Opis:: Pojęcie potencjału wywodzi się z fizyki, jednak ma zastosowanie także w naukach ekonomicznych. W ekonomii, ekonometrii przestrzennej, rozważa się, między innymi, potencjał ludności, dochodu, analizuje się intensywność oddziaływania jednostek terytorialnych danego systemu na siebie nawzajem. Wartość potencjału zależy od elementów macierzy odległości pomiędzy jednostkami. Celem artykułu jest pokazanie sposobu obliczania potencjału ekonomicznego jednostek terytorialnych oraz zastosowanie analizowanej metodyki do pomiaru potencjału ekonomicznego organizacji. Artykuł składa się z dwóch części zasadniczych; w pierwszej omówiono metodykę badań, druga część zawiera wyniki analiz empirycznych.
The idea of potential derives from physics, however, it is also applied in economic sciences. In economics, spatial econometrics, among others, considered is the population's potential, income potential and analyzed is the intensity of mutual influence of territorial units of a given system. The value of the potential is dependent on the matrix of the distance between units. The aim of the article is to present the way of calculating the economic potential of territorial units as well as the application of the analyzed methodology in the measurement of economic potential of organizations. The article consists of two basic parts; the first one discusses research methodology, the second part includes the results of empirical analyses.

Opis:: Plants are subject to stimuli from the environment on which they strongly depend and in contrast to animals, they are unable to escape harmful influences. Therefore, being able to receive stimuli they have developed adequate responses to them. Such a reaction can occur in the area of a stimulus action or cover the whole plant or its parts. In the latter case, it is a systemic reaction. The plant reaction is expressed by various intensity, rate and kind of response. It is interesting to know the character of the signal informing about a stimulus, the routes of its propagation and the transmission mechanism. Three conceptions of excitation are distinguished: 1) propagation of chemical agents formed at the site of a stimulus action with the flow of the phloem sap or through the atmosphere (in the case of volatile substances) to other plant parts, 2) a very fast transmission by the xylem in the wave of hydraulic pressure formed after a plant damage. From combining the "hydraulic" and "chemical" hypothesis a conception of hydraulic dispersion has been formulated which assumes that chemical substances synthetized after an injury can be transferred very fast with the wave of hydraulic pressure changes in the whole plant, 3) a stimulus evokes the action potential (AP), and its transmission along the whole plant, plant organ or specialized tissue, by local circuits from cell to cell. Strong, damaging stimuli can evoke variation potentials (VPs), the character of which differs from APs. It is postulated that transmission of VP occurs by a hydraulic dispersion and electrical changes seem to be secondary phenomena.

Opis:: Artificial potential fields (APFs) are a popular method of planning and controlling the path of robot movement, including unmanned aerial vehicles (UAVs). However, in the case of nonholonomic robots such as fixed-wing UAVs, the distribution of velocity vectors should be adapted to their limited manoeuvrability to ensure stable and precise position tracking. The previously proposed local asymmetrical potential field resolves this issue, but it is not effective in the case of windy environments, where the UAV is unable to maintain the desired position and drifts due to the wind drift effect. This is reflected in the growth of position error, which, similar to the steady-state error in the best case, is constant. To compensate for it, the asymmetrical potential field approach is modified by extending definitions of potential function gradient and velocity vector field (VVF) with elements based on the integral of position tracking error. In the case of wind drift, the value of this integral increases over time, and lengths and orientations of velocity vectors will also be changed. The work proves that redefining gradient and velocity vector as a function of position tracking error integrals allows for minimisation of the position tracking error caused by wind drift.

Opis:: This work is a continuation of the problems of kinetics, dynamics, and energy of solid on the example of a tool fixed flexibly under cutting. The work consists with three parts. Part 1 covered the kinetics of the system. Present work is devoted to the dynamics of a tool in the machining space-time. Dynamic characteristics of the whole machining system are considered by determining forces being the measures of particular reasons for material cutting. The reasons are the following forces: gravity, inertia, and repel. In the last Part 3 of the work, a special attention is to be paid to the work description and the energy notion.

Opis:: The relevance of the research subject is related to the fact that exports are an integral part of the overall economic potential of any state and largely determine the pace of its economic development. The slowing of export growth relates to exports to the EU countries in recent years; the negative trade balance of Latvia with these countries increases the need to analyse the factors affecting the realisation of export potential and to search for opportunities to do so. The purpose of this study is to analyse the export potential of Latvia to the EU countries, categorised by groups of goods. To achieve the goal of the study, it was necessary to determine the essence of the export potential, identify factors that affect the implementation of the country’s export potential and assess the export potential of trade between Latvia and the EU countries by groups of goods. The study used quantitative and qualitative methods of analysis, statistical data analysis, as well as methods for assessing the potential of Latvian exports to the EU countries. As a result of the study, groups of goods with trade potential for export to the EU countries have been identified.

Opis:: The paper presents a new adequate look on the character of motion of any material body, such as moving vehicle. It has been proved, that motion of material bodies has a quantum character. Due to this their consecutive energetic states are obtained by a jump. The phenomenon of quantum in the reference to vehicle kinetics has been derived by indicating its place on the background of characteristics of whole mechanics. The length of vehicle way in particular phases of its motion is that source characteristics the derivatives of which form the development of motion description of a material solid/body. It has been indicated that the quantum nature of body motion does not depend on its magnitude. Thus, as has been noticed, there is an analogy between the macro-body motion and electron motion which change its energy also by jump, by getting from one orbit (energetic level) to another.

Opis:: In this paper, we have solved the spinless Salpeter equation (SSE) with Hellmann potential under the framework of NIkiforov-Uvarov (NU) method. The energy eigenvalues and corresponding wave functions for this system express in terms of the Jacobi polynomial are also obtained. With the help of approximation scheme the potential barrier has been evaluated. The results obtained in this work would have many applications in nuclear physics, chemical physics, atomic and molecular physics, molecular chemistry and other related areas as the results under limiting cases could be used to study the binding energy and interaction of some diatomic molecules. As a guide to interested readers, we have provided numerical data which discuss the energy spectra for this system.

Opis:: This work is a continuation of the problems of kinetics and dynamics of solid on the example of a tool fixed flexibly under cutting. Present work is concerned on the development of work and energy. A special attention has been paid to the work description by underlying a distinctness and lack of connection with the energy notion. Polarization of these two magnitudes has been revealed. An adequate and extended definition of energy in general, with mechanical energy in particular, is formulated. There are three kinds of mechanical energy considered, located on the stable static potential field being one of the limits of the machining space-time. They are the following energies: repel, inertial, and gravitational. Proper measures/potentials have been assigned to these energies, treating the energy as a mental notion, having no physical meaning in contrast to the potential as the physical magnitude.
