Each year, natural disasters result in substantial economic and human losses, underscoring the critical requirement for predictive systems capable of issuing timely alerts. Technology, particularly Artificial Intelligence (AI), plays a pivotal role in enhancing early warning systems (EWSs) for natural disasters. AI algorithms analyze extensive datasets from various sources - such as satellite imagery, weather data, and seismic activity - to deliver more precise and nearly real-time warnings for events like earthquakes, tsunamis, and floods. This paper proposes an AI-driven approach that utilizes wireless sensor networks (WSNs) strategically deployed in disaster-prone coastal areas to monitor seismic activity and oceanic disturbances. The system aims to detect anomalies indicative of tsunamis and earthquakes, offering an advanced EWS that enhances both the accuracy and timeliness of disaster warnings, thereby mitigating potential risks to vulnerable communities. Additionally, the paper explores opportunities for further refinement of these systems to better protect at-risk populations. © 2024 IEEE.

The reality that so many third-party applications for Android have security flaws that allow thieves access is one of the main drawbacks of using them. The primary cause of the compromise is that, when implementing the source code, the developer focused more on the application's functionality than on its confidentiality, integrity, and authentication. As a result, safeguarding sensitive data used by users of mobile applications became extremely difficult due to privacy breaches. This study looks at how to analyze Android code to identify the fundamental causes of vulnerabilities that are discovered in it. A Mobile Security Platform (MobSF) was utilized to perform comprehensive and dynamic evaluations of Android applications. This required looking at the source code-The code written by developers-As well as the binary code, which is the code that can be executed by devices. It also involved using a method called common weakness enumeration to find known vulnerabilities. Identifying vulnerabilities in the source code itself and any additional security holes in the application was the aim. Typically, the adversary inserts malicious strings and backdoors into the applications to gain access and steal sensitive data. MobSF is an Android app analysis tool with a graphical user interface. MobSF is an Android app analysis tool with a graphical user interface. Although it can analyze apps both statically (by analyzing the code) and dynamically (by running the app), our primary goal is to detect potential security flaws or weaknesses in the Java code that developers write. © 2024 IEEE.

This paper presents the algorithm and very-large-scale integration (VLSI) architecture of a high-throughput and highly efficient independent component analysis (ICA) processor for self-interference cancellation (SIC) in in-band full-duplex (IBFD) systems. This is the first VLSI architecture reported in the literature based on the state-of-the-art entropy bound minimization (EBM) approach. A novel ICA algorithm is presented in this paper with momentum gradient descent optimization. Simulation results show that the number of iterations for the proposed algorithm is significantly reduced compared to the conventional ICA algorithms. Furthermore, a novel early-distribution estimation scheme is proposed in the designed ICA processor to compute multiple distribution functions with low latency and low complexity. The processing flow and the efficiency for the hardware utilization are specifically designed so that the processing speed is maximized with minimum employment of hardware components. The proposed ICA processor is designed and implemented based on the application-specific-integrated circuit (ASIC) flow. The post-layout estimations show that compared with the conventional EBM-based scheme, the proposed design improves the throughput and efficiency by 30x. In addition, compared to prior designs shown in the literature, the proposed ICA processor also demonstrates a significant enhancement in terms of throughput and efficiency. © 1983-2012 IEEE.

Due to economic expansion, population growth, and technological improvements contribute to rising energy demand, the self-consumption of locally generated electricity from photovoltaic (PV) systems is becoming an important application area for stationary battery energy storage systems (BESS). The optimized load schedule and battery capacity were employed in this research to reduce the customer's total cost. In many articles, a PV-BESS system was optimized using various optimization approaches. The Earthworm Algorithm (EWA) in MATLAB was used as the optimization method. Based on the result, the EWA BESS size optimized is 20.36 kWh, the total optimized cost is 45% less than the total unoptimized value, and the total EWA optimized cost is 7% less expensive than the total Cuckoo Search Algorithm (CSA) optimized cost. It was proven using statistical tools that the overall cost of an optimized and unoptimized PV-BESS system differs significantly, whereas the total cost of an EWA optimized, and CSA optimized system does not differ much. © 2023 IEEE.

The simple design, tuning, and quick implementation of the PI family of controllers influence single-input, single-output (SISO) process control applications. However, with the industrial revolution, many industrial processes are now designed as multiple-input multi-output (MIMO) systems. The conventional controllers in this process produce suboptimal performance due to the system's non-linear, interacting, and dynamic nature. A linear matrix inequality-based fractional-order PI (LMIFPI) controller is proposed to address and overcome the quadruple-tank system's (QTS) interaction behaviour. In addition, the simulated annealing (SA) optimization algorithm is employed to determine the controller parameters using the integral square error (ISE) as the desired objective function. Experimental results indicate that the proposed controller achieved an almost 33.1652% faster settling time, a 7.651% reduction in overshoot, and a nearly 1.7% quicker rise time performance. © 2024 IEEE.

The insurance fraud claim detection is a critical task in the insurance industry. Various methodologies were proposed in terms of detecting fraud claims but the main thing is handling the proportionality between the fraud and non-fraud cases in the dataset before it was given to the model, in that case class imbalance may occur. Class imbalance where the number of fraudulent claims is significantly lower than legitimate claims which pose a challenge for accurate fraud detection. In this paper, we employed [Elreedy and Atiya in Inf Sci 505:32–64, 2019] Synthetic Minority Over-sampling Technique (SMOTE) algorithm to address the imbalance problem and enhance the performance of the fraud claim detection model. SMOTE is a popular technique for oversampling the minority class by creating synthetic samples that are similar to the existing minority class instances. By generating synthetic examples, SMOTE helps in balancing the class distribution and allows the model to learn from a more representative dataset. This technique is particularly effective when the available data is limited and insufficient to capture the complexities of the limited class. This process results in a larger and more balanced dataset, enabling the model to learn from a diverse range of fraudulent claim patterns. By applying SMOTE to our dataset, we are able to overcome the class imbalance issue and improve the performance of the fraud claim detection model. The resampled dataset provides a more accurate representation of the underlying distribution, leading to enhanced detection of fraudulent claims. We evaluate the performance of the model by measuring various metrics such as accuracy, precision, recall and F1-score. Our findings demonstrate the effectiveness of SMOTE in addressing class imbalance with improved random forest and LightGBM model for fraud claim detection process. The utilization of SMOTE contributes to better identification of fraudulent insurance claims, reducing potential losses an

In the field of wireless communications, the design and optimization of microstrip patch antennas play a crucial role in achieving efficient and reliable wireless connectivity. This paper is used to explore the performance characteristics of an inset-fed patch microstrip antenna employing various substrates. In this work, we investigate the impact of substrate selection on the antenna's performance in order to advance ourunderstanding and contribute to the development of more effective wireless communication systems. The effectiveness of inset-fed patch microstrip antennas using various substratematerials is examined in this proposed work. In order to fabricate antennas, a variety of substrates, including as FR-4, high-frequency dielectrics, are used. Gain, radiation patterns, and impedance matching are the main considerations. Engineers can choose the best materials and insights into how substrate features affect antenna characteristics. This proposedwork provides valuable suggestion for antenna design and optimization by investigating radiation patterns, gain, and return loss for each substrate using computer Simulation Technology (CST) Microwave studio. © 2024 IEEE.
