We discuss the specific type of uncertainty deriving from the non-uniform trustworthiness of Semantic Web style metadata sources, arguing toward the feasibility of modal possibilistic reasoning based on trust assertions expressing such uncertainty.

We present a concept of trust that integrates the truster’s goal, the trustee’s action that ensures the achievement of the truster’s goal, and the trustee’s ability and intention to do this action. This concept of trust is formalized in modal logic and is applied to the particular domain of trust in information sources. In this context trust may be derived, in particular, from the truster’s bel...

We propose a modal logic that supports reasoning about trust-based belief change. The term trust-based belief change refers to belief change that depends on the degree of trust the receiver has in the source of information.

Most past work on trustworthiness perception has focused on the structural features of the human face. The present study investigates the interplay of dynamic information from two channels – the face and the voice. By systematically varying the level of trustworthiness in each channel, 49 participants were presented with either facial or vocal information, or the combination of both, and made e...

in this study, the vibration of cracked plates is investigated using the differential quadrature method and experimental modal analysis. the crack, which is assumed to be open, is modeled by the extended rotational spring. with its finite length, the crack divides the plate into six segments. then, the differential quadrature is applied to the governing differential equations of motion and the ...
