Haptic and Visual Feedback Assistance for Dual-Arm Robot Teleoperation in Surface Conditioning Tasks
2020
Contact driven tasks, such as surface conditioning operations (wiping, polishing, sanding, etc.), are difficult to program in advance to be performed autonomously by a robotic system, specially when the objects involved are moving. In many applications, human-robot physical interaction can be used for the teaching, specially in learning from demonstrations frameworks, but this solution is not always available. Robot teleoperation is very useful when user and robot cannot share the same workspace due to hazardous environments, inaccessible locations, or because of ergonomic issues. In this sense, this article introduces a novel dual-arm teleoperation architecture with haptic and visual feedb…
Ambientes híbridos de aprendizaje
2022
Desde la línea de reflexión y trabajo sociocultural, entroncada en los aportes de Vigostky (2000), no existe aprendizaje al margen del contexto donde se aloja el proceso; esto es, el entorno educativo no es un decorado sin más alrededor de quien aprende -y de quien enseña-, sino parte de su explicación y su motor de desarrollo; no hay aprendizaje en abstracto: se aprende en un contexto que define las limitaciones y posibilidades de desarrollo. ¿Cómo esta idea sustancial puede tener cabida al pensar la relación entre la educación y la tecnología en la actualidad?. La respuesta a la interrogante anterior parte de la comprensión de un pequeño, pero significativo giro en la concepción de la res…
Air stable hybrid organic-inorganic light emitting diodes using ZnO as the cathode
2007
An air stable hybrid organic-inorganic light emitting device is presented. This architecture makes use of metal oxides as charge injecting materials into the light emitting polymer, avoiding the use of air sensitive cathodes commonly employed in organic light emitting diode manufacturing. We report the application of zinc oxide as a cathode in an organic light emitting device. This electroluminescent device shows high brightness levels reaching 6500 cd/m2 at voltages as low as 8 V. Compared to a conventional device using low workfunction metal cathodes, our device shows a lower turn-on voltage and it can operate in air.
¿Cómo funciona el sistema de innovación del sector cerámico español?
2013
[EN]: In this article we apply the functions of innovation systems framework to assess its appropriateness to characterise the innovation activity of the tile industry in Castellón. This framework is based on idea that a well functioning innovation system requires that a number of key activities take place. If this occurs innovative output is higher. Our analysis provides a deeper understanding of the role of innovation as a strategic option in a mature industry in the context of globalisation. By applying this new theoretical approach to study innovation and highlighting the functions that the system requires, we shown the constraints, inertias, challenges and opportunities that the innova…

La Digitalización de la Educación en Pandemia. Mirada del docente peruano
2022
La respuesta educativa mundial ante la pandemia se ha basado en la digitalización de los procesos de aprendizaje. Estos procesos han sido disímiles, en su gran mayoría por ensayo y error, y basados en condiciones socioeducativas diversas ¿Qué aprendizaje se puede extraer de este inédito proceso educativo? Parte de esta respuesta está en el profesorado que ha gestionado esta educación de emergencia. En este sentido, este estudio busca explorar y caracterizar las debilidades, amenazas, fortalezas y oportunidades (DAFO) con que el docente peruano de secundaria concibe la digitalización en el marco de la pandemia por Covid-19. El estudio recurre a un enfoque de investigación cualitativo a parti…
Design Archives: Sustainable Solutions for Young Designers in Valencia, Spain
2023
Design education is practical and theoretical; however, it does not usually include the study of cultural heritage. Nonetheless, relations with academia have been strong since the 18th century, when the need to educate designers spread across the continent to improve design and make it competitive in the market. In this paper, we recover that spirit and act as mediators between heritage and young people to create links and preserve cultural heritage. A case study was conducted at the Public Valencian Design School with 31 product design students. The methodology applied was based on iterative processes that allowed students to discover design and silk heritage when they proposed innovative …
Gender Bias in choosing STEM studies
2022
The gender bias in STEM exists, and this work intends to make this reality visible. The principal objectives of the study are to reduce the gender gap in STEM studies and learn about experiences lived around the STEM field reported by women. For this, a qualitative research method has been created in the form of an interview, which helps us answer the questions raised from the life stories told by the fourteen girls and women interviewed, all of them belonging to different age ranges, to be able to observe and analyze gender bias when choosing STEM studies. The data resulting from the research are the least bleak in the framework of the development of gender equality. A minimum change could…
Start-Up of Chitosan-Assisted Anaerobic Sludge Bed Reactors Treating Light Oxygenated Solvents under Intermittent Operation
2021
Quality of the granular sludge developed during the start-up of anaerobic up-flow sludge bed reactors is of crucial importance to ensure the process feasibility of treating industrial wastewater such as those containing solvents. In this study, the microbial granule formation from suspended-growth biomass was investigated in two chitosan-assisted reactors. These reactors operated mimicking industrial sites working with night closures treating a mixture of ethanol, ethyl acetate, and 1-ethoxy-2-propanol. Each reactor operated under different hydrodynamic regimes typical from UASB (R1: <
Building Trust on Zoom: A Workflow for Language Documentation via Videoconferencing Software
2022
The COVID-19 pandemic affected the capacity to conduct linguistic fieldwork in person. For many fieldworkers, this meant they needed to adapt, and do so urgently. This paper discusses a language documentation workflow based entirely on the online conferencing software Zoom, in which a linguist, external to the community, establishes a new project together with a native-speaker community member. The paper describes how such a working relationship can be built online, and accounts for all the steps of the authors' Zoom-mediated workflow in detail allowing for their replication. It also offers a critical appraisal of this workflow from the perspectives of both the native speaker and the resear…
