Analysis of gas sensors array signals for evaluation of mold contamination in buildings
2018
Mold is considered to be one of the most important features of Sick Building Syndrome (SBS) and is an important problem in building sector. In numerous cases it is caused by the rising moisture of building envelopes and overstated humidity of indoor air. Fungal contamination is normally evaluated using standard biological methods which are time-consuming and require a lot of manual labor. But also, fungi emit Volatile Organic Compounds (VOC) that can be detected in the indoor air using several techniques of detection e.g. chromatography. VOCs can be also detected using gas sensors arrays. All arrays of sensors generate particular electric signals that ought to be analyzed using statistical …
Bivalve mollusks shells valorisation and recycling: market potentiality and novel building products
2023
Construction is a fundamental driver of the world economy, recognized as a sector that generates a great contribution to the social and economic development. At the same time, it shows an enormous environmental impact through an unstoppable consumption of non-renewable resources, a high energy consumption, and an associated atmospheric emission of pollutant. Consequently, the research and development of novel and green production processes and sustainable building materials is of paramount importance. The sustainability of materials and production processes could be improved by enhancing and reusing wastes from various industrial sectors. In this paper, the fishery sector will be analysed, …
Unions and industrial improvement projects: Building a common momentum
2018
The purpose of this article is to define the potential role unions can play in a general quest for improved practice in an industrial company. Workplace innovation (WPI) is one example of such a measure. Lean is another. The article outlines important elements when implementing improvement tools like Workplace Innovation and Lean practice. The efforts are focused at company level, and experiences from a Norwegian industrial company highlight the areas of importance. The amplifying role a union can play in an improvement process is discussed, and motives and processes are clarified, in order to show the role of unions in a broader sense. The “Nordic” tradition of organising work-life frames …
Organs as an exemplification of the material heritage of Montenegrin culture. Part. 2: St. Nicholas' Church and the Church of Our Lady of the Rock in…

Montenegro became a union republic of the Socialist Republic of Yugoslavia (1945–1992) after the Second World War and the political changes and wars in the Balkans at the turn of the 20th and 21st century. Montenegro proclaimed its independence on 3rd June 2006. As an independent state, this former republic of socialist Yugoslavia takes action to gather and scientifically describe its remarkable cultural heritage. In 2019 Cetinje Academy of Music, which is part of the University of Montenegro, decided to carry out a scientific project aimed at depicting this entire cultural heritage. Folk culture and Orthodoxy are the dominant features of this whole opus, thus it is not surprising that cult…

Effect of ageing on the morphology and creep and recovery of polymer-modified bitumens
2018
Polymer additives are used to improve the properties of road bitumens including their oxidative resistance. However, their usage as anti-oxidative materials remains relatively unclear. This study aims to investigate the changes in the morphology and the rheological response of polymer modified bitumens used in road pavement construction caused by ageing. An elastomer (radial styrene butadiene styrene, SBS) and a plastomer (ethyl vinyl acetate, EVA) polymer were mixed with one base bitumen at three polymer concentrations. The bitumens were RTFO and PAV aged. The morphology of the bitumens was captured by fluorescence microscopy while the rheological properties were measured by means of the m…
Cavaillon (84), Ancienne cathédrale Notre-Dame-et-Saint-Véran. Suivi archéologique de sondages géotechniques
2023
Pour les besoins de l’étude géotechnique, six sondages ont été creusés dans et autour de l’ancienne cathédrale de Cavaillon en février 2020. Ils avaient pour objectif de comprendre les désordres structurels observés sur l’édifice en mettant à jour les fondations des différentes constructions (chapelles, chevet, nef et annexe). Compte-tenu du contexte archéologique, le Service Régional de l’Archéologie de PACA a prescrit leur suivi archéologique. L’objectif était de documenter les niveaux d’occupation mis au jour sans détruire les vestiges remarquables, en particulier les maçonneries et les sépultures. Parmi les sondages, les trois situés au nord de l’ancienne cathédrale, le long de la rue D…
A Hybrid AHP Approach and GIS-Based Methods as Fundamental Tools in the SECAP’s Decision-Making Process
2023
Adapting to climate change and mitigating its impacts are the main challenges for cities today. One objective that the European Commission has set in recent decades is reducing climate change inaction, and several political actions have been implemented. Among these actions, the Covenant of Mayors led to the development and adoption of Sustainable Energy and Climate Action Plans (SECAPs) by many cities worldwide. A challenge that local authorities must face during the development of a SECAP is the identification of the policies to be included in the plan. This paper presents a case study to show the validity of using a hybrid analytic hierarchy process (AHP) approach and various geographic …
Comparison of different predictive models for nutrient estimation in a sequencing batch reactor for wastewater treatment
2006
Abstract In this paper different predictive models for nutrient estimation in a sequencing batch reactor (SBR) for wastewater treatment are compared: principal component regression (PCR), partial least squares (PLS), and artificial neural networks (ANNs). Two unfolding procedures were used: batch-wise and variable-wise. For the latter unfolding method, X and Y matrix augmentation with lagged variables were used in some models to incorporate process dynamics. The results have shown that batch-wise unfolding PLS models outperform the other approaches. The ANN models are good predictive models, but in this particular case-study, they do not outperform those multivariate projection models that …
Probabilistic Flood Hazard Mapping Using Bivariate Analysis Based on Copulas
2017
This study presents a methodology to extract probabilistic flood hazard maps in an area subject to flood risk, taking into account uncertainties in the definition of design hydrographs. Particularly, the authors present a new method to produce probabilistic inundation and flood hazard maps in which the hydrological input (i.e., synthetic flood design event) to a 2D hydraulic model has been obtained by using a bivariate statistical analysis (copulas) to generate flood peak discharges and volumes. This study also aims to quantify the contribution of boundary conditions’ uncertainty in order to evaluate the effect of this uncertainty source on probabilistic flood hazard mapping. Different comb…
