- Autonomous Precision Landing for Commercial UAV: A Review
This paper reviews a various methods exploring the topic of unmanned aerial vehicles (UAV) autonomous precision landing, covering two types of commercial UAVs, multi-rotor and fixed-wing UAVs. Four general methods gain the most eminence for the autonomous precision landing, which generally known as visual processing landing, satellite navigations landing, ground station navigation landing, and arrestor recovery landing. The assessment of the landing accuracies of each method are assessed and compared, if the results are being made available in the reviewed research articles. We also discussed the recent breakthroughs in sensors, processor, and flight technologies that can further improve the accuracy of UAV autonomous precision landing.

- REMOTE DESKTOP POWER MANAGEMENT SYSTEM USING SINGLE-BOARD COMPUTER
In this paper, remote desktop power management system is proposed for remote power management of multiple desktop computers. This system will enable desktop computer to be restarted, switch on or off in the event of computer freeze or based on user input by controlling the power to the desktop computer. The system has the ability to monitor the environment parameters such as the temperature, humidity, and air quality surrounding the desktop computer. This remote desktop power management system can be accessed primarily using website interface. This system will save time and cost as less on-site maintenance and monitoring is needed.

- Investigations of Lift and Drag Performances on Neo-Ptero Micro UAV Models
This paper presents the investigation and improvement of lift and drag characteristics of Neo-Ptero micro-UAV models based on the virtual wind tunnel method. Despite its successful development and flight stability, the lift and drag coefficients characteristics of the current Mark 1 Neo-Ptero remain unknown. To improve the Mark 1 Neo-Ptero performances, Mark 2 Neo-Ptero model has given a new unsymmetrical airfoil wing configuration. The computational aerodynamic analysis was executed and focused on certain lift and drag coefficient characteristics. Lift coefficient results showed that Mark 2 improved in overall lift characteristics such as zero-lift angle, maximum lift magnitude and stall angle magnitude. Conversely, Mark 2 model suffered a slightly higher drag coefficient magnitude and more significant drag increment percentage than Mark 1. However, the trade-off between superior lift magnitude and minor drag generation induced by Mark 2 boosts the model’s aerodynamic efficiency performances but is only limited at early angle stages.
