Colour analysis of inhomogeneous stains on textile using flatbed scanning and image analysis
This paper describes a method for the determination of the colour of inhomogeneous stains on textile using flatbed scanning (FBS) and image analysis (IA). The method can be used to assess the cleaning performance of laundry detergent products. Stains on textile were visualised using a standard flatbed scanner. A fully automatic procedure was developed using image analysis (IA) software. Differe...
متن کاملStains on the carpet.
One summer evening in 2004 our 11 year old son went to bed after various delaying tactics—arguments about friends who stay up later, forgetting to brush teeth, coming down for a drink of water. Shortly afterwards the dining room door opened. In he came, cupping his bleeding nose in one hand as he gripped the bridge of the nose with the other. We led him to the kitchen sink to help him clean up ...
متن کاملEvaluation of homogenized thermal conductivities of imperfect carbon-carbon textile composites using the Mori-Tanaka method
Three-scale homogenization procedure is proposed in this paper to provide estimates of the effective thermal conductivities of porous carbon-carbon textile composites. On each scale the level of fiber tow (micro-scale), the level of yarns (meso-scale) and the level of laminate (macro-scale) a two step homogenization procedure based on the Mori-Tanaka averaging scheme is adopted. This involves e...
متن کاملTreatment Options for Oil Stains on Paper
Oil stains on paper can be disfiguring and resistant to treatment. This study compares treatments involving solvents, enzymes, surfactants, and bleaches that paper conservators have reported to be successful. Nine immersion treatments and sixteen local treatments were chosen for evaluation. Three questions were posed at the beginning of the study: (1) Which solutions or solvents are the safest ...
متن کاملElectron Stains
Chemical studies have been carried out on the interaction of DNA with uranyl salts. The effect of variations in pH, salt concentration, and structural integrity of the DNA on the stoichiometry of the salt-substrate complex have been investigated. At pH 3.5 DNA interacts with uranyl ions in low concentration yielding a substrate metal ion complex with a UO(2) (++)/P mole ratio of about (1/2) and...
