A solution of the vibration attention problem on a flexible structure from a dynamic vibration absorption perspective is experimentally and numerically studied in this article.Linear and nonlinear dynamic vibration absorbers are properly implemented on a primary structure of n degrees of freedom through a modal decomposition analysis and leather ba
In wireless sensor networks, the reliability of communication can be greatly improved by applying low-density parity-check (LDPC) codes.Algorithms based on progressive-edge-growth (PEG) pattern and quasi-cyclic (QC) pattern are the mainstream approaches to constructing LDPC codes with good performance.However, these algorithms are not guaranteed to
Mapping of above-ground phytomass provides a baseline for monitoring climate-induced changes, especially in the northern regions.This is important for practical applications, such as assessing quality of pastures and defining reindeer migration routes.Use of very high resolution (1 m and better) aerial and satellite images is of particular interest
The objective of this work was to characterize and quantify the genetic hippie love spray variability of 39 barley elite genotypes from a Brazilian working collection belonging to Embrapa, using RAPD (Random Amplified Polymorphic DNA) molecular markers.Genomic DNA samples were extracted from leaves of each genotype and 15 decamer primers were used
The economic voting literature disagrees over the exogeneity of economic perceptions on individual electoral behavior.One side argues that economic perceptions are driven by partisan dispositions, which then calls into question the substantive importance of this factor brynje tactical beanie in assessing electoral behavior.A second side argues that
