A natural generalization of a 2-dimensional angle to higher dimensions is called a solid angle. Given a pointed cone K⊂Rd, the solid angle at its apex is the proportion of space that the cone K occupies. In slightly different words, if we pick a point x∈Rd“at random,” then the...
The solid angle subtended by a circle of radius R with respect to any point is calculated. The solid angle is expressed as a function of the inclination angle θ from the central normal to the circle and the distance λR from the center of the circle. The result is given in terms of ...
(Geom.)a problem requiring in its geometric solution the use of a conic section or higher curve. (Geom.)a problem which can be construed geometrically, only by the intersection of a circle and a conic section or of two conic sections. ...
A range of porosities of the unit cell are obtained by changing the radius of the solid circle or the length of the solid square centered in the cell. Computing and Comparing Effective Properties for Flow and Transport in Computer-Generated Porous Media The school is a concrete building laid ...

The aspect ratio is the ratio of the circumscribed circle over the inscribed circle of the element. EquiAngleSkew equiangle skew = θmax = largest angle of element θmin = smallest angle of element θe = 60º for tetrahedral elements, 90º for hexahedral elements. Displays a mesh ...
The following values are specified for a solid section (geometrical and weighted): Area (Ax). Center of gravity - position in the global coordinate system. Main angles - the angle of inclination of the first main axis in relation to the positive direction of the axis Y of the principal...
a, Angle \(\theta \) between starting and final orientations of a sphere rolled along a target path (same as in Fig. 2a and Fig. 4d) that was deformed non-uniformly in two directions by scaling factors \({k}_{x}\) and \({k}_{y}\) (see Methods for details). Examples of def...
The angle of a full circle is defined via the circumference of a circle with radius r=1: Hence, 360∘=2π rad; accordingly, 1 rad=(180∘/π)≈57.3∘. ... Hence, the solid angle of the full sphere, e.g. the entire sky, is given by 4π sr. ... ...
