The design of composite I‐sections in aerostructures faces a significant challenge with conventional laminates because they are prone to delamination under out‐of‐plane loads. To address this issue, this study investigates the design, manufacture, and mechanical properties of 3D woven near‐net‐shaped composite I‐sections. The study also compares their advantages with equivalent laminates and examines the influence of weave patterns on their mechanical behavior. Specimens were manufactured using the vacuum‐assisted resin transfer molding technique, and quasi‐static tensile, compressive, and bending tests were conducted to assess the properties of I‐sections with three different weave patterns. It finds that the ultimate strength and damage tolerance of the considered design of 3D woven I‐sections are better than the considered design of 2D woven laminated counterparts, and different weave patterns play a significant effect in damage mode and load‐bearing capacity. In addition, using 3D woven preforms to manufacture composite I‐sections also exhibits shortened production time in terms of layup and resin infusion. Highlights: The 3D woven I‐sections show improved damage tolerance over 2D counterparts.The design of weave patterns affects the properties of I‐section composites.Using 3D preforms to manufacture I‐sections exhibits shortened production time.Design consideration is proposed for the optimal weave pattern of the I‐sections.

Mariette Monpierre's and Michel Reinette's 2022 documentary, Les Derniers Blancs Matignon de Guadeloupe, and Estelle-Sarah Bulle's 2018 novel, Là, où les chiens aboient par la queue emblematize the complexities involved in reimagining postcolonial identities in Guadeloupe, especially that of the Blancs-Matignon. They are a mostly White, endogamous, and isolated group who have had a discreet existence in the thickly forested inland region of Grands-Fonds du Moule since the late 1600s. Through an analysis of the documentary and parts of the novel, the article explores historical, cultural, and linguistic convergences between the Blancs-Matignon and the majority Black and mixed-race population of Guadeloupe. The identity politics of weaving the narratives of the Blancs-Matignon into the matrix of Guadeloupe's contemporary society will also be examined. [ABSTRACT FROM AUTHOR]

Vehicle lane‐changing behaviour is often regarded as transient traffic behaviour while ignoring behavioural characteristics of the lane‐changing process. A combined prediction model based on wavelet transform (WT) and dual‐channel neural network (DCNN) is proposed to explore the selection behaviour of lane‐changing distance by taking lane‐changing behaviour in an urban inter‐tunnel weaving section. Firstly, the extracted lane‐changing data are analysed for correlation and noise reduction, and the main factors affecting lane‐changing distance are taken as input variables of the model. The trajectory data of the inter‐tunnel weaving section of the "Jiuhuashan‐Xi'anmen" tunnel in Nanjing, China, are used to improve the prediction of vehicle lane‐changing distance by training the model. The results show that the proposed WT‐DCNN model has high prediction performance when compared with existing artificial neural network (ANN), DCNN and wavelet neural network (WNN) models. The characterization and study of the typical lane‐changing behaviour in the weaving section can lay the theoretical foundation for the development of an urban inter‐tunnel weaving section management scheme.

The excellent load-bearing performance of sized warp yarns can reduce the end-breakage rate and enable them to complete weaving smoothly. Evaluating the load-bearing performance of sized warp yarn can guide the sizing process and weaving production. For this purpose, the study evaluated the load-bearing performance of cotton sized warp yarn. First, based on the JN-01 tester, a weaving load simulation tester of sized warp yarn, the test sample capacity for the load-bearing life was determined to be 50 ends using a U-test. Second, by testing three cotton sized warp yarns with different linear densities, the universality of the parameter conditions of the tester was verified. Third, with the JN-01 tester, the breaking strength and hairiness under different load-bearing cycles were measured, and it was found that the breaking strength of the sized yarn was linearly related to the load-bearing cycles. In contrast, the hairiness of the sized yarn was logarithmically related to the load-bearing cycles. According to regression analyses, evaluation indicators were extracted to characterize the strength loss resistance and anti-fuzzing performance of sized warp yarns, which were the residual enhancement rate and hairiness after friction. The evaluation results of sized warp yarns, with different linear densities and different sizing ratios, showed the effectiveness of the evaluation indicators. Finally, by verifying the effectiveness of samples from three factories, based on the evaluation indicators in this paper, the results revealed that the constructed evaluation method effectively evaluated the load-bearing performance of cotton sized warp yarn.

- Abstract
In this study, six groups of woven spacer fabrics with different structural parameters such as the spacer yarn pattern (V and W pattern) and spacer yarn density (denting pattern) were produced, and their compressional behaviour was investigated. According to the experimental results, the V-pattern spacer fabrics revealed better compressional resistance compared to the W-pattern spacer fabrics. Besides, it was observed that the spacer fabrics produced with lower spacer yarn density, were more susceptible to compressional forces. Statistical analysis of results demonstrated that all compressional parameters, except relative compressibility and thickness recovery, were affected by the spacer yarn pattern and density. Finally, the compressional behaviour of woven spacer fabric was correlated by three viscoelastic models (Kelvin model, Maxwell model, and three-component model with a nonlinear spring) and also the Van Wyk Theory. The results of curve fitting exhibited that the three-component model with nonlinear spring well fitted the experimental data. [ABSTRACT FROM AUTHOR]

Crepe weave fabrics, known for their pebbly or crinkled (rough) surface, are widely used in clothing and bedding applications. Crinkled appearance for crepe weave can be achieved by different interlacement patterns. Generally, six methods/interlacement patterns are commercially used for fabricating crepe woven fabrics. However, there isn't any significant study reporting clothing comfort and mechanical attributes of crepe variants. In this study, crepe fabrics were developed by these six methods i.e., Base sateen (BS), Reversing method (R), Superimpose (SI), Subset (SS), Quarter turn (QT), and Plain base (P) methods. The yarn linear density, fabric density, and other fabric parameters were kept the same to determine the best development method for fabricating crepe woven fabric having higher thermal, sensorial, and mechanical properties. Characterization data revealed that each crepe variation possesses unique structural and physical parameters making performance differences i.e., the BS specimen exhibited the highest air permeability owing to higher porosity, the R specimen had superior Overall moisture management capability (OMMC) index due to compact yarn linkage, and the SS specimen showed best thermal conductivity performance due to its sophisticated crinkled appearance. Among mechanical attributes QT exhibited higher tensile and puncture strengths due to its compact structure with higher interlacements however, sateen interlacement governing yarn slippage made the tear strength higher for the BS specimen.

Developing advanced engineering polymers that combine high strength and toughness represents not only a necessary path to excellence but also a major technical challenge. Here for the first time a rigid‐flexible interlocking polymer (RFIP) is reported featuring remarkable mechanical properties, consisting of flexible polyurethane (PU) and rigid polyimide (PI) chains cleverly woven together around the copper(I) ions center. By rationally weaving PI, PU chains, and copper(I) ions, RFIP exhibits ultra‐high strength (twice that of unwoven polymers, 91.4 ± 3.3 MPa), toughness (448.0 ± 14.2 MJ m−3), fatigue resistance (recoverable after 10 000 cyclic stretches), and shape memory properties. Simulation results and characterization analysis together support the correlation between microstructure and macroscopic features, confirming the greater cohesive energy of the interwoven network and providing insights into strengthening toughening mechanisms. The essence of weaving on the atomic and molecular levels is fused to obtain brilliant and valuable mechanical properties, opening new perspectives in designing robust and stable polymers.

This article draws on a 2017 paper in TEXTILE which reports on a project on live coding and ancient weaving, entitled Weaving Codes/Coding Weaves (WC/CW). The 2017 paper introduces the concept of Kairos, which has widespread cultural and social applications. Kairos as articulated in WC/CW can illuminate practitioner knowledge and understanding in any creative practice. The article first discusses the research project and draws implications for other practices. The next section moves into the relevance of WC/CW to education, in its fundamental cultural role, and to teaching in particular. This leads to a discussion of the nature of practice. The last section draws out themes and implications, particularly on how Kairos might yield insights into the discussion of practice-based knowledge and understanding made by such thinkers as Dewey, Schön and Eraut. Kairos is a concept which together with Phronesis is particularly pertinent in the analysis of the epistemology of practice. [ABSTRACT FROM AUTHOR]

Yazzie, Ramona F., Masker, Kimberly, and Biggins, Kristin
- Abstract
The Navajo Nation is one of the many reservations that lack access to health care services, leading to increasing chronic health conditions. Navajo rug weaving is a common creative occupation on the reservation. Navajo rug weaving involves multiple steps in creating a beautiful rug. The multiple steps include repetitive gripping, pinching, reaching, pulling, and prolonged sitting. Therefore, weavers are at risk for developing musculoskeletal disorders (MSDs), preventing individuals from participating in meaningful occupations. Occupational therapists have the skills to provide appropriate education through active listening, visual handouts, and family members. However, occupational therapists must demonstrate and understand cultural sensitivity to address cultural occupations. This article will provide strategies for modeling understanding of the Navajo people, Diné, and rug weaving. [ABSTRACT FROM AUTHOR]

Warp sizing significantly influences both the efficiency of weaving machines and the overall quality of the woven fabric, playing a crucial role in the weaving preparation process. Ensuring precise control of process parameters and equipment status during the sizing process is essential to maintain desirable sizing quality. This paper clarified the research significance of squeezing from the perspective of its application in warp sizing. Moreover, research advances in the squeezing device, including the structure, material, surface state of squeezing and sizing rollers, the configuration of the squeeze and sizing rollers, the spraying device, the pressurization methods for the squeezing roller, and their influence on sizing performance were reviewed in detail. A comprehensive analysis and summary were conducted to explore the correlations between sizing quality and diverse squeezing technical parameters, encompassing squeezing force, surface hardness of rubber-covered sizing and the squeezing roller, squeezing width, warp speed, and immersion time. In addition, this article also outlines the mathematical models related to the squeezing process and the characterization methods of the squeezing effect. Finally, it offers a glimpse into potential future research directions concerning the squeezing process. [ABSTRACT FROM AUTHOR]

The utilization of core‐spun yarns with spandex has achieved significant interest over the past decade because of their exceptional stretchability, resilience, and comfort features. The main objective of this study was to evaluate the effects of changing the spandex denier and twist multiplier on the physio‐mechanical properties of 16 Ne core spun yarn and the produced denim fabric using these yarns as weft. Core‐spun yarns were produced from three different spandex deniers at various TM values, where cotton roving was used as the sheath. Fabrics were manufactured using an air‐jet weaving machine with the core spun yarn as weft and 100% ring cotton yarn as warp (12 Ne) following the identical 3/1 twill weave pattern. Results reveal that using different spandex percentages shows better results at different TM parameters. Both yarn and fabric were attained at a twist multiplier of 5.0, 5.5, and 6.0 for 40, 70, and 105 D, respectively. Additionally, it was discovered that the yarn produced using lower spandex denier gives higher tenacity for yarn and fabric. However, the yarn produced using a higher spandex denier gives higher elongation percentage for yarn, higher tear strength, recovery, and lower growth percentage fabric. Highlights: Influence of spandex denier and twist multiplier on the physio‐mechanical properties of core‐spun yarn and the resulting denim fabric.The higher spandex denier exhibited greater tear strength, better recovery, and lower fabric growth percentages.Increasing the twist multiplier initially increased the tenacity and elongation percentage of yarns and fabrics, followed by a decrease.Higher spandex percentages reduced hairiness and increased with higher twist levels.Higher spandex denier indicates the need for tailored TM settings based on spandex denier to achieve desired fabric properties.

In order to optimize the design of three-dimensional tubular woven (3DTW), a design method and matrix model of 3DTW were proposed based on normal loom, where 3D woven was used as tube wall and the weaving method of tubular fabric was applied. Herein, 3D woven was used as the tube wall to obtain the face weave diagram, and the back weave diagram was subsequently obtained by the "negative flip" method. According to the method of layering weaving, the structure diagram of 3DTW could be determined. In order to obtain back weave matrix, the elements in the face weave matrix were replaced and reordered by MATLAB function, and Kronecker product operation was used to achieve the proportional embedding of the face and the back weave matrix and the assignment of the face warp by lifting point elements when weaving the back weft. Finally, the weave matrix of 3DTW was obtained. The proposed design method and matrix model can improve the design efficiency and reduce weaving cost of 3DTW, which could provide a reference for the design and preparation of 3DTW.

Home-making processes have been an important subject of investigation for decades. This research furthers the scholarship in this area by exploring how young urban Indonesians develop psychological homes to create habitable spaces for themselves, with reference to their various relational networks, activities, objects, and pets. We draw on fieldwork conducted over a 16-week period with 45 young people in Surabaya and subsequently extended through diary analysis. To analyze and interpret the empirical materials generated, we drew insights from assemblage theory which revealed that the lived experiences of youth in developing psychological homes for themselves are fluid and dynamic processes, involving both human and physical elements. Our exploration began with the key elements that participants used to develop psychological homes. We then also explored their practices in weaving together these key elements to navigate everyday tensions within their broader relational networks. This article demonstrates the utility of assemblage thinking in unpacking the everyday practices of homemaking among youth. [ABSTRACT FROM AUTHOR]

Building on Tim Ingold’s theory on human correspondence, this visual essay plays with the photos of #EverydayNile, a project involving photojournalists from different Nile basin countries to re-picture the river through stories of everyday water practices. # EverydayNile's initial query was: how can we use photos to elicit a conversation and promote shared understandings about the river across countries? The idea of correspondence invites weaving together images from different stories around knots defined by specific photographic elements: focus, composition, time, framing, and light. This visual essay shows how through corresponding we can practice imagination in communication, to create a political community engaged in a dialogic conversation on the river as a common.

During excavations carried out in 2023 at the cemetery of the Lusatian culture in Dąbrowa, site 2, Wieluń County, an urnless cremation burial was discovered (Object 24), which is dated generally to the Hallstatt period. Burnt human bones were scattered throughout the object, which form a relatively compact cluster in the central part of the grave. Ceramic fragments from various vessels were found in the fill of the grave cavity. Metal objects, both bronze and iron, showed signs of being smoldered in the fire. This fosters the conclusion that they had been burned with the deceased on the pyre and placed in the grave together with burned human bones. At the same time, such a state of preservation of the grave offerings made it impossible to specify the dating of the tomb. Within the grave, a fragment of an iron plate was found, on which mineralized remains of fabric were preserved. Technological analysis showed that it was a half-basket weave fabric of a very high quality, made of thin z-single yarn (0.25–0.30 mm and 0.40–0.50 mm) and of surprisingly high thread count (32–34/12–14 threads per cm). In the basin of the Vistula and the Oder rivers, none of the fabrics discovered so far had similar parameters. On the other hand, textiles from the main canters of weaving production at the time, such as the Hallstatt culture and the Scandinavian area, showed similar characteristics, but only in rare examples. This highlights the importance of the weaving product presented here. It is difficult to answer conclusively whether we are dealing in this case with an imported object or one produced in a local weaving workshop, although much points to the first option. Given the context of the find and the accompanying offerings, it can be assumed that the fabric belonged to a person of a higher social status. The local community’s custom of accumulating and then depositing imported items of quality into graves also makes such a hypothesis plausible. On the other hand, certain foreign patterns were adopted and creatively developed in local craft workshops of the Lusatian Culture. Most likely, involvement in long-distance trade routes allowed this society to achieve a high position in the aforementioned exchange. It was important to settle and control areas located in the basin of the upper Warta and Prosna rivers, i. e., on the southern borderlands of central Poland. It was here, through Silesia, that foreign patterns flowed in, which were then transmitted further along the Warta river basin in the northern direction, towards the “Lusatian interior”. The communication route created for the Baltic amber trade played an important role here. Finds of this raw material were recorded both in the Hallstatt circle, in areas of northern Italy, and present-day Slovenia. [ABSTRACT FROM AUTHOR]

Electronic textiles (e‐textiles) combine electronic functions (e.g., sensing, actuating, data processing) with textiles. E‐textiles are a platform technology with the potential for ubiquitous deployment in any application scenario where textiles can be found. E‐textiles have attracted significant research interests from materials and manufacturing process development to applications such as sports/fitness, healthcare, and workwear. While significant advances have been made in the research domain regarding the integration of electronic functionality, the technology is relatively immature and significant challenges remain in the manufacturing of commercialized e‐textile systems. This paper reviews the state of the art in e‐textile manufacturing including materials (e.g., yarns, inks), fabrication (e.g., weaving, knitting, printing), electronic integration and interconnections. This paper also reviews the key principles of textile sustainability and electronic waste (e‐wastemanagement, which provide useful guidance on e‐textile design and manufacturing to minimize their impact on the environment. Examples are given to demonstrate the early work toward sustainable e‐textiles. The remaining research challenges regarding scalable and sustainable manufacturing of e‐textiles are presented.

Development is an important, yet contentious word, in the history of post‐colonial Sri Lanka. Typically, it is linked with economic progress and societal change, intricately woven into political processes and frequently utilized as a platform to promote Sinhala‐Buddhist ethnonationalist agendas. This article looks at post‐colonial Sri Lanka's 'core development project' — the Mahaweli Development Programme — and its post‐war revival with the military as a key actor. Through a detailed ethnographic study, it traces the way in which the military assumed extraordinary powers and became vital to the post‐colonial project of development and the militarized practices that enabled this. The author argues that this project of militarized development unfolds in a fourfold manner: by normalizing the presence of the military; by ensuring the military is seen as charitable; by blurring the boundaries between the military and civilians; and lastly by portraying the work carried out by the military as transformative. The article concludes by demonstrating that this militarized project of development is the latest iteration of the long‐standing post‐colonial project of Sinhala‐Buddhist state expansion, enabled through development.

This article proposes an intercultural analysis of gesture and timbre in Fujikura Dai's neo for solo shamisen (2014). I analyze neo through the concept of te, a term used by shamisen players to refer to 1) recurring melodic patterns; and 2) their characteristic fingerings, hand positions, and performance techniques. My analysis of neo highlights how a performer's use of te can shape the form of a piece. Through aural and visual analysis of performances by shamisen player Honjoh Hidejirō, I demonstrate how the form of neo unfolds through changes in te. Weaving together the embodied knowledge of shamisen players, Japanese and U.S./Canadian theories of fretboard topography, and performance analysis, my consideration of te serves as an intercultural mode of analysis that reflects Fujikura's and Honjoh's backgrounds in Western art music, shamisen performance, and rock.

Māori conceptualisations of ancestral environs and its connections to memory often reside in the realm of whakapapa (genealogy) having originated from Papatūānuku and Ranginui (primordial ancestors and gods), their loving embrace, and their eventual separation that carved the space for nourishing lands and waters. These stories of whakapapa were passed down intergenerationally through many Māori creative expressions, including waiata (songs), haka (posture dance), pūrākau (stories), whakataukī (proverbial sayings), ruruku (sequence of incantations), and karakia (prayers). This has resulted in a genealogically and environmentally derived Māori music theory. The disruption of settler-colonialism aimed to sever whakapapa from the memory as being reflected in our ancestral environs and within the hearts of Māori. 'He Whiringa Wainuku' refers to the weaving of water elements on earth and sets the imagery for decolonising the interconnections of whakapapa, land, water, and memory through Kaupapa Māori methodologies and Māori creative expressions.

Certain aspects of the temporal dimension in analysis are taken up in light of Steinbock's illuminating exploration of a Winnicott case report. Following Steinbock's portrayal of the interrelation of linear and non-linear time dimensions, some consideration is given to the many different kinds of time encountered in analysis, and to the function of the frame in creating a specifically analytic experience of time duration. The concept of Transitional time is proposed to describe this peculiarly analytic state of consciousness in which heterodox qualities of psychical experience can be woven together, and the multi-dimensionality of time itself is integrated into the experience of going-on-being.

Arc weaving is a feasible technique for making thick-walled components in the arc-based directed energy deposition process (DED-Arc). In the current study, four different arc weaving strategies, namely, triangle, square, semi-circle, and helix, are used to fabricate the walls. For this, gas tungsten arc welding (GTAW) based DED-Arc set-up using aluminium alloy wire (ER4043) as a filler material is used for different printing strategies. The fabricated walls were investigated for their surface characteristics, microstructure, mechanical properties and residual stress. The weld-bead and wall geometry study revealed that for the same number of layers, the semi-circular arc-weaving strategy had the maximum height among all, with an effective area of 65.77 %. The waviness of the side surface of the walls was maximum for the semi-circle (714 ± 35 µm), indicating the semi-circle will require almost twice the amount of machining than the helix, square, and triangle in postprocessing operation. The optical micrographs showed that the semi-circular weaving pattern exhibited a coarser gain with thicker grain boundaries with an average grain size of 46.4 ± 23.7 µm as compared to other weaving patterns. The triangle weaving pattern demonstrated the smallest grain size among all, resulting in high hardness and superior wear resistance. The residual stress (RS) results revealed that the RS is in tension (22–24 MPa) in the bottom layers for all the walls and becomes almost zero (−1.5 to −2.5 MPa) in the top layers except for the walls formed by helix strategy. The square weaving strategy strikes a balance between surface characteristics, microstructure, and mechanical properties, making it a highly viable option for thick wall fabrication.

OPERATOR theory ,HILBERT space ,WEAVING ,WEAVING patterns - Abstract
K-frames are more generalized than ordinary frames, particularly in terms of their weaving properties. The study of weaving K-frames in Hilbert space has already been explored. Given the significance of n-Hilbert spaces in functional analysis, it is essential to study weaving K-frames in n-Hilbert spaces. In this paper, we introduced the notion of weaving K-frames in n-Hilbert spaces and obtained some new properties for these frames using operator theory methods. First, the concept of weaving K-frames in n-Hilbert spaces is developed, and examples are given. By virtue of auxiliary operators, such as the preframe operator, analysis operator, and frame operator, some new properties and characterizations of these frames are presented, and several new methods for their construction are given. Stability and perturbation results are discussed and new inequalities are established as applications [ABSTRACT FROM AUTHOR]

This research examines the utility of combined crash modification factors (CMFs) in minimizing crash severity at urban roundabouts. Conventional CMFs typically assess the influence of singular interventions on road safety. However, traffic dynamics and the interactions among multiple safety measures necessitate a more comprehensive strategy. This study introduces a novel methodology for developing integrated CMFs that accounts for the interactive effects of multiple safety measures, providing a comprehensive understanding of their collective impact on road safety. The investigation utilized data from 16 urban roundabouts in Amman, Jordan, from 2015 to 2021. Regression models have been employed to develop individual and combined CMFs for various geometric and traffic characteristics, such as entry and exit widths, speed limits, and weaving patterns. Key findings indicate that interventions, such as reducing speed limits, modifying entry and exit widths, and adjusting weaving lengths, significantly improve safety. The analysis identifies hazardous roundabouts and proposes effective single and combined treatments to mitigate crash risks. This study highlights the importance of considering multiple treatments simultaneously to improve the predictive accuracy of safety assessments and supports the development of more effective road safety strategies tailored to specific crash types and severities. The approach demonstrates a significant potential to enhance road safety analysis and decision-making, ultimately contributing to safer road environments. [ABSTRACT FROM AUTHOR]

In this article, we propose a geometric modeling method for an integrally stiffened panel using 3D woven composites. To observe the geometric shapes of the panel, we design weave patterns in which the skin and stiffener are integrated and manufacture the panel. Cross-sections of the manufactured panel are observed using a microscope, and paths and shapes of tows are modeled using weaving parameters and the obtained cross-sections. To verify the method, buckling analysis is performed on the panel and compared with test results. The proposed method can be effectively applied to the design of integrally stiffened panel using 3D woven composites. [ABSTRACT FROM AUTHOR]

Sense-making processes shape the messages and impacts of qualitative research. Using qualitative data analysis methods embedded within a Pacific-Indigenous research paradigm decolonises research. This article discusses the Pacific-Indigenous data analysis processes of talanoa and fa'afaletui employed within a study of Pacific elder care in Aotearoa New Zealand, conducted by scholars of Pacific/Moana heritage. While research literature has primarily identified talanoa and fa'afaletui as data collection methods, we discuss our use of talanoa and fa'afaletui as methods of analysis. Talanoa and fa'afaletui were engaged as collective processes of orality weaving understanding from the researchers' lived experiences and navigating across languages. Enhancing authenticity and actionability are identified as benefits of talanoa and fa'afaletui collective data analysis. Considerations for implementing these methods are language, logistics and location. [ABSTRACT FROM AUTHOR]

Although an increasing amount of research has focussed on the relationship between student language proficiency and English‐medium instruction (EMI) programme outcomes, there has been little focus on the broader assessment of progress and learning within EMI programmes, especially in Asia. The purpose of this study was to determine the kinds of programme assessments used throughout all stages of full‐degree EMI programmes in Japan. Our inquiry examined the benchmarks currently in place to measure content knowledge, language proficiency and academic skills competence in undergraduate EMI programmes. Data were collected from 13 universities in Japan with well‐established EMI degree programmes. In this paper, our findings are explored primarily in a qualitative and holistic manner, weaving the results of our survey together with the extant literature on the topic and our lived experiences as teachers in EMI programmes in Japan. Embedded in this conversation are evidence‐based suggestions for improved practice in EMI programmes in Japan. [ABSTRACT FROM AUTHOR]

Methods for evaluating the fluctuation of texture patterns that are essentially regular have been proposed in the past, but the best method has not been determined. Here, as an attempt at this, we propose a method that applies AI technology (learning EfficientNet, which is widely used as a classification problem solving method) to determine when the fluctuation exceeds the tolerable limit and what the acceptable range is. We also apply this to clarify the tolerable limit of fluctuation in the "Kurume Kasuri" pattern, which is unique to the Chikugo region of Japan, and devise a method to evaluate the fluctuation in real time when weaving the Kasuri and keep it within the acceptable range. This study proposes a method for maintaining a unique faded pattern of woven textiles by utilizing EfficientNet for classification, fine-tuned with Optuna, and LightGBM for predicting subtle misalignments. Our experiments show that EfficientNet achieves high performance in classifying the quality of unique faded patterns in woven textiles. Additionally, LightGBM demonstrates near-perfect accuracy in predicting subtle misalignments within the acceptable range for high-quality faded patterns by controlling the weaving thread tension. Consequently, this method effectively maintains the quality of Kurume Kasuri patterns within the desired criteria. [ABSTRACT FROM AUTHOR]

With the rapid development of intelligent manufacturing, Digital Twin technology, as an advanced tool for the intelligentization of weaving workshops, has endowed weaving services with real-time simulation and dynamic optimization capabilities while also placing higher demands on the digital capabilities of workshops. The diverse and multi-manufacturer equipment in weaving workshops exacerbates the complexity of multi-source heterogeneous data. Moreover, traditional data collection methods, which are mostly based on fixed frequencies, increase the network load during real-time high-frequency data reception, making stable, long-term operation difficult. Conversely, low-frequency collection might miss important state changes, thus affecting the quality of weaving big data. To address these issues, this paper proposes a service-oriented Digital Twin modeling method for weaving workshops. This method combines OPC Unified Architecture (OPC UA) with a state change-based data collection approach, utilizing a sliding time window (STW) to identify anomalous data and employing median interpolation to correct these anomalies. The goal is to enhance the representation capability of the Digital Twin in the weaving workshop by improving the data quality. For a specific service of predicting the warp-out time of 288 air-jet looms in a workshop, the average error of the predicted warp-out time using the dynamic data set proposed in this study was reduced from 0.85 h to 0.78 h compared to the static data set based on fixed frequency, an improvement of 8.2%, thereby validating the effectiveness of the proposed method.

The integration of diverse weaving angles in vascular stent design proves beneficial for addressing complex applications such as bending, branching, and load-bearing. However, the weaving process may introduce frictional corrosion issues among threads, necessitating further investigation into frictional behaviors at different weaving angles. This study simplifies the contact between nickel-titanium (NiTi) alloy threads in woven stents as line-to-line contact between rods. A proposed in vitro experiment, based on weaving angles of 30°, 45°, 60°, 75°, and 90°, systematically analyzes friction and wear characteristics, including friction coefficients, wear parameters, and morphology. Findings indicate significant impacts of weaving angles on tribological behaviors, with 30° weaving angle stents exhibiting the lowest wear rate. The study identifies four developmental stages in the life cycle of line-to-line contact wear: breaking-in wear, steady wear, severe wear, and post-stable wear. Under 25% calf serum lubrication, lower friction coefficients and wear rates are observed, validating NiTi alloy suitability for lubricated human environments. The investigation reveals a nonlinear correlation between weaving angles, friction cycles, and wear rates, offering insights for the tribological design of woven instruments. [ABSTRACT FROM AUTHOR]

Aiming at the trend of denim yarn and the deficiencies of the current dyeing, characteristics of denim colored yarn were simulated and a multi-colored yarn by vortex spinning was developed. Traditional ring spinning and air-jet vortex core-spun technology were combined. Short staple fibers were taken as core yarn instead of filament to achieve the color of core yarn, the thickness and twist direction could be adjusted. The twisting stress of the fibers was counteracted by combining the core yarn with the opposite twist direction of the outer layer fibers and selecting the corresponding twist coefficients during the spinning process. The use of uneven wrapping effect of the air-jet vortex spinning could highlight the unique exposed core effect, inner and outer layers could be used in different colors and ratios. The multi-colored yarn by vortex spinning coud be used for knitting and weaving, the rich color variation of multi-colored yarn by vortex spinning was suitable for the production of dye-free denim production.
