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 show the correspondence between the degree of the approximation of the primary curve deakriptivni Taylor series and the degree of the approximation of the support function using Puiseux series. Who is the original author of the concept?

There are examples showing that the multiplicity of the intersection can reskriptivni easily composed out of the intersection multiplicity of the corresponding curve and there are others where it is not so direct. The reason might be difficulties when visualizing various objects with different movements. Predictable shapes reflecting a number of real roots of a univariate polynomial and a possibility to approximate easily the branches separately play a crucial role in the approximation algorithm.

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.

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.


When geometrically analyzing an already built building, it is very difficult to distinguish whether an oval was constructed using circles gometrie ellipses. The gauss map at the inflection point is not regular and in the neighborhood is typically not injective.

Book 1, Science and technologies in geology. A projection plane and two projection directions, not parallel to the plane, are at first assumed.

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 geoemtrie phenomenon. First, we model the famous hyperbolic football manifold, and restrict ourselves only for Cw 6, 6, 6 manifold as in [2].

The support function is thus not regular and typically multivalued. Dualization yields cones which are the envelopes of triples of mutually orthogonal planes. Our main goal is the interpolation of Gk data at the boundaries of ruled surfaces and canal surfaces.

The corresponding conics are the spherical analogues of Thales circles.

An actual problem affected by the precision of positioning geodetic points using new GNSS technologies in coordinate systems is the precision of the map projection. Thank to the addition, basing on the image, deskriptivno will be possible to figure out geometrical features of the photographed object.

But there are many others, too. The method does not enable restitution of the given point basing on its imaging neither application of metrical constructions. The article assessed the quality of general initial training general training and initial training at des,riptivni workplace on-the-job training carried out in selected business entities related to the hard coal mining deskriptibni.


Using the case study, the authors proposed geometfie alternative solution for decision-making problems in mining companies in relation to solutions based solely on unit costs of coal mining. We design a simple algorithm for computing an approximate piecewise rational parametrization using topological graphs of the Weierstrass curves.

Nevertheless, we aim at low degree interpolants, and therefore, we choose the lowest possible n in any case. Marrying these two concepts together with the concept of a symmetric bilinear form, we can make significant progress with regards to the understanding of trigonometry in higher dimensions over a general metrical framework.

Numerical solution of the Kiessl model

A scaling method for priorities in hierarchical structures. User Account Sign in to save searches and organize your favorite content.

Issue 1 First Online: Whereas in the past the study of loci by DGS was based on numerical methods, now we are facing the introduction of symbolic methods based on geoketrie theory of automated theorem proving into DGS.

The standard examples for such theorems are the Theorem of Pythagoras and the Theorem of Desargues concerning perspective triangles. We suggest certain explanations. The case study is preceded by the presentation of general principles regarding cost accounting in mining companies as well as the use of multi-criteria assessments.

We describe this function using an implicit algebraic equation and the rational Puiseux series of its branches. We propose an alternative adaptive subdivision scheme, which ensures the approximation degree 4 both for the inflection—free segments and the segments with inflections.
