Locally Produced UHPC: The Influence of Type and Content of Steel Fibres
2021
Abstract Ultra-high performance concrete might be a competitive alternative to normal concrete for some purposes. But despite research efforts during decades, utilisation is still not widespread. Reasons include limited competence and material availability. This paper presents one step of a research initiative aimed at facilitating the use of UHPC in Norway. The step presented here comprises the accumulated results from investigations on the influence steel fibres (content, type, and hybrid combination) have on material strength and deformation behaviour of locally produced UHPC, made with constituents found in southern Norway. 231 specimens were tested, spanning nine UHPC mixes. Digital Im…
Digital Twin framework for automated fault source detection and prediction for comfort performance evaluation of existing non-residential Norwegian b…
2023
Numerous buildings fall short of expectations regarding occupant satisfaction, sustainability, or energy efficiency. In this paper, the performance of buildings in terms of occupant comfort is evaluated using a probabilistic model based on Bayesian networks (BNs). The BN model is founded on an in-depth anal- ysis of satisfaction survey responses and a thorough study of building performance parameters. This study also presents a user-friendly visualization compatible with BIM to simplify data collecting in two case studies from Norway with data from 2019 to 2022. This paper proposes a novel Digital Twin approach for incorporating building information modeling (BIM) with real-time sensor data…
Comparative study of indirect tensile test and uniaxial compression test on asphalt mixtures: Dynamic modulus and stress-strain state
2023
Dynamic modulus is an essential parameter for the performance characterisation of asphalt materials for performance prediction and pavement design. The Indirect Tensile (IDT) test and the Uniaxial Compression (UC) test are both well-known experiments performed in the laboratory to characterise the dynamic modulus of asphalt mixtures over a range of temperatures and loading frequencies. A considerable amount of research has investigated the difference between two test modes, while few studies analysed the fundamental difference in stress–strain distributions for the two test setups. This work aims at comparing the effect of the two test methods on dynamic modulus of asphalt mixtures, as well…
Būvniecības nozares attīstības tendences Latvijā.
2019
Būvniecības nozares attīstības tendenču novērtējums ir būtiska sastāvdaļa tās ilgtspējīgai darbībai. Izpratne par esošās situācijas rādītāju ietekmi un tās gaidāmajām pārmaiņām dod iespēju laicīgi veikt pareizus un ekonomiski pamatotus stratēģiskos lēmumus. Bakalaura darba mērķis ir: atklāt nozares trūkumus, riskus un iespējas, kā arī prognozēt būvniecības nozares attīstības tendences Latvijā un izvirzīt priekšlikumus nozares veiksmīgai darbībai. Pirmajā nodaļā tiek veidota darba teorijas bāze izmantojot pieejamo nozares zinātnisko literatūru. Otrajā nodaļā tiks veikts statistikas apkopojums par līdzšinējo situāciju nozarē apkopojot statistikas datus pat nozares rādītājiem. Trešajā noslēdzo…
50 Shades of Green: Insights into Personal Values and Worldviews as Drivers of Green Purchasing Intention, Behaviour, and Experience
2021
Despite the booming interest in determinants of green (i.e., sustainable) consumption, the psychological factors that influence pro-environmental consumption patterns are not yet fully understood. To answer this call, we developed and analysed a model that offers an integrative approach to sustainable consumption patterns by addressing the full palette of consumers’ personal value orientations. Specifically, we linked consumers’ egoistic, altruistic, and biospheric values at the personal level to pro-environmental purchasing intentions, behaviours, and experiences. Furthermore, we examined whether implicit beliefs about the balance between humanity and nature (i.e., worldviews) moderate the…
Road Functional Classification Using Pattern Recognition Techniques
2019
The existing international standards suggest a methodology to assign a specific functional class to a road, by the values of some features, both geometrical and use-related. Sometimes, these characteristics are in contrast with each other and direct the analyst towards conflicting classes for a road or, worse, one or more of these features vary heterogeneously along the road. In these conditions, the analyst assigns the class that, by his capability and experience, he retains the most appropriate, in a very subjective way. On the contrary, the definition of an automatic procedure assuring an objective identification of the most appropriate functional class for each road would be desirable. …
Preservation of the artistic heritage within the seat of the Chancellorship of the University of Palermo
2006
The correct maintenance of artworks of historical and artistic value requires a wide and detailed analysis of all the information relevant for preserving them, such as identification of the main deterioration factors, knowledge of the climatic history of the object, set-up of measuring methods and statistics of the guide parameters, and definition of a set of recommended environmental aspects to be controlled within a stable climate condition linked to the particular kind of object or its surface. In Italy, the basic laws UNI 10829 and UNI 10969 impose a reference methodology for the in-field measurement and data analysis. This paper reports the first results of a measuring campaign, carrie…
Alliances between For-Profit and Non-Profit Organizations as an Instrument to Implement the Economy for the Common Good
2020
The model of the Economy for the Common Good (ECG) has cooperation as one of its main principles. This alternative economic model proposes to prioritize cooperation over competition to favor the creation of social value. From this point of view, strategic alliances between organizations can be used as an instrument that supports implementation of the ECG model. In recent years, alliances between for-profit and non-profit entities have been strengthened as a method to facilitate actions focused on social responsibility and sustainability. Moreover, the ECG model has become an adequate management framework for corporate sustainability. This work aims to connect alliances between for-profit an…
Comparative Analysis of Mega Road Construction Projects in Term of Innovation
2020
Purpose This paper examines, using critical realism, the causes and mechanisms of innovation in three civil road construction projects. Its focus is to examine how value can be created within the design process through innovation. Emphasis is placed on Best Value Procurement (BVP) as a procurement strategy where the preferred contractor is considered the expert, as it is the first case of its use in Norwegian road construction projects. Data was collected through surveys and interviews. Findings indicate that procurement using early involvement is innovative in the design process yet must be adapted, to allow for early planning of innovative ideas that help, to foster innovative solutions. …
