Opis:
Artykuł przedstawia rozwinięcie metody wyznaczania wysokości niwelety toru kolejowego poddanego obserwacjom pochyleń za pomocą libelli elektronicznej. Metoda polega na całkowaniu funkcji opisującej zbiór nachyleń stycznych, a kluczowe znaczenie dla dokładności wyników ma rodzaj użytej funkcji. Autorzy zaproponowali w tym celu wykorzystanie funkcji sklejanych, pozwalających opisywać gładkie kształty z dobrym przybliżeniem. Opracowanie przedstawia opis metody, jej cechy charakterystyczne oraz wyniki testów dokładnościowych, pozytywnie weryfikujące założenia koncepcji.
The development of a method for determining the height of a railway track grade line subjected to an observation of inclinations with the use of an electronic level [3] is presented in the paper. The method includes integrating a function which describes a set of slopes of tangents, and the type of a used function is a key to accuracy. In order to determine the function, approximating polynomials or straight interpolation segments can be used. However, these methods introduce some simplifications which decrease the accuracy of the results. The authors therefore suggested the use of spline functions, which allow to describe smooth shapes with a good approximation. The study presents a general description of the method with specifying the characteristics associated with the use of spline functions (Chapters 2 and 3), as well as establishing a test experiment with the accuracy results (Chapters 4 and 5). Spline models were compared with straight interpolation segments, for which the accuracy falls within the recommended industrial standards [14]. The tests were carried out on three independent models (Fig. 3), and their results have been grouped in Tables 1 and 2. The obtained results positively verified the assumptions of the concept, resulting in a higher accuracy as compared with the straight interpolation model, allowing for precise determination of the height regardless of the grade line geometry changes.

Opis:
The article is devoted to defin the conceptual foundations of the study of socio-cultural lines of study literary reading of 5th grade students in the schools of national minorities of Ukraine. The purpose of the study is to identify the conceptual foundations of teaching literary reading in the schools of national minorities of Ukraine (in the framework of socio-cultural lines). Research methods. The main method of creating concepts was the inductive method, and the theoretical methods such as the analysis of philosophical, literary, methodological, psychological and pedagogical literature. The use of empirical methods are limited, among them, a pilot experiment was the main method. A didactic study of the implementation of socio-cultural lines in the context of teaching literary reading involves the deployment of conceptual research in three areas: methodological, theoretical and practical fields. In methodological concept, the status categories of activity and personality are defined. The doctrine of the activities of AK toils the value of different types of teachers and children’s activities, in particular training, their decisive role in the formation of personality in the process of literary reading in Ukrainian language. Understanding the nature of "the identity of the student" requires a teacher of literary reading of the 5th grade students of schools with national languages, in the learning process, to give the instruction for the personal self-development and self-realization through activity and communication in various social environments. The theoretical concept (general scientific and specifically-scientific concept) reflects the relationship and interaction of the various theories, approaches and principles of General scientific and specifically scientific nature in relation to the study of problems of implementation of socio-cultural lines of study of literary reading. The basic idea for solving the problem of realization of socio-cultural lines of study literary reading of the 5thgrade students in schools with national languages of instruction at the application level is to focus educational activities on creation of conditions for proper formation of sociocultural competence of the student through the discovery of the essential forces students to process their own activity and communication with adults and other children. Results: the study concept represented through three interrelated concepts – methodological, theoretical and applied, comprehensively ensures the implementation of the main idea of the study.
