• On the Usefulness of the Generalised Additive Model for Mean Path Loss Estimation in Body Area Networks

  Publikacja

  • M. Laskowski
  • S. J. Ambroziak
  • L. M. Correia
  • K. Świder

  - IEEE Access - Rok 2020

  In this article, the usefulness of the Generalised Additive Model for mean path loss estimation in Body Area Networks is investigated. The research concerns a narrow-band indoor off-body network operating at 2.45 GHz, being based on measurements performed with four different users. The mean path loss is modelled as a sum of four components that depend on path length, antenna orientation angle, absolute difference between transmitting...

• GENERALISED HERSCHEL MODEL APPLIED TO BLOOD FLOW MODELLING

  Publikacja

  • K. Tesch

  - TASK Quarterly - Rok 2012

  This paper introduces a new rheological model of blood as a certain generalisation of the standard Herschel-Bulkley model. This model is a rheological constitutive equation and belongs to the group of the so-called generalised Newtonian fluids. Experimental data is compared with results, obtained from the new model, to demonstrate that it allows for the best agreement together with Luo-Kuang model. The new model may be easily implemented...

• Mathematical analysis of a generalised p53-Mdm2 protein gene expression model

  Publikacja

  • M. Bodnar

  - APPLIED MATHEMATICS AND COMPUTATION - Rok 2018

  We propose the generalisation of the p53-Mdm2 protein gene expression model introduced by Monk (2003). We investigate the stability of a unique positive steady state and formulate conditions which guarantee the occurrence of the Hopf bifurcation. We show that oscillatory behaviour can be caused not only by time lag in protein transcription process, but also can be present in the model without time delay. Moreover, we investigate...

• Performance Evaluation of GAM in Off-Body Path Loss Modelling for Body Area Networks

  Publikacja

  • M. Laskowski
  • S. J. Ambroziak
  • L. M. Correia
  • K. Świder

  - Rok 2021

  This paper addresses the performance evaluation of an off-body path loss model, based on measurements at 2.45 GHz, which has been developed with the use of the Generalised Additive Model, allowing to model a non-linear dependence on different predictor variables. The model formulates path loss as a function of distance, antennas’ heights, antenna orientation angle and polarisation, results showing that performance is very sensitive...

• Tensile and Fatigue Behavior of Additive Manufactured Polylactide

  Publikacja

  • Ł. Pejkowski
  • T. Topoliński

  - 3D Printing and Additive Manufacturing - Rok 2019

  This article presents the results of monotonic tensile and fatigue tests conducted on commercial polylactide or polylactic acid (PLA). The results of fatigue tests for this material present in the literature are limited, especially for additive manufactured elements. The specimens were manufactured using the injection molding and the fused filament fabrication (FFF) method. The FFF specimens were divided into five subgroups, depending...

  - EPL-EUROPHYS LETT - Rok 2015

  Distributions of accelerations and decelerations, obtained from increments of heart rate recorded during a head-up tilt table (HUTT) test provide short-term characterization of the complex cardiovascular response to a rapid controlled dysregulation of homeostasis. A generalised statistic is proposed for evaluating the neural reflexes responsible for restoring the homeostatic dynamics. An evaluation of the effects on heart rate...

• Reduced model of gyroscopic system

  Publikacja

  • C. Orlikowski
  • R. Hein

  - Rok 2008

  The paper presents the method of model reduction for the system with gyroscopic interactions. Two methods were used to obtain the approximate discrete models of the continuous structure: the modal decomposition method and the rigid finite element method. The first approach is used for this part of a system for which it is easy to formulate orthogonality conditions, meanwhile the second one is used for other part. The method enables...
