In this paper, analysis for reducing lateral forces is implemented by using a railway vehicle model on a sharp curved track. Also, in order to minimize some problems when a railway vehicle runs on a sharp curved track, an active-steering bogie system is investigated. An active steering bogie system of a railway vehicle is designed to alleviate contact forces and to decrease wear of wheel/rail i...

Wheel wear has been a concern in the railway for several decades. Studying the form change of the wheel/rail contacts in particular railways consisting of sharp curves helps to identify the risk of severe or catastrophic wear to minimize maintenance costs in order to be competitive in the transportation business. In this paper, the wheel/rail contact was studied on the particular railways. The ...

Among the visual preferences that guide many everyday activities and decisions, from consumer choices to social judgment, preference for curved over sharp-angled contours is commonly thought to have played an adaptive role throughout human evolution, favoring the avoidance of potentially harmful objects. However, because nonhuman primates also exhibit preferences for certain visual qualities, i...

Previous studies have shown that people prefer objects with curved contours over objects with sharp contours. However, those studies used stimuli that were mainly neutral in emotional valence. We tested here the interplay between visual features and general valence as positive or negative. After replicating curvature preferences for neutral objects, we used positive (cake, chocolate) and negati...

Hair transplantation involving patients with tightly curled Afro-textured hair using follicular unit extraction (FUE) employing conventional rotary punches frequently leads to unacceptably high transection rates. These patients are unsuitable candidates for FUE hair transplantation. Transection rates were observed during FUE in a case series of 18 patients with tightly curled Afro-textured hair...

We prove almost sharp mixed-norm estimates for the X-ray transform restricted to lines whose directions lie on certain well-curved two dimensional manifolds.

Symmetry and contour take part in shaping visual preference. However, less is known about their combined contribution to We examined the hedonic tone preference triggered by interaction of symmetry contour. Symmetric/curved, symmetric/sharp-angled, asymmetric/curved, asymmetric/sharp-angled stimuli were presented an implicit explicit task. The task consisted affective stimulus–response compatib...

We consider planar curved strictly convex domains with no or very weak smoothness assumptions and prove sharp bounds for square-functions associated to the lattice point discrepancy.
