Abstract
Current information and communication technologies, including the internet and its services (web 2.0, email, conferences at a distance, etc.) have opened new perspectives in the field of education, by promoting communication and interaction between all participants at a distance. It is not the technology itself that will define the quality of teaching and learning in distance education, but the methodological approach that supports it. This paper aims to propose a methodological framework to implement in distance education modules supported by online pedagogy elements linked to innovative teaching methodologies. Its goal is to bring some contributions to those who are in charge of course design, providing a useful framework to improve active and technology enhanced collaborative learning in similar environments.

Abstract
With the emergence of the Industry 4.0 concept, or the fourth industrial revolution, the industry is bearing witness to the appearance of more and more complex systems, often requiring the integration of various new heterogeneous, modular and intelligent elements with pre-existing legacy devices. This challenge of interoperability is one of the main concerns taken into account when designing such systems-of-systems, commonly requiring the use of standard interfaces to ensure this seamless integration. To aid in tackling this challenge, a common format for data exchange should be adopted. Thus, a study to select the foundations for the development of such a format is hereby presented, taking into account the specific needs of four different use cases representing varied key European industry sectors.

Abstract
In this paper we introduce the problem of planning for perception of a target position. Given a sensing target, the robot has to move to a goal position from where the target can be perceived. Our algorithm minimizes the overall path cost as a function of both motion and perception costs, given an initial robot position and a sensing target. We contribute a heuristic search method, PA*, that efficiently searches for an optimal path. We prove the proposed heuristic is admissible, and introduce a new goal state stopping condition.

Abstract
Too often illustrating and visualizing 3D geological concepts are performed by sketching in 2D mediums, which may limit drawing performance of initial concepts. Here, the potential of expeditious geological modeling brought by hand gestures is explored. A spatial interaction system was developed to enable rapid modeling, editing, and exploration of 3D layer-cake objects. User interactions are acquired with motion capture and touch screen technologies. Virtual immersion is guaranteed by using stereoscopic technology. The novelty consists of performing expeditious modeling of coarse geological features with only a limited set of hand gestures. Results from usability-studies show that the proposed system is more efficient when compared to a windows-icon-menu-pointer modeling application.

Abstract
Internationalization has been adopted by many companies, regardless of size, to boost their growth. Although the Uppsala model and the network approach have been extensively used to analyze how small firms internationalize their operations, this chapter addresses how a small firm of the clean carpentry industry managed to overcome an economic slowdown of its domestic market and boosted its growth. This chapter uses a case study approach that is framed on a literature review covering internationalization of SMEs, entrepreneurship, the importance of the network approach, the search of opportunities and trust, and relationship orientation to show how a firm abandoned its passive behavior and its focus on the domestic market to proactively address the international market following an entrepreneurial perspective.
