TECHNIQUES AND ALGORITHMS OF INTERACTIVE AUGMENTED REALITY VISUALIZATION: RESEARCH AND DEVELOPMENT
DescriptionThe author performed a research with the purpose of improving visualization of three-dimensional objects by means of augmented reality technology with the use of massively available mobile devices as a platform. This article summarizes the main results and provides suggestions for future research. Since graphical user interfaces made it to the consumer market about 30 years ago, interaction with the computer has not changed significantly. The focus of current user interface techniques is only on human-computer interactions, not on human-real world interactions. With that in mind, the concept of augmented reality appears very promising. Besides other improvements, it provides a better user interface for visualization of virtual objects in real environments. Modern smartphones and tablet computers, as well as improved software tools have provided the prerequisites for mass usage of handheld augmented reality. The following issues were raised by research: realistic object rendering, the ability to change object parameters in real time, storing of objects, manipulation of objects in space, issues of augmented reality graphical user interface design

Description
The aim of the work is theoretical and experimental confirmation of the possibility of improvement in tractor unit acceleration due to the variable inertia moment of the rotating masses of the engine. The use of high-speed tractors in agricultural production meets a number of difficulties associated with unsteady processes during acceleration of the tractor units. The emerging significant inertial loads during acceleration result in the loss of engine power because of what the machine and tractor unit is operating at reduced productivity and efficiency. An analysis of published works shows that the tractor unit acceleration is strongly influenced by the rotating mass of the engine. A device based on the application of additional rotating masses in a free flywheel connected or disconnected automatically to the main engine flywheel at appropriate stages is offered. As a result, the tension during acceleration is reduced. The results of experimental studies on the effect of the additional rotating masses on the engine acceleration characteristics of the machine and tractor units on the basis of Class 1.4 tractor are given. It is proved that the use of the tractor additional rotating mass connected or disconnected to the respective modes of movement of a machine and tractor unit to the flywheel of the engine, improves acceleration performance

HISTORICAL ASPECTS OF EVALUATION IN ACCOUNTING
DescriptionThe assessment of objects of accounting is important for obtaining objective information on an economic and financial position of the organization. At the solution of a question of assessment methods in modern conditions, it is necessary to know how these issues were resolved earlier. In this article, we consider historical aspects of an assessment in accounting. The retrospective of the solution of this question is given, beginning from the XIII century in various countries – Italy, France, Great Britain, Germany, Holland, the USA, etc. Various points of view on assessment questions are considered. It is specified, that with the advent of a monetary assessment there was a double record. Types of estimates are considered: at the acquisition price (historical), at the sale (market) price, at prime cost, at recovery cost, at the reproduction price, a multiple assessment (for each asset of balance to use the base of an assessment), at fair value. Their positive and negative sides are given. The option of an assessment and revaluation of assets in the conditions of inflation with need to correct the wholesale prices of an inflation index is reflected. The main historical stages of development of an assessment – naturalistic, origin and distribution of a monetary assessment, distribution of market and historical estimates, development of variety of estimates, an assessment regulation, and association of various estimates in the category of “fair value” are formulated

HISTORY OF EVALUATION IN RUSSIAN ACCOUNTING
DescriptionThe assessment and calculation of objects of accounting is important for obtaining objective information on an economic and financial position of the organization. Requirements imposed to an assessment reveal: the assessment of all objects of accounting has to be real and uniform. It is specified obligation of an assessment of objects of accounting in monetary value – in rubles of the Russian Federation. At the solution of a question of assessment methods in modern conditions, it is necessary to know how these issues were resolved earlier. In this article, we have considered historical aspects of an assessment in accounting in Russia. The points of view of various scientists on questions of an assessment and accounting are given. It is specified, that in Russia, the development of the state and monastic farm was an incitement to development of accounting. Thus in trade at the accounting of goods the account method on each party with the cost scheme of registration of the facts of economic life prevailed. It is noted, that at that time most of accountants adhered to the principle of an assessment at prime cost. The special attention is paid to the development of the agricultural account. The points of view of unigrafists and digrafists on problems of an assessment and calculation are considered. Discussion concerning an assessment and revaluation of fixed assets is shown. The criticism of an assessment on labor units and other natural measuring instruments is presented. We have also substantiated the need of an assessment of biological assets at fair value locates
