Understanding design: Artificial intelligence as an explanatory paradigm

Abstract

A substantial part of the intellectual content of what H A Simon called the 'sciences of the artificial' is contained in the activity we call desion. A central aim of desion theory is to construct testable, explanatory models of the design process that will serve to enhance our understanding of how artifacts are, or can be, designed. In this paper, we discuss how some of the basic concepts underlying the discipline of artificial inteUioence (AI) can serve to provide an explanatory paradiom for understanding design. We present an AI-based model of the design process and describe some of the implications of this model for our understanding of design-including that aspect of it we call 'invention'.

Finite element analysis and the stress correspondence paradigm

“…In this sense, a paradigm is a "framework of suppositions as to what constitutes problems, theories and solutions". It can be a collection of metaphysical assumptions, heuristic models, commitments, values, hunches, which are all shared by a scientific community and which provide the conceptual framework within which they can recognize problems and solve them (Dasgupta 1994). The DC and SC paradigms can be thought of as two competing scenarios which attempt to explain how the finite element method computes displacements, strains and stresses.…”

Mapeamento Da Função De Alargamento Doppler Deformada Através De Um Modelo De Temperatura Efetiva

“…O método proposto requer apenas 1,76% do tempo de computação gasto pelo método convencional de quadratura de Gauss Legendre [9]. Reduzir o tempo computacional em cálculos de reatores é muito importante em diversas metodologias que requerem centenas de cálculos de reatores em série, como é o caso da otimização de recarga de combustível com inteligência artificial [10,11,12,13]. Os combustíveis nucleares consistem em núcleos pesados que possuem estruturas nucleares complexas cujas seções transversais microscópicas possuem inúmeras ressonâncias.…”

“…Substituindo a equação (10) na equação (7), temos a seguinte expressão para a função de alargamento Doppler, 𝜓(𝑥, 𝜉):…”
