As global demand for renewable energy continues to rise and available land resources become increasingly scarce, floating photovoltaic (FPV) systems have emerged as a cost-effective solution to meet energy needs while minimizing environmental impacts. In 2023, the global installed capacity of FPV reached 5.9 GW and is projected to grow to 10 GW by 2030. This review systematically examines the current status and historical development of floating solar technology, focusing on key challenges and solutions in structural design and material selection. It also explores methods to enhance FPV efficiency, including optimal tilt angles, cooling systems, bifacial modules, and tracking systems, while addressing the economic feasibility of FPV. Furthermore, a simulated 2 MW FPV system based on meteorological data from Suwon, South Korea, is analyzed. The system demonstrates a high-performance ratio of 90.5% and a maximum system production output of 1835 MWh when the tilt angle is optimized between 32° and 34° and the azimuth angle is set to 0°. © 2025 Wiley-VCH GmbH.

Building-integrated photovoltaics (BIPVs) provide a dual-purpose solution, functioning as both energy-generating systems and integral building materials. BIPV adoption has been limited due to a lack of color integration, preventing the panels from being used in building designs. However, efforts to incorporate color into the BIPV layers have been made, but they often reduce panel efficiency. BIPV implementation faces several challenges that hinder widespread adoption, such as fire safety concerns and the integration of color aesthetics and light-emitting diode technology. This article explores these challenges and recent advancements that enhance the aesthetic versatility and efficiency of BIPV systems, including the use of quantum dots, Bragg reflectors, and silver-alloyed copper indium gallium selenide cells. The study also highlights critical considerations for optimizing BIPV systems, such as energy performance and fire safety. PVsyst 7.2 simulation results for a 10 kW BIPV system installed in South Korea demonstrate effective strategies for mitigating efficiency losses through investigating the orientation of angles. Results showcase a high-performance ratio of 0.891, a high production of 14 147 kWh year−1 at a tilt angle of 30° while facing south, and a peak energy of almost 1450 kWh injected into the grid under varying conditions. © 2025 Wiley-VCH GmbH.

Journal of Microwaves, Optoelectronics and Electromagnetic Applications 2025年第2期24卷

作者： de Sousa, Bruno Matias Duarte, José Garibaldi da Silva Neto, Valdemir Praxedes Graduate Program in Electrical and Computer Engineering Federal University of Rio Grande do Norte RN Natal Brazil Department of Communication Engineering Federal University of Rio Grande do Norte RN Natal Brazil

This study proposes a low-cost microwave sensor for the monitoring of water quality contamination in irrigation systems. The sensor was employed for monitoring the concentration of specific compounds in mixtures of glucose and water, in order to prevent the accumulation of unwanted sugars in large plantations. The proposed sensor is an adaptation of a complementary split ring resonator (CSRR) fabricated on an FR4 substrate. A capillary tube constructed from polypropylene is inserted into the region of the CSRR microwave sensor exhibiting the maximum density surface current, wherein the liquid under test (LUT) is contained. The sensor was designed to operate at a resonance frequency of 2.45 GHz in the absence of a load. The maximum displacement observed at the resonance frequency is 275 MHz, with a normalization sensitivity of 0.844%. The simulations and experimental measurements are verified and their results compared, yielding a high level of concordance for the sensor’s intended purpose. The discrepancy between the measured permittivity values and the reference values of the samples under analysis is less than 5%. The proposed sensor is an effective solution for characterizing liquids, particularly mixtures of water and glucose, when compared to other sensors available for this application. © 2025 SBMO/SBMag.

Correntropy-Based Data Selective Adaptive Filtering

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.

Recently, various analytical models have been proposed to analyze the performance of traditional EPONs. However, these analytical models are not readily applicable to analyze the performance of WDM EPON systems since they are aimed specifically at a single-channel EPON environment. Accordingly, this paper constructs an analytical framework comprising an M/M/1 queuing model and a recursive formulation to analyze the performance of the offline scheduling polling policy in a multi-channel WDM EPON network with differentiated services. The analytical results derived using this model for the mean queuing delay and mean queue length are found to be in good agreement with those obtained from computer simulations.

Recently, the research on daily health monitoring using a wearable sensor has been continually evolving. In the future, when this system is actually implemented, a vast amount of data transmission will be conducted from multiple sensors to the cloud server. A system capable of transmitting, storing, processing, and visualizing massive volumes of data is necessary for health monitoring. This research aims to develop a health monitoring system that can accommodate a high amount of data with high performance. The proposed techniques include numerous modifications to system architecture and technology. In the system architecture, a multi-database is proposed to enhance the reliability of the system. As an enhancement to the technology aspect, a time series database and MQTT server are proposed. As the result, the proposed system achieves significantly better performance in terms of throughput, database-writing speed, and database-reading speed compared to the existing system. © 2022 IEEE.

This paper develops a movement-analysis ambulatory monitor, designated as ActionView, which can be used in an elderly homecare system to analyze the body movements of elderly individuals whilst in their homes. ActionView monitor is equipped with a kinematic sensor to effectively detect the changes in the upper-body orientation and vertical acceleration of the individual. Furthermore, a remote backend server receives the detected signal from the kinematic sensor via a Wireless Sensor Network (WSN) and then identifies the corresponding body motion. The experimental results show that ActionView has a classification accuracy of approximately 90% when applied to the recognition of everyday elderly actions such as standing up, sitting down, walking, and so forth. ©2009 IEEE.

Long-reach optical access technologies have emerged as a promising solution for combining access and metro backhaul networks in a cost-effective manner. This study develops a Slotted PON (SPON) architecture based upon an AWG for long-reach optical access networks. The AWG enables the SPON to achieve wavelength spatial-reuse and to provide an internetworking capability amongst ONUs located within different local access networks. In addition, a Slotted MAC (SMAC) protocol is proposed to arbitrate the access of the individual ONUs over the DWDM layer. The simulation results show that the SPON architecture integrated with SMAC protocol enhances the bandwidth utilization within the network, and therefore achieve a significant reduction in the average packet delay. © 2009 IEEE.
