In this paper, we present a robust closed-loop gait for the Nao, the humanoid robot used in the RoboCup Standard Platform League. The active balancing used in the approach is based on the pose of the torso of the robot, the estimation of which we also describe. In addition, we present an analytical solution to the inverse kinematics of the Nao, solving the problems introduced by the special hip...

In this article, we apply the independent component analysis technique for mining spatio-temporal data. The technique has been applied to mine for patterns in weather data using the North Atlantic Oscillation (NAO) as a specific example. We find that the strongest independent components match the observed synoptic weather patterns corresponding to the NAO. We also validate our results by matchi...

To improve fishery management, there is an increasing need to understand the long-term consequences of natural and anthropogenic climate variability for ecological systems. New England's iconic cod populations have been in decline for several decades and have recently reached unprecedented lows. We find that 17% of the overall decline in Gulf of Maine cod biomass since 1980 can be attributed to...

The authors build on their efforts to understand and predict coastal hurricane activity by developing statistical seasonal forecast models that can be used operationally. The modeling strategy uses May–June averaged values representing the North Atlantic Oscillation (NAO), the Southern Oscillation index (SOI), and the Atlantic multidecadal oscillation to predict the probabilities of observing U...

Positive feedback between high-frequency eddies and low-frequency processes is believed to play an essential role in the NAO evolution. In this study, however, it found that previously well-studied upscale forcing intraseasonal scale window mostly limited during phase NAO−, but almost disappears NAO+. The maintenance of NAO+ by a strong barotropic instability basic flow, which has been overlook...

The role of natural factors mainly solar eleven-year cycle variability, and volcanic eruptions on two major modes of climate variability the North Atlantic Oscillation (NAO) and El Niño Southern Oscillation (ENSO) are studied for around last 150 years period. The NAO is the primary factor to regulate Central England Temperature (CET) during winter throughout the period, though NAO is impacted d...

IMPORTANCE Clinical management of nasal airway obstruction (NAO) in patients with and without nasal allergic symptoms and nasal valve collapse (NVC). OBJECTIVE To examine the impact that autologous alar batten grafts have on patients with NAO owing to NVC and their affect on nasal steroid use and allergic symptoms. DESIGN A prospective study. SETTING Indiana University Medical Center, Ind...

Team BreDoBrothers participated in the Nao Standard Platform League (Nao SPL) of Robocup 2008 in Suzhou. 2008 being the first year that the Nao SPL was hold every team had the same starting position regarding to the new robot Nao, being the new two legged robot platform designed and produced by Aldebaran Robotics. Team BreDoBrothers was the best team after the preliminary rounds being the only ...
