Application of zonal pricing in Greece's electricity market
(2009)Greece's electricity market is divided in two zones, North and South, due to a generation-consumption system configuration that creates a significant transmission bottleneck from North to South. Clearly, a zonal pricing ... -
An assessment of a unmanned aerial vehicle-based broadcast scenario assuming random terrestrial user locations
(2021)With the advent of the new decade, unmanned aerial vehicles (UAVs) will increasingly play an active role mainly as broadband transmission relays for broadcast applications. In the present study, we consider a feasible ... -
Backbone formation in military multi-layer ad hoc networks using complex network concepts
(2016)Modern battlefields are characterized by increasing deployment of ad hoc communications among allied entities. These networks can be seen as a complex multi-layer ad hoc network, where each layer may be an independently ... -
Creation of a remote sensing unmanned aerial system (UAS) for precision agriculture and related mapping applications
(2013)Our goal is to create a fully autonomous airborne remote sensing platform, for the production of various vegetation indices to determine growth, development, yield crop and provide considerable information in real time and ... -
A Deep Reinforcement Learning Motion Control Strategy of a Multi-rotor UAV for Payload Transportation with Minimum Swing
(2022)This paper addresses the problem of controlling a multirotor UAV with a cable-suspended load. In order to ensure the safe transportation of the load, the swinging motion, induced by the strongly coupled dynamics, has to ... -
Energy-Efficient UAV-Relaying 5G/6G Spectrum Sharing Networks: Interference Coordination with Power Management and Trajectory Design
(2022)As massive ground users access wireless networks with limited available spectrum, coexisting users that share the same spectrum band severely interfere with each other. Moreover, communication pairs without direct communication ... -
Exploring the Random Location Problem Inside a Truncated Conic Shape: Application in UAV Communications
(2022)More often than not, transmitters (Txs) in wireless networks operate using directional radiation patterns where the main radiation lobe creates a three-dimensional conic-shaped volume. In this context, any receiver (Rx) ... -
A Fault-Tolerant Control Scheme for Fixed-Wing UAVs with Flight Envelope Awareness
(2021)In this work a vertically integrated fault-tolerant control scheme for fixed-wing Unmanned Aerial Vehicles (UAVs) is presented. At its core, an online approximate Trim Flight Envelope generator yields the motion constraints ... -
A Fault-Tolerant Control Scheme for Fixed-Wing UAVs with Flight Envelope Integration
(2020)Fault-tolerant control is currently the most important step towards increased autonomy for Unmanned Aerial Vehicles (UAVs). In this work, we consider actuator and airframe faults in fixed-wing UAVs and show that an online ... -
Formation Control and Target Interception for Multiple Multi-rotor Aerial Vehicles
(2020)In this paper, we present a distance-based formation control strategy for multiple multi-rotor aerial vehicles participating in a target interception mission. The target moves arbitrarily, following a smooth 3D trajectory, ... -
Indoor Visual Exploration with Multi-Rotor Aerial Robotic Vehicles
(2022)In this work, we develop a reactive algorithm for autonomous exploration of indoor, unknown environments for multiple autonomous multi-rotor robots. The novelty of our approach rests on a two-level control architecture ... -
MONITORING CASTOR BEANS MATURITY VIA REMOTE SENSING
(2022)Castor is a crop with an evergreen habit so artificial induced ripening is an essential precondition for mechanical harvesting of new dwarf annual hybrids. Plants water content impose a determinant effect both on preharvest ... -
Performance and Channel Modeling Optimization for Hovering UAV-Assisted FSO Links
(2022)Unmanned Aerial Vehicle (UAV)-assisted free-space optical (FSO) communication has become a promising solution in both civil and military applications. Nevertheless, hovering UAV-assisted FSO links suffer from several losses ... -
Pricing based MEC resource allocation for 5g heterogeneous network access
(2019)Multi-access Edge Computing (MEC) is expected to play an important role in next generation networks, as it is able to provide resources accessible through multiple wireless technologies located close to the network edge. ... -
A Survey on Fault Diagnosis Methods for UAVs
(2021)The continuous evolution of modern technology has led to the creation of increasingly complex and advanced systems. The growing demands for more reliable performance on such systems as the Unmanned Aerial Vehicles (UAVs), ... -
A Visual Servoing Strategy for Coastline Tracking using an Unmanned Aerial Vehicle
