As a result, this research creates a novel mathematical compartmental dynamical model that, under both fixed and dynamic size network assumptions, can be utilized to precisely predict malware outbreaks. The modeling processes divided the network into seven distinct states and considered the diverse ways that users of the internet interacted with potentially hazardous links. The Hilfer-Katugampola fractional operator was employed to obtain the intended varied states of networks. The existence, uniqueness, equilibrium, and stability of the provided models are thoroughly examined. Then the best control plan is implemented for every network topology. The controllers' objectives are to minimize the costs of data loss due to infections, malware tracing, and public awareness improvements.

The nonlinear partial differential equations that govern the system are converted into ordinary differential equations using a similarity substitution. These changed equations are subsequently solved numerically using the Bvp4c method. A thorough analysis is conducted, comparing the current findings with previously published publications, resulting in a remarkable level of achievement. The implications of gyrotactic microorganisms are incorporated into the model that is used to describe the bioconvection. Given the conditions of convective heat with zero heat and mass flux, it is presumed that the surface of the rotating is prepared for the possibility of nanofluid wall suction or injection. The main finding of the current work is radial and axial velocity is depreciated with enlarging values of Deborah number while rise with stretching variable.

It aims to enhance human well-being, particularly within office environments, ultimately influencing performance and corporate success. In the era of globalization, where office spaces play a pivotal role, the interplay between office design, occupant well-being, and performance cannot be underestimated. Several factors are integral to the success of office design, including lighting, color schemes, ergonomic furniture, and construction materials. A well-designed office should not only facilitate work but also lower stress levels, boost motivation, and promote physical health among its users. This academic study delves into the identification of biophilic design elements that contribute positively to the office experience. It commences with a comprehensive literature review on biophilic design principles and their components. These principles are then transposed into the realm of office design, forming the basis for an expert evaluation survey. The survey findings highlight three paramount biophilic design elements for integration into office spaces: access to natural light, the use of evolving natural materials, and the provision of a nature view. Interestingly, participants with expertise in landscape architecture and biophilic design place higher importance on incorporating natural elements into their office designs. This research emphasizes the pivotal role played by biophilic design in shaping corporate environments, rendering them conducive to work, while concurrently promoting the wellbeing and productivity of their inhabitants.</p></div>","PeriodicalId":48648,"journal":{"name":"Ain Shams Engineering Journal","volume":"15 10","pages":"Article 102962"},"PeriodicalIF":6.0,"publicationDate":"2024-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S209044792400337X/pdfft?md5=9aa7722bbfcb37291dbad57595232521&pid=1-s2.0-S209044792400337X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141703827","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}
