Casting Robotic end-effectors to reach far objects in space and planetary missions

2006

In this paper we present work aimed at developing a compact robotic device able to reach objects at far distance.The work is based on the idea of casting manipulation, and that allows to deploy an end-effector at large distances from the robot’s base by throwing (casting) it and controlling its ballistic flightusing forces transmitted through a light tether connected to the end-effector itself.

The Industrial Applicability of PEA Space Charge Measurements, for Performance Optimization of HVDC Power Cables

2019

Cable manufacturing industries are constantly trying to improve the electrical performance of power cables. During the years, it was found that one of the most relevant degradation factors influencing the cable lifetime is the presence of space charge in the insulation layer. To detect the accumulated charge, the pulsed electro-acoustic (PEA) method is the most used technique. Despite the wide use of the PEA cell, several issues are still present. In particular, the PEA output signal is strongly disturbed by the acoustic waves reflections within the PEA cell. This causes the distortion of the output signal and therefore the misinterpretation of the charge profiles. This, in turn, may result…

Ultra Reliable Communication in 5G Networks: A Dependability-based Availability Analysis in the Space Domain

2017

Master's thesis Information- and communication technology IKT591 - University of Agder 2017 As our daily life is becoming more dependent on wireless and mobile services, seamless network connectivity is of utmost importance. Wireless networks are expected to handle the growing demand for applications which require higher capacity, without failure. Therein, wireless connectivity is regarded as an essential requirement for a wide range of applications in order to support exible and cost-e ective services. As part of the fth generation (5G) communication paradigm, ultra reliable communication (URC) is envisaged as an important technology pillar for providing anywhere and anytime services to en…

Lo spazio della chiesa tra soglie e declinazioni del vuoto

2015

Gli assunti liturgici derivanti dal Concilio Vaticano II pongono una particolare attenzione sulla spazialità interna dell’edificio cultuale, strettamente relazionata al modo di essere della comunità di fedeli che al suo interno si raduna e da esso è rappresentata. Il progetto di uno spazio liturgico manifesta con chiara evidenza il processo conflittuale che è proprio dell’architettura, un processo che esalta vicendevolmente i termini in gioco motivandone l’intima essenza e dove il rapporto tra la corporeità (con i suoi diversi livelli fisici e simbolici) e la spiritualità dovrebbe definirsi come un riferimento costante rispetto a cui azione, condivisione e partecipazione convergano nella co…

Governance della crisi e importanza del territorio per lo sviluppo regionale

2012

The aim of this paper is a reflection on the role of space in the processes of economic change. Starting in the United States the financial and economic crisis infected Europe after 2007. A wider debate on the current differential role of governments in the U.S. and Europe in addressing the crisis has emerged. The bailout programs in the U.S. have made reference to a unitary and homogeneous reference frame in the presence of a central bank whose broad mandate includes development goals. Europe, instead, has shown a different scenario and the same financial integration project depends on the complex relationship between individuals and the community, national sovereignty and increasingly bin…

On the effects of suitably designed space microstructures in the propagation of waves in time modulated composites

2023

In the one-dimensional case, the amplitude of a pulse that propagates in a homogeneous material whose properties are instantaneously changed in time will undergo an exponential increase due to the interference between the reflected and transmitted pulses generated at each sudden switch. Here, we resolve the issue by designing suitable reciprocal PT-symmetric space-time microstructures so that the interference between the scattered waves is such that the overall amplitude of the wave will be constant in time in each constituent material. Remarkably, for the geometries proposed here, a pulse will propagate with constant amplitude regardless of the impedance between the constituent materials,…

Missing Data in Space-time: Long Gaps Imputation Based On Functional Data Analysis

2017

High dimensional data with spatio-temporal structures are of great interest in many elds of research, but their exhibited complexity leads to practical issues when formulating statistical models. Functional data analysis through smoothing methods is a proper framework for incorporating space-time structures: extending the basic methodology to the multivariate spatio-temporal setting, we refer to Generalized Additive Models for estimating functional data taking the spatial and temporal dependences into account, and to Functional Principal Component Analysis as a classical dimension reduction technique to cope with the high dimensionality and with the number of estimated eects. Since spatial …
