Opis:: This article describes a new mathematical software usage model, which includes the effect of the set of global and external variables values for further analysis of multi-test scenarios to improve the effectiveness of the testing software. This model is represented as a graph of transitions and a set of variables with respective sets of equivalence classes. The proposed approach is particularly relevant for computational algorithms with complex logic.

Tematy:: predicate model

predicate algebra
algebraic structure
Opis:: The restriction of the input set in the form of a positive cone of the space is not always correct. For instance, while studying the organ of vision, people are limited not only to positive, but also to radiation with not very high energies, because excessively intense can disturb the visual organ. In this particular case, a convex body of a linear space is a fairly acceptable model of the set of input signals. Therefore, we consider linear predicates with this domain of definition.

Opis:: The intelligent decision making requires the consideration of current contextual information. The article is devoted to construction of formal models for the presentation and usage of contextual information for decision-making in the field of employment. The paper analyses existing approaches to the definition of the concept of context at the conceptual level. The results of comparison of formal context models taking into consideration the requirements for employment business processes are presented. The ontological approach is selected as a basis for contextual models specification. The paper presents the formal representation of the context models for business operations of the employment sector. The model of contextual graphs for the solution of the problem of employment business operations context refinement was developed.

Opis:: System analysis as scientific and engineering discipline underpins research and development in other areas. However, system analysis models and methods are often taught separately and, as a result, system analyst cannot form a holistic understanding of this area. In order to deepen our understanding of system analysis’ concepts and relations the ontology of this area was built. It was constructed based on models and methods of system analysis considered as knowledge patterns. The concept of system was selected as a central concept of ontology. Other important concepts, such as goal, function, decision and process are relating to it. Finally, the applications of created system analysis ontology for teaching system analysis in high school and as a part of semantic grid are discussed.

Opis:: This paper involves techniques for improving the quality indices of engineering devices or systems with non-uniform structure (e.g. arrays of sonar antenna arrays) with respect to performance reliability, transmission speed, resolving ability, and error protection, using novel designs based on combinatorial configurations such as classic cyclic difference sets and novel vector combinatorial configurations. These design techniques makes it possible to configure systems with fewer elements than at present, while maintaining or improving on the other operating characteristics of the system. Several factors are responsible for distinguish of the objects depending an implicit function of symmetry and non-symmetry interaction subject to the real space dimensionality. Considering the significance of circular symmetric field, while an asymmetric subfields of the field, further a better understanding of the role of geometric structure in the behaviour of system objects is developed. This study, therefore, aims to use the appropriate algebraic results and techniques for improving such quality indices as combinatorial varieties, precision, and resolving ability, using remarkable properties of circular symmetry and non-symmetry mutual penetration as an interconnection cyclic relationships, and interconvertible dimensionality models of optimal distributed systems. Paper contains some examples for the optimization relating to the optimal placement of structural elements in spatially or temporally distributed technological systems, to which these techniques can be applied, including applications to coded design of signals for communications and radar, positioning of elements in an antenna array, and development vector data coding design.

Opis:: It is widely known that during the post-harvest handling of a number of crops pneumatic separators are often used. It is proved that in order to improve separation process by using an air flow becomes possible through the use in the separation channels an electric field of corona discharge as additional working body. The electric field makes an additional force effect on the particles of the separated mixture. Since the seeds of cultivated plants and weeds belong to different species, their electrical properties interact with the working bodies of pneumatic separators in different ways that enables quality improvement of seed mixtures separation. We consider the ellipsoidal particles’ behaviour under the influence of gravity, electric power and air flow in pneumo-electric separator channel taking into account their bumping into the walls. We also worked out the differential equations that reflect the mathematical model of the particles under the totality of these forces. This model describes the movement of particles in the pneumo-electric separator channel and allows at any time to calculate the coordinates of trajectories. Based on their analysis we can explore the influence of the controlled process parameters on the pneumo-electric separation and determine their optimal parameters under which the separation of the investigated seed mixtures is the most effective and the components of which are of ellipsoid shape.
