Il rilievo con scanner laser del Tempio "G" di Selinunte. Elaborazione delle scansioni e metodo per l'anastilosi virtuale di una colonna
No full textLa possibilità di misurare in un tempo relativamente ridotto le coordinate tridimensionali di un elevato numero di punti rende i sistemi laser scanner particolarmente idonei al rilievo di frammenti erratici; la disponibilità di dati metrici accurati e puntuali, difficilmente ottenibili con le tecniche tradizionali del rilevamento architettonico, rende possibile condurre processi di discretizzazione e razionalizzazione della morfologia dei singoli frammenti.
In questa sede vengono esposte le fasi di lavoro relative all’orientamento relativo ed assoluto delle scansioni laser del Tempio “G” di Selinunte, ed all’anastilosi virtuale dei rocchi di una colonna del fronte nord del tempio; obiettivo dell’anastilosi è la definizione di un metodo che possa essere utilizzato anche per le altre colonne del tempi

PREDICTION OF NUTRITIVE VALUE OF DIETS FOR RABBITS USING AN IN VITRO GAS PRODUCTION TECHNIQUE
No full text[EN] Thirty-one mixed diets for rabbits (DE concentration from 8.44 to 12.29 MJ/kg) were used to predict the digestibility of dry matter (dDM), organic matter (dOM), gross energy (dGE) and digestible energy concentration (DE) from some in vitro gas production parameters, using frozen caecal content from rabbits. Step-wise multiple regression analysis showed that the most significant contribution to the variation expressed by dDM, dOM, dGE and DE arises from crude fibre content (CF). Multiple regression analysis considered more than one independent variable, but it gave only marginally improvements in terms of the accuracy of digestibility prediction. The best equations in terms of R2 and residual standard deviation (RSD) values were: DE (MJ/kg DM) = 0.75 - 0.291 CF - 0.208 ADL + 0.856 GE (R2 = 0.895, RSD 0.279) and dOM (%) = 91.8 - 1.756 CF - 1.283 ADL (R2 = 0.849, RSD 1.655) where CF = crude fibre (%DM), ADL = acid detergent lignin (%DM), GE = gross energy (MJ/kg DM). Dry matter loss (DMl, %) was the in vitro gas production parameter which correlated most closely with dDM, dOM, dGE and DE. The best prediction equations were: DE (MJ/kg DM) = -3.14 + 0.217 DMl + 0.114 B (R2 = 0.734, RSD 0.437) and dOM (%) = - 6.80 + 1.078 DMl + 0.456 B (R2 = 0.691, RSD 2.368), where B is the incubation time (h) at half potential gas. When data of the chemical composition and from fermentation parameters were included concurrently in the model, the most significant contribution to the variation explained of dDM, dOM, dGE and DE still arose from CF. These results suggest that in vitro gas production could be an interesting method of predicting the nutritive value of rabbit diets, but further investigations are required to increase caecal inoculum standardisation and its prediction ability.Stanco, G.; Di Meo, C.; Calabrò, C.; Nizza, A.

MEO SAR: System Concepts and Analysis
No full textExisting microwave remote sensing instruments used for Earth observation face a clear tradeoff between spatial resolution and revisit times at global scales. The typical imaging capabilities of current systems range from daily observations at kilometer-scale resolutions provided by scatterometers to meter-scale resolutions at lower temporal rates (more than ten days) typical of synthetic aperture radars (SARs). A natural way to fill the gap between these two extremes is to use medium-Earth-orbit SAR (MEO-SAR) systems. MEO satellites are deployed at altitudes above the region of low Earth orbits (LEOs), ending at around 2000 km and below the geosynchronous orbits (GEOs) near 35 786 km. MEO SAR shows a clear potential to provide advantages in terms of spatial coverage, downlink visibility, and global temporal revisit times, e.g., providing moderate resolution images (some tens of meters) at daily rates. This article discusses the design tradeoffs of MEO SAR, including sensitivity and orbit selection. The use of these higher orbits opens the door to global coverage in one- to two-day revisit or continental/oceanic coverage with multidaily observations, making MEO SAR very attractive for future scientific missions with specific interferometric and polarimetric capabilities.Mathematical Geodesy and Positionin
