Der volle Inhalt der QuelleThe main focus of this thesis is on modeling, performance evaluation and system-level optimization of next-generation cellular networks empowered by Unmanned Aerial Vehicles (UAVs) by using Machine Learning (ML). In addition, the emerging technology of Integrated Sensing and Communication is investigated for application to future UAV wireless networks. In particular, relying on Reinforcement Learning (RL) technique for controlling UAV actions, this thesis develops a set of new ML frameworks for incorporating important performance metrics in to the RL agent, such as the communication system throughput and localization error, which can be used for system-level analysis and optimization. More specifically, a new learning-based algorithms proposed to maximize the system throughput by utilizing a prior knowledge of users likelihood of presence in a grid. A Federated Learning (FL) framework introduced to find an optimal path planning through training an agent with RL algorithm in different environment settings to achieve generalization and faster convergence. The performance of UAV equipped with Dual-Functional Radar Communication (DFRC) is investigated and the potential benefits of DFRC systems are shown by jointly optimizing communication system throughput and localization error

Der volle Inhalt der QuelleThe subject of Unmanned Aerial Vehicles (UAVs) has become a promising study field in bothresearch and industry. Due to their autonomy and efficiency in flight, UAVs are considerablyused in various applications for different tasks. Actually, the autonomy of the UAVis a challenging issue that can impact both its performance and safety during the mission.During the flight, the autonomous UAVs are required to investigate the area and determineefficiently their trajectory by preserving their resources (energy related to both altitude andpath length) and satisfying some constraints (obstacles and axe rotations). This problem isdefined as the UAV path planning problem that requires efficient algorithms to be solved,often Artificial Intelligence algorithms. In this thesis, we present two novel approachesfor solving the UAV path planning problem. The first approach is an improved algorithmbased on African Vultures Optimization Algorithm (AVOA), called CCO-AVOA algorithms,which integrates the Chaotic map, Cauchy mutation, and Elite Opposition-based learningstrategies. These three strategies improve the performance of the original AVOA algorithmin terms of the diversity of solutions and the exploration/exploitation search balance. Asecond approach is a hybrid-based approach, called CAOSA, based on the hybridization ofChaotic Aquila Optimization with Simulated Annealing algorithms. The introduction of thechaotic map enhances the diversity of the Aquila Optimization (AO), while the SimulatedAnnealing (SA) algorithm is applied as a local search algorithm to improve the exploitationsearch of the traditional AO algorithm. Finally, the autonomy and efficiency of the UAVare tackled in another important application, which is the UAV placement problem. Theissue of the UAV placement relays on finding the optimal UAV placement that satisfies boththe network coverage and connectivity while considering the UAV's limitation from energyand load. In this context, we proposed an efficient hybrid called IMRFO-TS, based on thecombination of Improved Manta Ray Foraging Optimization, which integrates a tangentialcontrol strategy and Tabu Search algorithms
Liu, Yunsong. „Characterizing methane (CH4) and carbon dioxide (CO2) emissions through mobile platforms from local to national scale“. Electronic Thesis or Diss., université Paris-Saclay, 2022. http://www.theses.fr/2022UPASJ021.
Der volle Inhalt der QuelleMethane and carbon dioxide are the most abundant human-induced greenhouse gases (GHG) in the atmosphere. Their increasing atmospheric concentration is the main driver of climate change. Therefore, it is critical to monitor the evolution of their sources and sinks. Accurate characterization and quantification of their territorial emissions from different sectors are required in order to determine and manage efficient mitigation actions and policies. The main goal of this Ph.D. is to improve the characterization of CH4 and CO2 sectoral emissions from local to national scale through the development of mobile observation strategies including platforms such as car, drone and aircraft.This study consists of three parts. The first part aims at verifying a national CH4 inventory with a replicable method. I focus on surveying and quantifying significant methane emitters that represent 28% of national (Cyprus) methane emissions. These are essentially landfills and cattle farm areas. The approach is based on car-based mobile measurements and Gaussian plume dispersion modelling. The calculated methane emissions from landfills and enteric fermentation of cattle were about 160% and 40% larger, respectively, than the bottom-up sectoral estimates used in the national inventory. These mobile surveys show that an ensemble of in situ measurements targeting representative methane emission hotspots with consistent temporal and spatial coverage can largely improve national bottom-up emission inventories.The second part focuses on methods to quantify CH4 emissions for the oil and gas industry. It compares ten state-of-the-art commercial methane quantification systems through a series of controlled release experiments at an inert compressor station. The controlled releases covered a range of situations including various leak rates and wind conditions. The results indicated that ‘source-level' systems (close to single leak) generally underestimate emissions, while ‘site-level' systems (integrating emissions for the site) relying on atmospheric dispersion slightly overestimate emission rates. The analysis of this part highlights that unmanned aerial vehicles (UAV) have the potential to bridge the gap between ground-based and airborne observations but are strongly wind sensitive.The last part focused on the development of UAV GHG measurements. I have developed and validated a novel portable UAV-CO2 sensor system that is lightweight but remains sufficiently precise. Through a careful sensor characterization, correction and calibration procedure, we reach an in-flight precision of ± 2 ppm (1σ) at 1 Hz and ± 1 ppm (1σ) at 1 min. This system is relatively inexpensive and easy to reproduce, and has the potential to perform a wide range of field applications, such as urban and point source emissions monitoring.In short, this Ph.D. makes a step forward for future reconciliation of GHG emission estimates based on various observation systems and different approaches, and seeks methods that are easily duplicated and applicable to other regions and emission sectors. While mobile approaches presented here clearly represent important monitoring options, significant challenges remain in current capacity to estimate routinely anthropogenic GHG emission trajectories with sufficient precision and at large scale

Der volle Inhalt der QuelleNowadays, applications of autonomous quadrotors are increasing rapidly. Surveillance and security of industrial sites, geographical zones for agriculture for example are some popular applications of Unmanned Aerial Vehicles (UAVs). Nowadays, researchers and scientists focus on the deployment of multi-UAVs for the inspection and the surveillance of large areas. The objective of this thesis is to design algorithms and techniques to perform a real-time distributed/decentralized multi-UAVs flight formation control, from a system of systems perspective. Firstly, we reviewed recent works of the literature about flight formation control and the control of quadrotors. We presented a brief introduction about systems of systems, their definition and characteristics. Then, we introduced the flight formation control with its most used structures in the literature, some existing works dealing with flocking. Finally, we presented the most used modeling methodologies for quadrotors and some control approaches that are used to stabilize quadrotors. Secondly, we used the behavioral-based control structure to achieve a multiple UAV flocking. We conceived a behavior intending to address the control design towards a successful achievement of the flocking task without fragmentation. The proposed behavior treats the flocking problem from a global perspective, that is, we included a tendency of separated UAVs to form a flock.System of systems challenges motivated us to look for flocking and consensus algorithms introduced in the literature that could be helpful to answer to these challenges. This led us to propose four flocking control laws aiming at being compatible with the nonlinear model of quadrotors and at being implemented on experimental platforms. The control laws were run aboard each quadrotor in the flock. By running the control law, each quadrotor interacts with its neighbors to ensure a collision-free flocking. Finally, we validated our proposed control laws by simulations and real-time experiments. For the simulation, we used a PC-based simulator of flock of multiple quadrotors which was developed at Heudiasyc laboratory. For experiments, we implemented our control laws on ArDrone2 quadrotors evolved in an indoor environment equipped with an Optitrack motion capture system
