RoadMic: Road Surface Monitoring Using Vehicular Sensor Networks with Microphones

2010

Road surface analysis including pothole reports is an important problem for road maintainers and drivers. In this paper we propose a methodology for pothole detection using mobile vehicles equipped with off the shelf microphone and global positioning devices attached to an on-board computer. The approach is generic enough to be extended for other kind of event detection using different sensors as well. The vehicles are driving on public streets and measuring pothole induced sound signals. Our approach was tested and evaluated by real world experiments in a road segment for which we had established the ground truth beforehand. The results show pothole detection with high accuracy despite the…

Low Latency Ambient Backscatter Communications with Deep Q-Learning for Beyond 5G Applications

2020

Low latency is a critical requirement of beyond 5G services. Previously, the aspect of latency has been extensively analyzed in conventional and modern wireless networks. With the rapidly growing research interest in wireless-powered ambient backscatter communications, it has become ever more important to meet the delay constraints, while maximizing the achievable data rate. Therefore, to address the issue of latency in backscatter networks, this paper provides a deep Q-learning based framework for delay constrained ambient backscatter networks. To do so, a Q-learning model for ambient backscatter scenario has been developed. In addition, an algorithm has been proposed that employ deep neur…

Culture and Real-time Polymerase Chain reaction sensitivity in the diagnosis of invasive meningococcal disease: Does culture miss less severe cases?

2019

BackgroundInvasive meningococcal disease (IMD) is a highly lethal disease. Diagnosis is commonly performed by culture or Realtime-PCR (qPCR).AimsOur aim was to evaluate, retrospectively, whether culture positivity correlates with higher bacterial load and fatal outcome. Our secondary aim was to compare culture and qPCR sensitivity.MethodsThe National Register for Molecular Surveillance was used as data source. Cycle threshold (CT), known to be inversely correlated with bacterial load, was used to compare bacterial load in different samples.ResultsThree-hundred-thirteen patients were found positive for Neisseria meningitidis by qPCR, or culture, or both; 41 died (case fatality rate 13.1%); 1…

This institution in charge of governing the Royal Heritage had to face difficult situations and create new solutions to the problems posed by the revolted. I…

Tensions and expression in Milos Forman’s American films

2012

Milos Forman’s American films require a plural outlook. The director has always been drawn to stories of conflicts that are essential, according to him, to study human passion. This tension, thematic as well as esthetic, allows him to show the smallest mechanisms that lead to oppression in European and American stories, providing the viewer with a lesson of anatomy that pinpoints the most invisible magnetic forces leading to power. This course is accompanied by a journey to individualism, through forces involved in the identification with attractive though realistic characters, through the rediscovery of individual freedom within primitive or regressive worlds, insisting on the necessity of…

Effects of mixed reality head-mounted glasses during 90 minutes of mental and manual tasks on cognitive and physiological functions

2018

Background We evaluated the effects of a mixed reality (MR) head-mounted deviceon some cognitiveand physiological functions during 90 min tasks in an attempt to determine their safety for workers. Methods A total of 12 volunteers performed 90-min intellectual and manual tasks with and without MR glasses. Balance, Stroop, and memory tests were conducted before, during and after these tasks. Heart rate and electromyographic activity of some muscles were recorded. A survey was used to determine subjective fatigue, pain, or discomfort. Results Balance, heart rate, rate of perceived exertion, memory, and attention were unaffected by wearing MR glasses. Electromyographic activity increased with …

A new historical perspective regarding the baptismal font of the cathedral of Monreale (Sicily): the identification of a reused Roman labrum by an an…

2017

The Cathedral of Monreale (not far from the city of Palermo) is one of the most famous monuments of the Arab-Norman period in Sicily recently added to the World Heritage list by UNESCO. It is well known above all for its structure and the magnificence mosaic decorations inside. In the church it is also conserved a Baptismal Font made of coloured limestone and dated back to the first decade of the 17th century. The present study deals with this valuable object with the aim of obtaining information about the nature and provenance of the coloured limestone constituting the basin. Laboratory analyses were thus carried out on representative stone samples by means of polarized light microscopy as…

Dasymetric distribution of votes in a dense city

2017

[EN] A large proportion of electoral analyses using geography are performed on a small area basis, such as polling units. Unfortunately, polling units are frequently redrawn, provoking breaks in their data series. Previous electoral results play a key role in many analyses. They are used by political party workers and journalists to present quick assessments of outcomes, by political scientists and electoral geographers to perform detailed scrutinizes and by pollsters and forecasters to anticipate electoral results. In this paper, we study to what extent more complex geographical approaches (based on a proper location of electors on the territory using dasymetric techniques) are of value in…

Iugalia vetustissima. Argenti, avori e smalti nel Tesoro della Chiesa Madre (XIV-XV secolo)

2016

Nel contributo si approfondisce lo studio di oggetti liturgici già noti (due calici di argentieri e smaltisti siciliani toscaneggianti, di fine XIV-inizi XV secolo il primo, del 1429 il secondo; un reliquiario di argentiere genovese e maestranze veneziane della prima metà del XV secolo), mentre si portano per la prima volta all'attenzione degli studiosi del settore altri tre manufatti: una croce da tavolo, già stauroteca, in argento, opera siciliana della metà del XV secolo, su cui si innestano due statuette protogotiche a tutto tondo di Dolenti in avorio o osso, forse dovute a maestranza iberica di fine XIII-inizi XIV secolo, ed un Crocifisso metallico su croce lignea del XVIII secolo; una…
