Soluzioni basate sulla natura per le città portuali. L’approccio “Building with nature” e i limiti di trasferibilità nel contesto italiano

2022

Achieving sustainable development goals in port cities is an increasingly challenging task as the trend is toward their expansion for global competition, thus increasing their impacts on soil, atmosphere, water, and marine and terrestrial ecosystems. The present contribution proposes to explore the Building with Nature approach developed by EcoShape and Deltares in the Dutch context through the comparison of case studies and to highlight some critical issues in its transferability to the Italian context.

Coexistence between IEEE802.15.4 and IEEE802.11 through cross-technology signaling

2017

When different technologies use the same frequency bands in close proximity, the resulting interference typically results in performance degradation. Coexistence methods exist, but these are often technology specific and requiring technology specific interference detection methods. To remove the root cause of the performance degradation, devices should be able to negotiate medium access even when using different technologies. To this end, this paper proposes an architecture that allows crosstechnology medium access by means of a Time Division Multiple Access (TDMA) scheme. In order to achieve cross-technology synchronization, which is required for the TDMA solution, an energy pattern beacon…

Rateless Codes Performance Analysis in Correlated Channel Model for GEO Free Space Optics Downlinks

2012

Settore ING-INF/03 - TelecomunicazioniFree Space Optics (FSO) technologies for satellite communications offer several advantages: wide bandwidth high rate capability immunity to electromagnetic interference and small equipment size. Thus they are suitable for inter-satellite links deep space communications and also for high data rate ground-to-satellite/satellite-to-ground communications. Nevertheless FSO links suffer impairments that cause power signal degradation at the receiver. Scattering and absorption cause power signal attenuations predictable by suitable deterministic models. Optical turbulence causes random irradiance fluctuations which can generate signal fading events and can thereby only be predicted by statistical models. Attenuation and fading events can corrupt FSO links and so it would be recommended to add mitigation error codes on the communication link. FSO channel can be described as an erasure channel: fading events can cause erasure errors. We have identified in rateless codes (RCs) a suitable solution to be employed in FSO links. RCs do not need feedback and they add a redundant coding on the source data that allows the receiver to recover the whole payload despite erasure errors. We implemented two different of rateless codes: Luby Transform (LT) and Raptor. We analyzed their performances on a simulated turbulent GEO FSO downlink (1 Gbps - OOK modulation) at a 106 μm wavelength and for different values of zenith angles. Assuming a plane-wave propagation and employing Hufnagel-Valley we modeled the downlink using: 1) a temporal correlated channel model based on Gamma-Gamma probability distribution and 2) an irradiance covariance function that we converted on a time function using Taylor frozen eddies hypothesis. Our new channel model is able to simulate irradiance fluctuations at different turbulence conditions as it will be shown in the full paper. We will also report performance results of LT and Raptor codes at overhead range varying between 0 and 50% and for different values of source packets.Settore ING-INF/01 - Elettronica

La retroattività della lex mitior nella lettura della giurisprudenza interna e sovranazionale: quali ricadute sul giudicato penale?

2013

Dopo un breve inquadramento sistematico del principio di retroattività della legge penale più favorevole, l’Autrice si sofferma sulle più importanti pronunce sul tema emesse sia dalla Corte costituzionale sia dalle Sezioni Unite, ponendo l’accento sull’incidenza che ha avuto la sentenza “Scoppola” della Corte EDU del 17 settembre 2009, con la quale i Giudici di Strasburgo, mutando il precedente orientamento, hanno affermato che l’art. 7, § 1 della Convenzione non garantisce solamente il principio di non retroattività delle leggi penali più severe, ma impone altresì che, nel caso in cui la legge penale in vigore al momento della commissione del reato e quelle successive adottate prima della …

Pincìpi e naufragi: alcune critiche alla nuova filosofia per il diritto internazionale di Ronald Dworkin e il caso emblematico delle politiche in att…

2022

This contribution critically analyzes Ronald Dworkin's New Philosophy for International Law, by underlying how, his theory of law as interpretation, if transposed to the level of the relations between states, more clearly shows some weaknesses which are mainly connected with the ideality of its fundamental assumptions. After having introduced the fundamental aspects of Dworkin's reflection on international law, the specific contents of the particular principles - of mitigation and salience - that Dworkin places at the basis of his vision of international law are critically analyzed in the face of the prerogatives of contemporary national sovereignty and in relation to the structural limits …
