ФАКТОРНА СТРУКТУРА ПСИХОЕМОЦІЙНОГО ЗДОРОВ'Я СТУДЕНТІВ

The article highlights the results of the study of health as a subject of research within the psychological scientific fields. The scientific status of the concept of «psycho-emotional health of the individual» is substantiated; its structural and component composition is presented in the staging plan. The context of the constructs «mental health», «psychological health», «emotional health» in the expansion of scientific ideas about the psycho-emotional health of students is proved. Based on the results of factor analysis, it is established that the basis of psycho-emotional health of the individual in early adulthood is the severity and significance of emotional experiences, features of the psycho-emotional sphere of personality, emotional maturity, emotional awareness, and emotional saturation of life. As a result of using factor analysis as a means of determining correlations, a four-factor model has been established, which is aimed at determining the basics of students’ psycho-emotional health. It has been empirically established that the first factor (based on expressiveness, self-regulation, empathy and integrative level of emotional maturity, emotional awareness, and integrative level of emotional intelligence) is the most loaded. The second factor was formed by indicators of psychological resourcefulness of the individual. These are such indicators as: «success», «self-confidence», «love», «creativity» and others. At the negative pole is «maladaptation». Regarding the third factor, which is conditionally called «means of self-regulation», it was formed, in particular, indicators of the following content: «work on yourself», «control», «risk-taking», as well as the parameters of meaningful life orientations. The negative poles of this factor were «consolidation» and «escanism». The fourth factor is the factor of «social conditioning». It is formed by a number of indicators: «helping others», «satisfaction with the learning process, relationships with classmates and learning activities» and others. At the negative pole of this factor is «emotional discomfort». As a result of the factor analysis, it seemed possible to establish the vectors that form the plane of the foundations of students’ psycho-emotional health. The results of multiple regression analysis contributed to the certainty in the research position on the development of psychological strategy, which takes into account the most important segments, the set of which represents the basics of psycho-emotional health of higher education, and which can be considered its predictors. Thus, determining the stages of the psychological experiment (orientation-motivational, executive, reflective-evaluative), it seemed possible to specify the current tasks and direct the psychological support of their solution.

„Imaginarium” polskie: Norwidowska lektura Anhellego

The aim of the article is to answer the question how Cyprian Norwid understood Juliusz Słowacki’s poem entitled Anhelli (1838). Norwid’s interpretation of Anhelli, which was put forward in his lectures O Juliuszu Słowackim (1961), was significantly different from the previous ones. Before Norwid, the critics of Anhelli admired its aesthetic layer and appreciated the documentary motifs, but could not make sense of its extremely pessimistic message. Norwid, however, interpreted Anhelli as an allegorical reflection of what Charles Taylor would have called the Polish social imaginary. Emphasising the role of the metaphorical meaning of a few motifs in the world presented (especially the one of Siberia as the „negative pole” of the Polish civilisation and the picture of characters as supporters of particular ethical views), Norwid interpreted Słowacki’s poem as an allegory of a grave crisis of the Polish collective consciousness as well as a picture of the decay of the national community. In this way, Norwid’s reflection on Anhelli gave him the opportunity to criticise the qualities of the 19th-century Polish culture and the mentality of the then emigrants.

Tracking Control of High Order Input Reference Using Integrals State Feedback and Coefficient Diagram Method Tuning

The purpose of the research is tracking control to follow the input reference signal such as step, ramp, parabolic, and high order reference stably. The challenge is rising when high order input references, such as parabolic or polynomial, are used in the advanced system. Like in satellite and missile launcher systems, the triple integrator systems have to follow parabolic or polynomial trajectory with high stability required. The research proposed an integrals state feedback controller to combine simple state feedback control with cascade-layered integral control. The order of the input reference defines the structure and number of integrals used. Along with Coefficient Diagram Method in its tuning process, the proposed controller is guaranteed to have good stability and zero steady-state error. Simulation results and mathematical proofs of stability and zero steady-state error are provided on the paper. The proposed method can follow various input references such as the ramp, parabolic, polynomial, and higher-order reference based on the simulation and mathematical proofs. The stability using the pole location also shown the negative poles that give a stable system.

Common-Ground-Type Five-Level Transformerless Inverter Topology With Full DC-Bus Utilizaton

Transformerless inverters (TIs) are widespread in photovoltaic (PV) applications due to their low cost and high efficiency. However, TIs suffer due to leakage current as a consequence of PV parasitic capacitance, and high-frequency common-mode voltage, which has resulted in the emergence of several topological and control scheme modifications. In this article, a switched-capacitor (SC) based inverter capable of synthesizing a five-level voltage is proposed. In the devised structure, the negative pole of the dc bus is directly connected to the grid neutral, thereby resulting in zero leakage current. In addition, industrial standard half-bridge modules can be employed directly for implementing the proposed inverter without modifications, making it more practically feasible. The proposed topology has the capability of self-voltage balancing of SC, reactive power processing, and full dc-bus utilization as opposed to half-bridge topologies. The principle of operation and a simple logic-gate-based pulse generation scheme is presented in detail. Simulation and experimental results confirming the practical viability of the proposed topology are presented. Finally, the superior features and the merits of the proposed topology are shown through a detailed comparison against state-of-the-art topologies.

An Improved DC Fault Protection Algorithm for MMC HVDC Grids Based on Modal-Domain Analysis

To detect the dc faults for the modular multilevel converter (MMC)-based dc grids using overhead line transmission, many protection methods in phase-domain have been proposed. These existing protection methods suffer from incomplete function, weak theoretical basis, and sensitivity to fault resistance and noise disturbance. To overcome these shortcomings, this article proposes an improved dc fault protection algorithm using the modal-domain approach for the MMC-based overhead dc grids, which decouples the interaction between positive and negative poles and mitigates the strong frequency dependence of the characteristic impedance in phase-domain. The dc fault equivalent circuits are established in modal-domain and the fault characteristics during the initial stage are analyzed. Based on the modal-domain analysis, the line-mode reactor voltage which combines the fault characteristics of negative and positive reactor voltages is used to identify the internal faults. The zero-mode reactor voltage which enlarges the differences between faulty and healthy poles is used to select the faulted pole. This method is robust to fault resistance and noise with high detection speed. In addition, it is not affected by power reversal, ac faults, and dc circuit breaker (DCCB) operation, which are validated and evaluated by the simulations in PSCAD/EMTDC.

Faulty feeder selection and segment location method for SPTG fault in radial MMC‐MVDC distribution grid

As a modular multilevel converter-based medium-voltage direct current (MMC-MVDC) distribution grid mostly utilises small current grounding modes, the weak fault current for single-pole-to-ground (SPTG) fault is very difficult to detect especially in the case of noises and fault resistance. Therefore, this study proposes a fast and accurate faulty feeder selection and segment location method. For SPTG fault, the transient current fault component is the charge-discharge current of distributed capacitance on the DC feeder. Analysis indicates that the waveforms of current fault component of positive and negative poles are negatively correlated for a faulty feeder; while they are positively correlated for a non-faulty feeder. According to these characteristics, a faulty feeder selection criterion using Pearson correlation coefficient (PCC) is constructed. Then, utilising the energies difference between the current fault components of two poles, the faulty pole can be verified. In addition, the faulty segment is located by the PCC of the current fault component on both sides of each segment. Finally, simulation results confirm the validity of the proposed faulty feeder selection and segment location method.

Estimation of HVDC transmission lines shielding failure using LPM method and an adapted SLIM model

In this study, the shielding system of HVDC transmission lines against direct lightning strokes is analysed and the shielding failure rate is investigated. The lightning downward leader is modelled using 3D leader progression model (LPM) and the striking point is distinguished employing the self-consistent upward leader inception and propagation model (SLIM). For determination of striking point more accurately, the required parameters of SLIM model are extracted from the recent experimental results. Different effective objects in the space of study including cloud, lightning channel, towers, wires, and ground are modelled using fictitious charges. Moreover, the charge simulation method is used for electric field calculation. Using the foregoing model, the shielding failure rate of an HVDC transmission line is calculated. Also, the percentages of lightning strokes to each part of the structure are obtained in order to investigate the differences between the positive and negative poles in attracting the lightning. In addition, the effect of height and shielding angles of positive and negative poles are studied. All the results are compared with those of electrogeometric model models.

Unbalanced Voltage Suppression in a Bipolar DC Distribution Network Based on DC Electric Springs

In this paper, a method is proposed to mitigate unbalanced voltage and reduce power losses due to neutral line current in a bipolar direct current (DC) distribution network by introducing a DC electric spring (DC-ES). The coupling relationship between positive and negative pole voltages are investigated given the resistance of neutral line in the bipolar DC distribution network. The coupling matrixes of the positive and negative pole voltages and the DC-ES output voltages are deduced. And this matrixes demonstrate that the DC-ES control system is composed of double inputs of pole voltages and double outputs of DC-ES voltages. The small-signal model of the bipolar DC distribution network with DC-ESs is derived further. Subsequently, the control system with double inputs and outputs is transformed into two independent control systems by introducing the decoupling control variables, thereby increasing its rapidity and anti-interference performance significantly. The proposed unbalanced voltage suppression method and decoupling control of DC-ESs are validated by simulations and experiments.

The new effect of neodymium magnet (NdFeB) on storage quality of potatoes

Modern techniques of potato tubers storage have a number of economic, technical, and technological disadvantages and they don’t ensure high product safety - potato losses run up to 30 % per storage season. The work has been conducted on the effect of magnetic field of neodymium (NdFeB) magnet on sprouting, weight loss and storage of potatoes because this method is the most interesting and understudied. The equipment used in the research: equipment for magnetic potato treatment, NdFeB magnets, magnetometer is used to identify positive and negative magnetic poles, and auxiliary instruments. As a result of the experimental studies it has been found that untreated potatoes had weight loss of 39 %. Weight loss of potatoes treated with positive magnetic field of 330…350 mT and time treatment 60…180 s was 4 %. The positive magnetic field of 330…350 mT was effective in suppressing sprout growth. It is also to inhibit sprout growth in potatoes stored at 25°C. Potatoes receiving more than 330…350 mT dose, were higher in length of sprouts, and higher weight loss of potatoes (20…50 %). Also, potatoes receiving negative magnetic field dose, were higher in length of sprouts, and higher weight loss (60 %) than those given positive magnetic field dose. As a result of experiments, the design of a new device for magnetic processing of potatoes has been developed. It is anticipated that magnetic fields influence the potato cells, as the result of the effects, potato tubers either lock in moisture, starch and other substances, or lose them quickly due to inner-structure destruction.

Operation of the full‐bridge three‐level DC–DC converter in unbalanced bipolar DC microgrids

As compared to two-wire, unipolar DC microgrids (DCμGs), bipolar DCμGs apply a positive, neutral and negative conductor to increase the power transfer capability while retaining two voltage levels for supplying low- and high-power devices at an appropriate voltage. However, connecting devices between the positive or negative pole and the neutral conductor will result in unbalanced currents causing voltage to unbalance. Therefore, power electronic converters with voltage balancing capability are essential. Instead of installing dedicated voltage balancing converters, this study proposes to apply three-level DC–DC converters. These converters can interface battery storage with bipolar DCμGs and balance the pole-to-neutral voltages at the same time. However, high levels of unbalanced currents drive three-level DC–DC converters towards their theoretical unbalanced operating limits. To derive these, a method is presented which decomposes the governing equations in balanced and unbalanced components. Although the method is generally applicable to the three-level converters, the full-bridge three-level converter serves as a comprehensive example. The method enables to derive the unbalanced operating area of three-level DC–DC converters and to appropriately size the filter inductor. Furthermore, a novel modulation strategy is introduced in order to lower the inductor current ripple in unbalanced conditions, supported by experimental results.

HD 96446: a long-period binary with a strongly magnetic He-rich primary with β Cephei pulsations

Aims. HD 96446 is a magnetic B2p He-strong star that has been reported to be a β Cep pulsator. We present a detailed spectroscopic analysis of this object based on an intensive observational data set obtained in a multisite campaign with the spectrographs CORALIE, FEROS, and HARPS (La Silla); UVES (Paranal); HERCULES (Mt. John Observatory); and GIRAFFE (SAAO). Methods. Radial velocities were measured by cross-correlations and analysed to detect periodic variations. On the other hand, the mean spectrum was fit with spectral synthesis to derive atmospheric parameters and chemical abundances. Results. From the analysis of radial velocities, HD 96446 was found to be a spectroscopic binary with a period of 799 days. The stellar companion, which contributes only ∼5% of the total flux, is an A0-type star. A frequency analysis of the radial velocities allowed us to detect two pulsational modes with periods 2.23 h and 2.66 h. The main mode is most probably a low-inclination, dipole mode (l, m) = (1, 0), and the second pulsation mode corresponds to (l, m) = (2, 2) or to a pole-on (l, m) = (3, 2) configuration. In addition to radial velocities, the main pulsation mode is evidenced through small variations in the spectral morphology (temperature variations) and the light flux. The rotation period of 23.4 d, was detected through the variation in line intensities. Chemical abundances are unevenly distributed over the stellar surface, with helium concentrated at the negative magnetic pole and most metals strengthened at lower latitudes. The mean chemical abundance of helium is strongly abnormal, reaching a value of 0.60 (number fraction).

Power shift‐based optimal corrective control for bipolar multi‐terminal high‐voltage direct current grid

The bipolar modular multi-level converter-based multi-terminal high voltage direct current (MTDC) grid offers an attractive solution to cope with the increased renewable power generation integration and power transfer capability. However, the N − 1 outage of direct current transmission lines and converters may result in overloads of other components and renewable power generation congestion. This study presents a power shift-based optimal corrective control method to guarantee the operational security of the system with bipolar MTDC grid embedded. First, the principle of power shift in the bipolar MTDC grid is analysed. The grid features in isolated positive and negative poles and can provide up to 50% transmission redundancy. Following an N − 1 contingency, certain power can be shifted from the faulty pole to the healthy pole or between different converter stations. Second, two optimisation models are, respectively, established for the MTDC and alternating current grids to address the power shift-based optimal corrective control. The proposed method guarantees operational security of the system while the amount of renewable power generation accommodation by the MTDC grid is maximised. Finally, the method is applied to the real-life Zhangbei ±500 kV four-terminal bipolar high-voltage direct current grid. Numerical results and electromagnetic transient simulation verify the effectiveness of the presented method.

Unified dispersion model for the electric susceptibilities of physically realizable materials

Based on the powerful method of network control theory, a complete, classically derived, broadband, analytic dispersion model is presented which describes electric susceptibility for a rigorously physically realizable, dielectric material system with a possible dc conductivity contributor. The analysis results in a susceptibility model constructed entirely from pole-residue groups. As a result, solitary Debye-type poles are not physically supported in the broadband analytic dispersion theory presented in this paper. While previous investigators have focused primarily on modeling susceptibility using only negative complex-conjugate poles, the type found naturally at optical frequencies and above, this analysis was conducted under no such restriction; hence, it is considered unified and should apply to all classical-type susceptibility behavior at all frequencies from dc to daylight, including some of the ultraviolet region where the material-continuum assumption begins to break down. Excluding conductivity due to the absence of any proof of magnetic monopole existence, the model should be equally applicable for modeling magnetic susceptibility dispersion. Based upon a rigorous emphasis on physical realizability, the complete, classical dispersion model is demonstrated by successfully modeling the complex permittivity of liquid water at 25 \ifmmode^\circ\else\textdegree\fi{}C using measurement data from 30 MHz to 1200 THz.

The response of electronic and energetic properties of conjugated vs aromatic molecules to an external uniform electric field

The susceptibility of electric and energetic properties of two sets of molecules to perturbation in a uniform electric field was investigated. The molecules of one set were deca-1,3,5,7-pentaene terminated with two functional groups, R1 and R2; those of the second set were 4-R1-4′-R2-p-diphenylbenzenes, with R1 and R2 being the same as in the polyene set. The polyene and aromatic molecules had similar lengths of the system of conjugated bonds between the two most extreme carbon atoms. Dipole moments were used as determinants of the overall charge transfer within the molecules. The electric field was directed along the main (longest) axes of the molecules from the negative pole to the positive. Comparison of the effect of the charge relocation in both sets of conjugated molecules revealed that the charge transfer imposed by the electric field was more efficient in the polyenes than in the aromatic compounds; however, for the molecule pairs with the same R1 and R2, reversal of the dipole moment direction falls at the same field strength. Parabolic dependence of the molecules’ energy as a function of field strength can also be interpreted in terms of the response of electron density to an electric field.

Operation of an inverting &lt;i&gt;DC-DC &lt;/i&gt;converter with charge pumping and &lt;i&gt;LDO &lt;/i&gt;in the &lt;i&gt;LM &lt;/i&gt;27762 microcircuit

The paper focuses on the study of operation of an inverting DC-DC converter with charge pumping and LDO, which are the part of the combined bipolar secondary power supply LM 27762. The measurements covered two modes amply included in the range of normalized parameters with input voltages equal to 3.5 and 5.5 V, and output voltages 1.8 and 4.9 V, respectively, as well as the mode with an input voltage of 5.0 V and an output voltage 4.7 V, with a difference in the input and output voltage not exceeding the normalized limit of the voltage drop across LDO . Pulsations of voltages were measured at various load currents from 15 to 250 mA at the positive and negative poles of the flying capacitor, at the output of the charge pumping system and, in the latter case, also at the output of the microcircuit. Based on the results obtained, it was shown for the first time how at low load currents up to about 100 mA the charge pumping system operates in the burst mode, and at higher currents, it operates in the charge pumping mode with a constant frequency

Preliminary Knowledge of Super-Substance Studying (2) — The Almighty King Kong Sutra of Going to the Parallel Cosmos of Super-Substance of Full Text Chinese to English

King Kong Prajna Paramita（going to the parallel cosmos of super-substance）utra full text translator. The static mass exists in the direction perpendicular to the direction of motion of the photon. Which is photon has dynamic inertia in the direction perpendicular to the direction of motion of the light; this has long been confirmed by scientific experiments. Positive and negative electron encounters will become a pair of gamma photons, simultaneously; a pair of gamma photons will be transformed into a pair of and negative electrons. This fully explains that and negative electrons are composed of photon, which is and negative electrons are composed of electricity and magnetism; this is uniform with the existence of static mass in the direction of motion perpendicular to the photon. Which is when the photon moves along the surface of and negative electrons in and negative electrons, the photon rotating moving in the curved space, the static mass expressed in the direction perpendicular to the motion of the photon is the mass of and negative electrons. Both positrons and negative electrons can be produced in protons and neutrons that make up the nucleus. This fully demonstrates that protons and neutrons are composed of and negative electrons. Other particles can be produced by protons and neutrons in a high-energy particle collider, indicating that other particles are also composed of and negative electrons. From this, in the everything is composed of two elements, namely electricity and magnetism. Simultaneously, electricity and magnetism form positrons and negative electrons, and in addition to everything in the electricity and magnetism also form a magnetic pole (north magnetic pole) and a negative magnetic pole (south magnetic pole). Thus, and negative electrons constitute the universe and the and there is a universal repulsive force between the universe and the universe; the and negative magnetic poles constitute the universe of the magnetic universe and the there is also a universal repulsive force between the universes and the universe. Therefore, in the world, it consists of four universes: the the the magnetic and the universe. Our big bang is just like an electronic one, called the material universe, and also the antimatter universe, the positive magnetic universe, the antimagnetic universe, these four A cosmic child, due to the existence of universal repulsive force and universal gravitation, will form a greater balance. Through the above analysis, we have reason to believe that in addition to the existence of electrical and magnetic elements, there will certainly be other countless single elements, two elements, three elements, four elements... Only these existences that are related to matter can now be identified in two ways: the brightness (golden) single element exists in the and the darkness single element exists in the universe. These two universes exist in parallel cosmos with our that is, in our surroundings and in space, in addition to matter; there are material-related brightness elemental elements and darkness elemental elements. This is all the laws and phenomena elaborated in Buddhism.

MODERN SANATTA GÖSTERİLEMEYENİN GÖSTERİLMESİ

The desire of the world of Western thought to create a language with perfect rationality to represent the world precisely has brought the reality into a process of reproduction in a concept or artwork. In addition, a series of changes that began in the 1900s led to radical transformations in the perception of reality. Now what we call reality is not conceived in an immediate spontaneity. The way we perceive reality together with the impressionist picture is involved in the subject of the picture, that is, the relationship between the perceived and the perceived has become inevitable. It is concluded that our perception of things within this relationship with cubism does not contain certainty, and the perception and perception is suspicious. All the attempts of modern art for a more accurate perception, artistic experiment could not escape the feeling of failure. At the end of this process, there is a belief that this representation is not possible. From this point on, western art has taken a new phenomenon into its agenda. If such a representation is not possible, perhaps the only thing to do is to show that we cannot represent. This was the negative pole of the show. In this way, the abstract, symbolic forms of this negative representation will be seen.
