Water-adsorption and desorption processes in the modified functional elements based on humidity-sensitive MgO-Al2O3 ceramics for microelectronics were studied using specialized positron annihilation lifetime system. It is shown that adsorption of water leads to transformation of positron annihilation spectra in the MgO-Al2O3 ceramics and reflects increasing of positron trapping near grain boundaries...
The main problem considered in the article is the appearance of interferences in the information formed by increasing number of users of computer tech, high volume circulation of information, increasing value of digital information and increasing threats. The goal is to find anti-interference code that would be simple in construction and would have interference stability parameters not worse that...
The work presents the results of modifications of the existing algorithm for localizing the quadrics' intersection points in ARM microcontrollers' firmware. The combination of the original algorithm and two its modifications allows to reduce the irrelevance of the regions with potential intersection points.
The work presents the results of comparison of tools for implementing an algorithm for calculation of the shortest path in a graph in mobile applications. We've revealed the amount of nodes starting from which Dijkstra's algorithm implementation in Java fails or at best becomes inferior to SQL implementation of the same algorithm. The results of the performed investigations come in useful for managers...
This work shows a problem of updating firmware, in particular its GUI and states the need of developing a PC application for translating GUI code written in different languages to C code that uses emWin. Design of such an application-“translator” is given.
This work presents an algorithm for roots separation of polynomial function intended for using with library functions that refine roots when their interval are correctly defined. Reusable function for root separation is developed and verified for ARM-based microcontrollers and can be useful as a part of embedded software for intelligent sensors that assume solving optimization problems.
The temperature sensitive thick-film structures in different design of sensitive layers and separate temperature and humidity sensitive thick-film systems based on spinel-type NiMn2O4-CuMn2O4-MnCo2O4 manganites with p- and p+-types of electrical conductivity and insulating magnesium aluminate MgAl2O4 were prepared. Taking into account good properties of obtained elements, they can be applied for microelectronics...
The work considers principles of design and a block diagram of a noise-immune signal transducer of galvanomagnetic smart sensor devices included those based on Hall sensors.
Applications of the combinatorial configurations as mathematical models for innovative design of logistic control processes, is known, provide improving the quality indices of the processes with respect to functional flexibility and control operation. The idea of these methods to the improvement of logistic processes is design based on so-called Ideal Ring Bundles (IRB)s — a kind of combinatorial...
The work presents an approach to modeling splitted Hall structures using software FEMLAB and MATLAB. The main advantage of the proposed approach is an opportunity of creating models on basis of the explicitly defined equations governing SHS exactly and taking proper account of Hall effect and magnetoresistance effect.
Application of the Perfect Combinatorial Sequences Theory, namely the concept of Ideal Ring Bundles (IRBs), for improving the quality indices of engineering devices or systems based on combinatorial technique is proposed in the paper. For example, resolving ability of radar is known to be of very dependent from positioning of elements in antenna array; high-performance technology of information coding...
Analysed receptions and algorithms of introduction of information in graphic files due to the use of bits with minimum meaningfulness on the basis of pseudonoise codes which can be successfully used for the concealment of any types of files in the case of containers with graphic information.
