Optimum design of speed control humps for vehicles.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1988 This paper deals with optimum design problems of humps for controlling vehicle speeds. Optimum humps are obtained for a segment of a circle in section using a method with a SUMT optimizing a hump for a vehicle. The objective of the design is to minimize the maximum acceleration of the driver occurring during a vehicle crossing a hump at a design speed ...

The Effect of Speed Humps on Highways Pavement Condition [PDF]
International Journal of Engineering, 2020 Speed humps used as a tool of traffic calming technique that applied to force drivers to reduce their vehicle’ speeds at some locations. For developed countries, the implementations of speed humps are often used within residential areas as well as at locations of schools crossing. For developing countries (e.g.

Sharp Diamond Needles for Single‐Photon Emission
Advanced Photonics Research, EarlyView.We study the morphological evolution of single‐crystal diamond needles oxidized at 650–700 °C. Electron microscopy and photoluminescence reveal temperature‐ and time‐dependent sharpening, length reduction, and surface modifications affecting tip properties.

Advanced Science, EarlyView.A predictive model for 3D printability is developed by integrating rheological analysis, including the Large Amplitude Oscillatory Shear (LAOS) test, with machine learning. With prediction errors under 10%, the model shows that post‐extrusion recovery controls horizontal printability, while high‐strain‐rate nozzle flow dictates vertical printability ...

Distance between speed humps and pedestrian crossings: Does it matter?
Accident Analysis & Prevention, 2011 Speed humps are a common physical measure installed at pedestrian crossings to reduce vehicle speeds therefore improve the safety and mobility of pedestrians at the crossing. The aim of this study was to determine whether variations in distance between speed humps and pedestrian crossings contribute differently to the safety and mobility of pedestrians
