This article proposes the implementation of a captive portal system on a microcontroller to assess users' maturity regarding the safe use of public Wi-Fi networks. The use of public Wi-Fi networks has become increasingly common in places like cafes, airports, shopping centers, and hotels. However, many users are unaware of the risks associated with using these unsecured networks, such as personal information theft, privacy invasion, and cyberattacks. This study aims to utilize a microcontroller to generate a signal mimicking a known public network, where, upon user login, an educational authentication portal will be displayed. This portal will not only provide information about security risks but also evaluate the users' maturity level in adopting safe practices on public Wi-Fi networks, offering guidelines on how to protect their data and devices. © 2024 IEEE.

Lead-free perovskite materials have emerged as the most feasible option for photovoltaics to address the issue of toxicity and better performance. This study aims to design and enhance the performance of lead-free methylammonium (MA) and formamidinium (FA) compound (FAMASnGeI3)-based flexible perovskite solar cell (FPSC) by utilizing the solar cell capacitance simulator 1-D (SCAPS-1D). The optimization of various geometrical parameters and charge densities of the absorber and charge transport layers show the improvement in power conversion efficiency (PCE). We have obtained Voc of 0.87V, Jsc of 45.7 mA/cm2, fill factor (FF) of 75.3%, and PCE of 29.9%. The obtained results were compared with similar existing research based on various absorber layers. It was found that the selected absorber layer improves the performance of FPSCs. © 2022 IEEE.

In this generation, deep learning techniques are widely used for sign language prediction. In this paper, a deep learning model is proposed for American sign language detection using webcam images and transfer learning. The particular model is designed for a real-time sign language detection. The author claims 98% of accuracy for this designed model, when trained with a total of 15 images for each gesture. Jupyter notebook is used as the environment for working out this research. Cuda, cudnn graphic processor upgraders are also utilised in this research for training the model. To make real-time detections easy, a local environment is used rather than a cloud system for implementing the code. The main aim of this research work is to create a model in order to identify and detect the sign language alphabets and some very frequently used gestures. The model is designed based on deep learning by using the convolutional neural networks and single shot detector algorithm to surpass the difficulty that is faced by the speech impaired and normal people. ©, Engineers Australia.

A significant drive is currently underway to integrate an ever-increasing number of distributed energy resources into the power system, termed the "Smart grid." For effective operation of the grid at all levels, it is required to adopt well-advanced software and hardware components. In any instance, the entire process is time consuming and only provides a partial view of the system's behavior under various nominal and fault operating conditions. The Hardware-In-the-Loop (HIL) approach is widely interpreted as a valuable prototype tool for Grid Connected Converter (GCC) development and validation at both the converter and power grid at all levels. The paper is based on the Controller - HIL (C-HIL) approach that demonstrates the Typhoon HIL control center which provides remarkable efforts to test and optimize the GCC control loops. It includes the test and optimization of the converter harmonic performance, optimization of the grid filter, injection of active and reactive power into the grid and analysis of various ride through faults in the system. It also includes the design of the current controller, Total Harmonic Distortion (THD) analysis and comparison of the model with and without implementing the maximum power point optimization technique. © 2023 School of Science, IHU.

Microgrids are essential to advancing smart grids, improving cost reduction, reliability, and increased penetration of distributed generation (DGs) systems. However, integrating the bi-directional converter and distributed energy resources (DERs) poses challenges to protection coordination. Thus, a robust protection approach is essential to address the complexities associated with microgrid systems. This article proposed a novel fault detection method, incorporating superimposed positive sequence impedance to detect faults within a microgrid system. The Δ Z method is numerically defined as the ratio of the sum of superimposed positive sequence impedance at the sending and receiving end of the feeder to the larger one amongst both of them. The internal and external faults are identified using the threshold value. A Δ Z parameter-based method is verified across various scenarios, including numerous fault types, locations, fault resistances, and operating conditions such as capacitor switching and load changes. Furthermore, the Δ Z approach displays robust performance under adverse conditions, including noise, sampling frequency variations, and simultaneous and evolving faults. The proposed scheme's effectiveness has been validated using MATLAB/SIMULINK software. This research highlights the perspective of the Δ Z technique as a reliable tool for enhancing fault detection in microgrid systems. © 2024 IEEE.

In actual practice, the most demanded agricultural loads (MDAL) are not being taken care of due to the scheduled power supply methodology practised by the present power distribution companies. Consequently, seasonal cultivations are affected due to insufficient availability of power supply. In this paper, the furnished result of a walk survey performed within an agricultural predominant area located in the vicinity of 33 kV/11 kV 5 MVA substation sited at lat. 13.62°N, long. 79.24°E and alt. 256 m confirms the above statement, i.e. about 62.12% of farming is affected due to insufficient availability of power supply. To address the concerns of the non-consideration of MDAL within the aforesaid expanse, a solar power generator of appropriate size, 103kWp derived based on the level of mismatch power attained by using ETAP software is proposed to erect near the utility grid and feed MDAL. Also, as a contribution, trio-lattice load scheduling methodology is introduced and applied to effectively utilise the generated electricity by scheduling the agricultural load points countered following the possible solar energy generation. Performance assessment indices: ADI, ERoS and ARoS are introduced to reconcile the effective utilisation of generated electricity by the proposed load scheduling methodology. The derived results and arrived performance assessment indices confirm that the proposed scheduling methodology could effectively utilise the solar energy resource and the concern system caters to the necessity of pleading irrigation. © 2023 Informa UK Limited, trading as Taylor & Francis Group.

Data selection can be used in conjunction with adaptive filtering algorithms to avoid unnecessary weight updating and thereby reduce computational overhead. This paper presents a novel correntropy-based data selection method as an alternative to conventional data selection mechanisms based on squared error values. We developed a variable correntropy sensing algorithm to maximize the instantaneous correntropy function for the Gaussian kernel function to mitigate the impact of impulse noise and other forms of noise that can be disregarded in data selection. The proposed data selection mechanism can be implemented with any adaptive filtering algorithm. In simulations, the proposed method (implemented with the least mean squared algorithm) outperformed comparable error-based data selection schemes in terms of hit rate and miss rate, and the resulting weight updating ratio was close to the expected weight updating ratio. © 2023 IEEE.

A Novel Access Point Deployment Framework for mmWave Cell-Free Massive MIMO Networks

引用

IEEE Transactions on Wireless Communications 2025年第6期24卷 4581-4597页

Millimeter-wave network deployment is an essential and ongoing problem due to the limited coverage and expensive network infrastructure. In this work, we solve a joint network deployment and resource allocation optimization problem for a mmWave cell-free massive MIMO network considering indoor environments. The objective is to minimize the number of deployed access points (APs) for a given environment, bandwidth, AP cooperation, and precoding scheme while guaranteeing the rate requirements of the user equipments (UEs). Considering coherent joint transmission (C-JT) and non-coherent joint transmission (NC-JT), we solve the problem of AP placement, UE-AP association, and power allocation among the UEs and resource blocks jointly. For numerical analysis, we model a mid-sized airplane cabin in ray-tracing as an exemplary case for IDS. Results demonstrate that a minimum data rate of 1 Gbps can be guaranteed with less than 10 APs with C-JT. From a holistic network design perspective, we analyze the trade-off between the required fronthaul capacity and the processing capacity per AP, under different network functional split options. We observe an above 600 Gbps fronthaul rate requirement, once all network operations are centralized, which can be reduced to 200 Gbps under physical layer functional splits. 2002-2012 IEEE.
