Two polychaete species, Hypania invalida and Laonome calida, were found in the Upper Odra River in 2016.Both species were recorded close to a natural river bank down to 1 m depths.They inhabited sandy-gravelly and sandy-muddy sediments.H.invalida is an alien invasive Soldering Stations Ponto-Caspian species, previously known in Poland from the Odra
Three-Dimensional Reconstruction of Partially Coherent Scatterers Using Iterative Sub-Network Generation Method
Synthetic aperture radar tomography (TomoSAR) has gained significant attention for three-dimensional (3D) imaging in urban environments.A notable limitation of traditional TomoSAR approaches is their primary focus on persistent scatterers (PSs), disregarding targets with temporal decorrelated characteristics.Temporal Figures variations in coherence
New digital demodulator with matched filters and curve segmentation techniques for BFSK demodulation: Analytical description
The present article relates in general to digital demodulation of Binary Frequency Shift Keying (BFSK).The objective of the present research is to obtain a new processing method for demodulating BFSK-signals in order to reduce hardware complexity in comparison with other methods reported.The solution Figures proposed here makes use of the matched f
