this research studied the addition of hull-less barley and wheat malt flour on the qualitative parameters of semi-voluminous bread (form, softness, porosity, upper and under surface characters, chewing capability, aroma, taste, hardness). a completely randomized design was used with 3 treatments (control, use of malted wheat, use of barley flour) in 4 replications. a sensory evaluation and the ...

The convex hull describes the extent or shape of a set of data and is used ubiquitously in computational geometry. Common algorithms to construct the convex hull on a finite set of n points (x,y) range from O(nlogn) time to O(n) time. However, it is often the case that a heuristic procedure is applied to reduce the original set of n points to a set of s < n points which contains the hull and so...

We propose a hull operator, the reflex-free hull, that allows us to define a 3D analogue to bays in polygons. The reflex-free hull allows a rich set of topological types, yet for polyhedral input with n edges, it remains a polyhedral set with O(n) edges. This is in contrast to other possible hull definitions that give non-planar surfaces and higher combinatorial complexity. The reflex-free hull...

Stern wave flow phenomena are investigated in a full-scale Kriso container ship. The hull roughness effects studied with and without propulsion. Reynolds-averaged Navier–Stokes (RANS) detached eddy simulations (DES) utilized the ghost-fluid method (GFM). DES is carried out submodel where stationary RANS solution used as boundary condition. surface effect on stern significant due to increased la...

A multidisciplinary design optimization scheme for ships has been developed for use in an integrated ship design environment. Although the system was designed with the intention of using analysis techniques based on first principles, the containership design examples presented in this paper make use of parametric analysis modules developed to examine problem formulation issues prior to the avai...

This report focuses on the acquisition of shape and appearance of real objects under static illumination without the need for an elaborate calibration process or an expensive setup. Emphasis is placed on ease of use and obtaining visually pleasing results. Using recent advances in matting techniques, an opacity hull of the object is computed from an un-calibrated sequence of photographs. User i...

The visual hull is widely used as a proxy for novel view synthesis in computer vision. This paper introduces the safe hull, the first visual hull reconstruction technique to produce a surface containing only foreground parts. A theoretical basis underlies this novel approach which, unlike any previous work, can also identify phantom volumes attached to real objects. Using an image-based method,...

In order to design a patient-specific simulator of pelvic organs, MoDyPe project considers the organs as thick surfaces. Starting from a closed parametric surface for the outer hull, an offset approach is applied. However, respecting the thickness on the surface and ensuring the absence of self-intersection is impossible if the shape has too important local curvatures. Two iterative approaches ...
