This paper is concerned with building a rule base in the metod based on genetic fuzzy systems to control robotised manufacturing systems. The suggested method of building a rule base employs a ...genetic algorithm, or more pricisely, a chromosome coding algorithm. Widely used methods of chromosome coding have their faults, which make it necessary for the methods to extend their block diagrams of the genetic althorithm or make the methods labour intensive. The method, which is a compilation of well-known metchods, allows to use their advantages and eliminate the influence of their disadvantages. Therefore, it will be possible to efficently employ genetic fuzzy logic to automatically build a rule base of fuzzy logic.
W pracy prowadzono analizę budowania bazy reguł w metodzie genetycznego wnioskowania rozmytego w zastosowaniu do sterowania pracą zrobotyzowanych systemów wytwarzania. Opracowano metodykę budowy bazy reguł z użyciem algorytmu genetycznego - algorytm kodowania chromosomu. Stosowane w praktyce metody kodowania chromosomu obarczone są wadami. Powodują one konieczność rozbudowy schematu blokowego algorytmu genetycznego. Wiążą się także ze znaczną pracochłonnością. Zaproponowano metodę będącą kompilacją dotychczas stosowanych metod i pozwalającą na zachowanie ich zalet, a jednocześnie niwelującą oddziaływanie ich wad. Umożliwia więc sprawne wykorzystanie genetycznego wnioskowania rozmytego do automatycznej budowy baz reguł wnioskowania rozmytego.
Severe chronic diarrhoea secondary to enterocolitis is a severe complication of Hirschsprung's disease (HSCR). Persistent outlet obstruction, immunologic issues, and mucin/mucous imbalance can ...cooperate in the development of this complication. Furthermore, isolated reports described severe postoperative chronic diarrhoea mimicking enterocolitis in patients with sucrase–isomaltase deficiency, inflammatory bowel disease (IBD), or intestinal microvillus atrophy. This paper is aimed in describing three patients from our HSCR series who experienced severe chronic postoperative diarrhoea secondary to such uncommon associated anomalies: sucrase–isomaltase deficiency (one patient) and IBD (two patients). With an appropriate sucrose-free diet or immunosuppressive therapy these patients improved dramatically and their diarrhoea settled. These associated anomalies can be diagnosed with digestive endoscopies (both gastro-duodenoscopy and colonoscopy). Therefore, we developed a diagnostic and therapeutic algorithm for patients with chronic diarrhoea after a pull-through, which includes digestive endoscopy to be performed in selected cases.
The paper describes an application for visualization of four-dimensional graphs of a complex variable function. This application allowed us to construct an exact geometric algorithm for finding the ...real and complex roots of a polynomial on the same plane. A graph of an n-th order polynomial on the real plane allows us to define geometrically all the real roots. Number of real roots varies from 0 to n. The rest of the roots are complex and not determined by the graph. In the article, in addition to the graph of the basic polynomial, two auxiliary graphs are constructed, which allow us to represent all complex roots on the same real plane. Realization of this method is considered in detail for the solution of a cubic polynomial. In this case the method has exceptional features in comparison with polynomials of other degrees. We also propose an algorithm for constructing auxiliary functions for the general case of a polynomial of order n which have exact formulas for polynomials with order n ≤ 10. The algorithm for the first time builds the exact hodograph of poles for the control systems with feedback. We generalize the concepts of stationary and extremal points to the case of a complex function. The absence of the possibility of comparing the complex values of the objective function is compensated by an analysis of the behavior of the stationary point under small perturbations of the polynomial by linear functions. Optimality criteria are proposed using complex trajectories of stationary points.
In this paper, I define "shape element" just like a element of naural language. I propose a processing how to discover the architectural shape element based on conceptual KDD. That processing have ...some steps. Those steps are plan selection, making pre-data, using bipolar-scopically converting method, discovering algorythm of architectural shape element, interpretation/evaluation. There for, I explain about how to make the pre-data, about bipolar-scopically converting method, about how to discover the wall element. For get reliability to discovering algorythm, I verify by using conceptual N-gram. N-gram is used at study of natura language analysis. I verified as comparing with "static" and "dynamic". I propose a expression for calicuration perprexity. It is value of decision difficulity. perplexity=summation the AND area of N-area/summation all N-area I verified that perplexity by using 8 houses designed by Marcel Breuer. I got a result that "dynamic" is better than "static". I got good result from case study. I'll think the algorithm is to need to add script somewhat case of wall gathering status.
Queue dynamical scheduling algorithms are proposed for network switches supporting Quality of Service and making fewer jitter values spread while forwarding different QoS classes traffic and reaching ...more comfortable conditions for traffic transferring in case of misbalancing of granted for Classes of Service bandwidth. This is by means of continuous data transferring time restriction while each queue handled and of mixing different QoS traffic head frames which makes self-similarity less. Proposed algorithms are based on Deficit Round Robin (DRR) algorithm with chosen queue continuous handling session division onto a set of sub-sessions by means of periodical transmitting of special delimiting frame that is either the oldest frame from non-empty queues or chosen from random non-empty queue head frame or from the queue with the following pruning value. Sizes of transmitted delimitation frames are accounted for set deficits of respective queues. Proposed algorithms efficiency is asserted toward known algorithms, i.e. cyclic, stochastic, time selection algorithm, which is by means of simulation modeling of the algorithms and hierarchical colored Petri nets apparatus usage and means of CPN Tools packet. As criteria it is considered the values of variation of maximum and average values of traffic jitter for various Classes of Service.

In this paper we proposed multi-stage algorithm of small wind turbine power plant control when it supports maximum extracted power independently on traditional tip speed ratio using the wind speed. ...We made measurements of wind turbine parameters on urban and prairie territories, showed the necessity of power controlling the turbine, and vindicated the efficiency of control of small wind turbines in urban regions. We also formulated the conditions and structure of microprocessor operation, described the algorithm of wind turbine power control showing the possible situations and states. Each state is described with the corresponding microcontroller response and activity. We showed the advantages of pulse width modulation (PWM) is converting the electric values.
The purpose of article is to develop the transmission efficiency of various monitoring data in the wireless network with limited operating bandwidth. They are based on the implementation of the ...processor means running complex algorithms for adaptive filtering and compression of the signals, operational data compression without any loss, encryption of data transmission compact and secure information packets through noisy radio channels. As processor performance and speed running means are limited, therefore the characteristic feature of rapid coding algorithms and packet data monitoring tools set is their optimization for speed and accuracy from data encryption point of view. Because of their implementation the outgoing information package and the transmission or retransmission duration of packets with the effects of channel noise wireless network are significantly reduced.

We consider the problem of building a Trailer Backup Assist System that would function in conditions of a priori uncertainty about the parameters of the system itself and the external disturbances. ...External uncontrolled disturbances can arise from non-horizontal surfaces, the existence of significant road irregularities, variable density of soil, etc. Mathematical model of controlled trailer is justified; from this, adaptive control law is generated for movement according to the steering wheels deflection, to achieve a predetermined hitch angle. The a priori uncertainty is eliminated by means of the current parametric identification of the controlled object mathematical model, while current estimates are used directly for control law synthesis. For the formalization of system requirements, an implicit reference model is used. Justification of adaptive control system operation is built on the simplified adaptability conditions. A model example is given.
