In this work we construct linear orders between pairs of intervals by using aggregation functions. We apply these orders in a decision-making problem where the experts provide their opinions by means of interval-valued fuzzy sets.

A right module M over an associative ring with unity is a QTAG-module if every finitely generated submodule of any homomorphic image of M is a direct sum of uniserial modules. In this paper we find a suitable condition under which a special ω-elongation of a summable QTAG-module by a ( ω +k)-projective QTAG-module is also a summable QTAG-module.

We consider voting games as procedures to aggregate individual preferences. We survey positive results on the non-emptiness of the core of voting games and explore other solutions concepts that are basic supersets of the core such as Rubinstein’s stability set and two types of uncovered sets. We consider cases where the sets of alternatives are ‘ordinary’ sets, finite sets and infinite sets wit...

This paper investigates U.S. bank common stock returns and their sensitivity to market risk, interest rate risk, and illiquidity risk. Due to known problems with conducting inference using Generalized Method of Moments, I use the Empirical Likelihood Block Bootstrap established in Allen, Gregory, and Shimotsu (2004). Preliminary results suggest that once the test-statistics are bootstrapped, ag...

s of the 3 MC-GARD Meeting, 1-5 April 2009: Friday 3 April 96 discuss the aggregate data, which in sum moves toward defining the molecular architecture of a complex we refer to as the insulatosome.

In this paper we provide a way to generate a class of weighted average operator from n-dimensional overlap functions and aggregation functions. These weighted average operators are used in an algorithm of a multiattribute group decision making problem based on decision matrix. An illustrative example is considered with the application of our method for two specific weighted average operators of...

Thus, for each student a composite unscaled mark is generated for each course taken. However, the cohort of students taking a particular course P may be academically more able than the cohort of students taking course Q. This means that a composite unscaled mark of, say, 60 in course P represents a higher level of attainment than the same mark in course Q. Since marks in different courses are a...

This article discusses Lipschitz properties of generated aggrega-tion functions. Such generated functions include triangular norms and conorms, quasi-arithmetic means, uninorms, nullnorms and continuous generated functions with a neutral element. The Lipschitz property guarantees stability of aggregation operations with respect to input inaccuracies, and is important for applications. We provid...

This paper discusses the use of semantic technologies to increase quality, machine-processability, format translatability and crossquerying of complex tabular datasets. Our interest is to enable longitudinal studies of social processes in the past, and we use the historical Dutch censuses as case-study. Census data is notoriously difficult to compare, aggregate and query in a uniform fashion. W...
