A model for corrosion crack nucleation and growth is presented, where the corrosion forms the geometry of the crack tip, thus creating the conditions for strain concentration. The interaction between electro chemical processes and the deformation of the crack tip region is incorporated in a continuum mechanical theory. No crack growth criterion is used. The formation of a crack from a surface depr
This note establishes a link between stochastic approximation and extremum seeking of dynamical nonlinear systems. In particular, it is shown that by applying classes of stochastic approximation methods to dynamical systems via periodic sampled-data control, convergence analysis can be performed using standard tools in stochastic approximation. A tuning parameter within this framework is the perio
While several scholars do not consider the anointing of (the feet of) Jesus in Bethany described in the Gospel of John to carry any messianic connotations, some claim that a royal messianic notion is behind the anointing. The hypothesis of this paper is that the anointing is indeed to be understood as messianic, but that it is insufficient to consider only one Christological motif to be in the bac
This paper analyses the internal structure of the terminology of the Enlightenment, actually the process of forming the term “enlightenment” itself within the Indo-European languages and beyond this language family. We use the methodological concept found in the cognitive linguistics on the research of metaphorical extension of lexically meaning of the stem, light, and other morphemes forming the
Sexuality and Socialism is an accessible analysis of many of the most challenging questions for those concerned with full equality for lesbian, gay, bisexual, and transgender (LGBT) people. Sherry Wolf analyzes different theories about oppression - including those of Marxism, postmodernism, identity politics, and queer theory - and challenges myths about genes, gender, and sexuality.
