Global sensitivity analysis in environmental water quality modelling: Where do we stand?
2014
Global sensitivity analysis (GSA) is a valuable tool to support the use of mathematical models for environmental systems. During the last years the water quality modelling field has embraced the use of GSA. Environmental water quality modellers have tried to transfer the knowledge and experience acquired in other disciplines. The main objective of this paper is to provide an informed problem statement of the issues surrounding GSA applications in the environmental water quality modelling field. Specifically, this paper aims at identifying, for each GSA method, the potential use, the critical issues to be solved and the limits identified in a comprehensive literature review. The paper shows …
Modelling Dynamic Systems: Examples Involving an Iconic Oriented Environment
2005
We present a modelling environment based on the use of iconic representations consisting of elements, as containers and connected flows, able to describe the relationships between relevant variables of dynamic systems. The procedures involved are aimed to make students aware of the reasoning processes to describe, formalise and explain complex system behaviours. Moreover, we show how these strategies may allow the overcoming of some well-known difficulties involved in pupil understanding of mathematical formalisms, such as derivatives and differential equations and their real meaning. Our reported modelling examples were experimented on during some laboratory sessions of the Pre-Service Sch…
Modelling of managerial competences in health care units – preliminary assumptions
2022
Purpose: The aim of the article is to present the theoretical assumptions of the model of managerial competences in health care units. It was assumed that competences are a multidimensional concept and require an integrated approach that allows for the construction of a competency model that reflects their real complexity. A list of managerial competencies will be presented, which will be subject to empirical verification in the course of future research by the authors in order to identify key competencies. Design/methodology/approach: The proposed lists of managerial competencies (six domains) were created and are based on the analysis of healthcare competencies models – the study of the l…
Impact of the Solar Irradiation Angle on the Work of Modules with Spherical Cells - Simulation
2018
The main purpose of all PV modules is to convert solar energy into electricity, but in the era of building integrated photovoltaics, there are additional opportunities to use them. The use of them as a composite of architectural structures in the form of facade cladding, roofing, stained glass windows or noise barriers on highways, in addition to generating electricity embellish also the aesthetic value of the facilities. However, these atypical their use, cause that the modules should have quite different properties then in the traditional application, which is related to their unusual way of positioning. Particularly for structures such as the modules made of spherical cells with the two …

It takes the Entire University Community to Educate Students in Becoming Academics
2018
Development of scientific thinking is considered an essential but challenging aim of academic studies. In practice, this challenge becomes evident when students begin preparing their theses. Therefore, proper guidance combined with suitable guidance methods are needed. The staff of university libraries face this daily challenge through students’ questions, which often start as ‘what’ questions and morph into ‘how’ questions. Based on these genuine necessities, a new collaborative model to implement guidance for students was developed at the Open Science Centre, Library at Jyväskylä University, Finland. The model is constructed of three intertwined principles: 1) strengthening student agency…
It takes the Entire University Community to Educate Students in Becoming Academics

Poster at The 8th Edition of The Future of Education International Conference. Florence, Italy, June 28-29, 2018. Development of scientific thinking is considered an essential but challenging aim of academic studies. In practice, this challenge becomes evident when students begin preparing their theses. Therefore, proper guidance combined with suitable guidance methods are needed. Based on students’ genuine necessities, a new collaborative model to implement guidance for students was developed at the Open Science Centre, Library at University of Jyväskylä, Finland. The model is constructed of three intertwined principles: 1) strengthening student agency, 2) producing diverse but explicit op…
In search of perceptual and acoustical correlates of polyphonic timbre
2009
Polyphonic timbre refers to the overall timbre mixture of a music signal, or in simple words, the 'global sound' of any piece of music. It has been proven to be an important element for computational categorization according to genre, style, mood, and emotions, but its perceptual constituents have been less investigated. The aim of the study is to determine the most salient features of polyphonic timbre perception by investigating the descriptive auditory qualities of music and mapping acoustic features to these descriptors. Descriptors of monophonic timbre taken from previous literature were used as a starting point. Based on three pilot studies, eight scales were chosen for the actual exp…
Transport de la variabilité dans les matériaux composites = Uncertainties propagation in composite materials
2009
National audience; Dans ce travail, une méthodologie de transport d'incertitudes à travers les différentes échelles d'observation des matériaux composites : (i) micro (fibres et matrice), (ii) méso (pli), (iii) macro (matériau stratifié) est proposée. L'objectif est d'intégrer à l'échelle macro (celle du calcul de structure) l'effet des incertitudes venant de l'échelle micro et celle des incertitudes introduites à chacune des échelles méso et macro. La démarche proposée s'appuie sur l'élaboration dès l'échelle micro de distributions statistiques bâties sur l'analyse morphologique et obtenues grâce à la génération de matériaux virtuels.
