A model of motion detection is presented. The model contains three stages. The first stage is unoriented and is selective for contrast polarities. The next two stages work in parallel. A phase insensitive stage pools across different contrast polarities through a spatiotemporal filter and thus can detect first and second order motion. A phase sensitive stage keeps contrast polarities separate, ...

ginger waste material (gwm) has been utilized as adsorbent for removal of hazardouspatent blue vf (pbvf) dye from aqueous solution. batch adsorption experiments wereperformed as a function of ph, contact time, dye concentration, adsorbent dose and temperature.the optimum ph required for the maximum adsorption was found to be 2. the experimentalequilibrium adsorption data were tested using langm...

In this paper we find the first and second order perturbations of the induced metric and the extrinsic curvature of a non-degenerate hypersurface Σ in a spacetime (M, g), when the metric g is perturbed arbitrarily to second order and the hypersurface itself is allowed to change perturbatively (i.e. to move within spacetime) also to second order. The results are fully general and hold in arbitra...

In this paper we investigate strong logics of first and second order that have certain absoluteness properties. We begin with an investigation of first order logic and the strong logics ω-logic and β-logic, isolating two facets of absoluteness, namely, generic invariance and faithfulness. It turns out that absoluteness is relative in the sense that stronger background assumptions secure greater...

3 Production of lemmas in first order logic 10 The method "Model Elimination is a proof method very easy to implement and it is the reason of his success. To present it, we use the following references [OD97], [Don78] et [Sut12]. The last document presents clearly and concisely the production of the lemma. Without this help, it would have been impossible to write this explanation of the method ...
