The submarine is usually affected by free surface and the navigation resistance increases when sailing near surface. In order to study specific characteristics of surface, SUBOFF with appendages was taken as research object, calculation model built based on Star CCM+ fluid simulation software, coefficients under different depths speeds were calculated. Through comparative analysis, influence de...

Nowadays, the floating production storage and offload system (FPSO) is one of most common platform types for offshore oil production. The traditional arrangement stiffened panels creates obstacles automated cleaning inspections by remote devices. This paper summarizes results an initial study design construction FPSO hulls with SPS in order to overcome this problem. main goal have walls bottom ...

BACKGROUND A large body of evidence suggests that antipsychotic drugs cause body weight gain and type 2 diabetes mellitus, and atypical (new generation) drugs appear to be most harmful. The aim of this study was to determine the effect of short-term olanzapine (atypical antipsychotic drug) and haloperidol (conventional antipsychotic drug) treatment on glucose and lipid metabolism. RESEARCH DE...

We provide an explicit description of the convex hull of the set of matrices of bounded rank, restricted to balls for the spectral norm. As applications, we deduce two relaxed forms of the rank function restricted to balls for the spectral norm: one is the quasiconvex hull of this rank function, another one is the convex hull of the rank function, thus retrieving Fazel's theorem (2002). Key-wor...

We study the complexity of computing the mixed-integer hull conv(P ∩ Z ×R) of a polyhedron P . Given an inequality description, with one integer variable, the mixed-integer hull can have exponentially many vertices and facets in d. For n, d fixed, we give an algorithm to find the mixed integer hull in polynomial time. Given P = conv(V ) and n fixed, we compute a vertex description of the mixed-...

THE postfertilization development of the ovary of the hazel flower results in the formation from the outer integument of the ovule of a thin fibrous seed coat closely adherent to the embryo and from the ovary wall of a hard, lignified pericarp which is quite free from the seed coat at the time when the fruit is ripe. The work recorded in this paper was done on the pericarp of the hazel fruit. T...

We present efficient algorithms to construct both C1 and C 2 smooth meshes of cubic and quintic A-patches to approximate a given polyhedron P in three dimensions. The A~patch is a smooth and single-sheeted zero-contour patch of a trivariate polynomial in Bernstein-Bezier (BB) form defined within a tetrahedron. The smooth mesh constructions rely on a novel scheme to build an inner simplicial hul...

abstract: this study was conducted to investigate the effects of diets containing different levels of hull-less barley on caecal microflora of broiler chicks. two hundred and forty one-day old male broiler chicks (arbor acres strain) were used in a completely randomized design with 4 tratments, and 3 replicates were allocated to each treatment. different levels of hull-less barley in diets had ...

This article gives an overview of the concept of the Visual Hull and what its advantages and disadvantages are. The Visual hull is a concept of a 3D reconstruction by a Shape-From-Silhouette (SFS) technique. This kind of 3D scene reconstruction first has been introduced by Baumgart in his PhD thesis in 1974 [1]. Since then there have been several different variations of the Shape-From-Silhouett...
