Rice hull, the outer cover of the rice grain, determines grain shape and size. Changes in the rice hull proteome in different growth stages may reflect the underlying mechanisms involved in grain development. To better understand these changes, isobaric tags for relative and absolute quantitative (iTRAQ) MS/MS was used to detect statistically significant changes in the rice hull proteome in the...

This paper supposes a schema to deal with the tough task of building detection and recognition from high resolution remotely sensed imagery. It is a region-based and semi-automatic schema combining with Hough transform and computation of convex hull of the pixels contained in the building areas, which can produce a precise result when the contrast between flat building rooftop and the backgroun...

Many applications in computer vision require the 3D reconstruction of a shape from its different views. When the available information in the images is just a binary mask segmenting the object, the problem is called shape from silhouette (SfS). As first proposed by Baumgart [1], the shape is usually computed as the maximum volume consistent with the given set of silhouettes. This is called visu...

Alpha shapes are well known geometric objects which generalize the idea of a convex hull, and provide a good definition for the shape of a given point set V . For a given point set V in 2 or 3 dimensions, we show that the knowledge of pairwise distances between pairs of points which are closer than a certain distance is sufficient to compute the alpha shape. We also show that the alpha shapes c...

Most of previous papers in the field of dye removal used one dye or dyes with nearly separate spectra that simplifies dyes concentration determination by Beer's law at different λmax. In many real situations, dyes with highly overlapped spectra exist and their concentrations can be determined by multivariate analysis methods. In this study, principal component-wavelet neural network (PC-WNN) wa...
