MULTICRITERIA OPTIMAL DESIGN OF CONTINUOUS CIRCULAR PLATES
2010
The paper is devoted to a quite general version of the multicriteria optimal (minimum volume) design of axisymmetric circular plates. The constitutive material is considered as elastic perfectly plastic without any ductility limit and the actions are assumed as quasi-statically variable within a given load domain. In the design problem formulation different resistance criteria are considered, in order to investigate all the possible structural limit responses, and for each one a suitably chosen safety factor is chosen. The optimal design problem is formulated as the search for the minimum structure volume according with a statical approach. The features of the optimal structures will be stu…
Reliable measures of plastic deformations for elastic plastic structures in shakedown conditions
2020
A new formulation for evaluating reliable measures of the plastic deformations occurring in the transient phase of a structure in shakedown conditions is proposed. The structure is thought as constituted by elastic perfectly plastic material and subjected to a combination of fixed and cyclic loads. The proposed formulation consists in the search for the optimal plastic strain field that minimize a suitable objective function defining a strain energy measure related to the plastic strains at the shakedown limit. The typical self-stress field can be obtained as the elastic structural response to an assigned plastic strain field respecting appropriate ductility limits for the material. Without…
Influence of protecting devices on the optimal design of elastic plastic structures
2008
The paper concerns the minimum volume design of structures constituted by elastic perfectly plastic material. The relevant optimal design problem is formulated on the grounds of a statical approach and two different resistance limits are considered: in particular, it is required that the optimal structure satisfies the elastic shakedown limit and the instantaneous collapse limit, imposing for each different condition a suitably chosen safety factor. For sake of generality, the structure is thought as discretized into compatible finite elements and subjected to loads quasi-statically acting as well as to dynamic (seismic) loads. The effects of the dynamic actions are studied on the grounds o…
Optimising the efficiency of olive harvesting considering operator safety
2019
Mechanical-assisted harvesting of olives, which is carried out using hand-held harvesting units that detach the drupes through vibration supplied by electric motor or combustion engines, is a widespread method used in southern Italy. Such machines are able to harvest more than 80% of the overall quantity of olives available per tree in 5–10 min, but their performance is influenced by several factors related to the mechanical characteristics of the device and to the features of the trees. Here the problem of optimising harvesting efficiency whilst minimising the health risks to the operators is investigated, with the aim of demonstrating that it is possible to determine an optimum harvesting…
Monstrous Hybrids in Shakespeare’s King Lear
2017
ABSTRACT: This article seeks to present the different languages (emblems, Renaissance translations of classical myths, biblical exegesis) that inform the images of monsters which, as hybrid creatures blending human and animal characteristics, serve a dramatic function in Shakespeare’s King Lear . It means to question the ways in which the play links filial ingratitude with female monstrosity and Lear’s madness. Tracing the classical and medieval lineage of the monstrous bestiary (serpent, tiger, vulture) in King Lear and connecting it to emblematic readings of Shakespeare’s time, it explores how Shakespeare provides a dynamic characterisation of Goneril and Regan through their bestialisatio…
Gallivanting Round the Globe: Translating National Identities in Henry V
2012
In this article we shall be looking at the character of MacMorris in Henry V, and at his small but important role in the four captains’ scene. We shall explore some of the historical, cultural, political, dramaturgical and linguistic complexities of his portrayal of Irishness as a necessary preliminary study to its translation into other languages, both for the printed page and for the stage. Spanish and Catalan translations of the scene will be briefly analysed in what we hope will be the framework of a wider, multilingual preoccupation: how does national identity translate in a global context? How does —or can— MacMorris speak in other languages?
Vindicating Pablo Avecilla’s Spanish ‘Imitation’ of Hamlet (1856)
2012
This essay examines Pablo Avecilla’s Hamlet, an ‘imitation’ of Shakespeare’s tragedy of the prince of Denmark published in 1856, both in its own terms and in the historical context of its publication. This Shakespearean adaptation has been negatively judged as preposterous and unworthy of comment, but it deserves to be approached as what it claimed to be, a free handling of the Shakespearean model, and as responding to its own cultural moment. Avecilla turns the Shakespearean sacrificial prince into a righteous sovereign that has kept the love of a lower-ranked lady and, by pursuing revenge, has successfully overthrown a dishonourable and corrupt ruler. This re-focusing of the Shakespearean…
An AER handshake-less modular infrastructure PCB with x8 2.5Gbps LVDS serial links
2014
Nowadays spike-based brain processing emulation is taking off. Several EU and others worldwide projects are demonstrating this, like SpiNNaker, BrainScaleS, FACETS, or NeuroGrid. The larger the brain process emulation on silicon is, the higher the communication performance of the hosting platforms has to be. Many times the bottleneck of these system implementations is not on the performance inside a chip or a board, but in the communication between boards. This paper describes a novel modular Address-Event-Representation (AER) FPGA-based (Spartan6) infrastructure PCB (the AER-Node board) with 2.5Gbps LVDS high speed serial links over SATA cables that offers a peak performance of 32-bit 62.5…
Dynamic shakedown of structures under repeated seismic loads
1995
Elastic, perfectly plastic structures are considered under the action of repeated short-duration exitations of seismic type acting in an unknown time sequence, but belonging to a given polyhedral excitation domain. The basic excitations (vertices of the polyhedron) are chosen as discrete-spectrum waves each with frequencies coincident with the first natural frequencies of the structure, and amplitudes related to the ground features and earthquake intensity (according to the Kanai and Tajimi filter model) in such a way that every admissible excitation-obtained as a linear convex combination of the basic ones-has a maximum power not exceeding a given value. In the framework of unrestricted dy…
National e-resources of Shakespeare translations in Europe: (Dis)assembling the black box
2019
This article discusses the construction, operation and scholarly usefulness of electronic resources of Shakespeare translations. In particular, it offers an overview of several existing European digital resources of Shakespeare translations by singling out trends, challenges and new vistas of research; describing the content, editing policies and functionalities of selected European projects, already in operation or currently assembled; and discussing the aims and major difficulties faced by the researchers, the choice of navigation and search tools, the possibilities of integrating national repositories with other resources and the relation of translation e-resources to adjacent disciplin…
