This is an ensemble of all gyro data acquisition runs for the multicore IFOG (MCIFOG ) and the benchmark PM IFOG (Benchmark IFOG) described in the thesis. The conditions for each individual test data run is given in an excel workbook which tabulates all the relevant conditions for the run. The Readme file gives a further description of all the data files.
All data can be processed via the MATLAB scripts contained in the folder "Gyro Data Analysis".
Process data by updating the "main_dir" variable in the main script, "analyze_gyro_data_v8.m", to match the data folder which is to be processed.
The temperature log for a given run can be processed simultaneously by enabling the "use_thermal_data" option.
Descriptions of processing options and other analysis features is given in the comments of the MATLAB code.
A detailed description of the test configuration for each gyro run is given in the excel files:
"MCIFOG 1 Test Log.xlsx" and "PM Gyro Test Log.xlsx"
Some of the data included in this set is given in the following publication:

Morsi: rave e taranta, un’estetica della corporeità ebbra
Full text linkThe end of the Eighties and till to the beginning of the Nineties were the years of the beginning of Rave culture in Europe and in Italy. The study will analyze the analogies between the origin of the Taranta night and the rave wave who lasted for a few years. Through the categories of tribù (Maffesoli), music, night and TAZ (Bey), the author will accompany the reader into a journey where space and time are not the traditional ones anymore: they are subverted thanks to the repetitivity of a music like Taranta and Techno. Dystopian places and sciamanic attitude to rituals within the praxis of the dance, make Taranta Night and Rave culture in a constant dynamic between past and futur

La Notte della taranta tra ricerca-spettacolo e merce-spettacolo=“La Notte della taranta”: from investigation to perfomance, from music to show-biz
No full text“La Notte della taranta”: from investigation to perfomance, from music to show-biz. The author recreates the most significant moments in the history of the Notte della taranta, one of the most important festivals dedicate to traditional music in Europe. The festival, born in 1998, is organized by Istituto Carpitella; from 2010 this task is carried out by the Foundation La Notte della Taranta. Both institutions also have the purpose to encourage research activities, but almost all the economic resources are used to organize the big show
Novel fibres for next-generation fibre-optic gyroscopes
No full textThe fibre-optic gyroscope (FOG) is one of the most successful optical fibre sensors in history and it has become a keystone technology for high-performance rotation sensing. Its core sensing element is a long optical fibre wound into a coil. Here, sensitivity to rotation scales in proportion with optical path length, and thus much FOG development has been directed toward deploying longer fibres within the same footprint. However, the fibre itself can be a major source of signal errors via Rayleigh backscattering, polarization cross-coupling, environmental effects, and non-linearity – thus, high-performance FOGs require advanced strategies to suppress these limitations in their multi-kilometer long sensing coils. This work explores two exciting fibre technologies which show great potential to address these challenges. The first is multicore optical fibre (MCF), in which multiple, independent optical waveguides (cores) are placed within the same glass cladding. These densely packed cores increase optical length, and thus gyro sensitivity, while preserving the coil geometry. This work details the construction of a fully functional interferometric FOG employing state-of-the-art MCF. This demonstrator uses a 7-core, 154 m long fibre coil, and through acquisition of detailed performance data, we realize the 7X sensitivity improvement conferred by use of MCF. The promise of MCF for FOGs is further highlighted by illustrating novel designs and improvements to existing FOG systems which are afforded by this signal density enhancement. The second fibre technology is hollow core antiresonant fibre (ARF), in which a glass microstructure confines signal light to the central hollow region of the fibre. Ultra-low interaction between light and glass renders the fibre orders of magnitude less sensitive to material and environmental effects. This work highlights several benefits of ARFs for FOGs, including the first-ever measurements of polarization coupling in long, symmetric ARFs. These data show that polarization in ARFs can be 2-3 orders of magnitude purer than the theoretical limit for solid fibres. It is further shown, through use of an advanced resonator FOG testbed, that ARFs are immune to many of the material-related guidance impairments which beleaguer solid core FOGs. Through the analysis and demonstrations presented here we show the great promise that these two novel fibres can offer future FOGs. This is a boon for existing and emerging FOG applications which require high-performance navigation in a compact format – from new concepts in robotics and autonomous vehicles which are beginning to shape our world, to the next-generation of space and submarine applications which will explore new worlds

Leonardo e la taranta
Full text linkEnThe presence of the "tarantula" (taranta) in Leonardo da Vinci's writings, more precisely in his "bestiary", was noted for the first time by Ernesto De Martino in "La terra del rimorso" (1961). However, the anthropologist had not been able to identify the source of the quotation, which is fully reproduced in this essay. After framing the phenomenon in the culture of the time, with appropriate references to De Ardoynis, Ponzetti and Antonio De Ferrariis Galateo, the author focuses on Leon Battista Alberti, anticipator of Leonardo and possible secondary source his as being informed on the subject. The inclusion of two 20th century classics, Italo Calvino and Thomas Mann, draws its justification on the literary level as a key to the complexity of Leonardo's thought.ItLa presenza della taranta negli scritti di Leonardo da Vinci, più esattamente nel suo "bestiario", fu notata per la prima volta da Ernesto De Martino ne "La terra del rimorso" (1961). L'antropologo però non aveva potuto individuare la fonte della citazione, che in questo saggio viene riproposta integralmente. Dopo aver inquadrato il fenomeno nella cultura del tempo, con opportuni riferimenti a De Ardoynis, Ponzetti e Antonio De Ferrariis Galateo, l'autore si sofferma su Leon Battista Alberti, anticipatore di Leonardo e sua possibile fonte secondaria in quanto informato sull'argomento.
