Methods: A field shaping technique based on a convex optimization method is proposed, capable of increasing the field level inside a breast-emulating stratification. Results: The theoretical results are numerically validated via the design and simulation of two circularly polarized antennas. The experimental validation of the designed antennas, using tissue-mimicking phantoms, is provided, being in good agreement with the theoretical predictions. Conclusion: The possibility of focusing, within a lossy medium, the electromagnetic power at millimeter-wave frequencies is demonstrated. Significance: Field shaping can be a key for using millimeter waves for breast cancer detection.

A field focusing technique based on a convex optimization method is proposed, capable of increasing the field level inside a breast-emulating stratification. A focusing technique based on convex optimization has been used here to increase the penetration in breast cancer imaging scenarios at millimeter waves. Significant enhancements of the field level inside a breast model have been achieved by employing focused apertures. The key challenge in cancer detection is how to classify tumors into malignant or benign machine learning techniques can dramatically improves the accuracy of diagnosis. As the methods itself show that it’s much complicated in designing and implementation. The data visualization process itself is a complicated process which can generate false results if the image has noise, so the result won’t be correct. It usually contains two major steps but the further steps are much similar to the above methods ,which makes it further more complicated as it including converting patched images to real images which makes the result inaccurate in diagnosis.","PeriodicalId":505677,"journal":{"name":"4","volume":"75 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139183216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Analyzing Corporate Social Responsibility Performance with the Weighted Product Model Method","authors":"M. Neela","doi":"10.46632/jbab/2/4/1","DOIUrl":"https://doi.org/10.46632/jbab/2/4/1","url":null,"abstract":"Corporate Social Responsibility (CSR), frequently abbreviated as CSR, is set to assume a crucial role in corporate reporting. It has become customary for all companies to establish CSR policies and create annual reports outlining their CSR activities. This approach aids in distinguishing between socially responsible behaviors and those lacking in social responsibility, simplifying their identification. Presently, CSR is recognized as a sophisticated and globally accepted concept that has systematically evolved and developed. It has emerged as a universally acknowledged language and perspective that is increasingly gaining significance. In today's context, stakeholders are expected to prioritize more than just profit generation and compliance with legal requirements; companies are also anticipated to demonstrate a commitment to business growth alongside their CSR endeavors. CSR has now become an integral aspect of modern business operations. Regarding its social impact, CSR research serves as a tool to understand how businesses influence society and the contributions they make. This research investigates how businesses champion sustainable practices, address social and environmental issues, and contribute to enhancing local communities. By scrutinizing CSR initiatives and their outcomes, research sheds light on the positive influence corporations can have on society. Stakeholder engagement is a central focus of CSR research, underscoring the importance of involving diverse stakeholders such as employees, customers, suppliers, local communities, and investors. This study examines how businesses engage with and react to these stakeholders, aiming to foster collaboration, transparent communication, and the establishment of trust. By nurturing stronger relationships and exploring effective stakeholder engagement strategies, businesses can enhance their social acceptance and credibility. Sustainability stands as a central pillar of CSR research, significantly contributing to the advancement of sustainable business practices. This research explores how companies integrate resource efficiency, environmental considerations, and measures to address climate change into their day-to-day operations. By identifying successful sustainability initiatives, CSR research helps shape best practices and facilitates the transition toward a more sustainable economy. The Weighted product model (WPM), initially introduced by Deng to tackle challenges in Multiple Criteria Decision Making (MCDM), provides a framework that examines the sequential relationships, data types, and geometric patterns among measurable impacts in a communication evaluation model. In this specific context, the alternatives being considered are Community relations, Diversity aspects, Employee relations, Ecological environment, and Product aspects. The evaluation parameters include Ownership by family, Ownership by founder, Ownership by mutual funds, Ownership by banks and insurance firms, Ownership ","PeriodicalId":505677,"journal":{"name":"4","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139320478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We employ a comprehensive methodology that includes the development of fuzzy models, integration with existing physical models, and a combination of simulation and experimental studies. Our findings reveal that fuzzy logic-based models outperform classical deterministic models, particularly when handling uncertainties in initial conditions, damping, and external forces. The adaptability of fuzzy models to uncertainties is a key advantage, making them well-suited for complex and unpredictable physical systems. The integration of fuzzy logic components into existing models enhances modelling accuracy without necessitating major modifications. This research highlights the potential of fuzzy physics in advancing our understanding of complex physical phenomena and calls for further interdisciplinary exploration, robust mathematical formalism development, and philosophical inquiries into its implications.","PeriodicalId":505677,"journal":{"name":"4","volume":" 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141224297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
