FORECASTING GDP GROWTH RATE IN UKRAINE WITH ALTERNATIVE MODELS

The problem of constructing mathematical model for short-term forecasting of GDP is considered. First, extended autoregression is constructed that takes two additional independent variables into  consideration. The model resulted provides a possibility for generating short-term forecasts of GDP though not of high quality. Another model was constructed in the form of a Bayesian network. The model turned out to be better than the multiple regression, it provides quite good estimates for probabilities of GDP growth direction.

INTERACTIVE METHODOLOGY FOR SPATIAL REPLICATION AND RESEARCH

The paper outlines geographic search technology as the future of research methodology. Due to the importance of geographical environment in the routine issues, the close connection between spatial extension and most of the phenomena running over the world, the geographic query process turns to be key factor in overcoming hazard decision-making and evaluation. We describe a two step process where derived output from spatio-textual research could be largely disseminated by spatial replication techniques. Spatial research differs in that it requires a combination of text and geographical data. The mathematical formula to calculate distances derives from the assertion that the Earth is nearly spherical (ignoring ellipsoidal effects) so great-circle distance formulas give the distance between points on the surface of the Earth correct to within 0.5% or so. Based on the search range and limit, we introduce the Cosine algorithm who offers better speed performance and data retrieval accuracy. Retrieved data exploit spatial replication technique potentiality. When it comes to spatial data we deal extensive amount of information. Web Gis Albania is an informative platform initially structured for academicals purposes further enriched with modules which support the spatial data circulation.

MODELLING OF UAV'S COMPOSITE STRUCTURES AND PREDICTION OF SAFETY FACTOR

The paper presents possibilities of composite materials modeling using SolidWorks enviroment on example of Unmanned Aerial Vehicle wing structure. Mechanical properties of composite materials used in UAV's and process of modeling such structures in SolidWorks are described. The research problem is CFD and strenght analysis of considered structure in SolidWorks Flow Simulation. Different displacement, stresses and safety factors values were obtained for analysed types of loads. The presented approach was used to develop aircraft wing for Air Challenge 2015 competition.

THE METHOD FOR DETECTING PLAGIARISM IN A COLLECTION OF DOCUMENTS

The development of the intelligent system for searching for plagiarism by combining two algorithms of searching fuzzy duplicate is considered in this article. This combining contributed to the high computational efficiency. Another advantage of the algorithm is its high efficiency when small-sized documents are compared. The practical use of the algorithm makes it possible to improve the quality of the detection of plagiarism. Also, this algorithm can be used in different systems text search.

THE MODEL AND FUNCTION OF QUALITY ASSESSMENT OF IMPLEMENTATION OF DESIGN PATTERNS

One of the ways of providing high internal software quality (that is a source code) is using design patterns. The article aims at presenting a suggested model which enables one to assess the quality of implementation of design patterns. The model assumes verification of different aspects of the patterns and a numeric expression of the obtained results. The analysis of the obtained results may show the occurrence of certain problems which are difficult to be identified during code review or testing.
