Artificial neural networks on the base of neural-like computational units have many applications and are intensively used for solving numerous important practical tasks. It is common that the threshold unit is incapable solving many rather easy recognition tasks. The using of neurons with more complicated activation functions allowed surmounting this constrain. Although there were multi-threshold...
The article presents application of intelligent diagnostic system (IDS) for metal constructions protection from corrosion. IDS operation is based on the correct allocation of available resources on actions for achieve maximum efficiency. An example functioning intelligent diagnostic system was shown that can be used in a pipeline modernization in order to maximize its lifetime.
SQUIDy, czyli nadprzewodzące interferometry kwantowe (ang. Superconducting QUantum Interference Devices), stanowią najbardziej czułe znane aktualnie czujniki pola magnetycznego. Ze względu na możliwość pomiaru niezwykle małych wartości indukcji magnetycznej wykorzystywane są między innymi w pomiarach biomagnetyzmu. W artykule przedstawiono możliwość aplikacji oraz metody pomiarów magnetycznych przy...
In the paper a new method of fuzzy clusterization for high dimensionality data is presented. The method is based on algorithm reduction of large samplings to samplings with significantly smaller volume without loss of any essential clustering information.
Schemat ideowy układu elektronicznego jest zbiorem wzajemnie ze sobą połączonych elementów elektronicznych tworzących pewną sieć. Sieć ta jest strukturą, która może być w automatyczny sposób odczytywana analizowana. Automatyczna weryfikacja formalna schematu ideowego ma na celu wykrycie nietrywialnych błędów popełnionych przez projektanta w trakcie opracowywania schematu ideowego. W ramach analizy...
The increase of the functional possibilities of neural elements is important in the synthesis of neural network schemes that are used to implement complex mappings that arise in various problems of classification, form/pattern recognition, time lines prognostication, etc. This article introduces the concept of generalized neural element with the threshold activation function.
W artykule rozważono wykorzystanie technik symulacji komputerowej na potrzeby badania zjawisk związanych z ewolucją języków naturalnych. W stworzonym systemie symulacyjnym udało się odwzorować zjawiska związane ze spontanicznym powstawaniem nowych języków poprzez ewolucje języków już istniejących. Opracowany model uwzględnia także powszechnie występujące w świecie języków zjawisko systematycznego...
W artykule przedstawiono krótki przegląd znanych technik i obwodów ograniczników mocy sygnału mikrofalowego w porównaniu do nowych technik wykorzystujących efekt samoograniczania w obwodach z tranzystorami FET oraz nieliniowe obwody rezonansowe. Zaprezentowano teorię działania oraz wyniki pomiarów nowoopracowanych układów.

Various obstacles in this area are researched. Impossibility of ordinary approaches to identification system synthesis is shown. Requirements for new criterion are considered. Bases on these requirements...
One of the important ways of controlling aerodynamic flow near the surface there is an impact to the flow of pulsating plasma. For a real discharge devices used in such problems it is very important to understand what modes maintain plasma of atmospheric pressure give maximum effect with minimum energy consumption. In the applied aspect of this work presents the results of the development of a scalable...
Raster images obtained with the help of any biomedical equipment used for visual and automated analysis in medicine and biology may be called biomedical images (BMI). An important problem in the analysis of BMI is to identify and explore diagnostic features used for diagnosis. The informative feature in this process is the contour function of the BMI, which shows information about the change of state...
The unique approach to solving the problem of choosing experts groups in the system information-analytical research based on the use of induetive modeling paradigm to solving the cluster analysis tasks is proposed. This approach can also been used in many fields of applied researches pertaining to the problems of structuring, classification, clustering and modeling of complex systems.

This regards to the probability of successful transmission of information between transmitting and receiving nodes using the "Hot Potato" protocol.
In this paper the frequency terahertz detectors based on isotropic stratified structures are offered. In spite of the extreme simplicity of implementation, such devices are still not described in the literature and these are not manufactured by the telecommunications companies. The feasibility of creating such devices based on simple plane-parallel structures are shown. In this paper the function...
The article presents solving a problem of automation of partitioning of the original sample to the training and test samples to create diagnostic and recognizing models by precedents. We propose a new method of training and test sample forming. It preserves in a generated sub-sample the most important topological properties of the original sample and did not even needs to load of the original sample...
