  The CERGOP Project of the Central European Countries initiated six GPS observation campaigns from 1994 to 2001. By the high standards set within this project for site selection, observation and analysis a consistent set of epoch solutions with a precision in the 3–5 mm range was created. The network contains about 19 permanent and 38 epoch stations. In this paper a first combination solution over the seven years with a velocity...

• Velocity Field Characteristics at the Inlet to a Pipe Culvert

  Publikacja

  • P. Wielgat

  - Archives of Hydro-Engineering and Environmental Mechanics - Rok 2014

  A poorly designed culvert inlet structure causes scouring, which can lead to the collapse of the culvert and significant damage to the neighboring land. A set of laboratory tests was evaluated to examine velocity distribution at the culvert inlet. A three-dimensional acoustic Doppler velocimeterwas used to measure instantaneous flowvelocity upstream of the culvert. The analysis of mean velocities, turbulence strength, and Reynolds...

• The field–dependent interface recombination velocity for organic–inorganic heterojunction

  Publikacja

  • J. Szmytkowski

  - CHEMICAL PHYSICS LETTERS - Rok 2016

  We have derived an analytical formula which describes the field–dependent interface recombination velocity for the boundary of two materials characterized by different permittivities. The interface recombination of charge carriers has been considered in the presence of image force Schottky barrier. We suggest that this effect may play an important role in the loss of current for organic–inorganic hybrid heterojunctions. It has...

• Method of reconstructing two-dimensional velocity fields on the basis of temperature field values measured with a thermal imaging camera

  Publikacja

  • K. Tesch
  • M. Ryms
  • W. Lewandowski

  - INTERNATIONAL JOURNAL OF HEAT AND MASS TRANSFER - Rok 2022

  This paper describes a novel numerical reconstruction procedure (NRP) of the velocity field during natural convective heat transfer from a two-sided, isothermal, heated vertical plate based only on the known temperature field obtained, e.g. with a thermal imaging camera. It has been demonstrated that with a knowledge of temperature distributions, the NRP enables the reconstruction of velocity fields by solving the Navier-Stokes...

  - Acta Geodynamica et Geomaterialia - Rok 2012

  Presently the determination of the velocity field in the global reference frame is possible by using different space techniques and dense terrestrial networks from global to local and regional scales. However, the reliability of such determinations is strongly limited by the restricted number of unmodeled effects. Some of them are periodic (atmospheric or hydrological effects), some instantaneous (natural or man-made seismicity)...

  • J. Bogusz
  • P. Kamiński

  - Acta Geodynamica et Geomaterialia - Rok 2010

  The paper concerns analysis of solutions obtained during common processing of data from GNSS permanent stations situated on mountainous terrain: the Western Carpathians, the Sudetes Mountains and adjacent areas. As the outcome daily and weekly solutions (ellipsoidal coordinates) of forty Polish, Czech, Slovak, Ukrainian and German sites were obtained. Weekly solutions were used to determine velocity field and vertical movements,...
