Domain adaption is a robust tool for cross-domain learning to reach a consistent target. Current research aims to study the feasibility and effectiveness of domain adaption from ordinary endoscopic images to capsule endoscopic images in quality controlling. Dynamic adversarial adaptation network (DAAN) was trained to identify low-quality images using ordinary endoscopic images with corresponding labels (source domain with supervision) and capsule endoscopic images without corresponding labels (target domain without supervision) so that image quality controlling can be transferred from ordinary to capsule endoscopic images. 62,850 images from capsule endoscopy and 17,434 images from ordinary endoscopy were included in developing deep learning models. In internal cross-validation, DAAN achieved an average area under receiver operating characteristic curve (AUROC) of 0.8638 (95% confidence interval [CI] 0.6753–1.0000) in filtering low-quality images for capsule endoscopic images, compared with CNN B/16 and L/32, which were also trained with ordinary endoscopic images with corresponding labels. 18,636 images from 355 patients who received capsule endoscopy were prospectively collected. The AUROC of DAAN reached 0.9471 (95% CI 0.9428–0.9511), which surpassed CNN (0.8570 and 95% CI [0.8529–0.8608]) and ViT (L/32: 0.8183 and 95% CI [0.8143–0.8220] and B/16: 0.7779 and 95% CI [0.7960–0.8036]). Domain adaption can complete image quality controlling task in capsule endoscopic images with the supervision of ordinary endoscopic images, whose quantity is smaller so that the annotation workload can be alleviated.","PeriodicalId":72922,"journal":{"name":"Engineering reports : open access","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eng2.12776","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136314074","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}

In actual production, the efficiency of workers will change with time due to their proficiency, fatigue, and other effects. In this article, we attempt to solve the problem of multi-skilled workers allocation in unit brake production lines considering the heterogeneity of skills and time-varying effects. A nonlinear mixed-integer programming model is established, which fully considers the impact of worker efficiency due to proficiency, fatigue, and multi-task rest recovery. The product production cycle and worker cost are the two objectives of the optimization solution. An enhanced NSGA-II algorithm that combines the improved NSGA-II algorithm and the variable neighborhood search (VNS) algorithm is used to solve the multiobjective optimization problem. Finally, the weighted ideal point method is used to obtain the Pareto optimal solution. The application case of a unit brake production is considered to evaluate the proposed model. The results indicate that the time cost and salary cost of workers are reduced by 8.03% and 18.91% compared with the original scheduling. The scheduling model considering learning, fatigue and recovery factors is more suitable for the actual production situation, ensuring the completion time and reducing the labor cost.","PeriodicalId":72922,"journal":{"name":"Engineering reports : open access","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eng2.12774","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135015431","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}

Load balancing is one of the biggest problems, especially when User Equipment (UE) uses received signal strength to connect to different transmission power network tiers. Spectrum for small cells has not been used to its full potential. While all the cells are using the same frequency spectrum and the small cells overlap the Macro Cells, preventing interference is another big problem. The proposed Cell Range Extension (CRE) and Almost Blank Sub-frame (ABS) provides a solution to overcome these challenges. The proposed ABS in this paper is novel because it is a partial muting one rather than the full muting ABS in recent research studies. In addition, the cell association method is by distance rather than conventional Reference Signal Received Power (RSRP). CRE-ABS has been applied simultaneously to solve both load balancing and interference. Simulation results show that the proposed scheme achieves substantial throughput and Jain's Fairness Index (JFI).","PeriodicalId":72922,"journal":{"name":"Engineering reports : open access","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eng2.12772","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135208108","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}

Using the data for 416 chicken farmers in four districts and counties of Guangdong Province as the sample, the theoretical framework proposed in this article is tested by constructing multiple linear regression models and structural equation models. The results are as follows: Both vertical and horizontal specialization can bolster the income of farmers, but they have different specific mechanisms of action. Vertical specialization promotes agricultural income through the mediating effect of horizontal specialization. It is evident that the discussion of horizontal specialization of farmers should not be separated from the conditions of vertical specialization. The policy effect of emphasizing horizontal specialization alone may be limited. Especially for those farmers who are limited by their own endowments and objective conditions to increase their horizontal specialization level and production scale in the short term, it is more important to promote their vertical specialization level.","PeriodicalId":72922,"journal":{"name":"Engineering reports : open access","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eng2.12761","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135690086","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}

An ex-post factor research approach was adopted, and Pearson's correlation and Regression Analysis were fitted with the data using Minitab software. The results of the study highlighted that first-year GPA had a strong positive relationship with final-year CGPA which is an indication that first-year GPA greatly influences final-year CGPA meanwhile, demographic characteristics have no significant correlation with students' final-year CGPA. Finally, the correlations drawn from this study indicated that first-year GPA had a strong positive relationship with final-year CGPA. Therefore, the students should be properly guided, University administrators, Faculty members, policy-makers and other stakeholders should effectively develop a monitoring blueprint for students' academic progress as poor performance has severe consequences on students, teachers should inculcate effective learning culture among students, while government and its supervisory agencies should provide adequate teaching and learning resources, create enabling learning environment for effective service delivery that focuses on improving students' performance in Engineering.","PeriodicalId":72922,"journal":{"name":"Engineering reports : open access","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eng2.12766","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135885536","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}

To achieve this a descriptive research approach was used, guided by a systematic review of literature from 2016 to 2022. Among the 4037 studies initially identified, only 69 were deemed relevant. Meta-synthesis was then used to systematically identify, categorize, and quantify fundamental constructs inherent in the models from the relevant literature. As a result of this process, 406 constructs were identified across six thematic categories. These were subsequently integrated to develop a conceptual model that can be used to coordinate strategies to harness the potential of the 4IR towards a future-ready business. Findings show that the role of technology adoption remains pertinent in the ever-digitized world in which businesses operate and certain constructs are key to explain, support, and predict enterprise-wide adoption in the 4IR paradigm. Future studies can expand and test the model to promote digital fluency required by business constituents, noting differences across sectors.","PeriodicalId":72922,"journal":{"name":"Engineering reports : open access","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eng2.12762","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136071144","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}
