Architetture del divenire. Innovazioni contemporanee/Emerging Architecture. Contemporary Innovations (presentazione di Giuseppe Pellitteri) - Quadern…
2014
La posizione assunta dall'architettura all'inizio del ventunesimo secolo è ambigua e così la forma degli edifici che ambiscono a convogliare significati. Il processo di radicale trasformazione dell’architettura, avvenuto sin dal primo Novecento, quale conseguenza della graduale sostituzione delle tecniche edilizie tradizionali con le tecniche “moderne”, ha subito un notevole slancio nell'ultimo ventennio, per effetto del crescente mutamento tecnologico. I materiali, le tecniche costruttive e l’innovazione tecnologica hanno condizionato sensibilmente ed irreversibilmente il pensiero architettonico, producendo in questi ultimi anni nuove espressività linguistiche del tutto “insolite” rispetto…
Blokķēžu tehnoloģijas pielietošana augstskolu diplomu autentifikācijas sistēmas izveidē
2021
Šobrīd Latvijā nepastāv vienota diplomu autentifikācijas sistēma, tāpēc gadījumā, ja ir nepieciešams pārliecināties, ka diploms nav viltots – ir jāveic rakstisks iesniegums augstskolai. Darba mērķis ir piedāvāt risinājumu šai problēmai, izstrādājot vienotu diplomu autentifikācijas sistēmas tehnoloģisko risinājumu. Darba teorētiskajā daļā tiek izpētītas datu apstrādes sistēmas, blokķēdes tehnoloģija un platformas, aprakstot to īpašības un darbības principu. Tika noskaidrots, ka blokķēdes tehnoloģija ir atbilstoša darba mērķa sasniegšanai Darba praktiskajā daļā tika apzināti pasaulē esošie blokķēdes tehnoloģijas risinājumi izglītības nozarē. Tika veikta aptauja par Latvijā esošajām augstskolu…
"C'est pas pour nous normalement". La médiation culturelle et les non-publics
2014
International audience; L'article porte sur les non-publics, ces personnes en situation à l'instant t de non-pratique culturelle, de non-contact avec un objet culturel précis. A travers une étude de cas (la réception d'une pièce de théâtre participatif par un groupe de migrants), il montre comment des dispositifs institutionnels de médiation produisent, dans des contextes précis, la distance à la culture que les institutions en charge des politiques culturelles tentent d'abolir.
Segregation in Drying Binary Colloidal Droplets
2019
When a colloidal suspension droplet evaporates from a solid surface, it leaves a characteristic deposit in the contact region. These deposits are common and important for many applications in printing, coating, or washing. By the use of superamphiphobic surfaces as a substrate, the contact area can be reduced so that evaporation is almost radially symmetric. While drying, the droplets maintain a nearly perfect spherical shape. Here, we exploit this phenomenon to fabricate supraparticles from bidisperse colloidal aqueous suspensions. The supraparticles have a core-shell morphology. The outer region is predominantly occupied by small colloids, forming a close-packed crystalline structure. Tow…
Trade-off Performance of Optical Nanoantennas for Solar Energy Harvesting Applications
2019
In this paper, the optimum behaviour of optical nanoantennas, in terms of impedance, directivity, available power, and field enhancement, at a resonance frequency of about 350 THz, will be shown. Optimum configurations are obtained by varying nanoantennas geometry in order to maximize the available power, enhancing the electric field in gap proximity and so the absorptivity. Moreover, the simulation results for aluminum nanoantennas on a three-layers substrate, will be reported, and a trade-off performance comparison among different antennas will be discussed. This study can guide both the engineering and the fabrication of plasmonic nanoantennas.
Di seta et oro. Antichi tessuti nelle chiese di Acireale
2021
This book dedicated to the ancient silk and gold fabrics of the church of Acireale in Sicily, is a text prepared by Fabio Francesco Grippaldi and Maurizio Vitella within the European project H2020 Silknow: Weaving our past into the future (European Union's Horizon 2020 research and innovation program under grant agreement No 769504). It presents a large collection of textile artefacts, largely unpublished, in use in the basilicas of Acireale. The sacred vestments analyzed both in the introductory essays and in the analytical sheets are contextualized in the broad panorama of reference, both national and European, and cover a chronological span that extends from the sixteenth to the twentiet…

Session III - PARAMETRIC MODELLING AND VIDEO MAPPING_INTRODUCTION
2022
Virtual representation, free-form surface modelling techniques and numerical control manufacturing, with their intrinsic dynamic and interactive capabilities, have profoundly expanded and enriched the repertoire of geometric shapes, generating innovative design skills and creative languages. There is no doubt about the opportunities for exploration, contamination, relationships and overlapping of ideas, measurements and information, which the continuous evolution of expeditious, parametric and automatic procedures brings to the use of the many products of the information age. Adopting computation as a form of design is profoundly different from simply using tools geared toward increasing th…
Fabrication of a Silicide Thermoelectric Module Employing Fractional Factorial Design Principles
2021
AbstractThermoelectric modules can be used in waste heat harvesting, sensing, and cooling applications. Here, we report on the fabrication and performance of a four-leg module based on abundant silicide materials. While previously optimized Mg2Si0.3Sn0.675Bi0.025 is used as the n-type leg, we employ a fractional factorial design based on the Taguchi methods mapping out a four-dimensional parameter space among Mnx-εMoεSi1.75−δGeδ higher manganese silicide compositions for the p-type material. The module is assembled using a scalable fabrication process, using a Cu metallization layer and a Pb-based soldering paste. The maximum power output density of 53 μW cm–2 is achieved at a hot-side temp…
