In order to perform this task automatically on a large scale, aerial photos provide a useful solution. The goal of this research project is the development o...

The role-oriented concept of programming is becoming more common in recent times. Expanding the traditional object-oriented paradigm, it allows us to apply a more flexible approach to the development of the information system and simplify the task of the developer. The use of role-oriented structures in modern applications raises the question of storing them in a database. The task of extracting homogeneous semantic entities from structured documents has a high potential for solving with the use of roles or their ...

The amelioration fund of Ukraine is 5.4 million hectares. Significant areas of these lands are used by special drainage-modular systems with vertical and horizontal drainage. Such drainage is a system of vertical or horizontal fluid drain storage, located in a parallel way. These systems can be used to inject micro- and nanoparticles of sorbent or as filter-traps for already used sorbent particles. Therefore, a fundamental understanding of the processes of mass transfer in a saturated porous medium in the presence...

Methods of deductive inference that are various modifications of the principle of resolutions are quite effective in logic. The results and justifications for the fuzzy conclusion of the resolution type are widespread in the predicate calculus. The existing models of the resolution inference are effective, and also quite simple and convenient, for conventional reasoning under incomplete information and for automatic processing of uncertain knowledge in interactive systems. However, in such models the set of genera...

The authors propose a model of nonlinear interaction of social network agents, which is based on a matrix generalization of the known one-dimensional logistic mapping. Similar models have not been considered previously and have not been investigated numerically. Despite the relative simplicity of the proposed non-linear model, in the course of numerical experiments, various modes of agent behavior were observed. Namely, one of the agents hesitated in making a certain decision, others were able to "agree" (came to ...

Central power stations have lower efficiency, high polluting stations affects the environment. In order to overcome these problems structural changes are needed i...

Long-term research on the ownership structure of individual farms in rural areas has shown that these areas are characterized by a defective patchwork of private land ownership. The sizes of the patchwork may limit, and often even prevent, the programming of works on agricultural land. The development of an algorithm for identifying areas characterized by a strong concentration of a defective patchwork of land ownership allows the selection of these areas (groups of villages) where land replacement works should be...

The federal information system for providing state final certification and admission can be transformed from a tool of adherence to and compliance with the law in the sphere of admission to higher education programs as the basis for an automated information system for organizing a centralized competitive selection for Russian universities. The research shows that this system needs only a small modification in terms of expanding the list of stored information. At the same time, the technical capacity of the federal...

Rail transport along specially important objects such as bridges and tunnels is of particular importance. In addition to their importance it also represents a very high-risk hazard, on the grounds that it contains a very weighted load and peoples within this transportation.

Most of bilingual or multilingual dictionaries, especially the printed ones can be represented as a simple relational database with two relations with cardinality 1:N for each side of the dictionary. This database structure is actually sufficient if the user needs only word to word translation and if they are experienced enough to choose a proper translation from mostly many synonyms. One step forward is a contextual dictionary. The translation is influenced by the context of the word, what can make the translatio...

Systematic research on the collective behaviour of formal grammars started in the 90s of 20th century. One of the variants of grammar system models was inspired by eco-systems and it is called eco-grammar systems. Eco-grammar systems describe the interplay between an evolving environment and the community of agents which form the eco-system. Each agent as well as the environment of the eco-grammar system is represented by its own 0L scheme. Agent in the eco-grammar systems can change environmental symbols independ...

Positioning is a critical task for applications that involve mobile nodes as well as applications that rely on fixed nodes. The Global Positioning System (GPS) is a satellite-based navigation system that provides its users with proper equipment access to positioning information. The Iterative Least Squares (ILS) and Extended Kalman Filtering (EKF) techniques are two of the most commonly used approaches for GPS positioning. Both ILS and EKF techniques are based on the same pseudorange equation and both of the techn...

Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a modulation technique used to encode a message into a pulsing signal. Although this modulation technique can be used to encode information for transmission, its main use is to allow the control of the power supplied to electrical devices.

The gamma-ray logging method is one of the mandatory well logging methods for geophysical exploration of wells. However, during the conduct of such a study, the sensor, for one reason or another, may stop recording observations in the well. If a small number of values are missing, you can restore these values using standard methods to fill in gaps like in time series. If data miss a large number of values, observations usually are made again, which leads to additional financial costs. This work proposes an alterna...

Scientific codes are usually highly parallelised and executed on heterogeneous architectures. Nowadays, it is common to use graphics accelerators (GPUs) to speed up data-parallel algorithms, and in the meantime, the already existing CPUs can help in this work. Distributing the jobs between systems is always a difficult problem, especially when the processing units have different runtime environments and hardware architectures. There are several attempts for static and dynamic load balancing, but most of these are ...

The evacuation time of occupants in a fire event is a particularly important parameter, both for the development of emergency evacuation plans and in the post-event investigation. To estimate this time, the classic approach uses alarm / evacuation trials. These simulations involve the allocation of human and financial resources and have the disadvantage of not being able to cover a wide range of technically possible critical scenarios. Moreover, it has been shown that in real fire cases, human behaviour can be sig...

Wood was the most common source of energy on earth, being gradually replaced by fossil fuels. Given that the wood used in the generating stations comes from properly managed forests, then the carbon emitted from the chimneys can be annihilated by the carbon that is absorbed and used by the freshly planted trees. Wood can therefore be considered as carbon neutral. It remains to be seen if this theory is actually verified. Once it was decided to classify wood as a renewable source, its consumption increased exponent...

In information technologies classical rules of regulation are often used for designing systems of automated control of technological objects. Application of these rules requires access to the aprioristic information on the object of control. One of the main causes for the development of new approaches is a lack of aprioristic information on the studied object which is adequately described by a representative class of nonlinear dynamic models perfectly demonstrating the most significant and important properties of ...
