Odeseizar la educación y la cooperación para el desarrollo en España : una mirada internacional a la AOD y al ODS 4
2020
El presente artículo pretende centrar su atención en la política sectorial de la AOD vinculada a la educación desde la ingeniería cosmopolita de los Objetivos de Desarrollo Sostenible que han permitido odeseizarlas políticas mundiales (Barandiarán, 2017), de las que la cooperación y la educación constituyen dos objetos de análisis e investigación. Para ello, sus objetivos se centrarán en revisar el caso español del binomio AOD y educación y cómo, estrechamente vinculado a la ortodoxia política mundial homogeneizadora que proviene de manera intencionalmente manifiesta por parte de los organismos internacionales, la AOD en la actualidad y en este ámbito específico se ha canalizado y transmuta…

Les influences des caractéristiques de l'offre d'éducation sur l'organisation du temps des élèves
1984
International audience; Pour assurer son éducation, un élève mobilise son « intelligence », est influencé par son milieu familial et social, et utilise les services fournis par le système éducatif. Cependant, le niveau de sa réussite scolaire dépendra aussi du temps qu'il affectera au travail scolaire en dehors des cours. Cet article tente de répondre à deux questions : Comment s'organisent les décisions des élèves en matière d'affectation du temps au travail scolaire ? De quelles manières le système éducatif (l'offre d'éducation) contraint-il les arbitrages temps de l'élève ?Les résultats empiriques utilisés sont issus d'une enquête auprès de 650 élèves des collèges.

Fault Diagnostics for Electrically Operated Pitch Systems in Offshore Wind Turbines
2016
This paper investigates the electrically operated pitch systems of offshore wind turbines for online condition monitoring and health assessment. The current signature based fault diagnostics is developed for electrically operated pitch systems using model-based approach. The electrical motor faults are firstly modelled based on modified winding function theory and then, current signature analysis is performed to detect the faults. Further, in order to verify the fault diagnostics capabilities in realistic conditions, the operating profiles are obtained from FAST simulation of offshore wind turbines in various wind conditions. In this way, the applicability of current signature analysis for …
A Two-Stage Fault Detection and Classification Scheme for Electrical Pitch Drives in Offshore Wind Farms Using Support Vector Machine
2019
Pitch systems are one of the components with the most frequent failure in wind turbines. This paper presents a two-stage fault detection and classification scheme for electric motor drives in wind turbine pitch systems. The presented approach is suitable for application in offshore wind farms with electric pitch systems driven by induction motors as well as permanent magnet synchronous motors. The adopted strategy utilizes three-phase motor current sensing at the pitch drives for fault detection and only when a fault condition is detected at this stage, features extracted from the current signals are transmitted to a support vector machine classifier located centrally to the wind farm. The …
Evaluation of performance and efficiency and type approval of an electrically assisted bicycle drive
2013
The diffusion of electrically assisted bicycles gives rise to the need of the evaluation of the performance and efficiency of the electric drive that supply it. In this paper, is presented a test bench for the estimation of the electric drive output torque under several speed and load conditions. Moreover, the test bench detects the electrical and mechanical parameters that allow to evaluate the electrical drive efficiencies. The test bench has been designed in agreement with the Directive 2002/24/EC of the European Parliament since it detects the maximum continuous rated power (that must be lower than 0.25 kW) and evaluates if the output is progressively reduced and finally cut off as the …
High cognitive sensitivity to activational effects of testosterone in parents of offspring with autism spectrum disorders
2014
Abstract The existence of mild forms of autistic-like characteristics in parents of children with autism spectrum disorders (ASDs) has been defined as a broader autistic phenotype (BAP). Excessive prenatal exposure to testosterone (T) seems to play a role in its development. The aims of this study were to characterize whether ASD parents show masculinized brains or high T prenatal exposure compared to a normative population, using cognitive questionnaires, and also to examine the T level changes in response to different cognitive tasks. ASD parents were found to present higher autistic and lower empathic trait scores than controls. They also have higher T levels and magnitude of T response …
High order normal form construction near the elliptic orbit of the Sitnikov problem
2011
We consider the Sitnikov problem; from the equations of motion we derive the approximate Hamiltonian flow. Then, we introduce suitable action–angle variables in order to construct a high order normal form of the Hamiltonian. We introduce Birkhoff Cartesian coordinates near the elliptic orbit and we analyze the behavior of the remainder of the normal form. Finally, we derive a kind of local stability estimate in the vicinity of the periodic orbit for exponentially long times using the normal form up to 40th order in Cartesian coordinates.
Evidence for a teratogenic risk in the offspring of health personnel exposed to ionizing radiation?!
2016
Background The evidence concerning safety of occupational exposure to ionizing radiation on teratogenic effects mainly relies on animal models, disaster epidemiology and experience in cancer etiology. Following an explorative result on maternal exposure in medical occupations we conducted a feasibility study, addressing congenital anomalies (CA) in the offspring of health workers potentially exposed to radiation. Methods In a prospective follow-up study, we enrolled women, identified by mandatory registration at the office of radiation protection as wearing a dosimeter. The participating women answered a questionnaire and if pregnant agreed to an examination of their infant. CA were diagnos…
