X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray (EDX), and a vibrating sample magnetometer (VSM) were used to characterize the structural, morphological, and magnetic properties of ferrite powders. The XRD measurements showed crystallite sizes ranging between 24 - 28 nm. The FE-SEM images show the presence of agglomeration as well as a non-homogeneous distribution of the samples. On the other hand, the stoichiometry of the reactant solutions that were used is in close agreement with the elemental analysis that was obtained from EDX showing that the composition was as expected. Manganese ferrite showed a decrease in magnetic parameters on magnesium doping, which was further enhanced in (Ni,Co)xMn0.25-xMg0.75Fe2O4 nanoparticles upon replacement of nonmagnetic manganese ions for nickel and cobalt ions. Results indicated that Ni-Co-Mn-Mg ferrite nanoparticles’ crystal morphology, structural, and magnetic properties were significantly influenced by the amounts of nickel and cobalt content.","PeriodicalId":140467,"journal":{"name":"Academic Science journal","volume":" 47","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141367844","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}

They are considered a necessity for a comprehensive understanding of human mobility. According to a robust tracking system of the human body, locating and tracing the human body in practical applications are challenging due to the enormous number of deformations and variations in body parts, postures, skin colures, lighting conditions, and clothes. To reduce complexity, several earlier works have concentrated on specific issues, such as face recognition, hand motion recognition, and mark recognition. The researchers agreed that the most previous approaches presume that people act while standing. Focusing on the detection and tracking of the human body, and the other component focusing on the detection and analysis of human action, the suggested system is based on the integration of tracking with the study of human activities through movement. And use YOLOV5s algorithm for detection and tracking , the result achieve by this algorithm and proposed system mAp 99%. That is replacing typical processing procedures like roboflow with an alternative that can function without the Internet. The proposed system is based on ten classes that contain a collection of overlapping verbs and can operate on photos, videos, and real-time systems.","PeriodicalId":140467,"journal":{"name":"Academic Science journal","volume":"75 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139326186","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}
