This paper is concerned with the problem of computing a discrete-coefficient approximation to a digital filter. In contrast to earlier works that have approached this problem using standard combinatorial optimization tools, we take a geometric approach. We define a Riemannian manifold, arising from the difference in frequency response between the two(More)
1 The availability of low-cost multi-core systems enables LabVIEW to combine sophisticated data acquisition systems with demanding numerical tasks. In a typical scenario information about a system is based on direct or derived measurements and the acquired data is used to solve linear or even nonlinear elliptic partial differential equations. The results(More)

Solvent extraction is recommended as a suitable method for the removal of heavy metals from the waste waters of the chemical and electronic industries. Common extractants are organic compounds with molecular mass 200-450, almost insoluble in water (5-50 ppm), that selectively extract metals from aqueous solutions. On the basis of data from the literature,(More)
