• Local variance factors in deformation analysis of non-homogenous monitoring networks

  Publikacja

  • W. Kamiński
  • K. Nowel

  - SURVEY REVIEW - Rok 2013

  This paper proposes a modification of the classical deformation analysis algorithm for non-homogeneous (e.g. linear-angular) monitoring networks. The basis for the proposed solution is the idea of local variance factors. The theoretical discussion was complemented with an example of its application on a simulated horizontal monitoring network. The obtained results confirm the usefulness of the proposed solution.

  - Geodesy and Cartography - Rok 2013

  This paper proposes a modification of the classical process for evaluating the statistical significance of displacements in the case of heterogeneous (e.g. linear-angular) control networks established to deformation measurements and analysis. The basis for the proposed solution is the idea of local variance factors. The theoretical discussion was complemented with an example of its application on a simulated horizontal control...

• Assessing the Significance of Displacements Using Local Coefficients of Variance as an Alternative to the Classical Approach

  Publikacja

  • D. Filipiak-Kowszyk
  • W. Kamiński
  • K. Makowska-Jarosik

  - Rok 2018

  The safety of use of civil engineering structures remains an important issue that is approached by various sciences. Due to this fact, geodetic control measurements are conducted with the purpose of identifying threats connected with the potential displacement of structural elements. In this context, the authors discuss issues connected with determining the displacements of controlled points located in the studied object in a three-dimensional...

• DETERMINATION OF VERTICAL DISPLACEMENTS IN RELATIVE MONITORING NETWORKS

  Publikacja

  • D. Filipiak-Kowszyk
  • W. Kamiński

  - Archives of Civil Engineering - Rok 2020

  The problem of determining displacements of objects is an important and current issue, in particular in terms of operational safety. This is a requirement that covers geodetic, periodic control measurements in order to determine horizontal and vertical displacements. The paper is focused on the analysis of vertical displacements. Geodetic measurements and their interpretation allow to reduce the risk of possible structural catastrophes....

• ON EGNOS MONITORING IN LOCAL CONDITIONS

  Publikacja

  • A. Felski
  • A. Nowak

  - Artificial Satellites, Journal of Planetary Geodesy - Rok 2013

  Any SBAS system should deliver to the user corrections to pseudoranges as well as information about the system integrity. In theory, as soon as the system is permanently monitored by RIMS stations, it is impossible to deliver the fault information to the user. However many observations shows that accuracy of EGNOS service in the same time are different in different places, which shows the influence of local conditions on them....

• A Non-local elasto-plastic model to describe localisations of deformation in concrete

  Publikacja

  • J. Bobiński
  • J. Tejchman

  - TASK Quarterly - Rok 2002

  Przedstawiono wyniki numerycznej symulacji lokalizacji odkształceń stosując metodę elementów skończonych na bazie nielokalnego prawa sprężysto-plastycznego dla betonu. Prawo wykorzystuje długość charakterystyczną. Obliczenia dla ściskania jednoosiowego pokazały, że wyniki numeryczne nie zależą od siatki MES. Osiągnięto pełną regularyzację problemu brzegowego.

• DiSTFAG method robust to gross errors in monitoring displacements and strains in unstable reference systems

  Publikacja

  • W. Kamiński

  - Geodesy and Cartography - Rok 2011

  The DiSTFA method (Displacements and Strains using Transformation and Free Adjustment) was presented in Kamiński (2009). The method has been developed for the determination of displacements and strains of engineering objects in unstable reference systems, as well as for examining the stability of reference points. The DiSTFAG (Gross errors) method presented in the paper is the extension of the DiSTFA method making it robust to...
