Health services, clinical studies, public health studies, health insurance data, health research, and similar sources generate a large amount of EHR. One of today’s important issues is the storage of data in centralized database systems and the fact that data accuracy and security are only ensured through these centers. Due to communication and integration issues between these centers, vital data such as examinations and laboratory tests can be repeated due to difficulty accessing the EHR. As citizens do not have full control over sharing their own EHR, this situation can cause deficiencies and disruptions in the healthcare process. Sharing personal EHR without the citizen’s consent can lead to data privacy issues. In systems where patient data is centrally stored, software changes can cause problems such as loss of patient data. The fact that the patient’s potentially valuable EHR is secondary causes irregular maintenance of the data. With its decentralized architecture and verification mechanisms, blockchain technology can work more efficiently than centralized structures without data loss or security problems. In this study, it is proposed to share EHR using blockchain infrastructure and to prepare a consensus algorithm specifically for health data on the blockchain. This way, personal EHR is stored in the patient’s own control and their own health wallet.</div></div>","PeriodicalId":48609,"journal":{"name":"Engineering Science and Technology-An International Journal-Jestech","volume":"64 ","pages":"Article 102014"},"PeriodicalIF":5.1,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143548466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Micro-mobility solutions have gained significant attention as a sustainable alternative, yet their integration into urban transport networks remains a complex task. To this end, this study introduces a geo-analytic decision-making framework for optimizing micro-mobility route planning. The methodology consists of five key steps: (i) identification and spatial analysis of 33 critical factors influencing micro-mobility adoption in a Geographic Information Systems (GIS) environment; (ii) a suitability map for the routes was generated using the state-of-the-art Fuzzy Logarithm Methodology of Additive Weights (FLMAW) and Fuzzy Simple Weight Calculation (fuzzy SIWEC) weighting methods. It was determined that criteria such as cyclist lanes, public transportation routes, terrain inclination, and recreational areas have a high impact on micro mobility use; (iii) based on this analysis, 21 optimized routes were developed, and their relationships with the main criteria were validated through Spearman’s rank correlation analysis, revealing a significant and strong positive correlation; (iv) additionally, Random Forest classification was applied to categorize routes into nine different usage classes. Route classes with different nicknames such as GreenLink and UrbanHealth Path have been created; and (v) DOmbi Bonferroni (DOBI) performance evaluation method was used to determine the preferred priority order for route construction in the study area. The results indicate that the construction priority of routes R9 and R10 is higher than that of other routes. The proposed framework offers a scalable, adaptable, data-driven, and evidence-based approach, providing valuable insights for urban planners and policymakers aiming to integrate micro-mobility into sustainable transportation strategies.</div></div>","PeriodicalId":48609,"journal":{"name":"Engineering Science and Technology-An International Journal-Jestech","volume":"64 ","pages":"Article 102027"},"PeriodicalIF":5.1,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143534412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although well-known, conventional and publicly available datasets have been proposed for the image captioning task, the lack of ground-truth caption data still remains a major challenge in the generation of accurate image captions. To address this issue, in this paper we introduced a novel image captioning benchmark dataset called Tiny TR-CAP, which consists of 1076 original images and 5380 handwritten captions (5 captions for each image with high diversity). The captions, which were translated into English using two web-based language translation APIs and a novel multilingual deep machine translation model, were tested against 11 state-of-the-art and prominent deep learning-based models, including CLIPCap, BLIP, BLIP2, FUSECAP, OFA, PromptCap, Kosmos2, MiniGPT4, LlaVA, BakLlaVA, and GIT. In the experimental studies, the accuracy statistics of the captions generated by the related models were reported in terms of the BLEU, METEOR, ROUGE-L, CIDEr, SPICE, and WMD captioning metrics, and their performance was evaluated comparatively. In the performance analysis, quite promising captioning performances were observed, and the best success rates were achieved with the OFA model with scores of 0.7097 BLEU-1, 0.5389 BLEU-2, 0.3940 BLEU-3, 0.2875 BLEU-4, 0.1797 METEOR, 0.4627 ROUGE-L, 0.2938 CIDEr, 0.0626 SPICE, and 0.4605 WMD.

Unlike existing studies, this framework incorporates detailed modeling of EV aggregation, accounting for diverse user travel patterns, time-varying energy storage capacities, and the complexities of charging and discharging behaviors. A significant innovation involves demonstrating that prohibitive constraints on simultaneous charging and discharging can, under specific conditions, be relaxed without compromising system stability, thereby simplifying the optimization process. The optimization problem is formulated as a single objective problem and solved using an improved spider monkey optimization algorithm. This algorithm delivers robust convergence, computational efficiency, and highly accurate solutions to complex energy dispatch problems.

It meticulously scrutinizes these systems within a structured framework, incorporating phase change materials and strategically positioned cylinders, leveraging advanced numerical methodologies for detailed analyses. This comprehensive investigation systematically amalgamates multiple nanomaterials and crucial parameters, offering invaluable insights into the optimization of PV/T performance within complex fluid dynamics and configurations. Examining the electrical and thermal efficiencies of the PV/T system using ternary hybrid nanofluids with nanomaterials suspended in variously shaped base fluids, this research involves a three-dimensional domain housing a rectangular block with a square base. This block integrates a phase change material (PCM), and its interior features four equally spaced circular cylinders regulating the flow of ternary hybrid nanofluids. Atop this block sits a PV panel comprised of glass, a silicon layer, and a copper absorber. The study incorporates three nanomaterials—multi-walled carbon nanotubes (MWCNT), alumina, and copper—suspended in water, each with unique shapes. These four cylinders are strategically positioned along the block’s length at 20 %, 40 %, 60%, and 80%, assuming the block’s height constitutes 20 % of its length. Utilizing the finite element method with the incompressible Navier-Stokes equations and heat equation in three dimensions, the investigation employs the conjugate heat transfer interface within COMSOL Multiphysics 6.0. It encompasses a broad array of numerical, statistical, and regression analyses to delve into the electrical, thermal, and phase transition characteristics of paraffin wax. The study scrutinizes four fundamental parameters: Reynolds number (ranging from 100 to 1000), total volume fraction of nanomaterials (ranging from 1 % to 10 %), shape factors (ranging from 3 to 5.7), and an aspect ratio (with the cylinder’s diameter-to-length ratio between 0.3 and 0.5). The present study reports an average electrical efficiency of 8.14 % for the PV/T system while achieving a maximum thermal efficiency of 71.62 %. Regression analyses indicate enhancements of 0.000008675, 0.00775855, and 0.00014403 in electrical efficiency per unit increase in Reynolds number, total volume fraction, and aspect ratio, respectively.
