Abstract

The best mathematical tools for combining numerous inputs into a single result are aggregation operators. The aggregation operators work to combine all of the individual evaluation values provided in a uniform form, and they are very useful for evaluating the options provided in the decision-making process. To provide a larger space for decision makers, complex q -rung orthopair fuzzy rough sets can express their uncertain information. As a generalization of the algebraic operations, the Einstein t -norm and t -conorm, Hamacher operations have become significant in aggregation theory. The Hamacher aggregation operator's major characteristic is that it can capture the interrelationship between several input arguments. In this article, some Hamacher aggregation operators for complex q -rung orthopair fuzzy rough sets are presented. We define a complex q -rung orthopair fuzzy rough Hamacher operation laws and a new score function. In addition, we propose a serious of averaging aggregation operators for complex q -rung orthopair fuzzy rough set. We present the essential properties of these operators. We use the defined operators and modified EDAS (evaluation based on distance from average solution) method to propose an approach for solving a multicriteria decision making problem. To demonstrate the practicality and effectiveness of our propose model, we consider a numerical example of area selection for an arboretum. Finally, a comparison between the suggested approach with existing operators has been presented for authenticity and reliability. [ABSTRACT FROM AUTHOR]

Abstract

Background: (ABO) Blood type has an effect on general health including oral health. Dental caries are the common infectious disease of the mouth. Saliva plays significant roles in oral cavity; for example, salivary immunoglobulin’s play important role in immunity of the body and the mouth. Various studies conducted on the different effects of IgA on oral cavity, especially dental caries, and found controversial results. The aim of the current study is to assess of the prevalence of caries experience among different blood type in relation to salivary IgA. Materials and Methods: Two hundred and nine students in college of dentistry, Baghdad University aged 20 years old were selected; they were divided to four groups regarding to their blood type, Dental experience was diagnosed and recorded according to DMFs Index, this allows recording decayed lesion by severity. Saliva sample pooled for analysis. Results: In the current study the blood type O was more common followed by A and B, whereas the less common was AB type, also the present study found only few students with AB-. Caries experiences (DMFs) found to be statistically significant among different blood types, since DMFs was higher among type AB and lowest among A blood type. Level of salivary IgA was high among blood type O and low among blood type AB. Also its level among blood group with Rh- higher than that with Rh+. Finally, this study found that there is inverse relation between dental caries and salivary IgA. Conclusion: ABO blood type and Rh have an effect on prevalence of caries and level of IgA in saliva.

Abstract

In current piece of writing, we bring in the new notion of induced bipolar neutrosophic (BN) AOs by utilizing Einstein operations as the foundation for aggregation operators (AOs), as well as to endow having a real-world problem-related application. The neutrosophic set can rapidly and more efficiently bring out the partial, inconsistent, and ambiguous information. The fundamental definitions and procedures linked to the basic bipolar neutrosophic (BN) set as well as the neutrosophic set (NS), are presented first. Our primary concern is the induced Einstein AOs, like, induced bipolar neutrosophic Einstein weighted average (I-BNEWA), induced bipolar neutrosophic Einstein weighted geometric (I-BNEWG), as well as their different types and required properties. The main advantage of employing the offered methods is that they give decision-makers a more thorough analysis of the problem. These strategies whenever compare to on hand methods, present complete, progressively precise, and accurate result. Finally, utilizing a numerical representation of an example for selection of robot, for a problem involving multi-criteria community decision making, we propose a novel solution. The suitability ratings are then ranked to select the most suitable robot. This demonstrates the practicality as well as usefulness of these novel approaches.

Abstract

In this paper, an efficient technique called Optimal Homotopy Asymptotic Method has been extended for the first time to the solution of the system of fuzzy integro-differential equations of fractional order. This approach however, does not depend upon any small/large parameters in comparison to other perturbation method. This method provides a convenient way to control the convergence of approximation series and allows adjustment of convergence regions where necessary. The series solution has been developed and the recurrence relations are given explicitly. The fuzzy fractional derivatives are defined in Caputo sense. It is followed by suggesting a new result from Optimal Homotopy Asymptotic Method for Caputo fuzzy fractional derivative. We then construct a detailed procedure on finding the solutions of system of fuzzy integro-differential equations of fractional order and finally, we demonstrate a numerical example. The validity and efficiency of the proposed technique are demonstrated via these numerical examples which depend upon the parametric form of the fuzzy number. The optimum values of convergence control parameters are calculated using the well-known method of least squares, obtained results are compared with fractional residual power series method. It is observed from the results that the suggested method is accurate, straightforward and convenient for solving system of fuzzy Volterra integrodifferential equations of fractional order.

Abstract

In this paper, we introduce a new sort of interval valued ∈, ∈ Vq...)-fuzzy bi-ideal in ordered semigroups which is the generalization of interval valued (∈,∈ Vqk)-fuzzy bi-ideal and interval valued (∈, ∈ Vq)-fuzzy bi-ideal of ordered semigroups. We give examples in which we show that these structures are more general than previous one. Finally, we characterize ordered semigroup by the property of interval valued (∈, ∈ Vq...)-implication based fuzzy bi-ideals. [ABSTRACT FROM AUTHOR]
