Identification and Control of Multidimensional Delayed Processes in Conditions of Incomplete Information

Problems of identification and control of multidimensional discrete-continuous processes with delay in conditions of incomplete information about the object are considered. In such conditions, the form of parametric equations for various channels of the object is absent due to the lack of a priori information. Moreover, multidimensional processes have stochastic dependences of the components of the vector of output variables. Under such conditions, the mathematical description of such processes leads to a system of implicit equations. Nonparametric identification and control algorithms for multidimensional systems are proposed. The main task of modeling such processes is to determine the predicted values of the output variables from the known input. Moreover, for implicit equations, it is only known that one or another output variable can depend on other input and output variables that determine the state of a multidimensional system. In this study, a nontrivial situation arises when solving a system of implicit equations under conditions when the dependences between the components of the output variables are unknown. The application of the parametric theory of identification in this case will not lead to success. One of the possible directions is the use of the theory of nonparametric systems. The main content of the work is the solution of the identification problem in the presence of dependencies of the output variables and then the solution of the control problem for such a process. Here you should pay attention to the fact that when determining the reference actions for a multidimensional system, it is first necessary to solve the system of reference actions, since it is not possible to choose arbitrarily setting influences from the range of definition of output variables. Computational eXperiments aimed at investigating the effectiveness of the proposed identification and control algorithms are presented.

Adapting to Leadership in Offshore Schools: A Case Study of Sino-Nova Scotian Schools

A mixed-methods study including 22 Sino-Nova Scotian school principals in China has established that preparation for leadership in that context requires the consideration of many salient factors. While many North American standards of leadership are an important foundation, effective communication within the multidimensional system is of paramount importance. It was also found that, in order to administer a successful program, principals needed to build stronger social support systems for their teachers and further create a community of practice that included cultural sensitivity and understanding.

Ratio of the structure of hotel online booking channels and the monitoring of the quality of hotel websites in a multidimensional system

Purpose: The purpose of this paper is to explore the potentials that can positively impact the success of a hotel online business by: (1) exploring the specifics of the internal structure of online booking channels in the hotel business, (2) identifying the value and distribution of the potential to increase hotel bookings through the hotel website, (3) identifying the potential by exploring the space for improving hotel website excellence, and (4) developing an innovative multidimensional metric for monitoring hotel website quality. Methodology: This research was approached in a way that the issue is considered from two aspects. Firstly, the potential to improve the ratio value of the hotel online booking channel structure is observed. The survey in the Republic of Croatia was conducted by regions on a sample of 4* and 5* hotels. Secondly, the potential to improve a hotel business is considered as the possibility to improve the performance of a hotel website. Results: The research results show the value and distribution of the potential which can be used for a positive impact on the hotel business. Furthermore, the use of the presented multidimensional metric model allows a clear recognition of the potential for the hotel website quality improvement. Conclusion: It can be concluded that both aspects of the potential research (in addition to the research findings), open up numerous possibilities for conducting similar or more complex analytical procedures and a new empirical research.

METHODOLOGICAL ASPECTS OF TEACHING THE DISCIPLINE «PHILOSOPHY» IN THE FRAMEWORK OF DISTANCE LEARNING IN HIGHER EDUCATION

The paper analyzes the methodological aspects of teaching the discipline «Philosophy» in higher education in the situation of distance education and focuses on the need to preserve the holistic epistemological anthroposophical discourse and multidimensional, system-forming knowledge in the «digital» learning format.

El desarrollo de la efectividad comunicativa escrita en ELE: las arabófonas a examen

Communicative effectiveness in foreign language writing refers to the ability to dominate a multidimensional system that includes linguistic, sociolinguistic, and pragmatic knowledge. This work focuses on measuring the efficacy in Lebanese Spanish students’ writing throughout different stages. All students’ mother tongue is Arabic. For this purpose, a scale of measurement of communicative effectiveness has been applied in the texts written by 57 university students. The results attest an incidence of the level in the grammar domain, whereas this one does not seem to have an impact on the structure of the text, the recognition of the rhetorical situation or the selection of the ideas.
