Questo non è un flashback: frontiere della metalessi
2018
Se Gérard Genette ha contribuito in modo determinante all’annessione della metalessi dagli studi di retorica agli studi di narratologia, è stato ancora più responsabile della marcata deriva cinematografica di quegli stessi studi. Tra tanti suggerimenti ampiamente accolti dagli studiosi, forse alcune provocazioni sono però rimaste nell’ombra: il modo in cui parola e immagine interagiscono nella visualizzazione di racconti e ricordi sono stati riletti come altrettanti giochi metalettici. A poco a poco la metalessi ha finito per espandere i suoi confini, colonizzando i più insospettabili territori della rappresentazione filmica. Non sarà forse il caso di accettarne la sfida per disegnare una p…
Il terzo atto al San Carlo di Napoli nell’ultimo trentennio del Settecento: declino, atrofizzazione, scomparsa
2023
In the last decades of the eighteenth century, the third act of opera seria was gradually reduced in importance and dimensions until it disappeared altogether. The article studies this process in relation to the repertoire of the San Carlo theatre in Naples from 1771 on, with special attention to the intertwining of dramaturgical choices and audience’s behavior. The examination of a large number of librettos and scores makes it possible to fix reliable chronological terms. After an isolated episode in 1780, the adfirmation of the two-act model can be traced back to the 1786-1787 season. The new formula quickly took hold, but three-act operas continued to be performed - with ever decreasing …
Stratēģijas dzīves prasmju attīstīšanai 6. klases angļu valodas stundās
2022
Ilgstošs attālināto mācību process ir atstājis negatīvu ietekmi uz skolēnu prasmēm iesaistīties grupu aktivitātēs, kā arī spēju rast iekšēju motivāciju sadarboties. Psiho-sociālās un savstarpējo attiecību prasmes ir nepieciešamas pusaudžiem, lai pieņemtu pārdomātus lēmumus, komunicētu, un attīstītu spēju tik galā ar problēmām un pārvaldītu savas emocijas. Dzīves prasmju termins apzīmē plašu prasmju kopumu, kas ļauj cilvēkam veiksmīgi tikt galā ar ikdienas prasībām un izaicinājumiem. Laikā, kad pastāv neierobežota informācijas pieejamība, tomēr pastāv aizvien pieaugošas bažas par dzīves prasmēm, kuru apguve ir laikietilpīga un nav pašsaprotama. Skolēniem mēdz pietrūkt tādas dzīves prasmes kā…
A Task Execution Scheme for Dew Computing with State-of-the-Art Smartphones
2021
The computing resources of today’s smartphones are underutilized most of the time. Using these resources could be highly beneficial in edge computing and fog computing contexts, for example, to support urban services for citizens. However, new challenges, especially regarding job scheduling, arise. Smartphones may form ad hoc networks, but individual devices highly differ in computational capabilities and (tolerable) energy usage. We take into account these particularities to validate a task execution scheme that relies on the computing power that clusters of mobile devices could provide. In this paper, we expand the study of several practical heuristics for job scheduling including executi…
Non est pura voluptas. Fisiologia e psicopatologia dell’amplesso in Kafka e Lucrezio
2015
Due brani del romanzo di Kafka Il castello descrivono gli amplessi del protagonista K. con una servetta dell’ostello presso cui egli si trova ospitato. Le due scene e le espressioni usate dallo scrittore per descriverle rimandano a due noti brani del De rerum natura di Lucrezio. Non è facile stabilire se si tratti di una ripresa consapevole (l’“arte allusiva” di Pasquali) o di una semplice reminiscenza, ma la circostanza costituisce in ogni caso la testimonianza di un’affinità spirituale fra i due autori. Two passages from Kafka's novel The Castle describe the embraces of the protagonist K. with a servant of the hostel where he is staying. The two scenes and the expressions used by the writ…
Optimized secure and reliable distributed data storage scheme and performance evaluation in unattended WSNs
2013
Unattended Wireless Sensor Networks (UWSNs), characterized by the absence of real-time communication between sensors and sinks, impose sensors to retain data till the next visit of a mobile sink to off-load their data. In such networks, if a sensor is compromised, data accumulated in the sensor are exposed to attackers. In addition, by holding the secret key of the compromised sensor, attackers can also learn post-compromise data accumulated by the sensor. Furthermore, once sensors stop working due to, for instance, node crash or battery depletion, all the accumulated data will be lost. In this paper, we propose a secure and reliable data distribution scheme that addresses these challenges.…
Concurrent and Distributed Projection through Local Interference for Wireless Sensor Networks
2012
In this paper we use a gossip algorithm to obtain the projection of the observed signal into a subspace of lower dimension. Gossip algorithms allow distributed, fast and efficient computations on a Wireless Sensor Network and they can be properly modified to evaluate the sought projection. By combining computation coding with gossip algorithms we proposed a novel strategy that leads to important saving on convergence time as well as exponentially decreasing energy consumption, as the size of the network increases.
An Efficient, Robust, and Scalable Trust Management Scheme for Unattended Wireless Sensor Networks
2012
Unattended Wireless Sensor Networks (UWSNs) are characterized by long periods of disconnected operation and fixed or irregular intervals between visits by the sink. The absence of an online trusted third party, i.e., an on-site sink, makes existing trust management schemes used in legacy wireless sensor networks not applicable to UWSNs directly. In this paper, we propose a trust management scheme for UWSNs to provide efficient, robust and scalable trust data storage. For trust data storage, we employ geographic hash table to efficiently identify data storage nodes and to significantly reduce storage cost. We demonstrate, through detailed analyses and extensive simulations, that the proposed…
Printed Antennas for Sensor Applications: A Review
2014
With the expansion in number and requirements of modern wireless communications, the technology related to their associated antennas has been continuously improved. Among other options, printed antennas offer excellent features, such as low weight, profile, and cost, while maintaining good performance characteristics. In addition, their straightforward integration with electronics has opened new fields of application such as smart sensing systems. Printed antennas can be used in different parts of a wireless smart sensor as a radio link, sensing element, or even as energy harvester. In this paper, we present a thorough review of recent advances of printed antennas as regards their use in sm…
A hybrid network for maritime on-board communications
2012
Current maritime on-board communications have to be enhanced for safety and security, where ubiquitous technologies can help, together with providing comfort and convenience to the crew and passengers. Employing wireless sensor networks on board is one recent practice of implementing ubiquitous technology for ships, where further study is needed because of the connectivity challenges. Meanwhile, it is important for an on-board communication system to be reliable and flexible for handling emergency situations. In this paper, we propose a solution of employing ubiquitous technology on ships in a way that both connectivity and emergency handling are examined. Two key aspects of this proposal a…
