<title>Pilot clinical evaluation of prototype system for visually reporting the results of ultrasound examination</title>
2000
A dedicated optic-mechanical device, attachable to an ultrasound scanner, has been developed that allows visual documenting of ultrasound examination by recording multiple gray-scale images, i.e. ultrasound tomography (UST), to be performed routinely and at low cost. The device is operated by one hand without interrupting the examination. Each page of UST report is composed by deliberate positioning multiple images within the 2X4 framework and recorded on a 35-mm microfilm. If necessary, graphic reconstructions were composed from standard graphic components and interposed between the original images on the same frame. UST report is communicated to a patient and/or a referring doctor on a co…
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.
Flexible power converters for the fault tolerant operation of Micro-Grids
2010
The progressive penetration level of Distributed Generation (DG) is destined to cause deep changes in the existing distribution networks no longer considered as passive terminations of the whole electrical system. A possible solution is the realization of small networks, namely the Micro-Grids, reproducing in themselves the structure of the main production and distribution of the electrical energy system. In order to gain an adequate reliability level of the microgrids the individuation and the management of the faults with the goal of maintaining the micro-grid operation (fault tolerant operation) is quite important. In the present paper flexible power converters and a companion control al…
Large-Eddy Simulation of Turbulent Flow in an Unbaffled Stirred Tank Driven by a Rushton Turbine
2005
The turbulent flow fieldgeneratedin an unbaffledstirredtank by a Rushton turbine was computedby large-eddy simulation (LES). The Smagorinsky model was used to model the unresolved, or sub-grid, scales. A general purpose CFD code was appropriately modified in order to allow the computation of the sub-gridviscosity andto perform statistics on the computedresults. The numerical predictions were comparedwith the literature results for comparable configurations andwith experimental data obtainedusing particle image velocimetry. A very goodagreement was foundas regards both time-averagedresolv edfield s andturb ulence quantities. 2004 Elsevier Ltd. All rights reserved.
How can organisations and business models lead to a more sustainable society? A framework from a systematic review of the industry 4.0
2019
The concept of Industry 4.0 has been mainly addressed by the current literature from a technological perspective, overlooking the organisational and even ethical challenges related to this recent paradigm. In order to become &lsquo
Balancing ‘flexibility’ and ‘employability’: The changing role of general studies in the Finnish and Swedish VET curricula of the 1990s and 2010s
2019
This article analyses and compares the evolving role of general subjects in the curricula of initial upper secondary vocational education and training (VET) in Finland and Sweden during the 1990s and 2010s. The research illustrates how Bernstein’s concept of ‘pedagogic code’ supports comparative studies on principles guiding changes to curricula and how the role of general studies in VET has been redefined. The findings show that while a principle of ‘market relevance’ has been central to VET over the decades since the 1990s, it has been subject to varying interpretations. The shifts in interpretations have guided the organisation of VET in these two countries in different directions, incl…
Ethical Entrepreneurship Training. Theoretical Reflection and Case Analysis
2014
Abstract In this paper we first reflect on the theoretical foundation of ethical entrepreneurship training in the field of economy. In this sense, we try to establish briefly the theoretical and historical assumptions of ethical entrepreneurship, especially from a review of the work of Adam Smith, professor of Moral Philosophy and central figure in the birth of the modern economy. We then present a definition of entrepreneurial activity, which is closely linked to a social and ethical dimension of economy and to the internal goods of economic activity. On the basis of these considerations, we propose some objectives of training for ethical entrepreneurship. Finally, we present a case study …
Developing a Pedagogical Framework and Design Principles for STEM Learning Environment Design
2020
The need for effective and attractive learning environments (LEs) for science, technology, engineering, and mathematics (STEM) has been internationally recognized. Additionally, the connection between STEM learning and cross-curricular skills such as creativity, innovation, and entrepreneurship has garnered attention. A deep theoretical and empirical understanding is required when designing STEM LEs. In this study, a pedagogical framework for STEM LEs has been developed based on feedback from students, aged 10–18 years old, teachers, school directors, parents, and STEM professionals, and supported by the literature. First, representatives of key stakeholder groups in Belarus, Finland, Germa…
Sub specie æternitatis: the role of the ruin and the ancient in the process of architectural renewal between metamorphosis and resurgence
2022
Composing new works of architecture inspired by vestiges from antiquity or archaeology. The reflections and the case study which will be proposed, pertaining to a recent design experiment for the archaeological area and Antiquarium of Tyndaris, are dedicated to this theme. Over and above any charm exerted by such places, by landscapes in which the ruins appear identical in substance and which sometimes manifest themselves as “sub specie æternitatis”, there are reasons linked to the very profession of architect and to the gashes in the crucible of controversies around the role of history in its contentious relationship with architectural design. That apart, the aporias revealed by Michel Fou…
An optimal dimensioning method of a green wall structure for noise pollution reduction
2021
International audience; This paper concern the optimization of a multilayered green wall structure including substrate and foliage in order to reduce as much as possible backward noise reflection and forward transmission from the wall. Each component involved in the wall structure is fully characterized experimentally to get its transfer matrix. Simulation demonstrated that foliage layer superimposed to substrate layer doesn’t affect the transmission losses but contributes greatly to the increase of return losses of the green wall structure. To achieve the best performances in terms of return and forward losses as well as frequency bandwidth, the methods of optimization are discussed inclu…
