A New Methodology to Assess Territorial Competence for Sustainable Local Development: The READI® (Resources-Actors-Dynamics) Matrix
2021
[EN] The ability of a territory to manage certain sustainable development processes increasingly depends on its capacity to apply previous diagnostic processes to its current situation. For this reason, methodologies that facilitate the detection of needs and/or potentialities of the territory are key to meeting its anticipated sustainable development goals. We present the most notable results of the research methodology carried out in the province of Valencia (Spain) that has enabled the construction of a matrix of indicators that allow these previous diagnostic processes to be put into practice at a local level, based on the participation of the territory's socioeconomic actors.
From Waste to Resource – Utilising Residue from Ready-Made Concrete as New Aggregate
2021
Abstract A new admixture is available, to reduce the sludge produced from the cleansing of production and transportation equipment in the fresh concrete industry. The result is agglomerations of hardening concrete, that might be utilised for aggregate. Utilisation depends on adequate properties. This paper reports from investigations on the physical and mechanical properties of the aggregate and discussions on the performance relative to natural and recycled aggregates and towards requirements for utilisation. The findings indicate substantial potential for utilisation, supporting the reduction of waste for deposit and development of the concrete industry towards a circular economy.
Use and Identification of Components in Component-Based Software Development Methods
2000
New software systems are needed ever more but to keep up with this trend software developers must learn to create quality software more efficiently. One approach is to (re-)use components as building blocks of the new software. Recently there has been more interest to create component-based software development methods to support this. In this article we first set out requirements for reuse-based software development and then evaluate three component-based methods, namely Catalysis, OMT++, and Unified Process. As a conclusion we argue that evaluated methods produce prefabricated components and that component-based means that software developers can change better components to existing syste…
Developing Software with Domain-Driven Model Reuse
2015
This chapter presents an approach to software development where model-driven development and software reuse facilities are combined in a natural way. It shows how model transformations building a Platform Independent Model (PIM) can be applied directly to the requirements specified in RSL by domain experts. Further development of the software case (PSM, code) is also supported by transformations, which in addition ensure a rich traceability within the software case. Alternatively, the PSM model and code can also be generated directly from requirements in RSL, thus providing fast development of the final code of at least a system prototype in many situations. The reuse support relies on a si…
Improving the rheometry of rubberized bitumen: experimental and computation fluid dynamics studies
2017
Abstract Multi-phase materials are common in several fields of engineering and rheological measurements are intensively adopted for their development and quality control. Unfortunately, due to the complexity of these materials, accurate measurements can be challenging. This is the case of bitumen-rubber blends used in civil engineering as binders for several applications such as asphalt concrete for road pavements but recently also for roofing membranes. These materials can be considered as heterogeneous blends of fluid and particles with different densities. Due to this nature the two components tends to separate and this phenomenon can be enhanced with inappropriate design and mixing. Thi…
I Telamoni del Tempio di Zeus ad Agrigento: rilievi, disegni e ricostruzioni
2013
Oggetto dello studio qui presentato è la ricostruzione di un intercolumnio del fronte esterno del Tempio di Zeus ad Agrigento, basata sul rilievo del Telamone oggi custodito presso il Museo Archeologico, sugli studi e i numerosi saggi di ricostruzione proposti dagli studiosi dal XVIII secolo fino alla metà dello scorso secolo e sulla analisi strutturale del Telamone ricostruito nel Museo. The drawings of the telamones, the giant statues placed the front of the Temple of Zeus in the archaeological area of Agrigento, have fascinated some of the most famous neoclassical architects in Europe. The virtual reconstruction of one intercolumnial of the Temple, based both on the range-based survey of…
Il Caffè Arabo alla IV Esposizione Nazionale di Palermo: dai disegni di Ernesto Basile alla ricostruzione virtuale
2016
A partire dalla rilettura di disegni originali di progetto e riproduzioni grafiche d’epoca, il contributo indaga il caffè arabo progettato da Ernesto Basile per la IV Esposizione Nazionale di Palermo. Il presente studio rientra nel filone delle ricostruzioni virtuali di architetture non più esistenti o solo disegnate e si configura quale tassello mancante di un lavoro più ampio e già edito riguardante la maggior parte del complesso espositivo. La ricostruzione virtuale si connota quale strumento di indagine e visualizzazione di un’architettura effimera, in una parte di città perduta. This text studies the project for the Caffé Arabo designed by Ernesto Basile for the IV Esposizione Nazional…
The reconstruction project: The district Villarosa
2016
Il concorso per il complesso di edifici di Piazzale Ungheria, avrebbe dovuto suggellare la sistemazione del rione “Villarosa”. Sulla base di documenti pervenuti e uno studio teso alla definizione architettonica si è realizzata la restituzione grafica tesa ad evidenziare la complessità geometrica e gli effetti spaziali generati dal gioco di volumi, utilizzando solo la presenza della luce naturale e non foto-realistici. L’inserimento del modello virtuale nella configurazione odierna ha dimostrato la perdita dei concetti di organicità esposti dal progetto vincitore assenti nello stato attuale. The competition for the complex of buildings Ungheria Square, should have sealed the ward accommodati…
Afternotes on PHM: Harmonic ENO Methods
2003
PHM methods have been used successfully as reconstruction procedures to design high-order Riemann solvers for nonlinear scalar and systems of conservation laws, (see [8], [1], [4]). We introduce a new class of polynomial reconstruction procedures based on the harmonic mean of the absolute values of finite diferences used as difference-limiter, following the original idea used before to design the piecewise hyperbolic method, introduced in [8]. We call those methods ’harmonic ENO methods’, (HENO). Furthermore, we give analytical and numerical evidence of the good behavior of these methods used as reconstruction procedures for the numerical approximation by means of shock-capturing methods fo…
A Maximizing Hydraulic Radius (MHR) method for defining cross-section limits in rills and ephemeral gullies
2021
Abstract In this paper, a new method for determining the cross-section limits in rills and ephemeral gullies is proposed. This method is based on the estimate of the actual depth ha of each cross-section, which is the particular depth distinguishing the channel from the hillslope areas. The analysis showed that the actual depth corresponds to a particular bank slope sta occurring for the maximum value of the hydraulic radius R. The method was applied using a volumetric approach for calculating the hydraulic radius as the ratio between the volume of the whole investigated channel and its boundary lateral surface. The value of the bank slope st was derived by the DEM of the whole channel late…
