Synthesis of Polyvinyltetrazole by Combination of Free Radical Polymerization and Click Chemistry for Adsorption of Pb (II) in Aqueous Solution

Polyvinyltetrazole (PVT) is produced from acrylonitrile (AN) monomer by using free-radicalpolymerization and Click Chemistry methods. The resulting polymer with a broad range of tetrazolegroup contents was conveniently synthesized through [3+ 2] azide-nitrile cycloaddition reaction ofnitrile-containing polymer with sodium azide in DMF. The prepared PVT was characterized by13CN...

Regularization te hniques for the numeri al solution of nonlinear inverse s attering problems in two spa e dimensions are dis ussed. Assuming that the boundary of a s atterer is its most prominent feature, we exploit as model the lass of artoon-like fun tions. Sin e fun tions in this lass are asymptoti ally optimally sparsely approximated by shearlet frames, we onsider shearlets as a means for ...

NCP Function-Based Dual Weighted Residual Error Estimators for Signorini's Problem

In this paper, we onsider goal-oriented adaptive nite element methods for Signorini's problem. The basis is a mixed formulation, whi h is reformulated as nonlinear variational equality using a nonlinear omplementarity (NCP) fun tion. For a general dis retization, we derive error identities with respe t to a possible nonlinear quantity of interest in the displa ement as well as the onta t for es...

Mat hing Numeri Strings under Noise

Abstra t. Numeri string is a sequen e of symbols from an alphabet U, where U is some numeri al universe losed under addition and subtra tion. Given two numeri strings A = a 1 a m and B = b 1 b n and a distan e fun tion d(A;B) that gives the s ore of the best (partial) mat hing of A and B, the transposition invariant distan e is min t2U fd(A + t; B)g, where A + t = (a 1 + t)(a 2 + t) : : : (a m ...
