Abstract In today’s society, communication is becoming more and more important. However, communication equipment is subjected to the vibration caused by wind in communication tower for a long time. In this paper, the inductive methods of vibration normalized spectrum for the equipment on the tower are introduced. Combined with the characteristics of communication tower, based on the current national military standards and some related papers, the random vibration environment data from communication tower can be inductive and processed. The energy distribution of the spectrum is compared with that of the European standard. The measured spectrum by induction is used in engineering tests, it also has laid a foundation for improving the reliability of the relevant equipment on the communication tower.

Main Thing

The article deals with the negative trends in the development of school mathematics education in the context of the relationship of inductive and deductive methods of teaching educational material. It is stated that the dominance of deduction in teaching of mathematics in high school and its separation from inductive explanations to students of mathematical concepts, definitions, rules, formulas indicates a complete disregard for pedagogical experience and K.F. Lebedyntsev and D. Polya’s methodical research. The historical causes of excessive application of the deductive method of teaching mathematics are revealed: the centuriesold practice of imitating the method of “Beginnings” by Euclid; historically short (about four centuries) period of induction method formation in scientific research; even shorter period of pedagogical induction applications practice. In order to more fully revealing the pedagogical significance of inductive methods of teaching mathematics, a brief analysis of the methodical features of lectures course on algebra, developed and delivered by I. Newton to the students of Cambridge University, was carried out.It is found out that this course has a strong inductive orientation and revealed this genius English scientist’s conviction that teaching mathematics is an art in which solving examples and problems is more important and useful than rules. It is emphasized that this I. Newton’s conviction was significantly ahead of other Western European mathematicians. The purposefulness and persistence of national mathematicians-teachers M.G. Kurganov, F.I. Busse, P.S. Guriev, O.M. Strannolyubsky, S.I. Shohor-Trotsky, K.F. Lebedyntsev in substantiating the pedagogical significance of the inductive method of teaching mathematics and its practical implementation were noted. The important general didactic significance of F.I. Busse’s views on the implementation of learning consciousness principle has been revealed. Examples of M.M. Luzin’s high school education and modern practice of training mathematics teachers are given. They show that the lack of inductive explanations of the main thing in the content of the lesson turns deductive learning into formal-deductive, accompanied by the substitution of understanding by thoughtless mechanical memorization of educational material. The exceptional relevance of the practical implementation of the methodical heritage of K.F. Lebedyntsev and D. Polya’s in the context of solving the problem of improving the quality of school mathematical education is substantiated. The most important task of of the considered problem – determinating the practical ways of its decision – is formulated.

We have performed comparative numerical calculations using a multiple trapping (MT) formalism with an exponential and an aggregate two-exponential trap distributions for describing two mostly used experimental setups for studying the radiation-induced conductivity (RIC) and the time-of-flight (TOF) effects. Computations have been done for pulsed and long-time electron-beam irradiations in a small-signal regime. Predictions of these two approaches differ appreciably in both setups. The classical MT approach proved very popular in photoconductive polymers generally and in molecularly doped polymers in particular, while a newly proposed complex MT worked well in common polymers. It has been shown that the complex MT successfully accounts for the presence of inherent deep traps, which may or may not have an energy distribution.

Islamic education method is the way used to achieve the objectives of Islamic education. According to Ahmad Tafsir view, Islamic education methods that are relevant and effective in Islamic education are drakronis method, synchronous-analytical method, problem solving method, empirical method, deductive and inductive methods. Drakronis is a teaching method that has prominent in history aspect. Synchronous-analytical method is a Islamic education method that provides theoretical analysis capabilities that are very useful for the development of mental faith and intellectual. Problem solving method is a method with approach of the students’ study to find a variety of problems by finding the solution. Empirical method is a method of teaching that allows students to study Islam through the realization and internalization of norms and principles of Islam through an application process which leads to a social interaction. Inductive method conducted by educators by doing a special material to the general conclusion. While Deductive method conducted by educators in the teaching of Islam by showing the general rules and then break them with a variety of examples of problems that become unraveled.

Aim/Thesis. Important for all the Christian confessions, spiritual autobiography has, unfortunately until now, been insufficiently investigated and highlighted by contemporary researchers. Concept/Methods. Therefore, using information from sources like Confessions of Saint Augustin, but also recent works like the one of Saint Silouan from Athos, Saint John of Kronstadt or Nicolas Berdiaev, using these representative sources for the Orthodox sphere and other volumes, studies and articles, we will try to analyse this genre, to emphasise its interdisciplinary valences, and to show which are landmarks in the Orthodox sphere. We will also try to present its particularities here, its common points with other confessional spheres (Catholic or Protestant), and its practical importance for the Christian life. The information provided by the aforementioned sources will be investigated using deductive, analytic, and inductive methods (and also, the narrative one when the situation will request it).  Results and conclusion. The investigation will show to the reader why, despite of the fact that is a peripheral genre of Theological literature, spiritual autobiography is important for investigation and it helps to create bridges between different spiritualties and investigation domains, but also its potential practical use. Originality/Cognitive value. The analysis is also important because there we will show that, a long time before the rediscovering of subjectivism and subjectivity in literature (which happened in the 20th century, with Modernism), in the theological space this topic was not only known but also valorised in this genre. As methods, we will both use the deductive and the analytic, but we will also not neglect the narrative one.

We propose a new SAT-based model checking algorithm to solve the reachability problem of real-time systems. In our algorithm, the behavior of region automata is encoded as Boolean formulas, and hence any SAT solver can be used to explore the region graph efficiently. Although our SAT-based algorithm performs better than other algorithms in flaw detection, it is less effective in proving properties. To overcome the problem, we incorporate a complete inductive method in our algorithm to improve the performance when the property is satisfied. We implement both algorithms in a tool called xBMC and report experimental results. The experiments show that the combination of efficient encoding and inductive methods offers an effective and practical method for the analysis of timing behavior.

Cost Of Construction

In the world of the construction industry, the wages of workers are quite large, which is about one-third of the construction value. So the company should pay serious attention to the wages of these workers. However, information regarding the wages of construction workers is only in the form of daily wages for casual workers and monthly wages for permanent workers, while information on the cost of workers' costs is not available. This study aims to identify the components of labor costs and their proportion to the overall cost of construction workers wages and to identify factors related to wages and costs of construction workers. In this study the method used is empirical and inductive methods, then the data obtained is processed and analyzed using descriptive statistics and comparative analysis. To model the burden of labor costs into its components and their respective proportions, descriptive statistical methods are used, while to analyze the variables -variables that affect wages and costs of workers used comparative analysis method. From the results of data processing, conclusions are drawn using the inductive method as follows: 1) The costs of workers are grouped into direct and indirect costs, and conditional costs, but the distribution of each cost component between permanent workers and freelancers is different; 2) Company profile, project profile, and worker profile. have an effect on wages and costs of construction workers.

The energy distribution in an electron; beam from an electron gun provided with a biased Wehnelt cylinder was measured by a retarding potential analyser. All the measurements were carried out with a beam of small angular divergence (<3xl0-4 rad) to eliminate the apparent increase of energy width as pointed out by Ichinokawa.The cross section of the beam from a gun with a tungsten hairpin cathode varies as shown in Fig.1a with the bias voltage Vg. The central part of the beam was analysed. An example of the integral curve as well as the energy spectrum is shown in Fig.2. The integral width of the spectrum ΔEi varies with Vg as shown in Fig.1b The width ΔEi is smaller than the Maxwellian width near the cut-off. As |Vg| is decreased, ΔEi increases beyond the Maxwellian width, reaches a maximum and then decreases. Note that the cross section of the beam enlarges with decreasing |Vg|.
