Sediment-flow interactions and effects on bed forms mechanism
2009
Recent experimental works conducted in mobile bed rectilinear flume seem to verify the existence of a correspondence between the spatial periodicity of horizontal turbulent structures evolving in streamwise direction and the wavelength of bed forms (alternate bars) observed on the bed. In this study, the effect of the variation of the bed roughness conditions on the evolution of such horizontal turbulent structures is analyzed. Peculiar results obtained by using flow velocity data collected along the flume both with flat bed and with deformed bed are reported.
Impacts écologiques des formes d'urbanisation : modélisations urbaines et paysagères
2015
The global increase of urbanization during the past decades have induced a progressive artificialization of natural environments. The building of transport infrastructures and new housings causes a landscape fragmentation in an irreversible way and a strong decrease of the connectivity of ecological habitats. Maintaining the functionality of ecological networks is becoming a major goal of sustainable urban planning policies. With a special focus on urban evolutions in the horizon 2030 in the urban area of Besançon in eastern France (residential development and road traffic evolutions), this thesis aims to assess the potential impact of urban forms on landscape connectivity of animal species…
A normative planning approach for the Luxembourg : assessment based on spatial simulation
2015
In Luxembourg, daily mobility patterns of both cross-border workers and residents lead to a strong car dependance. This process encourages urban sprawl. Meanwhile the country is faced to increasing housing needs but has to reduce land consumption. Within this context, the main objective of this thesis is to throw light about the relation between residential growth patterns and daily mobility behaviors. In this way, a normative planning approach has been adopted. This approach proposes new planning norms for achieving a series of planning objectives. Quantitative rules are the tools used to apply the norms.Three steps has been done: i) conception of residential growth scenarios for 2030. By …
Sensitivity of a climate model to urban form : application on Dijon Métropole
2020
The urban environment is at the crossroads of two complex systems with different temporalities : climate and society. The urban climate is a modification of the climate caused by the presence of a city. The most successful expression of this climate change by the presence of the city is the phenomenon of Urban Heat Island (UHI). In a global context of adaptation and mitigation to climate change and urban development, this phenomenon of ICU tends to increase, and its health impacts on populations to become more prominent. This work is aimed at improving the knowledge of the impact of urban form and urban development on the intensity of the UCI through the implementation of a decision support…
Laika-aspekta formu lietojums filmu recenzijās
2020
Recenzijas ir žanrs filmu producēšanas jomā un liels skaits recenziju katrai jaunajai filmai ir atrodams vairākos medijos un tiešsaistes platformās. Ir tikuši veikti pētījumi par stilistiskajiem aspektiem, kas veido filmu recenzijas interneta laikmetā. Gramatisko pētījumu trūkums filmu recenzijās veicina turpmākus pētījumus šajā jomā. Tādēļ, šī pētījuma mērķis ir pētīt laika-aspekta formu biežumu un pielietojumu tiešsaistes filmu recenzijās. Lai sasniegtu mērķi, tika izmantotas divas pētnieciskās metodes biežuma analīze un diskursa analīze. Analīzes apkopotie dati atklāja, ka visbiežāk izmantotās laika-aspekta formas tiešsaistes filmu recenzijās bija vienkāršā tagadne un vienkāršā pagātne, …
Weed communities in conservation agriculture: what really changes?
2022
Conservation agriculture (CA) has been identified as one of the farming systems likely to deliver sustainable agriculture but its effects over time on the diversity and composition of weed communities are still discussed. For ten years, different studies were carried out in in East of France in cropping system with short rotations essentially composed with winter crops. The objective of these different studies was to identify, focusing on the transition period, the changes in the composition of communities and the consequences in terms of agronomic risk in CA systems. Using networks of 100 winter wheat fields selected to encompass a gradient of years in CA (1 to 20 years), the changes that …

Postmodernity: clinical and social reflections about new forms of psychopathology
2016
International audience; This article proposes a reflection on the impact that some postmodern features can have on the sense of identity and on mental functioning to propose possible explanations for identity changes and new forms of psychopathology. After revisiting the most recent literature on the theme, this study proposes a clinical consideration for a possible link between new forms of psychopathology and mental suffering. It particularly suggests that the changes observed in affectivity (including increase in dysphoria, irritability, restlessness, boredom, feeling of emptiness) and behaviour (reduction in impulse control ability, in interpersonal skills and reflective function, etc.)…
