The Derivative of Gaussian Transform is a spatial/spatial frequency representation of an image that has been used in image and video compression algorithms. Both the forward and inverse transforms require O(N) operations. In this paper, we consider truncating the length N basis functions to produce a sparse basis matrix and thus to reduce the computational load of the reconstruction. We examine...

The penetration of complexes into the resin domain of the DGT devices has a large influence on the lability degree of these complexes, since the reaction layer (the layer where there is net dissociation) extends from the diffusive gel into the resin domain. Numerical simulation shows that, typically, the contribution to the metal accumulation from dissociation of complexes inside the resin doma...

The European Commission’s (EC) Directorate General for Translation, together with the EC’s Joint Research Centre, is making available a large translation memory (TM; i.e. sentences and their professionally produced translations) covering twenty-two official European Union (EU) languages and their 231 language pairs. Such a resource is typically used by translation professionals in combination w...

In their seminal monograph ’Molecular Theory of Capillarity’, Rowlinson and Widom describe different possible shapes density profiles at the vapor-liquid interface mixtures. They postulated that in some instances, could possibly be non-monotonic, exhibiting either a maximum and/ or minimum. This contribution revisits this statement light four decades posterior research. We summarize distinct mo...

A first test of the field capabilities a novel in situ sampling technique combining active and passive (APS) was conducted sea. The proof-of-concept device uses pump to draw water into diffusion cell where dissolved target substances are accumulated onto sorbents which selective for different classes contaminants (i.e., metal cations, polar non-polar organic compounds), simultaneously. controll...

A general comprehensive picture of kinetic methodologies in soil heavy metal mobilization research area ispresented in this paper. The author‟s experiences and the existing literature have been analysed and discussedbriefly in terms of merits and disadvantages of each kinetic approach in mobilty and bioavailability prediction.The contribution of three kinetic methodologies including...

Land application of biochar, the product organic waste carbonization, can improve soil fertility as well sequester carbon to mitigate climate change. In addition, biochar greatly influence bioavailability toxic trace elements (TTEs) in soils resulting from its large internal surface areas, abundance carbon, and ability modify pH. Most research date employs batch leaching tests predict how addit...
