    Opis:
    A novel approach to designing stable fuzzy controllers with perception-based information using fuzzy-arithmetic-based Lyapunov synthesis in the frame of computing with words (CW) is presented. It is shown that a set of conventional fuzzy control rules can be derived from the perception-based information using the standard-fuzzy-arithmetic-based Lyapunov synthesis approach. On the other hand, a singleton fuzzy controller can be devised by using a constrained-fuzzy-arithmetic-based Lyapunov synthesis approach. Furthermore, the stability of the fuzzy controllers can be guaranteed by means of the fuzzy version of Lyapunov stability analysis. Moreover, by introducing standard and constrained fuzzy arithmetic in CW, the "words" represented by fuzzy numbers could be efficiently manipulated to design fuzzy controllers. The results obtained are illustrated with the design of stable fuzzy controllers for an autonomous pole balancing mobile robot.

    Opis:
    As a form of urban green space, community gardens have provided urban residents with various environments, to satisfy their social, economic and health interests. For the purposes of creating public, open and shared spaces, this article summarizes and contrasts the history of the community garden development in Europe and America, while analyzing the development situation of China as well. Taking “the Kid’s Garden” in Hunan Agricultural University as an example, the authors discuss the whole practice process in three aspects: the layout design, the construction process, and the operation and maintenance plan. Finally, the conclusion of the article presents a community garden building model, which is supported by universities with the goals to reward the society, as well as to provide a win-win result between practice and teaching. This experience is hoped to popularize community gardens and to make a contribution towards a harmonious society.

    Opis:
    In this paper, using cloud model and Delphi, we build a comprehensive evaluation cloud model to solve the problems of qualitative description and quantitative transformation in ship navigation adaptability comprehensive evaluation. In the model, the normal cloud generator is used to find optimal cloud models of reviews and evaluation factors. The weight of each evaluation factor is determined by cloud model and Delphi. The floating cloud algorithm is applied to aggregate the bottom level’s evaluation factors, and comprehensive cloud algorithm is used to aggregate the highest level’s evaluation factors to get comprehensive evaluation cloud model. Finally, evaluation result is got by matching comprehensive evaluation cloud model and optimal cloud model of reviews. As case study, the model is applied to the small LNG ship’s navigation adaptability in Southeast Asia. Compared with the fuzzy comprehensive evaluation method, the model proposed in this paper is more intuitive and reliable in comprehensive evaluation of the small LNG ship’s navigation adaptability.

    Opis:
    Future wide-swath altimetry missions will provide high-resolution information about ocean surface elevation, and facilitate the characterization of meso- and sub-mesoscale ocean activities. In this study, the demand analysis of three-dimensional (3D) oceanic state reconstruction on wide-swath SSH data features was evaluated using a data assimilation strategy. Three groups of experiments were performed to determine if the wide-swath altimetry observations would improve the three-dimensional (3D) field estimates of ocean temperature-salinity-velocity (T-S-V), and to evaluate how the spatial and temporal resolution and accuracy of the wide-swath altimetry observations affected the ocean state estimation. The Regional Ocean Modeling System and the four-dimensional variational data assimilation method were used in the experiments, with numerical simulation for the Taiwan region at a resolution of 1/10° as the example. The sensitivity of the 3D ocean state construction to the wide-swath altimetry measurements was also investigated. The results showed that the wide-swath sea surface height (SSH) measurements would have an overall positive impact on the 3D T-S-V field and that the positive effect would increase as the resolution and accuracy of the observations increased, but the net benefits would gradually decrease. Among the three examined features of the wide-swath altimetry observations, the temporal resolution had the most influence on the 3D ocean state analysis.

    Opis:
    An improved deflectometry for wavefront measurement using a composite fringe is proposed to reduce the projection fringes and improve the accuracy. The single composite fringe contains four fringes in different directions. It goes through the tested objects and then is captured by a CCD camera. Two high frequency orthogonal fringe patterns and two single period orthogonal fringe patterns can be obtained from the composite fringe by fast Fourier transform. The unwrapping of the wrapped phase of the high frequency fringe is accomplished by the corresponding single period fringe using a heterodyne method. The wavefront is reconstructed by the integration of partial derivatives. Using only one fringe, the proposed method is more applicable to dynamic wavefront measurement. The experimental results demonstrate that the proposed method can retrieve the complex wavefronts more accurately.

    Opis:
    In order to completely eliminate, or greatly reduce the number of phase wraps in 2D wrapped phase map, Gdeisat and co-workers proposed an algorithm, which uses shifting the spectrum towards the origin. But the spectrum can be shifted only by an integer number, meaning that the phase wraps reduction is often not optimal. In addition, Gdeisat’s method will take much time to make the Fourier transform, inverse Fourier transform, select and shift the spectral components. In view of the above problems, we proposed an improved method for phase wraps elimination or reduction. First, the wrapped phase map is padded with zeros, the carrier frequency of the projected fringe is determined by high resolution, which can be used as the moving distance of the spectrum. And then realize frequency shift in spatial domain. So it not only can enable the spectrum to be shifted by a rational number when the carrier frequency is not an integer number, but also reduce the execution time. Finally, the experimental results demonstrated that the proposed method is feasible.

    Opis:
    This paper reviews two techniques that have been recently published for three-dimensional profilometry and proposes one shot profilometry using iterative two-step temporal phase-unwrapping by combining the composite fringe projection and the iterative two-step temporal phase unwrapping algorithm. In temporal phase unwrapping, many images with different frequency fringe pattern are needed to project, which would take much time. In order to solve this problem, Ochoa proposed a phase unwrapping algorithm based on phase partitions using a composite fringe. However, we found that the fringe order determined through the construction of phase partitions tended to be imprecise. Recently, we proposed an iterative two-step temporal phase unwrapping algorithm, which can achieve high sensitivity and high precision shape measurement. But it needs multiple frames of fringe images which would take much time. In order to take into account both the speed and accuracy of three-dimensional shape measurement, we get a new, and more accurate unwrapping method based on a composite fringe pattern by combining these two techniques. This method not only retains the speed advantage of Ochoa’s algorithm, but also greatly improves its measurement accuracy. Finally, the experimental evaluation is conducted to prove the validity of the proposed method.

    Opis:
    The new neopterygian fish taxon Luoxiongichthys hyperdorsalis gen. et sp. nov. is established on the basis of five specimens from the second member of the Guanling Formation (Anisian, Middle Triassic) from Daaozi Quarry, Luoping, Yunnan Province, Southwest China. The new taxon is characterized by the following characters: triangular body outline with a distinct apex located between skull and dorsal fin; free maxilla; slender preopercular almost vertical; three suborbitals; at least eight strong branchiostegals with tubercles and comb−like ornamentation on the anterior margin; clavicles present; two postcleithra; ganoid scales covered by tubercles and pectinate ornamentation on the posterior margin with peg−and−socket structure; hemiheterocercal tail slightly forked. Comparison with basal actinopterygians reveals that the new taxon has parasemionotid−like triangular symplectics, but a semionotid opercular system. Cladistic analysis suggests that this new genus is a holostean, and either a basal halecomorph or basal semionotiform.

    Opis:
    The fossil record of coelacanths is patchy, with very few taxa known from the Triassic of Asia. We report here two new genera and species of coelacanths from the Luoping Biota, a recently found site of exceptional fossil preservation from Yunnan, South China. The first new taxon, Luopingcoelacanthus eurylacrimalis, is based on four specimens, which to− gether show most aspects of the anatomy. One specimen shows two small coelacanths inside the ventral portion of the ab− dominal cavity, and these are interpreted as intrauterine embryos, close to birth size, based on comparisons with previ− ously reported embryos of the fossil coelacanths Rhabdoderma and Undina, and the extant genus Latimeria. Our new find extends the evidence for ovoviviparity in coelacanths back from the Late Jurassic to the Middle Triassic. The second new taxon, Yunnancoelacanthus acrotuberculatus, is based on one specimen, and differs from Luopingcoelacanthus in the dentary, lachrymojugal, number of rays of the first dorsal fin, and especially in the ornament on dermal bones and scales. Acladistic analysis shows that the new taxa are closest relatives to the derived clade Latimerioidei. The relatively high di− versity of coelacanths in the Early Triassic, and adaptations of living Latimeria to low−oxygen conditions, suggests that the group may have included ‘disaster taxa’ that benefited from anoxic and dysoxic ocean conditions in the aftermath of the end−Permian mass extinction.

    Opis:
    In China, species in the genus Acorus are used for many different purposes, viz., in traditional medicine, for rituals, and as ornamental plants. Acorus calamus (sweet flag) has been a symbolic plant in Chinese culture for many centuries and is used as a ceremonial object in festivals throughout the country. For other Acorus species in China, ethnobotanical records are few. During field investigations from 2006 to 2017, we interviewed 573 individuals representing ethnic groups such as the Miao, Yao, Buyi, Shui, Tujia, Dong, She, Maonan, Zhuang, Yi, and Han people. Various ethnobotanical approaches were adopted in the field surveys, including key informant interviews, semistructured interviews, participatory observation, direct observation, etc. The results have revealed a rich treasure trove of traditional knowledge on Acorus in China. Two species (A. macrospadiceus and A. gramineus) were used by ethnic groups as spices to add flavor to meat. Through the study found that all the species of Acorus had medicinal value, especially A. tatarinowii, deafness, blindness, and digestive disorders were among the conditions commonly treated using these plants. Traditional knowledge of the cultural, ethnomedicinal, and food values of Acorus, based on our recent literature surveys and field investigations in China is presented here. A better understanding of Acorus is vital for conserving the plants and the traditional knowledge associated with them.

    Opis:
    Pyrolysis is potentially an effective treatment of oily sludge for oil recovery, and the addition of a catalyst is expected to affect its pyrolysis behavior. In the present study, Fe/Al-pillared bentonite with various Fe/Al ratios as pyrolysis catalyst is prepared and characterized by XRD, N2 adsorption, and NH3-TPD. The integration of Al and Fe in the bentonite interlayers to form pillared clay is evidenced by increase in the basal spacing. As a result, a critical ratio of Fe/Al exists in the Fe/Al-pillared bentonite catalytic pyrolysis for oil recovery from the sludge. The oil yield increases with respect to increase in Fe/Al ratio of catalysts, then decreases with further increasing of Fe/Al ratio. The optimum oil yield using 2.0 wt% of Fe/Al 0.5-pillared bentonite as catalyst attains to 52.46% compared to 29.23% without catalyst addition in the present study. In addition, the addition of Fe/Al-pillared bentonite catalyst also improves the quality of pyrolysis-produced oil and promotes the formation of CH4. Fe/Al-pillared bentonite provides acid center in the inner surface, which is beneficial to the cracking reaction of oil molecules in pyrolysis process. The present work implies that Fe/Al-pillared bentonite as addictive holds great potential in industrial pyrolysis of oily sludge.

    Opis:
    Mycorrhizal mycelium can simultaneously colonize two and more neighboring plants to form common mycelium network (CMNs), whereas the information regarding CMN effects on endogenous signal substances is limited. In this study, a rootbox was separated by 37- or 0.45-μm mesh to establish donor chamber (the presence of roots and hyphae) and receptor (hyphae presented or not, free of roots) chamber, where an arbuscular mycorrhizal (AM) fungus Paraglomus occultum was inoculated into trifoliate orange seedlings of donor chamber to illustrate the underground communications of signal substances by CMNs. Mycorrhizal colonization resulted in better plant growth performance and greater root morphology in donor and receptor plants. AM inoculation increased significantly the root nitric oxide (NO) and calmodulin (CaM) levels of donor plants, regardless of 37- and 0.45-μm mesh, and subsequent CMNs induced higher root NO and CaM levels in receptor plants. Mycorrhizal colonization did not produce significant changes in root zeatin riboside (ZR) levels of donor plants, but CMN hyphae modulated lower root ZR levels of receptor plants. Mycorrhizal inoculation and subsequent CMN hyphae induced lower root gibberellin levels of donor and receptor plants, and only CMN hyphae produced lower root methyl jasmonate concentrations of receptor plants. Our results first reveal the underground communication of CaM, NO, and ZR by CMNs with P. occultum between trifoliate orange seedlings.

    Opis:
    Canine mammary tumors are the most common neoplasms in intact female dogs. The surgery cannot always solve the problem, chemotherapy are recommend to these patients. However, chemotherapy could always fail because of multidrug resistance (MDR). Through stepwise increasing 5-Fluorouracil (5-FU) concentration in the culture medium, a 5-FU-resistant canine mammary tumor cell line CMT7364/5-FU was established to disclose the molecular mechanism of the drug resistance. Cell morphology, cell sensitivity to drugs, growth curves, expression of proteins, and chemo-sensitivity in vivo were compared between the parental cell line and resistant cell line. As compared it to its parental cell line (CMT7364), CMT7364/5-FU showed different morphology, cross-resistant to other chemo-drugs and a prolonged population doubling time (PDT). The drug efflux pump proteins (ABCB1 and ABCG2) in CMT7364/5-FU were up-regulated. In vivo, the similar result revealed that CMT7364/5-FU cell line was more resistant to 5-FU. In conclusion, a 5-FU-resistant canine mammary tumor cell line (CMT7364/5-FU) was successfully established, it can serve as a good model for researching the mechanism of MDR and screening effective agents to reverse drug resistance.

    Opis:
    The near-field multiple optical trapping using high order axially symmetric polarized beams (ASPBs) is studied for the first time. First, a near-field optical trapping scheme is proposed based on the Kretschmann–Raether configuration, and surface plasmon polaritons (SPPs) field distributions excited by incident ASPBs are calculated, which present a multi-focal-spot pattern and the size of spots is much smaller than that of the diffraction limitation. Then, the gradient forces on Rayleigh dielectric particles formed by the multi-focal-spot focused field are computed, which indicates that multiple ultra-small particles with the refractive index higher than that of the ambient medium can be trapped simultaneously on the metal surface. The number and size of trapped particles can be manipulated by flexibly modifying the polarization order of incident beams, which is expected to enhance the capability of traditional optical trapping systems and provide a solution for massively parallel optical trapping of nanometer-sized particles.

    Opis:
    Using a monoenergetic positron beam, annealing study of the Al/n-GaSb system was performed by monitoring the Doppler broadening of the annihilation radiation as a function of the positron implanting energy. The S-parameter against positron energy data was successfully fitted by a three-layer model (Al/interface/GaSb). The annealing out of the open volume defects in the polycrystalline Al layer was revealed by the decrease in the S-parameter and the increase in the effective diffusion length of the Al layer. For the as-deposited samples, a 5 nm interfacial region with S-parameter larger than those of the Al overlayer and the bulk was identified. After the 400ºC annealing, this interfacial region extends to over 40 nm and its S-parameter dramatically drops. This is possibly due to the new phase formation at the interface. Annealing behaviors of S$\text{}_{B}$ and L$\text{}_{+,B}$ of the GaSb bulk showed the annealing out of positron traps (possibly the V$\text{}_{Ga}$-related defect) at 250ºC. However, a further annealing at 400ºC induces the formation of positron traps, which are possibly of another kind of V$\text{}_{Ga}$-related defect and the positron shallow trap GaSb antisite.

    Opis:
    An attempt has been made to selectively oxidise synthetic lignin-like polymer for fine chemicals. The G- and S-type polymers (G- and S- type lignin model polymers) were synthesized using simple aromatic compounds as starting materials and then oxidised to benzaldehydes by reacting them with Co(salen) catalytic system. The reaction was characterized by measuring the change of the polymer with FTIR, C-13 NMR and GC-MS spectroscopy. The results obtained by the FTIR and C-13 NMR showed that the effects of NaOH were important and higher yield of benzaldehydes characterized by GC-MS in the presence of NaOH in the course of catalytic oxidation of the polymer demonstrated these effects. From the results, the catalyst could suitably be used in green procedures for lignin transformation.

    Opis:
    A polarization-independent reflective grating with improved bandwidth is presented based on the mixed metal-dielectric grating. The novel grating is composed of the substrate, the metal slab, two dielectric layers, and the covering layer. The grating parameters are optimized for the special duty cycle of 0.6 at an incident wavelength of 1550 nm used in dense wavelength division multiplexing (DWDM). With the designed grating, high efficiency can be diffracted into the reflective –1st order for both TE and TM polarizations, where the polarization-independence is exhibited. Most importantly, the efficiency of more than 90% can be achieved within the incident wavelength bandwidth of 1262–1686 nm, where the bandwidth is improved greatly compared with the reported surface-relief single-layer grating. The reflective grating can have advantages of high efficiency, polarization-independence, and wide bandwidth, which should be useful for DWDM applications.

    Opis:
    The influences of genetic and environmental factors on the anther culture responses of wheat were investigated. Significant differences for callus induction, plant regeneration, and green plant percentages were observed when the nucleus of Triticum acstivum L. cv. Selkirk was transferred to ten alien cytoplasms by substitution backcrosses. In most cases, the alien cytoplasms decreased anther culture responses, but sometimes they were as good as or better than the T. aestivum cytoplasm. Significant within-genotype variation for anther culture responses were observed for wheat varieties Chris, Yecora Rojo, WA7176 and Edwall, indicating genetic heterogeneity in the present commercial cultivars, and potential for improving anther culture responses by in vitro prescreening. When five genotypes (Chris, Pavon 76, Butte 86, WA6916, and Edwall) were cultured across three (potato-4 liquid, 100 g L⁻¹ ficoll-supplemented, and 6 g L⁻¹ agar-solidified) induction media, the liquid and ficoll-containing media were 10 to 15 times more productive than the agar-solidified medium. Whereas, the ficoll medium was not significantly different from the liquid medium. Several low concentration starch media appeared promising to replace current induction media. The starch media sustained the highcallus-induction properties of the liquid medium, while improving callus aeration similar to that observed on solid media, resulting in markedly higher plant regeneration and green plant percentages.

    Opis:
    Poly(vinyl alcohol) films were prepared with manganous chloride (MnCl2 · 4H2O) and glycerin as complex plasticizer. The micro morphology of pure PVA film and complex plasticizer plasticized PVA films was observed by scanning electron microscope (SEM). The interaction between complex plasticizer and PVA molecules was investigated by Fourier transform infrared spectroscopy (FT-IR). The influence of complex plasticizer on crystalline, thermal and mechanical properties of PVA films was studied by X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TG), and tensile testing, respectively. The results showed that the complex plasticizer of MnCl2 · 4H2O/glycerin could interacted with PVA molecular and then effectively destroy the crystals of PVA. PVA films plasticized with complex plasticizer of MnCl2 · 4H2O/glycerin became soft and ductile, with lower tensile strength and higher elongation at break compared with PVA films. This is an important cause of plasticization of the complex plasticizer of MnCl2 · 4H2O/glycerin on PVA films.

    A model to optimize the planning of the chemical integrated system comprised by multi-devices and multi-products has been proposed in this paper. With the objective to make more profits, the traditional model for optimizing production planning has been proposed. The price of chemicals, the market demand, and the production capacity have been considered as mutative variables, then an improved model in which some parameters are not constant has been developed and a new method to solve the grey linear programming has been proposed. In the grey programming model, the value of credibility can be suggested by the decision-makers, and the results of the production planning calculated by the model can help them to achieve their desired target. An actual case has been studied by the proposed methodology, and the proposed methodology can be popularized to other cases.

    Opis:
    This paper concerns the problem of designing an EID-based robust output-feedback modified repetitive-control system (ROFMRCS) that provides satisfactory aperiodic-disturbance rejection performance for a class of plants with time-varying structured uncertainties. An equivalent-input-disturbance (EID) estimator is added to the ROFMRCS that estimates the influences of all types of disturbances and compensates them. A continuous-discrete two-dimensional model is built to describe the EID-based ROFMRCS that accurately presents the features of repetitive control, thereby enabling the control and learning actions to be preferentially adjusted. A robust stability condition for the closed-loop system is given in terms of a linear matrix inequality. It yields the parameters of the repetitive controller, the output-feedback controller, and the EID-estimator. Finally, a numerical example demonstrates the validity of the method.

    This paper presents an approach to identify apparel silhouettes. A feature region of the human face was first proposed for conducting face detection in fashion pictures with the AdaBoost method, and the head was then located with its positional relation to the facial feature region. The linear relationship between the ratio of the body height to head length and the length of the lower body was ensured by restricting the RBH to a specific range. Under this condition, the apparelled body was divided into several parts, and the boundary of apparel on the lower body was determined considering the influence of the hemline. Based on the widths of the body parts and the apparel on the lower body, shape factors were established to express the extent to which the apparel silhouette approached a certain shape. A computer program was developed for implementation and demonstrated high accuracy in silhouette identification of an appareled body.
    Przedstawiono próbę identyfikacji sylwetki ubranego modelu. Opracowano system właściwości charakteryzujących twarz człowieka dla możliwości dalszego wyodrębnienia twarzy ze zdjęć modeli. Zastosowano metodę AdaBoost. Umożliwiło to usytuowanie głowy w stosunku do innych elementów ubioru. Zidentyfikowano liniowe zależności pomiędzy wysokościami całości sylwetki, jej dolnej części, i głowy. Na tej podstawie ubrana sylwetka człowieka była dzielona na szereg części i określano granice ubioru w stosunku do dolnej części sylwetki, uwzględniając wpływ dolnej krawędzi ubioru. Opierając się na szerokościach poszczególnych części ciała człowieka i ubioru dolnej części sylwetki, ustalono czynniki kształtu dla możliwości kwalifikacji sylwetki do odpowiedniego typu. Opracowano program komputerowy umożliwiający dużą dokładność identyfikacji sylwetki ubranego modelu.

    Opis:
    The impact of transient wind events on an established zooplankton community was observed during a field survey in a coastal region off northern Norway in May 2002. A transient wind event induced a coastal jet/filament intrusion of warm, saline water into our survey area where a semi-permanent eddy was present. There was an abrupt change in zooplankton community structure within 4–7 days of the wind event, with a change in the size structure, an increase in lower size classes less than 1 mm in equivalent spherical diameter (ESD) and a decrease in larger size classes greater than 1.5 mm in ESD. The slope of zooplankton biovolume spectra changed from −0.6 to −0.8, consistent with the size shifting towards smaller size classes. This study shows that even well established zooplankton communities are susceptible to restructuring during transient wind events, and in particular when wind forcing induces horizontal currents or filaments.

    Opis:
    The structural, elastic anisotropy and thermodynamic properties of the I4mm-B₃C are investigated using first-principles calculations and the quasi-harmonic Debye model. The calculated elastic anisotropic suggest that I4mm-B₃C is elastically anisotropic with its Poisson ratio, shear modulus, the Young modulus, the universal anisotropic index, shear anisotropic factors, and the percentage of elastic anisotropy for bulk modulus and shear modulus. The quasi-harmonic Debye model, using a set of total energy versus molar volume obtained with the first-principles calculations, is applied to the study of the thermal and vibrational effects. The thermal expansions, heat capacities, the Grüneisen parameters and the Debye temperatures dependence on the temperature and pressure are obtained in the whole pressure range from 0 to 90 GPa and temperature range from 0 to 2000 K.

    Opis:
    An affine nonlinear autoregressive moving average (NARMA) model is derived from the neural network (NN) based general NARMA model in this paper, by using Taylor series expansion. The predictive error of this affine NARMA model will be quite acceptable, at least for the control purpose, if the amplitude of control input is properly limited. Therefore, an adaptive control scheme based on this model is proposed and applied to the design of adaptive power system stabilizer (APSS) since the amplitude of PSS output is usually well limited. The feature of this control scheme is that the control input can be online analytically obtained. Thus, comparing to the traditional NN based APSS (TAPSS), the affine NARMA model based APSS (AAPSS) does not need the training of a NN as neuro-controller, which may be a troublesome and time consuming step during the design. Moreover, the AAPSS can generally perform better than the TAPSS. Simulation studies on a single machine infinite bus system and a multi-machine system show that the AAPSSs can consistently well perform to damp electromechanical oscillations in the systems over a wide range of operating conditions.

    Opis:
    Maintainability allocation is an important step in product quality design. Traditional allocation methods are limited such that the allocated mean time to repair for each unit design apartment cannot be totally controlled by the corresponding design apartment. This paper proposesa new time characteristics-based maintainability allocation method to solve the aforementioned problem. The relationship between design content and repair time is considered in this method, and repair time is divided into common and individual repair time. Common repair time, which isdetermined by the overall system design,is deducted from the total repair time. Individual repair time is allocated to the specific unit through proper traditional allocation method. A case study is performed,and results demonstrate that the new method is more suitable and effective than original methods in terms ofmaintainability allocation.
    Alokacja obsługiwalności jest ważnym krokiem w projektowaniu jakości produktów. Tradycyjne metody alokacji są ograniczone w takim sensie, że alokowany średni czas do naprawy dla każdego działu projektowania jednostki produktu nie może być całkowicie kontrolowany przez odpowiedni dział projektowania. W niniejszej pracy zaproponowano rozwiązanie tego problemu wykorzystujące nową metodę alokacji obsługiwalności opartą na charakterystykach czasowych. W proponowanej metodzie bierze się pod uwagę związek między zawartością projektu a czasem naprawy, czas naprawy zaś dzieli się na wspólny i indywidualny. Wspólny czas naprawy, który zależy od ogólnej konstrukcji systemu, odejmuje się od całkowitego czasu naprawy. Indywidualny czas naprawy alokuje się do konkretnej jednostki za pomocą odpowiedniej tradycyjnej metody alokacji. W pracy przeprowadzono studium przypadku, którego wyniki pokazują, że nowa metoda jest bardziej odpowiednia i skuteczna jeśli chodzi o alokację obsługiwalności niż metodystosowane pierwotnie.

    Opis:
    A mathematical model for the yarn count of ring-spun slub yarn was established to predict the yarn profile based on process parameters such as the fibre length, the velocities of rollers and the time of over-feeding. The theoretical study shows that the slub length depends mostly on the process parameters above. The actual slub length is a fibre length greater than the slub length designed, and the actual length of basic yarn is a fibre length less than the length of basic yarn designed. The validity of the model was then verified using four sets of experiments. The experimental results agreed well with the model predictions and showed that the present model had high prediction accuracy, which may aid in the design and production of a desired slub yarn with controlling spinning parameters.
    Model matematyczny masy liniowej przędzy obrączkowej typu slub został wyznaczony w celu określenia geometrii przędzy na podstawie parametrów procesu, takich jak długość włókien, prędkości rolek i wielkości naddatku. Badania teoretyczne wskazują, że długość odcinków przędzy typu slub zależy głównie od powyżej wymienionych parametrów procesu. W artykule podano właściwości zależności teoretycznych i rzeczywistych dla przędzy fantazyjnej. Prawidłowość tego modelu została następnie poddana weryfikacji przy użyciu cztery zestawów eksperymentalnych o zróżnicowanych warunkach. Wyniki badań eksperymentalnych potwierdziły przewidywania modelu i pokazały, że obecny model zapewnia wysoką dokładność przewidywania i dzięki temu ułatwia projektowanie i produkcję określonych włókien fantazyjnych.

    Opis:
    The combined effect of sulfur (S) and acid soluble aluminum (Als ) content on precipitates and microstructures in grain-oriented silicon steel were investigated. The results show that there are dominant AlN and a little amount of MnS-AlN composite in annealed hot-rolled band, and the amount of precipitates increases distinctly with increasing Als content, while S content plays a negligible role. The inhibitors that precipitate during hot band annealing can restrain the grain growth during hot band annealing and primary annealing, and the smaller grains of annealed hot-rolled band can contribute to the formation of {111} <112> texture during primary annealing. Lower S content is conducive to the formation of {111} <112> texture during primary annealing by promoting the formation of Goss texture during hot rolling.

    Opis:
    As an important quality characteristic, maintainability is the ability of a product to be repaired efficiently and economically. Because it is mainly determined at the design stage, maintainability is mostly affected by the construction of a product. Traditional product design methods put more focus on design for function and production, neglecting design for maintainability, which causes a gap between functional construction design and maintainability design. The delay of maintainability design results in huge costs for design changes and even irrevocable design flaws. Because of the weak relationship between functional construction and maintainability in product design, the influence of maintainability design on the product is limited. To resolve this problem, this paper proposes a design approach considering the relationship between maintainability and functional construction. First, maintainability design factors (MDFs) and functional construction design factors (FCDFs) are defined and classified. Second, based on topology graphic theory, a correlative relationship model is constructed by graphically combining the MDFs and FCDFs into a network diagram. Third, to determine primary design factors, a quantization matrix is developed to perform importance evaluation of the correlative relationship. Finally, a practical case is studied by implementing the proposed approach for the lubrication system of an armoured vehicle. The results validate the effectiveness and feasibility of the approach.
    Konserwowalność to ważna charakterystyka jakościowa, którą można zdefiniować jako możliwość wydajnej i ekonomicznej naprawy produktu. Ponieważ o konserwowalności produktu decydują głównie wybory dokonane na etapie projektowania, największy wpływ na nią ma budowa produktu. Tradycyjne metody projektowania produktów kładą większy nacisk na projektowanie funkcji i produkcji, zaniedbując projektowanie pod kątem łatwości konserwacji, co powoduje powstanie luki między projektowaniem funkcjonalnej budowy produktu a projektowaniem jego konserwowalności. Opóźnienie etapu projektowania konserwowalności generuje ogromne koszty związane z koniecznością zmian projektu i może nawet prowadzić do nieodwracalnych wad projektowych. Ze względu na słabą zależność między budową funkcjonalną a konserwowalnością w projektowaniu produktu, wpływ projektowania konserwowalności na produkt jest ograniczony. Aby rozwiązać ten problem, w niniejszej pracy zaproponowano podejście projektowe uwzględniające związek między konserwowalnością a budową funkcjonalną wyrobu. Po pierwsze, zdefiniowano i sklasyfikowano czynniki konstrukcyjne (projektowe) dotyczące konserwowalności (MDF) oraz czynniki konstrukcyjne związane z budową funkcjonalną produktu (FCDF). Po drugie, w oparciu o teorię graficznej reprezentacji topologii, zbudowano model zależności korelacyjnych między MDF i FCDF w postaci diagramu sieciowego. Po trzecie, w celu określenia podstawowych czynników konstrukcyjnych, opracowano macierz kwantyzacji, pozwalającą na ocenę ważności relacji korelacyjnych. Wreszcie, przeanalizowano przypadek układu smarowania pojazdu opancerzonego jako przykład zastosowania proponowanego podejścia w praktyce. Wyniki potwierdzają skuteczność omawianego podejścia oraz możliwość jego praktycznego wykorzystania.

    Opis:
    In order to study the characteristics of mixed vessel traffic flow, based on classical head distance model and probability analysis, by studying the combination time head way of different vessel-following sequences, the capacity model of mixed vessels traffic flow was established. Through analyzing two representative types of vessels, research results indicate that the capacity of mixed traffic increase with the traffic flow speed in a certain speed range, but the increasing trend slow down. The closer length and inertial stopping distance of different kind vessels are, the more capacity of mixed traffic increases. And the influence of reaction time on the capacity is related to proportion of different kind vessels.

    Opis:
    The degradation of flutriafol in aqueous persulfate (S2O82–) system in the presence of selected transition metal ions was investigated. In the presence of Ag+ or Fe2+, flutriafol degradation occurs, whereas in the presence of Mn2+, Co2+, Ni2+, Cu2+, Zn2+ and Bi3+ ions, the degradation is less than 15%. The Ag+/ S2O82– aqueous system being the most effective was adopted for experimental and theoretical investigations. It was confirmed that pH of 3.0 is the most suitable, and that both · SO4–and ·OH– radicals are the main active species to afford flutriafol degradation, with the former contributes more than the latter. To elucidate degradation mechanism, molecular orbital calculations were performed and reaction intermediates identified by GC/MS and HPLC/MS/MS analyses. Three degradation pathways are proposed that involve the cleavage of C–N and C–C bonds as a result of ·SO4– attack, as well as the formation of hydroxylated products due to · OH radicals.

    Opis:
    Rare earth elements (REEs) provide important properties to clean energy technologies such as wind turbine and hybrid electric vehicles. The global REE demand will grow rapidly during the global transformation toward a greener economy in the next decades. This high demand will require a steady supply chain in the long run. China has a monopoly of global REE production and extraction. The global REE supply chain runs the risk of disruption along with Chinese REE policy evolution. To overcome this supply chain vulnerability, new strategies and measures should be adopted to satisfy future REE supply/demand. There is a pressing need to explore REE deposits, develop efficient REE recycling techniques from end-of-life products, improve substitution technologies for REEs, and reduce the number of critical REEs used in devices. Such measures are facing significant challenges due to environmental factors and an unbalanced market, and overcoming them requires efforts from government and REE companies.
    Pierwiastki ziem rzadkich (Rare Earths Elements) mają istotne znaczenie dla rozwoju czystych technologii energetycznych, takich jak turbiny wiatrowe czy pojazdy hybrydowe. Światowy popyt na REE będzie wzrastał w związku z globalną transformacją w kierunku bardziej czystej (ekologicznej) gospodarki w okresie najbliższych dziesięcioleci. Wysoki popyt wymagać będzie stabilnego łańcucha dostaw REE w dłuższej perspektywie. Chiny mają monopol w zakresie globalnej produkcji i wydobycia REE. Światowe dostawy REE obarczone są jednak ryzykiem zakłóceń wynikających z chińskiej polityki w tym zakresie. W związku z tym, powinny być przyjęte nowe środki i strategie w celu zaspokojenia przyszłego popytu/podaży na REE. Istnieje pilna konieczność: poszukiwania nowych złóż, opracowania skutecznych technik recyklingu z wycofanych z eksploatacji produktów, poprawy technologii z zastosowaniem substytutów REE oraz zmniejszenie liczby krytycznych pierwiastków ziem rzadkich w stosowanych urządzeniach. Działania te stanowią poważne wyzwanie ze względu na czynniki środowiskowe i niezrównoważony rynek (monopol podaży). Przezwyciężenie ich wymaga odpowiednich działań ze strony rządu i firm zajmujących się produkcją REE.

    Opis:
    Automated detect detection in woven fabrics for quality control is still a challenging novelty detection problem. This work presents five novel fractal features based on the box-counting dimension to address the novelty detection of fabric defect. Making use of the formation of woven fabric, the fractal features are extracted in a one-dimension series obtained by projecting a fabric image along the warp and weft directions, where their complementarity in discriminating defects is taken into account. Furthermore a new novelty detector based on fuzzy c-means (FCM) is devised to deal with one-class classification of the features extracted. Finally, by jointly applying the features proposed and the FCM based novelty detector, we evaluate the method proposed for eight datasets with different defects and textures, where satisfying results are achieved with a low overall missing detection rate.

Poprzez wspólne zastosowanie proponowanych cech i opartego na FCM detektorze sprawdzono proponowaną metodę dla ośmiu zestawów danych z różnymi defektami i teksturami. Stwierdzono, że otrzymane wyniki są na satysfakcjonującym poziomie.

    Opis:
    The thermal damage in octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) based plastic-bonded explosive (PBX) was investigated using in situ small-angle neutron and X-ray scattering techniques. The microstructural evolution was quantitatively characterized by the model fitting parameters of total interfacial surface area (Sv) and void volume distribution. The Sv of HMX-PBX decreased markedly above 100 °C, indicating the movement of binder into the voids. After subsequent cooling to room temperature, the scattering intensity increased significantly with increasing storage time, and a new population of voids with average diameter of 20 nm was observed, accompanied by the gradual phase transition of HMX from δ- to β-phase. The experimental results implied that serious damage within the HMX-PBX was developed during storage after heating.

    Opis:
    A water-soluble chitosan derivative N-[(2-hydroxy-3-trimethylammonium)propyl] chitosan chloride (HTCC) was prepared and used for the modification of soybean protein/poly (vinyl alcohol) blend fiber (SPF). The dying properties of modified SPF with Cibacron FN series reactive dyes were discussed in relation to a salt-free and alkaline/acidic denaturalization dyeing bath (green dyeing process). Results showed that dye exhaustion in the green dyeing process was obviously higher than that in the conventional dyeing process, despite the addition of a large amount salt in the latter case. However, the washing fastness of SPF treated with HTCC in the green dyeing process was inferior to that of untreated SPF in the conventional dyeing process. COD (chemical oxygen demand) values of the green dyeing process effluent were found to be decreased compared with conventional dyeing effluent, which indicated that the green dyeing process could decrease the amount of toxicity of dyeing effluent remarkably.
    Przygotowano rozpuszczalną w wodzie mieszankę pochodnej chitozanu - chlorek N-[(2-hydroksy-3-trimetyloamono)propylo] chitozanu (HTCC). Zastosowano ją dla modyfikacji mieszanki sojowych włókien proteinowych z PVA. Następnie badano właściwości barwienia zmodyfikowanych włókien za pomocą barwników reaktywnych Cibacron seria FN zastosowanych w kąpieli bezsolnej i zasadowo/kwasowej denaturalizacyjnej kąpieli (ekologiczny proces barwienia). Wyniki wskazały, że wyczerpanie barwnika w procesie ekologicznego barwienia było zasadniczo wyższe niż to przy barwieniu konwencjonalnym, niezależnie od dodatku dużej ilości soli w tym ostatnim. Jednakże odporność na pranie włókien barwionych w procesie ekologicznym była niższa w stosunku do procesu konwencjonalnego. Stwierdzono że wartość COD (chemiczne zapotrzebowanie tlenu) w przypadku ścieków z ekologicznego barwienia była niższa w porównaniu do ścieków z barwienia konwencjonalnego, co wskazuje, że proces ekologicznego barwienia może w znacznym stopniu zmniejszyć toksyczność ścieków.

    Opis:
    The paper has as an objective to combine and disseminate a brief knowledge on generators and power electronics for Wave Dragon MW (WDMW) Power Take Off system. Wave Dragon MW captures power from sea waves by means of low-head turbines and converts it into rotating mechanical power. In recent years because of energy saving problem on almost whole world power electronics and electric machines as well as renewable energy market has been intensively developed. Problems which can appear in conversion mechanical power to electrical power in WDMW can be expected to be similar as in wind turbine. Therefore, state of the art briefly can base on state of the art for wind turbines. However, subject of the mechanical energy conversion from sea waves to electrical energy is not well identified and further research should be curried out.
    Artykuł ma na celu zebranie i przedstawienie podstawowych informacji na temat przekształtnika energii fal morskich Wave Dragon MW (WDMW). Ponadto również wstępne wyniki symulacyjne zespołu generator-przekształtnik energoelektroniczny - sieć.
