Person Identification through Harvesting Kinetic Energy

Energy-based devices made this possible to recognize the need for batteryless wearables. The batteryless wearable notion created an opportunity for continuous and ubiquitous human identification. Traditionally, securing device passwords, PINs, and fingerprints based on the accelerometer to sample the acceleration traces for identification, but the accelerometer's energy consumption has been a critical issue for the existing ubiquitous self-enabled devices. In this paper, a novel method harvesting kinetic energy for identification improves energy efficiency and reduces energy demand to provide the identification. The idea of utilizing harvested power for personal identification is actuated by the phenomena that people walk distinctly and generate different kinetic energy levels leaving their signs with a harvested power signal. The statistical evaluation of experimental results proves that power traces contain sufficient information for person identification. The experimental analysis is conducted on 85 persons walking data for kinetic power signal-based person identification. We select five different classifiers that provide exemplary performance for identifying an individual for their generated power traces, namely NaiveBayes, OneR, and Meta Bagging. The experimental outcomes demonstrate the classifier's accuracy of 90%, 97%, and 98%, respectively. The Dataset used is publicly available for the gait acceleration series

Repellent potential of medicinal oils against Tribolium castaneum (Herbst) under laboratory conditions

Laboratory experiments were conducted to determine repellency of five local medicinal oils i.e., neem Azadirachta indica A. Juss., castor Ricinus communis L., rapeseed Brassica napus L., lettuce Lactuca sativa L. and chamomile Anthemis cotula L. against Tribolium castaneum Herbst, each applied at 0.1, 0.5- and 1.0-ml doses. A glass cylinder divided into A, B and C sections with one end close was used. Fifty grams of wheat flour was placed at A and C ends. Twenty freshly emerged T. castaneum was released at the center of cylinder (B). The data was recorded after one-, two- and three-days to count number of T. castaneum at A and C for calculating percentage repellency. All the oils showed repellent potential against T. castaneum as their repellency increased with dose and time exposure. After three days, 100% repellency of T. castaneum was recorded in 0.5- and 1.0-ml doses of neem oil, followed by 6.67±3.33% repellency at 0.1 ml neem oil. After three days, the maximum repellency of T. castaneum in rapeseed, castor, chamomile, and lettuce was 86.67±7.26, 76.67±6.01, 76.67±4.41, and 75.00±7.64%, respectively, all recorded at 1.0 ml dose. Overall, neem oil exhibited significantly more repellency of T. castaneum, whereas castor, lettuce, rapeseed and chamomile were found non-significant with each other. Among doses, although highest repellency was recorded at 1.0 ml dose, but not significantly different from 0.5 ml dose of the individual oil. Therefore, 0.5 ml should be applied per 50 grams of wheat flour to get effective repellency of T. castaneum

Evolution of Wireless Communication to 6G: Potential Applications and Research Directions

Publisher Copyright: © 2022 by the authors. Licensee MDPI, Basel, Switzerland.The fifth-generation mobile network (5G), as the fundamental enabler of Industry 4.0, has facilitated digital transformation and smart manufacturing through AI and cloud computing (CC). However, B5G is viewed as a turning point that will fundamentally transform existing global trends in wireless communication practices as well as in the lives of masses. B5G foresees a world where physical–digital confluence takes place. This study intends to see the world beyond 5G with the transition to 6G assuming the lead as future wireless communication technology. However, despite several developments, the dream of an era without latency, unprecedented speed internet, and extraterrestrial communication has yet to become a reality. This article explores main impediments and challenges that the 5G–6G transition may face in achieving these greater ideals. This article furnishes the vision for 6G, facilitating technology infrastructures, challenges, and research leads towards the ultimate achievement of “technology for humanity” objective and better service to underprivileged people.Peer reviewe

Investigation of COVID-19 Impact on the Food and Beverages Industry: China and India Perspective

The sudden breakout of coronavirus disease (COVID-19) rapidly spread across the globe, leaving no country behind in being affected by the global pandemic in the year 2019–20. As COVID-19 commenced, within months two major Asian giants initiated the norms of social distancing and lockdowns in their societies. The indiscriminate nature of the current pandemic has not only impacted the health and quality of life of people but has also disrupted the global economy, supply chains, and countries all over the world. In food and beverage manufacturing industries, the unanticipated disruption has encumbered its lock on the global food supply chain and service sector as major cities shut down for several months in China and India. Human existence is dependent upon food, which renders energy for activity, growth, and all functions of the body. Although both China and India have shown eminent response to tackle the ongoing pandemic, the food supply chain remains vastly exposed to significant COVID-19 risks. This research primarily investigates the ongoing COVID-19 scenario in two major economies (China and India), delivering insight into the pandemic’s impact within the food and beverage manufacturing sectors, and explores the policies adopted and strategies undertaken for sustainability in food supply chains
