Extraction of thermal characteristics of surrounding geological layers of a geothermal heat exchanger by 3D numerical simulations
2016
Ground thermal conductivity and borehole thermal resistance are key parameters for the design of closed Ground-Source Heat Pump (GSHP) systems. The standard method to determine these parameters is the Thermal Response Test (TRT). This test analyses the ground thermal response to a constant heat power injection or extraction by measuring inlet and outlet temperatures of the fluid at the top of the borehole heat exchanger. These data are commonly evaluated by models considering the ground being homogeneous and isotropic. This approach estimates an effective ground thermal conductivity representing an average of the thermal conductivity of the different layers crossed by perforation. In order …
Digital Storytelling Project as a Way to Engage Students in Twenty-First Century Skills Learning
2020
[EN] This paper is focused on the implications of a collaborative digital storytelling project on student engagement in the higher education context. The empirical study is conducted with an interdisciplinary group of bachelor students in a Nordic University (N = 22) and a university in Southern Europe (N = 21), and the data are collected through an online student survey. The results demonstrate that the digital storytelling project supported students’ behavioral, emotional, and cognitive engagement. In general, the students had positive emotional experiences with the project. This assignment format was found less stressful than a frontal presentation in the classroom, allowing the students…
Forward $J/\psi$ and very backward jet inclusive production at the LHC
2018
In the spirit of Mueller-Navelet dijet production, we propose and study the inclusive production of a forward $J/\psi$ and a very backward jet at the LHC as an observable to reveal high-energy resummation effects \`a la BFKL. We obtain several predictions, which are based on the various mechanisms discussed in the literature to describe the production of the $J/\psi$, namely, NRQCD singlet and octet contributions, and the color evaporation model.
Searches for transverse momentum dependent flow vector fluctuations in Pb-Pb and p-Pb collisions at the LHC
2017
The measurement of azimuthal correlations of charged particles is presented for Pb-Pb collisions at $\sqrt{s_{\rm NN}}=$ 2.76 TeV and p-Pb collisions at $\sqrt{s_{\rm NN}}=$ 5.02 TeV with the ALICE detector at the CERN Large Hadron Collider. These correlations are measured for the second, third and fourth order flow vector in the pseudorapidity region $|��|<0.8$ as a function of centrality and transverse momentum $p_{\rm T}$ using two observables, to search for evidence of $p_{\rm T}$-dependent flow vector fluctuations. For Pb-Pb collisions at 2.76 TeV, the measurements indicate that $p_{\rm T}$-dependent fluctuations are only present for the second order flow vector. Similar results hav…
Orientation of charged clay nanotubes in evaporating droplet meniscus.
2015
© 2014 Elsevier Inc. During drying, an aqueous suspension of strongly charged halloysite clay nanotubes concentrates at the edge of the droplet ("coffee-ring" effect) which provides alignment of the tubes along the liquid-substrate contact line. First, the surface charge of the nanotubes was enhanced by polyanion adsorption inside of the lumen to compensate for the internal positive charges. This increased the magnitude of the ξ-potential of the tubes from -36 to -81mV and stabilized the colloids. Then, colloidal halloysite was dropped onto the substrate, dried at 65°C and after a concentration of ~0.05mgmL-1 was reached, the alignment of nanotubes occurred starting from the droplet edges. …
Multi-objective optimisations for a superscalar architecture with selective value prediction
2012
This work extends an earlier manual design space ex ploration of our developed Selective Load Value Pre diction based superscalar architecture to the L2 unified cache. A fter that we perform an automatic design space expl oration using a special developed software tool by varying several architectural parameters. Our goal is to find optim al configurations in terms of CPI (Cycles per Instruction) and energy consumption. By varying 19 architectural parameter s, as we proposed, the design space is over 2.5 millions of billions configurations which obviously means that only heuristic search can be considered. Therefore, we propose dif ferent methods of automatic design space exploratio n based…
Il concetto cristiano di corporazione in Léon Harmel
2015
«The first modern corporate experiment» was defined by what Pierre Louis Léon Harmel (1829-1915) had achieved in his yarn factory in Val des bois in the town of Warmeriville close to Rheims in the French department of Marne. Harmel was a French Catholic entrepreneur very sensitive to the social issues of his time. Harmel, while he was progressively turning away from the paternalism of his father, although he was nicknamed "le Bon Père", moved along the tracks of the social doctrine of the Church and the principles of social Catholicism, inspired in particular by Œuvre des Cercles by Rene La Tour du Pin and Albert de Mun. He decided to turn his factory in a kind of community where the basic …
Democrazia e corporazione in Léon Harmel
2019
Il nome di Léon Harmel (1829-1915) si può certamente associare alla vicenda storica del cattolicesimo sociale francese dell’Ottocento. Imprenditore e riformatore sociale, Harmel ebbe un ruolo determinante nell’apertura della Chiesa alle problematiche della società moderna. Egli non fu un teorico in senso stretto, né un pensatore politico, bensì un “realizzatore”. Eppure la sua figura e la sua opera merita, a nostro avviso, una specifica attenzione. Sia perché rappresentativo, sul piano della sua stessa biografia personale, di un’epoca di grande transizione intellettuale e sociale, sia perché fu il primo a realizzare nella sua fabbrica laniera in Val des Bois la corporazione cristiana. Sorre…
Fast Image Restoration Algorithms Based on PDE Models Using Modified Hopfield Neural Network
2010
Two image restoration algorithms based on modified Hop field neural network and variational partial differential equations (PDE) were proposed in our previous work [1, 2]. But the convergence rate of the proposed algorithms was slow. In this paper, we develop a fast update rule based on modified Hop field neural network (MHNN) of continuous state change and two fast image restoration algorithms. Experimental results show that, when compared with the previous algorithms, our proposed algorithms have better performance both in convergence rate and in image restoration quality.
