This paper presents the fusion of project‐based learning (PBL) and collaborative learning (CL) cohesively, coordinated with sensors and Bluetooth advancements, open‐source programming, and open‐source equipment devices, in a specific microcontroller and installed frameworks designing apply autonomy course for the elementary learners. The major purpose of this study is to evaluate the significance of integrating PBL and CL. The course creates capacities and abilities in critical thinking, problem‐solving, independent learning, collaboration, and specialized technical information. Since PBL alone does not guarantee profoundly talented cooperation, it was supplemented with CL. This structure coordinated course substance and understudy pragmatic accomplishment in a reenacted learning environment. The understudies built a line following and Bluetooth‐controlled robots by actualizing control programming on the “Arduino” open‐source platform, just as utilizing remote interchanges as Arduino offers an instinctive advancement condition and different equipment and programming resources that permit quick improvement of microcontroller‐based ventures. The basic findings of this study work reveal that teaching, learning, and student assessment processes can be improved by using PBL when integrated with CL. The research successfully extends onto another group of learners for preparing similar gadgets under different timelines. In addition, this paper also discusses upon the problem identification, selection of the equipment, circuit design, hardware mounting, and critical analysis of the results acquired from the course through the personal learning experience of the teachers as well as in the form of feedback from the two groups of young learners.
The growing use of nonlinear devices is introducing harmonics in the power system networks that results in distortion of current and voltage signals causing damage to the power distribution system. Therefore, in power systems, the elimination of harmonics is of great concern. This paper presents an efficient techno-economical approach to suppress harmonics and improve the power factor in the power distribution network using neural network algorithms-based Shunt Hybrid Active Power Filter (SHAPF), such as Artificial Neural Network (ANN), Adaptive Neuro-Fuzzy Inference System (ANFIS), and Recurrent Neural Network (RNN). The objective of the proposed algorithms for SHAPF is to reduce Total Harmonic Distortion (THD) within an acceptable range to improve system quality. In our filter design approach, we tested and compared conventional pq0 theory and neural networks to detect the harmonics present in the power system. Moreover, for the regulation of the DC supply to the inverter of the SHAPF, the conventional PI controller and neural networks-based controllers are used and compared. The applicability of the proposed filter is tested for three different nonlinear load cases. The simulation results show that the neural networks-based filter control techniques satisfy all international standards with minimum current THD, neutral wire current elimination, and small DC voltage fluctuations for voltage regulation current. Furthermore, all three neural network architectures are tested and compared based on accuracy and computational complexity, with RNN outperforming the rest.
The versatility of IoT devices increases the probability of continuous attacks on them. The low processing power and low memory of IoT devices have made it difficult for security analysts to keep records of various attacks performed on these devices during forensic analysis. The forensic analysis estimates how much damage has been done to the devices due to various attacks. In this paper, we have proposed an intelligent forensic analysis mechanism that automatically detects the attack performed on IoT devices using a machine-to-machine (M2M) framework. Further, the M2M framework has been developed using different forensic analysis tools and machine learning to detect the type of attacks. Additionally, the problem of an evidence acquisition (attack on IoT devices) has been resolved by introducing a third-party logging server. Forensic analysis is also performed on logs using forensic server (security onion) to determine the effect and nature of the attacks. The proposed framework incorporates different machine learning (ML) algorithms for the automatic detection of attacks. The performance of these models is measured in terms of accuracy, precision, recall, and F1 score. The results indicate that the decision tree algorithm shows the optimum performance as compared to the other algorithms. Moreover, comprehensive performance analysis and results presented validate the proposed model.
