Fuzzy Signal Detection Theory (FSDT) has the potential of enhancing performance measures in detection tasks in which precision of Signal Detection Theory (SDT) analysis is limited by discrete mutually exclusive categorization of the state of the world and/or responses available to the observer. While there have been empirical efforts to demonstrate the benefits and tenability of FSDT, the quest...

Fuzzy Signal Detection Theory (FSDT) combines traditional Signal Detection Theory (SDT) with Fuzzy Set Theory to generalize signal detection analysis beyond the traditional categorical decision-making model. This advance upon SDT promises to improve measurement of performance in domains in which stimuli do not fall into discrete, mutually exclusive categories; a situation which characterizes ma...

A recent advance upon Signal Detection Theory (SDT) promises to enhance measurement of performance in complex real world domains where stimuli do not fall into discrete, mutually exclusive categories. This development, Fuzzy Signal Detection Theory (FSDT) combines traditional SDT with Fuzzy Set Theory (FST) to extend signal detection analysis beyond the traditional crisp, categorical decision m...

A recent advance on Signal Detection Theory (SDT) promises to enhance measurement of performance in complex real world domains. This development, Fuzzy Signal Detection Theory (FSDT), combines traditional SDT with Fuzzy Set Theory to extend signal detection analysis beyond the traditional crisp, categorical model. FSDT permits events to simultaneously be in more than one state category (e.g. si...

This report presents the results of an experimental study that was conducted to investigate the effects of key parameters on the compressive behavior of fiber reinforced polymer (FRP)concrete-steel double-skin tubular columns (FSDT). Hybrid FSDT columns have been introduced as a new form of hybrid columns. They consist of an outer tube made of FRP and inner tube made of steel, with sandwiched c...

The effect of response set size on performance on a detection task was evaluated using both fuzzy and traditional signal detection theory. Fuzzy categories of stimuli were created using morphing software to blend profile images of American (M1A1) and Iraqi (T55) tanks to different degrees. These combinations were used to create static images varying from 100% T55 to 0% T55 (100% MIA1). Particip...

Nonlinear plate bending within Mindlin's strain gradient elasticity theory (SGT) is investigated by employing somewhat non-standard finite element methods. The main goal to compare the results provided geometrically nonlinear three-dimensional (3D) and Reissner–Mindlin theory, i.e., first-order shear deformation (FSDT), SGT. For 3D Green–Lagrange relations are adopted, while von Kármán strains ...

Abstract In this study, the first-order shear deformation theory (FSDT) is used to establish a nonlinear dynamic model for conical shell truncated by functionally graded graphene platelet-reinforced composite (FG-GPLRC). The vibration analyses of FG-GPLRC are presented. Considering platelets (GPLs) with three different distribution patterns, modified Halpin-Tsai calculate effective Young’s modu...

This article presents the derivation of elastic buckling equations and boundary conditions shear-deformable plates in frame extended Kantorovich method (EKM). Surveying literature shows that those stability are often obtained using a wrong by confusing them with linear equilibrium condition. work aims at providing correct is built on Buckling derived for three different plate theories, namely, ...
