Computational Aspects of Mechanism Design
In a preference aggregation setting, a group of agents must jointly make a decision, based on the individual agents’ privately known preferences. To do so, the agents need some protocol (or mechanism) that will elicit this information from them, and make the decision. Examples of such mechanisms include voting protocols, auctions, and exchanges. In most real-world settings, preference aggregati...
متن کاملFailure Processes in Embedded Monolayer Graphene under Axial Compression
Exfoliated monolayer graphene flakes were embedded in a polymer matrix and loaded under axial compression. By monitoring the shifts of the 2D Raman phonons of rectangular flakes of various sizes under load, the critical strain to failure was determined. Prior to loading care was taken for the examined area of the flake to be free of residual stresses. The critical strain values for first failur...
متن کاملA Cellular Automata Model for Predicting the Failure Pattern of Laterally Loaded Masonry Wall Panels
This paper introduces a new technique which directly predicts the failure patterns of laterally loaded masonry panels based on the results of existing typical panels tested in the laboratory. The technique is based on the use of the cellular automata (CA). In this technique, the CA modelling is established to propagate boundary effects to zones within a panel. The corresponding rules for the st...
متن کاملFailure of porous materials under compression: statistical aspects of labquakes
There are profound analogies between fracture experiments and earthquakes; however, few works attempt a complete characterization of the parallels between these so separate phenomena. We have studied the acoustic emission (AE) events produced during the compression of porous SiO2 (Vycor). The distribution of avalanche energies (Gutenberg-Richter law), the rate of aftershocks (modified Omori’s l...
متن کاملQuasi-static Axial Compression of thin-walled Circular Composite Tubes
Assessing the behavior of composite structures which are subjected to impact loads is one of the important subjects in the field of mechanical sciences. Using thin-walled tubes which collapsed and absorbed the impact energy is a well-known method to prevent damages to the other parts of the structures. In this paper, deformations, crushing length, peak load, mean force and energy absorption cap...
