  - Applied Mechanics and Materials - Rok 2016

  In this paper new kinematics systems were studied for a single lapping process. In order to ensure the constant profile wear of the tool a standard kinematic system can be changed. Lapping is carried out by applying loose abrasive grains between two surfaces and causes a relative motion between them. The result is a finish of multi-directional lay. During process, the mechanism of surface formation are decisively affected by a...

• Optimization of Single-Sided Lapping Kinematics Based on Statistical Analysis of Abrasive Particles Trajectories

  Publikacja

  • A. Barylski

  - Rok 2017

  The chapter presents the influence of selected kinematic parameters on the geometrical results of the single-sided lapping process. The optimization of these parameters is aimed at improving the quality and flatness of the machined surfaces. The uniformity of tool wear was assumed as main optimization criterion. Lapping plate wear model was created and in detail was analyzed. A Matlab program was designed to simulate the abrasive...

• Automatic Analysis of Trajectories of Moving Objects

  Publikacja

  • J. Dąbrowski

  - HYDROACOUSTICS - Rok 2013

  Ongoing monitoring is essential to providing security and safety of maritime and air operations. This paper presents the research in the area of automatic analysis of movement of unrestricted vehicles like ships and air-planes. The analysis is aimed at extraction of trajectory information, and the results can be used to identify anomalous behaviour in archived and real-time data. In this paper we focus on data acquired using the...

• Assessment of Trajectories of Non-bankrupt and Bankrupt Enterprises

  Publikacja

  • T. Korol

  - European Research Studies Journal - Rok 2020

  The aim of this study is to show how long-term trajectories of enterprises can be used to increase the forecasting horizon of bankruptcy prediction models. The author used seven popular forecasting models (two from Europe, two from Asia, two from North America and one from Latin America). These models (five multivariate discriminant analysis models and two logit models) were used to develop 17-year trajectories separately for non-bankrupt...

• Distributed tracking system with central trajectories initialization

  Publikacja

  - Rok 2008

  W pracy rozważa się problem wyznaczania trajektorii przy użyciu rozproszonego, wieloczujnikowego systemu. W systemie tego typu trajektoria poruszającego się obiektu wyznaczana jest przez grupę lokalnych estymatorów stanu. Każdy z estymatorów korzysta z filtru Kalmana i danych z pojedynczego źródła w celu określenia trajektorii obiektu. Zwykle źródła danych (czujniki) pracujące na potrzeby estymatorów lokalnych nie obserwują takiego...

• The trajectories of the financial crisis of companies at risk of bankruptcy

  Publikacja

  • T. Korol

  - International Journal of Management and Applied Science (IJMAS) - Rok 2017

  This article concerns the assessment of the trajectory of the collapse of enterprises in Central Europe. The author has developed a model of a Kohonen artificial neural network. This model was used to determine 6 different classes of risk and was allowed to graphically determine the 5- to 10-year trajectory of going bankrupt. The study used data on 140 companies listed on the Warsaw Stock Exchange. This population was divided into...
