Diseño de una estación didáctica para el control de temperatura mediante un controlador industrial

En este proyecto el problema es lograr controlar la temperatura de un horno de resistencia mediante un controlador industrial, no en el sentido de la existencia de sistemas que permitan este tipo de control sino en poder brindar un espacio de simulación de entornos donde se puedan requerir conocimientos de instrumentación industrial los estudiantes. La solución a este problema es un sistema de control adecuado para simulaciones en las aulas y demás que permita transmitir los resultados, lo cual permite interiorizar más fácilmente los conceptos vistos en clase. Los pasos que se siguieron para llegar al diseño y construcción de un sistema que controle la temperatura fueron, primero determinar metodologías de medición de temperatura que se iban a emplear teniendo en cuenta que sean de uso común en la industria y se puedan aplicar proceso de formación. Segundo, Seleccionar los elementos funcionales del sistema de control de temperatura en el manejo del equipo dentro de un contexto académico mirando la utilidad en la Escuela de Tecnología Mecánica. Tercero, Establecer los requerimientos necesarios para la realización de los planos eléctricos y constructivos de la estación de control de temperatura mediante la observación de hornos industriales localizados en la facultad de ingeniería mecánica de la Universidad Tecnológica de Pereira. Finalmente, con el sistema funcionando se realizaron los ajustes de setpoint, histéresis y calibración con el sistema de extracción de datos para graficar el comportamiento del sistema de control. Todo el proceso de diseño y construcción da como resultado un trabajo de investigación que no solo crea un dispositivo de medición más asequible sino también una experiencia muy completa en la parte de instrumentación y procesamiento de señales, afianzado así lo aprendido durante el periodo de formación

I didn't say that!:Uses of SAY in mediation discourse

While several taxonomies of meta-discourse exist, none clearly explains speakers’ strategies in mediation. Mediators, however, seem to rely a lot on meta-discourse to manage the argument while preserving their neutrality. This article proposes corpus analyses to detect mediation participants’ discourse strategies and highlight the role and function of a meta-discourse element – the verb ‘to say’. This paper is a first step towards the elaboration of a taxonomy for the analysis of argumentative meta-discourse, and brings new insights in meta-discourse in argumentative dialogues and mediation discourse in general.<br/

A System for Dispute Mediation:The Mediation Dialogue Game

We propose a dialogue game for mediation and its formalization in DGDL. This dialectical system is available as software through Arvina for automatic execution. This work expands the literature in dialectical systems, in particular those for more than two players, and shows the practical impact on mediation activity through the opportunity offered to mediators once implemented

Theoretical foundations for illocutionary structure parsing

Illocutionary structure in real language use is intricate and complex, and nowhere more so than in argument and debate. Identifying this structure without any theoretical scaffolding is extremely challenging even for humans. New work in Inference Anchoring Theory has provided significant advances in such scaffolding which are helping to allow the analytical challenges of argumentation structure to be tackled. This paper demonstrates how these advances can also pave the way to automated and semi-automated research in understanding the structure of natural debate. This paper is the extended version of the paper presented at the 11th International Conference on Computational Models of Natural Argument (CMNA 2013), 14 June 2013, Rome, Italy. It reports on the initial steps of a project on argument mining from dialogue. Note that since then the corpus size and the annotation scheme have evolved, however, the method presented here is still valid and the project has developed accordingly

Automatically identifying transitions between locutions in dialogue

International audienceThe contribution of this paper is theoretical foundations for dialogical argument mining, as well as initial implementation in software for dialogue processing. Automatically identifying the structure of reasoning from natural language is extremely demanding. Our hypothesis is that the structure of dialogue can yield additional clues as to argument structures that are created and cocreated. Our work has been performed using the MM2012 corpus in OVA+

3D Quantification of Ultrasound Images: Application to Mouse Embryo Imaging In Vivo

International audienceHigh frequency ultrasound imaging has become an effective tool for anatomical mice studies. This work is focused on 3D quantification of mouse embryo development to extract pertinent information of its evolution. A series of B-Scan ultrasound images was acquired at different spatial positions along the embryo. A 3D deformable model was used to segment the images. A pregnant female mouse at embryonic day 14.5 was imaged with an ATL HDI 5000, 7-15MHz linear array. The probe was moved by a step by step motor along the abdomen of the mouse. 3D segmentation results are presented including volume quantification of the embryo

Corpus resources for dispute mediation discourse

Dispute mediation is a growing activity in the resolution of conflicts, and more and more research emerge to enhance and better understand this (until recently) understudied practice. Corpus analyses are necessary to study discourse in this context; yet, little data is available, mainly because of its confidentiality principle. After proposing hints and avenues to acquire transcripts of mediation sessions, this paper presents the Dispute Mediation Corpus, which gathers annotated excerpts of mediation dialogues. Although developed as part of a project on argumentation, it is freely available and the text data can be used by anyone. This first-ever open corpus of mediation interactions can be of interest to scholars studying discourse, but also conflict resolution, argumentation, linguistics, communication, etc. We advocate for using and extending this resource that may be valuable to a large variety of domains of research, particularly those striving to enhance the study of the rapidly growing activity of dispute mediation
