1. Prediction of 3D ground reaction forces during gait based on accelerometer data
Abstract Introduction The aim of this study was to predict 3D ground reaction force signals based on accelerometer data during gait, using a feed-forward neural network (MLP). Methods Seventeen healthy subjects were instructed to walk at a self-selected speed with a 3D accelerometer attached to the distal and anterior part of the shank. A force plate was

2. The inertial effect of acceleration fields on a self-decoupled wheel force transducer
AbstractWheel force transducer (WFT) is a tool which can measure the three-axis forces and three-axis torques applied to the wheel in vehicle testing applications. However, the transducer is generally mounted on the wheel of a moving vehicle, when abruptly accelerating or braking, the mass/inertia of the transducer itself has extra effects on the sensor resp

3. A crise financeira de 2008: os discursos e as estratégias do governo e dos fundos de pensão
This article focuses on the financial crisis beginning in 2008. Drawing on the work of Lebaron (2010; 2011) and (Grün 2010), the study seeks to grasp the "cognitive dimension" of the crisis through the discourses produced (and reproduced) by members of the Brazilian government involved in controlling the crisis and by the pension fund sector and its strateg

4. Nonlinear dynamics of electromagnetic pulses in cold relativistic plasmas
In the present analysis we study the self-consistent propagation of nonlinear electromagnetic pulses in a one-dimensional relativistic electron–ion plasma, from the perspective of nonlinear dynamics. We show how a series of Hamiltonian bifurcations give rise to the electric fields which are of relevance in the subject of particle acceleration. Connections

5. As possibilidades subjetivas da prática esportiva / The Subjective possibilites of the sport practice
This study aimed to investigate the subjective possibilities of the sport practice: Race Street in the city of Fortaleza, Ceara, Brazil. It also attempted to identify the directions shown by the subjects and to describe the satisfactory aspects of this sport. Faced with the studied phenomenon, it is observed that there are subjective possibilities considered

6. Formação de professores em nível médio na modalidade a distância : a experiência do Proformação
The development of public policies to the formation of teachers at work is a challenge to education in the XXI century in Brazil. The present thesis was built by starting off with the analysis of a Ministry of Education program which provided the formation in high school mainstream modality to teachers who are teaching the first years of the elementary level

7. Agente topológico de aprendizado por reforço / Topological reinforcement learning agent
Reinforcement Learning (RL) methods have shown to be a good choice for decision-making problems due to their flexible and adaptive characteristics. Despite such promising features, RL methods often have their practical application restricted to small or medium size (at state, or state-action, space) problems mainly because of their standard strategies for va

9. Laser production of highly charged ions
A summary of ion generation experiments at both low (10(9) W=cm²) and high (10(16) W=cm²) laser intensities, using Nd:YAG and iodine lasers, as well as the properties of the ions produced, are presented. Different medium- and high-Z elements were tested as a target: Ag, Al, Au, Co, Cu, Nb, Ni, Pb, Pt, Sn, Ta, W. A maximum charge state 55+ and maximum energ

11. Modelos Efetivos para o Elétron / Effective Models for the Electron
We present two models for the electron in classical electrodynamics, which include some effects from quantum electrodynamics. In the first model, the electron is treated as an extended particle owing to the high-frequency oscillations (Zitterbewegung) of its electrical charge. We show that this model predicts correctly the magnitude of the electron spin and

12. Imagem de si em crianças com histórico de fracasso escolar a luz da teoria de Henri Wallon
This study s objective was to investigate how the child who has been failed in school built his/her self image and which reality s aspects he/she use to do so. Texts written by those 10 years old children who participated of an learning acceleration program were analyzed. The analysis was based on: Henri Wallon s psicogenetic theory related to the self image
