    Opis:
    In a PV-dominant DC microgrid, the traditional energy distribution method based on the droop control method has problems such as output voltage drop, insufficient power distribution accuracy, etc. Meanwhile, different battery energy storage units usually have different parameters when the system is running. Therefore, this paper proposes an improved control method that introduces a reference current correction factor, and a weighted calculation method for load power distribution based on the parameters of battery energy storage units is proposed to achieve weighted allocation of load power. In addition, considering the variation of bus voltage at the time of load mutation, voltage secondary control is added to realize dynamic adjustment of DC bus voltage fluctuation. The proposed method can achieve balance and stable operation of energy storage units. The simulation results verified the effectiveness and stability of the proposed control strategy.

    Opis:
    The following paper addresses the issue of constructions with predicative adjectives in Polish. The main focus of attention will be put on adjectives which are governed by the copula in the infinitive form, as here one can observe some interesting casus alternation between the nominative and the instrumental. On the basis of the author’s own empirical analysis it will be examined which factors determine the choice of the casus. As it seems it is both the syntactic status of the infinitive construction and lexical factors.

    Opis:
    In order to simulate non-symmetrical boundary layer suction in an annular compressor, a cascade investigation has been performed with single-sided suction slots only. A preceding investigation had revealed a high potential for loss reduction by two different types of boundary layer suction. The experimental investigation was performed with five NACA 65-k48 stator blades at the design Mach number of 0.67 and Reynolds number of 560.000. The two investigated suction geometries are a narrow slot following the design of Peacock and a wider slot of own origin, both slots are positioned on one side of the passage only. The Peacock slot is placed in the corner between suction side of the vane and the side wall, the wider slot is positioned from suction side to pressure side following the side wall’s flow detachment line. With half the suction rate of the preceding investigation the efficiency of the cascade could still be enhanced. In the case with 2.5% suction rate the total pressure loss coefficient of the full passage was decreased by 13%, in the case with 1% suction rate the loss coefficient was decreased by even 10%. The outflow of the cascade is as expected no more symmetrical and the one sided suction has no large impact on the flow of the opposite side of the passage.
    W pracy przeprowadzono symulację problemu zasysania czynnika w niesymetrycznej warstwie przyściennej sprężarki, analizując kaskadę z jednostronnymi wlotami ssącymi. Badania poprzedzające ujawniły wysoki potencjał w ograniczaniu strat przy zastosowaniu dwóch różnych rozwiązań sposobu zasysania w warstwie przyściennej. Doświadczenia przeprowadzono, używając pięciu łopatek kierownicy sprężarki NACA 65-K48 projektowanej do przepływu przy prędkości 0.67Ma i liczby Reynoldsa 560000. Geometria obydwu rozwiązań zasysania wykorzystuje projekt wąskiej szczeliny wlotowej R.E. Peacocka oraz projekt własny szczeliny szerszej, przy czym obydwa typy umiejscowiono wyłącznie po jednej stronie kanału przelotowego. Szczelinę Peacocka umieszczono w rogu pomiędzy stroną ssącą łopatki oraz ściany, natomiast szczelina szeroka pokrywa obszar od strony ssącej do sprężającej wzdłuż linii odrywania przepływu. Przy tempie zasysania stanowiącym połowę wydatku stosowanego w poprzedzających badaniach nadal odnotowano możliwość zwiększenia sprawności kaskady. Przy spadku tempa ssania do 2.5%, współczynnik całkowitych strat ciśnienia zmalał o 13%, natomiast dla dalszego spadku do 1% współczynnik ten zmniejszył się o 10%. Zgodnie z oczekiwaniami wypływ z kaskady utracił symetrię, a zasysanie jednostronne nie zmieniło znacząco charakteru przepływu na przeciwnej stronie kanału przelotowego.

    Opis:
    The article presents two studies based on the assumption that the effectiveness of cognitive control depends on the subject’s type of emotional state. Inhibitory control is taken into account, as the basic determinant of the antisaccade reactions and the emotional Stroop effect. The studies deal with differentiation of emotions on the basis of their origin: automatic (due to primary affective reactions) vs. refl ective (due to deliberative evaluation). According to the main assumption, automatic emotions are diffusive, and decrease the effectiveness of cognitive control. The hypothesis predicted that performance level of both the Antisaccade Task and the Emotional Stroop Test would be lower in the automaticemotion eliciting condition than in the refl ective-emotion eliciting condition. In two experimental studies, positive and negative (automatic vs. refl ective) emotions were elicited. The results support the predictions, regardless of the valence of emotions.

    Opis:
    This article focuses on the Swedish reforms of upper secondary schools and their effects during the period of 1991–2017. The reforms were conducted in the spirit of New Public Management (NPM) and generated many more problems than solutions. The purpose of this article is to prepare a foundation for further research by mapping: What do we know about the NPM reforms within the Swedish upper secondary schools? What kind of knowledge is still missing and should it be developed? With the assistance of Roland Almqvist’s (2006) understanding for the NPM movement divided into three theoretical perspectives (marketization, contract management, and decentralization), we propose a literature study. This study showed that the Swedish reforms of the upper secondary schools contributed to growing social segregation among students, students’ decreasing performance in science, reading and mathematics that proved to be under the Organisation for Economic Co-operation and Development (OECD) average, and teachers experienced a lack of autonomy and de-professionalization. The political promises about “school for all” and “social inclusion” either were not fulfilled or the reform effects were not investigated well enough. Despite all research being done, we do not know what kind of Swedish upper secondary school represents a good practice for the future.

    Opis:
    Improved Blowing and Suction System (IBSS) is a novel concept that can be effectively implemented in future aircraft to improve the aerodynamic performance of aircraft wings. The proposed IBSS consists of a regular wing without its secondary control surfaces and with a Pump. The injection and suction system is used to create additional flow without disturbing the main flow over the aerofoil which effectively delays the boundary layer separation. The injection and suction areas are kept constant and they are located just below the maximum thickness point and suction is created close to the trailing edge. This paper presents a detailed numerical analysis of the proposed IBSS and the study shows that the stalling angle of attack is increased by 60% while the coefficient of lift is increased 37.5% compared to the baseline aerofoil. Also, the commercially used coflow jet (CFJ) method stalls at a 12° angle of attack whereas with the proposed IBSS method the stall occurs at a 16° angle of attack. The stalling angle is thus delayed by 33%, thus increasing the aerodynamic performance of the wing as compared to the existing methods. Also, any malfunction in IBSS does not significantly affect the performance of the aircraft. The implementation of IBSS will lead to a reduction in the weight of the aircraft and the elimination of secondary control surfaces.

    Opis:
    The purpose of the study was to find personality and family predictors of aggressive coping strategies in adolescent youth in situations of social conflict. The Questionnaire for Analysis of Coping Strategies in Adolescents in Situations of Social Conflict (Kwestionariusz do badania strategii radzenia sobie młodzieży w sytuacji konfliktu społecznego, KSMK; designed by D. Borecka-Biernat), the Questionnaire for Analysis of the Sense of Control (Kwestionariusz do Badania Poczucia Kontroli, KBPK; designed by G. Krasowicz and A. Kurzyp-Wojnarska, the Stress Assessment Questionnaire (Kwestionariusz Oceny Stresu, KOS; designed by D. Włodarczyk and K. Wrześniewski), as well as M.Plopa’s Parental Attitude Scale (Skala Postaw Rodzicielskich, SPR) were used in the study. The empirical research was conducted in secondary schools on a sample of 893 adolescents (including 468 girls and 425 boys) in the age range of 13 to 15. In the light of the conducted studies it was determined that a strong conviction of the influence of other people on positive or negative outcomes of events , as well as the assessment of a situation of conflict as threat coincides with aggressive coping strategies in youth in situations of social conflict. The analysis of the results has revealed that the tendency to react aggressively to emotional tension generated in social conflict is shaped by an inappropriate parental attitude, characterized by an emotional distance of a parent to their adolescent child.
