Modeling of an unmanned hybrid aerial vehicle
2014 IEEE Conference on Control Applications (CCA), 2014 In this paper, the mathematical modeling of ahybrid aerial vehicle is presented. This vehicle is a combinationof a fixed-wing aircraft and a multirotor helicopter. Thisvehicle is thus capable of vertical take off and landing (VTOL)and of cruising forward flight.

Advanced Intelligent Systems, EarlyView.This study assesses the suitability and performance of single‐image super‐resolution methods when applied directly, and without any fine‐tuning, to multispectral images of maize and sunflower crops. It evaluates not only super‐resolution performance, but also the preservation of spectral integrity and vegetation‐index reliability. Multispectral imagery

A guidance system for unmanned air vehicles
2013 21st Signal Processing and Communications Applications Conference (SIU), 2013 Unmanned air vehicle system is composed of control station, payload, air vehicle, navigation and communication subsystems. Among these, navigation and guidance are most important subsystems. By using the lateral and vertical navigation guidance systems, the planned flight transition of the UAV can be realized from departure waypoint to the target.
