https://jhs.uma.ac.ir/article_3032.html
Let R be an associative Noetherian unital noncommutative ring R. We introduce the functor P&Gamma;P over the category of R-modules and use it to characterize P-semiprime. P-semisecond R-modules also characterized by the functor P&Lambda;P. We also show that the Greenless-May Duality (GM) and Matlis Greenless-May Equality(MGM) hold over the full subcategory of R-Mod consisting of R-semiprime and R-semisecond modules. Finally, we generate a one-sided right ideal P&Gamma;P(R), which gives an equivalent formulation to solve K{\"o}the conjecture positively or negatively.The distance seidel spectrum of some graph operations
https://jhs.uma.ac.ir/article_3033.html
The distance matrix, distance eigenvalue, and distance energy of a connected graph have been studied in detail in literature where as the study on distance seidel matrix associated with a connected graph is in progress. The eigenvalues &part;1S&ge;&part;2S&ge; ... &ge;&part;nS of the distance seidel matrix DS(G) of a graph G forms the distance seidel spectrum of G. We describe here the distance seidel spectrum of some types of subdivision related graphs of a regular graph in terms of its adjacency spectrum. We also derive analytic expressions for the distance seidel energy of G(Cp), the partial complement of thesubdivision graph of a cycle Cp and the distance seidel energy of S(Cp), the complement of the even cycle C2p.Some properties of α−product on spherical fuzzy graphs
https://jhs.uma.ac.ir/article_3040.html
In a network model involves incomplete and imperfect network states for which sophisticated analysis is needed. Spherical fuzzy sets could be more helpful for the analysis of network state more accurately. The following evaluation information may be provided by the decision maker: Yes, Abstain; No, Reject. To solve such problems, we can use a mathematical model based on spherical fuzzy sets. The mathematical models are something like a theory which should be able to explain observations of making useful predictions. In this paper, some properties of &alpha;&minus;product on spherical fuzzy graphs are studied. Also, the regularity properties of &alpha;&minus;product of two spherical fuzzy graphs are discussed. Theorems related these concepts are stated and proved.Conformal Ricci soliton in Sasakian manifolds admitting general connection
https://jhs.uma.ac.ir/article_3041.html
The object of the present paper is to study the Conformal Ricci soliton in Sasakian manifold admitting general connection, which is induced with quarter symmetric metric connection, generalized Tanaka Webster connection, Schouten-Van Kampen connection and Zamkovoy connection. Furthermore, we study CG-semi symmetric and CG-semi symmetric Sasakian manifolds admitting Conformal Ricci Soliton.A statistical study on structures of patient privacy in Iran and their violations
https://jhs.uma.ac.ir/article_3044.html
The aim of all the studies that have been conducted on the concept of patient privacy is to improve the standards of care. Personal privacy is a basic human principle and as a fundamental right of every human being, it is an important and necessary requirement that must be observed in health care and nursing organizations. Due to the fear of emerging and contagious diseases and the patients' fear of rejection from their families and in a wider sense of society, they hesitate to express the symptoms of contagious diseases as a social stigma, and this issue itself leads to disruption in It becomes the treatment process of the patients and doubles the importance of preserving the privacy of the patients. \linebreak Considering the many and abnormal consequences of violating the patient's privacy, such as increasing anxiety, stress, inciting aggressive and violent behaviors, and more importantly, hiding parts of the patient's history or medical history due to the concern of violating their privacy. This research will be conducted with the aim of investigating the level of privacy compliance and its related factors in corona patients of Razi Hospital in Rasht city in 2022.Some results on Bayes estimation under Linex loss function
https://jhs.uma.ac.ir/article_3045.html
In this paper, we introduced straightforward formulas for the Bayes risk linked to the Linex loss function, which we then applied to estimate parameters of the normal, Poisson, and fractional Weibull distributions.We aimed to investigate the development of a linear Bayes estimator using the Linex loss function and successfully derived it for the normal and Poisson scenarios.We also demonstrated the process of creating empirical Bayes estimates using Linex loss and applied it to observed frequencies fn(x)$ produced by the Poisson-gamma model.Convergence of Panigrahy iteration process for Suzuki generalized nonexpansive mapping in uniformly convex Banach space
https://jhs.uma.ac.ir/article_3046.html
In this paper, we establish strong and weak convergence theorems for Suzuki's generalized nonexpansive mapping in uniformly convex Banach spaces using the iterative scheme introduced by Panigrahy et al [9]. Next, we see an example of Suzuki's generalized nonexpansive mapping, which is not a nonexpansive mapping. Using this example and some numerical tests, we infer empirically that the Panigrahy iteration process converges faster than the Krasnoselskij, Thakur, and M-iteration processes.Approach to fuzzy differential equations in Intuitionistic fuzzy metric spaces using generalized contraction theorems
https://jhs.uma.ac.ir/article_3049.html
Approach to fuzzy differential equations in fuzzy metrics using generalized contra ction theorems One of the most fascinating fields of mathematical inquiry is fixed point.In this direction, by utilizing &rdquo;the triangular property of fuzzy metric &rdquo;, we investigate certain special common fixed point solutions for a pair of self mappings without continuity on fuzzy metric spaces under the generalized contraction requirements. We also provide generalized Ciri&rsquo;s c contraction theorems and weak contraction theorems. The findings are corroborated by pertinent cases. Additionally, we provide a workable application of the fuzzy differential equation s to guarantee the presence of a singular common solution to support our primar y researchSome fixed point theorem uses intimate mappings to produce intuitionistic fuzzy metric space
https://jhs.uma.ac.ir/article_3066.html
The aim of this research paper to use the concept of Intimate mappings to demonstrate the existence and uniqueness of common fixed point theorems for self-mappings in intuitionistic fuzzy metric space. The goal of this research work is to prove the existence and uniqueness of common fixed point theorems for selfmappings in intuitionistic fuzzy metric space using the notion of intimate mappingsOn Cartan torsion of 4-dimensional Finsler manifolds
https://jhs.uma.ac.ir/article_3071.html
There are several non-Riemannian curvatures in Finsler geometry which show the complexity of Finsler geometry with respect to Riemannian geometry. Amon these quantities, the Cartan and mean Cartan torsion have very important and brilliant positions. In this paper, we find the necessary and sufficient condition under which a 4-dimensional Finsler manifold is C-reducible. Also, we find the necessary and sufficient condition under which a 4-dimensional Finsler manifold has vanishing ${\bar I}$-curvature.Python approach on fuzzy time series Arima (1, 1, 1) model to analyze original and predict results for online retail of fuel booking services
https://jhs.uma.ac.ir/article_3095.html
This paper contributes to modeling and forecasting gas booking demand in an online retail environment using time series techniques. Our work demonstrates how historical demand data can be utilized to estimate future demand and its impact on the supply chain. The historical demand data were used to create several autoregressive integrated moving average (ARIMA) models using the Box-Jenkins time series procedure. The best model was selected based on four performance criteria: statistical results, maximum likelihood, and standard error. The selected model, ARIMA (1, 1, 1), was validated using additional historical demand data under the same conditions. The results demonstrate that the model can effectively estimate and forecast future demand for gas booking in an online retail environment. These findings will provide trustworthy guidance to the company's management in decision-making.
