Hermite interpolation by hypocycloids and epicycloids with rational offsets.

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. Dualization yields cones which are the envelopes of triples of mutually orthogonal planes.

Application of the AHP method allowed to perform a diagnostic comparative assessment of objects business entitiesboth objects and accepted assessment criteria were compared in pairs with each other the evaluator’s preferences subjectivity of assessments are treated in the Analytic Hierarchy Process as a natural phenomenon.

The degrees of the equations admit a prediction of the number of possible solutions. The corresponding conics are the spherical analogues of Thales circles.

We propose an alternative adaptive subdivision scheme, which ensures the approximation degree 4 both for the inflection—free segments and the segments with inflections. Sbornik z 19 seminmare: The concept of choosing an infinite hyperplane is used for making hypothesis in an affine space to solve projective problems and vice-versa.

Starting with geomehrie re-formulation of metrical quantities in n-dimensional affine space using linear algebraic tools, we can deskrjptivni talk about visualising geometric objects in n-dimensional space. The normal or orthogonal quadratic cones have deskriptlvni sections being orthogonal to vertex generators.


Sign in to annotate. But there are many others, too. These parameters are to be determined by solving a system of algebraic equations. Nevertheless, we aim at low degree interpolants, and therefore, we choose the lowest possible n in any case. Springer Spektrum, in preparation. Abstract PDF References Article Recommendations Abstract The paper presents the possibilities of applying one of the multi-criteria assessment methods the development measure method in the processes of multi-variant design of technical and organizational solutions on the example of selecting equipment for a newly designed mine working in a hard coal mine.

In the contribution, we will focus on some interesting constructions used by architects, theorists such as Sebastiano Serlio and Guarino Guarini. De Gruyter – Sciendo. Fundamentals of the analytic hierarchy process. This construction is geomeetrie on a mechanical interpretation of the Apollonius definition an E.

A new viewpoint can give us new ideas and concepts drskriptivni lead to a simplified solution of the mathematical problem. Hence, we deal with rational, elliptic or hyperelliptic curves that are birational to plane curves in the Weierstrass form and thus they are square-root parameterizable. Very often, in technical practice, we meet the concept of oval. The satellite picture of the same object taken geojetrie two different directions may be treated as two-image parallel projection.

Our main goal is the interpolation of Gk data at the boundaries of ruled surfaces and canal surfaces.

Addition of possibility to save the directions of projection broadens way of using the imaging. Equilateral quadratic cones are characterized by a vanishing trace.

And the history of developing this idea is interesting either. Analytic Hierarchy Process, Encyclopedia of Biostatistics. The gauss map at the inflection point is not regular and in the neighborhood is typically not injective. Who is the original author of the concept? These cones can be generated by congruent pencils of planes with intersecting axes. The associated equilateral spherical conics have the property that the three vertices of a regular right-angled spherical triangle can simultaneously move along.


When geometrically analyzing an already built building, it is very difficult to distinguish whether an oval was constructed using circles or ellipses. Journal of Mathematical Psychology, 15, pp.

Therefore, the question arises, what are the conditions which a figure should fulfil to visualise what an author aims at. Kluwer Academic Publishers, pp.

Handbook of convex geometry. We suggest certain explanations. Thank to the addition, basing on the image, it will be possible to figure out geometrical features of the photographed object. The method does not enable restitution of ddeskriptivni given point basing on its imaging neither application of metrical constructions. If cones of this type are tangent to a regular quadric dsekriptivni their apices are located on a sphere.

Based on this results we are able to approximate curve with inflections by curves with a simple support function which consequently possess rational offsets. Problem included in the above trainings were interpreted as a criterion function within a multi-criteria analysis based on the Analytic Hierarchy Process AHP method.

Choice of cartographic projection is determined by the geometrical characteristics of the territory and choice criteria for distortion of map elements. 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.
