Low-Power Wide-Area Networks in Intelligent Transportation: Review and Opportunities for Smart-Railways
No full textThe aim of this paper is to provide an overview of the state-of-the-art in LPWAN, with a focus on intelligent transportation. IoT and LPWAN technologies appear as very promising for cost-effective remote surveillance, monitoring and control over large geographical areas, by collecting data for several sensing applications (e.g., predictive condition-based maintenance, security early warning and situation awareness, etc.) even in situations where power supply is limited (e.g., solar panels) or absent (e.g., installation on-board freight cars).

La pittura di Cézanne come modello letterario nella poetica di Elio Vittorini
No full textNegli appunti di Elio Vittorini editi postumi con il titolo 'Le due tensioni' (1967) compare il riferimento alle opere di Paul Cézanne. In particolare è dedicato al pittore un coerente insieme di carte in cui si discutono le tecniche rappresentative messe in atto nelle sue tele: tali tecniche sono poste a modello di una nuova ricerca letteraria, di una scrittura narrativa che sappia essere adeguata alle sfide che la cultura e la società della seconda metà del Novecento pongono alla letteratura. La serie di osservazioni intorno all’opera pittorica di Cézanne si affianca ad altre che coinvolgono i testi di Alain Robbe-Grillet, esponente di rilievo dell’école du regard, i quali rappresentano secondo Vittorini un’ipotesi efficace di proposta letteraria. Sul nesso che Vittorini instaura tra l’opera di Cézanne e quella di Robbe-Grillet si intende concentrare l’intervento, mettendo in evidenza un ulteriore tassello della «poetica dello sguardo» nel percorso intellettuale di Vittorini
ADENOCARCINOMA PRIMITIVO INSORTO SU ANSA DIGIUNALE ALLA ROUX
No full textAdenocarcinomas of the small bowel are uncommon lesions. Factors related to this relative resistance are still unknown. Patients are usually seen late in the course of their illness when curative therapy is unlikely. A case of primary adenocarcinoma located in the jejunal loop employed for a Roux-en-Y esophago-jejunostomy is reported in this note

Model-Driven Availability Evaluation of Railway Control Systems
No full textMaintenance of real-world systems is a complex task involving several actors, procedures and technologies. Proper approaches are needed in order to evaluate the impact of different maintenance policies considering cost/benefit factors. To that aim, maintenance models may be used within availability, performability or safety models, the latter developed using formal languages according to the requirements of international standards. In this paper, a model-driven approach is described for the development of formal maintenance and reliability models for the availability evaluation of repairable systems. The approach facilitates the use of formal models which would be otherwise difficult to manage, and provides the basis for automated models construction. Starting from an extension to maintenance aspects of the MARTE-DAM profile for dependability analysis, an automated process based on model-to-model transformations is described. The process is applied to generate a Repairable Fault Trees model from the MARTE-DAM specification of the Radio Block Centre - a modern railway controller
