The paper highlights the data on agroecological assessment and land typing on the example of farm “Kremlin” located in Kochenevo district of Novosibirsk region. This method aims at solving two problems. The first problem deals with typing and it is carried out on the basis of the associated analysis of triunity which implies environmental conditions of the area, agricultural crops, and agricultural technology; the second problem deals with topology: the boundaries of spatial plots of land types coincide with the boundaries of geochemical positions, which are characterized by external features of the relief elements and soil contours. Agroecological land typing includes grouping of lands and their mapping. The criterion for land grouping is seen in similarity of factors that restrict certain crop yields and application of certain technological methods. The authors suggest to use morphometric parameters of the soil mantle for identifying land types: average number of permeable intervals in the section of soil areal, contrast ratio, complexity coefficient and soil cover heterogeneity coefficient. A quantitative parameter of agroecological conditions similarity within the plot is lower contrast ratio. The efficiency of this method is confirmed by economic parameters. Digital mapping and quantitative analysis of morphometric soil mantle parameters was carried out by means of MapInfo Professional software.

Αs technologies and communications develop, more sabotaging attacks occur including phishing attacks which jeopardize users' security and critical information like their passwords and credentials. Several solutions have been proposed for existing dangers. One of which is the use of one-time passwords. This issue has remained as a main challenge and requires more extensive research. In this research, we have focused on one-time password combinations and we also have proposed solutions based on behavioral patterns which lead to significant optimizations while tending the simplicity for users. Efficiency of the proposed method has been measured through defining scenarios, modeling and simulations based on a prevention rate index. In addition, complexity coefficient of the proposed method showing the probability of unpredictability of passwords for attackers has been calculated. Ultimately, a descriptive comparison has shown that the proposed method is superior to some of the existing methods.

Lots of faults exist in rock mass. Acconding on the course of quantitative analysis of fault complexity in mine and modern civil engineering at present, single fault complexity coefficient represents various geologic facts, and its value is less than the fact. Based on the evaluation of sheer incline area ratio and strike-slip fault area ratio about former research, measure fault complexity take an inclined fault interval multiply by the sum of extension length and ratio of numerical statement area. By geometric analysis of geological objects, this paper put forward geometric model which represents geological facts in truth. The results show that expression educed from the model has no multiplicity, is transpicuous and convenient for popularizing.
