Un'applicazione della teoria dei semigruppi ordinati nell'ambito della teoria delle decisioni

open access: yesLe Matematiche, 1996
In this paper we introduce in the semigroup S, whose elements are to be evalued in terms of preference in a particular situation, a pre-order defined through semigroups of S.

An algorithm to compute the transitive closure, a transitive approximation and a transitive opening of a proximity

open access: yes
A method to get the transitive closure, a transitive opening and a transitive approximation of a reflexive and symmetric fuzzy relation is presented.

To vary or not to vary: A flexible empirical Bayes factor for testing variance components

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Random effects are the gold standard for capturing structural heterogeneity, such as individual differences or temporal dependence. Yet testing their presence is difficult because variance components are constrained to be non‐negative, creating a boundary problem. This paper introduces a flexible empirical Bayes factor (EBF) for testing random

Connections between the basic local independence model and true and error models in the study of preference

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Two classes of probabilistic models are compared: the true and error (TE) type models and models in the family of the basic local independence model (BLIM). The former finds applications in the study of human preference, whereas the latter has been developed within the theory of knowledge structures with the aim of producing knowledge ...

An uncomplicated introduction to representational measurement theory

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Measurement in psychology is often associated with psychometrics. Despite the theoretical insights afforded by psychometric methods, they represent only a restricted range of possible measurement approaches in the social sciences. Representational measurement theory (RMT) generalizes the logic of measurement developed in the physical sciences ...

Volume Quantization with Flexible Singularities for Hexahedral Meshing

open access: yesComputer Graphics Forum, EarlyView.
Abstract We present a novel algorithm for quantization and subsequent hexahedral mesh generation from seamless volumetric maps. Quantization is the process of choosing integers that represent the numbers of hexahedral elements to be placed in each region of the volume, and transforming the seamless map into an integer‐grid map matching that choice ...

Clusterix: A Hybrid Visualization Model for Hierarchically Clustered Networks

open access: yesComputer Graphics Forum, EarlyView.
Abstract We introduce Clusterix, a novel hybrid visualization model for representing hierarchically clustered networks, which also supports directed and weighted edges. Clusterix offers an integrated view of both the network and its full cluster hierarchy by compactly visualizing the cluster inclusion tree enriched with links of the network.

A Novel Approach to Decision-Making Under Uncertainty Using Spherical Linear Diophantine Fuzzy Relations

open access: yesJournal of Mathematics
Fuzzy relations are more advanced than crisp binary relations, which are applicable in control systems in artificial intelligence. Our research study develops a fuzzy spherical linear Diophantine fuzzy SLDFu relation as a more advanced tool to handle ...

The Story(line) So Far: A Survey on Storyline Visualization

open access: yesComputer Graphics Forum, EarlyView.
Abstract Storyline visualizations model narratives as temporal networks, using x‐monotone lines to represent entities and their interactions over time. This technique offers an intuitive way to reveal structural patterns over time, such as character co‐occurrence and narrative flow.

Executable Transitive Closures

open access: yes, 2012
We provide a generic work-list algorithm to compute the (reflexi-ve-)transitive closure of relations where only successors of newly de-tected states are generated.
