Due to their numerous benefits, multi-modulation single-carrier pulse width modulation (MSC-PWM) approaches are becoming more prevalent in multilevel converter topology control systems. Compared to traditional multi-carrier PWM techniques, MSC-PWM methods present more straightforward real-time implementation, while achieving acceptable harmonic performances. However, their application remains limited to grid integration of photovoltaic converter systems, and no literature examines their suitability and effectiveness in multilevel converters supplying electrical machines. This paper uses the traditional and modified MSC-PWM methods to discuss the design and implementation of vector control for an induction motor fed by a multilevel cascaded H-bridge inverter. First, the vector control scheme is briefly introduced, and then each MSC-PWM method's implementation scheme is thoroughly described. Then, the effectiveness of the investigated MSC-PWM methods is evaluated through steady-state and dynamic computer simulation results. Finally, a performance comparison of different PWM methods is conducted based on the spectra and THDs of the motor voltage, current, and electromagnetic torque. According to the comparison study, the modified MSC-PWM technique is superior to the conventional MSC-PWM method in reducing the motor voltage THD by up to 30%, motor current THD by up to 40%, and subsequently reducing the torque ripple in the motor air gap. © 2023 IEEE.

For decades, satellites have facilitated remote internet of things (IoT) services. However, the recent proliferation of increasingly capable sensors and a surge in the number deployed, has led to a substantial growth in the volume of data that needs to be transmitted via satellites. In response to this growing demand, free space optical communication systems have been proposed, as they allow for the use of large bandwidths of unlicensed spectrum, enabling high data rates. However, optical communications are highly vulnerable to weather-induced disruptions, thereby limiting their high potential. This paper proposes the use of high altitude platform station (HAPS) systems in conjunction with delay-tolerant networking techniques to increase the amount of data that can be transmitted to the ground from satellites when compared to the use of traditional ground station network architectures. The architectural proposal is evaluated in terms of delivery ratio and buffer occupancy, and the subsequent discussion analyzes the advantages, challenges and potential areas for future research. © 2024 IEEE.

The Graph Laplacian Mixture Model (GLMM) allows to infer multiple underlying graph structures from multivariate time series data. Given its effectiveness in identifying brain states from brain activity measured by functional magnetic resonance imaging (fMRI), we adapt GLMM for block-structured datasets, where data is organized into communities with strong intra-community interactions and relatively weak inter-community connections. This modification of the GLMM enables to capture the intricate structure inherent to block-structured datasets, such as fMRI data that simultaneously covers brain and cervical spinal cord, which both come with different properties. By integrating the prior knowledge on community structure into the GLMM framework, we proposed an approach that more accurately reflects the hierarchical organization and interaction patterns present in these complex networks. This enhancement offers a powerful tool for studying networked systems with distinct community structures, improving our ability to interpret patterns and dynamics in neural data with natural sub-structural organization. © 2025 IEEE.

The wide applications of Electric Vehicles (EVs) for integration with renewable energy sources need high-power, isolated bidirectional converters (IBC). Bi-directional converters often suffer from high switching power losses leading to efficiency reduction. Therefore many topologies are proposed to achieve soft switching and increase the converter efficiency. Among the available topologies, resonant converters (RC), such as LLC, CLLC, CLLLC, and dual active bridge (DAB) converters, are widely employed for high-power conversion because of their superior efficiency and soft-switching capabilities. In this article, a comprehensive comparative performance analysis of different RC topologies is presented. Among these, the CLLLC converter topology has emerged as a promising solution, offering higher efficiency and an extended soft-switching range compared to other RCs. Performance validation of various RCs is obtained through an experimental prototype.

This paper presents a demand-side load management technique to manage the consumption in residential buildings by maximizing the user's satisfaction at minimal cost or within a predefined budget. The load satisfaction algorithm has been developed based on three postulations making it possible to quantify the satisfaction. This algorithm used a genetic algorithm (GA) and it offers a good convergence speed, great flexibility and good efficiency compared to conventional techniques. © 2022 IEEE.

The implementation of deep neural networks requires a significant amount of memory and computing power. As a result, they are often implemented in data centers or high-end computing devices such as GPUs. However, if the internal structure of an FPGA, particularly the LUTs, is considered, the FPGA implementation of these networks could prove to be more efficient. This paper presents an iterative pruning algorithm for removing unnecessary inputs from a layer's neurons so that they can be synthesized to a small number of LUTs in an FPGA. When the number of LUTs, throughput, and power consumption are considered, our design is $7.95 \times $ smaller, $1.66 \times $ faster, and $5.66 \times $ more power efficient than the baseline, with a 0.47% accuracy drop.
