Research on Fault Diagnosis of Hydraulic System of Fast Erecting Device Based on Fuzzy Neural Network

In order to improve the fault diagnosis effectiveness of hydraulic system in erecting devices, the fuzzy neural neural network is applied to carry out fault diagnosis of hydraulic system. Firstly, the main faults of hydraulic system of erecting mechanism are summarized. The main faults of hydraulic system of erecting devices concludes abnormal noise, high temperature of hydraulic oil of hydraulic system, leakage of hydraulic system, low operating speed of hydraulic system, and the characteristics of different faults are analyzed. Secondly, basic theory of fuzzy neural network is studied, and the framework of fuzzy neural network is designed. The inputting layer, fuzzy layer, fuzzy relation layer, relationship layer after fuzzy operation and outputting layer of fuzzy neural network are designed, and the corresponding mathematical models are confirmed. The analysis procedure of fuzzy neural network is established. Thirdly, simulation analysis is carried out for a hydraulic system in erecting device, the BP neural network reaches convergence after 600 times iterations, and the fuzzy neural network reaches convergence after 400 times iterations, fuzzy neural network can obtain higher accuracy than BP neural network, and running time of fuzzy neural network is less than that of BP neural network, therefore, simulation results show that the fuzzy neural network can effectively improve the fault diagnosis efficiency and precision. Therefore, the fuzzy neural network is reliable for fault diagnosis of hydraulic system in erecting devices, which has higher fault diagnosis effect, which can provide the theory basis for healthy detection of hydraulic system in erecting devices.

The Image of Woman in the Sintren and Kuda Kepang Arts: Gender Reality and Aesthetic Exploration

The image of women that is actualized through the construction of gender roles, positions, and adaptation processes in artistic expression through Sintren and Kuda Kepang performances is very different. In this regard, the research aims to: (1) explain the forms of art performances of Sintren and Kuda Kepang; and (2) explain the image of women in the art performances of Sintren and Kuda Kepang in the context of gender reality and aesthetic exploration. The research was conducted on the art of Sintren Ujung Gede in Pemalang Regency and Kuda Kepang Turonggoseto in Semarang Regency. The research data were collected using the techniques of (1) observation, (2) interviews, and (3) document studies. The validity of the research data was carried out using the confirmability technique. The study used an interactive model analysis procedure, which was carried out with the stages of data collection, data reduction, data classification, and drawing conclusions. The results show that: (1) Sintren and Kuda Kepang arts are forms of traditional folk-art performances in which there is a scene of trance. This art is usually performed on stage or open arena by involving women as players; (2) The presence of women in the Sintren performances is a requirement that traditionally must be fulfilled until now. On the other hand, in the Kuda Kepang performances, the presence of women is a new phenomenon that provides opportunities and freedom for women to express themselves through dance. In the Sintren performance, the position of women becomes the center, subject, and object during the performance process. As a result, changes in the function of arts often result in the exploitation of Sintren dancers. On the other hand, in the Kuda Kepang art, the involvement of women with all their adaptations provides a new space for resistance to the existing gender stereotypes.

ASYMPTOTIC METHODS OF ANALYSIS IN ELECTRODYNAMICS

Рассматривается метод геометрической дифракции и физической оптики, который является одним из самых точных и эффективных для решения крупных электродинамических задач. Для анализа характеристик процесса приводится его математическое описание, а также для сравнения с ним приведено описание метода конечного интегрирования, который является наиболее популярным и эффективным для малых объектов. Так показано, что применение метода МКИ невозможно для крупных объектов, так как в процессе сеточного разбиения происходит создание слишком большого числа ячеек для расчета, что значительно усложняет процедуру анализа. Для оценки эффективности и точности метода было произведено моделирование антенного элемента, который установлен на корабле-носителе. Так, характеристики излучателя рассчитывались с использованием метода конечного интегрирования, после чего характеристики диаграмм направленности передавались в проект с кораблем, затем производилось моделирование с использованием метода SBR. Итоговые результаты моделирования показали высокую эффективность и точность метода, а возможность установки шага сканирования позволяет управлять временем моделирования, однако стоит учитывать, что слишком большой шаг приводит к снижению точности анализа The article discusses the method of geometric diffraction and physical optics, which is one of the most accurate and effective for solving large electrodynamic problems. To analyze the characteristics of the process, we give its mathematical description and, for comparison, a description of the final integration method, which is the most popular and effective for small objects. Thus, we show that the application of the MCI method is impossible for large objects since in the process of grid division, too many cells are created for the calculation, which significantly complicates the analysis procedure. To assess the effectiveness and accuracy of the method, we simulated the antenna element, which is installed on the carrier ship. We calculated the characteristics of the emitter using the method of finite integration, after which we transferred the characteristics of the radiation patterns to the project with the ship, then we carried out the simulation using the SBR method. The final results of modeling showed high efficiency and accuracy of the method, and the ability to set the scanning step allows you to control the simulation time, however, it should be borne in mind that too large a step leads to a decrease in the accuracy of the analysis.

Lipid profile migration during the tilapia muscle steaming process revealed by a transactional analysis between MS data and lipidomics data

In this work, lipid profile migration from muscle to juice during the tilapia muscle steaming process was revealed by a transactional analysis of data from ultra-high-performance liquid chromatography coupled with Q Exactive (UHPLC-QE) Orbitrap mass spectrometry (MS) and lipidomics. Firstly, the lipids in tilapia muscles and juices at different steaming time points were extracted and examined by UHPLC-QE Orbitrap mass spectrometry. Secondly, a transactional analysis procedure was developed to analyze the data from UHPLC-QE Orbitrap MS and lipidomics. Finally, the corrected lipidomics data and the normalized MS data were used for lipid migration analysis. The results suggested that the transactional analysis procedure was efficient to significantly decrease UHPLC-QE Orbitrap MS workloads and delete the false-positive data (22.4–36.7%) in lipidomics data, which compensated the disadvantages of the current lipidomics method. The lipid changes could be disappearance, full migration into juice, appearance in juice, appearance in muscle, appearance in both muscle and juice, and retention in the muscle. Moreover, the results showed 9 (compared with 52), 5 (compared with 116), and 10 (compared with 178) of lipid class (compared with individual lipid) variables showed significant differences among the different steaming times (0, 10, 30, and 60 min) in all the muscles, juices, and muscle-juice systems, respectively. These results showed significant lipid profile migration from muscle to juice during the tilapia steaming process.

Us & Them: Being at a Residential School, Perspectives from Students, Staff and Whanau

<p>Residential special education for students with diverse learning needs continues to be one of the most complex and contested areas on the education spectrum. This thesis explores a live-in boarding school for girls with special learning, social, emotional, and behavioural needs. The participants view was sought to understand the value placed on the school by those who use and provide the services. The methodological approach was a case study design underpinned by a constructivist paradigm. Twelve participants volunteered to be interviewed. The participants were made up from three stakeholder groups these were teachers, residential workers, students‟ and parents/whānau. An inductive content analysis procedure was used to identity four overarching themes. Overall, all stakeholders thought the school served a purpose and they strongly support a continuum of services, including special residential schools. However, there is clearly a stigma attached to the school, which seems to be a barrier to the school operating in a more inclusive way. This setting the participants believed was more inclusive for the girls as they did not experience the marginalization of the mainstream.</p>
