Abstract:

Based on the combination of modal analysis technology and finite element method (FEM), the modal parameters identification of the main parts of a diesel engine (crankshaft ,connecting rod and oil pan) were tested using hammer beat method and calculated by means of I-DEAS software. The natural frequency and shake mode parameters of the parts were identified. The results could provide basis for structure dynamic analysis and control of noise of the diesel engine.

Abstract Wind energy is one of the most important technologies for a climate-neutral energy supply. However, the premature failure of wind turbines due to unknown loads leads to a reduction in competitiveness compared to other energy sources. Here, load monitoring systems can make a significant contribution to the prevention of such failures. Most load monitoring systems for wind turbines focus on strain signals of structural components as the tower, main shaft or the rotor blade root. Based on these signals, axial forces, torsion or bending moments, which are acting on these components, are c

Abstract:

Food adulteration, mislabeling and fraud, either unintentional or deliberate, is a worldwide and growing concern. Current challenges associated with food adulteration comprise many topics: geographic origin, breed/variety identification, production method, feeding regime, technological processing, undeclared components, detection of genetically modified organisms and species substitution are the most common frauds. Accurate and reliable analytical methods are needed to monitor and control food authenticity and to guarantee correct and accurate labeling of foodstuffs, assuring that the componen

Abstract:

The work studies the cumulative modulating effect of the geometry of the interplanetary magnetic field's neutral current sheet and solar activity on propagation of galactic cosmic rays in the heliosphere. The role of each factor on the modulation of cosmic rays is estimated using a method of main components. The application of the method to experimental data on solar activity, to the tilt angle of the neutral sheet, and cosmic ray intensity for a long period from 1980 to 2018 allows us to reveal the temporal dynamics of roles of these factors in the modulation. The modulation character is show

The article under consideration aims to explore the main artistic and semiotic components of Yevhen Pluzhnyk’s poetry, reveal their semantic load in the works, and determine the figurative dominants of the artist’s life philosophy presented in his lyrics. To achieve this goal, we used the following methods: the systematization of the selected material, the method of observation, analysis, synthesis, and the descriptive method. Intertextuality made it possible to consider the poetic heritage of the writer from the point of view of textual connections with contemporary authors and his predecesso

Abstract:

A method for forecasting geomagnetic storms using the realization of the global survey method in real time is presented. The method is based on data from the worldwide network of neutron monitors NMDB. Using this method, we analyze the behavior of components of three-dimensional angular distribution of cosmic rays in the interplanetary medium, which were due to the first two spherical harmonics, over the period from 2013 to 2018. We have established that the main parameters that respond to the arrival of geoeffective disturbances of the interplanetary medium at Earth are changes in amplitudes

The first stage of the study involved interviewing 77 Moscow schoolgirls aged 12–14. The girls were asked to express their associations, thoughts, or value judgments related to women’s weightlifting. The obtained data were processed using qualitative and quantitative content analysis. The second stage of the study focused on selecting antonymic (opposite in meaning) pairs of statements characterizing women’s weightlifting. Thus, a set of 31 bipolar sca

Using X-ray power diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR), the chemical composition of urinary nanocrystallites from 3 calcium phosphate (CaP) stone-formers were investigated and compared with that from healthy subjects. The main components of nanocrystallites in urine of CaP stone formers were uric acid and CaP, while that in healthy urine was mainly uric acid, which indicated a significant difference. This study purposed an accurate detection method of urinary nanocrystallites, namely washing the urinary crystallites samples with double distilled water, which ca

Full Function Point measurement method (COSMIC-FFP) is too abstract and difficult to be applied to object-oriented software. By analyzing the notional relationship between main components of UML and main elements of COSMIC-FFP, we establish 22 measurement mapping rules, propose UML-Based COSMIC-FFP method and list the measurement process and measurement steps. An example is given and the results show that this method can measure the functional size of object-oriented software objectively and effectively.
