3D printing technologies in rehabilitation engineering

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 ...
Adjoint classes of functions in the H1 sense

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.
BCI-controlled mechatronic devices, systems, and environments

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, ...
The closures of arithmetic progressions in the common division topology on the set of positive integers

Szczuka, Paulina (De Gruyter Open, 2014)

In this paper we characterize the closures of arithmetic progressions in the topology T on the set of positive integers with the base consisting of arithmetic progressions {an + b} such that if the prime number p is a ...
Computational approach to neural plasticity of nervous system on system level

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, ...
Connections between connected topological spaces on the set of positive integers

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 ...
Construction of the solution of the thermal-convective drying problem for porous solids in drying plants

Chaplya, Yevhen; Hayvas, B. I.; Torskyy, A. R. (2015)

In this paper the approximate solutions of the one-dimensional linear mathematical model of porous bodies drying are obtained, which makes it possible to establish the temperature of the phase transition for arbitrary ...
Contact Problems Between the Hub and the Shaft with a Three-angular Shape of Cross-section for Different Angular Positions

Dudziak, Marian; Domek, Grzegorz; Kołodziej, Andrzej; Talaśka, Krzysztof (Elsevier, 2014)

The actual state of the macrogeometry of the surfaces of mating elements, particularly form deviations, has a direct influence on constructional features and the functionality of the connections which are applied in ...
Description of Timing Belt Coupling Using a Pendulum with Variable Coupling Point

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 ...
Design of the Tendon Structure in Timing Belts

Domek, Grzegorz; Kołodziej, Andrzej (Elsevier, 2016)

The paper presents the design issues of support layer of timing belts. The construction of the power transmission belts needs different manufacturing process. This requires a proper design of the carrier layer, single or ...
Effect of industrial wood particle size on mechanical properties of wood-polyvinyl chloride composites

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 ...
Elastic moduli of veneers in pine and beech plywood

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 ...
Elastic properties of the layers of three-layer particleboards

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 ...
Interactive motion-controlled games in the neurorehabilitation of adult post-stroke patients

Mikołajewska, Emilia; Mikołajewski, Dariusz (2015)

Despite efforts of scientists and clinicians stroke still constitutes one of the major causes of disability worldwide. Motion-controlled video games become increasingly common adjunct to the traditional physical therapy. ...
Lamellar slippage of bilayers - A hypothesis on low friction of natural joints

Pawlak, Zenon; Urbaniak, Wiesław; Hagner-Derengowska, Magdalena; Hagner, Wojciech (AVS: Science & Technology of Materials, Interfaces, and Processing, 2014-12-11)

The cartilage’s amphoteric surface behavior is a physical phenomenon in biological lubrication. However, there is a lack of knowledge on amphoteric phospholipids bilayers and in overcoming friction in cartilage joints. In ...
Magnetoencephalograpy in brain-computer interfaces- current and future solutions

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 ...
Mathematical Modeling of Random Diffusion Flows in Two-Phase Multilayered Stochastically Nonhomogeneous Bodies

Chaplya, Yevhen; Chernukha, Olha; Davydok, Anastasiia (2015)

An approach for studying stochastical diffusion flows of admixture particles in bodies of multiphase randomly nonhomogeneous structures is proposed, according to which initial-boundary value problems of diffusion are ...
The maximal class with respect to maximums for the family of upper semicontinuous strong Świątkowski functions

Szczuka, Paulina (De Gruyter Open, 2014)

The main goal of this paper is to characterize the maximal class with respect to maximums for the family of upper semicontinuous strong Świątkowski functions.
Maximal Classes For Lower And Upper Semicontinuous Strong Świątkowski Functions

Szczuka, Paulina (De Gruyter Open, 2014)

In this paper, we characterize the maximal additive and multiplicative classes for lower and upper semicontinuous strong Świątkowsk functions and lower and upper semicontinuous extra strong Świątkowski functions. Moreover, ...
