On the hygrothermal behavior of coconuts fiber insulators on green roofs.
2020
Coconut fibre insulators, represent an insulating material considered as “exotic”, which clashes with the doubts of his thermo-hygrometric behavior, in particular, in the case of covering technology such as green roofs, a technological solution adopted in the case of sustainable buildings or nearly zero energy building. Green roofs represent a valid constructive solution with high thermal performances, adopted in existing and new buildings. The purpose of the research regards the study of the thermo-hygrometric behavior of the concrete and Cross-Laminated Timber (CLT) slabs, insulated with coconut fibre-boards (CF) such as alternative synthetic insulators, referred to 10 different green roo…
Improvement of energy efficiency and quality of street lighting in South Italy as an action of Sustainable Energy Action Plans. The case study of Com…
2015
Abstract Existing street lighting systems, in most of South Italy cities, are often inefficient due to the obsolescence of lamps and luminaires and of ineffective light control systems unable to implement efficient on-off and dimming strategies. Energy efficiency improvement, in street lighting systems, is often one of the key actions to be adopted by Public Administration in their Sustainable Energy Action Plan in the framework of the “Covenant of Majors” activities. As a task of FACTOR 20 project, a set of planning options has been analysed and proposed. Particularly, street lighting efficiency projects have been studied for representative case studies. A detailed survey of the public lig…
Backcalculation of airport pavement moduli and thickness using the Lévy Ant Colony Optimization Algorithm
2016
Interpretation of NDTdata is crucial in any Airport Pavement Management System (APMS), in order to implement strategies to maintain airport pavementssince they allow to estimate their remaining life and related maintenance needs and activities. In this paper, the AntColony Optimization algorithmwasused for backcalculation of pavement moduli from surface deflection data. The algorithm’s performances are illustrated and improvement in prediction quality is demonstrated both in terms of goodness of fitness and computational effort. Moreover, it is proved that the proposed algorithm is also able to predict layer thicknesses, taking into account their variation too.
Multicriteria evaluation of heating choices for a new sustainable residential area
2015
Abstract The city of Loviisa in Finland is planning a new sustainable residential area with a total of 240,000 m2 of residential houses and apartment buildings with services. The city wants to promote sustainable energy solutions in the area, considering various renewable energy forms for heating. The aim of this research is to evaluate which heating system would be best for a new single-family house when different technical, economic, environmental and usability criteria are considered. A group of experts evaluated the alternative heating systems with respect to the criteria. The citizens were involved with a questionnaire to provide preference information for different criteria. Altogethe…
Recommendation of RILEM TC237-SIB: protocol for characterization of recycled asphalt (RA) materials for pavement applications
2018
This recommendation proposes an experimental protocol to characterize Recycled Asphalt (RA) materials. The guidelines presented in this document are based on the results of a Round Robin Test (RRT) organized by the RILEM Technical Committee 237-SIB “Testing and characterization of sustainable innovative bituminous materials and systems” and provide information on the testing procedure, data analysis and indications for the preparation of a test report.
Optimizing the Methodology of Characterization of Municipal Solid Waste in EU under a Circular Economy Perspective
2017
Abstract The methodology for the characterization of residual municipal solid waste (RMSW) is available since decades. Some modifications have been introduced in order to modernize it. Now, in order to take into account the targets of the circular economy, an additional effort must be made to be sure of generating the right information suitable for the optimization of municipal solid waste in that frame. In that perspective, the Authors present a few proposals in order to avoid mistakes and to deepen the reliability of the data generated during the analysis performed to classify the residual municipal solid waste in fractions. A new model of characterization is thus proposed, suitable for p…
Surveying, Analysis and 3D Modeling in Archaeological Virtual Reconstruction. The inner colonnade of the naos of Temple G of Selinunte.
2012
This paper is focused on the virtual reconstruction of a portion of the naos of Temple G of Selinunte, as a case study for the definition of a method of virtual anastylosis and reconstruction of collapsed colonnades in archaeological contexts. Reconstruction is based on the combination of historical research, archaeological analysis, digital surveying, image-based modeling and laser scanning methods. The complexity of the ruins of the temple suggested a thorough archaeological analysis of the fragments of the inner colonnade of the naos. This analysis made it possible to identify reference surfaces and protective or sacrificial surfaces. The study of these surfaces, together with the dimens…
Linguistic Repertoires and Semiotic Resources in Interaction: A Finnish Manager as a Mediator in a Multilingual Meeting
2010
This article examines professional communication in a multilingual meeting in a small company in Finland within ethnographic, sociolinguistic, and discourse analytic frameworks. English is used as a lingua franca by a group of Finnish and Chinese business professionals. The aim is to study how language is used with other semiotic resources to construct meaning in interaction. In particular, with the focus on an individual participant who was the mediator in the meeting, the goal is to analyze participants’ role alignment and interpersonal relationships. The results show that business professionals’ roles are renegotiable in a meeting and by means of language accompanied by embodied actions …
¿Puede hablarse de consenso constructivista en la educación científica?
2021
Artículo colectivo sobre qué entendemos por "constructivismo" en enseñanza de las ciencias. In this paper we analyse some of the criticisms that are being made to the «constructivist paradigm» and their implications on the development of the didactic of the sciences as a theoretical body knowledge.
Creative Project-based learning to boost technology innovation
2017
This paper shows the results of the application of a project-based learning methodology that blended flipped classroom and face-to-face sessions, along with creativity and lateral thinking techniques, to integrate the expected concepts and procedures of technology innovation and boost entrepreneurship among students of Master?s degree in chemical engineering. The constructive alignment between the expected learning outcomes and skills with the proposed activities and assessment methods was decisive in the design of the methodology, which tractor activity was the creation of an innovation project. The use of techniques of creativity promoted lateral thinking and originality in the definition…
