As modern vehicular communication systems advance, the demand for robust security measures becomes increasingly critical. A misbehavior detection systems (MDS) is a tool developed to detect if a vehicular network is being attacked so that the system can take steps to mitigate harm from the attacker. Vehicular communication systems face significant risks from distributed denial of service (DDoS) attacks. During a DDoS attack, multiple nodes are used to flood the target with an overwhelming amount of communication packets. In this paper, we first survey the current MDS literature and how it is used to detect and mitigate DDoS attacks. We then propose a new distributed multilayer perceptron classifier (MLPC) for DDoS detection and evaluate the performance of the proposed detection scheme in vehicular communication systems. For the evaluations using simulations, two specific implementations of the attacks are conducted. Apache Spark is then used to create the distributed MLPC. The median F1-score for this MLPC method was 95%. The proposed method outperformed linear regression and support vector machines, which achieved 89% and 88% respectively, but is unable to perform better than random forests and gradient boosted trees which both achieved a 97% F1-score. Using Amazon Web Services (AWS), it is determined that model training and detection time are not significantly increased with the inclusion of additional nodes after three nodes including the master. © 2023 IEEE.

Smartphones as a means of communication are not only used to send and receive messages and make phone calls. Today's smartphones are also intended to store personal data and sensitive information hence it is vulnerable to be illegally accessed by others. Fingerprint as a biometric lock screen for smartphones can be trusted to ensure the security and privacy of smartphone users. A fingerprint is closely related to a user's identity. When using fingerprints, users provide their personal biometric pattern, unknowingly giving their privacy and making them vulnerable to unauthorized use of their biometric pattern. This study is designed to reveal the factors that influence users when using fingerprints as a smartphone lock, using eight variables adapted from previous research. The data analysis used is Partial Least Squares (PLS) analysis. The results of this study suggest that trust, attitudes, and perceived risk are the factors that influence users when using their fingerprint as a smartphone lock.

Power amplifiers that generate high-voltage is needed in high-frequency applications. Limited by semiconductor voltage rating, conventional power amplifiers generate high voltage through matching network with high voltage-gain. However, inductors used for matching network limit the power density of the power amplifier. Moreover, high-voltage-gain matching network requires high circulating current and degrades the efficiency of the power amplifier. This paper presents a compact series-stacked power-amplifier for high-voltage pulsed application. The proposed power amplifier is composed of power amplifier modules, which are combined by a parallel-in series-out air-core transformer for high voltage generation. The architecture stacks up voltage by combining voltage in series which eliminates the need of using high-voltage-gain matching network. The air-core transformer is designed and integrated on board for high power density and ease of prototyping. Moreover, a design methodology is proposed to utilize the leakage of the on-board air-core transformer in matching networks, which eliminates the need of discrete inductors. Finally, A 24 MHz compact power amplifier is built based on the proposed architecture and design methodology which generates more than 6kV output voltage. © 2023 IEEE.

As industrial systems become more complex and interconnected, diagnosing faults accurately and in real time has become increasingly challenging. This paper explores how combining artificial intelligence with digital twin technology can address these challenges. We focus on developing hybrid Artificial intelligence models that leverage diverse data sources to enhance fault detection and diagnosis, enabling secure and distributed diagnostics. Digital twins, virtual models of physical systems, are shown to enhance predictive maintenance and decision-making by providing real-time system insights. What sets our work apart is the way we integrate these technologies to create scalable, adaptive, and context-aware diagnostic solutions. We demonstrate the potential of this approach across applications such as smart grids, manufacturing, and autonomous systems. Our goal is to provide researchers and practitioners with a practical and forward-looking framework for developing intelligent, reliable fault diagnosis systems in today’s data-rich industrial environments. © 2013 IEEE.

Non-orthogonal multiple access is one of the best methods for addressing the needs of 5G wireless services (NOMA). The proliferation of mobile devices in recent years has increased the importance of cooperative spectrum sharing and utilization in wireless communication due to increases in the bit error rate (BER) brought on by collisions and interference. In this study, MIMO and Massive MIMO (M-MIMO) in the downlink (DL) NOMA power domain (PD) in conjunction with the Cooperative Cognitive Radio Network are proposed as two new ways for improving and evaluating BER in the 5G network (CCRN). Customers of NOMA compete for available channels on the CCRN in this first strategy. The second approach creates a dedicated channel for NOMA users. Three scenarios with varying distances, power location coefficients, and transmission power are used to evaluate the proposed methods in the MATLAB software program. It is assumed that four users will share a 90 MHz BW using QPSK modulation in all three scenarios. When evaluating the performance of the suggested system under the presumption of frequency-selective Rayleigh fading, concurrent interference cancellation (SIC) and unstable channel conditions are also considered. © 2023 IEEE.

Inverter-interfaced distributed energy systems have been spreading over low-voltage electric grids to achieve higher integration of renewable sources while offering adjustable controllability over power conversion. In addition, due to their remote control capabilities that support a networked system framework, such inverters play an essential role from the perspective of dispatchable microgrids. These are power systems of limited size incorporating information and communication technology infrastructures. By managing network-controlled inverters, it is possible to regulate the power dispatchability of microgrids, allowing them to flexibly exchange power with the upstream grid as needed flexibly. Nonetheless, the control modeling and stability concerns of inverters forming a networked system within such a perspective lack discussion in the literature. Hence, this paper proposes a generic system model for a dispatchable microgrid, considering that a central controller steers inverters under a networked control framework. Moreover, stability considerations are presented, highlighting the impact of communication delays on the microgrid operation and indicating that multiple aspects still need to be investigated in future research. © 2022 IEEE.

Planning ship routes that take into account meteorological and oceanographic conditions is a salient problem for both commercial and Naval applications. The A∗ algorithm is a very common method for finding the minimum cost path in a graph. Finding appropriate heuristics for a cost function is critical to the computational efficiency and memory requirements of the A∗ algorithm. We propose heuristic evaluation functions (HEFs) based on the minimum, mean, median, and mode of the cost function values over the reachable nodes given time constraints. Only the HEF based on the minimum is admissible, but we show that the other heuristics are able to find near-optimal solutions in substantially shorter times than the Dijkstra's algorithm, which does not use a heuristic. We evaluate these heuristics over many scenarios and show that overall the HEF based on the mean value performs the best. This HEF can be used in time-critical applications where an occasional loss of optimality is sacrificed for faster run time, such as real-time planning and control, or as part of a multi-objective shortest path algorithm for planning and execution. © 2023 IEEE.

Piezoelectric devices recently have emerged as a viable alternative to replace magnetics. However, their applications have primarily been focused on dc-dc converters that utilize off-the-shelf piezoelectric devices. This paper introduces a class-e power amplifier that utilizes a newly developed piezoelectric transformer (PT) capable of scaling different conversion ratios. The proposed PT comprises a vertically stacked substrate quartz with PZT pieces mounted on the top and bottom surfaces of the quartz. The conversion ratio of the proposed device structure is established based on the constitutive equations of piezoelectric materials, and a design methodology is presented to achieve different voltage gains based on corresponding device parameters. A prototype PT is fabricated and tested to validate the proposed structure. Finally, both a class-d and class-e power amplifier is developed and tested using the proposed PT to demonstrate its advantage. © 2023 IEEE.
