Bounding hull, such as convex hull, concave hull, alpha shapes etc. has vast applications in different areas especially in computational geometry. Alpha shape and concave hull are generalizations of convex hull. Unlike the convex hull, they construct non-convex enclosure on a set of points. In this paper, we introduce another generalization of convex hull, named alpha-concave hull, and compare ...

in order to study the effects of four concentrations (check, 5, 10 and 15%) of hull extracts on growth of 10 iranian rice cultivars, two experiments were conducted in completely randomized block design with factorial arrangement and three replications at two sites, laboratory and greenhouse. laboratory study showed that same rice hull extracts had stimulat effects and the others had inhibitory ...

Interest in modular satellites has increased recently. In this paper, we present our approach for planing an OnOrbit-Servicing (OOS) task for a robotic servicer. One key challenge is the gap between the symbolic planing of action sequences and their execution in the continuous space. To bridge this gap, we propose a sampling based workspace description. It is queried by an Hierarchical Task Net...

ships’ magnetic anomalies are one of their main problems encountering sea mines and for the cases of submarines are one of the prominent factors, which causes their fast detection. the main aim of this paper is to design a degaussing system in order to minimize magnetic anomalies of ships. to achieve this goal, first, magnetic signature of a simple ship is simulated. then by utilizing three gro...

Abstract Metal working fluids are used in machining processes of many hard-to-cut materials to increase tool life and productivity. Thereby, the metal act on thermal mechanical loads tool. The changing can mostly be attributed friction between rake face chip changes formation, e.g., contact length chip. However, analyzing those effects is challenging, since a detailed look at formation process ...

The successful manufacturing of glulam from several important Australian commercial timbers is quite challenging due to difficulties in gluing. Improvements adhesive bond performance spotted gum, Darwin stringybark, and southern pine timber have been achieved using alternative pre-gluing surface machining methods, e.g., face milling sanding-post planing, when compared conventional planing metho...

One of the major difficulties introduced with wind power penetration is the inherent uncertainty in production originating from uncertain wind conditions. This uncertainty impacts many different aspects of power system operation, especially the balancing power requirements. For this reason, in power system development planing, it is necessary to evaluate the potential uncertainty in future wind...

In this study the chemical composition and iron bioavailability of hull and hull-less soybean flour from the new cultivar UFVTN 105AP was evaluated. The hemoglobin depletion-repletion method was used in Wistar rats. Soybean hull flour presented 37% more total dietary fiber and higher content of iron than hull-less soybean flour. The phytate:iron molar ratio, however, was 2-fold lower in the soy...
