The Fish Funnel: A Trawl Modification to Reduce Fish Escapement [PDF]
In the Gulf of Mexico there is a need to assess the potential of underutilized fish resource stocks before a commercial fishery develops. Standard sampling trawls used in the Gulf are ineffective for sampling the resource, so larger, high opening, bottom

Optimum design of speed control humps for vehicles.
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]
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
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.
