The game of football demands new computational approaches to measure individual and collective performance. Understanding the phenomena involved in the game may foster the identification of strengths and weaknesses, not only of each player, but also of the whole team. The development of assertive quantitative methodologies constitutes a key element in sports training. In football, the predictab...

In this paper, we propose a refinement of Chevallard’s algebraic modeling while still fully agreeing with his position that it is a key process in knowing mathematics. In doing so, based on our empirical study, we claim that: 1) there are two other stages in the algebraic modeling process; 2) it is nonlinear; and 3) partial models are constructed as well. Research on Chevallard's modeling persp...

We present a novel and fast algorithm to solve the Perspective-n-Point problem. The PnP problem estimating the pose of a calibrated camera based on measurements and known 3D scene, is recasted as a minimization problem of the Object Space Cost. Instead of limiting the algorithm to perspective cameras, we use a formulation for general camera models. The minimization problem, together with a quat...

In this paper the architecture and implementation of Cooperative Information Agents (CIA) is described. Taking a language-action perspective to the design of CIAs allows for the specification of obligations and authorizations, and results in the separation of tasks (things the agentmust do) and contracts (mutually agreed commitments to the course of communication). The architecture describes th...

Good communication is the basis for effective cooperation. An area where cooperation is essential is multidisciplinary healthcare. In this paper we will present a research project that aims at promoting effective multidisciplinary communication in a healthcare environment. We will answer the question of whether empirical modelling of the communication and cooperation patterns can be done based ...

When people or organizations provide information, they make choices regarding what they include and how they represent it. These two aspects combined (the content and the stance) represent a perspective. Investigating perspectives can provide useful insights into the reliability of information, changes in viewpoints over time, shared beliefs among social or political groups and contrasts with o...

This paper examines the under-investigated well-being impacts of arts and music events attendance, in both a live virtual capacity. Using eudaimonia hedonia as measure for well-being, three objectives were investigated; 1) Do meet attendees eudemonic hedonic needs? 2) 3) How do art compare meeting The study focused on attendee’s experiences having attended events. nine semi-structured interview...

In this paper, I seek to revitalize the concept of happiness by conceptualizing it as a relational and instantaneous phenomenon with both existential, ethical political dimensions. Happiness hap-ens – in through encounters, does so when we least expect it. Drawing on Bachelard’s writings ‘the instant’, well Gumbrecht’s Rosa’s much related concepts ‘presence’ ‘resonance’, attempt formulate more ...

The discussion of models and modeling in this chapter is based, in part, on the results of research on students’ understanding of quantum mechanics (Gardner, 2002) and research designed to probe students’ ability to visualize the rotation of organic molecules (Briggs, 2004). Our perspective on models and modeling has also been influenced by work in both physics education (Halloun, 1996) and mat...
