    Design of Online Vitals Monitor by Integrating Big Data and IoT

    E. Afreen Banu1,*, V. Rajamani2

    Computer Systems Science and Engineering, Vol.44, No.3, pp. 2469-2487, 2023, DOI:10.32604/csse.2023.021332

    Abstract In this work, we design a multisensory IoT-based online vitals monitor (hereinafter referred to as the VITALS) to sense four bedside physiological parameters including pulse (heart) rate, body temperature, blood pressure, and peripheral oxygen saturation. Then, the proposed system constantly transfers these signals to the analytics system which aids in enhancing diagnostics at an earlier stage as well as monitoring after recovery. The core hardware of the VITALS includes commercial off-the-shelf sensing devices/medical equipment, a powerful microcontroller, a reliable wireless communication module, and a big data analytics system. It extracts human vital signs in a… More >

    Non-contact Real-time Monitoring of Driver’s Physiological Parameters under Ambient Light Condition

    Zhengzheng Li1, Jiancheng Zou2,*, Peizhou Yan1, Don Hong3

    Intelligent Automation & Soft Computing, Vol.28, No.3, pp. 811-822, 2021, DOI:10.32604/iasc.2021.016516

    Abstract Real-time and effective monitoring of a driver’s physiological parameters and psychological states can provide early warnings and help avoid traffic accidents. In this paper, we propose a non-contact real-time monitoring algorithm for physiological parameters of drivers under ambient light conditions. First, video sequences of the driver’s head are obtained by an ordinary USB camera and the AdaBoost algorithm is used to locate the driver’s facial region. Second, a face expression recognition algorithm based on an improved convolutional neural network (CNN) is proposed to recognize the driver’s facial expression. The forehead region is divided into three… More >

    Assessment of Effects of Concomitant Exposure to Sound, Heat, and Physical Workload Changes on Physiological Parameters in Five Different Combination Modes, a Controlled Laboratory Study

    Hossein Molaeifar1, Farahnaz Khajehnasiri2, Kiana Nikeghbal3, Zahra Zamanian1,*

    Sound & Vibration, Vol.54, No.3, pp. 139-148, 2020, DOI:10.32604/sv.2020.08810

    Abstract Exposure to sound, heat, and increased physical workload can change physiological parameters. This study was conducted to evaluate the effect of concomitant exposure to sound, heat, and physical workload changes on physiological parameters in controlled laboratory conditions. This experimental crosssectional study was conducted in 35 male university students with a mean age of 25.75 years and a mean BMI of 22.69 kg/m2 . Systolic and diastolic blood pressure and heart rate were measured after 15 min rest in the laboratory, 5 and 10 min after starting the experiment, and then after 20 min in controlled laboratory… More >

    PGPR inoculation improves growth, nutrient uptake and physiological parameters of Capsicum chinense plants

    Castillo-Aguilar C de la C1, JJ Zúñiga-Aguilar2, AA Guzmán-Antonio2, R Garruña3

    Phyton-International Journal of Experimental Botany, Vol.86, pp. 199-204, 2017, DOI:10.32604/phyton.2017.86.199

    Abstract The Habanero pepper (Capsicum chinense) is intensively cultivated in the Yucatan peninsula, México. Because of adverse environmental conditions, it required seeding in germination trays, from which six-week-old seedlings were transplanted to the soil. Adequate nursing and fertilization programmes were made to improve health and vigour before seedlings transplanting. During seed germination, we investigated the effects of inoculation with four plant growth-promoting rhizobacteria (PGPR) on growth, nutrient uptake and gas exchange of 8-week-old Capsicum chinense plants. Inoculation was made with Pseudomonas sp. -P61-, Pseudomonas sp. -A46-, Bacillus pumillus -R44-, and Paenibacillus polymyxa-BSP1.1-. The BSP1.1 strain produced the highest increase in… More >
