The subject of consideration is the task of identifying the states of an object based on the results of fuzzy measurements of a set of controlled parameters. The fuzziness of the initial data of the task further complicates it due to the resulting inequality of the controlled parameters. The aim of the study is to develop a method of identifying the states of a fuzzy object using a fuzzy mechanism of logical output taking into account possible differences in the level of information content of its controlled parameters. The method of obtaining the desired result is based on the modification of the known mathematical apparatus for building an expert system of artificial intelligence by solving two subtasks. The first is the development of a method for assessing the informativity of controlled parameters. The second is the development of a method for constructing a mechanism for logical inference of the relative state of an object based on the results of measuring controlled parameters, which provides identification. In the first problem, a method is proposed for estimating the informativity of parameters, free from the known disadvantages of the traditional Kulbak informativity measure. In implementing the method, it is assumed that the range of possible values for each parameter is divided into subbands in accordance with possible states of the object. For each of these states, the function of belonging to the fuzzy values  of the corresponding parameter is defined. At the same time, the correct problem of estimating the informativity of a parameter is solved for cases when this parameter is measured accurately or determined fuzzily by its belonging function. The fundamental difference between the proposed logical output mechanism and the traditional one is the refusal to use the production rule base, which ensures the practical independence of the computational procedure from the dimension of the task. To solve the main problem of identifying states, a non-productive approach is proposed, the computational complexity of which practically does not depend on the dimension of the problem (the product of the number of possible states Results.per the number of controlled parameters). The logic output mechanism generates a probability distribution of the system states. In this case, a set of functions of belonging of each parameter to the range of its possible values for each of the states of the object is used, as well as a set of functions of belonging to fuzzy measurement results of each parameter. Conclusions. Thus, a method of identifying the state of fuzzy objects with a fuzzy non-productive output mechanism is proposed, the complexity of which does not depend on the dimension of the task.

Fiduciary is the transfer of ownership rights of an object based on trust, where ownership right of the object is transferred remains under the control of the owner of the object. The subject of the research was how to bind the object of fiduciary guarantee according to Law Number 42 of 1999 on fiduciary? What are the consequences if the binding of fiduciary guarantee object is unfulfilled? This research was normative legal research which means that the objects are secondary data on library. The type of the research was descriptive. It can be concluded that the binding of fiduciary guarantee object according to Law Number 42 of 1999 on fiduciary guarantee is certificate of fiduciary guarantee as an evidence which is an authentic deed. It can be seen from the characteristics of certificate fiduciary guarantee, issued by an authorized official or public official who has authority for issuing certificate fiduciary guarantee in Fiduciary Registration Office under the supervision of the Ministry of Law and Human Rights. The consequences (the binding of fiduciary guarantee object is unfulfilled) are the default causes several legal consequences for debtors and creditors, especially for creditors who must loss. While for debtors, the legal consequence is the existence of a new status for which the debtor must responsible of. Fiduciary guarantee, mostly in form of movable objects, allows for a transfer of fiduciary guarantee; one example of the reason for the transfer is the debtor wants to transfer his credit to another creditor to seek for lower interest. Then, if a debtor has paid off the debt, it can cause the fiduciary guarantee to be canceled.

Knowledge visualization (KV) and knowledge representation (KR) are distinguished, though both are knowledge management processes. Knowledge visualization is subject to humans, whereas knowledge representation – to computers. In computing, knowledge representation leverages reasoning of software agents. Thus, KR is a branch of artificial intelligence. The subject matter of KR is representation methods. They are classified into (1) knowledge level and symbol level representations; (2) procedural and declarative representations; (3) logic-based, rule-based, frame- or object-based representations (supporting inference by inheritance); and (4) semantic networks. In legal informatics, methods of legal knowledge representation (LKR) are dealt with. An essential feature of LKR is the representation of deep knowledge, which is mainly tacit. It is easily understood by professional jurists and hardly by amateurs from outside law. This knowledge comprises the teleology of law and a whole implicit framework of legal system. The paper focuses on (1) identifying key features of KV and KR in the legal domain; and (2) distinguishing between visualization, symbolization, formalisation and mind mapping.

There are four groups of indicators influenced on the performance of retail commercial enterprise. They are characteristics of the store (retail space), store location, transport and pedestrian accessibility of the store and the attitude of buyers to the shop (customer metrics). The present paper is dealt with the influence of the fourth group- «customer metrics ". The authors of this article consider such factors of this group as: the work of salespeople and other staff; the internal atmosphere of commercial enterprise; the security area of the enterprise location; brand awareness; additional services. The article describes the application of the proposed approach to the assessment and change forecast of turnover depending on the studied factors using the method of fuzzy logic by the example of the results of such shops as "Ocean" and "Pervomayskiy", retail outlets "Gastronom" format "supermarket", Izhevsk. The authors define term-sets and membership functions for each client criterion. The rule base is also developed. The presence of aggregate functions is implemented by Mamdani logical inference, which uses the min-max composition of fuzzy sets. The adequacy of the proposed mathematical model is performed on the example of results forecasting of investigated stores activities "retail network " Gastronom " format "supermarket" (Izhevsk, Russia) using the software Matlab, and then comparing the calculated value of the average purchase with actual. Monitored client performance on the basis of a network "Gastronom" has also allowed the authors to develop recommendations for shops as described in this article.

The article examines one of the unique aspects of design – the national component. The history of design demonstrates to us the importance of the national component in the formation of object-based shaping, its development in the industrial and post-industrial eras. In the conditions of post-industrial design, the role of the national component is growing and is increasingly revealed in its various directions, from object design to design of the urban environment. Through the prism of the interaction between national and international components in design, we can scrutinise design’s entire history. Using specific examples, applying phenomenal-geographical and synergetic approaches, the authors formulate the main models of the evolution of the national component in the design of different countries. As a result, 6 models of interaction of the national and international components in the subject design of the twentieth century were identified. They are «the constant of the national component», «transformation (expansion) of the national component into the international», «synchronization of the national and international components», «replacement of the national component with the international», «conglomeration of international and national components», «autonomy of national and international components». Graphic visualizations of models of countries – design nations are presented on the example of Japan, USA, Germany, Italy and Scandinavia.

An experimental/analytical study has been conducted to determine the performance improvements achievable by circumferentially indexing succeeding rows of turbine stator airfoils. A series of tests was conducted to experimentally investigate stator wake clocking effects on the performance of the space shuttle main engine (SSME) alternate turbopump development (ATD) fuel turbine test article (TTA). The results from this study indicate that significant increases in stage efficiency can be attained through application of this airfoil clocking concept. Details of the experiment and its results are documented in part 1 of this paper. In order to gain insight into the mechanisms of the performance improvement, extensive computational fluid dynamics (CFD) simulations were executed. The subject of the present paper is the initial results from the CFD investigation of the configurations and conditions detailed in part 1 of the paper. To characterize the aerodynamic environments in the experimental test series, two-dimensional (2D), time-accurate, multistage, viscous analyses were performed at the TTA midspan. Computational analyses for five different circumferential positions of the first stage stator have been completed. Details of the computational procedure and the results are presented. The analytical results verify the experimentally demonstrated performance improvement and are compared with data whenever possible. Predictions of time-averaged turbine efficiencies as well as gas conditions throughout the flow field are presented. An initial understanding of the turbine performance improvement mechanism based on the results from this investigation is described.
