Udder capacity and udder shape were scored on 3- to 10-yr-old cows from a large Hereford herd. Udder capacity was scored from 1 (small) and 5 (large) and udder shape was scored from 1 (balanced, udder level with ground) to 5 (unbalanced, funnel-shaped udder). Data were analyzed within age of cow for udder capacity scores from 1 to 4 and for udder shape scores from 1 to 3 because of the limited ...

The data acquisition from the shape of an object is a must to complete its quantitative displacement measurement analysis. Over the past years whole field of view optical non-invasive testing has been widely used in many areas, from industrial ones to, for instance, biomedical research topics. To measure the surface contour from the tympanic membrane (TM) of ex-vivo cats digital holographic int...

In OBASC based on the source model ”moving textured rigid 3D objects with non–diffuse illumination” the shape of model objects describing real objects is estimated from the silhouettes of the real objects assuming an ellipsoid–like shape. In this paper, the image analysis is extended by a global shape estimation method evaluating directly the image signal. By one global shape parameter, the dep...

The maximum power cast on a collector from a source of finite angular extension by a concentrator of fixed position occurs when the collector sees the concentrator as a Lambertian source. Concentrators not fully meeting this requirement are evaluated using a parameter called the shape quality factor. Lambertian concentrators can be obtained with mirrors but not with lenses of finite n. In many ...

Source based heterogeneous modelling is a powerful way of defining gradient materials within a volume. The current solutions do not take into account the topology of the object and can provide counter intuitive results for complex objects. This paper presents a method to interpolate material properties and attributes based on the accessibility of the points in respect to the material features d...

We describe the principles of design and the architecture of planar microfluidic networks producing concentration gradients with the shape of any given monotonic function. Each microfluidic network is fed by two separate source solutions and delivers to its outlet a set of N solutions that all differ in concentration. Inside the network, the source solutions flow through a series of k = log(2)(...

Abstract In this article a novel algorithm is presented for 2-D shape interpolation using the intrinsic shape parameters of a piecewise linear curve. The skeletons of two given shapes are computed and the smooth transformation of distance fields is driven by metamorphosis from the skeleton of the source object to that of the target one. We introduce feature graphs, linear forms of skeletons, to...

For over thirty years researchers have been trying to solve the shape from shading problem of determining 3D shape from a single image with a single light source. The basic problem of determining shape from shading is made more difficult due to challenges of light orientation, camera type, ambiguity, multiple materials, and specular highlights. This paper shows how some of these challenges can ...

Aktruct-Uncertainty concerning sensor locations can seriously degrade the ability of an array to estimate the location of radiating sources. Array calibration then becomes an important issue. This paper deals with array calibration using spectrally disjoint near-field sources whose locations are not known a priori. .It calculates CramerRao bounds on source location and array shape errors. It sh...

Image gradients--smooth changes in color and luminance--may be caused by intrinsic surface reflectance properties or extrinsic illumination phenomena, including shading, shadowing, and inter-reflections. In turn, image gradients may provide the visual system with information concerning the origin of these factors, such as the orientation of surfaces with respect to the light source. Color gradi...
