This paper provides design and task management of the first stage of a project entitled “Fall-Army Worm (FAW) insect killer”. The project has three main stages: design and energy management stage, flying control of drone stage and detecting and killing FAW stage. The goal of this project is to detect and kill; without chemical methods; a harmful FAW insect which is rapidly spreading in Africa and Asia. This paper focuses on design of the first stage of the system, getting maximum power and controlling the energy of the system. A Photo Voltaic system with energy storage devices is proposed to be the source of power. A new algorithm to control the time scheduling of the killing and detection mission is proposed and its effects on the system’s energy and mission period are studied. A comparison between different methods for tracking the maximum power from PV panels is performed to choose the best (less time and high accuracy) method. The results of simulation indicate the effectiveness of the proposed maximum power tracking and task management system.
This paper provides a design, a charging control, and energy management of a movable Photo Voltaic (PV) charging station with an Automatic Battery Replacement (ABR) system to enable drones for ongoing missions. The paper represents the first stage of a three-staged project titled Fall Armyworm (FAW) insect killer. The other two stages involve the flight control of drones and detecting and killing FAW insects. Without chemical methods, the project aims to eliminate harmful FAW insects that are rapidly spreading in Africa and Asia. The power source is a hybrid PV system with energy storage devices (batteries and supercapacitors). The maximum power from PV panels is tracked using three different online methods (PSO, IC, and P&O), and the best method with the highest accuracy is selected. The experimental and simulation results approved that PSO is the recommended method used in this project among the studied methods because of its high target reach (about 97%) and low steady-state oscillation (maximum 2.15%). An intelligent energy management system is investigated and designed to efficiently utilize solar power with a constant-current constant-voltage charger for LiPo batteries. A new Battery Selection System (BSS) is designed and verified to efficiently utilize the harvested energy and increase the mission time. The BSS targets to manage the selection of the appropriate battery to charge and control its charging rate. The system performance is tested using MATLAB software. Then, an experimental setup for the system is built to validate simulation results. The results of simulations and experiments proved the reliability of BSS in different operating cases with an efficiency higher than 97%.
The study addresses the manners of achieving quality of public parks as urban spaces to fulfill inclusiveness and community participation, in light of the universal design (UD) approach. Thus, the research problem aspect lies in the inadequacy of the urban and architectural elements of Ferial Park for the potential of people who suffer from a decrease in their physical abilities, which led to the non-achievement of inclusiveness and community participation, hence social sustainability within the park. The term "universal design" was coined in the 1950s in the USA by Ronald Mack, who defined it as "the design of environments, products, and services consistent with all human capabilities to the greatest possible extent". Previous studies showed the lack of addressing the UD approach in public parks, thus, the study targets to conduct an assessment of the Ferial Park's elements at Aswan city, Egypt, to evaluate the extent of its compliance with the UD concept, then determining the weaknesses and eliminating them. The A Methodology for Assessing the Quality of Public Gardens Mai Eid, et al, P 1-202 study relied on the descriptive analytical approach to analyze the park elements and compare them with the UD standards to determine the extent to which the park features met the demands of all members of society fairly. The researchers' observations were done by the prepared checklist of this study. The study results revealed that the park's elements achieve the UD standards significantly by 10% and non-achieve those standards by 57%, which confirms that the park does not achieve inclusiveness. Consequently, there is a need to raise the efficiency of park elements. The study concluded some recommendations such as providing proper corridors, ramps and selecting ground materials that help ease of movement.
