  A signal transmitted in an Underwater Acoustic Communication (UAC) system operating in a shallow-water channel suffers from strong time dispersion due to multipath propagation. This causes the Inter-Symbol Interference (ISI) observed in the received signal, which significantly limits the communication system’s reliability and transmission rate. In such propagation conditions, the Direct-Sequence Spread Spectrum (DSSS) method is...

• Modeling DAC Application Execution Time

  Publikacja

  • J. Kuchta

  - Rok 2016

  An application written in the Divide And Conquer paradigm is more difficult to model than SPMD application because of complex algorithm, causing use of many coefficients in a computational complexity function. Processors are divided into various layers, each layer contains different number of processors. Data packets processed in different layers and transferred between layers have different length. Moreover first layer processors use...

  - Rok 2004

  Przeanalizowano efektywność działania warstwy MAC-c/sh w warstwie drugiej stosu protokołów radiowych systemu UMTS. Omówiono wpływ parametrów stosu oraz rodzaju używanych algorytmów na działanie MAC-c/sh.Zaproponowano efektywny algorytm zarządzania kolejkami priorytetowymi, oparty na dyscyplinie kolejkowej WRR, przy multipleksowaniu ruchu na kanale transportowym FACH. Przedstawiono również nowy algorytm sterowania natężeniem ruchu...

• UAV IN TODAYS PHOTOGRAMMETRY – APPLICATION AREAS AND CHALLENGES

  Publikacja

  • P. Burdziakowski

  - Rok 2018

  There a few important factors, that nowadays, unmanned aerial vehicles (UAV) are used by wider community, and for cases and applications, that cannot be performed never before. Small UAVs, as a photogrammetry measurement tool provide flexibility, reliability, are safe and easy to use, can be deployed in minutes, initial measurement can be delivered yet on the field, and final accurate measurements are calculated in a very short...

• Reliability Modeling for SPMD and DAC Applications in MERPSYS

  Publikacja

  • J. Kuchta

  - Rok 2016

  In this chapter we shall see a method for modeling of reliability of application execution in the MERPSYS system, and the results of reliability simulation of the same SPMD and DAC application which we have previously presented in this book. Unlike energy usage modeling and modeling of execution efficiency we could not compare the reliability model and simulation results to real experiment just because the experiment would last too...

• Energy Consumption Modeling in SPMD and DAC Applications

  Publikacja

  • J. Kuchta

  - Rok 2016

  In this chapter, we show a study of energy consumption during execution of SPMD and DAC application – the same applications which time of execution we modeled in the previous two chapters. We measured an average power usage at a single node of the GALERA+ cluster during application execution and then we modeled the total energy consumption by the application. Next we simulated the applications using MERPSYS and we compared the...
