They have negative impact on the system’s output characteristics which results in reducing operating reliability and power loss. In order to optimize the system harvested generation, this research suggests a new dynamic reconfiguration of PV-TEG generating unit using the most recent blood-sucking leach optimizer (BSLO). The problem is presented as restricted optimization problem with the purpose of improving the generated power from PV-TEG unit. Many benefits come with the suggested methodology including strong local solution avoidance ability, rapid convergence speed, and outstanding exploration/exploitation balance. The symmetric 6 × 6 and asymmetric 6 × 10 arrays under ten PSCs including uneven column and row, long and short wide, long and short narrows, outer, diagonal, random, and center patterns are the two case studies that are investigated. The suggested BSLO is validated through conducting comparison to reported approaches and other programed Puma optimization algorithm (POA), artificial gorilla troops optimizer (GTO), and Beluga whale optimization (BWO). The suggested BSLO yields better generation boost of 27.04% for symmetric 6 × 6 array compared to the POA that obtained 23.86% during short wide shade pattern. However, the best enhancement that the suggested BSLO achieved for asymmetric 6 × 10 array during short wide pattern is 15.29%.

The quadrature hybrid with the BCS structure provides 90-degree phase difference signals to the circular radiator, which is uniformly distributed across a short-distance aperture through the spherical lens, resulting in a narrowly radiating beam. The primary challenges addressed by this design include achieving narrow beamwidth (HPBW < 8°), low sidelobe level (SLL < 38 dBc at angles > 60°), and compact form factor (length < 20λ) simultaneously with cost-effective manufacturing. The most notable feature of the proposed antenna is its short length (14.5λ), made possible by using an inexpensive single-medium spherical lens, compared to the existing RLM antennas that are much longer.

While most modern sensors infer SWC by measuring the soil’s dielectric permittivity, the relationship between these two properties is not universal and is significantly influenced by site-specific factors such as soil texture, composition, and salinity. Without appropriate calibration, this leads to substantial errors in SWC estimation, including inaccurate assessments of water availability, flawed data for hydrological models, and misguided irrigation decisions. This manuscript addresses this challenge by systematically outlining the necessity of soil-specific calibration and providing a detailed explanation of various calibration methodologies for different soil types. It describes the dependencies and discrepancies in using dielectric properties for SWC measurement and reviews the models that overcome these limitations, from empirical approaches to physically-based dielectric mixing models. Furthermore, the work explores future directions, highlighting the potential of emerging technologies like hyperspectral imaging to complement traditional dielectric sensing techniques.

These analyses contribute to the development of effective financial techniques. This paper presents a techno-economic design for an HMG that combines AC and DC elements such as diesel generators (DG), photovoltaic (PV), wind turbines (WT), batteries (BAT), and power converters (Conv) to satisfy the power demand of a rural health clinic with a daily load of 110 kWh, situated in the desert area of Nubian in Aswan, Egypt. The optimization of HMG is performed through HOMER Pro based on hourly wind speed, solar irradiance, and clinic load data to evaluate the cost of electricity, carbon emissions, loss of power supply probability, and renewable fraction. The results are compared across four different HMG combinations: PV/WT/BAT/Conv, DG/PV/BAT/Conv, DG/PV/WT/BAT/Conv, and WT/DG. The simulation outcomes indicate that the system incorporating the WT/DG/PV/BAT/Conv provides the most efficient techno-economic solution for meeting the clinic’s power demand. The optimal configuration includes 4 kW of DG, 10 kW of WT, 9 kW of PV, 36 batteries, and 16 kW of power converters. This system achieves the lowest 51.76 k$ of net present cost and 0.107 $/kWh of cost of electricity, 3051 kg/year of CO<sub>2</sub> emissions, and a significant renewable contribution of 90.7 %.
