MATHEMATICAL EQUATIONS ANALYSIS OF ACOUSTIC AND ELECTROMAGNETIC FIELDS ARE CREATED BY ACOUSTIC MAGNETIC DEVICE AND DETERMINATION OF SIMILARITY CRITERIA FOR THE CREATION OF NEW CONSTRUCTIONS OF ACOUSTIC MAGNETIC DEVICES DESIGNED FOR USE IN HYDROPONIC SYSTEMS

abstract 1171603031 issue 117 pp. 500 – 527 31.03.2016 ru 304
Conditions in which the work of acoustic magnetic device proceeds are complicated because of the number of interconnections. Solving problems under such conditions analytically is difficult because of many variables and complexity of some dependencies. The article describes the conditions in which the work of acoustic magnetic device, designed for nonchemical treatment of hydroponic solution, takes place. The criteria, establishing the initial state of the chains, containing mutual inductance, are analyzed. The work establishes the criteria relating the physical parameters of the environment with the output parameters of the device. The similarity of conditions of heat transfer on the surface of the device is provided, and the relation of the scale of temperature and power lost when heating the ferrite and winding machine is determined. The criterion of the heat transfer process is defined. The criterion, determining the relation of the environment temperature to the thermal mode of the acoustic magnetic device, is defined. The criterion of the conditions at the boundaries of the system and cavitating liquid is determined. It is found, that the cavitation area appears in the technological volume of liquid at the work of acoustic magnetic device. The criterial equation for geometric parameters of different types and constructions of the acoustic magnetic device is defined. In accordance with the task based on the third theorem of similarity, the group of criteria that provides the similarity of the model to the proposed original by all existing indicators, is selected

MODELING COMPLEX MULTIFACTOR NONLINEAR CONTROL OBJECTS BASED ON A FRAGMENTED NOISY EMPIRICAL HIGH-DIMENSIONAL DATA IN A SYSTEM COGNITIVE ANALYSIS AND IN THE INTELLECTUAL EIDOS-X++ SYSTEM

abstract 0911307012 issue 91 pp. 167 – 191 30.09.2013 ru 1328
In the article, we have considered the application of a system-cognitive analysis and the Eidos-X++ intellec-tual system to create complex multifactor models of nonlinear control objects on the basis of noisy frag-mented empirical data of large dimension and for the use of these models to solve problems of forecasting, executive decision making and research of the model objects. We have formulated the systematic generalization of the principle of Ashby (for nonlinear systems). The numerical example of a study of an abstract nonlinear system (Lissajous figures), in which the combined effect of multiple factors is the sum of the influences of each of these factors separately, that says about non-compliance of these factors, the principle of superposition and nonlinear effects in the system under consideration. It is shown, that the proposed device and software tools allow us to model such systems. We note, that the proposed device and instrumentation allow to interpret some classification scale, as projected geographical coordinates of the event, and others, like the foreseeable events and their severity, which allows you to get cartographic visualization of recognition of the place and time of events

THE DECISION OF THE GENERALIZED PROBLEM OF APPOINTMENTS IN SYSTEMIC-COGNITIVE ANALYSIS

abstract 0510907004 issue 51 pp. 83 – 108 28.09.2009 ru 2225
In the article the problem about appointments (backpacks) in various and more general statements is shortly examined: 1) the size of cargoes and volumes of backpacks; 2) the various utility of cargoes depending only from cargoes, but identical to all backpacks, and various expenses for their placing, and also restrictions on the resources, connected with backpacks, spent for cargoes at their placing; 3) various utility of each cargo for different backpacks, various expenses for placing of cargoes and various resources of owners of backpacks. The technology and an application technique of systemic-cognitive analysis and its toolkit - the "Eidoses" system for the solution of generalization of non-meeting in the literature before problem of the appointments, providing automatic forecasting of degree of utility of cargoes for different backpacks on the basis of signs of cargoes by the decision of a problem of recognition with application of the model based on base of precedents

THE RESULTS OF EXPERIMENTAL RESEARCH OF INFLUENCE OF ACOUSTIC AND MAGNETIC FIELD ON ELECTROCONDUCTIVITY AND PH VALUE OF HYDROPONIC SOLUTION

abstract 1101506035 issue 110 pp. 519 – 531 30.06.2015 ru 1219
The article deals with the results of research of acoustic and magnetic field influence on conductivity and pH value of hydroponic solution. For carrying out researches in this area the hypothesis of possibility of nutrient solution influence on ions by means of an acoustic and magnetic field is set up. A laboratory scale plant was constructed for a pilot study of the hypothesis. The solution was moved in the tube passing through a ferrite ring with winding. Thus, the solution was exposed to the influence of acoustic and magnetic field. The object of research was hydroponic solution of (NH4)2SO4; (NH4)2HPO4; K2SO4; Ca(NO3)2; MgSO4 in water having adjusted concentration and acidity. The solution was taken from the tank of laboratory scale plant by means of the pump, passed through the working area of the acoustic and magnetic device, filter, and then was poured into the tank, from which the sample for pH level changing was taken. The pH value was measured at the temperature of 22С by using electronic pH-meter KL-009(1)A. For control of instrument readings acidity was tested by universal test-paper. The initial pH value of solution made 5. As a result of acoustic and magnetic treatment of solution pH value of hydroponic solution increased from 6 to 6.9. The results show the possibility of pH value correction by small energy input

СSC-ANALYSIS AS THE ADEQUATE IN-STRUMENT OF CONTROLLING AND MAN-AGEMENT FOR MEDIAL AND SMALL FIRM

abstract 0631009002 issue 63 pp. 24 – 55 27.11.2010 ru 2073
In the article, it is demonstrated that for the present stage of evolution of controlling its increasing infiltration into averages and small firms is typical. Thus, there is a problem to discover uniform, simple in assimilation and the inexpensive toolkit of the control unit-ensuring making of intellectual procedures for management on various hierarchy levels of control of company. Demands to control unit tooling are justified; it is demonstrated that to the formulated demands there matches a method of the computerized system-cognitive analysis and its tooling – "Eidos"system. Instances of application of the yielded tooling for the problem of quality management of preparation of specialists, information security, determination of the nomenclature and volume of the implementable goods, a basic technology and staff management selection are shown
