  Publikacja

  • M. Lech
  • B. Kostek

  - Rok 2010

  W rozdziale przedstawiono interfejs sterowania komputerem za pomocą gestów rąk, należący do grupy systemów czasu rzeczywistego o łagodnych granicach (ang. soft real-time). Komponentami systemu są: komputer klasy PC, kamera internetowa, rzutnik multimedialny i ekran dla rzutnika. Oprogramowanie interfejsu opracowano w oparciu o środowiska J2SE i Visual Studio C++ z użyciem biblioteki OpenCV. Moduł systemu realizujący interpretację...

• Parallel Background Subtraction in Video Streams Using OpenCL on GPU Platforms

  Publikacja

  • G. Szwoch

  - Rok 2014

  Implementation of the background subtraction algorithm using OpenCL platform is presented. The algorithm processes live stream of video frames from the surveillance camera in on-line mode. Processing is performed using a host machine and a parallel computing device. The work focuses on optimizing an OpenCL algorithm implementation for GPU devices by taking into account specific features of the GPU architecture, such as memory access,...

• OpenGL accelerated method of the material matrix generation for FDTD simulations

  Publikacja

  • S. Orłowski
  • T. Stefański

  - Rok 2014

  This paper presents the accelerated technique of the material matrix generation from CAD models utilized by the finite-difference time-domain (FDTD) simulators. To achieve high performance of these computations, the parallel-processing power of a graphics processing unit was employed with the use of the OpenGL library. The method was integrated with the developed FDTD solver, providing approximately five-fold speedup of the material...

• Investigation of stability and limit load of a truss overhead opened bridge

  Publikacja

  • Ł. Żmuda-Trzebiatowski
  • P. Iwicki
  • M. Krajewski

  - Rok 2016

  The paper presents selected methods of determining stability and limit load of a truss top chord in opened bridges. These methods include linear buckling and non-linear static analysis based on the finite element method and algorithms based on design code procedures. The described methods were tested on an example of a steel footbridge situated in Straszyn. The results of stability analysis are compared. The results of geometrical...

• Assessment of OpenMP Master–Slave Implementations for Selected Irregular Parallel Applications

  Publikacja

  • P. Czarnul

  - Electronics - Rok 2021

  The paper investigates various implementations of a master–slave paradigm using the popular OpenMP API and relative performance of the former using modern multi-core workstation CPUs. It is assumed that a master partitions available input into a batch of predefined number of data chunks which are then processed in parallel by a set of slaves and the procedure is repeated until all input data has been processed. The paper experimentally...

• Evaluation of the Impact of Storage Conditions on the Biogenic Amines Profile in Opened Wine Bottles

  Publikacja

  • J. Płotka-Wasylka
  • V. Simeonov
  • J. Namieśnik

  - MOLECULES - Rok 2018

  A survey of biogenic amine (BA) profiles in opened wine bottles has been established to monitor the level of biogenic amines (BAs) in opened bottles against time and other conditions. Bottles of red and white wine were submitted to different temperatures, stopper type (screw cap, cork), and use of vacuum devices. A total of six wines made from a variety of grapes were obtained from vineyards from regions across Poland. Dispersive...

• Restricted open shop scheduling

  Publikacja

  • M. Małafiejski
  • K. Pastuszak

  - Journal of Theoretical and Applied Computer Science - Rok 2017

  In the real applications the open shop scheduling models often require some additional constraints and adequate models. We concern the restrictions in the open shop scheduling related to an instance of the problem and to a feasible solution. Precisely, we require that each jobs consists of the bounded number of operations and each machine has a bounded load (i.e., the total number of operations executed on this machine in a schedule)....
