Design and analysis of single-phase five-level inverter based on integrated energy system
Authors: Chen Keyao 
Published: December 2023

Abstract
New energy power generation, mainly photovoltaic power generation and wind power generation, is one of the key research topics today. It is found that the grid-connected phase of power transmission is very important in the transmission process after power generation through these two ways. This paper introduces in detail the various stages of power transmission under the background of integrated energy system, mainly photovoltaic power generation and wind power generation as the research object. This paper presents a new grid-connected symmetrical cascade half-bridge multilevel inverter (SCHB) under the background of comprehensive energy and presents a Pulse Width Modulation (PWM) control scheme which can make the inverter output stable multilevel voltage. By this scheme, the voltage of the shunt capacitor is basically unchanged and the multistage voltage output of SCHB inverter is guaranteed. The advantages of the designed inverter are that the whole inverter can be powered by a single power supply and a single inductance, and the number of voltage levels can be controlled because of the use of a small amount of reactive power components. This paper describes the topological results of the inverter and the PWM control scheme of stable output multistage voltage.

Published: December 2023

Abstract
In view of the limitations of traditional maintenance methods for rail vehicles, this study proposes a data-driven maintenance system for critical parts of rail vehicles based on a cloud-side collaborative framework. Currently, there are several major issues with the maintenance of critical parts of rail vehicles, including long maintenance cycles, difficult troubleshooting, high maintenance costs, low maintenance efficiency, irregularities in data management, and a low level of informatization. To address these problems, a cloud-edge collaboration approach is adopted. The maintenance information of the vehicles is synchronized and exchanged in real-time with the cloud data center. Sensor and Internet of Things (IoT) technologies are used to collect real-time operational and status data of rail vehicles. The data is then analyzed and modelled in the cloud data center. The system achieves fault prediction and remaining useful life prediction for key components of the rail vehicles by applying machine learning algorithms. The experimental results demonstrate that compared to traditional maintenance methods, the system enables more effective troubleshooting and remaining useful life prediction of critical components of the vehicles. It improves maintenance efficiency and safety while also offering practical application value.

Authors: Peng Ziming , Wang Zhi , Zhang Wenqi 
Published: December 2023

Abstract
With the progress of urban transportation infrastructure and the construction of intelligent transportation system, sufficiently accurate traffic flow prediction is of increasing importance for urban planning and management. This paper based on traffic flow data in a section of highway in Los Angeles, USA, we combine external qualitative data such as weather and work calendars, analyze and process the factors significantly influencing traffic flow first, then train and test the traffic flow data by building machine learning Support Vector Regression (SVR) model and the Back Propagation neural network (BP neural network). The test results show that the BP neural network traffic flow prediction model incorporating the external environment is more accurate, and that the external environment has a significant impact on the traffic flow prediction problem. If more significantly influencing factors can be taken into account, or if the current algorithm can be optimized, the prediction accuracy will have further improved, thus effectively enhancing the efficiency and safety of traffic systems.

The Effect of Conductive Agent on the Cycle Behavior of Zinc-ion Batteries: Based on In Situ Characterization
Authors: Pan Yete , Bao Cheng 
Published: December 2023

Abstract
This study investigates the effect of Super P as a conductive additive on the electrochemical impedance spectroscopy (EIS) of zinc-ion batteries (ZIBs). EIS measurements were performed on batteries with different Super P contents, and the results reveal that the initial impedance of the batteries does not have a significant difference. However, after cycling the batteries, the impedance behavior changes significantly. The study finds that a high Super P content results in good stability of the battery, whereas a low content results in poor reversibility of the by-products.

Abstract
In this study, we investigated the electrochemical behavior of MnO2 cathodes in zinc-ion batteries (ZIBs) using in-situ electrochemical impedance spectroscopy (EIS) analysis during cycling. Our results show that the impedance of the MnO2 cathode increases irreversibly during cycling, which is attributed to the generation of by-products at the cathode surface.
Study on the structure and properties of non-water reacted polyurethane grouting materials
Authors: Li Yi , Zhou Jianwei , Chen Baojun , Yang Wen 
Published: December 2023

Abstract
In this study, non-water reacted polyurethane grouting materials were prepared using three different molecular chain lengths of polyether polyols. The influence of polyols and -NCO/-OH index (Rx) on the initial viscosity, mechanical properties, and concrete adhesion performance was investigated. Additionally, the damping performance of the cured materials was evaluated using dynamic mechanical analysis (DMA). The research results showed that with an increase in the molecular chain length of the polyether polyols, the strength of the cured material significantly decreased, while the elongation at break increased noticeably. Compared to the molecular chain length of the polyether polyols, the effect of the Rx on the mechanical properties of the cured material was not significant, especially in the low molecular weight polyether polyol system with shorter molecular chains (G3). The adhesion strength of the non-water reacted polyurethane grouting materials to concrete was highly correlated with the gelation time, and a slow gelation time could result in the formation of foam-like structures and reduce the adhesion strength. Grouting materials with shorter molecular chain lengths combined with low Rx (G3-1.0) or medium molecular chain lengths combined with moderate Rx (G5-1.4) exhibited excellent mechanical and damping properties.
Effects of using collagen and aloe vera grafted fibroin scaffolds on osteogenic differentiation of rat bone marrow mesenchymal stem cells in SBF-enriched cell culture medium
Authors: Taher Mohamed Salma A , Emin Nuray 
Published: December 2023

Abstract
In the study, collagen and aloe vera were grafted onto silk fibroin with two different methods, and 3D-microporous scaffolds (1F5C4A1 and 2F5C4A1) were formed by lyophilization. Three osteogenic cultures were started by seeding rat bone marrow mesenchymal stem cells (MSCs) and pre-induced MSC (osteoblast (OB)) on biopolymeric scaffolds. The osteogenic medium was enriched with 10% (v/v) simulated body fluid (SBF) to promote mineralization and osteogenic differentiation in one of the MSC cultures and the OB culture. X-ray diffraction (XRD), scanning electron microscopy (SEM), scanning electron microscopy- energy dispersive spectrum (SEM-EDS) analyses on cellular samples and histochemical (alizarin red, safranin-O, alcian blue) and immunohistochemical (anti-collagen-1, anti-osteocalcin, anti-osteopontin) staining showed that bone-like mineralization was occurred by both chemically and cellular activity. In addition, pre-osteogenic induction of MSCs in 2D-cultured was found to promote osteogenesis more rapidly when started 3D-cultured. These results indicated that enrichment of the cell culture medium with SBF is sufficient for in vitro mineralization rather than using high concentrations of SBF. The findings showed that OB cells on the 2F5C4A1 scaffold obtained the best osteogenic activity. Still, other culture media with 10% SBF content could be used for bone tissue engineering under osteogenic induction.

Abstract
The horseshoe area of East Java is an area that has abundant natural resource potential. In the northern part of the horseshoe region there is a very good biological natural resource with the potential to be used as a food source. Meanwhile, in the southern part is rich with biological and mining potential. This potential causes changes in land use in the northern and southern regions which can trigger landslides in the Horseshoe area. Changes in land use that change the topography and vegetation to become steep and barren will have a very significant impact on landslides. This study aims to map and predict areas affected by erosions using environmental and physical data using Geographic Information System (GIS) Analysis. The results of the mapping are areas that have threats and are vulnerable as well as capacity to erosion. Based on the results of the mapping, it shows that the index of threats greatly influences the hazard of landslides that occur in the area. Based on the result of the mapping, it shows that the disaster mitigation and adaptation strategy is to reduce the threat index or very high vulnerabilities that affect the risk of landslides that occur in an area.

Abstract
Urban development has always brought some impacts to the existing settlements’ dynamic. Heritage settlements acted as a resilient effort in adapting urban developments. Based on the archipelago’s potential wealth in ethnic diversities and cultural communities, the heterogeneity of urban society has always existed. Ethnic settlements (such as Chinese) are often found in developing countries. The unique characteristics of Chinese ethnic settlements set them apart from other ethnic settlements in the same city (such as Arab, Javanese, and others) in terms of their physical environment and community activities. The values of local wisdom in Chinese ethnic settlements in Chinatown Area of Malang were explored and compared to Kembang Jepun area of Surabaya, using typology as an approach in data analysis and processing. Urban design elements such as land use, style, building functions, accessibility, circulation, public space, green space, signage and conservation areas were discussed in this study context of urban heritage. The aim of the study was to be the future guidelines to the government in directing special ethnic settlements’ arrangement (especially Chinese) along with the characters, as well as providing theoretical input for academics to strengthen the local characters with relatively different ethnic settlements in various cities of archipelago. This study showed that Chinese architecture tolerate, adapt and maintain physical aspects through buildings and the living culture.

Abstract
An urban area offers a wide range of indoor and outdoor activities. The pedestrian area on Kyai Tapa Street, Grogol includes a community-used pedestrian path. It can become an open space in the pedestrian area that serves as a means of enhancing and facilitating activities for the community, particularly pedestrians. The phenomenon on the Kyai Tapa Street, Grogol pedestrian path requires a more explicit concept in the design, so the existing pedestrian path cannot improve the visual quality. It cannot be a comfortable place for pedestrians to pass. Therefore, identifying and evaluating the existing pedestrian path design concepts is necessary. This research study aimed to identify and evaluate the concept of pedestrian paths following the existing conditions using primary and secondary data collection methods through observation, surveys, and literature studies. Factors supporting the comfort of pedestrians are related to the suitability of the path’s shape, the dimensionally design concept, and the elements built around the pedestrian path. The pedestrian path on Kyai Tapa Street, Grogol becomes a link between several places around the pedestrian path area. Therefore, it is necessary to make a clear design concept for pedestrian paths so that the pedestrian path area can improve visual quality and become a comfortable facility for pedestrians.
