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.

Evaluation of a chemocapacitive sensor array for the detection of vapor analytes and their mixtures
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
there is a great future in plastics. Personalized approach to the management of hilar cholangiocarcinoma using a 3-d-printed liver model
No full textIn recent years, three-dimensional (3-D) printing technology has become a standard tool that is used in several medical applications such as education, surgical training simulation and planning, and doctor–patient communication. Although liver surgery is ideally complemented by the use of preoperative 3-D-printed models, only a few publications have addressed this topic. We report the case of a 29-year-old Caucasian woman admitted for a Klatskin tumor infiltrating the right portal vein requiring surgery that required complex vascular reconstruction. A life-sized liver model with colorful plastic vessels and realistic looking tumor was created with the aim of planning an optimal surgical approach. According to the 3-D model, we performed a right hepatic trisectionectomy, also removing enbloc the tract of portal vein encased by the tumor and the neoplastic thrombus, followed by a complex vascular reconstruction between the main portal vein and the left portal branch. After 22 months of follow-up, the patient was alive and continuing chemotherapy. The use of the 3-D models in liver surgery helps clarify several useful preoperative issues. The accuracy of the model regarding anatomical findings was high. In the case of complex vascular reconstruction strategies, rational use of 3-D printing technology should be implemented
Capacitive sensor arrays with controllable deposition of the sensing polymer area for VOCs applications: Design and measurement considerations
No full textAbstractInterDigitated Capacitive (IDC) sensor arrays are fabricated with conventional microelectronics-micromachining technologies on quartz substrates. After the IDC 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 performance of the coated IDC array is evaluated in terms of IDC critical dimension, measurement frequency and for two analytes and guidelines for improved sensing performance are proposed. Through careful selection of the polymeric coatings in conjunction with suitable signal processing, discrimination of VOCs is possible
