The effect of auto-displacement in a resonant-tunnel diode (RTD) on the dynamic range of amplifiers on these diodes is considered. Taking into account autosplacement, two possible types of amplitude characteristics and boundaries of their existence were revealed. For these two types of amplitude characteristics, expressions were obtained that determine the dynamic range of the amplifier. When using the amplitude characteristic of the first type, the auto-shift expands the region of existence of this amplitude characteristic and leads to a decrease in the dynamic range. For amplitude characteristics of the second type, a certain expansion of the dynamic range can be achieved.

Keywords: a resonance-tunnel diode, a current-voltage characteristic of a diode, a dynamic range, a gain factor, the degree of regeneration, and the power supply mode of an amplifier for an RTD.

In this day and age the application of scientific and engineering inventions may further an effective solution of import substitution and increase in labor productivity. Invention is a new technical solution, having essential differences and a positive effect (new technologies, designs, substances). For instance, the technical result of the invention ""The production method for wire reinforced composite (RU 2619606)"" is the increase in durability of the reinforcing net due to the increase in binder adhesion to the bars, increase in thermal resistance of the net, and the use of simple production equipment. Practical implementation of this invention makes it much easier (unlike its prototype) toproduce wire reinforced composite under the conditions of a specialized enterprise.

The ultimate goal of the activities of the woodworking company is receiving income from the use of forest resources. To achieve a normal level of profitability is not enough of one evaluation of the taxonomic indicators the forest area. This article describes the methodology of assessing the economic availability of forest resources based on analysis of all the key factors such as: cost of logging, transport accessibility, the cost of creating the necessary infrastructure. A study of the process of logging one of the largest woodworking enterprises of the domestic timber industry for availability of forest resources. It is concluded that the different forest areas of the plant are characterized by different initial conditions. Accordingly, this guidance on tactical and strategic planning in the field of improvement of economic availability of forest resources, it is noted that the plots with higher level of affordability should be developed at an accelerated pace, and the areas with less favourable economic performance should only fill in missing volumes.

An inportant and challenging task for a market analyst is to predict a value or a direction of a certain indicator based on the behaviour of a given financial instrument. In this paper we use random forest algorithms to predict a value and a direction of an implied volatility of RTS index options. We collect and prepare the historical data with an algorithm which takes into account both the actual trades history and the ordlog. We then examine and use the effect of volatility clustering which can be observed on such options. Finally, we construct some simple option trading strategies based on the predictions we made and measure their performance on a subset of our historical data. The results obtained shows that such approach can of use as one of the mechanisms for making decisions in practical trading, and needs further research.

the article presents an overview of the most common ways of measuring the volume (mass) of bulk materials currently used in various industries. The comparative analysis presented in the article methods of assessment. It is established that current methods of calculating volumes of granular media have a number of disadvantages, which significantly affects the quality of the product and its value. It is revealed that it is most expedient to carry out measurement of the volume of granular media directly in the containers or the vehicle taking into account the main characteristics of the material — moisture content, bulk and true density, temperature and fractional composition.

Stable functioning of the organizational structure under external influence, volatile external environment, internal changes and restrictions determined by the ability to forecast the head of the emergence and development of crisis situations and effectively influence them. We propose a model of the possible schemes for generating a crisis of development and the achievement of objectives of scenarios in crisis situations. A set of actions, which is defined in the modeling process, provides many options for development of the situation. It is also determined by various ways and means to achieve this goal in a dynamically changing conditions of existence. The main components of the model are the objects that characterize the organizational structure and the factors influencing them. Rules and restrictions that form the domain of the specific behaviors of the organizational structure and the external environment, are also components of the model. The components characterizing the result of modeling the behavior of the organizational structure, objectives and criteria are their achievement. The paper presents the structure and mechanisms of formation properties of the base object, on which are formed various types of facilities involved in the modeling process. A part of the rules on the nature of their activities and use in the simulation. The structure and mechanisms of formation properties of the base object used to implement flexible modeling algorithms. Algorithms should take into account the peculiarities of consideration of the organizational structure of management tasks in conditions of instability, multifactorial effects and dynamically changing rules and constraints on resources and allowed actions.
