    Opis:
    In this paper, we introduce a hybrid iterative scheme for finding a common element of the set of solutions for a system of mixed equilibrium problems, the set of common fixed points for a nonexpansive semigroup and the set of solutions of the quasi-variational inclusion problem with multi-valued maximal monotone mappings and inverse-strongly monotone mappings in a Hilbert space. Under suitable conditions, some strong convergence theorems are proved. Our results extend some recent results in the literature.

    Opis:
    In this paper, a low kilo-volt-ampere rating zigzag connected autotransformer based 36-pulse rectifier system supplying vector controlled induction motor drives (VCIMD) is designed, modeled and simulated. Detailed design procedure and magnetic rating calculation of the proposed autotransformer and interphase reactor is studied. Moreover, the design process of the autotransformer is modified to make it suitable for retrofit applications. Simulation results confirm that the proposed 36-pulse rectifier system is able to suppress less than 35th harmonics in the utility line current. The influence of load variation and load character is also studied to demonstrate the performance and effectiveness of the proposed 36-pulse rectifiers. A set of power quality indices at AC mains and DC link are presented to compare the performance of 6-, 24- and 36-pulse AC-DC converters.

    Opis:
    Influence of aqueous phase properties and process parameters on kaolinite particle zeta potential was quantified by electrophoresis experiments. The results indicated that pH strongly altered the zeta potential of kaolinite and it decreases at the beginning and then increases in the range of pH = 2–13. The activity of different cations changes the zeta potential and has the following tendency of Al3+ > Ca2+ > Mg2+ > Na+ and the zeta potential increases due to heterocoagulation of different mineral particles in suspension. It was found that the zeta potential of kaolinite particles increases after the suspension was stirred and decreases at the beginning, and then increases with soaking time. The FTIR results showed that the zeta potential takes into account ion adsorption and the change of Si–O, Al–O and Al–OH groups on the surface of the kaolinite particles.

    Opis:
    Lack of heating uniformity is a major problem impeding the broader adaptation of radio frequency heaters in industrial applications. The overall aim of this study was to evaluate the uniformity of heating or temperature distribution within food samples (three different carrot and one radish rectangles) placed vertically and horizontally within a radio frequency heating cavity. The intensity of the electric field in radio frequency was found to be symmetrical. The temperatures at the vertically top positions were lower than the vertically bottom positions at the equidistance from the vertical center with the highest was at the vertically central position. The rate of temperature rise at all the positions were higher in taller (higher mass) than the shorter (lower mass) rectangles of carrots. The temperatures at the corners and edges were lower than at the cross sectionally central positions at all the heights tested in both carrots and radishes. The rate of temperature rise at all the vertical positions was higher in radish rectangles than in the carrot rectangles of the same dimensions. The similarity of temperature distribution in carrot and radish rectangles suggested that the heating patterns and uniformity in carrots and radishes in RF heating were almost the same.

    Opis:
    Through changing the argon pressure, CaB6 films with different crystallographic orientation and morphology on glass substrates were prepared by direct current (DC) magnetron sputtering method. The film textures, crystallite sizes, composition and morphology were investigated by a spectrum of characterizing techniques in terms of X-ray diffraction (XRD), field emission scanning electron microscopy with energy dispersive spectrometer (FESEM-EDS), atomic force microscopy (AFM), Raman shift spectroscopy. The influence of argon pressure on microstructure was studied. The average grain size increased with the argon pressure increasing from 0.8 Pa to 1.5 Pa. Meanwhile, the dominant crystal face changed from (110) to (100). Then the grain size decreased when the argon pressure increased to 2.0 Pa. The surface morphology evolved from typical cauliflower-like nanocrystalline clusters to faceted rectangular pyramids. It was found that considerable amount of argon atoms were trapped in the films. The formation process of CaB6 films was also analyzed in this paper.
    Warstwy CaB6 naniesiono na podłoża szkliste metodą magnetronowego rozpylania stałoprądowego (DC). Poprzez kontrolę ciśnienia argonu otrzymano warstwy o różnej morfologii i orientacji krystalograficznej. Strukturę, wielkość krystalitów oraz skład chemiczny warstw badano przy zastosowaniu następujących technik: dyfrakcji rentgenowskiej (XRD), skaningowej mikroskopii elektronowej w połączeniu ze spektroskopią dyspersji energii promieniowania rentgenowskiego (SEM-EDS), mikroskopii sił atomowych (AFM) oraz spektroskopii Ramana. Badano wpływ ciśnienia argonu na mikrostrukturę warstwy. Wraz ze wzrostem ciśnienia argonu z 0,8 Pa do 1,5 Pa zwiększyła się średnia wielkość ziaren przy jednoczesnej zmianie głównych kierunków krystalograficznych – z (110) w (100). Natomiast w wyniku dalszego wzrostu ciśnienia do 2,0 Pa, wielkość ziaren zmniejszyła się. Zaobserwowano także zmiany w morfologii powierzchni. Stwierdzono, że znaczna ilość atomów argonu została uwięziona w warstwach. W niniejszej pracy poddano także analizie proces powstawania warstw CaB6.

    Opis:
    With the development of tourism in the inland waters, various types of accidents in the waters have posed a great threat to human life, property, and the environment. This has caused concern in all circles of society. According to water tourism safety issues, and relying on Internet technology, shipping safety, and public safety management theory, this paper has proposed the concept and design plan of an Internet + maritime emergency management platform. This platform includes functions such as the intelligent perception of a ship’s navigation status, the scientific selection of a maritime emergency rescue site, the emergency rescue scene, the online dynamic management of maritime emergency resources, and the online production of a maritime emergency rescue plan. The design scheme has been used in the platform’s development. This paper has taken the application of the Internet + maritime emergency management platform for the Liujiaxia reservoir in the Gansu Province of China as an example. The results showed that the design of the platform that has been proposed in this paper is reasonable and that it can provide scientific, fast and accurate decision information for emergency command in the Liujiaxia reservoir and improve the effective control of the accident site as well as the use of resources.

    Opis:
    The effects of the dispersants NaOH and Na2CO3 on the classification of coal slimes was studied in a novel classification apparatus. A dispersion effect was characterized through slurry pH and transmittance measurements as well as zeta potential determinations of the slimes. The pH increased and the zeta potential became more negative, while the transmittance decreased with the increase in the NaOH and Na2CO3 addition. The miscellany rates in the overflow decreased by 15.18% and 11.22% with NaOH and Na2CO3, respectively, while that in the underflow was 31.81% and 27.08%, respectively. An ash-removal efficiency from the coal slurries increased by 20.03% and 10.50% with NaOH and Na2CO3, respectively. It was found that the largest difference in classification efficiency between these dispersants in the overflow was 26.05% and underflow was 14.86%. At the high classification efficiency, the transmittance of the slurry decreased, indicating that better dispersion effect led to the higher classification efficiency of the coal slurry. NaOH showed to be a better dispersant for coal slimes classification than Na2CO3 in the novel classification apparatus.

    Opis:
    Communication atmosphere based on emotional states of humans and robots is modeled by using Fuzzy Atmosfield (FA), where the human emotion is estimated from bimodal communication cues (i.e., speech and gesture) using weighted fusion and fuzzy logic, and the robot emotion is generated by emotional expression synthesis. It makes possible to quantitatively express overall affective expression of individuals, and helps to facilitate smooth communication in humans-robots interaction. Experiments in a household environment are performed by four humans and five eye robots, where emotion recognition of humans based on bimodal cues achieves 84% accuracy in average, improved by about 10% compared to that using only speech. Experimental results from the model of communication atmosphere based on the FA are evaluated by comparing with questionnaire surveys, from which the maximum error of 0.25 and the minimum correlation coefficient of 0.72 for three axes in the FA confirm the validity of the proposal. In ongoing work, an atmosphere representation system is being planned for casual communication between humans and robots, taking into account multiple emotional modalities such as speech, gesture, and music.
