homogeneous embeddings of SL2(C) modulo a finite sub-group.
2000
L'objet de ce travail est l'étude des variétés algébriques normales complexes munies d'une action algébrique de $SL_{2}$ et qui contiennent $SL_{2}/H$ comme orbite ouverte, $H$ étant un sous-groupe fini de $SL_{2}$.Plus précisément on définit un plongement homogène de $SL_{2}/H$ comme la donnée d'une $SL_{2}$-variété irréductible $X$ (quasi-projective ou non) contenant $SL_{2}/H$ comme orbite ouverte et d'un morphisme $SL_{2}$-équivariant de $SL_{2}$ dans $X$.Les plongements homogènes lisses ainsi que les plongements minimaux (plongements lisses et complets qui ne sont pas des éclatements d'un autre plongement lisse complet) de $SL_{2}/\{Id\}$ et de $SL_{2}/\{\pm Id\}$ ont été déterminés pa…

Towards a Real-time Mitigation of High Temperature while Drilling using a Multi-agent System
2018
International audience; In oilfield wells, while drilling for several kilometers below surface, high temperature damages the drilling tools. This costs money and time for tripping operations to change the damaged tool. Existing temperature mitigation techniques have several drawbacks including a long response time, analogue signal issues and human intervention. In this work, we empower the down-hole tools with a coordination mechanism to mitigate high temperature in soft real time by controlling a down-hole actuator through a voting process. The tools are represented by agents that control the sensors and actuators embedded in these tools. To implement the proposed system properly, a model …
An immunologist's guide to immunosenescence and its treatment
2022
Abstract Introduction: Aging causes several changes in the immune system, although immune aging is strongly influenced by individual immunological history, as well as genetic and environmental factors leading to inter-individual variability. Areas covered: We focused on the biological and clinical meaning of immunosenescence. SARS-CoV-2 and Yellow Fever vaccine have demonstrated the clinical relevance of immunosenescence, while inconsistent results, obtained from longitudinal studies aimed at looking for immune risk phenotypes, have revealed that immunosenescence is highly context-dependent. Large projects allowed the delineation of the drivers of immune system variance, including genetic a…
Information Systems Architecture and Technology: Proceedings of 38th International Conference on Information Systems Architecture and Technology – IS…
2018
This three-volume set of books presents advances in the development of concepts and techniques in the area of new technologies and contemporary information system architectures. It guides readers through solving specific research and analytical problems to obtain useful knowledge and business value from the data. Each chapter provides an analysis of a specific technical problem, followed by the numerical analysis, simulation and implementation of the solution to the problem. The books constitute the refereed proceedings of the 2017 38th International Conference “Information Systems Architecture and Technology,” or ISAT 2017, held on September 17–19, 2017 in Szklarska Poręba, Poland. The con…
The European External Action Service: Torn apart between several principals or acting as a smart 'double-agent'?
2014
Published version of an article in the journal: Journal of Contemporary European Research. Also available from the publisher at: http://www.jcer.net/index.php/jcer/article/view/605/494 Open Access The European External Action Service (EEAS) is a hybrid and compound institutional actor in the EU’s multi-level administration with delegated authority from the member states (MS) to conduct the EU’s external action. Substantial competences, notably in the field of Neighbourhood and Trade policies, as well as Development and Cooperation remain under the control of the European Commission (Commission). At the same time, also Members of the European Parliament (EP) are more clearly voicing their in…
Are you a Good Employee or Simply a Good Guy? Infl?uence Costs and Contract Design.
2012
We develop a principal-agent model with a moral hazard problem in which the principal has access to a hard signal (the level of output) and a soft signal (the supervision signal) about the agent?s level of effort. We show that the agent?'s ability to manipulate the soft signal increases the cost of implementing the effcient equilibrium, leading to wage compression when the infl?uence cost is privately incurred by the agent. When manipulation activities negatively affect the agent?s productivity through the level of output, the design of infl?uence-free contracts that deter manipulation may lead to high-powered incentives. This result implies that high-productivity workers face incentive sch…
Towards a Great Design of Conceptual Modelling
2020
Humankind faces a most crucial mission; we must endeavour, on a global scale, to restore and improve our natural and social environments. This is a big challenge for global information systems development and for their modelling. In this paper, we discuss on different aspects of conceptual modelling in global environmental context. The paper is the summary of the panel session “The Future of Conceptual Modelling” in the 29th International Conference on Information Modelling and Knowledge Bases. peerReviewed

Matemaattisten taitojen kehitys kouluiässä
2018
Matemaattisten taitojen kehitys on luonteeltaan kasaantuvaa: aikaisempi osaaminen helpottaa uuden oppimista ja tasoerot matematiikan taidoissa lasten välillä kasvavat koulunkäynnin edetessä. Matematiikan osalta alkuopetus näyttäisikin hyödyttävän eniten taidoiltaan edistyneimpiä lapsia – taitotasoltaan heikommat lapset jäävät samalla jälkeen. Kehityskulkuun vaikuttavat monet erilaiset tekijät, joista yksi keskeisimmistä on lukujen luettelun sujuvuus ennen kouluikää. Myös motivaatiolla on oma merkityksensä matemaattisten taitojen oppimisessa. Tässä luvussa käsitellään matemaattisten taitojen kehitystä esiopetus- ja kouluvuosien aikana sekä kognitiivisia ja motivaatioon liittyviä asioita, jot…
