Extension des méthodes de géométrie algorithmique aux structures fractales

2013

Defining shapes by iteration allows us to generate new structures with specific properties (roughness,lacunarity), which cannot be achieved with classic modelling.For developing an iterative modeller to design fractals described by a BCIFS, we developed a set oftools and algorithms that permits one to evaluate, to characterize and to analyse different geometricproperties (localisation, convex hull, volume, fractal dimension) of fractals. We identified properties ofstandard CAD operations (intersection, union, offset, . . . ) allowing us to approximate them for fractalsand also to optimize these approximation algorithms.In some cases, it is possible to construct a CIFS with generalised HUTCH…

Characterisation of mechanical behavior of a sub surface drilled polymer, under hertzian contact load

2013

This research concerns the understanding of the sub-surface behaviour of a component presenting controlled heterogeneities and subjected to a Hertzian type load. The purpose is to qualify the stress field in the subsurface. Practically, defects of cylindrical shape are located where the stress field is maximal in sub surface. The contact is sized to be able to observe, by photoelasticity, the stress field and to develop a numerical model to simulate the behaviour (static and dynamic) of the friction area. It is highlighted that the presence of a hole on the z axis of symmetry (x = 0) is the dominating factor. The characteristics which allow decreasing the shearing stress on the symmetry axi…

Optimal control and applications to orbital transfer and almost-riemannian geometry

2010

In this thesis we focus on optimal control techniques as well as geometric control techniques applied to the orbital transfer problem and to almost-Riemannian geometry. In these cases, Pontryagin’s Maximum Principle allows to analyse the extremal flow of affine control systems.In the case of a satellite with low-thrust propulsion, averaging techniques give an approximated system. Averaging is explicit in the energy minimization case and is directly related to almost-riemannian problems. The geometric analysis of such problems is generalized by the study of metrics on the two-sphere of revolution. In this way it is possible to classify the situations considering the transcendance of the solu…

Effect of a Service-Learning Program on the Active Lifestyle of Children with Autism Spectrum Disorder: A Pilot Study

2020

Background: active lifestyles and Physical Activity (PA) are closely related to health. Healthy habits such as being physically active should be consolidated during childhood. Children with Autism Spectrum Disorders (ASD) present fewer opportunities to be involved in PA. For this reason, we conducted a Service-Learning (SL) program to enhance the possibility of participating ASD children enjoying PA sessions. The aim of this study was to analyze and describe the evolution in terms of the frequency and intensity of PA performed by ASD children who participated in the SL program. Methods: we used a quasi-experimental design. The sample was formed by 26 children with ASD (Experimental group: n…

Introduction. The value of accessibility in the cultural and creative industries: Translation-driven settings

2020

This study focuses on the relationship between translation, accessibility and the cultural creative industries, as well as on the different varieties of genres included in these industries as cultures of accessibility. The accessibility of CCI has grown exponentially in different parts of the globe and has increasingly become part of projects of significant importance in contemporary societies that rely on informational, global, and networked systems of communication, i.e., developed countries. CCI exist within public-domain areas and are stimulated by the critical rethinking of the means which can be used to support cultural development. CCI are in fact driven by structures of the knowledg…

Alexithymia as a Predictor of Arousal and Affect Dysregulations when Batterers with Attention Deficit Hyperactivity Disorder Cope with Acute Stress

2020

Empirical research has stated that Attention Deficit Hyperactivity Disorder (ADHD) might underlie intimate partner violence against women (IPVAW) perpetration. Even though there is a clear relationship between these two variables, it is still unknown how ADHD facilitates violence proneness. In this regard, psychophysiological variables such as skin conductance levels (SCL) might offer information about emotional regulation when individuals cope with stress. Furthermore, alexithymia traits might be a strong candidate in explaining the above-mentioned emotional dysregulations. Hence, we compared the SCL response to acute cognitive stress in IPVAW perpetrators with and without ADHD symptoms to…

Sustainability Assessment of Agricultural Systems in Paraguay: A Comparative Study Using FAO’s SAFA Framework

2019

Sustainability is a topic that is at the center of current discussions in the political, economic, social, and environmental fields. For its analysis, an integral and multidisciplinary vision is needed. This work aims to assess the sustainability of agricultural systems in Paraguay through a comparison applying SAFA (Sustainability Assessment of Food and Agriculture Systems) indicators. The research focuses on 15 case studies on the territory of the Eastern Region of Paraguay divided into five classes of agricultural systems: agribusiness, conventional peasant family farming, agroecological peasant family farming, neo-rural farming, and indigenous agriculture. Data were collected through in…

The importance of social value in agroecological farms: adjusting the common good balance sheet to improve their sustainable management

2021

Organic farming offers the producers the possibility of focusing on their business while obtaining a competitive advantage. Nevertheless, this is centered in specific activities of the production process, thus only creating environmental value. Therefore, it is not an approach based on sustainability. As a consequence of this, it becomes necessary to enlarge this approach toward people (social value) and profitability (economic value). The objective of this work is to describe a tool based on the Economy for the Common Good model applied to the agroecological sector. We propose to adapt the Common Good Matrix to the characteristics of agroecological farms to offer a useful tool to manage an…
