In this paper, we propose a control system that changes the compliance based on the walking speed to stabilize biped walking on rough terrain. The proposed system does not use the inclination of the terrain. Instead, the system changes walking modes depends on its walking speed. In the downhill terrain, when the walking speed is increased, the stiffness of(More)
Since the introduction of ventriculo-atrial and/or ventriculo-peritoneal shunting for hydrocephalic patients, controversies have developed regarding the likelihood of epileptic seizures developing as a result of the shunting itself and/or its complications. On the other hand, hydrocephalus is not commonly recognized as a cause of seizures in general,(More)
We present here the structure of our humanoid robot soccer team JEAP. We use a heterogenous set of commercial humanoid robots that are havily customized from their original design. For this RoboCup we are also ordering a new custo m designed humanoid whose specifications are already included in this paper. The task of controlling these robots is faced(More)

A 65-year-old man suffering from acute pancreatitis underwent MRI scanning, which revealed a low signal on the T1 and T2 sequences, and hypovascularity in arterial phase in the head of the pancreas. This corresponded to the area showing the absence of the lower common bile duct. FDG-PET was highly suggestive of pancreatic cancer (T4N1M0, Stage IVa) with(More)
