This paper shows an image/video application using topological invariants for human gait recognition. Using a background subtraction approach, a stack of silhouettes is extracted from a subsequence and glued through their gravity centers, forming a 3D digital image I . From this 3D representation, the border simplicial complex ∂K(I) is obtained. We order the triangles of ∂K(I) obtaining a sequen...

This paper jointly addresses numerical and physical challenges related to the modeling of coalescence filtration through vertical filter cartridges, put forth in following papers by Starnoni, M. C. Manes: • M., & Manes, (2021). A multiphase multicomponent flow transport model for liquid aerosol fibrous filters. Separation Purification Technology, 266, 118574. (2022). On interplay between pressu...

The structure of existing activated models is inherently deficient in reflecting the major role membrane filtration. study developed a novel model, MASM, for process. effective filtration size imposed by module, entrapping larger particles, was adopted as basis proposed model. model defines modified form COD fractionation that accounts captured fractions additional components and utilizes relat...

Seawater pretreatment by gravity-driven membrane (GDM) filtration at 40 mbar has been investigated. In this system, a beneficial biofilm develops on the membrane that helps to stabilize flux. The effects of membrane type, prefiltration and system configuration on stable flux, biofilm layer properties and dissolved carbon removal were studied. The results show that the use of flat sheet PVDF mem...

This concern also applies to filter components and housings. Pall recognizes the importance of proper material selection, cleanliness standards, housing surface preparation, and specialized manufacturing processes with regard to product quality. Our knowledge allowed us to introduce practices that have become industry standards. All Pall Gaskleen filter assemblies are packaged in special double...

BACKGROUND Successful long-term volume retention of an autologous fat graft is problematic. The presence of contaminating cells, tumescent fluid, and free lipid in the graft contributes to disparate outcomes. Better preparation methods for the fat graft before transplantation may significantly improve results. METHODS Subcutaneous fat from 22 donors was divided and processed using various gra...
