Virtual Instruments in Dimensional Metrology

During the last five years, in order to improve understanding of content related to "Coordinate Metrology", the Laboratorio de Metrología y Metrotecnia (LMM) from the Polytechnic University of Madrid offers its PhD students, as a course work, the construction of a virtual instrument. This virtual instrument simulates the imaging of a part to be measured by optical dimensional metrology instruments (microscopes, profile projectors, vision machines). The LMM provides students with images similar to those they would obtain with real instrumentation for the instrument adjustment and calibration process. Working with these images, students should determine the adjustment parameters of the virtual instrument. Once these parameters are set, the student can perform the proper calibration of the virtual instrument. Beyond this process, the instrument is already able to perform traceable measurement. In order to do that, LMM offers students some images of parts. Students should perform some measurements using those images and estimate the corresponding uncertainties.

Supervised classification of minimally invasive surgery psychomotor competence based on instruments motion analysis

Background Objective assessment of psychomotor skills has become an important challenge in the training of minimally invasive surgical (MIS) techniques. Currently, no gold standard defining surgical competence exists for classifying residents according to their surgical skills. Supervised classification has been proposed as a means for objectively establishing competence thresholds in psychomotor skills evaluation. This report presents a study comparing three classification methods for establishing their validity in a set of tasks for basic skills’ assessment. Methods Linear discriminant analysis (LDA), support vector machines (SVM), and adaptive neuro-fuzzy inference systems (ANFIS) were used. A total of 42 participants, divided into an experienced group (4 expert surgeons and 14 residents with >10 laparoscopic surgeries performed) and a nonexperienced group (16 students and 8 residents with <10 laparoscopic surgeries performed), performed three box trainer tasks validated for assessment of MIS psychomotor skills. Instrument movements were captured using the TrEndo tracking system, and nine motion analysis parameters (MAPs) were analyzed. The performance of the classifiers was measured by leave-one-out cross-validation using the scores obtained by the participants. Results The mean accuracy performances of the classifiers were 71 % (LDA), 78.2 % (SVM), and 71.7 % (ANFIS). No statistically significant differences in the performance were identified between the classifiers. Conclusions The three proposed classifiers showed good performance in the discrimination of skills, especially when information from all MAPs and tasks combined were considered. A correlation between the surgeons’ previous experience and their execution of the tasks could be ascertained from results. However, misclassifications across all the classifiers could imply the existence of other factors influencing psychomotor competence.

Accessibility instruments for planning practice: bridging the gap between academic research and decision-making.

One of the core objectives of urban planning practice is to provide spatial equity in terms of opportunities and use of public space and facilities. Accessibility is the element that serves this purpose as a concept linking the reciprocal relationship between transport and land use, thus shaping individual potential mobility to reach the desired destinations. Accessibility concepts are increasingly acknowledged as fundamental to understand the functioning of cities and urban regions. Indeed, by introducing them in planning practice, better solutions can be achieved in terms of spatial equity. The COST Action TU1002 "Accessibility instruments for planning practice" was specifically designed to address the gap between scientific research in measuring and modelling accessibility, and the current use of indicators of accessibility in urban planning practice. This paper shows the full process of introducing an easily understandable measure of accessibility to planning practitioners in Madrid, which is one of the case studies of the above-mentioned COST action. Changes in accessibility after the opening of a new metro line using contour measures were analyzed and then presented to a selection of urban planners and practitioners in Madrid as part of a workshop to evaluate the usefulness of this tool for planning practice. Isochrone maps were confirmed as an effective tool, as their utility can be supplemented by other indicators, and being GIS-based, it can be easily computed (when compared with transport models) and integrated with other datasets.

Do you feel what I feel? : emotional development in children with ID

Do you feel what I feel? Emotional development in children with ID is a study that has emerged as a need to deepen the knowledge on this area. It has focused in a case study methodology with the use of three validated instruments to a sample of thirty-four children, twenty attending the 1st cycle and fourteen attending the 2nd, in two school groupings of Castelo Branco city. Seventeen of them have mild intellectual disability and seventeen are “normal”, aged between 8 and 14. The research has been developed in order to give answers to questions related with the way that children with intellectual disability (ID) express, identify and regulate their emotions. The results suggest that children with intellectual disability identify emotions, in a general way, the same way that “normal” children do, nevertheless, there are some difficulties in the understanding and organization of coping strategies.

Synthèse systématique des écrits : les instruments d’évaluation de la comorbidité psychiatrique présentée par les adolescent(e)s

Ce mémoire présente les résultats d’une synthèse systématique (SS) des écrits traitant des instruments d’évaluation multidimensionnelle des troubles concomitants qui peuvent être présentés par les adolescent(e)s. La SS a permis d’identifier 11 instruments en mesure d’évaluer les troubles comorbides de l’Axe I du DSM-IV, incluant chaque fois les troubles liés à l’utilisation de substances psychoactives (TUS). Une fois les instruments répertoriés, une seconde recherche fut effectuée afin identifier les études les ayant mis à l’épreuve du point de vue de leur validité et de leur fidélité diagnostique : 57 études furent identifiées. La robustesse méthodologique de ces études fut analysée à l’aide de la grille du QUADAS-2 et 47 études furent retenues pour l’échantillon final. Les résultats sont présentés par diagnostics (troubles liés à l’utilisation des substances (TUS) (obligatoire), trouble d’anxiété généralisée (TAG), épisode dépressif majeur (ÉDM), troubles des conduites (TC), trouble du déficit de l’attention /hyperactivité (TDA/H), état de stress post-traumatique (ÉSPT) et par instrument retenu. Suite à l’analyse des données recueillies, il s’avère difficile de comparer les instruments les uns aux autres, étant donnée la très grande diversité des échelles qu’ils contiennent, ainsi que les devis fort différents des études qui les ont mis à l’épreuve. Par contre, deux instruments se distinguent par la robustesse méthodologique des études à leur sujet, ainsi que leur excellente performance globale. Il s’agit du ChIPS et du K-SADS.
