Cylindricity measurement by the V-block method – Theoretical and practical problems
- S. Adamczak, D. Janecki, K. Stępień
- Mathematics
- 2011
Abstract The most popular methods applied to measure cylindricity are the radial methods. These methods are characterized by a high metrological level. The disadvantage, however, is that they can be… Expand
Qualitative and quantitative evaluation of the accuracy of the V-block method of cylindricity measurements
- S. Adamczak, D. Janecki, K. Stępień
- Engineering
- 1 July 2010
Abstract In various branches of industry (for example, in the paper, electric or shipping industry), large and heavy cylindrical elements play a very important role. Such elements should be of high… Expand
A two-dimensional isotropic spline filter
- D. Janecki
- Mathematics
- 1 October 2013
Abstract The work deals with the development of a two-dimensional isotropic spline filter with application to the separation of components of the surface topography, i.e. roughness, waviness and… Expand
A Preliminary Study of the Coupling of Desorption Electrospray Ionization—Mass Spectrometry with Pressurized Planar Electrochromatography
- D. Janecki, Allyson L. Novotny, S. D. Woodward, J. Wiseman, D. Nurok
- Chemistry
- JPC – Journal of Planar Chromatography – Modern…
- 1 February 2008
This report describes the first results from coupling of pressurized planar electrochromatography (PPEC) and desorption electrospray ionization (DESI) mass spectrometry (MS). Nine analytes were… Expand
The catenation and isomerisation effects on stability constants of complexes formed by some diprotic acids.

- 30 June 2000
Stability constants (K(ijk)) of complexes Na(i)K(j)H(k)L(+i+j+k-2) (0<i+j+k</=2) formed by dicarboxylic (oxalic, malonic, succinic, glutaric, adipic and methylmalonic, dimethylmalonic, ethylmalonic)… Expand
Determination of stability constants of complexes of MiKjHkL type in concentrated solutions of mixed salts.
- D. Janecki, K. Doktor, T. Michałowski
- Chemistry, Medicine
- Talanta
- 10 May 1999
This paper suggests a non-conventional approach towards the correct determination of stability constants K(ijk) of mixed complexes from the results of potentiometric titrations. The method is based… Expand
Gaussian filters with profile extrapolation
- D. Janecki
- Mathematics
- 1 October 2011
Abstract A filter with the transmission characteristic described by the Gaussian curve is the most common filter used in surface metrology to separate roughness, waviness, and form. The most natural… Expand
Sphericity measurements by the radial method: I. Mathematical fundamentals
- D. Janecki, K. Stȩpień, S. Adamczak
- Physics
- 2016
Traditionally, form errors of spherical components have been assessed on the basis of roundness profiles measured in several randomly selected cross-sections. However, such evaluation is superficial,… Expand
A generalized L2-spline filter
- D. Janecki
- Mathematics
- 1 July 2009
Abstract This paper presents a generalization of the L 2 -spline filter developed by Krystek [M. Krystek, Form filtering by splines, Measurement 18 (1996) 9–15]. Here, we assume that the distance… Expand
Investigating the influence of selected factors on results of V-block cylindricity measurements
- K. Stępień, D. Janecki, S. Adamczak
- Engineering
- 1 May 2011
Abstract The article deals with the method of cylindricity measurements using V-blocks. It was assumed, as was in the case of roundness profile measurements before, that the V-block method can be… Expand
