Besançon at the decolonization time : the decolonization process studied a medium-sized French ciy from 1945 to the 1960s

2016

This doctoral thesis aims at assessing the impact of the decolonisation process on the population of Besançon. The study of an urban community involves taking an interest in various historiographical fields (such as the political and cultural history of both colonisation and decolonisation, as well as the Cold War). From a people's history perspective, our purpose is to grasp how people experienced decolonisation (how they understood, felt, thought, acted). This research covers the period from 1945 up to the 1960s. A two-angled approach has been applied, including comparisons on local and national levels and a thorough investigation of Besançon's social environment in and of itself. The div…

Conception et synthèse de nouvelles sondes fluorogéniques à coeur Bodipy pour la détection

2020

Therefore this project is aimed at the development of novel improved multi-analyte fluorogenic probes for heavy metals ions and bioanalytes within the framework “AND” fluorescent molecular logic gates concept. The biothiols and cations of Cd(II), Pb(II), Cr(III) and Cu(II) heavy metals will be selected as the targeted analytes. To the best of our knowledge, no “AND” molecular logic gates using metal ions besides Zn(II), Hg(II), Ca(II) inputs, likewise no multi-analyte probes for biothiols along with heavy metal cations, has been described in the literature. While the development of a highly sensitive and selective recognition of thiols and metal cations has emerged as a significant interest…

Hausdorff measures, Hölder continuous maps and self-similar fractals

1993

Let f: A → ℝn be Hölder continuous with exponent α, 0 < α ≼ 1, where A ⊂ ℝm has finite m-dimensional Lebesgue measure. Then, as is easy to see and well-known, the s-dimensional Hausdorif measure HS(fA) is finite for s = m/α. Many fractal-type sets fA also have positive Hs measure. This is so for example if m = 1 and f is a natural parametrization of the Koch snow flake curve in ℝ2. Then s = log 4/log 3 and α = log 3/log 4. In this paper we study the question of what s-dimensional sets in can intersect some image fA in a set of positive Hs measure where A ⊂ ℝm and f: A → ℝn is (m/s)-Hölder continuous. In Theorem 3·3 we give a general density result for such Holder surfacesfA which implies…

A Lebesgue-type decomposition for non-positive sesquilinear forms

2018

A Lebesgue-type decomposition of a (non necessarily non-negative) sesquilinear form with respect to a non-negative one is studied. This decomposition consists of a sum of three parts: two are dominated by an absolutely continuous form and a singular non-negative one, respectively, and the latter is majorized by the product of an absolutely continuous and a singular non-negative forms. The Lebesgue decomposition of a complex measure is given as application.

On the Coincidence of the Feedback Nash and Stackelberg Equilibria in Economic Applications of Differential Games

2002

In this paper the scope of the applicability of the Stackelberg equilibrium concept in differential games is investigated. Firstly, conditions for obtaining the coincidence between the Stackelberg and Nash equilibria are defined in terms of the instantaneous pay-off function and the state equation of the game. Secondly, it is showed that for a class of differential games with state-interdependence both equilibria are identical independently of the player being the leader of the game. A survey of different economic models shows that this coincidence is going to occur for a good number of economic applications of differential games. This result appears because of the continuous-time setting i…

Population Games with Vector Payoff and Approachability

2016

This paper studies population games with vector payoffs. It provides a new perspective on approachability based on mean-field game theory. The model involves a Hamilton-Jacobi-Bellman equation which describes the best-response of every player given the population distribution and an advection equation, capturing the macroscopic evolution of average payoffs if every player plays its best response.

The scientific payload on-board the HERMES-TP and HERMES-SP CubeSat missions

2021

HERMES (High Energy Rapid Modular Ensemble of Satellites) Technological and Scientific pathfinder is a space borne mission based on a LEO constellation of nano-satellites. The 3U CubeSat buses host new miniaturized detectors to probe the temporal emission of bright high-energy transients such as Gamma-Ray Bursts (GRBs). Fast transient localization, in a field of view of several steradians and with arcmin-level accuracy, is gained by comparing time delays among the same event detection epochs occurred on at least 3 nano-satellites. With a launch date in 2022, HERMES transient monitoring represents a keystone capability to complement the next generation of gravitational wave experiments. In t…

CSCL for NGO's Cross cultural Virtual Teams in Africa: An Ethiopian Children Advocacy Case Study against Exclusion and toward Facilitation of Express…

2005

This exploratory pilot study shows that NGO's involved in Children Advocacy through Arts in Africa are willing to use a groupware, meaning a computer supported collaborative learning (CSCL) environment. Innovative ideas and best practices among NGOs would be shared easily worldwide. Little scientific information is available to help them make a sound choice. This study suggests that some NGOs based in Ethiopia/Africa have specific needs which should translate in specific context analysis and interface development: 1) an intercultural approach to creativity, arts and innovation, and 2) emphasis should be placed on tools to facilitate asynchronous systematic conception and sharing of intra an…

Aalto-1, multi-payload CubeSat: Design, integration and launch

2021

The design, integration, testing, and launch of the first Finnish satellite Aalto-1 is briefly presented in this paper. Aalto-1, a three-unit CubeSat, launched into Sun-synchronous polar orbit at an altitude of approximately 500 km, is operational since June 2017. It carries three experimental payloads: Aalto Spectral Imager (AaSI), Radiation Monitor (RADMON), and Electrostatic Plasma Brake (EPB). AaSI is a hyperspectral imager in visible and near-infrared (NIR) wavelength bands, RADMON is an energetic particle detector and EPB is a de-orbiting technology demonstration payload. The platform was designed to accommodate multiple payloads while ensuring sufficient data, power, radio, mechanica…
