Fouling mechanisms in constant flux crossflow ultrafiltration [PDF]
, 2019 Four fouling models due to Hermia (complete pore blocking, intermediate pore blocking, cake filtration and standard pore blocking), have long been used to describe membrane filtration and fouling in constant transmembrane pressure (ΔP) operation of ...

Generating the Johnson filtration [PDF]
, 2014 For k >= 1, let Torelli_g^1(k) be the k-th term in the Johnson filtration of the mapping class group of a genus g surface with one boundary component. We prove that for all k, there exists some G_k >= 0 such that Torelli_g^1(k) is generated by elements ...

Experimental on liquid passage saturation and pressure drop of gas-liquid coalescing filter material
You-qi chuyun, 2023 The liquid channel characteristics of coalescing filter material directly affect the filtration performance of coalescing filter elements for natural gas purification. Herein, the channel saturation and pressure drop of two kinds of industrial oleophobic

Multiseed Lossless Filtration [PDF]
IEEE/ACM Transactions on Computational Biology and Bioinformatics, 2004 We study a method of seed-based lossless filtration for approximate string matching and related bioinformatics applications. The method is based on a simultaneous use of several spaced seeds rather than a single seed as studied by Burkhardt and K rkk inen [1]. We present algorithms to compute several important parameters of seed families, study their

Finite type invariants of rational homology 3-spheres [PDF]
, 2012 We consider the rational vector space generated by all rational homology spheres up to orientation-preserving homeomorphism, and the filtration defined on this space by Lagrangian-preserving rational homology handlebody replacements.
