Tecnologie costruttive “appropriate ed appropriabili”: tipicità dell’architettura informale
No full textTypicality in architecture is an issue closely linked to the construction. A landscape is defined as "typical" when it is possible to acknowledge some essential features, concerning the urban structure, the building types, materials or colour. There is a reality that, although without structured rules, reveals however a typical landscape, defining the so-called "informal architecture". Slums, favelas, earthen villages. These are places at the margins of the city in the South of the World, where people live in overcrowded conditions, in total absence of services. In these contexts, the intervention of architects lacks and any urban plan or project order is considered unnecessary. Only what is strictly required is constructed and the so-called "spontaneous architecture" is generated. However a kind of homogeneity of architectural language is still discernible. Relatively to production systems and construction, an interesting research was carried by the team named “Casapartes” that has distinguished two different types of technologies: "appropriate and appropriable"
A Global Existence Result for a Semilinear Wave Equation with Lower Order Terms on Compact Lie Groups
No full textIn this paper, we study the semilinear wave equation with lower order terms (damping and mass) and with power type nonlinearity | u| p on compact Lie groups. We will prove the global in time existence of small data solutions in the evolution energy space without requiring any lower bounds for p> 1. In our approach, we employ some results from Fourier analysis on compact Lie groups
Travelling along the coast. The revelation of the Sicilian war architectures/ Itinerari lungo la costa. la rivelazione delle architetture belliche siciliane
No full textIn his work, Jaime Lerner argues that a good acupuncture is “almost always a spark
that initiates an action, and the subsequent propagation of that action” (Lerner, 2003).
Acupunctures are small and punctual interventions aimed at generating much wider
effects from their own scale of implementation; they are actions to promote the cultural
identity of a place, designed to induce behaviours of discovery and knowledge of the
territory itself. These are principles that could find perfect fulfilment in Sicily, a region
rich in architectural testimonies peculiar to our history: the war architectures of the
Second World War. These are small buildings, extraordinary control stations, called
pillboxes and casemates, which for reasons clearly strategic and to optimize the views of the territory, are often found along the coast. This article proposes the conception of
thematic itineraries that, through a network of pillboxes, promote the enhancement of
the landscape and of the architectures themselves. These architectural objects are, in
fact, an extraordinary part of our heritage that can aspire to become new tools for narrating
places, of history and of what has been and what is war in the collective memory
Semilinear wave equation on compact Lie groups
No full textIn this note, we study the semilinear wave equation with power nonlinearity |u|^p on compact Lie groups. First, we prove a local in time existence result in the energy space via Fourier analysis on compact Lie groups. Then, we prove a blow-up result for the semilinear Cauchy problem for any p> 1 , under suitable sign assumptions for the initial data. Furthermore, sharp lifespan estimates for local (in time) solutions are derived
Trastevere - A pubblic space
No full textViene presentato un progetto per Trastevere (Roma), la zona della vecchia stazione, in cui è stato inserito un intervento di social housing che ridisegnasse lo spazio pubblico e definisse nuove attività commerciali. La proposta avanzata prevede la realizzazione di una piazza che raccorda i salti di quota alle estremità del lotto ed un nuovo edificio residenziale che possa venire incontro a nuove e diverse esigenze dell’abitare
