Forensic investigation in aircraft accident with the aid of CT (MSCT), and Magnetic Resonance Imaging (MRI): our experience
2011
The autors report their experience in a case of air disaster in which a Tuninter airlines ATR 72 fallen down into the sea near Capo Gallo coast (Palermo, Italy) with 39 persons on board, resulting in six-teen victims. In the present contribute the authors argued the causes of the death and analysed patternes of injuries sustained by passengers involved in the fatal airplane accident using the conventional autopsy combined with postmortem Multi Slice Computed Tomography (MSCT) examination.
Neck and Shoulder Muscle Activation Among Experienced and Inexperienced Pilots in +Gz Exposure
2017
Background The aim of the present study was to compare differences in electromyography (EMG) activation of the neck and shoulder muscles between groups of inexperienced and experienced pilots during controlled +Gz exposure in a centrifuge. Methods The subjects were volunteer cadets (inexperienced group) and lieutenants (experienced group) undergoing their first centrifuge training. The first group did not have any high performance aircraft (HPA) experience, while the latter one had a 1-yr experience of intense flying of HPA. During the centrifuge run, EMG activity was recorded from the left and right shoulder, neck flexor, and neck extensor muscles. Results The pilots without HPA experience…
A museum system of design/craft for sustainable development in southern Italy
2018
Abstract: In this extended abstract we are going to explain an academic project entitled “THE SYSTEM OF TERRITORIAL DESIGN SYSTEMS. Cultural tourism, craftsmanship and design for the local development of the production enterprises of excellence in Southern Italy and Made in Italy”. It is based on the cooperation among designers and artisans in order to encourage the development of local craft- based production, by creating a REGIONAL MUSEUM SYSTEM OF DESIGN AND APPLIED ARTS in the five regions of Southern Italy. Then, the “SYSTEM OF THE SYSTEMS” is constituted of the five specific museum systems to be created in each region; these systems - especially in Campania and Sicily – can then repre…
The polarimetric and helioseismic imager on solar orbiter
2020
This paper describes the Polarimetric and Helioseismic Imager on the Solar Orbiter mission (SO/PHI), the first magnetograph and helioseismology instrument to observe the Sun from outside the Sun-Earth line. It is the key instrument meant to address the top-level science question: How does the solar dynamo work and drive connections between the Sun and the heliosphere? SO/PHI will also play an important role in answering the other top-level science questions of Solar Orbiter, as well as hosting the potential of a rich return in further science. SO/PHI measures the Zeeman effect and the Doppler shift in the FeI 617.3nm spectral line. To this end, the instrument carries out narrow-band imaging…
Sphinx measurements of the 2009 solar minimum x-ray emission
2012
The SphinX X-ray spectrophotometer on the CORONAS-PHOTON spacecraft measured soft X-ray emission in the 1-15 keV energy range during the deep solar minimum of 2009 with a sensitivity much greater than GOES. Several intervals are identified when the X-ray flux was exceptionally low, and the flux and solar X-ray luminosity are estimated. Spectral fits to the emission at these times give temperatures of 1.7-1.9 MK and emission measures between 4 x 10^47 cm^-3 and 1.1 x 10^48 cm^-3. Comparing SphinX emission with that from the Hinode X-ray Telescope, we deduce that most of the emission is from general coronal structures rather than confined features like bright points. For one of 27 intervals o…
The space age and the origin of space research
2001
The exploration of space is one of the greatest achievements of the twentieth century. In the ideal photo album of this century one could hardly avoid including such pictures as our blue planet seen from space and the human footprint on the Moon’s surface; the close-up images of a comet’s nucleus and the rough landscape of Mars; the floating of astronauts in the black vacuum around a space station and the rings of Saturn photographed from an approaching spacecraft.
Mikromanageroinnin toteuttaminen StarCraft-reaaliaikastrategiapeliin geneettisellä ohjelmoinnilla muodostettujen potentiaalikenttien avulla
2015
Tämä tutkielma selvittää geneettisen ohjelmoinnin sovellettavuutta sellaisten potentiaalikenttien optimointiin, jotka ohjaavat taistelussa reaaliaikastrategiapelien yksiköi- den mikromanagerointia. Tutkimusympäristönä käytetään StarCraft-peliä. Sovellettavassa menetelmässä pelin yksiköiden ohjaaminen potentiaalikentillä tapahtuu siten, että pelin koh- teet: omat yksiköt, vihollisen yksiköt ja pelialueen ulkoreunat, aiheuttavat kukin potentiaa- likentän. Omia yksiköitä liikutetaan siihen suuntaan, jossa kohteiden potentiaalikenttien yh- teisvaikutus on voimakkain. Geneettistä ohjelmointia käytetään optimoimaan eri kohteiden luomien potentiaalikenttien voimakkuutta määrittäviä funktioita. Men…
State Estimation of a Nonlinear Unmanned Aerial Vehicle Model using an Extended Kalman Filter
2008
An Extended Kalman Filter is designed in order to estimate both state variables and wind velocity vector at the same time for a non conventional unmanned aircraft. The proposed observer uses few measurements, obtained by means of either conventional simple air data sensors or a low cost GPS. To cope with the low rate of the GPS with respect to the other sensors, the EKF algorithm has been modified to allow for a dual rate measurement model. State propagation is obtained by means of an accurate six degrees of freedom nonlinear model of the aircraft dynamics. To obtain joint estimation of state and disturbance, wind velocity components are included in the set of the state variables. Both stoc…
Modelling strategic alliances in the wide-body long range aircraft market
2007
Abstract The wide-body long-range aircrafts market is characterized by increasing rivalry between Airbus and Boeing. One of the factors that drive their strategic behaviour is technological. We propose a technology indicator to identify conditions under which the aircraft companies have incentives to join a coalition. For this, we provide measurement of the side-payments necessary to sign a strategic alliance aimed at reducing technological barriers in the market. The results suggest that the existence of side-payments guarantees the stability of a strategic alliance if the gap in the technological level between the firms is high, or competition is through prices. For monopoly, a strategic …
On the nuclear response of the water-cooled Pb-17Li test blanket module for ITER-FEAT
2003
Abstract Within the European Fusion Technology Programme, the Water-Cooled Lithium Lead (WCLL) DEMO breeding blanket line was selected in 1995 as one of the two EU lines to be developed in the next decades, in particular with the aim of manufacturing a Test Blanket Module (TBM) to be tested in ITER-FEAT. The present paper is focused on the study of the WCLL-TBM nuclear response in ITER-FEAT, being specifically oriented to the investigation of the local effects due to the typical C-shaped tubes of the breeder zone, since they could play a pivotal role in the module-relevant thermo–mechanical design. A 3D heterogeneous model of the WCLL-TBM, realistically simulating its new lay out and taking…
