Let [Formula: see text] be the monoid generated by [Formula: see text] We introduce the homogeneous catenary degree of [Formula: see text] as the smallest N ∈ ℕ with the following property: for each [Formula: see text] and any two factorizations u, v of a, there exist factorizations u = w1,…,wt = v of a such that, for every k, d (wk,wk+1) ≤ N, where d is the usual distance between factorizations, and the length of wk, |wk|, is less than or equal to max{|u|, |v|}.

Abstract:

In 1876 Brocard, and independently in 1913 Ramanujan, asked to find all integer solutions for the equation \(n!=x^2-1\). It is conjectured that this equation has only three solutions, but up to now this is an open problem. Overholt observed that a weak form of Szpiro's-conjecture implies that Brocard's equation has finitely many integer solutions. More generally, assuming the ABC-conjecture, Luca showed that equations of the form \(n!=P(x)\) where \(P(x)\in\mathbb{Z}[x]\) of degree \(d\geq 2\) have only finitely many integer solutions with \(n\gt 0\). And if \(P(x)\) is irreducible, Berend and

Abstract:

This article addresses some apparent problems in the practical application of factorial models of return on equity. Our investigations demonstrate that the main problem lies in the interpretation of the influence of financial leverage (degreel of indebtedness). From the application of factorial models it follows that the higher the financial lever, the higher the return on equity. But in economic practice, increasing the degree of indebtedness cannot permanently contribute to increasing the profitability of equity because the permissible limit of the indebtedness degree may constitute no more

Let X ⊂ ℙ2m+1 be a projective variety with isolated singularities, complete intersection of a smooth hypersurface of degree k, with a smooth hypersurface F of degree n > k. Denote by NSm(F) and NSm(X) the mth Néron–Severi groups. We prove that if rkNSm(F) = 1, then rkNSm(X) = 1. Moreover, we prove that if [Formula: see text] is general and n > max {k, 2m + 1}, then the natural map NSm(X) ⊗ ℚ → NSm(F) ⊗ ℚ is surjective. When X is a threefold, we deduce that X is factorial if and only if rkNS2(F) = 1. This allows us to prove the existence of factorial threefolds with many singularities.

Wüstite sinter samples with different basicity (0.5, 1.0, and 2.0) are reduced with a gas mixture consisting of 30% CO, 10% H2, 5% CO2, and 55% N2 at 950–1100°C. In all cases, the reduction degree of wüstite increased with basicity and temperature. A 23 factorial design is applied to derive a regression model based on the experimental data of acidic (CaO/SiO2 = 0.5) and basic (CaO/SiO2 = 2.0) wüstite which is reduced at 950°C and 1100°C for 5 and 35 min.

There is a body of research showing that those cutoff values cannot be generalized. Model fit does not only depend on the severity of misspecification, but also on nuisance parameters, which are independent of the misspecification. Using a simulation study, we demonstrate their influence on measures of model fit. We specified a severe misspecification, omitting a second factor, which signifies factoria

Issues such as the low presence of concepts related to gender in teaching guides or the lack of interest of teachers regarding their inclusion in classes lead to defining research to know and understand the conceptions of a sample of 162 teachers in the initial teacher train

Abstract:

Roughly speaking, knowledge networks are explained from a neural network in which degrees of learning are established, considering the differences between the input layer, the intermediate or hidden layer and the output layer. A non-experimental, cross-sectional and exploratory study was carried out with a non-probabilistic selection of 300 students, managers and teachers from a public university in central Mexico. The results show a factorial asymmetry of one input layer unit for three output layer units, suggesting that there is a significant degree of learning around the knowledge network.

Abstract:

Abstract Setting the building construction duration for vertical residential works is made still in the study phase of economic and financial feasibility of the project and, in most cases, in an empirical way, increasing the uncertainties and the risks to fulfill the set deadline. However, there are computational intelligence tools that can contribute to reduce the degree of uncertainty. This study aimed to investigate the use of a hybrid system to estimate the deadline for vertical residential building works from design and production characteristics using factorial analysis and Fuzzy Systems

Abstract:

A great number of real-world problems can be associated with multi-criteria decision-making. These problems are often characterized by a high degree of uncertainty. Intuitionistic fuzzy sets (IFSs) are a generalized form of an ordinal fuzzy set to deal with this natural uncertainty. In this paper, we propose a hybrid version of the intuitionistic fuzzy ELECTRE based on VIKOR method, which was never considered before. The advantage and strengths of the intuitionistic fuzzy ELECTRE based on VIKOR method as decision aid technique and IFS as an uncertain framework make the proposed method a suitab

Abstract:

The article analyzes the section "National Defense", which has an impact on the number of expenditures for its subsections. This degree of influence of the size of each subsection on the total amount of the section allows you to determine the factorial stochastic analysis. Thus, the larger the share of a subsection in a section, the stronger its impact on the final amount of spending on national defense.
