In railway systems, wear-induced wheel flats (out-of-roundness wheel shape) are among the most common local surface defects. They reduce the train ride comfort, increase fatigue risk and raise safety concerns. A good knowledge of wheel flats (presence and ...
The interactions with touchscreens rely heavily on vision: The virtual buttons and virtual sliders on a touchscreen provide no mechanical sense of the object they seek to represent. This work presents PopTouch: a 500 mu m thick flexible haptic display that ...
The present invention relates to a motor-wheel for an omni-directional motion vehicle, comprising a ring-shaped structure with a central axis, presenting an outer radial surface and an inner radial surface, whereby the outer radial surface comprises a plur ...
In a granulometric material, there can be three different types of instabilities: by vibrations, by shearing or by gravity action. Washboard effect appears when a car is rolling on an unpaved road (made of sand, gravel or mud). It creates waves that are un ...
Driving is a very challenging task to automatize despite how naturally and efficiently it may come to experienced human drivers. The complexity stems from the need to (i) understand the surrounding context and forecast how it is likely to evolve, (ii) plan ...
An implantable delivery device for delivering a fluid in a controlled manner, including a body having a chamber, a tube having an inlet and an outlet, at least a portion of the tube passing through the chamber, a drive pinion operatively connected to a mot ...
Train wheel flats are formed when wheels slip on rails. Crucial for passenger comfort and the safe operation of train systems, early detection and quantification of wheel-flat severity without interrupting railway operations is a desirable and challenging ...
The effects of friction are critical to the dynamics of electric power steering (EPS). On the one hand, friction contributes to the stability of the system and filters some of the disturbances (road vibration, etc.). On the other hand, it affects negativel ...
A large portion of the visual cortex is organized retinotopically, but perception is usually non-retinotopic. For example, a reflector on the spoke of a bicycle wheel appears to move on a circular or prolate cycloidal orbit as the bicycle moves forward, wh ...
The success of seedlings and rejuvenated woody debris growing on river bedforms depends on the resistance to uprooting by flow provided by their simple root architecture. Avena sativa and Medicago sativa seedlings were used in flume experiments as prototyp ...
