Collision Avoidance with Potential Fields Based on Parallel Processing of 3D-Point Cloud Data on the GPU
2014
In this paper we present an experimental study on real-time collision avoidance with potential fields that are based on 3D point cloud data and processed on the Graphics Processing Unit (GPU). The virtual forces from the potential fields serve two purposes. First, they are used for changing the reference trajectory. Second they are projected to and applied on torque control level for generating according nullspace behavior together with a Cartesian impedance main control loop. The GPU algorithm creates a map representation that is quickly accessible. In addition, outliers and the robot structure are efficiently removed from the data, and the resolution of the representation can be easily ad…

Monotone generalized nonlinear contractions and fixed point theorems in ordered metric spaces
2011
The purpose of this paper is to present some fixed point theorems for T -weakly isotone increasing mappings which satisfy a generalized nonlinear contractive condition in complete ordered metric spaces. As application, we establish an existence theorem for a solution of some integral equations.
Verso una geografia per la partecipazione
2018
This article introduces the contributions collected in the special issue no. 1/2018 of “geotema” and presented at the 4th Study Day on Territorial Identities (Rome, September 22nd, 2017), promoted by the homonymous research group of the A.Ge.I. (Associations of Italian Geographers). The paper aims at discussing some basic questions on participatory processes, in order to pursue four objectives: 1) to recall some of the main issues that revolve around the topic of citizen participation in territorial decision-making processes; 2) to specify the ties between territorial identity (as intended by the research group) and participatory processes; 3) to highlight the questions raised by the contri…
USING THE ENVIRONMENTAL MANAGEMENT SYSTEM (EMS) TO CONTROL THE IMPLEMENTATION AND EMERGENCE OF GREEN STRATEGIES.
2009
To respond to the ecological challenges of the new century and their Environmental and Social Responsability, more and more companies adopt the Environmental Management System (EMS). The objective of this thesis is to analyze how this management system is used in French companies for implement their ''intended" green strategies and to explore the new green strategies. To answer this problematic, we mobilized two theoretical frameworks during this research: the New Institutionalism in Organizational Analysis (DiMaggio and Powell, 1983, 1991 and Hasselbladh Kallinikos, 2000) and Levers of control model (Simons, 1995). Then, our research methodology is composed of three phases succeeding: an e…
Compromiso Estudiantil en el Contexto Universitario Colombiano y Desempeño Académico
2014
20 páginas A pesar de la ampliación de la cobertura en la educación superior latinoamericana, persisten graves problemas de deserción que llevan a cuestionar el papel de las experiencias educativas en el fomento del compromiso académico de los estudiantes. Esta investigación se realizó en Colombia y buscó determinar la relación que existe entre el compromiso estudiantil y el desempeño académico de un grupo de universitarios colombianos. El estudio transversal y correlacional empleó la versión en español de la encuesta National Survey of Student Engagement (NSSE) que mide el nivel de participación de los estudiantes en cinco dimensiones: reto académico, aprendizaje activo y colaborativo, int…

Uso de redes sociales online en personas mayores de 55 años : un análisis exploratorio
2012
Es una aproximación cualitativa al uso y percepción que tienen los mayores de 55 años, de las tecnologías de la comunicación e información (TIC); Concretamente del uso de las redes sociales online. Mediante la técnica de los grupos de discusión trataremos de buscar los prejuicios, mitos conocimientos, motivaciones, barreras, etc. del uso o no de las redes sociales online. It is a qualitative approach to the use and perception of over 55 years of technology and information communication technology (ICT), specifically the use of online social networks. By the technique of focus groups will try to find the prejudices, myths, knowledge, motivations, barriers, etc.. use or not online social netw…
Yhtenäisyyttä rakentava peruskoulu – yhtenäisen perusopetuksen ehdot ja mahdollisuudet
2007
Koulu ja perusopetus ovat toiveiden, vaateiden ja odotusten myllerryskenttä. Koulun ja perusopetuksen kehittäminen on myös keskeinen tulevaisuuden haasteisiin vastaamisen keino. Lapselle ja nuorelle koulu näyttäytyy puolestaan arkisina kohtaamisina, joissa vertaisryhmän ja aikuisten maailma lomittuu ja usein myös törmää toisiinsa. Tässä teoksessa raportoitu tutkimus on tarttunut uusimpaan suomalaisen peruskoulun uudistukseen: yhtenäisen perusopetuksen kehittämiseen. Yhtenäistä perusopetusta tarkastellaan kirjassa koulun kehittämisen pedagogisena ja yhteisöllisenä haasteena. Tutkimushankkeen tarkoituksena on ollut ymmärrettävän kuvan luominen suomalaista perusopetusta päivittäin toteuttavist…
