A wearable multimodal interface for exploring urban points of interest

2015

Locating points of interest (POIs) in cities is typically facilitated by visual aids such as paper maps, brochures, and mobile applications. However, these techniques require visual attention, which ideally should be on the surroundings. Non-visual techniques for navigating towards specific POIs typically lack support for free exploration of the city or more detailed guidance. To overcome these issues, we propose a multimodal, wearable system for alerting the user of nearby recommended POIs. The system, built around a tactile glove, provides audio-tactile cues when a new POI is in the vicinity, and more detailed information and guidance if the user expresses interest in this POI. We evaluat…

Quasi-spherical focal spot in two-photon scanning microscopy by three-ring apodization

2005

International audience; We present a beam-shaping technique for two-photon excitation (TPE) fluorescence microscopy. We show that by inserting a properly designed three-ring pupil filter in the illumination beam of the microscope, the effective optical sectioning capacity of such a system improves so that the point spread function gets a quasi-spherical shape. Such an improvement, which allows the acquisition of 3D images with isotropic quality, is obtained at the expense of only a small increase of the overall energy in the axial sidelobes. The performance of this technique is illustrated with a scanning TPE microscopy experiment in which the image of small beads is obtained. We demonstrat…

Blending Collaborative Governance and Dynamic Performance Management to Foster Policy Coordination in Renewable Energy Supply Chains

2020

As the use of renewable energy is growing worldwide, the wind industry is being endorsed as a promising source for clean energy supply. In this context, the strategic management of the supply chain is fundamental to pursue a steady expansion of renewable energy. However, the fragmentation between energy policy design and implementation has been considered as a major cause threatening the effectiveness in managing the supply chain. This problem has been provoked mainly by an unsynchronized and uncoordinated decision-making process that involves public and private institutions. This chapter proposes the adoption of a dynamic performance management approach for enhancing a collaborative govern…

How to support energy policy coordination? Findings from the Brazilian wind industry

2019

Abstract Despite a growing sense of urgency, the deployment of clean technologies has been affected by fragmentation of energy policy design and implementation. In some case, wicked policy issues around renewable energy infrastructure have delayed or even halted the uptake of renewables. To find possible answer to consistent policy design that involves public/private institutions of the electricity sector, the authors propose the adoption of a dynamic performance management approach to support the energy policy coordination.

La prevención de riesgos laborales de tráfico en el cuerpo de la policía municipal

2016

Los accidentes de tráfico son un tipo de accidente laboral presente en gran parte de la población en sus desplazamientos in-itinere, y una importante de causa de muerte. Como parte de la población general, el cuerpo de policía también es víctima de este tipo de accidentes en el desarrollo de sus labores profesionales. A estos accidente laborales debemos sumar los que se producen en el propio desempeño laboral de la policía (en misión), que no puede prescindir del vehículo para la consecución de sus objetivos y el desarrollo de sus tareas. Tomando en cuenta lo anterior, debe decirse que la actividad policial en general y, en específico, la que respecta a la policía Municipal de Madrid, conll…

Una experiencia docente: la introducción del foro en la asignatura de Informática II en Biblioteconomía y Documentación

2010

Este artículo introduce la experiencia docente que se ha llevado a cabo durante el curso académico 2008/09 con la introducción de un foro virtual como herramienta de enseñanza y aprendizaje en la asignatura de Informática II en la Diplomatura de Biblioteconomía y Documentación de la Universitat de València. Para analizar la experiencia se realiza un estudio cuantitativo sobre de la utilización del foro y del tipo de participaciones. Así mismo se valora la opinión de los alumnos sobre el foro como herramienta de trabajo para el aprendizaje.

Urban Air Quality Monitoring Using Vehicular Sensor Networks

2014

The quality of air is a major concern in modern cities as pollutants have been demonstrated to have significant impact on human health. Networks of fixed monitoring stations have been deployed in urban areas to provide authorities with data to define and enforce dynamically policies to reduce pollutants, for instance by issuing traffic regulation measures. However, fixed networks require careful placement of monitoring stations to be effective. Moreover, changes in urban arrangement, activities, or regulations may affect considerably the monitoring model, especially when budget constraints prevent from relocating stations or adding new ones to the network. In this chapter we discuss a diffe…

Water-insoluble β-cyclodextrin–epichlorohydrin polymers for removal of pollutants from aqueous solutions by sorption processes using batch studies: A…

2017

This review is dedicated to Giangiacomo Torri (Istituto di Chimica e Biochimica G. Ronzoni, Milan, Italy) in celebration of his retirement.; International audience; Although water-insoluble cyclodextrin-epichlorohydrin polymers have been known for half a century, these materials are of continued interest to the scientific community, in particular for their interesting environmental applications as sorbents in liquid-solid sorption processes. However, in spite of the abundance of literature and conclusive results obtained at the laboratory scale, interpreting the mechanisms of pollutant elimination remains an interesting source of debate and sometimes of contradiction. This review summarizes…

Can crumb rubber modifier effectively replace the use of polymer- modified bitumen in asphalt mixture?

2021

Laboratory scale mechanical performances on six plant produced mixtures; three semi-dense surface courses and three dense binder courses modified with engineered crumb rubber (ECR) using the dry process are presented. The two types of mixtures produced and investigated fulfilled for the most part, the requirements of the Swiss and/or US standards regarding volumetric properties, water sensitivity and rutting. In advanced testing where no requirements exist, the dense ECR mixtures performed similar to the reference polymer modified mixtures and slightly worse for semi-dense mixtures in high temperature tests, where the binder becomes viscous in the rubber-binder composite and its ability to …
