[EN] How to design communications systems and its foundations depends on various factors such as the accessibility to learning resources, the academic environment and the audience itself. This article reports how the introduction of learning methodologies based on project based learning (PBL), practical devices and asynchronous working has modified the perception of the students about their learning aptitudes. The combination of traditional and offline sessions, with the PBL methodology to perform practical communications systems demonstrations based on professional SDR devices by group of students is presented and analysed in this article. The quantified outcome of their academic involveme…
A DGS gesture dictionary for modelling on mobile devices
2017
ABSTRACTInteractive or Dynamic Geometry System (DGS) is a tool that help to teach and learn geometry using a computer-based interactive environment. Traditionally, the interaction with DGS is based on keyboard and mouse events where the functionalities are accessed using a menu of icons. Nevertheless, recent findings suggest that such a traditional model of interaction has a steep learning curve and is inadequate to develop DGS for devices with multi-touch screens. Thus, we propose a new interaction model for DGS based on a gesture dictionary which enables the construction and manipulation of geometric objects without the need of accessing a menu of icons. The dictionary is divided into thr…
State of the art about use of IoT in education
2018
Every day the devices connected autonomously to the communication networks are increased. New applications arise for this type of interconnected objects, thus offering new alternatives for solutions of any kind, through the use of technology based on ubiquitous computing. That is why this work is inspired by these new technologies for its application in the educational field, with the purpose of contributing to the imposition of the use of IoT as a tool1 in the classroom.
“This is Just a Prototype”: How Ethics Are Ignored in Software Startup-Like Environments
2020
Artificial Intelligence (AI) solutions are becoming increasingly common in software development endeavors, and consequently exert a growing societal influence as well. Due to their unique nature, AI based systems influence a wide range of stakeholders with or without their consent, and thus the development of these systems necessitates a higher degree of ethical consideration than is currently carried out in most cases. Various practical examples of AI failures have also highlighted this need. However, there is only limited research on methods and tools for implementing AI ethics in software development, and we currently have little knowledge of the state of practice. In this study, we expl…
WhoSNext: Recommending Twitter Users to Follow Using a Spreading Activation Network Based Approach
2020
The huge number of modern social network users has made the web a fertile ground for the growth and development of a plethora of recommender systems. To date, recommending a new user profile X to a given user U that could be interested in creating a relationship with X has been tackled using techniques based on content analysis, existing friendship relationships and other pieces of information coming from different social networks or websites. In this paper we propose a recommending architecture - called WhoSNext (WSN) - tested on Twitter and which aim is promoting the creation of new relationships among users. As recent researches show, this is an interesting recommendation problem: for a …
A new project management approach for R&D software projects in the automotive industry - continuous V-model
2017
Most current work activities in R&D centres are innovative and dynamic, with project management acting as the discipline that governs them. The improvement of PM methods has become a necessity due to the following main factors: classical methodologies are increasingly difficult to apply, cutbacks in project duration are requested by organisations and customers, demands for product quality are continuously expanding. The paper examines how PM concepts are used in developed R&D projects, based on the V-model approach. It also introduces an enhanced new approach called Continuous V-model - CVM, based on agile concepts. The model has been applied on a real automotive R&D project and the resulte…
The wheel of collaboration tools
2006
Paper from the 2006 20th anniversary conference on Computer supported cooperative work We present a holistic framework for analyzing and specifying collaboration solutions, developed by an oil and gas company in response to practical needs in supporting integrated collaboration and information management. A typology of collaboration tool capabilities, termed the Wheel of Collaboration Tools (WCT), is described. We assess its contributions, and discuss areas of application and potential further development. Our intent is to stimulate discussion and research related to this type of collaboration modeling.

Mathematical modeling of a vehicle crash test based on elasto-plastic unloading scenarios of spring-mass models
2011
Published version of an article in the journal: The International Journal of Advanced Manufacturing Technology. Also available from the publisher on SpringerLink: htp://dx.doi.org/10.1007/s00170-010-3056-x This paper investigates the usability of spring which exhibit nonlinear force-deflection characteristic in the area of mathematical modeling of vehicle crash. We present a method which allows us to obtain parameters of the spring-mass model basing on the full-scale experimental data analysis. Since vehicle collision is a dynamic event, it involves such phenomena as rebound and energy dissipation. Three different spring unloading scenarios (elastic, plastic, and elasto-plastic) are covered…
Bond graph modeling and simulation of wind turbine systems
2013
Published version of an article in the journal: Journal of Mechanical Science and Technology. Also available from the publisher at: http://dx.doi.org/10.1007/s12206-013-0435-x This paper addresses the problem of bond graph methodology as a graphical approach for the modeling of wind turbine generating systems. The purpose of this paper is to show some of the benefits the bond graph approach has, in contributing a model for wind turbine systems. We will present a nonlinear model of a wind turbine generating system, containing blade pitch, drive train, tower motion and generator. All which will be modeled by means of bond graph. We will especially focus on the drive train, and show the differ…
