Determination of stresses around a cylindrical single pile caused by horizontal...

This study was carried out with the aim of modeling in 2D, in plain strain, the movement of a soft cohesive soil around a pile, in order to enable the determination of stresses resulting along the pile, per unit length. The problem in study fits into the large deformations problem and can be due to landslide, be close of depth excavations, to be near of zones where big loads are applied in the soil, etc. In thi...

A statistical classifier for assessing the level of stress from the analysis of...

This paper describes an approach for assessing the level of stress of users of mobile devices with tactile screens by analysing their touch patterns. Two features are extracted from touches: duration and intensity. These features allow to analyse the intensity curve of each touch.We use decision trees (J48) and support vector machines (SMO) to train a stress detection classifier using additional data collected ...

The relationship between stress and conflict handling style in an ODR environment

Serie : Lecture notes in computer science, vol. 7856, ISSN 0302-9743 ; Up until now, most approaches to Online Dispute Resolution focused on "traditional" problems such as the generation of solutions, the support to negotiation or the definition of strategies. Although these problems are evidently valid and important ones, research should also start to consider new potential issues that arise from technologica...

Extracting behavioural patterns from a negotiation game

The work presented focuses not only on the behavioural patterns that influence the outcome of a negotiation, but also on the discovery of ways to predict the type of conflict used in the process and the stress levels of the actors. After setting up an experimental intelligent environment provided with sensors to capture behavioural and contextual information, a set of relevant data was collected and analysed, w...

Modelling stress recognition in conflict resolution scenarios

The current trend in Online Dispute Resolution focuses mostly on the development of technological tools that allow parties to solve conflicts through telecommunication means. However, this tendency leaves aside key issues, namely the context information that was previously available in traditional Alternative Dispute Resolution processes. The main weakness of this approach is that conflict resolution may become...

Non-invasive estimation of stress in conflict resolution environments

The current trend in Online Dispute Resolution focuses mostly on the development of technological tools that allow parties to solve conflicts through telecommunication means. However, this tendency leaves aside key issues, namely our concern with respect to context information that was previously available in traditional Alternative Dispute Resolution processes. The main weakness of this approach is that confli...

Developing dynamic conflict resolution models based on the interpretation of pe...

Proceedings of the 15th Portuguese conference on Artificial Intelligence - (EPIA 2011), Lisboa, Portugal, 2011. ; Conflict resolution is a classic field of Social Science research. However, with conflicts now also emerging in virtual environments, a new field of research has been developing in which Artificial Intelligence and particularly Ambient Intelligence are interesting. As result, the field of Online Di...
