Authors want to present the basic concepts of tensigrity structures which are described in the original patents and on the base of this present the realization of tensigrity desskriptivn which were realized in architecture. We show that for a rational surface the Gram determinant of its tangent space is a perfect square if and only if the Gram determinant of its normal space is a perfect square. The given method is based on imaging of Euclidean space on feometrie plane.

Addition of possibility to save the directions of projection broadens way of using the imaging. When geometrically analyzing an already built building, it is very difficult to distinguish whether an oval was constructed using circles or ellipses. Our main goal is the interpolation of Gk data at the boundaries of ruled surfaces and canal surfaces.

The impact of the flow volume flow ventilation to the location of the special hazard spontaneous fire zone in goaf with caving of operating longwalls.

We use the presented approach to interpolate a network of points and associated normals with piecewise polynomial surfaces with polynomial area element. Nevertheless, we aim at low degree interpolants, and therefore, we choose the lowest possible n in any case. We design a simple algorithm for computing an approximate piecewise rational parametrization using topological graphs of the Weierstrass curves.

Nowadays new groups of scientists are looking for the best and precisly definition for tensigrity and they are trying to defined true or false tensigrity structures. Analytic Hierarchy Process, Encyclopedia of Biostatistics. The first tensegrity structure was constructed in by Kenneth Snelson, the young student of art. Therefore, the question arises, what are the conditions which a figure should fulfil to visualise what an author aims at.

Map projections are coming out of geometric expression of properties of reference surfaces of Earth using methods of differential geometry, as well as of relation between two linear manifolds – reference ellipsoid and map plane. Curves and surfaces represented by polynomial support functions. We propose an alternative adaptive subdivision scheme, which ensures the approximation degree 4 both for the inflection—free segments and the segments with inflections.

The aim of this paper is to show the role of geometry and mathematics in the cartography and different options for access to the distortions of the territory, such as optimization of extreme value of distortion, summing and integral criterion on area territory, in some case using criterion with the requirement of a minimum mean value of scale distortion in a given area. A new viewpoint can give us new ideas and concepts that lead to a simplified solution of the mathematical problem.

The method does not enable restitution of the given point basing on its imaging neither application of metrical constructions. We show the correspondence between the degree of the approximation of the primary curve using Taylor deskrptivn and the degree of the approximation of the support function using Puiseux series.

Bolek have submitted a new projection method. Very often, in technical practice, we meet the concept of oval. First, we model the famous hyperbolic football manifold, and restrict ourselves only for Cw 6, 6, 6 manifold as in [2].

Thank to the addition, basing on the image, it will be possible to figure out geometrical features of the photographed object.

Together with geometric criteria, useful solutions, i. Sign in to annotate. Choice of cartographic projection is determined by the geometrical characteristics of the territory and choice criteria for distortion of map elements. Determination of the zone endangered by methane explosion in goaf with caving of operating longwalls.

All the time the idea dexkriptivn tensigrity structure is focusing attention of scientists connected with architecture. Hermite interpolation by hypocycloids and epicycloids with rational offsets.

In the contribution, we will focus on some interesting constructions used by architects, theorists such as Sebastiano Serlio and Guarino Guarini. The quality of approximate constructions may be the reason. The technique we use applies to both types of surfaces, because they can be represented as curves within the afore mentioned quadrics. The reason might be difficulties when visualizing geometgie objects with different movements. A scaling method for priorities in hierarchical structures.

The Universe of Quadrics. Based on this results we are able to approximate curve with inflections by curves with a simple support function which consequently possess rational offsets.
