The technology of reconfigurable optical networks (RONs) is growing to be a promising solution to effectively cater to the rapidly increasing traffic generated by the digital society. Optical technology emerges as a viable alternative because to its capacity to offer a substantial bandwidth, little latency, and enhanced overall performance. Nevertheless, it is imperative to effectively manage the physical resources comprising a data center. This study provides an experimental demonstration of the RONs, which is enhanced by a control plane. The implementation relies on the monitoring of real-time network statistics. This enables the execution of various activities, including as network slice provisioning and reconfiguration, assignment of packet priority classes, and dynamic operations. These actions are performed to ensure the attainment of the desired Quality of Service level. The experimental results show the successfully implementation of RONs using Mininet Emulator and sFlow traffic monitoring technology. The results approve that optical datacenter has minimum delay with low OSNR even with long distance and fast switching time. © 2023 IEEE.

When synthesizing concurrent error-detection circuit using the signal's Boolean correction method, it is needed to drop the masking of errors at the checker inputs-the system "last watch-dog". This task appears since for the signal's correction from the diagnosis object, the distortion type may change. This causes the codeword of the given code to be set at the checker inputs. The authors consider the finding conditions problem for the undetectable error's absence at the checker inputs when checking calculations by the signal's Boolean correction method using the constant-weight code "2-out-of-5". The checker of this code detects any errors at the inputs, except for those errors that distort the same number of off-bits and on-bits-symmetrical errors. A condition is formulated, following which allows to fix in practice the facts of the symmetrical error's potential formation at the checker inputs and use circuit techniques to parry them. The results obtained by can be generalized to the case of using arbitrary constant-weight code for organizing concurrent error-detection circuit using the signal's Boolean correction method. © 2023 IEEE.

LoRaWAN, a globally utilized LPWAN technology, is predominantly studied and deployed within the European EU868 (868 MHz) and USA US915 (915 MHz) frequency bands, with a vast amount of literature documenting its applications in these regions. However, there is a noticeable gap in research concerning other frequency bands, such as the Australian AU915, which is also utilized in Brazil. This paper aims to explore the characteristics of the AU915 frequency band in Brazil, and how it can affect the performance of an ambience monitoring system application. The study not only focuses on LoRaWAN metrics within the AU915 frequency band but also reveals the practical implications of its unique characteristics. The experiments analyze architectural delays and success rates across various Data Rates (DR) for uplink and downlink messages at different distances, considering the absence of uplink dwell time restrictions. The results demonstrate that, in ambient monitoring systems, different data rates (DRs) significantly influence transmission delays. Additionally, the Uplink Dwell Time restriction eliminates the use of DR0 and DR1 rates, and restricts DR2 in applications using LoRaWAN AU915 in Brazil, directly impacting the success rate of transmissions and, consequently, its network coverage.

In recent power electronics equipment applying GaN semiconductor, etc., the ringing phenomenon, which is the oscillation in the waveform of current due to the short rising and falling time, increases noise and loss. To design magnetic devices in such power electronics equipment, the ringing phenomenon is tried to be simulated using the electromagnetic field analysis taking account of the stray capacitance in this paper. The stray capacitance of the windings is modeled by taking account of the displacement current, and its effect on ringing phenomenon is examined. It is shown that the ringing phenomenon can be represented by taking account of the stray capacitance. © 2023 IEEE.

This study integrated an improved equivalent-input-disturbance (EID) and a repetitive control methods to ensure reference tracking and enhance disturbance-rejection performance for a pedaling rehabilitation robot. A repetitive controller ensures steady-state tracking of a periodic reference input. An EID estimator with a state observer estimates and compensates for the effect of disturbances generated by patients with lower-limb impairment. The stability condition of the closed-loop system is analyzed based on the Lyapunov stability theory. Simulation results show the effectiveness of this method. © 2023 IEEE.

In urban environments, complex transportation demands, including land, air, and maritime transport, are increasingly growing. While significant advancements have been made in land transportation and autonomous driving, research on urban air mobility (UAM) systems is still in its early stages. This paper presents an innovative urban air unmanned aerial vehicle (UAV) framework: AirVista, which is designed and built based on the Artificial systems, Computational experiments, and Parallel execution (ACP) approach, integrated with a multimodal large language model (MLLM) agent. Considering that UAM tasks often require UAVs to possess fine-grained spatial perception and reasoning capabilities, and given that existing MLLMs are somewhat lacking in exploring 3D spaces, this paper further proposes an instruction fine-tuning strategy integrated with 3D spatial knowledge, which has been validated experimentally for its effectiveness. Additionally, to enhance the understanding of the efficiency of MLLM for UAV tasks, this paper delves into prompt fine-tuning templates tailored for UAV task decomposition. Through experimental demonstrations, we showcase that the prompt-tuned MLLM exhibits efficient task decomposition and execution capabilities in handling complex UAV tasks. © 2024 IEEE.

This paper investigates the anomaly-resistant decentralized state estimation(SE) problem for a class of wide-area power systems which are divided into several non-overlapping areas connected through transmission lines. Two classes of measurements(i.e., local measurements and edge measurements) are obtained, respectively, from the individual area and the transmission lines. A decentralized state estimator, whose performance is resistant against measurement with anomalies, is designed based on the minimum error entropy with fiducial points(MEEF) criterion. Specifically, 1) An augmented model, which incorporates the local prediction and local measurement, is developed by resorting to the unscented transformation approach and the statistical linearization approach;2) Using the augmented model, an MEEF-based cost function is designed that reflects the local prediction errors of the state and the measurement;and 3) The local estimate is first obtained by minimizing the MEEF-based cost function through a fixed-point iteration and then updated by using the edge measuring information. Finally, simulation experiments with three scenarios are carried out on the IEEE 14-bus system to illustrate the validity of the proposed anomaly-resistant decentralized SE scheme.
