  Publication

  • S. J. Ambroziak

  - International Journal of Antennas and Propagation - Year 2019

  The concept of an experimental test bed for system loss and channel impulse response measurements for off-body and body-to-body radio channels in wireless body area networks (WBANs) is fully described. The possible measurement scenarios that may occur in investigation of off-body and body-to-body channels are classified and described in detail. Additionally, an evaluation is provided of the standard and expanded uncertainties of...

  - Academic Journal of Modern Philology - Year 2021

  The present paper examines the topic of aliases of criminals, which seems to be understudied in linguistic research. Therefore, this article’s primary goal is to describe how criminals’ aliases are created and what are the differences and similarities in that process in English, French, and Polish. Firstly, the theoretical background concerning the topic of pseudonyms is presented. Then, the corpus gathered for this paper (available...

  - Przegląd Telekomunikacyjny + Wiadomości Telekomunikacyjne - Year 2016

  Niniejszy referat dotyczy oceny efektywności odbioru zbiorczego polaryzacyjnego warunkach propagacji sygnałów wewnątrz budynków. W artykule scharakteryzowano warianty odbioru zbiorczego oraz stosowane w nich metody łączenia sygnałów. Ponadto, zdefiniowano wyrażenia służące szacowaniu zysku odbioru zbiorczego dla tych metod. Przedstawiono również metodykę przeprowadzonych badań pomiarowych oraz dokonano analizy wyników tych badań.

  Easy-to-perform, fast, and inexpensive methods of differentiation of Escherichia coli strains beyond the species level are highly required. Herein two new, original tools for genotyping of E. coli isolates are proposed. The first of the developed method, a PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) test uses a highly variable fliC gene, encoding the H antigen as a molecular target. The designing...

  - Year 2019

  The characterization of slow and fast fading in Wireless Body Area Networks with space diversity scheme has been presented. The analysis, based on the measurements at 2.45 GHz in indoor environment, has shown that for all investigated configurations of receiving wearable antennas the correlation coefficient values of received signals’ parameters are below the assumed value of 0.5, being close to zero for the vast majority of cases. It...
