Bifurcations in the elementary Desboves family

2017

International audience; We give an example of a family of endomorphisms of $\mathbb{P}^2(\mathbb{C})$ whose Julia set depends continuously on the parameter and whose bifurcation locus has non-empty interior.

Common ragweed national maps & public policies in France

2014

Common ragweed (Ambrosia artemisiifolia L.) has been detected in France in the middle of the XIXth century. It has spread throughout the territory during the XXth century with a critical evolution. Public policies have not been able to contain this spread at the moment, and it is now difficult to find ways to tackle the invasion. Publication of national and regional maps seems to be an effective tool to draw up an overview of the situation and build management strategies. With a set of historical and modern data collected all over the French territory, and from many different stakeholders, we consider the progress of the species in time. The system of legislation applied locally is analyzed…

Models and tools for territorial dynamic studies (chapter 1)

2012

As part of the ArchaeDyn project, a workgroup was formed to coordinate the development, implementation and application of methods and tools for spatial analysis. The workgroup's activities were directed at various problems. The first was to construct a grid common to all the workgroups and to homogenize the study areas used by the different workgroups in their databases. The 'confidence maps' method was suggested for assessing the quality and quantity of information inventoried in the databases. Confidence maps are produced from representation and reliability maps by simple map algebra and they can be considered as 'masks' for interpreting spatial analysis results. Finally, the research tea…

Geostatistical computing of acoustic maps in the presence of barriers

2009

Acoustic maps are the main diagnostic tools used by authorities for addressing the growing problem of urban acoustic contamination. Geostatistics models phenomena with spatial variation, but restricted to homogeneous prediction regions. The presence of barriers such as buildings introduces discontinuities in prediction areas. In this paper we investigate how to incorporate information of a geographical nature into the process of geostatistical prediction. In addition, we study the use of a Cost-Based distance to quantify the correlation between locations.

Discriminating and simulating actions with the associative self-organising map

2015

We propose a system able to represent others’ actions as well as to internally simulate their likely continuation from a partial observation. The approach presented here is the first step towards a more ambitious goal of endowing an artificial agent with the ability to recognise and predict others’ intentions. Our approach is based on the associative self-organising map, a variant of the self-organising map capable of learning to associate its activity with different inputs over time, where inputs are processed observations of others’ actions. We have evaluated our system in two different experimental scenarios obtaining promising results: the system demonstrated an ability to learn discrim…

The Coaching Maps as a Tool for Developing Reflectivity in Organisations

2018

Przyszłość wymaga od ludzi innego spojrzenia na funkcjonowanie organizacji, wykonywang=ą w nich przez ludzi pracę oraz posiadane przez menedżerów kompetencje. świecie ponowoczesności i postfordyzmu gospodarka i organizacje funkcjonują w odmienny sposób ni? w XX wieku. Tym samym innego rodzaju oczekiwania adresowane są do pracowników. Refleksyjność stała się nie tylko jednym z kluczowych zasobów ludzi i organizacji, lecz także przedmiotem kształcenia. Autorzy tekstu, w oparciu o model auto- etnografii i action-research, ukazują autorskie narzędzie do pracy rozwojowej, skierowane do menedżerów i pracowników m.in. w kontekście kreowania i wyzwalania w nich refleksyjności. Etnografia obrazu, fi…

Convergence Analysis of Distributed Set-Valued Information Systems

2016

This paper focuses on the convergence of information in distributed systems of agents communicating over a network. The information on which the convergence is sought is not rep- resented by real numbers, as often in the literature, rather by sets. The dynamics of the evolution of information across the net- work is accordingly described by set-valued iterative maps. While the study of convergence of set-valued iterative maps is highly complex in general, this paper focuses on Boolean maps, which are comprised of arbitrary combinations of unions, intersections, and complements of sets. For these important class of systems, we provide tools to study both global and local convergence. A distr…

Vineyard design supported by GPS application

2021

The innovative technologies of precision agriculture offer nowadays new applications in line with the needs of the wine sector. In hillside viticulture, within the same plot there are areas with different physical and chemical characteristics (lying, pH, active limestone, nutrients, etc.). This variability consequently influences the vigor of the vine which translates into a different production per single plant in terms of both yield and quality of the grapes. The aim of this study was to realize geo-referenced thematic maps by GPS application on a hilly plot covering about 6 hectares to be planted in a hedgerow trained vineyard for the production of quality grapes. The experimental tests …

(Un)exhausted Cartographies. Re-living the visuality, aesthetics and politics in contemporary mapping theories and practices

This thesis is concerned with examining the life and deadliness of the map trope in contemporary Human Geography and the various ways maps and mapping have been re-theorized over the past twenty five years. Arguing that there is presently a feeling of exhaustion and disinterest amongst many human geographers in the use of maps given a shift to postmodern and poststructural approaches that decentre maps and mistrust their supposed objectivity, their representational qualities, and use by institutions to justify certain political actions, it tries to relive the attention in the ubiquity and flourishing of contemporary mapping practices by promoting a re-worked post-representational perspectiv…
