Simulation of ultrasonic lamb wave generation, propagation and detection for an air coupled robotic scanner
No full textA computer simulator, to facilitate the design and assessment of a reconfigurable, air-coupled ultrasonic scanner is described and evaluated. The specific scanning system comprises a team of remote sensing agents, in the form of miniature robotic platforms that can reposition non-contact Lamb wave transducers over a plate type of structure, for the purpose of non-destructive evaluation (NDE). The overall objective is to implement reconfigurable array scanning, where transmission and reception are facilitated by different sensing agents which can be organised in a variety of pulse-echo and pitch-catch configurations, with guided waves used to generate data in the form of 2-D and 3-D images. The ability to reconfigure the scanner adaptively requires an understanding of the ultrasonic wave generation, its propagation and interaction with potential defects and boundaries. Transducer behaviour has been simulated using a linear systems approximation, with wave propagation in the structure modelled using the local interaction simulation approach (LISA). Integration of the linear systems and LISA approaches are validated for use in Lamb wave scanning by comparison with both analytic techniques and more computationally intensive commercial finite element/difference codes. Starting with fundamental dispersion data, the paper goes on to describe the simulation of wave propagation and the subsequent interaction with artificial defects and plate boundaries, before presenting a theoretical image obtained from a team of sensing agents based on the current generation of sensors and instrumentation

The Violence of the Lamb: Martyrs as Agents of Divine Judgement in the Book of Revelation
No full textLibrary of New Testament Studies 586The act of martyrdom in the worldview of the Apocalypse has been considered to be an exemplification of non-violent resistance. Paul Middleton argues here, however, that it is in fact a representation of direct participation by Christians, through their martyrdom, in divine violence against those the author of Revelation portrays as God's enemies. Middleton shows that acceptance of martyrdom is to grasp the invitation to participate in the Revelation's divine violence. Martyrs follow the model laid down by the Lamb, who was not only slain, but resurrected, glorified, and who executes judgement. The world created by the Apocalypse encourages readers to conquer the Beast through martyrdom, but also through the experience of resurrection and being appointed judges. In this role, martyrs participate in the judgement of the wicked by sharing the Lamb's power to judge. Different from eschewing violence, the conceptual world of the Apocalypse portrays God, the Lamb, and the martyrs as possessing more power, might, and violent potential than the Emperor and his armies. Middleton believes that martyrdom and violence are necessary components of the worldview of Revelation
