Verification and Establishment of Techniques of Ajami Artwork

Ajami, a technique of painted wood paneling, was popular in the Ottoman Empire from the 17th to the late 18th centuries. Ajami art became prominent in Syria after the decline of tile production, and it rose to a sophisticated level of art in both local and global markets. Today, however, Ajami art has become almost forgotten and unknown by the modern generation, due to being an exclusive art that can be seen only in palaces, museums, and historical houses. This study investigates the traditional method and techniques of making Ajami, with a focus on the work of a renowned Syrian Ajami art master artisan named Mr. Abdulraouf. The study aims to identify and document the traditional method of Ajami production and determine the materials and techniques used for making Ajami. The study found that Ajami art consists of natural elements that are utilized in four main stages; foundation, design, painting, and finishing. The artisans have a strong preference for floral and geometric designs, influenced by Islamic religious beliefs. The findings of this study could serve as an educational guide to preserve heritage and make it presentable for the present and future generations.

Detecting Road Intersections from Crowdsourced Trajectory Data Based on Improved YOLOv5 Model

In recent years, the rapid development of autonomous driving and intelligent driver assistance has brought about urgent demands on high-precision road maps. However, traditional road map production methods mainly rely on professional survey technologies, such as remote sensing and mobile mapping, which suffer from high costs, object occlusions, and long updating cycles. In the era of ubiquitous mapping, crowdsourced trajectory data offer a new and low-cost data resource for the production and updating of high-precision road maps. Meanwhile, as key nodes in the transportation network, maintaining the currency and integrity of road intersection data is the primary task in enhancing map updates. In this paper, we propose a novel approach for detecting road intersections based on crowdsourced trajectory data by introducing an attention mechanism and modifying the loss function in the YOLOv5 model. The proposed method encompasses two key steps of training data preparation and improved YOLOv5s model construction. Multi-scale training processing is first adopted to prepare a rich and diverse sample dataset, including various kinds and different sizes of road intersections. Particularly to enhance the model’s detection performance, we inserted convolutional attention mechanism modules into the original YOLOv5 and integrated other alternative confidence loss functions and localization loss functions. The experimental results demonstrate that the improved YOLOv5 model achieves detection accuracy, precision, and recall rates as high as 97.46%, 99.57%, and 97.87%, respectively, outperforming other object detection models.

Collaborative Operation Optimization Scheduling Strategy of Electric Vehicle and Steel Plant Considering V2G

With the shortage of fossil fuels and the increasingly serious problem of environmental pollution, low-carbon industrial production technology has become an effective way to reduce industrial carbon emissions. Electrified steel plants based on electronic arc furnaces (EAF) can reduce most carbon emissions compared with traditional steel production methods, but the production steps have fixed electricity consumption behavior, and impact loads are easily generated in the production process, which has an impact on the stability of the power system. EV has the characteristics of a mobile energy storage unit. When a large number of EVs are connected to the power grid, they can be regarded as distributed energy storage units with scheduling flexibility. Through the orderly scheduling of EVs, the spatial–temporal transfer of EV charging and discharging load can be realized. Therefore, the EV situated in the steel plant’s distribution network node has the capacity to be utilized by providing peak shaving and valley filling services for the steel production load. This study proposes an operation optimization scheduling method for EVs and steel plants. Taking the lowest overall operating cost as the objective, an optimal scheduling model considering EVs operation, steel plant, and distributed generator is established. Based on the IEEE-33 node distribution network model considering distributed generators, the proposed model is simulated and analyzed, and the effectiveness of the EV steel plant operation optimization scheduling strategy is investigated.

Abstract With the modernization of agricultural production and the acceleration of urbanization, agricultural landscape planning and ecological balance control have become important issues in promoting sustainable development. Traditional agricultural production methods have problems such as resource waste, environmental pollution, and ecological damage. This article aimed to achieve scientific planning and management of agricultural landscapes, and promote the efficiency of agricultural production, rational utilization of resources, and protection of the ecological environment, thereby promoting sustainable agricultural development. This study first focused on denoising and feature extraction of agricultural remote sensing data images, using remote sensing technology to obtain agricultural landscape information. After that, artificial intelligence was adopted to achieve intelligent agricultural landscape planning, with the goal of maintaining ecological balance and promoting efficient, eco-friendly, and sustainable agricultural production. This study took the landscape of a certain city as an example to test the processing effect of remote sensing images, and it was proved that the effect was good. We tested the performance of an intelligent agricultural landscape planning and ecological balance control system based on remote sensing images. According to the experimental results, it can be concluded that the resource utilization efficiency of farmland A monitored by the intelligent agricultural landscape planning system using remote sensing image technology was 82%, while the traditional one was only 60%. This indicated that the collection effect of remote sensing image technology was much better than that of traditional technology. This article comprehensively and timely monitored and evaluated farmland through remote sensing image technology, including crop growth status, soil moisture, nutritional status, etc. The system can provide precise planting and management suggestions for farmers based on this information, and help them optimize farmland layout, crop selection, and irrigation management, thereby improving the production efficiency of farmland and crop yield.

The Internet Doesn't Exist in the Sky: Literacy, AI, and the Digital Middle Passage

AbstractThis article utilizes speculative and visual storytelling alongside interdisciplinary research on artificial intelligence (AI) and algorithmic oppression to engage in a thought experiment on how literacy studies might refuse the oppressionist logics currently undermining the possibilities of AI in literacy education. As technological advancements in education will only continue to increase and as society is yet to ascertain the parameters of an ethical AI system, it is paramount to analyze the past and present and contemplate potential futures, especially those that do not result in violence against Black and Brown peoples. To engage in speculation, we employ Endarkened Storywork (Toliver, 2022) to present an empirically driven, futuristic, science fiction narrative from two perspectives: (1) a US, Black girl who is forced to participate in AI‐structured secondary schooling and (2) a Black girl in Haiti who is forced to live in a country polluted by technological byproduct. This narrative, which is grounded in academic research and news editorials, is accompanied by comic art and followed by a companion analysis detailing the theoretical backdrop of the story. By utilizing multiple methods of scholarly distribution, we provide multiple entry points for readers to engage with this work. We offer a means for readers to see—via story, art, and scholarship—the potential impacts of AI on Black people globally. Additionally, by situating this article in the creative and scholarly realms, we strategically deconstruct traditional forms and methods of knowledge production that have constrained academic research and rendered invisible alternative forms of data representation.

Sustainable production of multimeric and functional recombinant human adiponectin using genome-edited chickens

BackgroundAdiponectin (ADPN) plays a critical role in endocrine and cardiovascular functions, but traditional production methods, such as Escherichia coli and mammalian systems, have faced challenges in generating sufficiently active middle molecular weight (MMW) and high molecular weight (HMW) forms of recombinant human ADPN (hADPN). In our previous study, we proposed genome-edited chickens as an efficient platform for producing multimeric hADPN. However, the consistency of multimeric hADPN expression in this system across generations had not been further investigated.ResultsIn this study, subsequent generations of ovalbumin (OVA) ADPN knock-in chickens showed stable multimeric hADPN production, yielding ~ 26% HMW ADPN (0.59 mg/mL) per hen. Comparative analysis revealed that egg white (EW)-derived hADPN predominantly consisted of hexameric and HMW forms, similar to serum-derived hADPN. In contrast, hADPN obtained from human embryonic kidney (HEK) 293 and High-Five (Hi-5) cells also exhibited the presence of trimers, indicating variability across different production systems. Furthermore, transcriptional expression analysis of ADPN multimerization-associated endoplasmic reticulum chaperone genes (Ero1-Lα, DsbA-L, ERP44, and PDI) indicated upregulation in the oviduct magnum of ADPN KI hens, suggesting the chicken oviduct magnum as the optimal site for HMW ADPN production. Lastly, the functional analysis demonstrated that EW-derived hADPN significantly reduced lipid droplets and downregulated lipid accumulation-related genes (LOX-1, AT1R, FAS, and FABP4) in human umbilical vein endothelial cells (HUVECs).ConclusionIn summary, stable and functional multimeric hADPN can be produced in genome-edited chickens even after generations. This highlights the potential of using chicken bioreactor for producing various high-value proteins.

Comparison of different hydrogen-ammonia energy conversion pathways for renewable energy supply

Hydrogen and ammonia are considered promising energy carriers for renewable energy due to their environmental friendliness and medium- and long-term storage cost advantages. However, a single hydrogen or ammonia energy strategy generally cannot meet the demand, limiting widespread application. Here we consider the whole process of renewable energy generation-transmission-storage-consumption, and propose a hydrogen-ammonia combined operation strategy. Assuming a rated power of 40 MW for generation and 10 MW for demand, we compare five energy conversion pathways: hydrogen or ammonia pipeline transmission, high-voltage alternating current (HVAC) transmission with hydrogen or ammonia storage, and HVAC transmission with hydrogen-ammonia hybrid energy storage. Results indicate that for a transmission distance of 100 km, the most economical pathway is HVAC transmission with hydrogen-ammonia hybrid energy storage, with a net present value (NPV) of 39.31 M$ and a levelized cost of electricity (LCOE) of 0.081 $/kWh. Sensitivity analyses reveal that a 0.01 $/kWh increase in electricity price leads to NPV growths of 11.75–16.02 M$. This pathway achieves zero carbon footprint and saves 4.7 M$ annually in carbon taxes. Compared to traditional production methods, this pathway is equivalent to reducing emissions by 94,189 tons.

АНАЛІЗ ПРИЧИН ВИНИКНЕННЯ ТА СПОСОБІВ ЗМЕНШЕННЯ ЗАЛИШКОВИХ НАПРУЖЕНЬ ПРИ SLM

Additive manufacturing (hereinafter – en. AM) is a modern set of technologies that make it possible to quickly and qualitatively create products with a unique geometry that are impossible or difficult to produce by traditional production methods. Currently, researchers pay attention to two major areas, namely AM quality systems and the search for new regularities in already well-known materials that were produced in a traditional way. This technology has a number of advantages for the manufacture of aerospace products, but, like all production technologies, this technology has a number of disadvantages and problems. Residual internal stresses are one of the features of metal materials produced by layer-by-layer fusion using SLM technology, but they can significantly affect mechanical properties and geometric parameters. Their presence is especially important for AM materials, which inevitably lead to significant internal stresses. Thus, the issue of reducing the influence of internal stresses requires a fundamental understanding of their influence on the geometric parameters and service characteristics of AM materials.

THE POTENTIALS OF ULTRASONIC ATOMIZER AUGMENTED THE SEA SALT PRODUCTIONS

Ultrasonic atomizers can potentially augment the production of sea salt through a process known as ultrasonic nebulization. While the traditional method of sea salt production primarily relies on natural evaporation, ultrasonic atomization can accelerate the evaporation process. The process typically involves the following steps: collection of seawater, evaporation, brine crystallization and then harvesting process of the sea salt. After processing, the sea salt is typically dried and packaged for distribution and sale. In this project, influencing of ultrasonic atomizer in the process a saline water into the brine, before crystallization can be proceeded. The ultrasonic atomization process significantly increases the surface area of the seawater by converting it into fine droplets. Droplets evaporate more efficient due to large surface area of the droplets. According to testing of the research apparatus which had been conducted, an ultrasonic atomization can increase the salinity by brine evaporation or of droplet productivity of sea salt. This result had been shown that this process can be used to increasing the salinity of sea water. For further steps, this technique can potentially augment the production of sea salt.
