DE 19855175 C UPAB: 20000718 NOVELTY - The mounting device or pig (1) fits inside the pipeline and may be moved along it. The pig has a flat front (1a) face with three swivels carrying e.g. hydraulic piston and cylinder units (2) whose other ends are connected together ...

New buildings, as well as the renovated building stock, should aim not just for good energy performance but also for good quality of the works, as this is a prerequisite for high building energy performance. Various experiences show that there are cases where the qualit...

This paper describes currents induced in a network of thin conducting rods. The transfer functions of these currents were calculated with the NEC-2 code and compared with measurements on the same structure in our tri-plate transmission-line simulator. Comparison shows f...

Optimizing painting facilities and processes by numerical simulations based on computational fluid dynamics. It is shown how to save energy, perform efficient planning and to find solutions for problems in the factories.

Almost always it is emphasized in the literature that the input-output map of a BIBO-stable (bounded input-bounded output) linear and time invariant systems (LTI-systems) is given by the well known convolution sum. It was discovered that not all discrete-time single-inp...

In a fixed bed reactor (1) comprising a receiving container (2) and a permeable carrier medium (21) loaded by the substrate to be cleaned, said carrier medium (21) being for the purpose of settlement by bacteria, a swell chamber (11) vertically permeated by the carrier ...

Over the last years, the synthesis and characterization of new spinel-type gallium oxonitrides were in the focus of several working groups. Our systematic investigation of the formation of the gallium oxonitride spinel phases was done under different experimental condit...

Indoor humidity is an important factor for human health, well-being or damage like mold growth. Excessive indoor humidity conditions may be caused by non-adequate ventilation or temporarily due to change of temperature in rooms. The moisture buffering effect of linings ...
