In the article on the basis of numbers of the specific form, where the parameter elements, which form a semigroup under multiplication we have presented a method for determination and distribution of composite numbers and the prime numbers, and accurate calculation of the values of pi in the interval from 1 to N. We present a new algorithm for the distribution of primes. We have reached the law of distribution parameters of composite numbers and prime numbers (Distribution of the parameters of composite numbers and prime numbers (DCPN)). We have given a formula for of finding prime numbers by serial number in the set DCPN. Due to the law of distribution of parameters of composite numbers and prime numbers it becomes apparent disintegration set of prime numbers. We have also introduced a proposal that each element of the plurality of composite numbers can be represented by one of the specific types of works. The proof of Proposition 2 allows us to give one of the most effective ways of recognizing primes. The description of the algorithm for numbers of twins and proof of their infinity. All algorithms presented in the article is a listing of programs in Software Module ACCESS
It is shown that random events occurring on Earth and uniformly distributed in time, have a distribution, depending on the polar angle and radial coordinate in the plane of Earth's orbit. The general dependence of the density distribution functions in continuous and discrete case was obtained. It is shown that the social reaction of a large group of actors on the impact of celestial bodies can be described by a function of the root-mean-square deviation of the normalized frequency of choice, depending on the radial velocity or time derivatives of gravitational potentials of celestial bodies
In the article we consider experimentally-theoretical questions of distribution seeds with a pulse sowing device in laboratory and field conditions
The influence of a superficial plastic deformation and a corner of installation of a roller on the diagram of specific normal pressure and contact forces of friction is shown in the article
In this work, the example of skidding vehicle passes distribution along a skidding trail is considered. The distribution is determined when vehicle capacity is being decreased in skidding process because of rut depth increasing on the soils with low bearing capacity
In the training courses on the theory of probability and
mathematical statistics there are various parametric
families of distributions of numerical random variables
considered. Namely, we have been studying the
families of normal distributions, log-normal
distributions, exponential distributions, gamma
distributions, Weibull-Gnedenko distributions, etc. All
of them depend on one, two or three parameters.
Therefore, for a complete description of the distribution
it is sufficient to know or estimate one, two or three
numbers. Parametric theory of mathematical statistics is
widely developed, where it is assumed that the
distribution of observations belong to one or another
parametric family of distributions. This tradition comes
from Karl Pearson, who in the early twentieth century
proposed the use of four parametric family of
distributions. The above families of distributions - are
the subsets of a four-parametric family of Pearson.
Unfortunately, parametric families exist only in the
minds of the authors of textbooks on probability theory
and mathematical statistics. In real life, they are not.
Therefore, modern applied statistics and econometrics
mainly use non-parametric methods, in which the
distribution of observations can have arbitrary form.
First, on an example of a normal distribution, we are
discussing the impossibility of practical use of
parametric families of distributions to describe specific
statistical data. We give the results of research of
metrologists and estimation of convergence in limit
theorems. Then we discuss how the parametric methods
can use for reject outlying observations. It is very
unstable the significance levels for a fixed rejection rule
and the parameter of the rejection rules for a fixed level
of significance. Consequently, the rejection of the
classic rules of mathematical statistics is not sciencebased
The main indicators of the state of the dairy industry
of the Krasnodar region are given. The results of the
marketing research of consumers of the dairy
products market of the Krasnodar region are
considered. The article reveals reasons for dairy
products appeal, reasons for rejection of dairy
products, distribution channel structure, consumer
preferences for types of dairy products, the
frequency of purchase, the level of consumer
satisfaction by dairy products range, consumer
preferences for manufacturers of dairy products,
consumer opinion about the price and quality of
dairy products, characteristics of consumers portrait
by sex, age, education, occupation, place of
residence. The necessity of diversification of
activities of agricultural producers, which is a
process of allocating funds to be invested between
different objects of investment that are not directly
linked is substantiated. The possibility of processing
of milk by agricultural producers of the Krasnodar
region to meet the basic needs of the population and
guests of the Krasnodar region and the further
formation and development of the market of dairy
products in the region is pointed out. The investment
project for construction of a dairy plant is presented
and the prospect of its implementation and
compliance with consumer preferences is considered.
Negative trends in the dairy market are noted. The
prospects of development of the dairy products
market of the Krasnodar region are indicated
In this article, we have given the strategy of diversification
of agricultural production assuming addition of
traditional branches of specialization by new branches;
the priority direction of diversification of activity of
development of rural territories - construction of
greenhouses and cultivation of vegetables has been
described. The constructive calculations confirming
economic feasibility of the investments directed to the
diversification of activity of the enterprise connected
with cultivation of tomatoes in greenhouses are made:
range of prices for products is considered (tomatoes),
calculation of needs for investments is made, future
payments on the credit are calculated, need for personnel
of future project, potential efficiency of implementation
of the project on cultivation of tomatoes, the net
specified value of the investment project and the discounted
payback period (calculation of NPV and IRR
of the investment project) is defined, articles of expenses
are submitted, the main indicators of profitability
are considered, it has been defined as far as the
project is sensitive to change of cost of investments on
NPV indicator
In a competitive environment an effective measure of successful business management is diversification. This article discusses issues related to the expansion of the production activity of JSC "Slavprom" in the Slavic area. JSC "Slavprom" is a modern Vineyard and winery with a processing capacity of 6,500 tons of grapes per year. In the production activity of JSC "Slavprom" there is a number of problems: the low profitability of production; high levels of debt capital; insecurity own wine materials. As a way out of the crisis, the article examines the issues related to the expansion of industrial activity - the introduction of the production line of children's grape juice. This event will provide annually about 119.4 thousand. Liters of juice, and the five-year period - 597.0 thousand. L. Economic valuation of the project shows that the project is economically and socially effective, profitability is on average 23.3%. Discounted payback period at a discount rate of 14% is 20 months. Implementation of this project contributes entering new markets for JSC "Slavprom" with high quality and highly liquid products at an affordable price, replenishment at all levels and creating new vacancies
The article deals with key issues relating to energy efficiency in Russia, as well as the main directions of energy saving in agriculture
