  • Skvortsov, Valentin A.; Sworowski, Piotr (Institute of Mathematics AS CR, 2006)
    Some observations concerning McShane type integrals are collected. In particular, a simple construction of continuous major/minor functions for a McShane integrand in R^n is given.
  • Sworowski, Piotr (Institute of Mathematics AS CR, 2007)
    Using the concept of the H1-integral, we consider a similarly defined Stieltjes integral. We prove a Riemann-Lebesgue type theorem for this integral and give examples of adjoint classes of functions.
  • Wilczyński, Maciej; Warmbier, Krzysztof (Instytut Technologii Drewna w Poznaniu / Wood Technology Institute, 2012)
    The paper presents the results of a study concerning the elastic moduli of veneers assembled in pine and beech plywood panels. The elastic modulus of veneers in the direction of the grain and the elastic modulus of veneers ...
  • Wilczyński, Arnold; Kociszewski, Marek (Springerlink, 2012)
    Elastic properties of the face and core layers of commercial three-layer particleboards were examined. The method of compressing the block specimens glued from strips of layers separated from boards, and measuring specimen ...
  • Kociszewski, Marek; Gozdecki, Cezary; Wilczyński, Arnold; Zajchowski, Stanisław; Mirowski, Jacek (Springerlink, 2012)
    Wood-polyvinyl chloride (PVC) composites were prepared using industrial wood particles used for manufacturing three-layer particleboards. The effect of particle size (0.25–0.5, 0.5–1, 1–2, and 2–4 mm) on the mechanical ...
  • Mikołajewska, Emilia; Mikołajewski, Dariusz (2012)
    Neuroplasticity (brain plasticity, cortical plasticity) is perceived an ability of nervous system to be changed (both in functional and structural areas) by processed signals (i. e. through activity, changes in environment, ...
  • Szczuka, Paulina (De Gruyter Open, 2012)
    In this paper, we present some results concerning functions which are represented as the maximum of two extra strong Świątkowski functions.
  • Warmbier, Krzysztof; Wilczyński, Arnold; Danecki, Leszek (Springerlink, 2013)
    The objective of this study was to investigate some mechanical and physical properties of one-layer particleboards made from various willow (Salix viminalis) and industrial pine wood particle mixtures bonded with urea ...
  • Grande, Zbigniew (Springer, 2013)
    Let f : R2 → R be a function with upper semicontinuous and quasi-continuous vertical sections fx(t) = f(x, t), t, x ∈ R. It is proved that if the horizontal sections fy(t) = f(t, y), y, t ∈ R, are of Baire class α (resp. ...
  • Mikołajewska, Emilia; Mikołajewski, Dariusz (2013)
    Neurological disorders may cause severe disorders. Scientists and clinicians still look forward to novel technologies allowing for precise, relevant diagnosis and effective treatment. One of the most promising technologies ...
  • Pawlak, Zenon; Petelska, Aneta D.; Urbaniak, Wiesław; Yusuf, Kehinde Q.; Oloyede, Adekunle (Springer-Verlag, 2013)
    The wettability of the articular surface of cartilage depends on the condition of its surface active phospholipid overlay, which is structured as multi-bilayer. Based on a hypothesis that the surface of cartilage facilitates ...
  • Szczuka, Paulina (De Gruyter Open, 2013)
    In this paper we introduce a connected topology T on the set ℕ of positive integers whose base consists of all arithmetic progressions connected in Golomb’s topology. It turns out that all arithmetic progressions which are ...
  • Szczuka, Paulina; Marciniak, Mariola (De Gruyter Open, 2013)
    In this paper we characterize the product of internally quasi- -continuous functions and we construct a bounded internally quasi-continuous strong Świa̧tkowski function which cannot be written as a finite product of ...
  • Dudziak, Marian; Domek, Grzegorz (2013)
    In the description of the process of coupling of pulleys with the toothed belt often existing solutions are used. Depending on the application they are similar to flat belt, chain or hellical gears. Euler made a first ...
  • Domek, Grzegorz (2013)
    The paper presents the results of measurements and analyzes gear timing belts, used in control systems. Many of the design features of timing belt determines its usefulness in such systems. Knowledge of technical parameters ...
  • Domek, Grzegorz (2013)
    Paper present main problems connected with exploitation of timing belts in fast growing production and processing systems. Mechatronics systems in glass production are the fastest developed field of application of ...
  • Grande, Zbigniew (Springer Science + Business Media New York, 2013-10)
    Let A be a nonempty family of functions from R to R. A function f : R → R is said to be strongly countably A-function if there is a sequence (fn) of functions from A such that Gr(f) ⊂ n Gr(fn) (Gr(f) denotes the graph of ...
  • Mikołajewska, Emilia; Mikołajewski, Dariusz; Komendziński, Tomasz; Dreszer-Drogorób, Joanna; Bałaj, Bibianna (2014)
    The huge complexity and variety of deficits in children, their continuous development, and co-operation simultaneously with children and their parents make clinical practice in pediatric neurorehabilitation particularly ...
  • Mikołajewski, Dariusz; Tomaszewska, Ewa; Kaczmarek, Mariusz (2014)
    Use of BCIs in patients with severe neurological deficits can improve their quality of life (QoL), provide them increased independence, and possibly increase effectiveness, shorten, and reduce cost of diagnosis, treatment, ...
  • Mikołajewska, Emilia; Macko, Marek; Ziarnecki, Łukasz; Stańczak, Sonia; Kawalec, Patryk; Mikołajewski, Dariusz (2014)
    3D printing, 3D scanning, and reverse engineering are relatively novel technologies, which may revolutionize scientific research within health sciences and clinical practice. Broader use of such technologies may cause ...
