EFFECTS OF TILLAGE TECHNOLOGY ON ENERGETIC EFFICIENCY OF RAPESEED PLANTATION FOR BIOFUEL PRODUCTION

Biofuel production, as well as any other production processes, involves a number of conversion steps each of those is connected with unavoidable consumption of energy. Since biofuels are intended to replace fossil fuels it is important that the sum of energy inputs into subsequent technological steps does not exceed the energy output from the system. Basing on theoretical model derived recently by present authors, energy requirements for several agricultural technologies are computed, and used for estimation of energetic efficiency of rapeseed plantations dedicated for biodiesel fuel production. The effects of technological choices on energetic efficiency of plantations are demonstrated basing on numerical compu-tations performed using realistic data.

THE SYSTEM DEVELOPING OF FORMING RESEARCH SCHOOLS BASIS OF PUBLICATION ELEMENTS ANALYSIS

In this paper the method of research publications elements analysis that is determining common qualities of research publications and their clustering as an instrument of selecting and sorting out the information about research schools has been introduced. In module structuring documents transmitted there are tape that indicates the address of the file. Depending on where the file is, it can be a path to a file on the local disk or URL on the Internet.

IMPLEMENTATION OF MS ACCESS SOFTWARE FOR CASING-CLASS MANUFACTURING FEATURES SAVING

Manufacturing features are widely accepted as a means for the CAD, CAPP and CAM systems and their integration. Despite high number of works in this area, the investigations on the methods on manufacturing features saving are still limited and many results are not suitable for manufacturing systems design purposes. The paper presents possibility of using the MS Access software for saving and management of constructional data of casing-class parts. Therefore, the method of representation and saving casing- lass constructional knowledge was developed. The proposed method is based on application of the design feature technique.

INTERACTIVE CALCULATOR FOR ASSESSMENT OF THE STRUCTURE OF ENERGY CONSUMPTION

In this paper we present a simple interactive calculator, which can be used in individual flats and houses, office buildings and educational institutes such as colleges and schools, for assessment of electricity use by different categories of equipment. The user indicates only type of equipment and its approximate time of work. The program outputs the structure of energy consumption in graphic format. The results of test procedures and the ways for improvement of the program are discussed.

APPLICATION OF ADDITIVE TECHNOLOGY OF FUSED DEPOSITION MODELING FOR MANUFACTURING SMALL SERIES OF ELASTIC MODELS

The paper presents an application of additive method of Fused Deposition Modeling for manufacturing of small series of elastic models. Additive FDM technology is used to produce a casting mould for multiple use. Process of manufacturing of small series of products consists in casting a two-component silicone rubber degassed using vacuum chamber into a multiple use mould. The paper shows the course of the process and related problems on the example of industrial product – a cylindrical seal. The casting mould was produced out of ABS material using BST 1200 machine, whereas casted elastic models were made out of XTX 45 silicone rubber.

FEATURES OF INFORMATION RESOURCES PROCESSING IN ELECTRONIC CONTENT COMMERCE

Some solutions of main problems of content e-commerce and content management services are described in the paper. Content lifecycle model in electronic commerce systems is considered. The model gives an opportunity to create effective tolls of information resources processing in electronic commerce systems and to implement the subsystem of commercial content formation, management and support.
