La formazione dei formatori e la Danzamovimento terapia
2008
La monografia, centrata sulla formazione di futuri formatori (studenti di Scienze della Formazione) e di formatori in servizio (insegnanti), pone l’accento, individuando punti di contatto e possibili collegamenti, sui temi seguenti: - l’interconnessione mente-corpo con riferimenti non solo agli ambiti filosofico e pedagogico, ma anche alle ultime acquisizioni delle neuroscienze - la valenza dei linguaggi artistico espressivi nello sviluppo della personalità creativa e nella formazione dei formatori - la specificità della danzamovimeto-terapia e la sua funzione nell’integrazione del sé e delle competenze espressivo-comunicative, osservative, relazionali Nel testo vengono poi riportate due es…
Capturing gypsum rillenkarren morphometry by a 3D-photo reconstruction (3D-PR) technique
2020
Abstract Rillenkarren are small scale, straight, narrow solution channels that head at the crest of a bare rock slope and are extinguished downslope. In this paper the applicability of 3D-photo reconstruction technique of the rock surface is proposed for capturing the rillenkarren morphometry on gypsum. At first, the measurements are used to assess a relationship between the width/depth ratio and the depth of the rillenkarren. The exponent of this power relationship resulted different from the theoretical value - 0.5, confirming that the cross-section profiles of a rillenkarren can have a shape different from parabolic. The analysis developed for the cross-section area, the perimeter and th…
Wireless HROV Control with Compressed Visual Feedback Using Acoustic and RF Links
2020
AbstractUnderwater cooperative robotics offers the possibility to perform challenging intervention applications, such as recovering archeological objects as within the context of the MERBOTS research project, or grasping, transporting and assembly of big objects, using more than one mobile manipulator, as faced by the TWINBOT project. In order to enhance safety during the intervention, it is reasonable to avoid the umbilical, also giving more mobility to the robots, and enabling a broader set of cooperative movements. Several solutions, based on acoustic, radiofrequency (RF) or Visual Light Communication (VLC) have been proposed for underwater communications in the literature. This paper pr…
DECENTRALIZED SUBSPACE PROJECTION IN LARGE NETWORKS
2018
A great number of applications in wireless sensor networks involve projecting a vector of observations onto a subspace dictated by prior information. Accomplishing such a task in a centralized fashion entails great power consumption, congestion at certain nodes, and suffers from robustness issues. A sensible alternative is to compute such projections in a decentralized fashion. To this end, recent works proposed schemes based on graph filters, which compute projections exactly with a finite number of local exchanges among sensor nodes. However, existing methods to obtain these filters are confined to reduced families of projection matrices or small networks. This paper proposes a method tha…
Evaluation of apical preparations performed with ultrasonic diamond and stainless steel tips at different intensities using a scanning electron micro…
2011
Objective: The objective of our study is to analyse (with the help of scanning electron microscopes) the quality of the dental root surface and the appearance of dental cracks after performing apical preparations using two diffe-rent types of ultrasonic tips. Study design: We used 32 single-rooted teeth that underwent a root canal and apical resection. Afterwards, the teeth were divided into 4 groups of 8 teeth each, with preparations of the apical cavities in the following manner: Group 1: stainless steel ultrasonic tip at 33KHz. Group 2: stainless steel ultrasonic tip at 30KHz. Group 3: diamond ultrasonic tip at 30KHz. Group 4: diamond ultrasonic tip at 33 KHz. The quality of the root sur…
L'architetto a Piazza Armerina. Un progetto per la chiesa di Sant'Anna?
2013
La chiesa di Sant’Anna a Piazza Armerina (dal 1745), di pertinenza delle monache Agostiniane, presenta un singolare prospetto curvilineo realizzato con una cortina di mattoni a vista. L’accentuata conformazione ondulata delle superfici murarie non trova precedenti nei cantieri siciliani, mentre l’uso del laterizio anziché della pietra rafforza ulteriormente l’unicità di questa struttura. Risulta ad oggi sconosciuto l’autore del progetto della chiesa, ma nonostante le lacune documentarie relative alla vicenda ideativa e costruttiva, gli esigui dati pervenuti, la lettura della fabbrica e altri indizi consentono di avviare alcune riflessioni che consentono di attribuire l’ideazione dell’opera …
"I martiri della civiltà greca”: M.I. Rostovtzeff sugli Acta Alexandrinorum
2005
L’articolo analizza l’interpretazione degli Acta Alexandrinorum fornita da M.I. Rostovtzeff, dai quali emergerebbero gli alti ideali della cultura greca e della tradizione di Alessandria di fronte all’imperium Romanum.
Improved centrifugal and hyperfine analysis of ND2H and NH2D and its application to the spectral line survey of L1544
2021
Abstract Quantifying molecular abundances of astrochemical species is a key step towards the understanding of the chemistry occurring in the interstellar medium. This process requires a profound knowledge of the molecular energy levels, including their structure resulting from weak interactions between nuclear spins and the molecular rotation. With the aim of increasing the quality of spectral line catalogs for the singly- and doubly-deuterated ammonia (NH2D and ND2H), we have revised their rotational spectra by observing many hyperfine-resolved lines and more accurate high-frequency transitions. The measurements have been performed in the submillimeter-wave region (265–1565 GHz) using a fr…
Digital demodulation for fast set-up of sensorless PMSM electrical drives based on magnetic anisotropy
2009
This paper presents a demodulation algorithm applied to the sensorless control of permanent magnet synchronous motors (PMSM). The sensorless control technique reported in this paper is based on the injection of high frequency voltages to the stator so that the motor currents contain information on the rotor position. This information is then extracted by an appropriate demodulation technique. The presented demodulation algorithm is based on spectral analysis of the signal produced by the sensorless control technique because this is fully characterized and presents not ambiguous correlation between current harmonic content and rotor position. The most important feature of the demodulation al…
