The fiber length, chemical composition, and mycototoxins of oat barley hulls were analyzed in order to study the suitability utilize for paper paperboard manufacturing. Oat fibers observed be slightly longer than those (0.80 ± 0.19 mm 0.51 0.17 mm, respectively). There no differences composition hemicellulose sugars, with predominance xylose glucose. amount Klason lignin was at almost same leve...

When a three dimensional object is placed in contact with a supporting plane, gravitational forces move it to one of a nite set of stable poses. For each stable pose, there is a region in the part's connguration space called a capture region; for any initial connguration within the region, the object is guaranteed to converge to that pose. The problem of computing maximal capture regions from a...

Two faba bean (Vicia faba L.) subspecies major and minor and lentil seeds grown in Algeria were separated into cotyledons and hulls. These fractions, together with their corresponding whole seeds, were extracted with two solvents, aqueous (70%) acetone and (80%) ethanol, and evaluated for antioxidant activity in relation to their phenolic contents. Acetone selectively extracted tannins from fab...

We present closed form solutions for the focal length and pose of a camera and two mirrors that are computed directly from the silhouette outlines that appear in a single image. In the noisy case, we show how these equations can be used to form an initial parameter estimate that can be refined with a nonlinear iterative minimisation. This allows five-view visual hulls to be constructed from a s...

Environmental signals are important triggers in the life-cycle transitions and play a crucial role in the life-history evolution. Yet very little is known about the leading ecological factors contributing to the variations of life-history traits in perennial plants. This paper explores both the causes and consequences for the evolution of life-history traits (i.e., seed dormancy and size) in lo...

By the current paper, lift force that is an important characteristic of a planing hull is calculated. To accomplish this task, Morabito’s mathematical model that has been previously derived for prediction of total pressure distribution on planing hulls is utilized. These equations are not restricted to any specific mean wetted length and can be used for planing hulls with large value of mean we...

Selecting a small informative subset from a given dataset, also called column sampling, has drawn much attention in machine learning. For incorporating structured data information into column sampling, research efforts were devoted to the cases where data points are fitted with clusters, simplices, or general convex hulls. This paper aims to study nonconvex hull learning which has rarely been i...

This paper introduces a geometrically inspired large-margin classifier that can be a better alternative to the Support Vector Machines (SVMs) for the classification problems with limited number of training samples. In contrast to the SVM classifier, we approximate classes with affine hulls of their class samples rather than convex hulls. For any pair of classes approximated with affine hulls, w...

Globally non-positively curved, or CAT(0), polyhedral complexes arise in a number of applications, including evolutionary biology and robotics. These spaces have unique shortest paths and are composed of Euclidean polyhedra, yet many properties of convex hulls in Euclidean space fail to transfer over. We give examples of some such properties. For 2-dimensional CAT(0) polyhedral complexes, we gi...
