The article raises the problem of classification of the concepts of computer science and informatics studied at secondary school. The efficiency of creation of techniques of training of pupils in these concepts depends on its solution. The author proposes to consider classifications of the concepts of school informatics from four positions: on the cross-subject basis, the content lines of the educational subject "Informatics", the logical and structural interrelations and interactions of the studied concepts, the etymology of foreign-language and translated words in the definition of the concepts of informatics. As a result of the first classification general and special concepts are allocated; the second classification — inter-content and intra-content concepts; the third classification — stable (steady), expanding, key and auxiliary concepts; the fourth classification — concepts-nouns, conceptsverbs, concepts-adjectives and concepts — combinations of parts of speech.

Objectives This paper sets out to provide a theoretical substantiation of the placement of external fire-prevention water supply sources when designing unique construction objects, for which standard requirements of fire safety cannot be applied. Problematic situations arising during the design of unique construction objects, which relate to the provision of the required level of fireextinguishing substances supply, are described.Method A model constructed on the basis of graph theory is presented for the preliminary calculation of the location of external fire-fighting water supply sources that takes the equipment of fire-rescue units into account. The utility of developing a universal mathematical model for the preliminary definition of arrangement parameters of sources of external fire-prevention water supply when designing construction objects is substantiated.Results Examples of preliminary calculation of the number of external fire-fighting water supply sources are given considering the shape of the building perimeter. Additional factors determining the distances from external fire-fighting water supply sources to the projected objects are given.Conclusion A conclusion regarding the adequacy of the proposed model is formulated and directions for future research indicated that allows the applicability of the model to be specified for the calculation of the projected objects, which differ in terms of dimensions given in the plan by above-normative characteristics.

In 1936 Turing invented a mathematical model of computation, known today as the Turing machine. He intended it as a representation of human computation and in particular as a vehicle for refuting a central part of David Hilbert’s early 20th-century programme to mechanize mathematics. By a nice irony it came to define what is achievable by non-human computers and has become deeply embedded in modern computer science. A simple example is enough to convey the essentials of a Turing machine. We then describe the background to Hilbert’s programme and Turing’s challenge—and explain how Turing’s response to Hilbert resolves a host of related problems in mathematics and logic. If I had to portray, in less than 30 seconds, what Alan Turing achieved in 1936 it seems to me that drawing the picture shown in Fig. 37.1 would be a reasonable thing to do. That this might be so is a testament to the quite extraordinary merging of the concrete and the abstract in Turing’s 1936 paper on computability. It is regarded by, I suppose, a large majority of mathematical scientists as his greatest work. The details of our picture are not especially important. As it happens, it is a machine for deciding which whole numbers, written in binary form, are multiples of 3. It works thus: suppose the number is 105, whose binary representation is 1101001, because (1 × 26) + (1 × 25) + (0 × 24) + (1 × 23) + (0 × 22) + (0 × 21) + (1 × 20) = 64 + 32 + 8 + 1 = 105. We start at the node labelled A and use the binary digits to drive us from node to node. The first couple of 1s take us to node B and back to A again. The third digit, 0, loops us around at A. Now a 1 and a 0 take us across to node C; and the final 0 and 1 take us back via B to A once more.

This chapter defines the algorithm as a critical concept across four intellectual strands, beginning with its foundations in computer science and the notion of “effective computability.” The second strand considers cybernetics and ongoing debates about embodiment, abstraction, cognition, and information theory. The third explores magic and its overlap with symbolism, engaging with notions of software, “sourcery,” and the power of metaphors to represent reality. The fourth draws in the long history of technicity and humanity’s coevolution with our cultural tools. Synthesizing these threads, the chapter offers a definition of the algorithm as culture machine in the context of process and implementation, and closes with a summary of the essential facets of algorithmic reading and a brief glimpse of algorithmic imagination.

The scope of the Theory of Scientific Change (TSC) encompasses any and all changes that occur in a given scientific mosaic, the set of all methods employed and theories accepted at a given time by a given scientific community. Currently, theory is defined as a set of propositions that attempts to describe something. This definition excludes normative propositions from the scope of the TSC. Normative theories, such as those of methodology or ethics, have been excluded since including them appears to give rise to a destructive paradox first identified by Joel Burkholder. There are many historical cases where employed scientific methods are known to conflict with professed methodologies. This seems to violate the third and zeroth laws of scientific change. By the third law, employed methods are deducible from accepted theories. But, this seems impossible in cases where methodologies and methods conflict. Under the zeroth law, all elements in the scientific mosaic are compatible with one another. But, that seems to be clearly not the case if methodologies and methods conflict with one another. In this paper, I argue that normative propositions such as methodologies can be included in the scientific mosaic as accepted theories without generating a paradox and that neither the third nor zeroth laws of scientific change need be violated. I outline my solution to the paradox of normative theories and conclude by describing some new and exciting avenues for future research that are now open.Suggested Modifications[Sciento-2016-0001]: Accept the following reformulation of the third law:The third law ≡ a method becomes employed only when it is deducible from some subset of other employed methods and accepted theories of the time. Consequently, accept that there is no paradox of normative theories: when an employed method and an accepted methodology are logically inconsistent with one another; it merely indicates that the employed method isn’t a logical consequence of the accepted methodology. By the third law, the employed method still follows from some accepted theories, but not from this particular methodology.  Reject the previous formulation of the third law; it can remain in use for educational purposes. [Sciento-2016-0002]: Provided that the preceding modification [Sciento-2016-0001] is accepted, accept the following taxonomy for theory, descriptive theory, normative theory, and methodology:Theory ≡ a set of propositions.Descriptive theory ≡ a theory that attempts to describe something.Normative theory ≡ a theory that attempts to prescribe something. Methodology ≡ a normative theory that prescribes the rules which ought to be employed in theory assessment.Modify the definition of theory acceptance to make it possible for both descriptive and normative theories to be accepted:Theory Acceptance ≡ a theory is said to be accepted if it is taken as the best available description or prescription of its object. Reject the previous definitions of theory, methodology, and theory acceptance.

Due to the continuous development of the building-and-construction industry, it is necessary to design new or modify outmoded industrial equipment. Using jaw crushers with the impact action of crushing plates on material is a perspective line of developing crushing equipment. Purpose. Developing a mathematical model of a vibratory jaw crusher and studying the operational process which is based on the mathematical model in order to design new crushers. Methodology. Definition of the crusher working process is based on the main statements of the theory of mechanical oscillations and the theory of continuous environment. In the motion equations of the crusher the material is taken into account on the basis of a discrete model by a continual parameter. Findings. A physical model is developed on the basis of which motion equations are derived, which include three main conditions of the efficient operation: 1) the elasticity of the second vibrating element must exceed or be equal to crushing force; 2) vibrations of the first and the third vibrating elements must be in phase, and vibrations of the second vibrating element must be in antiphase; 3) the summarized displacement of the second and the third crushing plates must ensure crushing of material. Graphs of the effect of the vibrating elements and elasticity coefficients of elastic systems on the amplitudes of vibrations are plotted and analyzed. On the basis of the motion equations, with consideration for the optimal parameters of the crusher vibrating elements and for the elasticity coefficients of the elastic systems, the amplitude-frequency characteristics of the crusher for different frequency ranges are determined. Set up is an equation describing the displacement of material in the crushing chamber for a time interval required for the crushing plates to be separated. Presented are graphs of dependency of the amplitude of vertical vibrations of the crusher casing on the elasticity of the isolating elastic system, and provided are recommendations for selecting and calculating vibration isolation. Originality. A mathematical model of an experimental vibratory jaw crusher and the characteristics of the experimental crusher are presented, on the basis of which recommendations are given for the selection of energy-efficient operating modes of the crusher. Practical value. Knowledge on the rational values of the frequency ranges for operation of the studied vibratory jaw crusher makes it possible to determine the optimal level of power consumed by the crusher and efficiency in processing materials of different hardness.
