Architettura in alzato. Questioni di territorio, paesaggio, ambiente
2021
Negata alla tipologia l’architettura del Sud nel saggio riconosce una specifica identità e perfetta eccezionalità nell’essenza del luogo. Se la facciata istituisce un rapporto con l’estetica del paesaggio, i temi che essa sottende definiscono altre significative relazioni. L’ordinamento logico delle membrature, la chiarezza geometrica e il rigore dei rapporti rimandano ad una architettura che si misura, ed è misura stessa, del territorio e della sua morfologia. A sua volta, lo spessore della facciata esprime la relazione con l’ambiente e interpreta in maniera poetica i condizionamenti climatici, intervenendo sul controllo della luce, sui vuoti nei paramenti murari, sulla determinazione dell…
A study on Norwegian companies in China: Challenges & successful strategies
2016
Master thesis Business Administration BE501 - University of Agder 2016 This paper examines what governmental and cultural challenges Norwegian companies face when entering and doing business in China. In addition, this paper also discusses what strategies to implement to overcome these challenges. With China becoming a bigger player in the global marketplace, this is an important matter not only for companies across the world but also for Norwegian companies. Through a qualitative research method with semi-structured interviews, the research is conducted on four Norwegian companies who does business in China. The findings shows that there are many variables affecting the choice of entry mod…
Fundamental characterisation of reclaimed asphalts: The importance of testing homogeneous specimens
2013
This study highlights the importance of defining appropriate specimen manufacturing procedures when assessing the fundamental properties of reclaimed asphalt (RA) mixes for further modelling purposes. Two gyratory compactor procedures were used: the first leading to specimens with a non-uniform air voids distribution and the second tailored to obtain homogeneous specimens. The study was performed by using three stone mastic asphalts incorporating up to 30% of RA but designed to have identical properties. A detailed characterisation of the loose mixes and binders, an X-ray computer tomography micro-structural study of the manufactured specimens and a further mechanical characterisation showe…
Effect of mixing time on reclaimed asphalt mixtures: An investigation by means of imaging techniques
2015
This paper presents an application of imaging techniques to investigate the distribution of reclaimed asphalt and air voids within gyratory compacted specimen. Stone Mastic Asphalt specimens containing reclaimed asphalt, were produced at five different laboratories participating in the collaborative project Re-Road: University of Nottingham, Belgium Road Research Centre, Danish Road Directorate, TU Braunschweig and Laboratoire Centrale de Ponts et Chaussees (now IFSTTAR). This study applies the X-ray Computed Tomography and Optical Microscopy techniques to view the internal structure of the specimen with particular focus on the air voids and reclaimed asphalt distributions within the specim…
Influence of resin viscosity and vacuum level on mechanical performance of sandwich structures manufactured by vacuum bagging
2010
The choice of process parameters is critical in optimizing the mechanical properties of sandwich structures produced using the vacuum bagging technique. The aim of this paper is to analyze how the viscosity of the resin/curing agent system and the vacuum level influence the morphology and the mechanical behavior of sandwich beams with composite faces (epoxy resin and glass fiber fabric named COMBI 900) and a PVC foam core. Four different sandwich structures were produced by varying the viscosity of the epoxy resin/curing agent at constant maximum vacuum pressure. Three further structures were manufactured by varying the strength of the vacuum with the resin viscosity maintained constant at …
Past and present “Urban voids” as resources for the future. The case-study of Catania
2002
Since the end of the 1960s, the landscapes of major cities have been more and more characterized by the presence of "urban voids". Today these "voids", which are often heterogeneous in their manifestation, dominate the discussions about the transformation and the future of urban areas. The reclaiming and re-use of derelict sites and "cultural heritage" has the duty to assure for the next generation the knowledge of the cultural values of the past. In this paper we will focus our attention on a re-used "cultural heritage": the Multifunctional Centre of Catania (Sicily, Objective 1 region). Thanks to the Urban Programme this "urban void"- abandoned for decades and deteriorated - was recovered…
Semantics of Voids within Data: Ignorance-Aware Machine Learning
2021
Operating with ignorance is an important concern of geographical information science when the objective is to discover knowledge from the imperfect spatial data. Data mining (driven by knowledge discovery tools) is about processing available (observed, known, and understood) samples of data aiming to build a model (e.g., a classifier) to handle data samples that are not yet observed, known, or understood. These tools traditionally take semantically labeled samples of the available data (known facts) as an input for learning. We want to challenge the indispensability of this approach, and we suggest considering the things the other way around. What if the task would be as follows: how to buil…
