However, ensuring the confidentiality, safety, and accurate prediction of energy consumption patterns in energy trading is a major challenge. To address these issues, an innovative solution that synergistically combines two cutting-edge technologies: blockchain and machine learning is proposed. This paper unveils a novel approach that harmoniously merges blockchain with the Recalling-Enhanced Recurrent Neural Network (RERNN) to revolutionize energy trading systems called ‘Blockchain-Enhanced Energy Trading with Recalling-Enhanced Recurrent Neural Network (BET-RERNN).’ Data from IoT-enabled smart devices is securely stored in blockchain blocks, ensuring data integrity and immutability. Blockchain’s decentralized nature creates a trust-less environment for energy trading, protecting the privacy and anonymity of participants while maintaining transparency. At the heart of our system lies the advanced machine-learning capabilities of the RERNN model. By processing the data stored on the blockchain, RERNN accurately predicts optimal power generation for small-scale energy systems, enabling smart communities to make informed decisions and optimize their energy consumption. The BET-RERNN scheme provides a plethora of strengths. First, participants can securely engage in energy trading without compromising sensitive information, fostering a more resilient and efficient market. Second, blockchain technology ensures that all energy-related data is protected from tampering and unauthorized access, ensuring system reliability and trust. An in-depth comparison of RERNN’s performance to traditional General Regression Neural Network (GRNN) and Gradient Boost Decision Tree (GBDT) methods is conducted. To verify the strategy’s effectiveness, MATLAB simulations are employed, demonstrating its real-world applicability and scalability. By combining blockchain and machine learning, a secure and privacy-preserving smart community is established, promoting sustainable energy practices for a greener future.KEYWORDS: Machine learningblockchainRecalling-Enhanced Recurrent Neural Networkpeer-to-peer energy tradingsmart communityinternet of Things Disclosure statementNo potential conflict of interest was reported by the author(s).","PeriodicalId":53436,"journal":{"name":"Smart Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135413040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, after using the CCD of experiments with three independent parameters with two levels, 20 flat PLA parts were produced with an FDM-based 3D printer. The mechanical behavior of the 3D-printed PLA part was investigated, and a model was developed from the three parameters to get the scientific information to optimize the responses. As a result, it was noticed that the layer thickness and nozzle temperature greatly influenced mechanical response. One of the major aspects of the coronary stent is the mechanical behavior should be in accordance with the medical requirements such as flexibility, which is very necessary to facilitate the placement of the vessel in the artery, and sufficient radial rigidity is also required to support the vessel. Based on this aspect the identified responses are tensile and flexural strength.KEYWORDS: FDMPLAtensile & flexural strengthresponse surface methodologycentral composite designoptimization AcknowledgmentsThe support from Amity University CAM LAB is gratefully acknowledged.Disclosure statementNo potential conflict of interest was reported by the author(s).Author(s) contributionAuthor(s) contribution in the manuscript entitled ‘Prediction of Mechanical Properties of FDM printed PLA parts using response surface methodology’ is as follows: Ayushi Thakur is a Research Scholar at Amity University Uttar Pradesh, Noida, India.

This paper proposes a novel one-dimensional hybrid chaotic map. The proposed map shows excellent chaotic properties when analyzed by bifurcation diagram, Lyapunov exponent & Shannon entropy. We further design an encryption strategy for data transfers between the smart meter and HAN devices. The proposed encryption scheme uses the existing lightweight key management in advanced metering infrastructure (LKM-AMI) architecture for data transfers, in which the encrypted data is transferred through an insecure channel and private keys are provided by trusted third party (TTP) through secure channels. The 2-way communication between HAN devices and the smart meter sends messages that are encrypted by using the proposed novel hybrid one-dimensional chaotic map. The encryption strategy mainly consists of three steps. In the first step, the seed and the control parameters are initialized. The second phase generates two intermediate keys using the proposed hybrid chaotic map. In the last phase, we encrypt the message by applying permutation followed by diffusion using intermediate keys. The proposed encryption strategy is resistant to various attacks.KEYWORDS: Smart gridsmart meterhome area networkchaos theoryAMIadvanced metering infrastructure Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementOn behalf of all authors, I, Lokesh Goel, declare that this article does not involve any generated or analyzed datasets.

Deploying an unsupervised Autoencoder algorithm for Intrusion Detection System (IDS) is computationally intensive for IoT devices with limited resources. In this work, we propose two distinct AI models using Post-Training Quantization; Quantized Autoencoder float16 (QAE-float16) and Quantized Autoencoder uint8 (QAE-uint8). QAE models are derived using Autoencoder models, which work on the assumption of generating high Reconstruction Error (RE) for anomaly data. Post Training Quantization includes pruning, clustering, and Quantization techniques. The proposed models were tested against the RT-IoT23 dataset, which includes normal and attack traces. This study is focused on the three major types of attacks, namely SSH brute-force, UFONet and DDoS (Distributed Denial of Service) exploitation. Since these attacks are the gateway for future exploitation. The model performance evaluated on IoT devices reveals that QAE-uint8 is the most efficient model by a wide margin, with average memory utilization decreased by 70.01%, memory size compressed by 92.23%, and peak CPU utilization decreased by 27.94%. Therefore, the proposed QAE-uint8 model has the potential to be used in low-power IoT Edge devices to detect anomalies.KEYWORDS: Anomaly detectionartificial intelligenceautoencodersIoTIDSpost-quantization training Disclosure statementNo potential conflit of interest was reported by the authors.","PeriodicalId":53436,"journal":{"name":"Smart Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135966219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, this article shows the comparative performance study of the proposed DWT matrices with conventional deterministic and random measurement matrices. Overall, the Battle1 wavelet-based measurement matrices demonstrate the enhanced performance against the db3, coif5, and sym6 based measurement matrices in terms of Percentage Root-Mean Squared Difference (PRD), Root Mean Square Error (RMSE), and Signal-to-Noise Ratio (SNR).

The transient case studies include the symmetrical and unsymmetrical fault at distribution line, intentional islanding, variation of power demand, switching of capacitor bank, addition of nonlinear load, motor starting condition, etc. This recommended methodology starts with generating the sampled voltage signals of three different phases of different locations, and each signal has been decomposed using discrete wavelet transform. The significant features are extracted from the computed energy values of detailed wavelet coefficient for co-training of fine K-nearest neighbor (KNN) and ensemble KNN classification in the following stage.

Approximately 10% (w/w) of glycerol is produced as a by-product in the manufacture of biodiesel. Through a catalytic oxidation reaction, glycerol can be converted to formic acid. In this study, glycerol was converted to formic acid as the main product by involving a heterogeneous catalyst of Cu-formate which was embedded in the ash of gelam wood (Melaleuca leucadendron). The catalyst was made with variations in the ratio of Cu-formate to gelam wood ash (GWA) = 0.125; 0.25; 0.50; and 0.75 (w/w). The catalysts were characterized by FTIR, XRD, SEM-EDX, and SAA. The Cu-formate/GWA catalyst was then tested for its activity on glycerol oxidation with various catalyst ratios, amount of catalyst (0.5–3% (w/w)), reaction temperature (50°−90°C), and reaction time (1–11 hours). The results showed that the yield of the products increased with increase in catalyst ratio. The optimal amount of catalyst was used at a concentration of 2% (w/w), a reaction temperature of 70°C, and a reaction time of 3 hours.

The diagnosis, treatment and aftercare of LC patients are exceedingly difficult and time-consuming throughout an epidemic due to a multitude of factors. In these situations, the care of LC patients using cutting-edge technologies offers the potential to enhance the diagnosis, treatment, and advancements using machine learning (ML) algorithms and artificial intelligence (AI). The researchers might be able to differentiate between lung problems brought on by the corona virus and those brought on by, for example, chemotherapy and radiation, using therapeutic and imaging data as well as ML techniques. AI ensures that the appropriate individuals are enrolled in LC clinical research more effectively and rapidly than in the past, when it was done in a conventional and time-consuming manner. To effectively treat cancer patients and find new, more potent treatments, it is critical to move past traditional research approaches and make use of artificial intelligence and machine learning (AIML). When applied to various patient populations, AI based algorithms can swiftly identify lung cancer CT scans with COVID-19-linked pneumonia and accurately distinguish non-COVID connected pneumonia, which is significant for thoughtful mechanisms of an outbreak that is significant to AI.

In this work, a multi-objective problem is formulated by combining the concept of demand side management (DSM) and Dynamic Economic Emission Dispatch (DEED). The multi-objective DSM – DEED problem is optimized by class topper optimization algorithm. In addition, an energy management algorithm (EMA) is proposed for optimal power utilization from various energy sources and to match the load demand with generated energy in presence of uncertainties of RESs. To get an accurate model, a random forest regression-based machine learning approach is considered in this paper to predict load demand, wind, and solar power on an hourly basis for a span of 24 hours. The objective here is to optimally schedule load consumption and power generation patterns simultaneously for a day to improve load factor, minimize operational cost, and maximize the profit of all the candidates of the electricity market simultaneously.
