Yujun Ma,Qi Guo KOREA INSTITUTE FOR HUMANITIES AND SOCIAL SCIENCES 2024 Journal of Arts and Cultural Studies(ACS) Vol.3 No.1

Bainayi is a Chinese garment made of scraps of fabric spliced together. Its history is 1,000 years old and still widely used today. Because of its practicality, in the development of thousands of years, immersed in the Chinese folk culture, it has long carried too much far beyond its function of the profound heritage and cultural connotation. Therefore, today's fashion field also has a wide range of applications. Purpose:This paper discusses the meaning and history of Bainayi, analyzes its cultural connotation from national wisdom, innovative spirit, and life attitude aspects, and discusses the various possibilities of inheritance and application in current fashion design. Methods: The literature on Bainayi is analyzed. The splicing art in Bainayi was defined and summarized to support the research. The effect of the splicing art in different fabrics is analyzed through comparative analysis. Also, the diversity of splicing art in the clothing design is analyzed. Finally, through a case study, this paper conducts an in-depth study on the artwork of splicing, and analyzes art’s the common meaning, aesthetics, and design methods to provide experience for future research. Results: Through analyzing the application of splicing art, the designer presents unique designs and aesthetic ideas by using different colors, structures, and fabrics. The designs have a distinctive splicing art clothing style that enhances its artistic sense and practicality. It breaks the monotonous and boring fabric and creates a unique visual effect. Conclusion: The splicing art of Bainayi combined with today's clothing culture, the meeting point of the splicing art in modern clothing design is excavated, and the rules are summarized to guide practice. Splicing art is also the public's demand for clothing, personality, fashion, and other aspects. Throughout domestic and foreign fashion shows and press conferences, splicing art has become the mainstream trend in fashion design and has great design potential.

Anti-resonant hollow-core photonic crystal fiber (AR-HCF) has unique advantages, such as low nonlinearity and high damage threshold, which make it a promising candidate for high-power laser delivery at distances of tens of meters. However, due to the special structure, optical properties such as modefield profile and bending loss of hollow-core fibers are different from those of solid-core fibers. These differences have limited the widespread use of AR-HCF in practice. In this paper we conduct numerical analysis of AR-HCFs with different structural parameters, to analyze their influences on an AR-HCF’soptical properties. The simulation results show that with a 23-μm air-core diameter, the fundamentalmode profile of an AR-HCF can well match that of the widely used Nufern’s 20/400 fiber, for nearlysingle-mode power delivery applications. Moreover, with the ratio of cladding capillary diameter to aircore diameter ranging from 0.6 to 0.7, the AR-HCF shows excellent optical characteristics, including low bending sensitivity while maintaining single-mode transmission at the same time. We believe these results lay the foundation for the application of AR-HCFs in the power delivery of high power fiber laser systems.

3.2-kW 9.7-GHz Polarization-maintaining Narrow-linewidth All-fiber Amplifier

Hang Liu,Yujun Feng,Xiaobo Yang,Yao Wang,Hongming Yu,Jue Wang,Wanjing Peng,Yanshan Wang,Yinhong Sun,Yi Ma,Qingsong Gao,Chun Tang 한국광학회 2024 Current Optics and Photonics Vol.8 No.1

We present a Yb-doped narrow-linewidth polarization-maintaining (PM) all-fiber amplifier that achieves a high mode-instability (MI) threshold, high output power, and 9.7-GHz spectral linewidth. Six wavelength-multiplexed laser diodes are used to pump this amplifier. First, we construct a high-power fiber amplifier based on a master oscillator-power amplifier (MOPA) configuration for experiments. Subsequently, we examine the MI threshold by individually pumping the amplifier with wavelengths of 976, 974, 981, 974, and 981 nm respectively. The experimental results demonstrate that the amplifier exhibits a high MI threshold (>3.5 kW) when pumped with a combination of wavelengths at 974 and 981 nm. Afterward, we inject an optimized phase-modulated seed with a nearly flat-top spectrum into this amplifier. Ultimately, laser output of 3.2 kW and 9.7 GHz are obtained.

Chen, Min,Ma, Yujun,Li, Yong,Wu, Di,Zhang, Yin,Youn, Chan-Hyun Institute of Electrical and Electronics Engineers 2017 IEEE communications magazine Vol.55 No.1

<P>With the rapid development of the Internet of Things, cloud computing, and big data, more comprehensive and powerful applications become available. Meanwhile, people pay more attention to higher QoE and QoS in a 'terminal-cloud' integrated system. Specifically, both advanced terminal technologies (e.g., smart clothing) and advanced cloud technologies (e.g., big data analytics and cognitive computing in clouds) are expected to provide people with more reliable and intelligent services. Therefore, in this article we propose a Wearable 2.0 healthcare system to improve QoE and QoS of the next generation healthcare system. In the proposed system, washable smart clothing, which consists of sensors, electrodes, and wires, is the critical component to collect users' physiological data and receive the analysis results of users' health and emotional status provided by cloud-based machine intelligence.</P>

Competitive MAC protocols become a good choice for Wireless Sensor Network because of their have good dynamic adaptability and so on. However, in general, there is a serious problem of data collision in competitive protocols, so a low collision MAC protocol based on broadcast messages is proposed in this paper, SA-MAC (Self-adaption Advertisement MAC). It uses broadcast messages to make the related nodes working in a scheduled time slot, while the unrelated nodes turning to sleep in the time slot, thus reducing the probability of data collision. Additionally, it designs the corresponding adaptive contention window mechanism and fast transmission mechanism according to the usage ratio of data buffer, so the network performance is further improved. The simulation results show that, compared with S-MAC and ADV-MAC, SA-MAC can reduce the energy consumption and delay while improving the packet delivery ratio. Moreover, it maintains a good network performance whether in the single-hop or multi-hop network environment.

Energy efficiency is one of the primary performance parametersin wireless sensor network (WSN). The data collected by neighboring nodesin the high density WSN tend to have a high correlation which isdirectly transmitted to the sink node (DGN) will seriously reduce the energy efficiency of wireless sensor networks.For improving the energy efficiency of high node density WSN, We introduce distributed source coding (DSC) which can compress the high correlation source data into WSNbased on virtual MIMO. In the simulationresults indicate thatDSC can effectively reduce the energy consumption in data transmission and improve the energy efficiencyof the whole WSN.

Yi Li,Junhao Sun,Jie Wei,Chao Mu,Yujun Zhao,Shengping Wang,Xinbin Ma 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.111 No.-

ZSM-22 with one-dimensional straight channels and suitable acid properties is widely applied in theselective hydrocracking of long-chain alkanes to produce middle distillate. In this work, the tandem catalystswith two kinds of modified ZSM-22 were employed in series to optimize the distribution of theproduct in the hydrotreatment of n-C16 to produce jet fuel. The yield of linear alkanes with high carbonnumbers was enhanced over the upstream catalyst bed of Pt/L-HZSM-22 with shielded external acid siteswhile the isomerization with less further cracking occurred over the downstream catalyst bed of Pt/Me-HZSM-22 with introduced mesopores. The tandem catalysts can combine the ability of Pt/L-HZSM-22 toproduce heavy n-alkanes and the stronger isomerization performance of Pt/Me-HZSM-22. The highestyield of jet fuel (23 wt.%) can be obtained over the tandem catalysts instead of any individual catalyst. The strategy of the tandem zeolite has been initially verified and proposed to broaden the investigationperspectives of the oil refinery.
