This work focuses on understanding and identifying the drag forces applied to a rotary-wing Micro Aerial Vehicle (MAV). We propose a lumped drag model that concisely describes the aerodynamical forces the MAV is subject to, with a minimal set of parameters. We only rely on commonly available sensor information onboard a MAV, such as accelerometer data, pose estimate, and throttle commands, which makes our method generally applicable. The identification uses an offline gradient-based method on flight data collected over specially designed trajectories. The identified model allows us to predict the aerodynamical forces experienced by the aircraft due to its own motion in real-time and, therefore, will be useful to distinguish them from external perturbations, such as wind or physical contact with the environment. The results show that we are able to identify the drag coefficients of a rotary-wing MAV through onboard flight data and observe the close correlation between the motion of the MAV, the measured external forces, and the predicted drag forces.

Reducing the power consumption of computing devices remains a challenge for the data center industry. In 2022, it represents approximately 2% of global electricity consumption and 1% of global greenhouse gas emissions. In addition, data centers must integrate the 5G and B5G challenges into their strategies, by increasing the computing resources available to face higher-quality service constraints. Indeed, 5G and B5G future networks are increasingly software-oriented and therefore, rely heavily on cloud computing to process large amounts of data from multiple sources in real-time. Several research works on energy management have been proposed to ensure a reduction of the energy consumed by the various components of a data center (e.g., software, computing devices, or cooling systems). However, to optimize the energy consumption of computing devices (e.g., virtual machines/container operations), it is essential to have an accurate model for predicting power consumption. Thus, we propose in this study a new sensor predictive model to predict the dynamic power consumption of cloud computing devices with high accuracy. Our proposal takes advantage of the various sensors that are now embedded in physical machines, or more generally in cloud server machines, as well as Performance Monitoring Counters to implement a Machine Learning power prediction model. The performance evaluation results confirm that our power consumption prediction models outperform previous literature models in terms of accuracy. Indeed, our best model achieves a R2 score of 93.6% which is higher than the compared baseline model by 21.1%.

This paper explores the application of centralised and distributed Gaussian process algorithms to real-time target tracking and compares their performance. By embedding the algorithms into the Stone Soup, the focus is on the innovative implementation of Gaussian process methods with learning hyperparameters and implementation with a factorised variance of the Gaussian kernel. The performance of the methods with different kernels was evaluated, not only with the Gaussian kernel. Extensive experiments with various kernel configurations demonstrate their importance in enhancing prediction accuracy and efficiency, especially in real-time tracking. The case studies with manoeuvring targets show significant advancements in tracking capabilities, particularly in wireless sensor networks, using optimised Gaussian process methods. This work advances Stone Soup's capabilities and lays the groundwork for future investigations into adaptive Gaussian Process applications in tracking and sensor data analysis.
