Sea level trends and variability in the Adriatic Sea and around Venice
Vignudelli S, De Biasio F, Scozzari A, Zecchetto S, Papa A
A preliminary analysis of sea level (SL) changes around Venice from three tide gauges (TGs) (one off-shore: AAPTF, one at the coast: DSL, and one inside the lagoon: PS) to characterize the variability during 1993-2015 and relative SL trends, is provided. As no global positioning system (GPS) data covering the same period was available to the authors for the three tide gauges, the analysis is restricted to changes relative to the land. Monthly SL means from the European Space Agency (ESA) Sea Level Climate Change Initiative (CCI) altimeter-derived product are also used. A comparison between the monthly mean time series of CCI and AAPTF has been performed using the nearest CCI grid point to the location of AAPTF: the centered Root Mean Square Difference (cRMSD: the root mean square difference of the two series with the respective means removed) resulted 6.33 cm, while the Pearson's linear correlation reached 0.75. Much higher agreement was found, as expected, between the monthly mean records of AAPTF and PS TGs: the cRMSD was 1.03 cm, and the linear correlation 0.99. We obtained 6.65 mm year1 at AAPTF over the Satellite Altimetry (SA) era (1993-2015). A smaller trend has been found here from altimetry (4.25 mm year1). The differences might be explained in terms of Vertical Land Motion (VLM) which was not accounted for in the TGs time series, to the different processing of TGs and altimeter data (in the altimeter signal the Dynamic Atmospheric Correction is removed), and/or uncertainties in this area due to the current CCI product that is based on open ocean altimetry. In general, the altimetry trends derived from CCI are spatially higher in the Adriatic Sea than Global Mean Sea Level (GMSL) in most of the region, with greater values than average in Venice. Reprocessing of along-track altimeter data sets with consistent coastal processing for all missions is expected to enhance SL accuracy and with a better refining of raw trends. The SA era is too short to delineate or discuss an affordable climatology, as decadal SL variations cannot be accounted for by such a short time series, nonetheless the rates calculated in this study are fruitfully compared each other and with those derived by SA.Source: INTERNATIONAL ASSOCIATION OF GEODESY SYMPOSIA, pp. 1-65

La variation des visiteurs de montagne ces dernières années modifie de manière significative les problèmes du territoire montagnard: si d'une part le nombre de visiteurs temporaires augmente (touristes, travailleurs, etc ...), d'autre part le nombre d'habitants diminue. Le premier, parmi les divers, élève la maladie aiguë de haute montagne (MAM) à un problème de santé publique non négligeable; le second conduit à une gestion moindre du territoire générant des problèmes directs et indirects, parmi ceux-ci, également favorisés par le réchauffement climatique, ainsi que la prolifération des tiques. Cette recherche a spécifiquement examiné les facteurs de risque individuels liés au mode de vie et à la MAM.

Design and validation of the readable device: a single-cell electromagnetic refreshable Braille display
Bettelani Gc, Averta G, Catalano Mg, Leporini B, Bianchi M
Blindness represents one of the major disabling societal causes, impacting the life of visually impaired people and their families. Regarding the access to written information, one of the main tools used by blind people is the traditional Braille code. This is the reason why in recent years, there has been a technological effort to develop refreshable Braille devices. These consist of multiple physical dots that dynamically change their configuration to reproduce different sequences of the letters in Braille code. Although promising, these approaches have many drawbacks, which are mainly related to costs, design complexity, portability, and power consumption. Of note, while many solutions have been proposed for multi-cell devices, the investigation of the potentialities of single-cell refreshable systems has received little attention so far. This investigation could offer effective and viable manners to overcome the aforementioned drawbacks, likely fostering widespread adoption of such assistive technologies with end-users. In this paper, we present the design and characterization of a new cost-effective single-cell Electromagnetic Refreshable Braille Display, the Readable system. We report on tests performed with blindfolded and blind expert Braille code readers. Results demonstrate the effectiveness of our device in correctly reproducing alphanumeric content, opening promising perspectives in every-day life applications.Source: IEEE TRANSACTIONS ON HAPTICS, vol. 13 (issue 1), pp. 239-245

Optimized dislocation of mobile sensor networks on large marine environments using voronoi partitions
D'Acunto M, Moroni D, Puntoni A, Salvetti O
The real-time environmental surveillance of large areas requires the ability to dislocate sensor networks. Generally, the probability of the occurrence of a pollution event depends on the burden of possible sources operating in the areas to be monitored. This implies a challenge for devising optimal real-time dislocation of wireless sensor networks. This challenge involves both hardware solutions and algorithms optimizing the displacements of mobile sensor networks in large areas with a vast number of sources of pollutant factors based mainly on diffusion mechanisms. In this paper, we present theoretical and simulated results inherent to a Voronoi partition approach for the optimized dislocation of a set of mobile wireless sensors with circular (radial) sensing power on large areas. The optimal deployment was found to be a variation of the generalized centroidal Voronoi configuration, where the Voronoi configuration is event-driven, and the centroid set of the corresponding generalized Voronoi cells changes as a function of the pollution event. The initial localization of the pollution events is simulated with a Poisson distribution. Our results could improve the possibility of reducing the costs for real-time surveillance of large areas, and other environmental monitoring when wireless sensor networks are involved.Source: JOURNAL OF MARINE SCIENCE AND ENGINEERING, vol. 8 (issue 2)

Factory maintenance application using augmented reality
Coscetti S, Moroni D, Pieri G, Tampucci M
Tissue converting lines represent one of the key plant in the paper production field: with them, paper tissue is converted into its final form for domestic and sanitary usage. One of the key points of the tissue converting lines is the productivity and the possibility to follow conversion process at relativity low cost. Despite the actual lines have yet an high productivity, the study of the state of the art has shown that choke points still exist, caused by inadequate automation. In this paper, we present the preliminary results of a project which aims at removing such obstacle towards complete automation, by introducing a set of innovations based on ICT solutions applied to advanced automation. In detail, advanced computer vision and video analytics methods will be applied to pervasively monitor converting lines and to automatically extract process information in order to self-regulate specific machine and global parameters. Big data analysis methodologies will be also integrated to obtain new knowledge and infer optimal management models which could be used for the predictive maintenance. Augmented reality interfaces are being designed and developed to support converting line monitoring and maintenance, both ordinary and extraordinary. An Artificial Intelligence module provides suggestions and instructions to the operators in order to guarantee production level even in case of unskilled staff. The automation of such processes will improve factory safety, decrease manual interventions and, thus, will increase production line up-time and efficiency.DOI: 10.1145/3378184.3378218

Monitoring ancient buildings: real deployment of an IoT system enhanced by UAVs and virtual reality
Bacco F. M., Barsocchi P., Cassarà P., Germanese D., Gotta A., Leone G. R., Moroni D., Pascali M. A., Tampucci M.
The historical buildings of a nation are the tangible signs of its history and culture. Their preservation deserves considerable attention, being of primary importance from a historical, cultural, and economic point of view. Having a scalable and reliable monitoring system plays an important role in the Structural Health Monitoring (SHM): therefore, this paper proposes an Internet Of Things (IoT) architecture for a remote monitoring system that is able to integrate, through the Virtual Reality (VR) paradigm, the environmental and mechanical data acquired by a wireless sensor network set on three ancient buildings with the images and context information acquired by an Unmanned Aerial Vehicle (UAV). Moreover, the information provided by the UAV allows to promptly inspect the critical structural damage, such as the patterns of cracks in the structural components of the building being monitored. Our approach opens new scenarios to support SHM activities, because an operator can interact with real-time data retrieved from a Wireless Sensor Network (WSN) by means of the VR environment.Source: IEEE ACCESS

Deep learning for time series
Martinelli M
The main purpose of this technical report is only to introduce to the use of the "pandas" open source, BSD-licensed library1. and of the TensorFlow framework2 fot forecasting time series. The use case chosen is of great relevance, the application is a mere experiment that a posteriori can find a confirmation: data is used for SARS Cov-2 spread forecasting too, it is fair to reiterate that these are only a kind of study notes. This is not an epidemiological study, moreover forecasts are strongly based on the numbero suspected cases, that is most probably higher than reported, of course on the behaviour of citizens, and on other unpredicatble factors. Moreover a recent study3 supposes that most infective people are asympthomatic.

High altitude mountain telemedicine
Martinelli M, Bastiani L, Moroni D, Mrakicsposta S, Giardini G, Pratali L
Introduction: An innovative teleconsultation platform has been designed, developed and validated between Summer 2017 and Winter 2018, in five mountain huts and in three remote outpatients clinical centres of the Italian region Valle d'Aosta of the Mont Blanc massif area. Methods: An ad hoc video- conference system was developed within the framework of the e-Rés@mont (Interreg Alcotra) European project, to tackle general health problems and high altitude diseases (such as acute mountain sickness, high-altitude pulmonary and cerebral edema). The system allows contacting physicians at the main hospital in Aosta to perform a specific diagnosis and to give specific advice and therapy to the patients in an extreme environment out-hospital setting. At an altitude between 1500 and 3500 meters, five trained nurses performed clinical evaluations (anamnesis, blood pressure, heart rate, oxygen saturation), electrocardiographic and echography monitoring on both tourists and residents as necessary; all the collected data were sent to the physicians in Aosta. Results: A total of 702 teleconsultation cases were performed: 333 dismissed (47%), 356 observed (51%), 13 immediate interventions (2%). In 30 cases the physicians decided there was no need for helicopter and ambulance rescue intervention and hospital admissions. The main physiological measures, the classified pathologies, the severe cases, and cost savings are described. Discussion: The e-Rés@mont teleconsultation platform has been discussed in terms of treated cases, feasibility, proactivity in reducing complexities, direct and indirect advantages, and diagnostics help; moreover general and specific pros and cons have been debated, and future steps have been exposed.Source: JOURNAL OF TELEMEDICINE AND TELECARE, vol. 28 (issue 2), pp. 135-145

Uso di tecniche di sparse independent component analysis per l'estrazione di regioni di interesse in opere pittoriche e grafiche
Salerno E
In questa nota si mostra come, in certe applicazioni legate alle tecnologie dell'informazione per lo studio del patrimonio culturale, possano essere applicati metodi di separazione cieca delle componenti basati sulla sparsità e non sull'indipendenza statistica. Nelle applicazioni in cui sia necessario estrarre da immagini di opere pittoriche o manoscritti delle regioni di interesse isolate spazialmente, le condizioni di sparsità sono teoricamente verificate già nello spazio delle immagini, e non occorre passare a uno spazio trasformato per poterle imporre alla soluzione del problema. Da due algoritmi recentemente proposti in letteratura, sono stati derivati e sperimentati i corrispondenti operanti direttamente nello spazio delle immagini. Uno di essi impone solo il requisito di sparsità, mentre l'altro aggiunge anche un vincolo di incorrelazione. Gli esperimenti sono condotti su due immagini reali, una relativa a un dipinto acquisito nel visibile e nell'infrarosso e una a un manoscritto acquisito su entrambe le facce nelle tre bande rossa, verde e blu dello spettro visibile.

Integration of analysis of the hierarchical process and dempster-shafer theory for cooperative evaluation tasks
Salerno E
This note gives some details on the application of Saaty's Analysis of Hierarchy Process and the Dempster-Shafer theory for an evaluation problem that embeds a multicriterion decision and an expert judgement on a number of value indicators. These two tasks are assumed to be entitled to two groups of experts. The judgement matrices issued by the first group are geometrically averaged and the related criteria are prioritized by the analysis of hierarchy process. Then, the judgements from the second group of experts are translated into a fuzzy language and fused through the Dempster-Shafer theory. Finally, the masses resulting from this process are propagated up the hierarchy using the previously computed priorities.

Designing assistive technology for getting more independence for blind people when performing everyday tasks: an auditory-based tool as a case study
Leporini B, Rosellini M, Forgione N
Everyday activities and tasks should in theory be easily carried by everyone, including the blind. Information and Communication Technology (ICT) has been widely used for supporting solutions. However, the solutions can be problematic for the visually impaired since familiarity with digital devices is often required. Or, indeed the procedure can be perceived as fiddly or impractical particularly for repetitive tasks due to the number/type of steps required to complete the task. This paper introduces a simple audio-based tool aimed at supporting visually-impaired people in the seemingly simple activity of checking whether the light in a room is on or off. It is an example of potential low tech devices that can be designed without the need for specific skills or knowledge by the user, and that functions in a practical way. In this context, we discuss the main issues and considerations for totally blind users in identifying whether a light is switched on. The proposed prototype is based on a simple circuit and a form of auditory feedback which informs the user whether they are switching on or off the light. Two prototypes have been designed and built for two different kinds of installation. For the subsequent second prototype, three different versions are proposed to provide a blind person with further support in easily identifying the light status at home. The new design includes enhanced auditory feedback and modifications to the dimensions. The evaluation conducted by involving various groups of end-users revealed the usefulness of the proposed tool. In addition, a survey conducted with 100 visually-impaired people reported the limitations and difficulties encountered by the blind in using existing devices. Moreover, the study revealed the interest from 94% of the participants for a potential (new) basic tool integrable with the existing lighting system. This study gives a contribution in the ambient intelligence field by (1) showing how an auditory-based tool can be used to support totally blind people to check the lights in an autonomous and relatively simple way; (2) proposing an idea that can be exploited in other application cases that use light feedback; and (3) proposing seven potential recommendations for designing assistive technology tools and common everyday devices, based on information gathered from the online survey.Source: JOURNAL OF AMBIENT INTELLIGENCE & HUMANIZED COMPUTING (PRINT), vol. 11, pp. 6107-6123

The proposed prototype is based on a simple circuit and a form of auditory feedback which informs the user whether they are switching on or off the light. Two prototypes have been designed and built for two different kinds of installation. For the subsequent second prototype, three different versions are proposed to provide a blind person with further support in easily identifying the light status at home. The new design includes enhanced auditory feedback and modifications to the dimensions. The evaluation conducted by involving various groups of end-users revealed the usefulness of the proposed tool. In addition, a survey conducted with 100 visually-impaired people reported the limitations and difficulties encountered by the blind in using existing devices. Moreover, the study revealed the interest from 94% of the participants for a potential (new) basic tool integrable with the existing lighting system. This study gives a contribution in the ambient intelligence field by (1) showing how an auditory-based tool can be used to support totally blind people to check the lights in an autonomous and relatively simple way; (2) proposing an idea that can be exploited in other application cases that use light feedback; and (3) proposing seven potential recommendations for designing assistive technology tools and common everyday devices, based on information gathered from the online survey.Source: JOURNAL OF AMBIENT INTELLIGENCE & HUMANIZED COMPUTING (PRINT), vol. 11, pp. 6107-6123

Assessment and Diagnostic Accuracy Evaluation of the Reflux Symptom Index (RSI) Scale: Psychometric Properties using Optimal Scaling Techniques
Nacci A, Bastiani L, Barillari Mr, Lechien Jr, Martinelli M, De Bortoli N, Berrettini S, Fattori B
Objectives: To investigate the psychometric properties of the reflux symptom index (RSI) as short screening approach for the diagnostic of laryngopharyngeal reflux (LPR) in patients with confirmed diagnosed regarding the 24-hour multichannel intraluminal impedance-pH monitoring (MII-pH).Methods: From January 2017 to December 2018, 56 patients with LPR symptoms and 71 healthy individuals (control group) were prospectively enrolled. The LPR diagnosis was confirmed through MII-pH results. All subjects (n = 127) fulfilled RSI and the Reflux Finding Score (RFS) was performed through flexible fiberoptic endoscopy. The sensitivity and the specificity of RSI was assessed by ROC (Receiver Operating Characteristic) analysis.Results: A total of 15 LPR patients (26.8%) of the clinical group met MII-pH diagnostic criteria. Among subjects classified as positive for MII- pH diagnoses, RSI and RFS mean scores were respectively 20 (SD ± 10.5) and 7.1 (SD ± 2.5), values not significantly different compared to the negative MII-pH group. The metric analysis of the items led to the realization of a binary recoding of the score. Both versions had similar psychometric properties, ? was 0.840 for RSI original version and 0.836 for RSI binary version. High and comparable area under curve (AUC) values indicate a good ability of both scales to discriminate between individuals with and without LPR pathology diagnosis. Based on balanced sensitivity and specificity, the optimal cut-off scores for LPR pathology were >= 5 for RSI binary version and >= 15 for RSI original version. Both version overestimated LPR prevalence. The original version had more sensitivity and the RSI Binary version had more specificity.Conclusions: It would be necessary to think about modifying the original RSI in order to improve its sensitivity and specificity (RSI binary version, adding or changing some items), or to introduce new scores in order to better frame the probably affected of LPR patient.Source: ANNALS OF OTOLOGY RHINOLOGY AND LARYNGOLOGY

Thermal vulnerability detection in integrated electronic and photonic circuits using infrared thermography
Hussain B, Jalil B, Pascali Ma, Imran M, Serafino G, Moroni D, Ghelfi P
Failure prediction of any electrical/optical component is crucial for estimating its operating life. Using high temperature operating life (HTOL) tests, it is possible to model the failure mechanisms for integrated circuits. Conventional HTOL standards are not suitable for operating life prediction of photonic components owing to their functional dependence on the thermo-optic effect. This work presents an infrared (IR)-assisted thermal vulnerability detection technique suitable for photonic as well as electronic components. By accurately mapping the thermal profile of an integrated circuit under a stress condition, it is possible to precisely locate the heat center for predicting the long-term operational failures within the device under test. For the first time, the reliability testing is extended to a fully functional microwave photonic system using conventional IR thermography. By applying image fusion using affine transformation on multimodal acquisition, it was demonstrated that by comparing the IR profile and GDSII layout, it is possible to accurately locate the heat centers along with spatial information on the type of component. Multiple IR profiles of optical as well as electrical components/circuits were acquired and mapped onto the layout files. In order to ascertain the degree of effectiveness of the proposed technique, IR profiles of complementary metal-oxide semiconductor RF and digital circuits were also analyzed. The presented technique offers a reliable automated identification of heat spots within a circuit/system.Source: APPLIED OPTICS (2004, ONLINE), vol. 59 (issue 17), pp. E97-E106
