• Structural and Temporal Topic Models of Feedbacks on Service Quality – A Path to Theory Development?

  Publikacja

  • A. Ojo
  • N. Rizun

  - Rok 2020

  There is growing interest in applying computational methods in analysing large amount of data without sacrificing rigour in Information Systems research. In this paper, we demonstrate how the use of structural and temporal topic modelling can be employed to produce insights of both theoretical and practical importance from the analysis of textual comments on the quality of services in hospitals. As a first step, we revealed the...

• The Algorithm of Modelling and Analysis of Latent Semantic Relations: Linear Algebra vs. Probabilistic Topic Models

  Publikacja

  • N. Rizun
  • W. Waloszek
  • Y. Taranenko

  - Rok 2017

  This paper presents the algorithm of modelling and analysis of Latent Semantic Relations inside the argumentative type of documents collection. The novelty of the algorithm consists in using a systematic approach: in the combination of the probabilistic Latent Dirichlet Allocation (LDA) and Linear Algebra based Latent Semantic Analysis (LSA) methods; in considering each document as a complex of topics, defined on the basis of separate...

• Non-linear viscoelastic modelling of earthquake-induced structural pounding

  Publikacja

  • R. Jankowski

  - Rok 2005

  Celem artykułu jest analiza nieliniowego lepko-sprężystego modelu siły zderzenia, który ma zastosowanie do symulacji zderzeń pomiędzy konstrukcjami budowlanymi podczas trzęsień ziemi. Efektywność modelu sprawdzono poprzez porównanie wyników symulacji numerycznych z wynikami eksperymentalnymi. Wyniki pracy pokazują, iż w stosunku do innych modeli zderzeń, nieliniowy model lepko-sprężysty umożliwia najdokładniejszą symulację siły...

• Discrete Modelling of Micro-structural Phenomena in Granular Shear Zones

  Publikacja

  • M. Nitka
  • J. Tejchman
  • J. Kozicki

  - Rok 2015

  The micro-structure evolution in shear zones in cohesionless sand for quasi-static problems was analyzed with a discrete element method (DEM). The passive sand failure for a very rought retaining wall undergoing horizontal translation towards the sand backfill was discussed. To simulate the behaviour of sand, the spherical discrete element model was used with elements in the form of rigid spheres with contacts moments.

• Linear viscoelastic modelling of damage-involved structural pounding during earthquakes

  Publikacja

  • S. Mahmoud
  • R. Jankowski

  - Key Engineering Materials - Rok 2010

  Damage-involved structural pounding during earthquakes has been recently intensively studied using different impact force models. The results of the previous studies indicate that the linear viscoelastic model is relatively simple yet accurate in modelling pounding-involved behaviour of structures during earthquakes. The only shortcoming of the model is a negative value of the pounding force occurring just before separation, which...

  Publikacja

  • A. R. Bakhtari
  • V. Kumar
  • M. Waris
  • C. Sanin
  • E. Szczerbicki

  - Procedia Computer Science - Rok 2020

  For the last few years, the fourth industrial revolution, known as Industry 4.0, has been a hot topic among academics. Industry 4.0 literature involves researches presenting studies related to its different aspects including challenges, opportunities, implementation and adoption. However, a detailed study of challenges and barriers towards the Industry 4.0 implementation in manufacturing industries is missing. Hence, this paper...

  - Construction and Building Materials - Rok 2022

  One of the most essential components of structural design for civil engineers is to build a system that is resistant to environmental conditions such as harsh chemical environments, and catastrophic disasters like earthquakes and hurricanes. Under these circumstances and disturbances, conventional building materials such as steel and concrete may demonstrate inadequate performance in the form of corrosion, deterioration, oxidizing,...
