A graph is said to be well-edge-dominated if all its minimal edge dominating sets are minimum. It known that every G also equimatchable, meaning maximal matching in maximum. In this paper, we show a connected, triangle-free, nonbipartite, graph, then one of three graphs. We characterize the split graphs and Cartesian products. particular, connected product $$G\Box H$$ well-edge-dominated, where...

Arithmetical structures on matrices were introduced in Corrales H, Valencia CE (Arithmetical graphs. Linear Algebra Appl, 536:120–151, 2018), which are finite whenever the matrix is irreducible. We generalize algorithm that computes arithmetical given CE, Villagrán RR (Algorithmic aspects of structures. Algeb 640:191–208, 2022), to an dominated polynomials. A polynomial integer multivariate pol...

Abstract The problem of common mode voltage in inverters can be considered as a major issue which leads to motor bearing failures. To eliminate these voltages, proposing some methods seems to be necessary. This paper has a comparative study on estimating modulation methods of eliminating common mode voltage. The main idea of these methods is based on generation of reference vector with nearest ...

The typical defect detection algorithm is ineffective due to the contrast between magnetic tile and various features. An improved YOLOv5-based algorithm, for detecting defects with varying features, suggested. procedure begins by incorporating CBAM into feature extraction network of YOLOv5. It improves learning capabilities target region filtering weighting vectors in such a way that processing...

mesophilic bacteria, fungi and actinomycetes varied during composting cycles with high numbers in the initial and final cycles with maximal values in compost c and d, and sharply decreased in the heating cycles. staphylococcus aureus and bacillus subtilis were dominated at the initial composting cycle. whereas, at maturity bacillus subtilis was the major followed by b.badies, b.polymixa and b.b...
