Evolution Scheme

This paper describes an innovative aerial images segmentation algorithm. The algorithm is based upon the knowledge of image multiscale geometric analysis using contourlet transform, which can extract the image's intrinsic geometrical structure efficiently. The contourlet transform is introduced to represent the most distinguished and the rotation invariant features of the image. A modified Mumford–Shah model is applied to segment the aerial image by a multifeature level set evolution. To avoid possible local minima in the level set evolution, we adjust the weighting coefficients of the multiscale features in different evolution periods, i.e. the global features have bigger weighting coefficients at the beginning stages which roughly define the shape of the contour, then bigger weighting coefficients are assigned to the detailed features for segmenting the precise shape. When the algorithm is applied to segment the aerial images with several classes, satisfied experimental results are achieved by the proposed method.

Hallstatt Period

Starting from some ideas of H. Wolflin, O. Spengler pointed out an interesting problem of correlation between the evolution of art and social evolution. Regardless of the realness of their observations and conclusions, the idea of searching and analyzing such correlations seems to be very fruitful, and especially in the context of preliterate culture surviving due to archeology. This paper, drawing on the empirical archaeological data related to so called Incised and Stamped Pottery Cultures (ISPC) of Early Hallstatt period (XII-IX centuries BC) of Carpathian-Dniester region, aims to consider and verify the ideas of H. Wolflin and O. Spengler. For this purpose, and basing on the previously established by the author fivephase evolution scheme of ISPC of Carpathian-Dniester region (including such a key component of ISPC as Sakharna-Soloncheni culture), the dynamic of fine pottery ornamentation of these societies is analyzed. The analysis demonstrates that the evolution of pottery ornamentation of ISPC started from a minimal number of ornamental patterns and moved towards increasing their number. The parallel tendency was the increasing of the ornamented square of pots. These processes, as well as the innovativeness and openness to external influences, peaked in the fourth phase of Sakharna-Soloncheni culture; this phase was also the time of its greatest prosperity.

Evolution Scheme

The present article describes opportunities for seeking the forms of housing finance, which closely conform to the current needs of the society. The author analyses evolutionary developments of the two main mortgage lending systems, provided either by savings-and-loans banks or by mortgage credit banks. Historical development of loan associations and thrift institutions for housing construction is also in focus of the study. It explores the stages of transferring or, that is also called in literature, “transplantation” of the institutions from the country of origin to other countries. As a consequence of that, the modern studies contain such terms as “donor country” and “recipient country” of the financial institution, which reflect the nature of the transferring (transplantation) process. The evolution scheme of the two main mortgage institutions is considered. Criteria and stages of the institutions’ development in different countries are identified and described in the text. The author also analyses the impact of environment on the institutions’ development, which are dependent on different initial conditions of the institute implementation as well as on social and socio-economic conditions existing in the countries, which choose a certain model of mortgage institutions. The author evaluates the opportunity and attempts to develop the German construction thrift institution model in comparison to classic American mortgage model. The opportunities for developing different forms of mortgage lending in the modern context are under review in the article. They will depend on criteria of difference that financial institutions present as well on conditions of their activity.
