Very often, outputs provided by GIS functions and analysis are assumed as exact results. However, they are influenced by certain uncertainty which may affect the decisions based on those results. It is very complex and almost impossible to calculate that uncertainty using classical mathematical models because of very complex algorithms that are used in GIS analyses. In this paper we discuss an alternative method, i.e. the use of stochastic Monte Carlo simulations to estimate the uncertainty of flow accumulation. The case study area included the broader area of the Municipality of Cacak, where Monte Carlo stochastic simulations were applied in order to create one hundred possible outputs of flow accumulation. A statistical analysis was performed on the basis of these versions, and the "most likely' version of flow accumulation in association with its confidence bounds (standard deviation) was created. Further, this paper describes the most important phases in the process of estimating uncertainty, such as variogram modelling and chooses the right number of simulations. Finally, it makes suggestions on how to effectively use and discuss the results and their practical significance. [ABSTRACT FROM AUTHOR]

In this paper, we consider the algorithm for calculating the object dynamic characteristics in the automatic control system. Specifically, the algorithm allows obtaining numerically pulse and transitive characteristics of the process relying on the reaction of a control system on the task change. The algorithm of this problem solving can be numerically applied by employing the Duhamel integral. Moreover, we consider the sample of this algorithm program implementation when modeling transients in the control system. [ABSTRACT FROM AUTHOR]

In this paper, we utilize the Kalman's filtration algorithm for processing the real data obtained from the temperature control system. This data consists of a complex combination of various noises. We prove that the Kalman's filter satisfies the required filtration quality. Moreover, it can continuously process the data unlike traditional and previously used methods of programmatic filtration. Therefore, our method can be used by automatic control experts for data filtration of complex combination of noises in the field of heat power engineering. [ABSTRACT FROM AUTHOR]

The research described in this paper studies an adaptive algorithm for the control system for a one-dimensional dynamic object with an aperiodic constant-sign pulse response characteristic. Specifically, we present the conditions for obtaining the feedback ratio based on the indirect estimation of the resultant action and the controlled variable prediction. Our experimental results show that these conditions provide the guaranteed control accuracy under arbitrary disturbances. [ABSTRACT FROM AUTHOR]

Algorithms of synchronized pulsewidth modulation (PWM), based on special space-vector-based control scheme (with the use of minimal number of voltage space vectors), have been applied for synchronous control of four neutral-point-clamped (NPC) inverters feeding six-phase (dual three-phase) drive on the base of asymmetrical open-end windings induction motor. It allows providing continuous synchronization and symmetry of the phase voltage of system during the whole control range for any ratio of voltage magnitudes of DC-sources, and for any configuration of DC-sources. Therefore, in this case four inverters of the system can be supplied by reduced number of insulated DC-sources (by one, or by two, or by three DC-sources instead of four DC-sources for standard system topology based on four two-level inverters). MATLAB- based simulations show behaviour of the system at steady-state control modes. References 11, table 1, figures 6. [ABSTRACT FROM AUTHOR]

The article describes the information technology for recognition of the number on the hot metal transfer ladle. Processing stages have been identified and described: preliminary processing, localization and number identification. The filtration and incomplete thresholding by means of global binarization with an automatic choice of a threshold have been analyzed. Localization is executed by a single linkage (the nearest neighbour) method with the modified windowing search algorithm. After localization area has been identified, a segment is generated. Identification is accomplished by means of a unique method, which is based on an indistinct representation of images and their comparison with indistinct standards. Combining in a characteristic point the segment which is being analyzed with a prototype segment kernels are formed. Those are then fractured into blocks. Based on these blocks two fuzzy sets are obtained -- one for the segment that is being analyzed and one for the prototype. For these sets the relative Hamming distance is then calculated. The calculated value shows the degree of similarity of the segments. During the tests it was proved that the Hamming distance for the segments with identical numbers is 0,01÷0,16, whereas for the segments with numbers of different ladles it is 0,26÷0,49, which is enough for a successful identification of a ladle by the image of its number.
