Let us consider questions, which are connected to the research of terms of hardware and software implementation digital signal processing (DSP) methods. Theoretical basis of this research are methods of non-recursive difference of digital filtration with integer difference coefficients different orders of difference and methods of multistage discrete Fourier transform (DFT) based on such digital filtration. The purpose of the study is the research and formalization of necessary and sufficient condition of lowering hardware costs in hardware and software implementation of methods multistage DFT of digital signals on programmable logic devices (PLD). For reaching the research goal there are used methods of direct search and comparative analysis of results of such realization of methods of multi-stage DFT of digital multi-band signals, while filtering these signals, which are based on their non-recursive difference digital filtering with integer difference values coefficients and different orders of magnitude of difference. There are described abilities and specialties of PLD, which are built using architecture of a coarse-grained or fine-grained architecture or using combined architecture, which connects the convenience of implementing digital processing algorithms signals on the basis of tables of code conversion and reconfigurable memory modules. It is clear that a necessary and sufficient condition of lowering hardware costs in terms of hardware and software realization of methods for multi-stage DFT of digital signals on PLD is the triviality of meanings of integer difference coefficients of a non-recursive difference digital high difference orders’ filtration, which ensure this information. There is mentioned a formula, which allows making such condition. The practical significance of the research results consists of defining the necessary and sufficient condition of lowering hardware costs in terms of hardware and software implementation on PLD methods of multi-stage DFT signals based on their non-recursive digital difference filtering with integer values differential coefficients of various orders of magnitude difference. The novelty of research results lies in formalization of this condition. The reliability of the research results confirms their compliance with the results of well-known developments of DSP methods.
The 2020 economic crisis brought on by the coronavirus pandemic has affected many sectors of the economy. The markets for air travel and commercial aircraft have been particularly impacted. The present work assesses the current state of aviation and its economic prospects. Global analysis reveals the key economic, political, and social factors determining the outcome of the crisis. Possible remedies are considered, with a particular focus on consolidating Russia’s economic position, especially in terms of aviation. The condition of participants in the supply chain is reviewed, and possible pathways for their development are sketched. Recommendations are made regarding the development of Russia’s economy, the appropriate use of economic prediction and management, and the best practices in crisis management.
In this article, the issues of improving management mechanisms, assessing and identifying the risks of an economic entity's activities by monitoring and analyzing the levels of human capital and the potential of its employees are considered. There is a hypothesis about the existing fundamental tendency of changing the status of employee of organization from the performer of standard operations to the creator of the product and associated risks. A mechanism is proposed for applying a system of key performance indicators (KPI) to assess the levels of human capital and potential in order to manage the production stability and competitiveness of organization, as well as to identify and assess the risks of its activities in time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
