2. A study of maximal and minimal ideals of n-refined neutrosophic rings

Mohammad Abobala

Volume 2, Issue 1 , Winter 2021, Pages 16-22

  If R is a ring, then Rn(I) is called a refined neutrosophic ring. Every AH-subset of Rn(I) has the form P = ∑ni=0 p i Ii= {a0+a1I+⋯+anIn: ai∈p i}, where p i are subsets of the classical ring R. The objective of this paper is to determine the necessary and sufficient conditions on p i which ...  Read More

3. Neutrosophic soft matrices and its application in medical diagnosis

Mamoni Dhar

Volume 2, Issue 1 , Winter 2021, Pages 23-32

  In real life situations, there are many issues in which we face uncertainties, vagueness, complexities and unpredictability. Neutrosophic sets are a mathematical tool to address some issues which cannot be met using the existing methods. Neutrosophic soft matrices play a crucial role in handling indeterminant ...  Read More

4. Neutrosophication of statistical data in a study to assess the knowledge, attitude and symptoms on reproductive tract infection among women

Somen Debnath

Volume 2, Issue 1 , Winter 2021, Pages 33-40

  Statistics mainly concerned with data that may be qualitative or quantitative. Earlier we have used the notion of statistics in the classical sense where we assign values that are crisp. But in reality, we find some areas where the crisp concept is not sufficient to solve the problem. So, it seems difficult ...  Read More

5. Interval type-2 fuzzy logic system for remote vital signs monitoring and shock level prediction

Uduak Umoh; Samuel Udoh; Abdultaofeek Abayomi; Alimot Abdulzeez

Volume 2, Issue 1 , Winter 2021, Pages 41-68

  Interval Type-2 Fuzzy Logic Systems (IT2 FLSs) have shown popularity, superiority, and more accuracy in performance in a number of applications in the last decade. This is due to its ability to cope with uncertainty and precisions adequately when compared with its type-1 counterpart. In this paper, an ...  Read More
