Comparison of picture fuzzy numbers (PFNs) are performed using score and accuracy values. But when both of the score and accuracy values are equal, those PFNs are said to be identical. This article presents a novel method to compare the PFNs even when the... see more

Decision Support System (DSS) is a computerized system used to help policy makers to make a decision. This system is used as a second opinion to assist decision making by combining complex data, models and analytical tools. There are various algorithms or... see more

AbstractPurpose: This exploratory study aimed to provide a description of the experiences and perceptions of survivalist entrepreneurs in under-resourced communities. These survivalist entrepreneurs perceived themselves as ‘temporary’ entrepreneurs. They ... see more

Decision making must of course be based on several factors that have a positive or no detrimental effect later. Therefore, careful calculations and considerations are required. This decision-making can occur in every human life, one of which is in decidin... see more

Density (?) and sound velocity (u) have been measured for aqueous solutions of n-butylamine ( W + NBA) in the whole range of composition at an interval of 5 K. Deviation in Sound Velocity (?u), Isentropic Compressibility (Ks), Excess Isentropic Compressib... see more

In this paper, by using the concept of belongingness (?) and quasi-coincidence (q) between fuzzy points and fuzzy sets, we introduce (a, ß)-fuzzy positive implicative ideals in BCK-algebras where a, ß are any of {?, q, ? V q, ? ^ q} with a ? ? ^ q.  

We discuss the existence of a positive solution to a given infinite semipositone problem.

A linear relationship between the standard enthalpy of formation from binary oxides, ?fHox, and the Goldschmidt tolerance factor, t, for some AIIBIVO3 (A = Ca, Sr, Ba; B = Ti, Zr, Hf, Ce, Pr, Tb, U, Pu, Am) perovskite oxides was used for estimation of ?fH... see more

In this article we study the existence of positive periodic solutions for a dynamic equations on time scales. The main tool employed here is the Schauder’s ?xed point theorem. The results obtained here extend the work of Olach [12]. Two examples are also ... see more
