Effect of hydrodynamics on a copper-nickel alloy rotating disc electrode in a marine environment

Abstract: The impact of hydrodynamic conditions on the electrochemical corrosion behavior of a Cu90–Ni10 alloy in an artificial marine environment and a sulfide-contaminated marine environment in the absence and presence of 5-(3-aminophenyl)tetrazole (APT) is discussed. Electrochemical impedance spectroscopy, potentiodynamic polarization and cyclic voltammetry (CV) and surface analytical techniques, viz., X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), are applied to evaluate the APT performance. Both the Rct and Rfilm values are reduced with an increase in the rotation speed in sulfide-polluted marine water and without APT. Interestingly, in the presence of APT, in the absence and presence of sulfide, both the Rct and Rfilm values are increased enormously. Potentiodynamic polarization studies suggest that APT performs as a mixed inhibitor. XRD and XPS techniques suggest the presence of CuO, Cu2O, CuCl, CuS and Cu2S in seawater and sulfide-contaminated seawater in the absence of APT. However, the above products are completely absent in the presence of APT film.

Battling Fake News: A Survey on Mitigation Techniques and Identification

Abstract: Fake news are generally characterized as misdirected news, which are often constructed with a feeling of conviction and tricking people towards accepting a specific incident. Fake news spread widely due to its social associations. The multiplication of fake news via web-based media has opened up a new plethora for performing recognizable testing and regulation on fake news ideals and to alleviate its great influence on the popular hypothesis. Although different existing research works focuses on the distinguishing evidence obtained from fake news that depends on its substance or that abuses customer engagement with news via web-based media, there has been a growing enthusiasm on proactive advocacy methodologies in order to counteract the spread, deception, and its effect on society. This study describes the current topic of fake news and specifically presents the specialist difficulties related to it. This research work discusses about the existing strategies and procedures relevant to both DI and moderation by leveraging significant attention to the critical progress in each strategy along with their points of interest and constraints. Furthermore, the search was regularly limited by the nature of the existing datasets and their particular application settings. To mitigate this problem, this research work completely sort and summarizes the brand highlights obtained from the accessible datasets. Additionally, new exploration headings to further advance workable interdisciplinary agreements are also reported.

Suboptimal control of singularly perturbed multiparameter discrete control system

Abstract: Study of a generalized problem is very important in the sense it provides complete picture of the problem. Accordingly a generalized singularly perturbed multiparemter discrete control system is considered. An open-loop optimal control problem based on Pontriagin's Minimum Principle (PMP) is formulated. The resulting optimal control solution needs special numerical techniques as the system is highly stiff due to multitime scale nature of the system with n small parameters. Hence it is proposed to go for a suboptimal controller that mitigates this problem. Singular Perturbation Method (SPM) that reduces the order and removes the stiffness of the system is an ideal choice for this problem. Here a generalized SPM is presented for this multiparameter problem. The SPM consists of an outer, n initial boundary layer correction (BLC) solutions and n terminal BLC solutions for this problem. An example is provided. The numerical results substantiate the proposed suboptimal controller.

Front-End IoT Application for the Bitcoin based on Proof of Elapsed Time (PoET)

Abstract: There are some registry agreements that may be appropriate for the Internet of Things (IoT), including Bitcoin, Hyperledger Fabric and IOTA. This article presents quickly and examines them in terms of the progress of Internet applications. Block-dependent IoT applications can consolidate the chain's rationale (smart contracts) and front-end, portable or front-end web applications. We present three possible designs for BC IoT front-end applications. They vary depending on the Bitcoin block chain customer (neighborhood gadget, remote server) and the key location needed to manage active exchanges. The vital requirements of these projects, which use Bitcoin to organize constructive exchanges, are the volumes of information, the area and time of the complete block and block block, and the entry of the Bitcoin store. The implications of these surveys show that it is unlikely that a full Bitcoin distributor will continue to operate reliably with a mandatory IoT gadget. Then, designing with remote Bitcoin customers is, in all respects, a suitable methodology in which there are two minor alternatives and vary in key storage / management. Similarly, we recommend using the design with a unique match between the IoT gadget and the remote blockchain client to reduce system activity and improve security. We hope you also have the ability to operate with versatile verses with low control and low productivity. Our review eliminates the contradictions between synthesis methodologies, but the final choice for a particular registration agreement and the original technique completely depends on the proposed use case.
