In this paper, a new rateless scheme based on the extendibility of systematic polar codes Horse Rugs is proposed, which is applicable for the scenario without channel state information (CSI).With detailed analyses on the existing rateless schemes, we obtain the drawbacks and difficulties which can make the schemes dysfunctional.We expound the exten
For some stream structures such as barrages, regulators, as well as change of channel cross section, the downstream expansion transitions structures are the common requirement.Eddies, as a result of the flow separation in such structures leads to destruction the bed and sides of the downstream channel.Head loss, on the other hand, produced through
The developed method of steganographic hiding of text information in an audio signal based on the wavelet transform acquires a deep meaning in the conditions of the use by an attacker of deliberate unauthorized manipulations with a steganocoded audio signal to distort the text information embedded in it.Thus, increasing the robustness of the stego-
This study looks at population response to government containment strategies during initial stages of the COVID-19 pandemic in four high-trust Northern European countries-Denmark, Germany, the Netherlands, and Sweden-with special emphasis on expressions of governmental trust.Sentiment analysis and topic modeling analysis were performed using Twitte
