This work studies the development and application of the multi-objective genetic algorithm based on the Pareto approach, as a tool for the decision making support in the geospatial analysis. Pareto-based evolutionary mechanism developed as an approach to multi-objective geospatial optimisation operates with fixed parameters of genetic operators. It can be used as efficient tool for multi-objective planning both for their power and flexibility and the fact that they generate a whole set of good solutions rather tha...

The subject of the paper is investigation of the properties of concurrent vibro-acoustic signal in the process of rock massif separation with the method of rotary drilling. The aim is to investigate the possibilities of using this signal as an integrating information source for the purposes of identification of the process of separation from the viewpoint of efficiency of the set mode (pressure, revolutions, and indenter) under current geotechnical conditions. Investigated is the possibility of recognition of the ...

In this work, the horizontal failure loads acting in the wall plane and the shear strengths of the walls constructed using solid batch bricks are studied by considering various types of bond arrangements and the results are discussed. For this purpose the samples are produced using simple running bond and polonez bond. In the experimental study is carried out using the procedure proposed in ASTM 1391-81 for the standard shear stress of masonry walls. The observed behavior of the experimental samples and the cracks...

Statement of the problem. In prospecting of deposit, geologists collect many samples, which after chemical analysis of concentration gives a lot of numbers that would be used for resource calculation. Let denote space vector by t (it can be univariate for a hole, bivariate and threedimensional for a deposit), concentration by x(t), and productive part of space by Q. Resource of deposit X composes the integral of concentration x(t) over Q by samples. This is not simple mathematical problem and, consistently, differ...

In this study, behaviors of wall samples produced from solid batch bricks were investigated under horizontal loads using various types of bond. Fort his aim six samples that contain three samples from each one, whose dimensions are 60*60 cm, were prepared. Hatch bond and running bond types were used while preparing the samples. Produced masonry wall samples were failure using experimental technique of standard shear strengths. The observed behavior of the experimental samples and the cracks occurred are studied, h...

The very sharing of resources that lies at the heart of the Grid concepts is of utmost importance in the case that we are studying. Securing the sharing of instruments through industry standard methodologies offers an unprecedented way for scientists to cooperate efficiently through standardized security means, without the incompatibility of implementing interoperability layers for each different experiment and site combination. We performed our model use case analysis in two complementary ways: by the examination...

The offered method is based on consideration of seismic process as a process of Earth’s crust destruction by seismogenetic breaks of different size and location, connected with each other. Special mathematical methods of handling are used to reveal these connections of earthquakes (EQs) that determine place and time of a preparing strong EQ. We’ll divide EQs (1) by their strength in magnitudes, for example 5.0 and 7.0, into weak, moderate, and strong, and (2) by depth, for example 15 and 40 km, into surfacial,...

The web content grows annually by a geometric progression. Internet pages provide information not only through the markup language (X)HTML, which is used to create Web pages, but often in many different other formats and also web services. One task of this project is to make detail analysis of existing web services for obtaining the geographical coordinates of the given information and take advantage of them to extract spatial information from web pages. Positive results of this analysis in Czech information on th...

The contribution deals with the possibilities of unknown part topography defining and with some problems, which originate at the creating of 3D model without drawing documentation details of modelled part. It is concerned to the parts with complex shape. To obtain the dimensions of such undefined real part is often very difficult, especially, if the accuracy requirement is great. The solution of these problems can greatly affect the efficiency of the part manufacturing and so considerably decrease the economic cos...
