This paper proposes a novel algorithm for humanoid robots to walk on unknown uneven terrain by using the Modifiable Walking Pattern Generator (MWPG). The proposed algorithm runs with a finite state machine including ascending and descending states. If the landing time of a swinging leg on unknown uneven terrain is shorter than the assigned single support time, the state is switched to the ascen...

Most classical preclinical tests to predict antidepressant activity were initially developed to detect compounds that influenced noradrenergic and/or serotonergic activity, in accordance with the monoaminergic hypothesis of depression. However, central opioid systems are also known to influence the pathophysiology of depression. While the tail suspension test (TST) is very sensitive to several ...

2014 The Lagrangian L03BC (r, 03B8) = 1/2(1 + 03BC)r2 + 1 2r203B82r(03BC cos 03B8) with 1 03BC ~ 3.1 is studied using a surface of section map. Regular and chaotic behaviour is exhibited. The numerical evidence suggests the motion is integrable for 03BC = 3. Integrability is proved by explicitly exhibiting a first integral. J.

A normal Atwood Machine is composed of two masses connected with a string, hanging from pulleys, (see figure 1). This system is often used to teach Newton’s laws of motion due to its simplicity. However, it is not very interesting to study beyond that. When the two masses are not equal, the heavier one will accelerate down and the other will accelerate up at the same rate. When the masses are e...
