Remarks on the Barthesian notion of punctum
No full textThis paper aims to be a compendium on the significance of images as an effective mediator in communication. The research work has resulted from the assumption that it is possible to think of the image as an intrinsically ethical mediator in communication. It has been amply demonstrated that the use of images can reach a level within a communication that is inherently ethical, able to take effective account of an otherness. There cannot exist, in this sense, a communication that is not an appeal, a search for the other, inside this kind of exchange, with full respect of the other's essence. A communication that makes use of images in an ethical manner will also be more immediate and certainly more effective. In order to address these issues, this paper's investigation has been deepened with the semiotics bibliography of French essayist Roland Barthes, with particular reference to those essays concerning a kind of poetics of the punctum, an analysis in relation to those images that are able to disrupt the relationship between observer and observed

Optimization criteria for tuned mass dampers for structural vibration control under stochastic excitation
No full textPerformance reliability based optimization criterion for elastic structures subject to random loads
No full textA stochastic optimization which makes use of a reliability constraint, expressing a performance requirement, is proposed for linear elastic systems subject to random dynamic loads. The criterion selected for the optimum design is the minimization of a deterministic measure, whereas the constraint condition requires that system failure probability must be smaller than a given allowable level, where failure is associated to the first exceeding of system response from a safe domain. The proposed method is then developed for the optimum design of a Tuned Mass Damper, utilized for reducing undesirable vibrations originated in structures by random loads. Unlike conventional TMD designs based on minimizing the mean-square response, a reliability-based performance measure is then considered in the proposed design, which properly accounts for uncertainties in loads. A sensitivity analysis is carried out and results are shown in a useful manner for TMD design decision suppor
