inclined retaining walls with slopes less than perpendicular are appropriate candidates in several engineering problems. yet, to the knowledge of authors, only a few analytical solution for calculation of active earth pressure on such walls, which will be usually smaller than the same pressure on vertical ones, has been presented neither in research papers nor in design codes. considering limit...

We use passive and active techniques to study microrheology of a biopolymer solution. The passive technique is video tracking of tracer particles in the biopolymer, a technique which is well established. The active technique is based on rotating optical tweezers, which is used to study viscosity. A method to actively measure viscoelascity using time varying rotation of a particle trapped in opt...

vessel extraction is a critical task in clinical practice. in this paper, we propose a new approach for vessel extraction using an active contour model by defining a novel vesselness‑based term, based on accurate analysis of the vessel structure in the image. to achieve the novel term, a simple and fast directional filter bank is proposed, which does not employ down sampling and resampling used...

In this chapter we consider optimal control problems with additional inequality constraints imposed on the control unknown u and for their efficient solution we combine a primal-dual active-set strategy with the multigrid method developed in the previous chapter. Control-constraints are specified by the condition u ∈ Uad, where the set of admissible controls Uad ⊂ L(Ω) is a proper subset of L(Ω...

The deep active-subspace method is a neural-network based tool for the propagation of uncertainty through computational models with high-dimensional input spaces. Unlike original method, it does not require access to gradient model. It relies on an orthogonal projection matrix constructed Gram–Schmidt orthogonalization reduce dimensionality. This incorporated into neural network as weight first...
