Effect of laser intensity profile on the microstructure and texture of Inconel 718 superalloy fabricated by direct energy deposition

Epitaxial growth of dendrites often results in a strong texture, which is a common phenomenon in a laser additive manufacturing process.In this study, pulsed lasers with flat-top and Gaussian intensity profiles were used to modulate the molten pool morphology and the solidification texture with a unidirectional scanning strategy.The melt pool is pl

Formal semantics for propositional attitudes

Contemporary logic is confined to a few paradigmatic attitudes such as VEGETARIAN OMEGA 3 belief, knowledge, desire and intention.My purpose is to present a general model-theoretical semantics of propositional attitudes of any cognitive or volitive mode.In my view, one can recursively define the set of all psychological modes of attitudes.As Descar
