These devices can sometimes produce counterproductive effects, complicating the interaction between non-expert end users and the device itself. In this paper, we propose a simple, user-friendly, and cost-effective configurable smart mirror, which can display usefully relevant real-time information. This system is designed based on a low-cost Raspberry Pi paired with an LCD screen. The system can connect with a personal computer (PC) through the IEEE 802.15 wireless communication protocol. The preliminary results in this paper show the intuitive usability of the device in daily life.","PeriodicalId":500921,"journal":{"name":"Digital technologies research and applications","volume":"121 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141351750","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":"Analysis of the Interaction Effects of Electromagnetic Fields with Major Living Tissues—One Health Concept Numerical Evaluation Strategy","authors":"Adel Razek","doi":"10.54963/dtra.v3i2.243","DOIUrl":"https://doi.org/10.54963/dtra.v3i2.243","url":null,"abstract":"The well-being and sociability of individuals have always been part of modernity. The development of new technologies that meet these aspirations is receiving increasing attention. Thus, strengthening the desired objectives of these technologies and minimizing their undesirable side effects is the subject of growing commitment. The present contribution aims, in this context, to evaluate and analyze the desired and undesirable effects of the interaction of electromagnetic fields with living tissues in general. These are routines based on mathematical modeling reinforcing the expected functions as well as those of control and protection against undesirable effects. These adverse effects correspond to the “One Health” concept, which encompasses the health of animals, plants and humans, as well as ecological disorders created by human activity. First, in this article, the interactions of electromagnetic fields with tissues are analyzed, involving their thermal biological effects of desired and undesired exposures. The roles of blood and sap fluids in bio-affected tissues are then analyzed. Secondly, the equations governing electromagnetics and bio-heat, as well as their coupled solution are studied. Third, the thermal behavior of tissues and the adverse effects of exposure are examined. Next, monitoring and defending the effects of exposures are discussed. This contribution, supported by a review of the literature, illustrates routines for mathematical modeling of the generalized interaction of electromagnetic fields with living tissues.","PeriodicalId":500921,"journal":{"name":"Digital technologies research and applications","volume":" 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140988423","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}

In this study, an extended prosthesis control system is proposed which is able to recognise gesture intent motions alongside the prediction of an associated contraction force as part of an advanced pattern recognition system. As part of this research topic, this paper introduces the proposed control architecture and is based on the solving of the gesture recognition problem amidst varying contraction forces for a transradial amputee with a seemingly faint phantom motion.The work involves the application of a novel decomposition algorithm and the use of a set of computationally effective features, alongside the contrast of the recognition capabilities of the proposed approach using various classification models. The results show an enhanced recognition of gesture motion intent with the use of the decomposition method, despite the faint phantom motion signal from the amputee.","PeriodicalId":500921,"journal":{"name":"Digital technologies research and applications","volume":"217 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135155677","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}
