Keynote: Musical experience: An educational entitlement in inclusive contexts. The role of teachers/educators/social workers in promoting relational health
No full textKey note speaker. The title of my communication is the title of the higher education course organized at the University of Bologna, where I work as an associate professor in Musicology. The course was organized in the framework of the European projects LINK and STALWARTS, two European projects which addressed the risks of young people in Europe who are currently disadvantaged in formal education. The aim of STALWARTS was to implement university modules in the 5 university partners of the project (Bergen, Bologna, Oporto, Tallinn, West of England), for teachers / educators / education operators, based on participatory action research and on the idea that musical experience is an entitlement in inclusive contexts. I will present the theoretical framework, the description of the module and the professional profile implemented at the University of Bologna
The first international workshop on wirelessly powered systems and networks (WPSN): Message from the WPSN 2019 Workshop Chairs
No full textIt is a great pleasure to welcome you to the first edition of the International Workshop on Wirelessly
Powered Systems and Networks (WPSN), which is organized this year in conjunction with DCOSS
2019 in Santorini, Greece.
Wireless Power Transfer (WPT) is the driving technology that will enable the next generation of the
distributed sensor systems, including battery-less sensors, passive RFID, as well as IoT, 5G and
M2M solutions. Distributed WPT-enabled devices can be powered by harvesting energy from the
surroundings (for example electromagnetic energy), leading to a novel communication systems
networks paradigm, the Wirelessly Powered Systems and Networks. The WPSN workshop aims at
providing an interdisciplinary reference forum focusing on the use of WPT as an enabler for
improving the efficiency of current distributed communication systems and networks.
In this context, WPSN 2019 brings together researchers from academia and industry to discuss
technical challenges and novel ideas regarding wirelessly powered systems and networks,
especially focusing on user cooperation, energy optimization and communication networks. The
answer to the call for papers was encouraging for this first edition of the workshop. The members of
the Technical Program Committee identified 6 high quality papers for presentation in the workshop
technical sessions.
The organization of this workshop has been possible due to the hard work and dedication of many
colleagues. Special thanks are due to the members of the Technical Program Committee and to all
external referees for their invaluable contributions in completing the review process. We are also
very grateful to all the authors for submitting their fine work to our workshop.
We sincerely hope that you will enjoy the program
Must fermentation progress monitoring by polymer coated capacitive vapour sensor arrays
No full textThe present work deals with the task of monitoring the fermentation progress of grape must with a gas sensor array, without the use of pre-concentrator steps. The sensor array consists of eighrt interdigitated capacitors, coated with different polymeric materials through a well, formatted around the capacitor. The fermentation process of a particular must was duplicated under laboratory conditions and monitored in terms of (a) standard chemical analysis and (b) the response of the sensor array to the headspace of must samples, on a daily basis. PCA analysis revealed that a successful fermentation follows a distinct curve not related to that obtained from a series of equivalent pure ethanol solutions ©2009 IEEE
Characterization of polymer layers for silicon micromachined bilayer chemical sensors using white light interferometry
No full textThe swelling behavior of polymer layers used in silicon micromachined bilayer structures is studied using white light interferometry. The study focuses on poly-hydroxy-ethyl-methacrylate (PHEMA) films and their behavior in terms of film expansion, response time and sensitivity upon exposure to methanol and ethanol vapors. Thin films of PHEMA exhibit higher relative swelling than thicker films, in the presence of methanol, as well as lower diffusion coefficients corresponding to higher response times. © 2005 Published by Elsevier B.V
Polymer/BaTiO3 nanocomposites based chemocapacitive sensors
No full textThe performance of novel capacitive sensors, based on PHEMA-BaTiO3 composite films, is presented. The changes in capacitance response upon exposure to various levels of humidity and ethanol vapor are studied in order to evaluate the effect of incorporated BaTiO3 on the sensitivity-selectivity of the sensors. © 2008 Elsevier B.V.

MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

No full textPolymer coated microfabricated interdigitated electrodes arrays for gas sensing applications
No full textInterDigitated Capacitive (IDC) sensor arrays are fabricated with conventional microelectronics-micromachining technologies on quartz substrates. After fabrication, a polymeric well is patterned around each IDC to precisely define the sensing area and thus deposit coatings of various polymers, by drop casting, in a reproducible and controlled manner. The gas sensing performance of the IDC array is presented for humidity and p-xylene.</jats:p
