Development of microfluidics for sorting of carbon nanotubes
2018
Sorting of carbon nanotubes by their chirality is the current bottleneck in the way to their broad employment based on their exceptional electronic and optical properties. Despite the extensive effort, there is no known method, which would result in really pure chirality ensembles. Previously reported sorting protocols result in enrichment rather than in sorting, alter electronic structure, and suffer from low yield. This is mostly due to the statistical approach, where the nanotubes with mixed chiralities are treated as a set. In this thesis, we propose a new sorting technique based on nanotube-by-nanotube compartmelization, characterization, and sorting in a continuously running droplet-b…
La Lingua dei Segni e le nuove tecnologie. Variazioni e modifiche nella lingua e nella percezione dei segnanti
Il lavoro di ricerca affronta le problematiche relative ai nuovi scenari della comunicazione e della formazione per le persone sorde che fanno uso della Lingua dei Segni Italiana nella società delle nuove tecnologie. La tesi pertanto dà alcuni accenni relativi alla sordità, espone le caratteristiche specifiche della Lingua dei Segni e della scrittura dei sordi, presenta il mondo delle nuove tecnologie sia in ambito comunicativo che formativo, analizzando il panorama del Web 2.0, i social network e i nuovi strumenti della formazione quali le piattaforme didattiche e gli ambienti di e-learning. Il lavoro propone inoltre una riflessione su come il linguaggio e la comunicazione siano cambiate n…
Continuum: A spatiotemporal data model to represent and qualify filiation relationships
2013
International audience; This work introduces an ontology-based spatio-temporal data model to represent entities evolving in space and time. A dynamic phenomenon generates a complex relationship network between the entities involved in the process. At the abstract level, the relationships can be identity or topological filiations. The existence of an identity filiation depends on whether the object changes its identity or not. On the other hand, topological filiations are based exclusively on the spatial component, like in the case of growth, reduction, merging or splitting. When combining identity and topological filiations, six filiation relationships are obtained, forming a second abstrac…
Collaborative Design Rational and Social Creativity in Cultures of Participation
2011
The rise in social computing has facilitated a shift from consumer cultures, focused on producing finished media to be consumed passively, to cultures of participation, where people can access the means to participate actively in personally meaningful problems. These developments represent unique and fundamental opportunities and challenges for rethinking and reinventing design rationale and creativity, as people acclimate to taking part in computer-mediated conversations of issues and their solutions. Grounded in our long-term research exploring these topics, this paper articulates arguments, describes and discusses conceptual frameworks and system developments (in the context of three cas…
A Theoretical and Experimental Investigation of the Spectroscopic Properties of a DNA-Intercalator Salphen-Type ZnIIComplex
2014
The photophysical and DNA-binding properties of the cationic zinc(II) complex of 5-triethylammonium methyl salicylidene ortho-phenylenediiminato (ZnL 2 + ) were investi- gated by a combination of experimental and theoretical methods. DFT calculations were performed on both the ground and the first excited states of ZnL 2 + and on its possi- ble mono- and dioxidation products, both in vacuo and in selected solvents mimicked by the polarizable continuum model. Comparison of the calculated absorption and fluores- cence transitions with the corresponding experimental data led to the conclusion that visible light induces a two-elec- tron photooxidation process located on the phenylenediimi- nato…
Spectroscopie des hexafluorures à nombre impair d'électrons
1995
From a theoretical point of view, a tensorial formalism adapted to the study of molecules or octahedral ions with a half-integer angular momentum has been developed for the first time. We have used here the method of projective representations, more consistent than that of double groups. A complete set of coupling coefficients and formulas, as well as the corresponding computing programs have been elaborated. This has firstly allowed to write a simple model describing the vibronic structure of colored hexafluorides. Then, somme applications of this formalism to the study of rovibronic couplings of XY6 molecules in a fourfold degenerate electronic state have been considered, especially conce…
Un ritratto tra ideale e reale: lo speziale siciliano dal XIV al XVI secolo
2008
Lo studio inquadra le tappe della formazione dello speziale siciliano nel tardomedioevo, con un’attenzione a Capitoli e normativa in uso nell’isola. Viene esaminato nel dettaglio un testamento del 1455 che consente di tracciare lo spaccato familiare e sociale di una famiglia di speziali, ricostruendo beni, attività, qualità di vita.

Spēles ar nepilnīgu informāciju, Texas holdem spēles situāciju modelēšana
2020
Bakalaura darbā pētītas pretinieku modelēšanas metodes, risināti un analizēti spēlētāju stratēģiju veidi. Lai to paveiktu, ir nepieciešams iepazīties ar Spēļu teoriju. Skaidrākam kontekstam tiek aplūkoti spēļu teorijas jēdzieni, spēļu klasifikācija, tuvāk apskatītas spēles ar nepilnīgu informāciju, kas sevī iekļauj arī Beijesa formulas pielietošanu praktiski, kas nepieciešama, lai sekmīgi analizētu spēli. Kā pētāmā spēle izmantota pokera veids – Texas Hold’em, kuras noteikumi un izspēles gaita ir aprakstīta darbā. Spēlei ir izveidotas pretinieku modelēšanas metodes un aprēķinātas uzvaras varbūtības pie noteiktu izspēļu variantiem. Darba noslēgumā ir simulēta 2 spēlētāju spēle, lai praktiski…
Spēles ekstensīvajā formā un to lietojumi
2018
Maģistra darbā ir aprakstītas spēles ekstensīvajā formā un tādi to lietojumu piemēri kā izsoles procesa analizēšana ar atmugurisko indukciju un komunikācijas protokola attēlošana ar spēles koku. Tiek skaidrots arī spēles ar nepilnu informāciju jēdziens un mazāk pētītas saistības starp normālformu un atmuguriskās indukcijas procesu. Maģistra darbs ir domāts kā palīglīdzeklis spēļu teorijas apguvei. Tā pielikumā ir vairāki patstāvīgi veidoti uzdevumi ar atrisinājumiem.
