New Trends in Detectors for Medical Imaging
2010
The improvement of medical imaging instrumentation is based both on the enhancement of the performance of the detectors employed in their construction and on the development of novel techniques and methods that allow full exploitation of the advantages of the new instrumentation.
A fuzzy method to repair infeasibility in linearly constrained problems
2001
Abstract In this paper we introduce a fuzzy method to deal with infeasibility in linearly constrained programs. Given an infeasible instance, we determine how much we should perturb the right-hand side coefficients in order to attain feasibility and propose a ‘feasible reformulation’ of the problem. Although we prove that our algorithm always finds such a reformulation the convenience of using it can be decided by the analyst. By this, we mean that the method also provides a simple way to compute lower bounds on the changes on every right-hand side coefficient, and if the decision maker considers that some of the magnitudes are unacceptable, he or she simply stops at this step. We think tha…
Human-centred Assembly: A Case Study for an Anthropocentric Cyber-physical System
2014
Abstract To engineer the factory of the future the paper argues for an anthropocentric cyber-physical reference model that assimilate in an integrated, dynamic, structural and functional way all the required components (i.e. physical, computational and human) of a synthetic hybrid system. This is due to the real need to design large-scale complex systems that accommodate the latest achievements in factory automation where the human is not merely playing a simple and clear role inside the control-loop, but is becoming a composite factor in a highly automated system (“man-in-the-mesh”). The concept is demonstrated by instantiating our anthropocentric cyber-physical reference model in a concre…
Economic Aspects in the Treatment of Schizophrenia in Italy: Cost Consequences of an Early Long-acting Injectable Anti-Psychotics (lais) Approach
2017
PurposeThe aim of this analysis was to evaluate the economic consequences of a new treatment approach in the treatment of schizophrenia in the Italian setting. In terms of direct costs, in Italy was estimated that the main driver were represented by hospitalization and residential cost (71% of total direct cost per patient), followed by semi-residential services (13%), anti-psychotic and other drugs (8%) and ambulatory services (8).MethodsA probabilistic cost consequence model was developed to estimate the potential cost reductions derived from an early treatment with atypical long-acting injectable anti-psychotics (aLAIs) drugs. A systematic literature review was carried out to identify di…
Who and how? : Preservice teachers as active agents developing professional identities
2016
Abstract This study is part of an ongoing action research project with preservice class teachers in Finland. The study aims to better understand the forms agency takes in preservice teachers' professional identity development. Through the dialogical analysis of student assignments, this study outlines how student teachers are active within their own development and the way in which experiences are drawn on as preservice teachers exert their identity-agency. The results of this study provide a relational picture of identity development highlighting the way in which identity-agency is contextualized, potentially nourished by the relationships between self and other and dependent on experience.
Creating Digital Musical Instruments With and for Children: Including Vocal Sketching as a Method for Engaging in Codesign
2020
International audience; A class of master of science students and a group of preschool children codesigned new digital musical instruments based on workshop interviews involving vocal sketching, a method for imitating and portraying sounds. The aim of the study was to explore how the students and children would approach vocal sketching as one of several design methods. The children described musical instruments to the students using vocal sketching and other modalities (verbal, drawing, gestures). The resulting instruments built by the students were showcased at the Swedish Museum of Performing Arts in Stockholm. Although all the children tried vocal sketching during preparatory tasks, few …
Implantación de recursos didácticos digitales en asignaturas de Organización de Empresas
2013
El objetivo de este artículo es presentar el protocolo de implantación de diversas herramientas didácticas, así como el nivel de satisfacción de los estudiantes que las utilizan. Los resultados muestran, primero, que no es posible crear un único protocolo aplicable a todos los recursos, debido a las diferencias en los objetivos didácticos existentes. Segundo, la valoración que los estudiantes hacen de la utilización de los recursos es muy positiva, aunque existen algunas diferencias entre las distintas herramientas. Estos resultados permiten mejorar los recursos y adecuarlos al perfil de los estudiantes para que éstos puedan sacar el mayor provecho posible.
The Asynchronous Leontief Model
1992
International audience; The traditional dynamic Leontief model is synchronous: every vertex acts simultaneously. A model with delays of action has been proposed, but it still remains synchronous. In this paper we propose an asynchronous version of the model that allows realistic computations. We fiurnish an algorithm and a program.
Quantitative Analysis of Dynamic Association in Live Biological Fluorescent Samples
2014
Determining vesicle localization and association in live microscopy may be challenging due to non-simultaneous imaging of rapidly moving objects with two excitation channels. Besides errors due to movement of objects, imaging may also introduce shifting between the image channels, and traditional colocalization methods cannot handle such situations. Our approach to quantifying the association between tagged proteins is to use an object-based method where the exact match of object locations is not assumed. Point-pattern matching provides a measure of correspondence between two point-sets under various changes between the sets. Thus, it can be used for robust quantitative analysis of vesicle …
Rank response functions in an online learning environment
2021
Abstract We estimate rank response functions after receiving rank-order feedback in an online learning platform. We find that the shapes of the rank response functions depend on the outcome measure under consideration. For our effort measure, i.e., whether learners continue to interact with the platform, we can reject a linear rank response function and find significant evidence of a U-shaped relationship. For our performance measure, i.e., correctly solved exercises, we find no clear pattern overall but suggestive evidence for a linearly decreasing rank response function for individuals in the lower half of the ability distribution, i.e., the lower the rank the lower the performance.
