Ways to determine reliability in the operation of ship parts made by banding method

In the development of modern shipbuilding conditions and the repair of ship units, a special role is given to the use of basic structural elements consisting of technological parts. When performing these steps, it is important to analyze the properties of the materials from which the technological components of ship equipment are made. Testing should be close to the operating conditions of ship axles and shafts, namely cyclic loading, aggressive and adhesive environment. Therefore, a special factor is the technological control over the sequence of manufacture, selection of materials, surfacing technology. All these requirements can be analyzed and predicted using computer modulation. Investigations of the properties of the transition layers of the weld and the base metal and their effect on the number of load cycles in the tests are also key. All conditions will be met with the optimal selection of the chemical component Ni - Cr, which provide the required level of doping. The hardness of the materials is ensured by the presence of Mg in the metal. Also important are the heat treatment modes that provide the desired final structure of the material for machining and surfacing. For this part and its elements, the best properties in terms of operation in fine austenitic and pearlitic structures. During the operation of ship shafts and axles, the propagation of puncture loads is performed due to the occurrence of final stresses at low-cycle and multi-cycle loads and subsequent fatigue of the structural lattice. When considering the range of materials used in combined structures is very large and includes most welded steels. According to the combination of materials in one unit, it is advisable to distinguish two main groups of structures: with welded joints of steels of the same structural class, but different alloying, and with welded joints of steels of different structural classes. In this regard, the decision to obtain a balanced bandage connection lies in obtaining a fine-grained structure of the weld metal and the seam area.

Genomic Selection Using Environmental Covariates Within an Integrated Factor Analytic Linear Mixed Model

This paper introduces a single-stage genomic selection approach which directly integrates environmental covariates within a special factor analytic framework. The factor analytic approach of Smith et al. (2001) is an effective method of analysis for multi-environment trial (MET) datasets, but has limited biological interpretation since the underlying factors are latent so the modelled genotype by environment interaction (GEI) is observable, rather than predictable. The advantage of using known environmental covariates, such as soil moisture and daily temperature, is that the modelled GEI becomes directly interpretable, and thence predictable. This paper develops a model for both predictable and observable GEI in terms of a joint set of known and latent factors, as well as non-genetic sources of variation within trials and environments. This single-stage approach is referred to as the integrated factor analytic linear mixed model (IFA-LMM). The IFA-LMM is demonstrated on a late-stage cotton breeding MET dataset from Bayer Crop Science. The results show that the environmental covariates explain 34.6% of the genetic variance across environments (compared to only 23.3% for a conventional regression model). This represents 92.7% of the crossover GEI. The latent factors then explain 40.7% of the genetic variance, which represents 87.6% of the non-crossover GEI. This demonstrates the ability of the IFA-LMM to model crossover and non-crossover GEI in a manner that is both informative and practical to plant breeding.

Design of bakery products for healthy nutrition using plant raw materials

Nutrition is a special factor in maintaining health. Studies by domestic and foreign scientists indicate the relationship between nutrition and the most common non-communicable diseases. This specificity determines the need for specialized products for various categories of the population with genetic changes, existing diseases or characteristics of the living environment. Bakery products are regularly consumed in the diet of the Russian population. The latest market trends are the growing demand for bakery products with cereal additives for dietary and diabetic purposes. An integrated approach to solving the problem is provided through research in the design of recipes and technologies for new types of bakery products, including through the use of new plant raw materials. Chia seeds contain essential amino acids, vitamins (mainly B), minerals (calcium, potassium, iron, magnesium, phosphorus and zinc) and antioxidants. The use of chia seeds as a vegetable component in the technology of bakery products allows obtaining a product that combines not only high organoleptic properties, but also enriched with minor food components. Analysis of the chemical composition of the brioche buns (brioche) made it possible to conclude that the products produced with the use of chia seeds have a high nutritional value. Thus, the content of dietary fiber in the model sample is 2 times higher than the values of the control sample, covering 10% of the daily requirement, the content of omega-3 and omega-6 polyunsaturated fatty acids satisfies the daily requirement by 87.9% and 19.2%, respectively. Studies of the effect of chia seeds on the organoleptic characteristics of a brioche bun (brioche) allow us to conclude that there is a pronounced effect of the ingredients introduced on the appearance, color of the crust and the state of the crumb, but does not lead to a change in the taste and smell of baked products. The effect of chia seeds on the quality of products during storage was determined

The significance of faith in the concept of integral knowledge of Vladimir Solovyov

The article examines the role and place of faith in the concept of Vladimir Solovyov who is considered to be the creator of the first Russian philosophical system. The purpose of the article is to determine the epistemological and methodological significance of faith in Solovyov’s understanding as a special factor of cognition. In order to study this problem, a synthetic method of reconstruction of the thought of Solovyov as well as a method of philosophical analysis was used. First, Solovyov’s project of integral knowledge or free theosophy is presented, i. e. synthesis of philosophy, theology, and science. The suppositions of this concept are revealed and its polemical context is indicated, namely, Solovyov’s attempt to overcome the abstract or one-sided principles: reason, empirical experience, and faith in order to create an integral system that should unite all types of knowledge. In addition, philosophy as such corresponds to reason, science to experience, and theology to faith. The second part of the article is devoted to the epistemological aspects of faith in the concept of integral knowledge. It lies in the fact that each act of cognition begins with the assertion of the objective existence of its object, which Solovyov describes as faith in a broad sense of the word. Thus, faith has a universal significance as a necessary condition for the cognitive process. The third part of the article discusses the methodological aspect of faith as a key link in the system of integral knowledge. As a result, faith has a dominant role not only in theology, but in all spheres of knowledge, including philosophy and science. Thus, it is possible to conclude that there is no conflict between faith and reason; on the contrary, they complement each other. Solovyov’s position is still relevant nowadays.

Approximation of Linear Sets in the Plane

A few general lines in the ordinary Euclidean plane are said to be line generators of a plane linear set. To be able to say that every line of the set belongs to one-parametrical line set we have to find their envelope. We thus create a pencil of lines. In this article it will be shown that there are a finite number of pencils in one linear set. To find a pencil of lines the linear parametrical approximation is applied. Almost all of problems concerning the parametrical approximation of figure sets are well known and deeply developed for any point sets. The problem of approximation for non-point sets is an actual one. The aim of this paper is to give a path to parametrical approximation of linear sets defined in plane. The sets are discrete and consist of finite number of lines without any order. Each line of the set is given as y = ax + b. Parametrical approximation means a transformation the discrete set of lines into completely continuous family of lines. There are some problems. 1. The problem of order. It is necessary to represent the chaotic set of lines as well-ordered one. The problem is solved by means of directed circuits. Any of chaotic sets has a finite number of directed circuits. To create an order means to find all directed circuits in the given set. 2. The problem of choice. In order to find the best approximation, for example, the simplest one it is necessary to choose the simplest circuit. Some criteria of the choice are discussed in the paper. 3. Interpolation the set of line factors. A direct approach would simply construct an interpolation for all line factors. But this can lead to undesirable oscillations of the line family. To eliminate the oscillations the special factor interpolation are suggested. There are linear sets having one or several multiple points, one or several multiple lines and various combinations of multiple points and lines. Some theorems applied to these cases are formulated in the paper.

RESULTS OF RESEARCH OF RECTIFIER DIODES ON RESISTANCE

The article describes the study of rectifier diodes for resistance to special factors. The direct reverse current Iobr and the forward voltage of the diode Uobr were considered as a criterion for the performance of diodes. Based on the results of the calculation and experimental evaluation of the resistance of rectifier diodes to special factors, graphical dependences of the reverse current and direct voltage on the value of the special factor are constructed.

Density maps of geophysical study as a new type of integrated characteristic of geophysical fields in atlases

<p><strong>Abstract.</strong> Nowadays the geophysical section of traditional atlases is not sufficiently informative. The amount of geophysical fields’ maps rarely exceeds two. On the other hand, the electronic GIS atlases invariably include in their composition maps of study of geophysical observations, which make it possible to assess the level of exploration on the mapped territory. The creation and design of such maps today are limited to displaying only the factual location of observation profiles and other objects. In order to expand the possibilities of analyzing geophysical information, the authors suggests a method for creating of density maps of geophysical study. The study on these maps is shown with isolines &amp;ndash; usual method for geophysical maps. The authors of this article describe the method of creating density maps of geophysical study. This method includes the following steps: selection and analysis of information sources of geophysical study; choice of study parameters for mapping; calculation of the density of objects of geophysical study; interpolation and creation of isolines of objects of geophysical study density. The created study maps of density dynamics represent the approbation of the method; they allow increasing the information content of geophysical section of the atlas. The study is also a special factor that determines general need of mapping the phenomenon and characterizes the availability of data sources for mapping. Therefore, the opportunities for using developed maps for the automated determination of the atlas structure are also shown in the article.</p>
