Abstract: A method includes obtaining information about a next upstream burst transmission. The method also includes determining a set of settings based on the information. The method includes adjusting a physical medium dependent (PMD) module based on the set of settings prior to receiving the next upstream burst transmission.

Abstract: A method for determining the viscosity of a medium using a Coriolis mass flow meter comprises exciting bending vibrations in the measuring tube in a symmetrical bending vibration use mode using an exciter arranged symmetrically in relation to a longitudinal direction of the measuring tube; detecting sensor signals of a central vibration sensor also arranged symmetrically in relation to a longitudinal direction of the measuring tube; detecting sensor signals of a vibration sensor on the inlet side and of a vibration sensor on the outlet side; determining a phase relation or time delay between the sensor signals of the central vibration sensor and a symmetrical function of the sensor signals on the inlet-side and outlet-side vibration sensors; and determining the viscosity of the medium as a function of the phase relation or time delay.

Abstract: Arrangement for covering the surface, which may be inclined, of loose material, in particular earth or waste dump material, comprising a sealing course which is provided with a top fill. In order to improve the adhesion between the sealing course and the top fill, a rough layer is arranged on the sealing course, on top of the rough layer an adhesive non-woven fabric, which cooperates with the rough layer in an adhesive manner, and on top of the non-woven fabric a retaining mat, which bonds with the top fill. The adhesive non-woven fabric and the retaining mat may be a known geotextile drainage layer which, when reversed, is used for a standard drainage arrangement.

Abstract: In an operating dump, intermediate sealing layers which are provided with a drainage layer are applied for the production of a multibarrier system to prevent the penetration of seepage water, the seepage water which is collected in the drainage layer being removed and fed to a disposal system. Plastic films or sheets overlapping in the form of roofing tiles or laid as webs have proved suitable as an intermediate covering.
