Carbon Nanotubes Dispersion Assessment in Nanocomposites by Means of a Pulsed Thermographic Approach
2020
The extensive production of polymer composites reinforced by carbon nanotube is limited by the absence of non-destructive evaluation (NDE) methods capable of assessing product quality to guarantee compliance with specifications. It is well known that the level of dispersion of carbon nanotubes (CNTs) in the polymer matrix is the parameter that, much more than others, can influence their enhancement capabilities. Here an active Infrared Thermography Non Destructive Testing(IR-NDT) inspection, joined with pulsed phase thermography (PPT), were applied for the first time to epoxy-CNT composites to evaluate the level of dispersion of the nanoparticles. The PPT approach was tested on three groups…
Enabling robotic adaptive behaviour capabilities for new industry 4.0 automated quality inspection paradigms
2020
The seamless integration of industrial robotic arms with server computers, sensors and actuators can revolutionise the way in which automated non-destructive testing (NDT) is performed and conceived. Achieving effective integration and realising the full potential of robotic systems presents significant challenges, since robots, sensors and end-effector tools are often not necessarily designed to be put together and form a holistic system. This paper presents recent breakthroughs, opening up new scenarios for the inspection of product quality in advanced manufacturing. Many years of research have brought to software platforms the ability to integrate external data acquisition instrumentatio…
A GRASP heuristic for the mixed Chinese postman problem
2002
Abstract Arc routing problems (ARPs) consist of finding a traversal on a graph satisfying some conditions related to the links of the graph. In the Chinese postman problem (CPP) the aim is to find a minimum cost tour (closed walk) traversing all the links of the graph at least once. Both the Undirected CPP, where all the links are edges that can be traversed in both ways, and the Directed CPP, where all the links are arcs that must be traversed in a specified way, are known to be polynomially solvable. However, if we deal with a mixed graph (having edges and arcs), the problem turns out to be NP -hard. In this paper, we present a heuristic algorithm for this problem, the so-called Mixed CPP…
Introducing Usability in a Conceptual Modeling-Based Software Development Process
2012
Usability plays an important role to satisfy users? needs. There are many recommendations in the HCI literature on how to improve software usability. Our research focuses on such recommendations that affect the system architecture rather than just the interface. However, improving software usability in aspects that affect architecture increases the analyst?s workload and development complexity. This paper proposes a solution based on model-driven development. We propose representing functional usability mechanisms abstractly by means of conceptual primitives. The analyst will use these primitives to incorporate functional usability features at the early stages of the development process. Fo…
An analysis of the scientific productivity and visibility of publications on usability (1971-2005)
2009
Aims: To analyse usability-related articles published in the period 1971-2005 from a bibliometric point of view. Methods: A search for articles was made in the CSIC databases, the Social Science Citation Index, Science Citation Index, PsycInfo, MEDLINE and Inspec databases, using ad hoc search strategies designed for each. Contribution, specific contribution and overlap indices were calculated, as were the indicators of change in scientific production, the productivity of institutions and journals, and the distribution of journals by area of knowledge. Results: An exponential increase in the number of published articles was recorded, with the highest increase seen over the last five years. …
La Inspección Educativa como órgano de evaluación y supervisión del profesor de música en la Educación Secundaria Obligatoria en centros de la Comuni…
2012
El presente trabajo de investigación pretende comprobar en qué medida influye el órgano oficial dependiente de las Administraciones educativas, La Inspección, en la evaluación y la supervisión de la tarea docente, centrándose en la didáctica de la música en la etapa de la Educación Secundaria Obligatoria. Para ello, se han valorado los diferentes modelos de evaluación llevados a cabo en países de nuestro entorno, comparando en alguna medida, con lo realizado en nuestra Comunidad. La investigación revela infinidad de cuestiones tales como qué función real tiene la evaluación de los docentes o si la rendición de cuentas propuesta por la Administración tendría un objeto formativo o más bien de…
