providing of background theory; and 3) finalizing with further practical questions on the subject matter. In this way, engagement of the spin-off firms was increased throughout and the training had a very practical approach, centered on problem-solving and real life examples, challenging participants to think about their day-to-day issues hampering growth. The areas in need of specific training were defined as being innovation, marketing and sales; overall strategy; finance; internationalization strategy; and leadership and human resource management. Networking opportunities occurred between peers during the training sessions and also with various key specialists, like a business angel (in Portugal) and venture capitalist (in the Netherlands). In terms of what the consortium partners have produced, tangible materials include training manuals and case studies, to support the training effort.

PROCEEDINGS OF THE 2013 8TH IBERIAN CONFERENCE ON INFORMATION SYSTEMS AND TECHNOLOGIES (CISTI 2013)

Abstract
Developing Poker agents that can compete at the level of a human expert can be a challenging endeavor, since agents' strategies must be capable of dealing with hidden information, deception and risk management. A way of addressing this issue is to model opponents' behavior in order to estimate their game plan and make decisions based on such estimations. In this paper, several hand evaluation and classification techniques are compared and conclusions on their respective applicability and scope are drawn. Also, we suggest improvements on current techniques through Monte Carlo sampling. The current methods to deal with risk management were found to be pertinent concerning the agent's decision-making process; nevertheless future integration of these methods with opponent modeling techniques can greatly improve overall Poker agents' performance.

Abstract
In the last decade, Synthetic Aperture Radar Interferometry (InSAR) has become operational as a technique that allows remote detection of deformation at the Earth's surface. Analysis of time series of SAR images extends the area where InSAR can be successfully applied and also permits detection of smaller displacements through the reduction of error sources. Stanford Method for Persistent Scatterers (StaMPS) InSAR implementation, which is based on the processing of multi-temporal SAR data, is widely used for ground deformation monitoring. This is due mainly to its proven reliability and freeware distribution among the scientific community. However, some issues can make the interpretation of the results a difficult task: StaMPS supports data processing based on command prompt, which increases the difficulty of usage by users not familiar with the specific programming language that supports StaMPS. Moreover, several visualization tasks are not implemented in the standard approach requiring that each user develop its own code for visualization and interpretation purposes. In this paper, we present viStaMPS, a new visual application developed to enhance the visualization, manipulation and exportation of StaMPS results. The programmed application is developed in Matlab through the Graphical User Interface (GUI) and no coding is required for running it, which avoids any programming language knowledge for standard uses. The included graphical interface is very versatile allowing the user to choose among several features: visualization, manipulation and exportation of data which are not available in the original StaMPS.

Cutting-Edge Technologies in Higher Education

Abstract
New mobile platforms, connected seamlessly to the Internet via wireless access, become increasingly more powerful as each day passes. Smartphones and tablet computers, as well as other ultraportable devices, have already gained enough critical mass to be considered mainstream devices, being present in the daily lives of millions of higher education students. Whole firms, devoted solely to developing high-quality and high engagement content to these devices, have emerged, populating an application market of thousands of teaching applications (apps) focused on diverse higher education topics, from physics and calculus to anatomy and law. Many universities throughout the world have already adopted or are planning to adopt mobile technologies in many of their courses as a better way to connect students with the subjects they are studying. These new mobile platforms allow students to access content anywhere/anytime to immerse himself/herself into that content (alone or interacting with teachers or colleagues via web communication forms) and to interact with that content in ways that were not previously possible (via touch and voice recognition technologies, for instance). The study of such technologies and their possible uses for higher education, as well as the impacts they can have on stimulating more active participation and engagement with the course subjects and research in higher education, while at the same time fostering collaboration among students and even different institutions, is the goal of the proposed chapter. Through the evaluation of the teacher/student acceptance and adoption of such mobile technologies, this chapter plans to provide a thorough overview of the possibilities and consequences of mobile learning in higher education environments as a gateway to ubiquitous learning - perhaps the ultimate form of learner engagement, since it allows the student to learn, access and interact with important content in any way or at any time or place she/he might want.
