• Application of the Msplitmethod for filtering airborne laser scanning data-sets to estimate digital terrain models

  Publikacja

  • W. Błaszczak-Bąk
  • A. Janowski
  • W. Kamiński
  • J. Rapiński

  - INTERNATIONAL JOURNAL OF REMOTE SENSING - Rok 2015

  ALS point cloud filtering involves the separation of observations representing the physical terrain surface from those representing terrain details. A digital terrain model (DTM) is created from a subset of points representing the ground surface. The accuracy of the generated DTM is influenced by several factors, including the survey method used, the accuracy of the source data, the applied DTM generation algorithm, and the survey...

• Fast multi-objective optimization of antenna structures by means of data-driven surrogates and dimensionality reduction

  Publikacja

  • S. Kozieł
  • A. Pietrenko-Dąbrowska

  - IEEE Access - Rok 2020

  Design of contemporary antenna structures needs to account for several and often conflicting objectives. These are pertinent to both electrical and field properties of the antenna but also its geometry (e.g., footprint minimization). For practical reasons, especially to facilitate efficient optimization, single-objective formulations are most often employed, through either a priori preference articulation, objective aggregation,...

• ECHOES REDUCTION DURING DIGITAL DATA TRANSMISSION IN HYDROACOUSTIC CHANNEL – LABORATORY EXPERIMENT

  Publikacja

  • A. Czapiewska
  • R. Studański
  • A. Żak
  • B. Żak

  - Rok 2019

  The possibility of using a hydroacoustic channel for digital data transmission is very limited. This is due to the effect of multipath propagation of the emitted acoustic wave and the damping of the mechanical wave in this medium, which increase with frequency. The first of these phenomena results in inter-symbol interference disturbances in data transmission systems, including even hundreds of symbols. Due to the number of reflections...

• Improved Uniform Sampling in Constrained Domains for Data-Driven Modelling of Antennas

  Publikacja

  • S. Kozieł
  • A. Sigursson

  - Rok 2018

  Data-driven surrogate modelling of antenna structures is an attractive way of accelerating the design process, in particular, parametric optimization. In practice, construction of surrogates is hindered by curse of dimensionality as well as wide ranges of geometry parameters that need to be covered in order to make the model useful. These difficulties can be alleviated by constrained performance-driven modelling with the surrogate...

  • M. Danowska
  • M. Strankowski
  • K. Formela

  - JOURNAL OF REINFORCED PLASTICS AND COMPOSITES - Rok 2015

  During the synthesis of rigid polyurethane foams, petrochemical polyol was substituted with polyglycerol, the product of thermo-catalytic polycondensation of waste glycerol, resulting from biodiesel production. Two types of ground tire rubbers, untreated and thermo-mechanically reclaimed, were used to obtain ‘‘green’’ polyurethane-polyglycerol composite foams. Samples were prepared by a single-step method for the ratio of NCO/OH...

• Low-Cost Data-Driven Surrogate Modeling of Antenna Structures by Constrained Sampling

  Publikacja

  • S. Kozieł

  - IEEE Antennas and Wireless Propagation Letters - Rok 2016

  Full-wave electromagnetic (EM) analysis has become one of the major design tools for contemporary antenna structures. Although reliable, it is computationally expensive which makes automated simulation-driven antenna design (e.g., parametric optimization) difficult. This difficulty can be alleviated by utilization of fast and accurate replacement models (surrogates). Unfortunately, conventional data-driven modeling of antennas...
