Enhanced Parallel Generation of Tree Structures for the Recognition of 3D Images
(Springer, 2019)
Segmentations of a digital object based on a connectivity criterion at n-xel or sub-n-xel level are useful tools in image topological analysis and recognition. Working with cell complex analogous of digital objects, an ...

Model Predictive Control for Spacecraft Rendezvous in Elliptical Orbits with On/Off Thrusters
(Elsevier, 2015)
In previous works, the authors have developed a trajectory planning algorithm for spacecraft rendezvous which computed optimal Pulse-Width Modulated (PWM) control signals, for circular and eccentric Keplerian orbits. The ...

Use of Aerial Thermal Imaging to Assess Water Status Variability in Hedgerow Olive Orchards
(2016)
Characterization of the spatial variability in tree water status is a prerequisite to conduct precise irrigation management within an orchard. This study assessed the suitability of a crop water stress index (CWSI) derived ...

Explicit boundary control of a reaction-diffusion equation on a disk
(Elsevier, 2014)
This paper introduces an explicit full-state boundary feedback law that stabilizes an unstable linear constant-coefficient reaction-diffusion equation on a disk. The backstepping method is used to design the control law. ...

Trajectory Planning for Spacecraft Rendezvous in Elliptical Orbits with On / Off Thrusters
(Elsevier, 2014)
In a previous work, the authors developed a trajectory planning algorithm for spacecraft rendezvous which computed optimal Pulse-Width Modulated (PWM) control signals, assuming that the target was moving in a circular ...

Probabilistic Analysis of Aircraft Fuel Consumption Using Ensemble Weather Forecasts
(International Conference on Research in Air Transportation (ICRAT), 2016-06-20)
The effects of wind uncertainty on aircraft fuel consumption are analyzed using a probabilistic trajectory predictor. The case of cruise flight subject to an average constant wind is considered. The average wind is ...

Automatic weed control system for processing tomatoes
(2010)
This study describes a fully automatic system developed at UC Davis for intra-row mechanical weed control for processing tomatoes in California. We developed a novel weed control system using a real-time kinematics (RTK) ...

Backstepping-Based Exponential Stabilization of Timoshenko Beam with Prescribed Decay Rate
(Elsevier, 2022)
In this paper, we present a rapid boundary stabilization of a Timoshenko beam with anti-damping and anti-stiffness at the uncontrolled boundary, by using PDE backstepping. We introduce a transformation to map the Timoshenko ...

Cavity losses estimation in CSP applications
(American Institute of Physics, 2018)
Estimations of convection and radiation cavity losses in two common CSP applications have been analyzed; a cavity in a solar tower plant for high temperature (800 K) and in a down facing cavity in a Fresnel configuration ...

Implementation in MATLAB of a Multiplicative Extended Kalman Filter for live estimation of a smart device's attitude
(Elsevier B.V., 2021)
This work introduces the tools used to teach the Kalman Filter (KF) to Aerospace Engineering students in the University of Seville. In particular, an easy-to-set-up application is introduced; based on the Matlab framework ...
