Standard ratio estimators are poor for estimating the mean of a finite population due to their complex relationships. This research provides an improved family of ratio estimators that combine power and logarithmic transformations within a simple random sampling (SRS) framework, leveraging auxiliary data to increase estimation accuracy. The proposed changes contribute to the linearization of complex relationships, the stabilization of variance, and the reduction of estimator bias, all of which improve predictive performance. The usefulness of these estimators is proven using solar radiation datasets, which exhibit nonlinearity due to temporal variations, spatial heterogeneity, and atmospheric impacts. Mathematical derivations and practical assessments show that the proposed estimators have lower mean squared error (MSE) and higher percentage relative efficiency (PRE) than classic ratio estimators. The findings emphasize the necessity of using auxiliary information in transformation-based estimators to improve solar radiation data processing, hence enabling more accurate solar energy forecasting, climate modeling, and sustainable energy planning in environmental and renewable energy research.</div></div>","PeriodicalId":16920,"journal":{"name":"Journal of Radiation Research and Applied Sciences","volume":"18 2","pages":"Article 101379"},"PeriodicalIF":1.7,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143529724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of the nonstationary and nonlinear characteristics, it is difficult to predict its future trajectory accurately using simple time series or econometric models.

This paper presents a novel convolutional neural network (CNN) for detection known as COCDNet and two sets of modifications to CNN models for identifying cecum CRC in computed tomography (CT) radiological scans. Before images are included in the architecture, they are preprocessed to reduce the noise. The data is then sent into a COCDNet model that holds 22 layers. On other hand, two types of transfer learning (TL) are used to four popular CNN models: DarkNet19, VGG16, VGG19, and AlexNet. The dataset comprises 1695 images of abdomen CT scans, categorized into two main classes as cecum cancer and normal images. COCDNet achieves the highest performance, proving an accuracy of 97.04%, an F1-score of 95.80%, and recall approaching 100%. These measures demonstrate that COCDNet is a dependable tool for early CRC diagnosis because it can both reliably detect cancer and reduce false positives.
