This paper discusses the results of the creep of material obtained with the use of the SLS additive technology. The author described the creep test, and a selected rheological model was adjusted to the creeping curve obtained in an experiment way. The parameter values of the rheological model were estimated. The anisotropy of the rheological properties of the material with regard to the print direction was determined.

“…The temperature difference between the inner and outer races reduces the bearing radial clearance. Therefore, the analysis of heat transfer in rolling bearing should be conduct (Błasiak, 2016). Appropriately value of bearing clearance affects the proper operation of the machine or device where rolling bearing is mounted (Smolík et al, 2017).…”

The paper presents research of the influence of the radial internal clearance of the rolling ball bearings on the basic exploitation parameter which is the level of vibration. The measuring method of radial internal clearance of rolling bearings and measuring device are described. The 6304 type ball rolling bearings were used in research. The experimental research consisted of measurements of radial internal clearance and vibration level. The vibration analysis was divided into three basic frequency bands: low (50-300 Hz), medium (300-1800 Hz) and high (1800-10 000 Hz). The research was carried out in Laboratory of Rolling-Elements Bearings located in Kielce University of Technology. The research results showed that the increase of the radial clearance values affect the level of vibration generated by rolling bearings. The biggest influence was noted in the medium vibration frequency band.

“…To finish, the diffusion of heat in a semi-infinite environment subjected to a heat flux q(t) on its surface boundary S. In [4,5], authors demonstrate that the mathematical equations describing the unidirectional heat transfer in the environment reveal a real order of derivation of the temperature at the point of abscissa x = 0.…”

This article deals with fractional systems that represent better physical process and guarantee a very small number of parameters that can reduces the computation time. It focuses in particular on the state-space representation which highlights the state variables and allows to study the internal behavior of the system taking into account the initial state. Moreover, this representation adapts better to the multiple input multiple-output case. It also discusses the discretization of fractional system to finally adapt the Model Predictive Control to apply it and shows its efficiency and performance in these systems. The main objective of this article is to compare the commensurate and noncommensurate fractional models performance, calculation time and ease of use.
