An analytical synchronization for data of the transport diesel engines working process is a key issue of this publication. Of particular importance is that workflow data refers to engines in use. The lack of accuracy in determining the current characteristics of the working process is the cause of a significant error in determining power, fuel consumption, errors in monitoring the operation of engine systems, and its diagnosis. Calculation of the effective power of marine diesel engines is necessary not only to control the workflow and diagnose problems. It is also important for energy efficiency management as part of the Ship Energy Efficiency Management Plan (SEEMP). The task of analytical synchronization is formulated as the transfer of data of a function by time to a function by the angle of rotation of the crankshaft. In this case, it becomes possible to determine the top dead center (TDC) most correctly. As the basis of the method of analytical data synchronization for determining TDC coordinates, it is proposed to use the sequential execution of three stages: linear, sinusoidal, and differential (compression pressure’s first derivative is equal to zero). In addition, refinements have been made to linear and sinusoidal synchronization algorithms. They differ from their existing counterparts in using detailed restrictions. This allows one to have a further reduction of the error in TDC determining to a range of 0.1 ... 0.3 degrees of the crankshaft rotation. Also, this ensures the accuracy of the indicated power calculation and other basic workflow parameters with a maximum relative error of up to 2.5%. Obviously, such high accuracy allows avoiding diagnostic errors as much as possible, predicting the engine load, performing more exact calculations of parameters and characteristics, and taking measures to achieve higher energy efficiency and economy. Undoubtedly, this helps to increase the efficiency of both transport engines in general and marine engines in particular.
The article is devoted to the methodological foundations of preparing the intending philologists for the implementation of crosscultural communication. Based on the analysis of various sources, the essence of the concepts «crosscultural communication», «crosscultural communicative competence», the main conditions for successful intercultural communication are revealed. It is determined the ways of formation of the «secondary linguistic personality» of the intending teacherphilologist for effective cross-cultural communication, taking into account the increase in the level of methodological training of a specialist. This training is provided by the organization of educational process in a higher pedagogical educational institution on the basis of communicative-active and culturologicalapproaches by disclosing the creative potential of a student identity. The educational process is carried out through the means of a foreign language, selfsearch activities, learning cultures of native and English-speaking countries and comparing these countries through the prism of the language, using the potential of Internet technologies. Internet is a tool to intensify the educational process and unrestricted access to authentic sources, a tool of using the potential of a foreign language lesson to accomplish tasks that imply the ability of the intending philologists to apply situations with the domination of problematic, communicative tasks and reliance on a functionally adequate text.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
