At present, most of the existing studies on the low-carbon operation of integrated energy systems focus on the source side and rarely extend to the load side, and do not consider the demand response characteristics of different loads. Therefore, based on the carbon flow tracing method of the power system, this paper presents a model to adjust the load side operating state of the power system by using price incentive. Firstly, the carbon flow tracing model of the integrated energy system is established, and carbon flow indexes such as node carbon potential are obtained. At the same time, considering different load types, the carbon reduction response mechanism of two loads is established through carbon trading. On this basis, according to the carbon flow index, the two-stage optimal scheduling model of the power network with the coordination and interaction between the two sides of the source and load is established and solved. The simulation results show that the model combines carbon trading and demand response, which can effectively reduce carbon emissions and significantly improve the environmental benefits of the system.</p>","PeriodicalId":72922,"journal":{"name":"Engineering reports : open access","volume":"7 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eng2.70097","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Macroscopic methods like X-ray and CT scans offer limited resolution and pose risks due to ionizing radiation exposure. In contrast, microscopic techniques such as histopathology require invasive biopsy samples and lack real-time diagnostic capabilities. Bridging this gap, THz research offers a promising solution, utilizing nonionizing terahertz radiation to achieve superior resolution. To this end, a proposed microstrip antenna emerges as a cost-effective and high-resolution tool for enabling the accurate diagnosis and detection of superficial cancers. This novel approach could revolutionize medical involvement, leading to earlier cancer detection and improved patient outcomes. The THz antenna of size 526 μm × 536 μm designed using Computer Simulation Technology (CST) software radiates at 0.3 THz with a gain of 5 dB. The antenna, when placed in the model replicating human tissue (Phantom model) radiates at 0.88 THz with a return loss of −27 dB and a gain 10 dB.

The research investigates how optimizing thixotropic slurry improves friction reduction during the jacking process. Initial results show that slurry injection reduces friction by about 33%, but as the jacking length increases, the effect strengthens, reaching over 52%. Further optimization of the thixotropic slurry enhanced its lubrication performance, achieving a maximum friction reduction of 62.3%. This optimization not only improved lubrication but also reduced the burden on hydraulic equipment, preventing excessive energy consumption and wear. By enhancing the slurry's thixotropy, a more stable lubrication film was formed between the pipeline and surrounding soil, significantly lowering friction.

Water ethylene glycol was employed as the Casson base fluid. The dimensional PDEs were transformed into dimensionless PDEs by fitting non-dimensional parameters and solved using an effectual Galerkin finite element method (GFEM). The impact of physical parameters on momentum, energy, and concentration profiles is analyzed via graphical representations. The wall friction, thermal, and solutal transport rates are tabularly detailed. It was detected that increasing the absorbency parameter, Eckert number, thermal radiation, and thermal generation improves fluid velocity. Conversely, intensifying the magnetic field, Prandtl number and inclination angle reduces fluid velocity. The nanofluid temperature declines with a mounted Prandtl number and nanoparticle volume fraction, and the opposite effect is perceived with increased Eckert, Dufour, and Soret numbers.

Poor crimping connections can lead to serious accidents, including wire breakage and dislodgement. Crimping pitch is a key factor for crimping quality, which is used to determine over-crimping or under-crimping. Currently, the indentation pitch is manually checked after operation, while the automatic method has not yet been widely studied. This paper proposes an automated crimp pitch measurement system for overhead transmission lines based on image processing with a composite algorithmic approach. First, the indentation enhancement algorithm and indentation segmentation algorithm are used on the captured image to accurately identify the indentation region. Subsequently, the Random Sample Consensus (RANSAC) algorithm utilizes identified edge points to perform robust indentation curve fitting. Finally, the actual crimp pitch is obtained according to the crimp pitch calculation formula. The test results show that the method's measurement accuracy of spacing reaches 3 mm, the maximum relative error is 3.64%, and the standard deviation of repeated measurements is 1.184 mm. The method proposed in this paper can be used for the measurement of crimp pitch, which is characterized by accuracy and efficiency.

While synthetic fibers are effective, their environmental impact often undermines sustainability goals. This study explores the potential of <i>Borassus flabellifer</i> fruit husk, typically discarded as agricultural waste in Bangladesh, as a bio-fiber alternative for thermal insulation applications. The research investigates the morphological, chemical, and thermal properties of the husk after alkali treatment with sodium hydroxide (NaOH) for varying durations. The results show that alkali treatment significantly enhances the thermal properties of Borassus husk. Notably, char content increased by up to 32%, surpassing other biofibers such as hemp, sisal, jute, and kenaf. The integral process decomposition temperature (IPDT) was found to be up to 30% higher than the untreated husk fiber, indicating improved thermal stability. Additionally, specific heat capacity (Cp) decreased by approximately 37%, correlating with an increase in integral process decomposition heat (IPDH). Scanning electron microscopy (SEM) analysis revealed that treated husks had a rougher and cleaner surface, which may improve thermal insulation properties by creating more voids and enhancing adhesion in composite materials. Fourier Transform Infrared Spectroscopy (FTIR) analysis showed reduced and shifted hemicellulose peaks, consistent with lower moisture absorption, as confirmed by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Optimal results were observed in samples treated for 0.25 and 0.75 h, suggesting that alkali-treated Borassus husk could serve as an alternative eco-friendly material for energy-efficient and sustainable engineering applications.</p>","PeriodicalId":72922,"journal":{"name":"Engineering reports : open access","volume":"7 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eng2.70103","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
