A method to compute the transitive closure, a transitive opening and a transitive approximation of a reflexive and symmetric fuzzy relation is given. Other previous methods in literature compute just the transitive closure, some transitive approximations or some transitive openings. The proposed algorithm computes the three different similarities that approximate a proximity for the computation...

Abstract—The Analytic Hierarchy Process is frequently used approach for solving decision making problems. There exists wide range of software programs utilizing that approach. Their main disadvantage is that they are relatively expensive and missing intermediate calculations. This work introduces a Microsoft Excel add-in called DAME – Decision Analysis Module for Excel. Comparing to other compu...

The Boston University Henry M. Goldman School of Dental Medicine (BUSDM) initiated a program in the summer of 1993 to strengthen diversity in the entering class of first-year students. The Experiential Center for Excellence in Learning (EXCEL) Program is a voluntary, one-month-long prematriculation experience that combines didactic, laboratory, study skills, and social activities to prepare par...

This work shows how Excel can be leveraged to tackle configuration problems. We demonstrate this by presenting the full development cycle of a PC-configurator prototype. We articulate our demonstration by exemplifying several important points. First, Excel can be used to import raw products and services data. Second, these data can be used by a constraint modelling to correctly instantiate a se...

The development of a reliable power filter is essential for meeting the need high-quality power. Current and voltage harmonics are major contributor to poor quality must be eliminated. Shunt active filters (SAPFs) can installed reduce negative effects harmonics. Fuzzy logic proportional integral (PI) controllers excel at regulating DC link in shunt (SAPFs). This research assessed how well Parti...

There are many situations where input feature vectors are incomplete and methods to tackle the problem have been studied for a long time. A commonly used procedure is to replace each missing value with an imputation. This paper presents a method to perform categorical missing data imputation from numerical and categorical variables. The imputations are based on Simpson’s fuzzy min-max neural ne...

This paper deals with the group decision making problem, assuming that each individual defines his/her opinion through fuzzy binary preference relations, in parallel to the classical approach due to Prof. Arrow. In particular, it is postulated that the main reason for the discouraging impossibility theorems is neither in the domain of admissible preferences or in the concept of solution (Social...

Multichannel signal processing using digital signal processing techniques has received increased attention due to its importance in different information technology applications such as mul-timedia technology and telecommunications. Our objective in this paper is to provide a review for the reader who may be well versed in DSP, and to introduce some existing fuzzy (or fuzzy related) filtering t...
