Control Mechanism For Vertical Farming
(University of Greenwich, 2023-12-18) Alharthi, Abdullah; Robert, Jenner
The purpose of this paper is to examine and assess current control techniques utilized in vertical farming systems with a specific emphasis on enhancing efficiency, sustainability and long-term sustainability. The expansion of vertical farming has been spurred by recent technological breakthroughs and growing worries about food security. This has created a need for strong control systems to assure the best possible plant growth and efficient use of resources. This study aims to investigate the effectiveness of various control systems in vertical farming, including both manual techniques and sophisticated model-based approaches, by building upon current literature and research in the field. The research evaluates the effects of different control approaches on agricultural yields and long-term sustainability by employing a blend of experimental design and engineering design procedures. In order to maximize plant growth and resource utilization, the project makes use of hydroponics and Internet of Things (IoT) technology. By supplying a nutrient-rich solution straight to the roots of the plants, the hydroponics system ensures effective nutrient uptake and does away with the need for soil. The system will be equipped with IoT sensors to track multiple parameters such as supply of nutrient solution and water levels in the system. In order to maximize nutrient solution replenishment and guarantee ideal plant growth conditions, this data will be gathered and examined in real-time. To ensure that every plant receives the same amount of sunlight throughout the day, the system will also include a rotating mechanism. This strategy will reduce the requirement for artificial lighting while optimizing photosynthetic efficiency.

Towards a Hardware-based Solution for Mitigating USB Security Threats in Enterprise Environments
(University of the West of England, 2024) Alharthi, Abdullah; Johnson, Ian
This paper provides a comprehensive analysis of current USB security threats and evaluates the effectiveness and limitations of existing defensive measures. It proposes an innovative solution to bolster enterprise environment security while maintaining USB port functionality. The key component is a smart hub acting as an intermediary between host devices and USB peripherals. This hub enables administrators to selectively authorise usage permissions, ensuring that any connected device to the hub is legitimate. This solution mitigates the vulnerabilities of USB devices, frequently abused for spreading malware and unauthorised data access. The smart hub reduces USB-based attack risks and insider threats by employing effective authentication mechanisms and a strong whitelist management system. This research follows a structured approach, starting with a comprehensive literature review and a detailed evaluation of current security practices, to identify the vulnerabilities the smart hub is intended to address. We proposed the smart hub to integrate seamlessly into organisations, balancing robust security protocols and operational effectiveness. This research contributes significant knowledge to cyber security by offering a solution that allows organisations to securely use USB connections while protecting vital data and systems.
