The hunt for infrasound; infrasound detections can be used to locate infrasound sources, such as volcanoes, supersonic jet fighters and (nuclear) explosions

Infrasonic signature of the 2009 major sudden stratospheric warming

The study of infrasound is experiencing a renaissance since it was chosen as a verification technique for the Comprehensive Nuclear-Test-Ban Treaty. The success of the verification technique strongly depends on knowledge of upper atmospheric processes. The ability of infrasound to probe the upper atmosphere starts to be exploited, taking the...

The inaudible symphony: On the detection and source identification of atmospheric infrasound

Sound becomes inaudible if it consists of frequencies lower than 20 Hz, i.e. the human hearing threshold, and is called infrasound. Low frequency acoustic signals were first discovered after the eruption of the Krakatoa (Indonesia) in 1883. Due to its low frequency content, this infrasound traveled up to seven times around the globe while...

Real-time hiring of vehicles for container transport

This study concerns the deployment of large numbers of container transporting vehicles on a network consisting of (dedicated) roads and logistic sites such as container terminals. Each site is managed autonomously by a site manager. The fleet of vehicles is deployed by a fleet manager. On request of the site managers, the fleet manager allocates...

Improving travel-time reliability by the use of trip booking

Transfer station and method for loading and/or unloading containers from a ship

Containers are transported with at least one quay crane (10) from and/or to a ship (14) along a quay (19). The quay crane (10) has a hoisting range comprising a first vehicle-positioning strip (26) on a quay surface. Depending on whether other vehicles (16, 17) are present or not on the positioning strips, vehicles (16, 17) are instructed to...

Road-rail vehicle

A transport vehicle equipped with a number of first wheel sets, having wheels provided with tires, to which steering means and driving means, if any, are coupled to enable the transport vehicle to be moved over a road surface. The transport vehicle further comprises at least one second wheel set, having rail wheels, which rail wheels can be...
