Opis:
Federacja Rosyjska jest zainteresowana destabilizacją państw, które uznaje za swoją strefę wpływów. Dotyczy to w największym stopniu przestrzeni tzw. Świętej Rusi, czyli Ukrainy i Białorusi. Inspiruje więc działania mające na celu tzw. „wtórną nacjonalizację”, czego przykładem jest koncepcja „ruskiego miru” (Русский мир), która opiera się na integracji narodowo-kulturowej i historyczno-politycznej wspólnoty rosyjskojęzycznej. Celem niniejszego artykułu jest ukazanie roli tej koncepcji w polityce Federacji Rosyjskiej wobec Ukrainy. „Ruski mir” stanowi narzędzie rosyjskiej ekspansji geopolitycznej na terytorium tego państwa, chociaż projekt stracił zdecydowanie na znaczeniu po nadaniu Cerkwi Ukraińskiej statusu autokefalicznego 6 stycznia 2019 roku. Realizacja koncepcji wiąże się dążeniem do odzyskania statusu imperium, opierając się na przekonaniu o odrębności rosyjskiego świata cywilizacyjnego i rosyjskiej duchowości, szczególnej mesjańskiej roli rosyjskiego prawosławia oraz prawie do ekspansji politycznej i kulturowej. Wpisuje się w to także prawo do zbrojnej interwencji humanitarnej w obronie „ruskiego miru”.
The Russian Federation is interested in destabilizing the states that it recognizes as its sphere of influence. This applies to the greatest extent to the so-called Holy Rus, that is, Ukraine and Belarus. So it inspires activities aimed at the so-called „Secondary nationalization”, as exemplified by the concept of „Russkiy mir”, which is based on the pursuit of national-cultural and historical-political integration of the Russian-speaking community. The purpose of this article is to show the role of this concept in the policy of the Russian Federation towards Ukraine. "Russkiy mir" is a tool of Russian geopolitical expansion on the territory of this country, although the project lost its significance after the autocephalous status of the Ukrainian Church was granted on January 6, 2019. The implementation of the concept is associated with the desire to regain the status of an empire, based on the conviction of the exclusivity of the Russian civilization and Russian spirituality, the special messianic role of Russian Orthodoxy, and the right to political and cultural expansionism. This also includes the right to armed humanitarian intervention in defense of the "Russian world".

Opis:
Zachowany fragment ustawy municypalnej lex Osca Tabulae Bantinae jest przykładem polityki Rzymu w stosunku do pierwotnych kultur na południu Italii. Rzymianie zachowywali język oraz lokalne zwyczaje, wprowadzając jednocześnie rzymskie regulacje prawne, stanowiące podstawą organizacji i funkcjonowania miasta. Historia tej ustawy jest również przykładem, w jaki sposób redagowano i zapisywano teksty prawne na przełomie II i I w. po Chr.
The extant passage of the municipal act known as the lex Osca Tabulae Bantinae is an example of Roman policy on the primitive cultures of southern Italy. The Romans kept the language and local customs but introduced Roman legal regulations, which provided the grounds for the organization and operations of local municipalities. The history of this act is also an example of how legal texts were edited and written at the turn of the first and second centuries AD.

Opis:
In the study AVL BOOST™ is used to perform a thermodynamic simulation of a six-stroke engine, being built by a research team based in Saudi Arabia. The six-stroke cycle consists of a standard four-stroke Otto Cycle followed by a heat recovering steam expansion cycle. Water is injected into the hot combustion chamber towards the end of the Otto expansion stroke producing steam, which is used to perform work on a piston. This process produces power using waste heat and therefore increases the overall efficiency of the engine. The Robin EY28D engine, which is a single cylinder, four-stroke, gasoline engine was used for this simulation study. The engine was modelled and converted into six-stroke engine in AVL BOOST. The results show that six-stroke engine is more efficient than four-stroke engine. In six-stroke engine, the engine power is increased by 33.1% and brake specific fuel consumption (BSFC) is decreased by approximately 16%. Where emissions are concerned, Nitrogen Oxide (NOx) emission from six-stroke engine is reduced by 80%, while the Hydrocarbon (HC) emission increases by 85% compared with the original 4-stroke. Moreover, the most efficient camshaft was found and designed according to the most efficient valve profile for this engine, which is combination of 60CA° of valve duration and 10 mm of valve lifting.

Opis:
Median graphs have many interesting properties. One of them is-in connection with triangle free graphs-the recognition complexity. In general the complexity is not very fast, but if we restrict to the planar case the recognition complexity becomes linear. Despite this fact, there is no characterization of planar median graphs in the literature. Here an additional condition is introduced for the convex expansion procedure that characterizes planar median graphs.

Opis:
This paper proposes a novel computationally efficient stochastic spectral projection based approach to Bayesian inversion of a computer simulator with high dimensional parametric and model structure uncertainty. The proposed method is based on the decomposition of the solution into its mean and a random field using a generic Karhunen–Loève expansion. The random field is represented as a convolution of separable Hilbert spaces in stochastic and spatial dimensions that are spectrally represented using respective orthogonal bases. In particular, the present paper investigates generalized polynomial chaos bases for the stochastic dimension and eigenfunction bases for the spatial dimension. Dynamic orthogonality is used to derive closed-form equations for the time evolution of mean, spatial and the stochastic fields. The resultant system of equations consists of a partial differential equation (PDE) that defines the dynamic evolution of the mean, a set of PDEs to define the time evolution of eigenfunction bases, while a set of ordinary differential equations (ODEs) define dynamics of the stochastic field. This system of dynamic evolution equations efficiently propagates the prior parametric uncertainty to the system response. The resulting bi-orthogonal expansion of the system response is used to reformulate the Bayesian inference for efficient exploration of the posterior distribution. The efficacy of the proposed method is investigated for calibration of a 2D transient diffusion simulator with an uncertain source location and diffusivity. The computational efficiency of the method is demonstrated against a Monte Carlo method and a generalized polynomial chaos approach.

Opis:
Heating, ventilation and air conditional (HVAC) system provides a cold ventilation for the comfort of the driver and passengers in a vehicle. However, the vibration induced by the HVAC contributes to a reasonable level of noise emission, and hissing is one of the critical noises. So far, the characterization of hissing noise from the vehicle is least to be reported compared to other type of noises. Hence, this paper investigates the occurrence of hissing noise from several HVAC components. A lab-scale HVAC system was developed to imitate the real-time operations of the vehicle HVAC system. Two engine conditions, namely as ambient and operating conditions, were tested at speed of 850 rpm and 850-1400 rpm, with the blower speed maintained constantly at one level. The result shows that the hissing noise from the labscale HVAC was produced at frequency range of 4000-6000 Hz. The finding also highlights that the main component contributors of noise emission are an evaporator and a thermal expansion valve. The validation with a real vehicle system showed a good consensus whereby the hissing noise was produced at the similar operating frequency ranges. Also, the hissing noise was found to be louder when in an operating condition which could be taken into consideration by the vehicle manufacturers to improve the HVAC design.

Opis:
A new, state space, discrete-time, and memory-efficient model of a one-dimensional heat transfer process is proposed. The model is derived directly from a time-continuous, state-space semigroup one. Its discrete version is obtained via a continuous fraction expansion method applied to the solution of the state equation. Fundamental properties of the proposed model, such as decomposition, stability, accuracy and convergence, are also discussed. Results of experiments show that the model yields good accuracy in the sense of the mean square error, and its size is significantly smaller than that of the model employing the well-known power series expansion approximation.

In the paper, a new method for solution of linear discrete-time fractional-order state equation is presented. The proposed method is simpler than other methods using directly discrete-time version of the Grünwald-Letnikov operator. The method is dedicated to use with any approximator to the operator expressed by a discrete transfer function, e.g. CFE-based Al-Alaoui approximation. A simulation example confirms the usefulness of the method.

In this paper, a singularly perturbed system of reaction–diffusion Boundary Value Problems (BVPs) is examined. To solve such a type of problems, a Modified Initial Value Technique (MIVT) is proposed on an appropriate piecewise uniform Shishkin mesh. The MIVT is shown to be of second order convergent (up to a logarithmic factor). Numerical results are presented which are in agreement with the theoretical results.

A simple semi-recursive routine for nonlinearity recovery in Hammerstein systems is proposed. The identification scheme is based on the Haar wavelet kernel and possesses a simple and compact form. The convergence of the algorithm is established and the asymptotic rate of convergence (independent of the input density smoothness) is shown for piecewise-Lipschitz nonlinearities. The numerical stability of the algorithm is verified. Simulation experiments for a small and moderate number of input-output data are presented and discussed to illustrate the applicability of the routine.

Opis:
In this article we worked on the result and process of calculation of the gap heat transfer coefficient for a hot fuel pin in accordance with burn-up changes in the VVER-1000 reactor at the Bushehr nuclear power plant (Iran). With regard to the fact that in calculating the fuel gap heat transfer coefficient, various parameters are effective and the need for designing a model is being felt, therefore, in this article we used Ross and Stoute gap model to study impacts of different effective parameters such as thermal expansion and gaseous fission products on the hgap change rate. Over time and with changes in fuel burn-up some gaseous fission products such as xenon, argon and krypton gases are released to the gas mixture in the gap, which originally contained helium. In this study, the composition of gaseous elements in the gap volume during different times of reactor operation was found using ORIGEN code [3]. Considering that the thermal conduction of these gases is lower than that of helium, and by using the Ross and Stoute gap model, we find first that the changes in gaseous compounds in the gap reduce the values of gap thermal conductivity coefficient, but considering thermal expansion (due to burn-up alterations) of fuel and clad resulting in the reduction of gap thickness we find that the gap heat transfer coefficient will augment in a broad range of burn-up changes. These changes result in a higher rate of gap thickness reduction than the low rate of decrease of heat conduction coefficient of the gas in the gap during burn-up. Once these changes have been defined, we can proceed with the analysis of the results of calculations based on the Ross and Stoute model and compare the results obtained with the experimental results for a hot fuel pin as presented in the final safety analysis report of the VVER-1000 reactor at Bushehr [2]. It is noteworthy that the results of accomplished calculations based on the Ross and Stoute model correspond well with the existing experimental results for this reactor.

The problem is how to assess normal stresses around dynamically driven nails. Pull-out tests show that these stresses are much higher than it would follow from classical analyses. Therefore, an analysis of the cavity expansion method was applied to study this problem. It was shown that the cavity expansion method, widely applied in soil mechanics, suffers from many shortcomings. It was also shown that this method is not closely related to cone penetration tests, nor to the technology of dynamic soil nailing.

This paper presents a verification approach to thermoelastic steam turbine rotor analysis. Neither temperature nor stresses are measured on the rotor surface in utility power plants. Therefore analysis of the steam turbine rotor can be verified only based on absolute and differential thermal expansion measurements in vicinity of the steam turbine. Absolute and differential expansion measurements and steam turbine fixed points arrangement allow to calculate thermal growth of the steam turbine rotor during transients. Thermal growth of the rotor can be a baseline for the calculation using a numerical model.
