Forma ed emozione

La gradevolezza di un oggetto dipende fortemente dall\u27individuo che lo osserva; l\u27uomo ? influenzato, infatti, da molteplici fattori: la percezione, la cultura, l\u27ambiente sono tra questi. Ci sono, per?, degli elementi che, comunemente, inducono determinate sensazioni, quali, ad esempio, il colore e la similarit? con forme note. Spostandosi alla fase di creazione, quando uno stilista esegue uno schizzo, cerca di dare all\u27oggetto una forte connotazione a livello emozionale e ottiene questo risultato tracciando delle linee caratterizzanti. La forma e, di conseguenza, la geometria, sono dunque elementi fondamentali a livello di percezione emotiva. Lo scopo del lavoro ? quello di identificare le propriet? geometriche che regolano gli effetti di queste linee portanti del disegno, passando cos? dall\u27ambito della percezione a quello della matematica. Il discorso ? finalizzato a fornire nuovi strumenti di modellazione per la progettazione mediante calcolatore. Si vuole permettere allo stilista la modifica delle linee di carattere nel modo pi? intuitivo possibile, evitando l\u27utilizzo diretto di entit? geometriche di basso livello. In particolare, vengono proposti due possibili approcci al problema (al momento limitati alle curve piane) che sfruttano, rispettivamente, algoritmi definiti per la trasformazione di una curva in una curva target e le propriet? delle NURBS

Integration between Creativity and Engineering in Industrial Design

The objective of the paper is to illustrate which are the key issues today in the industrial design workflow, paying particular attention to the most creative part of the workflow, highlighting those nodes which still make hard the styling activities and giving a brief survey of the researches aimed at smoothing the transfer of the design intent along the whole design cycle and at providing tools even more adhering at the mentality of creative people. Based on the experience gained working in two different European projects, through the collaboration with industrial designers in the automotive and the household supplies fields, a general industrial design workflow will be depicted, highlighting the main differences between the automotive and non-automotive sectors; the problems still present in the design activity will be also illustrated. The paper includes short surveys, in relation to the aesthetic design, in matter of research activities aimed at - identifying the links between shape characteristics of a product and the transmitted emotions - better supporting, in a digital way, the 2D sketching phase and the automatic interpretation and transfer of the 2D sketches into a 3D surface model - improving the 3D Modeling phase

Remarques sur le fragment L 147 : Pascal et Jansénius contre les stoïciens

Dans la première partie de la dixième liasse des Pensées, intitulée Le Souverain Bien, c'est-à-dire dans le fragment Dispute du souverain bien (L 147 / B 361), Pascal écrit : Le Souverain Bien.

En critiquant les philosophes stoïques, la liasse suit le fil de la précédente, la neuvième, intitul..

Esperienza nell'utilizzo della termochemioterapia con tecnologia Synergo nel trattamento della neoplasia vescicale non muscolo-invasiva.

La gestione dei tumori non muscolo infiltranti della vescica (NMIBC) dopo resezione endoscopica consiste generalmente nella chemio-immunoprofilassi intravescicale e nel follow-up a lungo termine. Sfortunatamente, la terapia intravescicale è associata a non trascurabili effetti tossici e conferisce risultati decisamente subottimali. Uno dei trattamenti più innovativi proposti per i NMBIC, oggetto negli ultimi 15 anni di numerosi studi clinici, è la termochemioterapia. Ad oggi, la tecnologia di riferimento, già confermata sicura e affidabile per la somministrazione del regime combinato, è rappresentata dal sistema Synergo®.Il trattamento con Synergo ha portato a un calo drastico delle recidive neoplastiche post-operatorie (un calo delle recidive dal 58% al 17% in un monitoraggio di due anni e dal 65% al 26% in un monitoraggio stimato di cinque anni).Dal 2010 questa terapia è disponibile, come alternativa terapeutica di seconda linea, presso l’U.O. di Urologia dell’Ospedale di Massa. Nel nostro studio abbiamo valutato l'efficacia e la sicurezza della terapia in 18 pazienti, di cui 12 con recidiva ad intermedio e ad alto rischio di TCC che hanno ricevuto un protocollo di trattamento termochemioterapico. Questo tipo di trattamento ha mostrato risultati incoraggianti nell’evitare la recidiva della malattia e la sua progressione. Tra i pazienti trattati è stato raggiunto un tasso privo di recidiva del 72% nel corso di un periodo di follow-up medio di 280 giorni. I risultati ottenuti per i pazienti fin’ora trattati sono positivi se si considera che la maggior parte di loro erano ad alto rischio di progressione del tumore a causa del fallimento delle precedenti terapie. Se i risultati oncologici saranno confermati da ulteriori studi, il trattamento di termochemioterapia potrebbe configurare l’approccio standard nei pazienti con neoplasia vescicale superficiale non muscolo-invasiva ad alto rischio di recidiv

I tetti verdi di tipo estensivo : biodiversità ad alta quota

Le città sono state paragonate da Odum a degli organismi eterotrofi che basano la loro crescita ed espansione sull’uso indiscriminato di risorse e sono causa di perdita irreversibile e frammentazione degli habitat naturali. I tetti verdi rappresentano uno strumento essenziale di mitigazione e compensazione ambientale all’interno del tessuto urbano dove, l’alta densità edilizia e l’elevato disturbo antropico concedono poco spazio alle dinamiche naturali. In particolare, i tetti verdi per la biodiversità caratterizzati da mosaici di micro-habitat diversi e contigui tra loro, possano ospitare specie con caratteristiche morfo-funzionali diverse. L’approccio noto come habitat template, consiste nel selezionare le specie vegetali adatte alle condizioni sui tetti estensivi tra quelle che in natura crescono in condizioni simili e.g. spessore di substrato ridotto e povero di sostanze nutritive, lunghi periodi di aridità. L’approccio fitosociologico prevede l’individuazione di habitat analoghi non solo come riferimento da cui estrapolare le specie vegetali, ma come modello per aggregare le piante in consorzi specifici, così come suggerisce l’interpretazione fitosociologica della natura.Cities are defined as heterotrophic organisms (Odum, 1983) as they consumes a huge amount of resources and causes habitat loss and fragmentation. Green roofs represents a fundamental mean of ecological compensation within the built environment, i.e. in highly altered and disturbed places by humans. In particular, green roofs for biodiversity (or biodiversity green roofs), being characterised by different but contiguous microhabitat (habitat mosaics or patches), can host several species with different functional traits. The methods known as habitat template consists of choosing suitable plant species for green roofs among the one that live in nature under similar conditions e.g. shallow and nutrient poor substrate, high drought. The phytosociological approach considers habitat analogue not only as species pools, but also as a model to group plants in specific associations as suggested in the phytosociological interpretation of nature

Biodiverse green roofs in Mediterranean climate. Input and lessons learned from Germany and Switzerland

In the realm of the doctoral program in technologies for sustainability and land restoration, this thesis deepens sustainable and ecological solutions for Mediterranean environment after the German tradition and the Swiss school of green roofs for biodiversity. Specific aims were to: (1) assess the effectiveness of the existing green roofs norms in supporting biodiversity; (2) review methodologies and approaches for the implementation of biodiverse green roofs but also their application for ecological design; (3) identify habitat templates in the Mediterranean ecoregion replicable on green roofs; and (4) investigate the long term vegetation development of unmanaged green roofs in order to give ecological design guidance. As regards the green roof norms assessment, the German guidelines were chosen for its traditional referential role, the Swiss norm for its peculiar biodiversity approach, the Italian one for affecting a territory with remarkably heterogeneous environmental conditions, stretching from Alpine to Mediterranean ecosystems. Even if the three regulations at comparison addressed to some extent biodiversity related matters, none of them focused on the peculiarities of different ecoregions in term of plant species selection and assemblage, growing medium composition (materials and granular size) and system build-ups (multi-layers and single-layer construction). It was concluded that at the current knowledge, an official and effective regulation for green roof design in Mediterranean ecoregion is still missing. Biodiverse green roofs, being characterised by different and contiguous microhabitats (habitat mosaics or patches) can host several species with different morphological and functional traits (Brenneisen, 2003). As regards their implementation methods and approaches, the habitat template consists in choosing suitable plant species among the one living in nature under similar conditions e.g. shallow and nutrient poor substrate and drought, while the phytosociological approach applied to green roofs considers habitat analogues not only as species pools, but also as models to group plants in specific associations. It was concluded that nature conservation approaches on green roofs offer new perspectives for urban sustainability and for ecological design. However, in order to give the “naturalistic” approach a chance to develop extensively, it is necessary to act into the education and technical spheres: sensitizing the public opinion starting from the new generations (eco-litteracy) and training professionals able to conjugate scientific knowledge (analytic phase) and design (creative phase). An Eco-designer should operate considering the local climatic conditions, the potential vegetation and the interactions with neighbouring biocenosis: he/she has to be also an ecologist in order to combine the ways of nature to the ways of man. As regards replicable habitat on green roofs in Mediterranean areas, the proposed methodology approach was based on a practical plant sociology understanding of EU Directive 92/43: a recognition of Natura 2000 habitat that could be imitated on roofs in terms of characteristic species and substrates. The results lead to three groups: those linked to sandy substrates (psammophilous vegetation), to gravely-pebbly substrates (glareicolous vegetation) and to xeromorfic soils (garrigues and dry grasslands). Desirable plants establishment methods on green roofs should be based on diaspore hay- transfer and threshing from selected donor meadows, as it happens for grasslands restoration. Finally, as regards the long term vegetation development over a thirty year period, results demonstrated that the main driver of the observed functional changes on undisturbed simple-intensive green roofs in temperate climate, was a shift towards relatively more thermo-xeric conditions. In terms of plant life strategies, the competitive species sown on the roof gradually gave way to stress-tolerant and ruderal species, along with a progressive increase in species with short-distance seed dispersal strategies. It is concluded that: (a) to create resilient green roofs, spontaneous colonisation should be accepted and considered as a design factor; and (b) regional plant communities could serve as a model for seed recruitment and design

Wenn sich die Biodiversität im Hochbau durchsetzt : digitale Instrumente und Methoden für eine nachhaltige Immobilienentwicklung

Der Ansatz von Planern und Landschaftsarchitekten unterscheidet sich stark von dem der Ökologen und Naturwissenschaftler. Eine grosse Herausforderung besteht darin, diese zwei Welten zu verbinden: Ökologie und Immobilienbranche. Das DeMo-Projekt setzt die Grundlagen für einen multidisziplinären Gestaltungsrahmen, der das Problem des Verlusts der biologischen Vielfalt in der städtischen Umwelt durch naturnahe Gestaltung angeht. Die Methode berücksichtigt den Massstab Gebäude – Stadt – Landschaft und wird durch neue digitale Technologien ermöglicht

Towards an automatic semantic annotation of car aesthetics

The design of a new car is guided by a set of directives indicating the target market and specific engineering and aesthetic constraints, which may include also the preservation of the company brand identity or the restyling of products already on the market. When creating a new product designers are used to evaluating other existing products to take inspiration or to possibly reuse successful solutions. In the perspective of an optimised styling workflow a great benefit could come from the opportunity of easily retrieving the related documentation and existing digital models both from internal and external repositories. In fact, the rapid growth of the web contents and the widely spread adoption of computerassisted design tools have made a huge amount of digital data available, whose exploitation could be improved by more selective retrieval methods. In particular, the retrieval of aesthetic elements may help designers to more efficiently create digital models conforming to specific styling properties. The aim of the research described in this document is the definition of a framework able to support a (semi-) automatic extraction of semantic data from 3D models and other multimedia data to allow car designers to reuse knowledge and design solutions within the styling department. The first objective is then capturing and structuring both the explicit and implicit elements that contribute to the car aesthetics and can be realistically tackled through computational models and methods. The second step is the definition of a system architecture able to transfer such semantics through an automatic annotation of car models
