Modeling the effect of quarantine and hospitalization on the spread of COVID19 during the toughest period of the pandemic
(20230101)The year 2020 arrives with COVID19. The pandemic poses a formidable threat to human existence at onset but is fought with various measures of which quarantine and hospitalization play a key role. In this article, a COVID19 ...

Higher Homomorphisms and Their Approximations
(20230101)In this paper, we introduce a class of higher homomorphisms on an algebra $ \mathcal{A} $ and we characterize the structure of them as a linear combination of some sequences of homomorphisms. Also we prove that ...

The small intersection graph of filters of a bounded distributive lattice
(20230101)Let $L$ be a lattice with $1$ and $0$. The small intersection graph of filters of $L$, denoted by $\Gamma(L)$, is defined to be a graph whose vertices are in one to one correspondence with all nontrivial filters of $L$ ...

Chlodowsky type $\left( \lambda,q\right)$Bernstein Stancu operators of Pascal rough triple sequences
(20230101)The fundamental concept of statistical convergence first was put forward by Steinhaus and at the same time but also by Fast \cite{Fast} independently both for complex and real sequences. In fact, the convergence in terms ...

CostAware and EnergyEfficient Task Scheduling Based on Grey Wolf Optimizer
(20230101)One of the principal challenges in the cloud is the task scheduling problem. Appropriate task scheduling algorithms are needed to achieve goals such as load balancing, minimum cost, minimum energy consumption, etc. Using ...

Designing a new case of twostage DEA Model about the indirect relation of Information Technology investment on firm performance in Intuitionistic Fuzzy Environment
(20230101)Data Envelopment Analysis (DEA) is a theoretical framework for performance analysis and efficiency measurement. Traditional DEA models, which measure the efficiency of simple decisionmaking with multiple inputs and outputs, ...

Comparison between Mathematical ProblemSolving Approach Under Iranian and Iraq Teachers' Views
(20230101)Being mainly a process of knowledge transmission, mathematics education evolves during time in accordance with the strong assumptions and beliefs which are considered as parts of the mathematics teaching profession. This ...

Vortex Solutions for Thermohaline circulation Equations
(20230101)The main objective of this article is to establish a new model and find some vortex axisymmetric solutions of finite core size for this model. We introduce the hydrodynamical equations governing the atmospheric circulation ...

Stability and Hopf bifurcation analysis of a chaotic system using timedelayed feedback control method
(20230101)In this paper, we study the effect of delayed feedback on the dynamics of a threedimensional chaotic dynamical system and stabilize its chaotic behavior and control the respective unstable steady state. We derive an ...

Forecasting educated unemployed people in Indonesia using the Bootstrap Technique
(20230101)Forecasting is an essential analytical tool used to make future predictions based on preliminary data. However, the use of small sample sizes during analysis provides inaccurate results, known as asymptotic forecasting. ...

Equalizers and Coequalizers in the Category of Topological Molecular Lattices
(20230101)A completely distributive complete lattice is called a molecular lattice. It is well known that the category TML of all topological molecular lattices with generalized order homomorphisms in the sense of Wang, is both ...

The Complete Classification of QuarterSymmetric Magnetic Curves in Smanifolds
(20230101)In this paper, we consider $S$manifolds endowed with a quartersymmetric metric connection. We obtain the condition for a curve to be magnetic with respect to this connection. We show that quartersymmetric magnetic curves ...

Metallic structures on tangent bundles of Lorentzian paraSasakian manifolds
(20230101)Let M be a Lorentzian paraSasakian manifold with a Lorentzian paraSasakian structure (φ,η,ξ,g). In this paper, we introduce some metallic structures on tangent bundle of the manifold M using vertical, horizontal and ...

Recognition of the direct products of Suzuki groups by their complex group algebras
(20230101)Denote by $\widehat{p_n}$, the largest prime among the primitive prime divisors of $ 2^{2n+1}1 $ and $ 2^{2(4n+2)}1 $, where $n\in {\Bbb N}$. In this paper, we prove that if $ q=2^{2n+1}\geq8 $ and $\alpha \leq \widehat{p_n}$, ...

The fuzzy D'Alembert solutions of the fuzzy wave equation under generalized differentiability
(20230101)In this paper, a onedimensional homogeneous fuzzy wave equation is solved with an analytical procedure using the fuzzy D'Alembert method by considering the generalized differentiability. Then, some definitions related to ...

Inference in Univariate and Bivariate Autoregressive Models with NonNormal Innovations
(20230101)In this paper we consider the estimation, order and model selection of autoregressive time series model which may be driven by nonnormal innovations. The paper makes two contributions. First, we consider the method ...

Some results on the open locatingtotal domination number in graphs
(20230101)In this paper, we generalize the concept of an open locatingdominating set in graphs. We introduce a concept as an open locatingtotal dominating set in graphs that is equivalent to the open neighborhood locatingdominating ...

On lower bounds for the metric dimension of graphs
(20230101)For an ordered set $W=\{w_1, w_2,\ldots,w_k\}$ of vertices and a vertex $v$ in a connected graph $G$, the ordered $k$vector $r(vW)=(d(v,w_1),d(v,w_2),\ldots,d(v,w_k))$ is called the (metric) representation of ...
