Jackknifing refers to the serious situation where a vehicle-trailer system enters jackknife state and vehicle trailer eventually collide if operation is not corrected. This paper considers low speed maneuvering typical of backing. Jackknife limits can vary due sideslip caused by physical interaction between vehicle, trailer, environment. Analysis kinematic model at wheels. Results indicate that...

In dependency parsing, jackknifing taggers is indiscriminately used as a simple adaptation strategy. Here, we empirically evaluate when and how (not) to use jackknifing in parsing. On 26 languages, we reveal a preference that conflicts with, and surpasses the ubiquitous ten-folding. We show no clear benefits of tagging the training data in cross-lingual parsing.

Tractor-trailer vehicles are affected by jackknifing, a phenomenon that consists in the divergence of trailer hitch angle and ultimately causes vehicle to fold up. For case backward motions, which jackknifing can occur at any speed, we present control method drives along generic reference Cartesian trajectories while avoiding angle. This is obtained thanks feedback law combines two actions: tra...
