On shunting over a hump
We consider the situation of rearranging freight trains in a shunting yard with a hump and several tracks. Here, an elementary shunting operation is to push a all cars of one track over the hump. On the way back to the tracks the cars can be guided individually to an arbitrary track. The goal is to create one or several trains that have their cars in a particular order. We measure the efficienc...
متن کاملThe mid-level hump at 2 kHza)
Shortening the duration of a Gaussian-shaped 2-kHz tone-pip causes the intensity-difference limen !DL" to depart from the ‘‘near-miss to Weber’s law’’ and swell into a mid-level hump #Nizami et al., J. Acoust. Soc. Am. 110, 2505–2515 !2001"$. For some subjects the size of this hump approaches or exceeds the size reported for longer tones under forward masking, suggesting that forward masking mi...
متن کاملThe Rib Hump in Idiopathic Scoliosis
This paper describes a simple method for the recording of rib deformity in idiopathic scoliosis. The relationships have been recorded between the measured rib hump and rib depression deformities and I) the rotation of the vertebral bodies (as measured by the method of Nash and Moe on the standing radiograph); 2) the degree of lateral curvature (as measured by the method of Cobb on the standing ...
متن کاملHysteresis Characteristic in Hump Region of a Pump-Turbine Model
The hump characteristic is one of the major instabilities in pump-turbines. When pumpturbines operate in the hump region, strong noise and serious fluctuations could be observed, which are harmful to the safe and stable operations and even destroy the whole unit as well as water conveyance system. In this paper, a low specific speed (nq = 36.1 min−1) pump-turbine model was experimentally invest...
متن کاملVibration Reduction Using Multi-Hump Extra-Insensitive Input Shapers
Input shaping is a method for reducing residual vibrations in computer controlled machines. Vibration is eliminated by convolving an input shaper, which is a sequence of impulses, with a desired system command to produce a shaped input. The shaped input then becomes the command to the system. Requiring the vibration reduction to be insensitive to modeling errors and system nonlinearities is cri...
