The paper is concerned to the synthesis of synchronous generator’s regulatory control algorithm that is one of the main elements of power system and power stations, in a whole. The algorithm allows to improve the stability margin of synchronous generator’s control system. Because of integrated derivatives’ observer synthesized algorithm allows to detect the lever of unwanted disturbance in the process of electric power’s generation and adjust the work of generator. It is conducted the modeling that shows high resistance of spectator, quality of transients and steady mode of synchronous generator’s model status variables. The quality of free-form signal spectator’s assessment  is generated with enough high degree of accuracy that raises with the improvement of operation speed’s features of observer and regulator.

The represented approach of dynamic process modeling is based on the technology of automatical semantic text analysis. An associative network is forming during text processing. Its key notions, including  lexical and psycholinguistic markers of the analyzed process, are ranked by theirs semantic weight. The weight being multiplied by marker status value at the scale of “good-bad” gives its contribution to the process stage characteristic. Transformation of the accumulated for all of the markers process characteristic from one period of time to another one is characterize a direction of the process.

Case is an event that took place in the past and can be an example for similar steps in present. Case-based reasoning (CBR) is a methodology of finding a decision based on previous experience. The main difficulties in CBR are recognition of present situation of decision-making and finding similar case in the past. Making a decision in the field of purchasing drugs is a quite difficult and many-valued task with a plenty of various parameters, which however might be solved with the help of CBR. CBR is an important and perspective area of artificial intelligence (AI) decision support systems. Constantly growing research amount has already led to breakthroughs in theoretical part of AI and in AI-based applications. The general case model and formula for determining cases similarity is suggested in this work. Application of the formula will help determine similarity of cases and make the better decision.

The article is devoted to the problem of the identification of the Black Sea – Caspian region as a special segment of the World Space in the postbypolar system. The Great Limitrophe conception developed by V.L. Tsymbursky and S.V. Khatuntsev is used as «the structural frame» for understanding modern peculiarities of this region. The author outlines two aspects of its identification: geopolitical and geocivilozational. He also introduces the key concept «limitroph territory» adapting it to the specific region. The key concept involves two other concepts – «shatterbelt» and «(inter)civilizational split zone». The article contains brand new facts on the Black Sea – Caspian region problem.
