Opis:
In the globalized world, the issue of establishing new forms of cooperation in Ukraine’s energy sector with the countries of Central Europe is becoming urgent. With this in mind, the prospects of the project of "vertical" economic integration from north to south, from Scandinavia and the Baltic to the Balkan countries with access to the Adriatic Sea have been considered. The project of the Baltic-Black Sea alliance that is made up on the basis of security motives and includes the development of energy cooperation has been analyzed. It has been proven that with its powerful energy potential, Ukraine is able to integrate into the energy space using its own resource base and diversify the supply of fuel and energy resources within the energy space on a competitive basis. The scientific concept of the polarized space for the region’s development with a resource potential for the development of Ukraine’s economy in the context of globalization and European integration has been proposed.

Opis:
The concept of beauty in the landscape of the city has become relative; the aura of the place, attractiveness, value to attract customers regardless of the time of the day and year became important. Not always the public space gives good energy to the recipient. Sometimes, contrary to the expectations of the originators of consumer offer for this space, it is even considered to be repulsive. The phenomenon of generating good or referred to as bad energy by urban public spaces existing in reality, is an interesting research topic. It can accommodate both the newly created public spaces, old, historic spaces currently being reformed and iconic space. The way to create new successfully cases of public spaces is relying on multidisciplinary studies of the sociology and psychology of architecture.

Opis:
The Borowski Theory of Gravitation (BTG) indicates that movements of mass such as planets through space are determined by differential pressures from dark matter. One of the consequences of the final epoch is that there would be no matter but only distance. Quantitative solutions indicate that the tensor to set universal average dark matter pressure equal to G, the gravitational constant, would require that the terminal length would be ~2.2∙1069 m or effectively identical to current estimates of energy equivalence of the universal mass. For the earth’s orbit the force from the dark pressure is the same order of magnitude as the force associated with the product of the planet’s mass and background free oscillations whose origins are still ambiguous. The convergences of solutions suggest that the BTG may reveal alternative interpretations and mechanisms for the role of gravitation in planetary motion.

Opis:
Using functions from electrical networks (graphs with resistors assigned to edges), we prove existence (with explicit formulas) of a canonical Parseval frame in the energy Hilbert space [formula] of a prescribed infinite (or finite) network. Outside degenerate cases, our Parseval frame is not an orthonormal basis. We apply our frame to prove a number of explicit results: With our Parseval frame and related closable operators in [formula] we characterize the Priedrichs extension of the [formula]-graph Laplacian. We consider infinite connected network-graphs G = (V, E), V for vertices, and E for edges. To every conductance function c on the edges E of G, there is an associated pair [formula] where [formula] in an energy Hilbert space, and Δ (=Δc) is the c-graph Laplacian; both depending on the choice of conductance function c. When a conductance function is given, there is a current-induced orientation on the set of edges and an associated natural Parseval frame in [formula] consisting of dipoles. Now Δ is a well-defined semibounded Hermitian operator in both of the Hilbert [formula] and [formula]. It is known to automatically be essentially selfadjoint as an [formula]-operator, but generally not as an [formula] operator. Hence as an [formula] operator it has a Friedrichs extension. In this paper we offer two results for the Priedrichs extension: a characterization and a factorization. The latter is via [formula].

In the paper an identification of low speed diesel engine operation in direct propulsion plant equipped with fixed pitch propeller during ship manoeuvring. It was starting of engine and gathering speed of ship. Analysis of engine operation was based on changes of engine torque and time of ship bring up to speed. Operation of reciprocating internal combustion engine consists in converting the supplied fuel energy and delivering it to ship propeller. This condition implicates converting different amounts of energy in different time. The main attention was given to operation of engine caused by crank pin forces in wide range of revolutions and their influence on mechanical load of ship propulsion plant. The torque is the major component determining the engine load. As a matter of fact its mean value is low, but a passing torque can be four times higher than the rated torque. The second important component of propulsion engine operation is the time of ship acceleration from one speed to another. It determines dynamic properties of the ship describing its reductional feature. This time is determined in dependence on other parameters characterizing operation of ship propulsion plant and ship motion by means of dimensional analysis. These parameters were regarded as dimension quantities of three-dimensional space. Thus the three independent in dimension parameters can be noted in digital form in dimensional functions. The knowledge of operation parameters of ship propulsion plant and the knowledge of ship motion dynamics makes possible rational manoeuvring. It increases safety of ship motion and failure-free operation of ship propulsion engine. The proper operation of engine requires delivery to the propeller such amount of energy, which ensure the motion of ship with required speed in given sailing conditions.

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.

The work contains some of the elements of adequate quantum theory of impact phenomenon. These elements form the prelude to verification of the existent non-adequate theory of the impact phenomenon. At first a correct definition of impact has been formulated. For comparison, the interpretation of the elastic impact according to the existent knowledge is given. Then, taking advantage of the new correctly formulated the principle of mechanical energy conservation, the energetic states of impacting body have been described. Basing on this, the formula on dynamic deflection has been derived. This formula is adequate in character and fully corresponds with investigated reality.

Opis:
The following article presents the method of determining the ship 's propulsion engine operation basing on the engines work parameters by means of dimensional analysis. The operation of engine is considered as effective energy transfer to ship propeller in the form of work during its operation. According to Girtler engine operation can be considered as, a new physical quantity of dimension Joul multiplied by second [2, 3J. A random type of combustion in engine cylinders makes possible to deal with engine operation as a random variable vectors in the Hilbert space isomorphic with dimension space. The analysis of stochastic engine workprocess is alternatively used as a set of determinist time functions by means dimension analysis. Parametric functions of engine work were determined on the basis of algebraic analysis scheme designed by S. Drobot. This scheme makes possible to control the correctness of conclusion rules regarding mathematics in digital functions describing operation of ship propulsion engine. Additionally the parametric form of function makes possible to investigate the influence of function parameters on correctness of engine operation. It makes possible to forecast the engine operation i given sailing conditions and to estimate steerability of ship during the voyage. It improves the safety of ship operation propelled by single engine propulsion plant.

Opis:
The article presents identification methods of ship propeller torsional vibrations in dimensional space and ways for their dumping. Propeller torsional vibrations are caused by static, dynamic and hydrodynamic unbalance of propeller itself and its operation in non-uniform velocity field of ship hull. The propeller working in uneven velocity field of the hull creates cyclic thrust forces, peripheral vibrations of shaft as well as flexural and torsional load of propeller shaft. Vibrations cause additional thrust load on shaft bearings and shaft bending moment. Vibrations of ship hull, particularly its stern section cause variation of pressure field created by propeller. Amplitude of particular parts of the hull comes from the action of cyclic forces created by working ship propeller. They can be very large. Therefore, the ways to reduce vibrations caused by running propeller are very important. Given in the article methods of vibration dumping calculations conduct to determination of vibration dumping coefficients. Calculation results are comparable to measuring results in spite of fact they were determined under assumption of different velocity fields of water flowing through propeller circle. Amplitudes of vibrations depend on number of propeller blades and pulsate with the basic frequency equal to product of the rotational speed and number of blades. Causes of such vibrations and additional load of vessel stern are described in the article. An attention was paid to assure the greatest possible uniformity of velocity field by adequate design of stern shape and accessories. The ways to reduce torsional vibrations of propeller by the appropriate selection of blades number and their accurately machining are also given in the article.

Opis:
The space-time geometry around a photon was held constant despite the photon sources speed relative to a reflector, in a previous publication [1]. This resulted in the conservation of energy and momentum being balanced for a reflection, when motion of a reflector occurs after a reflection, relative to a reflector and a photon sources perspective, for the first time, to the author’s knowledge. As a result, photons from moving sources have energies that are not equal to the energies observed. As photon sources moving towards and away from a reflector reflects photons, there may be mechanisms where energy deficient photons and photons with excess energy, compared to what is observed, acquire energy and disperse energy from and to its surroundings, respectively, so a reflection can occur. A reflector can be in a solid, liquid or a gas, where each phase presents possible sources of energy, for energy deficient photons, and possible sinks for photons with excess energy. No discreet and non-discreet energies associated with the phases of matter are disregarded as a possible source or sink, as this may delay detection of energy deficient photons and photons with excess energy, where tests for their detection are suggested.

Opis:
In Europe, primary energy consumption in buildings accounts for up to 25%–40%, depending on the climate conditions. Space heating and Domestic Hot Water (DHW) contribute significantly to this energy consumption. Among the most common sources for heat generation in these appliances is natural gas. Condensing boilers can surpass the 100% energy performance over the lower heating value if the operating conditions enable the water vapor in the exhaust gases to condensate. Consequently, optimizing the operating parameters of condensing boilers is necessary to decrease the fuel consumption without hindering the water heating needs. The present work presents an experimental approach to the operating parameters of a condensing boiler that works with natural gas. The aim is to develop a theoretical model that relates the energy performance to the water temperature, set by the final user, and the excess air set by the maintenance staff.

Energia geotermalna należy w Europie do bardzo perspektywicznych odnawialnych źródeł energii pod względem możliwości jej wykorzystania w ciepłownictwie i chłodnictwie. Stwierdzenie to odnosi się zarówno do płytkiej, jak i głębokiej geotermii, zwłaszcza w perspektywie wypełniania przez państwa unijne zobowiązań dotyczących udziału energii ze źródeł odnawialnych w finalnym zużyciu energii do 2020 r., a także strategii krajowych. Przykładem kraju, w którym cele te są z powodzeniem realizowane, są Niemcy - także w przypadku ciepłowniczego wykorzystania energii geotermalnej. W artykule przedstawiono główne aspekty rozwoju tego wykorzystania, wskazując m.in. na warunki złożowe, eksploatacyjne, a także sprzyjające uwarunkowania prawne i ekonomiczne.
Geothermal energy belongs to very prospective renewable energy sources taking into account possibilities of their use for heating and cooling. This statement refers both to shallow and deep geothermics, specially in the view of fulfillment indicative targets as to the share of renewable energy sources in final energy consumption by EU-countries by 2020 as well as energy strategies in particular states. Germany is an example of the country where such targets have been successfully realized, also in case of geothermal energy. The paper presents main aspects of geothermal heating development in this country in recent years including main reservoir, exploitation conditions accompanied by favorable regulatory and financial factors.
