Abstract: We formulate the immersed‐boundary method (IBM) as an inverse problem. A control variable is introduced on the boundary of a larger domain that encompasses the target domain. The optimal control is the one that minimizes… read more here.

Abstract: Optimization problem formulation for semi-digital FIR digital-to-analog converter (SDFIR DAC) is investigated in this work. Magnitude and energy metrics with variable coefficient precision are defined for cascaded digital $$\varSigma \varDelta$$ΣΔ modulators, semi-digital FIR filter, and… read more here.

Abstract: Our work starts by offering two statements, given in different historical times and in different epistemic contexts, which reveal two radically different visions of what a problem is and how we should engage with it. read more here.
