Thermoelectric radiation detector based on a superconductor-ferromagnet junction : Calorimetric regime

2018

We study the use of a thermoelectric junction as a thermal radiation detector in the calorimetric regime, where single radiation bursts can be separated in time domain. We focus especially on the case of a large thermoelectric figure of merit ZT affecting significantly, for example, the relevant thermal time scales. This work is motivated by the use of hybrid superconductor/ferromagnet systems in creating an unprecedentedly high low-temperature ZT even exceeding unity. Besides constructing a very general noise model which takes into account cross correlations between charge and heat noise, we show how the detector signal can be efficiently multiplexed by the use of resonant LC circuits givi…

Field dependence of the vortex-core sizes in dirty two-band superconductors

2019

We study the structure of Abrikosov vortices in two-band superconductors for different external magnetic fields and different parameters of the bands. The vortex core size determined by the coherence lengths are found to have qualitatively different behaviour from that determined by the quasiparticle density of states spatial variation. These different vortex core length scales coincide near the upper critical field, while the discrepancy between them becomes quite significant at lower fields. Within the diffusive approximation we demonstrate several generic regimes in the field dependence of the vortex core sizes determined by the disparity of diffusion constants in the two bands.

Evoluzione tipologica e tecnologica dei sistemi di abitazione per l'emergenza _ Typological and technological evolution of housing systems for emerge…

2017

Le tipologie di abitazione temporanea oggi utilizzate in caso di emergenza si possono ricondurre a due sistemi strutturali fondamentali: il sistema ad involucro flessibile ed il sistema ad involucro rigido. Da questi deriva un sistema misto in cui elementi flessibili si integrano ad elementi rigidi, generando soluzioni particolarmente interessanti sia dal punto di vista tecnologico sia formale. Ai sistemi flessibili appartiene la tenda, insieme a tutte quelle strutture leggere, estensibili e/o gonfiabili, quali strutture a pantografo, pneumatiche o, tensostruttu-re. Ai sistemi rigidi si fa risalire la casa, da cui derivano il container ed il prefab-bricato, ma anche la roulotte ed il camper…

Les outils d'intelligence territoriale pour les acteurs de terrain à Seraing: entre appropriation des méthodes et acquisition de compétences

2005

Asbl Optim@ leads an experience of participative observation in Seraing since 1998. The complexity of the problems met by the population and the professional division into sectors justified this participative approach. This one concerns the economic, social and human global nature of the territory. It leans on a wide partnership of local actors: professionals, inhabitants and decision-makers. It uses at this end the method of territorial intelligence CATALYSE created by the research team ThéMA-MTI and developed with numerous members of the REIT. The results obtained in terms of interdisciplinary dialogue between inhabitants, professionals and decision-makers; allow identifying axes about th…

What Can You Achieve in Eight Years? : A Case Study on Participation, Effectiveness, and Overall Impact of a Comprehensive Workplace Health Promotion…

2019

Objective: To investigate participation and effectiveness of a multiyear comprehensive workplace health promotion (WHP) program. Methods: Participation and effectiveness data came from employer and vendor systems. Health data came from health risk assessments (HRA) and biometric screenings. Participation and effectiveness were analyzed using descriptive analyses, T-tests and Mann-Whitney U tests where appropriate. Overall impact was assessed using the PIPE Impact Metric. Results: 86% of employees completed the HRA and 80% the biometrical screenings. Annual participation rate was 24%, and total reach was 58%. The portion of successful participants was 23% in 2010–2013 and 18% in 2014–2017. P…

Etenemisnopeudet ja sykkeet eritasoisilla suunnistajilla käyttäen satelliittipaikannusta

2006

Juha Nivukoski: Etenemisnopeudet ja sykkeet eritasoisilla suunnistajilla käyttäen satelliittipaikannusta. Liikuntafysiologian Pro gradu -tutkielma. Jyväskylän yliopisto. Liikuntabiologian laitos. Satelliitteihin perustuva GPS-paikannus (Global Positioning System) ja sen sovellukset ovat yleistyneet 2000-luvulla monilla eri elämänalueilla. Liikuntatieteissä laitteen antamia mahdollisuuksia on tutkittu hyvin vähän, koska GPS:n tarkkuuteen ja soveltuvuuteen suhtaudutaan vielä epäröiden. Tässä tutkimuksessa selvitettiin kevyen kannettavan GPS-laitteen soveltuvuutta ulkona tapahtuvan urheilusuorituksen analysointiin sekä GPS-laitteen antaman paikkatiedon perusteella selvitettiin koehenkilöiden k…

Introduction: The Pedagogical Obstacle of the Phenomenal Forms

2016

This book is a further development from a previous one, published only in Spanish, whose title can be translated as The Copernican turn and the social sciences (Villacanas de Castro, 2013). It was a philosophical work relating to a general epistemological problem lying at the heart of the social and natural sciences. On the other hand, the present volume is firmly rooted in pedagogy. This difference reflects the professional journey that I have made in the meantime, from being a Graduate Student at a Faculty of Philosophy to becoming a member of staff at a Faculty of Education, where I currently lecture and carry out research. Despite the various shifts brought about by this transition, an …

Optimal control of the Schrödinger equation with two or three levels

2007

In this paper, we present how techniques of “control theory”, “sub-Riemannian geometry” and “singular Riemannian geometry” can be applied to some classical problems of quantum mechanics and yield improvements to some previous results.

Solving Conflicts among Conservation, Economic, and Social Objectives in Boreal Production Forest Landscapes: Fennoscandian Perspectives

2018

This chapter discusses challenges and possibilities involved in preserving biological diversity and the diversity of ecosystem services in the boreal zone and yet at the same time maintaining intensive timber extraction in boreal forests. Our focus is on Fennoscandian forests at the landscapes level, and we consider economic, social and ecological in the sustainability of forest management. We provide an outlook to boreal forest ecosystems and their history, and an overview of the forestry practices and policies that aim to ensure multi-functionality of Fennoscandian forests, i.e. diversity of efforts on sustaining biodiversity, timber production and other ecosystem services from forest lan…
