EFFECTS OF FIELD’S TOPOLOGY ON ENERGETIC EFFICIENCY OF RAPESEED PLANTATION FOR BIOFUEL PRODUCTION

The model, developed earlier, have been designed to the studies of energy gain in the  biofuels production, as compared to the  sum of energy inputs on various production steps, and in processes enabling biomass conversion to energy. The present paper shows application of that model towards estimation of the contribution of energy used for commuting between agricultural production sites for a chosen example of plantation’s topological characteristics.  Algorithm for computations is elaborated, and numerical example is shown. The sizes of the fields as well as distances between them determine the amount of energy spend for the agricultural work in addition to the tillage technologies being applied.

THE ANALYSIS OF THE IMPACT OF THE REGULATORY COMPONENT ON BUSINESS ENVIRONMENT IN UKRAINE

To analyze the impact of the normative regulatory sphere on business environment in Ukraine in order to identify shortcomings of the existing mechanism of the regulatory activities and prospects of its improvement on the current stage of economic development. To prove the feasibility of studies towards the formation mechanism of information relations in the regulatory activity.

THE ACCURACY OF AN ACCELERATED METHOD FOR THE EVALUATION OF LIFE OF CYLINDRICAL GEARS WITH PROFILE CORRECTION

This paper presents an accelerated method for the evaluation of life of cylindrical gears with profile correction. Compared to a more accurate solution based on the generalized method for evaluating the wear and life of cylindrical involute gears, the new method enables accelerating this process by over 16000 times. The method was used to estimate the life of a cylindrical spur gear depending on different ranges of blocks describing gear teeth meshing conditions (i.e. the number of gear revolutions). The accuracy of the results obtained thereby was examined, too. It has been found that when the range of a block is increased by 3000 times, the deviations of the numerical solution are below 0.5%.

SELECTED METHODS OF MAKING THREE-DIMENSIONAL VIRTUAL MODELS OF MUSEUM CERAMIC OBJECTS

The paper presents available three-dimensional scanning technologies with a particular focus on the digitisation process of ceramic objects. of the research carried out show that in digitising ceramic objects with concave ornamentation by the Roland PICZA LPX-600 scanner the method of scanning by planes should be used. While digitising such objects with the ZScanner ® 700 one should use the resolution of 0,4 mm. The paper also shows the suitability of reference imaging in recreating the shape of the object in constructing 3D models. This shape can be used in virtual assembly of the shells of broken ceramic vessels.

DESIGNING OF STRUCTURAL ONTOLOGICAL DATA SYSTEMS MODEL FOR MASH-UP INTEGRATION PROCESS

This paper describes the construction of structural ontological data systems model in the process of data integration. The usage of ontologies in the context of improving the process of dynamic semantic data integration has been characterized. The algorithm of constructing of structural ontological data integrated systems model has been designed. This algorithm is based on the rules of using and application of ontological modeling. The algorithm as a sequence of five steps describing tasks for each of them has been presented.
