As a result of this theory, in the case of a retaining wall supporting a vertical face of earth beneath an extended horizontal plane level with the top of the wall, we get p _ wx 2 1 - sin ii 2 I +sin P' [[Reservoir Empty Reservoir Full Ellipses Of Vertical Pressures On Horizontal Joints]].
Fish farms are represented by the filled rectangular block, with the areas of impacted seabed denoted by the filled ellipses.
Hence the locus of J relative to AB, and the locus relative to CD are equal ellipses of which A, B and C, D are respectively the foci.
If the whole globe were covered with a uniformly deep ocean, and if there were no difference of density between one part and another, the surface would form a perfect ellipsoid of revolution, that is to say, all the meridians would be exactly equal ellipses and all parallels perfect circles.
Most of the orbits are remarkably eccentric ellipses, the average eccentricity being about 0.5.
The number of irregular ellipses or circles made within a given time differs much with different species.
These store the image as a set of graphic primitives; shapes such as lines, ellipses, rectangles and polygons.
Three test points are shown with their uncertainty ellipses.
We receive, therefore, in no single intercepting plane behind the system, as, for example, a focussing screen, an image of the object point; on the other hand, in each of two planes lines 0' and 0" are separately formed (in neighbouring planes ellipses are formed), and in a plane between 0' and 0" a circle of least confusion.
