Since the last decade, cloud-based electronic health records (EHRs) have gained significant attention to enable remote patient monitoring. The recent development of Healthcare 4.0 using the Internet of Things (IoT) components and cloud computing to access medical operations remotely has gained the researcher's attention from a smart city perspective. Healthcare 4.0 mainly consisted of periodic medical data sensing, aggregation, data transmission, data sharing, and data storage. The sensitive and personal data of patients lead to several challenges while protecting it from hackers. Therefore storing, accessing, and sharing the patient medical information on the cloud needs security attention that data should not be compromised by the authorized user's components of E-healthcare systems. To achieve secure medical data storage, sharing, and accessing in cloud service provider, several cryptography algorithms are designed so far. However, such conventional solutions failed to achieve the trade-off between the requirements of EHR security solutions such as computational efficiency, service side verification, user side verifications, without the trusted third party, and strong security. Blockchain-based security solutions gained significant attention in the recent past due to the ability to provide strong security for data storage and sharing with the minimum computation efforts. The blockchain made focused on bitcoin technology among the researchers. Utilizing the blockchain which secure healthcare records management has been of recent interest. This paper presents the systematic study of modern blockchain-based solutions for securing medical data with or without cloud computing. We implement and evaluate the different methods using blockchain in this paper. According to the research studies, the research gaps, challenges, and future roadmap are the outcomes of this paper that boost emerging Healthcare 4.0 technology.

Multipoint optimal minimum entropy deconvolution adjusted (MOMEDA) is a powerful method that can extract the periodic characteristics of signal effectively, but this method needs to evaluate the fault cycle a priori, and moreover, the results obtained in a complex environment are easily affected by noise. These drawbacks reduce the application of MOMEDA in engineering practice greatly. In order to avoid such problems, in this paper, we propose an adaptive fault diagnosis method composed of two parts: fault information integration and extracted feature evaluation. In the first part, a Teager energy spectrum amplitude factor (T-SAF) is proposed to select the intrinsic mode function (IMF) components decomposed by ensemble empirical mode decomposition (EEMD), and a combined mode function (CMF) is proposed to further reduce the mode mixing. In the second part, the particle swarm optimization (PSO) taking fractal dimension as the objective function is employed to choose the filter length of MOMEDA, and then the feature frequency is extracted by MOMEDA from the reconstructed signal. A cyclic recognition method is proposed to appraise the extracted feature frequency, and the evaluation system based on threshold and weight coefficient removes the wrong feature frequency. Finally, the feasibility of the method is verified by simulation data, experimental signals, and on-site signals. The results show that the proposed method can effectively identify the bearing state.

China's rapidly growing economy, population, and energy consumption are all threatening its future environmental sustainability. China faces many ecological challenges, and its reliance on coal is at the heart of most of the country's ecological troubles. Most of China's air pollution emissions come from the industrial and electricity sectors, and the human health costs of China's air pollution are very high. China is the largest global polluter, with more than 25 per cent of total global carbon dioxide (CO2) emissions, green development could help mitigate climate change and enhance global welfare. Over the past decades, the demand for energy sources has increased by 150% in China, which has made China among the most energy-consuming countries. Most of China's energy consumption comes from coal energy, which accounts for about 78% of all energy sources in China in 2011. China is one of the world's largest wind energy sources, according to data released by the World Wind Energy Association (WWEA), with about 34% of the world's wind energy sources. According to the road map implemented by the Chinese government by exploiting and generating wind energy sources and benefiting from the rapid economic development that China witnessed late, according to this plan by 2020, China is expected to produce about 250 gigawatts (GW). By 2030, production may reach 400 GW of electrical energy generated from wind energy, and by 2050, production may reach 1,000 GW.

The models, simulation, and validation were presented during the last decade over various moving particle investigations with thermal convection and disclosed the challenges as well. The present work provides the simulation and validation of the grinding mechanism of high-temperature nickel-based alloy with single abrasive grain. Several nickel-based alloys provide better performances for temperatures above 1000 °C and those suited for extremely difficult conditions as well. In this study, we simulate and analyze the grinding mechanism of high-temperature nickel-based alloy using single abrasive grain cutting. Using a grinding, it introduces variation in friction coefficient as per the variations of the grinding parameters. The grinding force system of single abrasive grain is designed and simulated to investigate high-temperature nickel-based alloy using various grinding conditions like particle settling modes such as rolling, horizontal, and vertical with thermal convection. The multi-grid finite element fictitious boundary method (FEM-FBM) is used to simulate and study the grinding mechanism of high-temperature nickel-based alloy in terms of fluid-particle sedimentations. The material used for this simulation study is Inconel 718 alloy. The simulation results investigate the various grinding force conditions of high-temperature nickel-based 718 alloys using the dimensional physical parameters and numbers such as Prandtl number and Grashof number. Finally, the simulation results were validated with a conventional FEM model.
