Motorized circular rail with RGB-D sensor on cart for physical rehabilitation

This paper introduces a motorized circular rail managing the movement of two carts equipped with an RGB-D sensor each. The proposal is aimed at continuously tracking a person who is undergoing a series of physical rehabilitation exercises from two different viewpoints to monitor if the exercises are being correctly conducted. More concretely, this work offers all details of the trajectory calculation for safe movement of both carts on the motorized circular rail. Then, two study cases are presented to show the efficiency of the control algorithms implemented.AEI - Agencia Estatal de Investigação(TIN2016-79100-R)This work was partially supported by Ministerio de Ciencia, Innovación y Universidades, Agencia Estatal de Investigación (AEI) / European Regional Development Fund (FEDER, UE) under DPI2016-80894-R and TIN2016-79100-R grants

A planner for supporting countermeasures in large scale cyber attacks

We are in a period where Computer Science leads lots of activities in many fields and the number of Cyber activities is growing up every day. Safety and security issues are going to be considered the most important properties in computer systems. But in the age of Cyber lives, Cyber Crimes are an everyday increasing problem. Thinking in large-scale, enacting Cyber attacks, or even countermeasures to attacks involving different Countries, may be compared to war declaration. In this scenario it is clear the problem of scheduling large-scale countermeasures to Cyber attacks. We propose here an automatic way to plan countermeasures to Cyber Attacks, that takes into account International laws and treaties as enabling condition to actions. The planning is based on a formal, multi-agent based, model of Actors in a Cyber scenario and on formal reasoning by counterexamples. © Springer International Publishing AG 2018

Improving the Usability of a MAS DSML

© 2019, Springer Nature Switzerland AG.Context: A significant effort has been devoted to the design and implementation of various domain-specific modeling languages (DSMLs) for the software agents domain. Problem: Language usability is often tackled in an ad-hoc way, with the collection of anecdotal evidence supporting the process. However, usability plays an important role in the productivity, learnability and, ultimately, in the adoption of a MAS DSML by agent developers. Method: In this chapter, we discuss how the principles of The “Physics” of Notations (PoN) can be applied to improve the visual notation of a MAS DSML, called SEA_ML and evaluate the result in terms of usability. Results: The evolved version of the language, SEA_ML++, was perceived as significantly improved in terms of icons comprehensibility, adequacy and usability, as a direct result of employing the principles of PoN. However, users were not significantly more efficient and effective with SEA_ML++, suggesting these 2 properties were not chiefly constrained by the identified shortcomings of the SEA_ML concrete syntax
