However, with the development of the Internet of Things (IoT), the number of smart applications and interconnected devices is increasing day by day. Deep Learning (DL) method has become necessary to process the large amount of raw data collected and to further improve intelligence and application capabilities. It is seen that the majority of researchers focus on action detection. Standard Deep Learning techniques are difficult to use in IoT devices as Deep Learning applications require high CPU, RAM and storage. In this study, an action detection technique has been developed directly on the edge device by enabling the use of deep learning techniques in IoT devices. This technique, as a representation of neural networks, divides it into on-board computers. Visual action detection is one of the critical components of a smart city. High processing capacity and storage requirements severely limit comprehensive and precise monitoring within the IoT and edge computing framework. The structure proposed in this paper suggests the deployment of micro deep learning algorithms to the latest IoT and embedded devices, including the utilisation of minimal computing resources such as processor, power and memory, with a contribution to IoT and embedded device activities in action detection. The systematic analysis shows that many IoT devices can be applied to the proposed optimisation design.

Additionally, the control parameters of the Mahafzah controller are adjusted using the new hybrid optimization model to improve the system's response time. The proposed hybrid technique is the hybrid methodology of Artificial Gorilla Troops Optimizer (GTO) and Tree Seed Algorithm (TSA) and hence it is named as GTO–TSA technique. Finally, the proposed system's performance characteristics are examined and contrasted with those of traditional optimization algorithms. At that point, the performance of the suggested technique has been tested in the MATLAB program and is in contrast with that of other methods already in use. The proposed method outperforms existing algorithms across a wide range of input voltages, with a power factor ranging from 0.98 to 0.995 and %THD (Total harmonic distortion) with lower values ranging from 1.6 to 1.15.

This survey paper elaborates on a step-by-step procedure for the wave variable approach for filter design with mathematical analysis. In addition, this work specifically focuses on developing WAF designs using different active blocks. Higher-order WAF designs using modern active blocks are well recorded in this survey paper for better visualization. In literature, third-order and fourth-order WAF implementations are mainly enriched. Hence, an OTA-based WAF is designed for lower- to higher-order filters, demonstrating their efficacy for multifunctional applications such as Wave Active Low Pass Filter (WALPF), Wave Active High Pass Filter (WAHPF), and Wave Active Bandpass Filter (WABPF) using OTA. Besides the theoretical foundations, simulation, and experimental test results are also performed to validate the workability of the OTA-based WAF. The frequency responses of WALPF, WAHPF, and WABPF are demonstrated for the second to sixth orders. The functionality of the OTA-based WAF is verified through frequency spectrum analysis and Monte Carlo simulations. This paper ultimately offers an extensive review of the WAF design process, including mathematical analysis and practical realizations.

Four identical crescent shaped radiating elements fed by utilising a microstrip feed line are designed by utilising the finite element method based high frequency structure simulator. The antenna parameters are characterised by utilising sets of real measurements to validate the antenna design and modelling. Chemical etching has been utilised for fabricating the quad port antenna on a FR4 substrate. Vector network analyser has been used for measuring the scattering and transmission coefficients. As well as, an anechoic chamber has been used for measuring the far field radiations and the gain of the antenna under test. The basic antenna is a part of the quad-port structure consists of a crescent shaped circular patch with a defected ground structure and are fed individually. MIMO ability is obtained by arranging 4 identical antenna elements in a successive rotational means for obtaining good polarization diversity. The connected ground between the antenna elements is obtained by subtracting 4 circular slots from the ground plane by maintaining a common ground plane. None of the slots touches each other thus ensuring the common reference while maintaining the inter isolation better than 15 dB. The antenna demonstrated maximum gain and efficiency of 4.59dBi and 90%, respectively besides attaining a 10-dB impedance bandwidth of 2–6.2 GHz and ECC < 0.01. Finally, the quad-port compact MIMO antenna is designed, simulated, fabricated and tested, it shows that the antenna is useful for n1, n40, n41, n77, n78 and n79 5G bands.

Notably, a unidirectional boost converter replaces traditional diode-bridge rectifiers, enhancing power factor, reducing harmonics, and regulating DC voltage.
