TECHNOLOGY OF ENERGY SAVING SOY HARVESTING

Posted in 2017, ENGINEERING, Issue № 6(60) June 2017 | 0 comments

The high content of complete vegetable protein and oil in grains and chaff makes soy the irreplaceable culture of a particular importance, both in animal farming and in food industry. Based on the comparative analysis of the nutrients and mineral elements in straw and grain of crops and soybeans, the authors show the rationality of chaff collecting and use of a straw in animal feeding as an organic fertilizer. The results are given on the yield of grain from one hectare, the yield of chaff, the ratio of the fractional composition and the bulk mass of chaff. The technologies of energy saving harvesting of chaff have been developed to use chaff as cattle fodder. The introduction of the developed devices will ensure the collection of enough chaff for animal farming and increase the efficiency of animal farming by 11.62%, and milk yield by 14.39%. The efficiency of soy harvesting technology with harvesting of chaff, chopping and spreading of straw in prices of 2012 costs 1.2 million rubles per one harvester.

IMITATIONAL MATHEMATICAL MODEL OF REGISTRATION AND CONTROL OF HIGHLY DYNAMIC PROCESSES WITH LAB VIEW SOFTWARE

Posted in 2017, ENGINEERING, Issue № 5(59) May 2017 | 0 comments

The paper is devoted to the problems of measure and control of highly dynamic processes and how to solve the problem. The author proposes the algorithm for construction of a new calibration curve, it most fully reflects the behavior of a highly dynamic process, which in turn improves the accuracy of the information-measuring system. The model of the information-measuring system for measure and control of high-dynamic processes, developed in the graphical programming software Lab View is developed as well.

МЕТОД ВСТРАИВАНИЯ СТЕГАНОГРАФИЧЕСКИХ ВОДЯНЫХ ЗНАКОВ В ВЕЙВЛЕТ-КОЭФФИЦИЕНТЫ АУДИО-СПЕКТРОГРАММЫ

Posted in 2017, ENGINEERING, Issue № 4(58) April 2017 | 0 comments

Ставится проблема защиты авторского права аудиоданных. Рассмотрены устаревшие и современные методы защиты аудио-информации посредством стеганографических водяных знаков. На основе оценки их актуальности и эффективности выбран и проанализирован метод основанный на дискретном-вейвлет преобразовании. Основное преимущество метода заключается в его устойчивости к сжатию с потерями. На основе анализа предложен метод встраивания СВЗ в вейвлет коэффициенты аудио-спектрограммы. Для этих целей используется система математического моделирования MATLAB.

COMPARATIVE ANALYSIS OF THE NEURAL NETWORKS BASED ON PERCEPTRON AND LINEAR NEURAL NETWORKS IMPLEMENTATION RESULTS IN MATLAB FOR DETECTING INTRUDERS IN INFORMATION SYSTEM

Posted in 2017, ENGINEERING, Issue № 4(58) April 2017 | 0 comments

Mathematical model of the intruder detection system is developed. Data needed for training and implementation of a neural network was studied. The results of training and implementation of neural networks based on perceptron and linear neural networks in MATLAB for recognizing intruder presence in information system. The probability of type I and type II errors of intruder detection method based on the perceptron was calculated. The standard deviation for the analyzed types of neural networks was defined. The results showed that the neural network based on perceptron is able to determine intruder in the system more precisely.

EVALUATION OF LOADING WORKING BODIES OF A COMBINE HARVESTER WITH BREAD MASS

Posted in 2017, ENGINEERING, Issue № 4(58) April 2017 | 0 comments

It is proposed to evaluate the loading of the working body of a combine harvester with the help of a variation coefficient and the form of grain loss distribution along the width of the threshed roll. We developed a rapid method for determining grain loss at a combine harvester and original measuring tools to conduct field experiments. At an allowable level of grain loss behind the hammer mill (1.5%) of a combine harvester RSM-101 “Vector-410,” the variation coefficient in the distribution of winter wheat grain loss behind threshed rolls is 35.8% and that of barley 39.0%. The form of grain loss distribution along the width of the threshed roll shows that the maximum amount of bread mass passes in the central zones of the working body of the thresher.

OPERATIONAL EVALUATION OF ORGANIZATIONAL AND TECHNOLOGICAL RELIABILITY OF CONSTRUCTION PROJECTS

Posted in 2017, ENGINEERING, Issue № 4(58) April 2017 | 0 comments

The paper presents the results of the study of organizational and technological reliability (OTR) of large projects on capital construction. The definition of organizational and technological reliability is given, as well as the estimation of OTR in terms of time and cost of realization of the construction object. The dependence of OTR on negative impact factors is shown in the paper. The methodology of the operational evaluation of the organizational and technological reliability of capital construction objects is developed, the recommendations for interpreting the calculation results are given as well.
