ABSTRACT
During the COVID-19 situation, various application-based work has to be studied and deployed to enable an IoT-based health framework. This work-based study may guide professionals in envisaging solutions to related problems and fighting against the COVID-19 type pandemic. Therefore, it identifies various technologies of IoT-based systems for monitoring pandemic situations. The mechanisms included in IoT like actuators, sensors, and the cloud-based network serves to help people from home rather than visiting the hospital occasionally. It uses optimizers to train the "noise” and "cough” target classes. Mel Frequency Cepstral Coefficients (MFCCs) were initially employed in several speech processing approaches, but as the discipline of Music Information Retrieval (MIR) advanced alongside machine learning, it was discovered that MFCCs could accurately capture timbre. Overall, the study finds different IoT applications for the medical area during the pandemic situation with detailed descriptions. In this present condition, advanced methodologies have given way to innovation in day-to-day life. The IoT-based model provides an enhancement of 98.8% with a minimum training loss of 0.15. The framework depicts the excellent working of the proposed framework, and a true positive value of around 96.6% is shown in the confusion matrix and a true negative rate of around 97% was illustrated using this model. By making it possible for the cost-effective fabrication of wearable sensors through printing on a variety of flexible polymeric substrates, the rapid advancements in solution-based nanomaterials presented a hopeful viewpoint to the field of wearable sensors. This review focuses on the most recent significant advancements in the field of wearable sensors, including novel nanomaterials, manufacturing techniques, substrates, sensor types, sensing mechanisms, and readout circuits. It concludes with difficulties in the subject's future application. © 2021 Journal of Robotics and Control (JRC). All rights reserved.
ABSTRACT
Smart surgery is a new way to utilize smart devices to change existing surgeries. Smart glasses can enhance the surgical procedure so that the patient can understand the procedure more intuitively. Surgery is for patients, and patient acceptance of extended reality surgery is the purpose of this study. This study uses the technology behavior model, which is more in line with the user's assessment of the acceptance behavior of the new technology. A triangulated research approach was used, which applies to this study for a specific patient population. Primary data were collected from hospitals through questionnaires and were statistically analyzed by CB&PLS-SEM multimodel using SmartPLS software. It was concluded that patients were influenced by operational emotional factors in undergoing extended reality surgery. The study provides a basis for future research related to the practical application of smart surgery from the patient's perspective in viewing and accepting surgery.
ABSTRACT
Multiple unfortunate accidents in hotels ranging from theft to crimes due to unsupervised access. This paper aims to implement a smart hotel access system based on high-security attributes using the NFC Host-Card Emulation application for authentication in hotels to replace the traditional access ways. Analysis of the technologies and market were made to enlarge the knowledge and benefits of the proposed application. A mixed-mode evaluation was introduced based on surveys and interviews in two different geographical areas. The proposed system is an anti-contagious and contactless technology of smartphone applications for a convenient safe visit. The highest positive responses regarding cost-effectiveness were from Le Quadri hotel oppositely Four Seasons Hotel had larger positive responses in regards the contactless technology. Moreover, both locations had the same average of 95% positive comments given the competency and trust the application provided for eliminating contagiousness of covid-19. © 2021 IEEE.
