Abstract A robust segmentation method that can be used to perform measurements on toenails is presented. The proposed as the first step in a clinical trial objectively quantify incidence of particular pathology. For such an assessment, it necessary distinguish nail, which locally appears similar skin. Many algorithms have been used, each leverages different aspects toenail appearance. We Hough ...

Background: Radon and its daughters are amongst the most important sources of natural exposure in the world. Soil is one of the significant sources of radon/thoron due to both radium and thorium so that the emanated thoron from it may cause increased uncertainties in radon measurements. Recently, a diffusion chamber has been designed and optimized for passive discriminative measurements of rado...

Construction of cable supported bridges has experienced a great impulse in the past decade. Bridges having more than 800 m of span length were built in France and Japan and some bridges with span length of more than 1 km are going to be built, such as the Stonecuters bridge in Hong-Kong, and the Chongming in China (Fig. 1). Because of the increasing length of this class of bridges, they are bec...

Nearly all the neutral iridium complexes widely used as dopants in PhOLEDs are racemic mixtures; however, this study observed that these complexes can be separated into stable optically active Λ and ∆ isomers and that their chirality is an intrinsic property. The circularly polarised phosphorescent photoluminescence (CPPPL) signals of Λ/Δ isomers are perfect mirror images with opposite polarisa...

Most aeolian sediment transport models and experiments have been conducted on flat horizontal surfaces. Very little numerical or analytical research has been carried out for aeolian sand transport on slopes. The current work presents numerical modelling of saltating sand for a climbing dune which has a slope angle of 20”. The model utilised wind fields predicted from the FAA complex terrain mod...

For more than thirty years, rnvestrgators have recognized that luminescence measurements made with certam experimental geometries require corrections for the refractive index of the solution [I,?]. These corrections are necessary when the ratio of luminescence from two solutrons IS required, as in relatrve quantum yield measurements [3]. In many cases, the m~gnttude of these corrections is not ...
