1. Nickel–titanium instruments in endodontics: a concise review of the state of the art
Abstract: The introduction of automated instrumentation in endodontics represented a major advance in progress for this specialty, with improvements in the quality and predictability of root canal preparation and a significant reduction in procedural errors. In recent years, endodontic instruments have undergone a series of changes brought about by modificat

2. A Comparative Study of Four Feedback Linearization Schemes for Motion Planning of Fixed-Wing Unmanned Aerial Vehicles
ABSTRACT In this paper, different feedback linearization schemes are studied to address the motion planning problem of fixed-wing unmanned aerial vehicles. For a unmanned aerial vehicle model with second-order dynamics, several schemes are studied to make the vehicle (i) fly over and (ii) make a loitering around the objective position. For each scheme, compa

3. Global optimal path planning of an autonomous vehicle for overtaking a moving obstacle
In this paper, the global optimal path planning of an autonomous vehicle for overtaking a moving obstacle is proposed. In this study, the autonomous vehicle overtakes a moving vehicle by performing a double lane-change maneuver after detecting it in a proper distance ahead. The optimal path of vehicle for performing the lane-change maneuver is generated by a

4. Doenças osteomusculares e articulares em idosos atendidos em um centro de reabilitação de um hospital universitário: descrição da prevalência e do perfil demográfico e de saúde
Population aging has been leading to the increase in chronic degenerative disorders, among them musculoskeletal and joint diseases (MJD), of which low back pain is among the most prevalent and symptomatic in the elderly. The MJDs result in functional disabilities that negatively impact on the independence and quality of life of the elderly. Hence, profile de

5. Planejamento periódico de trajetórias de sistemas afins sem arrasto em grupos de Lie compactos / Periodic motion planning of trajectories for control-affine driftless systems in compact Lie groups
We treat the periodic motion planning problem: given a periodic trajectory of a control-affine driftless system in a compact and connected Lie group G and an initial condition in G, find another trajectory of the same system satisfying the initial condition given and that asymptotically tracks the periodic trajectory. We solve this problem locally (for initi

6. Cinemática da marcha de crianças com desenvolvimento típico e com paralisia cerebral diplégica espástica nível I e II do GMFCS: um estudo comparativo
The objective of the study is compare, using PCA, the kinematics of the pelvis, hip, knee and ankle during gait between typical and spastic diplegic cerebral palsy GMFCS I and II children. Cross-sectional observational study was realized with 56 children, aged 6 to 12 years (9.0±SD), divided into three groups: children level I of the GMFCS; children level I

7. Planejamento de movimento cinemático-dinâmico para robôs móveis com rodas deslizantes / Motion planning for kinematic-dynamic mobile robots with wheels sliding
O planejamento de movimento é um dos problemas fundamentais em navegação autônoma para robôs móveis. Uma vez planejado o caminho, o robô executa o acompanhamento da trajetória, frequentemente, com o auxílio de um controlador em malha fechada. Este controlador tem o objetivo de minimizar os erros de acompanhamento, a fim de que a trajetória executad

8. 3DS-BVP : a path planner for arbitrary surfaces / 3DS-BVP: um planejador de caminhos para superfícies arbitrárias
Métodos eficientes para planejamento de caminhos têm sido explorados ao longo dos anos para permitir movimento de robôs autônomos ou agentes virtuais. Basicamente, estes algoritmos buscam pelo ambiente por um caminho com pouca probabilidade de colisão com obstáculos, e que conduza o agente de uma posição inicial para uma posição objetivo. Apesar de

9. Hybrid motion planning approach for robot dexterous hands
This paper presents a manipulation planning approach for robot hands that enables the generation of finger trajectories. The planner is based on a hybrid approach that combines discrete-continuous kinematics using a fully discrete transition system. One of the main contributions of this work consists in the representation of the universe of different submode

10. Comportamento de líquidos no espaço-sloshing e amortecedores de nutação viscosos / Fluid behavior in the space-sloshing and viscous nutation dampers
The attitude dynamics refers to the space vehicle motion around its center of mass while orbiting the Earth. The knowledge of the attitude motion is fundamental for the accomplishment of the space mission objectives. The use of appropriate sensors and actuators, onboard computers, GPS and radars and ground stations are among technologies allowing the attitud

12. Trajectory planning of jumping over obstacles for hopping robot
Trajectory planning strategy is proposed to jump over an obstacle integrated three various dynamics in one-legged multi-joint hopping robot. A concept of inertia matching ellipsoid and directional manipulability are extended to optimize take-off postures. Optimized results have been used to plan hopping trajectory. Aimed at the sensitivity of motion trajecto
