In recent years, a growing demand for alternative energy sources, including solar energy, has been observed. This article presents methodology assessing the potential of buildings using images from Unmanned Aerial Vehicles (UAVs) and point clouds airborne LIDAR. The proposed method includes following stages: DSM generation, extraction building footprints, determination roof parameters, map removing areas that are not suitable installation systems, calculation power per each building, conversion irradiance into mapping generation. paper describes also Detecting Photovoltaic Panels algorithm with use deep learning techniques. enabled efficiency photovoltaic panels comparing results maps buildings, as well identifying require optimization. analysis, which had conducted in test village on campus university, confirmed usefulness above methods. analysis provides UAV image data enable generation higher accuracy (MAE = 8.5 MWh) than LIDAR 10.5 MWh).

Swimming pools, a globally popular recreational activity, necessitate effective disinfection to mitigate potential health risks arising from water contamination. Trichloroisocyanuric acid (TCCA), prominent disinfectant, is pivotal in pool treatment. This paper investigates the impact of trichloroisocyanuric concentration on electrical properties swimming water. Water samples were collected covered El Jadida, Morocco, disinfected with varying concentrations acid, and analyzed using impedance measurements. The pool's treatment system, including pre-filters pressure filters multi-layer beds, was described. Thorough examinations bromate, chlorate, chlorite conducted. obtained quality parameters met standard limits, indicating favorable conditions. complex conductivity different explored. An equivalent circuit model successfully described relaxation behavior, emphasizing intricate relationship between physicochemical Changes times DC observed increasing concentrations, providing valuable insights for optimization. nuanced understanding dynamics variations contributes optimizing maintenance strategies, ensuring safe enjoyable environment.

Irrigation is crucial for agricultural production in dry regions. However, water salinity a risk the soil–plant combination and longevity of materials that make up irrigation system. Drip using direct intermittent photovoltaic pumping can be key optimizing with saline water. This article compares two pump models to understand which has greatest capacity reduce risks irrigated agriculture, aiming system more sustainable through efficient irrigation, without need highly expensive corrective cleaning measures. The ideal was evaluated motor pump’s electrical hydraulic parameters water’s quality applied by irrigation. results indicate diaphragm sensitive disturbances management when compared centrifugal pump; however, it stands out following areas: efficient, is, operates hours day connection panels; delivers better distribution uniformity both continuous pulsed application; makes drip resistant clogging.
