Studio delle potenzialità delle piattaforme UAV nel campo del rilievo dei Beni Culturali
2013
L'uso di piattaforme aeree senza pilota a bordo (UAV) sta diventando sempre più frequente nel campo del rilievo fotogrammetrico soprattutto grazie ai numerosi vantaggi che tali sistemi presentano rispetto alle classiche riprese di fotogrammetria aerea. Il lavoro condotto descrive i primi risultati ottenuti utilizzando sistemi UAV per il rilievo di Beni Culturali. Lo studio è stato svolto acquisendo alcuni dataset relativi a siti archeologici; tali dataset presentano caratteristiche differenti in relazione ai velivoli utilizzati, alle caratteristiche dei voli ed all’estensione delle aree rilevate. Il lavoro ha permesso di eseguite delle prime valutazioni sulla precisione metrica degli orient…

The structural effect between the output module and chromophore-binding domain is a two-way street via the hairpin extension.
2022
AbstractSignal transduction typically starts with either ligand binding or cofactor activation, eventually affecting biological activities in the cell. In red light-sensing phytochromes, isomerization of the bilin chromophore results in regulation of the activity of diverse output modules. During this process, several structural elements and chemical events influence signal propagation. In our study, we have studied the full-length bacteriophytochrome from Deinococcus radiodurans as well as a previously generated optogenetic tool where the native histidine kinase output module has been replaced with an adenylate cyclase. We show that the composition of the output module influences the stabi…

Hyperspectral UAV-Imagery and photogrammetric canopy height model in estimating forest stand variables
2017
Remote sensing using unmanned aerial vehicle (UAV) -borne sensors is currently a highly interesting approach for the estimation of forest characteristics. 3D remote sensing data from airborne laser scanning or digital stereo photogrammetry enable highly accurate estimation of forest variables related to the volume of growing stock and dimension of the trees, whereas recognition of tree species dominance and proportion of different tree species has been a major complication in remote sensing-based estimation of stand variables. In this study the use of UAV-borne hyperspectral imagery was examined in combination with a high-resolution photogrammetric canopy height model in estimating forest v…
Cartelization process in institutionalized environments: legitimation and political communication
2017
International audience; The main objective of this paper is to analyze cartel party tendencies toward professionalization of communicative institutional processes (Mair, 015).The main role of the media in a audience democracy is indisputable (Manin, 1998). So the media politics are one of the main features of public space. In this way, Political parties have become platforms of placement of their leaders to occupy the largest number of institutional positions. Consequently, this phenomenon has spread as a common practice of our political system. The emergence of partisan elite, which has professionalized itself in high political-institutional positions, has colonized the leadership of publi…
