On the Solutions of a Fourth Order Difference Equation

Universal Journal of Mathematics and Applications, 2021
In this paper, we solve and study the global behavior of the well defined solutions of the difference equation $$x_{n+1}=\frac{x_{n}x_{n-3}}{Ax_{n-2}+Bx_{n-3}}, \quad n=0,1,...,$$ where $A, B>0$ and the initial values $x_{-i}$, $i\in\{0,1,2,3 ...

Exponential multivalued forbidden configurations [PDF]

Discrete Mathematics & Theoretical Computer Science, 2021
The forbidden number $\mathrm{forb}(m,F)$, which denotes the maximum number of unique columns in an $m$-rowed $(0,1)$-matrix with no submatrix that is a row and column permutation of $F$, has been widely studied in extremal set theory.

On a Rational $(P+1)$th Order Difference Equation with Quadratic Term

Universal Journal of Mathematics and Applications, 2022
In this paper, we derive the forbidden set and determine the solutions of the difference equation that contains a quadratic term \begin{equation*} x_{n+1}=\frac{x_{n}x_{n-p}}{ax_{n-(p-1)}+bx_{n-p}},\quad n\in\mathbb{N}_0, \end{equation*} where the ...

Enumeration of Circuits and Minimal Forbidden Sets [PDF]

Electronic Notes in Discrete Mathematics, 2003
In resource-constrained scheduling, it is sometimes important to know all inclusion-minimal subsets of jobs that must not be scheduled simultaneously. These so-called minimal forbidden sets are given implicitly by a linear inequality system, and can be interpreted more generally as the circuits of a particular independence system.

Set Families With a Forbidden Induced Subposet [PDF]

Combinatorics, Probability and Computing, 2012
For each posetHwhose Hasse diagram is a tree of heightk, we show that the largest size of a familyof subsets of [n]={1,. . .,n} not containingHas an induced subposet is asymptotic to$(k - 1)(\scriptsize{\begin{array}{c}{n}\\[-1.5pt] {\fl{n/2}} \end{array}})$.

Permutations realized by shifts [PDF]

Discrete Mathematics & Theoretical Computer Science, 2009
A permutation $\pi$ is realized by the shift on $N$ symbols if there is an infinite word on an $N$-letter alphabet whose successive left shifts by one position are lexicographically in the same relative order as $\pi$. The set of realized permutations is

Defects detection of floor tiles of ancient buildings based on Faster R-CNN

Dianzi Jishu Yingyong, 2021
Defect detection is of great significance for the protection and repair of ancient buildings. The traditional floor tile defect detection has been subject to visual inspection, which has limitations due to human influence and time-consuming. Based on the
