Interpretazioni figurative per leggere e rappresentare le forme urbane di Venezia Figurative interpretations to read and represent the urban forms of Venice

Il contributo affronta il tema della Rappresentazione della città, intesa come strumento capace non solo di definire gli aspetti quantitativi che ne caratterizzano la fisicità e le qualità morfometriche, ma anche in grado di intercettare le qualità sfuggenti e invisibili che le città producono e che sono diffi- cilmente rappresentabili. Il disegno della città contemporanea racconta infatti la storia di un continuo andare dal generale verso il dettaglio, dalle costruzioni di visioni d’as...

Analytical modeling of the detection capability in ultra-low power wireless sensor networks

This paper addresses the problem of target detection with unattended Wireless Sensor Networks (WSNs) used for monitoring areas of interest. As battery energy depletion is very critical, especially in long-lasting surveillance scenarios, an attractive approach consists in making the wireless nodes switch on and off their sensing module according to given duty cycles. This operation has an impact on the network lifetime and the probability of target missed detection (Pmd), which mainly depends ...

Leak Detection and Classification in Pharmaceutical Freeze-Dryers: An Identification-Based Approach

Freeze-drying is a standard procedure in pharmaceutical industry, used to stabilize, store and increase the shelf life of drug products. In this process, the product has to be brought to a very low pressure and the lyophilization chamber has to be perfectly sealed. Even small external leaks can contaminate the entire drug batch. Since a single batch may contain thousands of product vials, freeze-dryer leakages are one of the most critical problems of the entire production chain of lyophilized...

UWB TDoA-based Positioning Using a Single Hotspot with Multiple Anchors

In this paper, we address target positioning in scenarios where the reference nodes, denoted as anchors, are not distributed at the perimeter of the area where the target is, but are concentrated in a very small region and target is outside this region. This scenario may be meaningful in smart building applications, where anchor nodes cannot be distributed and cabled in the monitored area. On the other hand, anchors may be installed on a single hotspot to be placed at the center of the enviro...

Thimble regularisation of YM fields: crunching a hard problem

Thimble regularisation of Yang Mills theories is still to a very large extent terra incognita. We discuss a couple of topics related to this big issue. 2d YM theories are in principle good candidates as a working ground. An analytic solution is known, for which one can switch from a solution in terms of a sum over characters to a form which is a sum over critical points. We would be interested in an explicit realisation of this mechanism in the lattice regularisation, which is actually quite ...
