Dolci simboli

2021

Se risulta impossibile pensare che un cannolo preparato a Palermo sia anche soltanto simile a uno americano o svedese (sic), tutte queste versioni hanno qualcosa in comune. Come nei miti studiati da Lévi-Strauss, tanto più evidente è il tradimento di ogni traduzione quanto più chiara risulta la presenza di una struttura comune, una dimensione profonda a cui non possiamo non imputare questa straordinaria efficacia. Quello che faremo in questo saggio sarà allora utilizzare i dolci siciliani per riflettere sui simboli, su cosa siano ma soprattutto su come si costruiscano, dunque su quel modo simbolico che è stato sempre il convitato di pietra di ogni discorso semiotico, ma anche il punto di pa…

Quantifying Fundamental Vegetation Traits over Europe Using the Sentinel-3 OLCI Catalogue in Google Earth Engine

2022

Thanks to the emergence of cloud-computing platforms and the ability of machine learning methods to solve prediction problems efficiently, this work presents a workflow to automate spatiotemporal mapping of essential vegetation traits from Sentinel-3 (S3) imagery. The traits included leaf chlorophyll content (LCC), leaf area index (LAI), fraction of absorbed photosynthetically active radiation (FAPAR), and fractional vegetation cover (FVC), being fundamental for assessing photosynthetic activity on Earth. The workflow involved Gaussian process regression (GPR) algorithms trained on top-of-atmosphere (TOA) radiance simulations generated by the coupled canopy radiative transfer model (RTM) SC…

An optical classification tool for global lake waters

2017

Shallow and deep lakes receive and recycle organic and inorganic substances from within the confines of these lakes, their watershed and beyond. Hence, a large range in absorption and scattering and extreme differences in optical variability can be found between and within global lakes. This poses a challenge for atmospheric correction and bio-optical algorithms applied to optical remote sensing for water quality monitoring applications. To optimize these applications for the wide variety of lake optical conditions, we adapted a spectral classification scheme based on the concept of optical water types. The optical water types were defined through a cluster analysis of in situ hyperspectral…

Japānas modernās policijas izveide 20.gs., attīstība un ietekme uz mūsdienu Japānas sabiedrību

2017

Bakalaura darba „Japānas modernās policijas izveide 20. gs. , attīstība un ietekme uz mūsdienu Japānas sabiedrību” mērķis bija noskaidrot vai Japānas drošību nodrošina Japānas policija vai Japānas kultūra, sabiedrības audzināšana un tradīcijas. Tāpat darbā tika izpētīts kā mūsdienu Japānas policija veidojās, attīstījās un kā tā ietekmē mūsdienu sabiedrību. Neskatoties uz to, ka Japāna vēsturiski tika ierobežota no pārējās pasaules uz 200 gadiem, Rietumi pārņēma un sāka attīstīt to. Līdz ar to vēsturiskās sistēmas tika atstātas pagātnē. Arī drošības sistēma tika pārskatīta, tāpēc, izpētot visas iespējas, Japānai piemeklēja vistuvāko policijas modeli un ieviesa jaunu sistēmu, kas pasargāja sa…
