Algorithmic issues for the two thermodynamically consistent viscoplastic formulations of Perzyna and Duvaut–Lions are discussed. It is shown that it is simple to avoid the numerical problems associated with a small relaxation time without resorting to elaborate perturbation techniques, as suggested in the literature. A systematic numerical investigation of the efficiency of Newton iterations, that

Abstract: This paper provides one of the first studies on the role of social media in shaping collective memory in contemporary China. Social media enable the ordinary to participate in creating, interacting, and distributing alternative narratives of the past. Therefore, collective memory has being reconfigured under the influence of social media. Nevertheless, previous collective memory studies
In this paper the spectral features of impulse noise in DSL systems are mapped from the waveform domain onto the symbol domain, considering a QAM receiver. This work can be viewed as part of a full symbol domain model for impulse noise, which should include the amplitude and spectral aspects. Since the available models of impulse noise in DSL are generally waveform-based, this kind of mapping is j
In this thesis we have performed a systematic atomic scale characterization of model catalysts under pressures ranging from UHV to atmospheric ambient. By using a unique approach, linking UHV and high pressures studies by combining traditional electron based techniques with novel high pressure in situ probes and ab initio calculations, the surface structure of the different model catalysts could b
The first part of the essay attempts to advance the idea that animals can, like humans, become subjects of genuine bonds of attachment. The second part of the essay examines how interventions to protect, care for, or save animals, interface with various forms of alterity - related to what socially and physiologically constitutes ‘being human’ and ‘being animal’.This essay provides a frame for a di
In this paper a synchronized dual input-channel multi-mode Software Defined Radio receiver platform that we built originally is presented. The receiver platform compatible with the GSM, WCDMA, and Wi-Fi standards can detect and identify the surrounding base stations and access points. It features wide frequency range, high adaptive sampling rate and especially dual phase coherent receiving channel
