Effective production activities of organizations is impossible without the concept implementation of the constant reproduction of capital assets, a significant part of which is represented by buildings and structures for various functional purposes. Increased deterioration of industrial buildings does not allow to solve such important tasks as improvement and automation of production processes in their entirety, and has a negative impact on the working conditions and safety of personnel. The analysis of scientific and normative literature is showed that the issue under consideration requires further research. Author’s approach to the reproduction of capital assets, the use of which allows to increase the management decisions efficiency on the basis of a complex of tasks for the joint estimation of damage and deterioration, planning of works under the given constraints with the use of mathematical apparatus and technological solutions for monitoring the technical condition of buildings is presented in the article.

In this Article I shall examine the visual form or appearance (shape, size, and other visible qualities) of Soviet socially produced things (excluding any detailed consideration of trends in the fine arts or of individual craftsmanship) in relation to forces in Soviet ideology which seem to have influenced this form or appearance. (I do not attempt to describe all influences which bear on Soviet design, which would require a much more complex approach and a more extended treatment.) My definition of Soviet “ideology” would be the same as Professor Meyer's: the body of doctrine that is taught by the Communist Party to all Soviet citizens. Whether or not this doctrine is true, or thought to be true, as well as why it is propagated, or whether this would be a complete definition—these questions are considered to be irrelevant in the present context.

Raising of problem. The methodology presented in this study is aimed at modeling the variability of the technical condition when operating a car in a complex social and technical system "car − person − environment". This allows you to simulate the change in the operational properties of the car depending on its operation, affecting the change in the technical condition by the Functional Resonance Analysis Method (FRAM). Purpose. The variability of the technical operation of the car needs to be managed, and not reduced or eliminated, since this is an advantage, as well as conditions for the safety and functioning of complex socio-technical systems. To control it, you must first monitor the variability of the vehicle's technical operation. A set of relevant indicators needs to be identified and developed. Their interpretation makes it possible to draw conclusions about the level of technical condition, operational properties of the vehicle and traffic safety and supports the prediction of the occurrence of future events (failure occurrence). Conclusion. Thus, the basic principles of the FRAM for modeling the variability of the technical condition when operating a car in a complex social and technical system "car − person − environment" have been determined. The relationship has been established between the definition of traffic safety, the FRAM model and the performance indicators of the vehicle. The developed model of the FRAM for maintenance of the undercarriage of cars, consisting of a set of functions that describe the actions taken to maintain cars to ensure their good condition. A block diagram of the implementation of functionally oriented technologies for the maintenance and repair of cars has been developed, taking into account the design features and the level of technology for technical influences. This allows you to objectively determine the required scope of maintenance work, depending on the results of diagnostics and the availability of technological equipment.

AbstractWe generalize Löwner's method for proving that matrix monotone functions are operator monotone. The relation x ≤ y on bounded operators is our model for a definition of C*-relations being residually finite dimensional.Our main result is a meta-theorem about theorems involving relations on bounded operators. If we can show there are residually finite dimensional relations involved and verify a technical condition, then such a theorem will follow from its restriction to matrices.Applications are shown regarding norms of exponentials, the norms of commutators, and “positive” noncommutative ∗-polynomials.

Throughout studying of a problematics of conscientiousness in article the question of legislative fastening of a category of conscientiousness from the point of view of various approaches is considered. Considering the complex approach necessary in questions of legal definition of the maintenance of this or that category, the author insists on introduction of concepts of conscientiousness, the diligent tax bearer, a presumption of conscientiousness not only and it is not so much within the limits of separate norms and articles, how many on necessity of reduction of maintenance НК the Russian Federation according to them. The legal regulation in such context when conscientiousness is a letter and spirit of the law, demands revision of set of its positions, concerning legal status of tax bearers, tax departments, tax agents, banks, a legal regulation of actions of tax control and consideration of their results, the tax information etc. Hence, for the author it is a question of giving to legal regulation of a certain orientation, a formulation new концепта, according to which: 1) the diligent person always has advantage before unfair, and the more so before the defaulter; 2) the diligent person cannot be put in the worst position, than unfair; 3) granting of tax privileges demands a recognition of the person the diligent; 4) application of special tax modes is put in direct dependence on a recognition of the person by the diligent. Thus, in a basis of legal regulation of a principle of conscientiousness the author puts the approach based on a recognition of a difference of legal status of persons depending on execution by them of a duty on payment of taxes that, in its opinion, to the greatest degree corresponds to taxation major principles — compulsions, generality, equality and justice.

With the introduction of the Russian laws on the definition of safety in use of buildings and structures, it became necessary to develop criteria (coefficients) for estimating these states. One of the known approaches to assessing the safety of buildings is based on the analysis of geometric characteristics. However, currently, there are no criteria that would ensure the solution of this problem. It is required to develop these characteristics. In this research, we offer an approach to the designation of such criteria. This proposal for assessing the technical condition of buildings, the coefficients of internal geometry and building stability, providing a single-value assessment of the state of the object in terms of safety of its use.

The analysis of Russian and foreign literature on the definition of somatic sex on the skull is presented. Cranioscopic and craniometric approaches are considered in carrying out craniological studies and existing traditional and modern methods for their implementation. Cranioscopic studies reveal the advantages and disadvantages of W.M. Krogman, G. Acsadi, J. Nemeskeri and V.N. Zvyagina methods. It is shown that the method of V.N. Zvyagina, which includes 40 descriptive diagnostic signs, is the most informative. Its efficiency is 93,5%. The comparative analysis of the craniometric methods for studying the skull according to R. Martin and H. Welcker in the modification of A.P. Bogdanov and a number of English craniologists is presented. The authors point out that the Russian Forensic Center developed a craniological form, which includes 79 different sizes of a skull, by which is possible to determine not only the sex of a skull, but also the approximate age of a person. A comparative assessment of the Russian (V.I. Pashkova) and foreign (E. Giles) craniometric studies is presented. According to V.I. Pashkova using only craniometric techniques allows one to determine the sex of the skull only in 75-80%, and in the complex approach - in 80-93%. The method of E. Giles, based on the study of regression equations, is objective in 83-86%. Thus, studies of the sex determination by skull in an adult should be comprehensive, including both cranioscopic and craniometric techniques.
