Precision Agriculture aims to apply selective treatments and tasks at localized areas concerning crop fields. Robotized and autonomous tractors, equipped with perception, decision-making and actuation systems, can apply specific treatments as may be required. Correct plant identification through the perception system, including crops and weeds, is...

Machine vision systems are becoming increasingly common onboard agricultural vehicles (autonomous and non-autonomous) for different tasks. This paper provides guidelines for selecting machine-vision systems for optimum performance, considering the adverse conditions on these outdoor environments with high variability on the illumination, irregular...

We provide an alternative methodology for vegetation segmentation in cornfield images. The process includes two main steps, which makes the main contribution of this approach: (a) a low-level segmentation and (b) a class label assignment using Bag of Words (BoW) representation in conjunction with a supervised learning framework. The experimental re...

Autonomous mobile vehicles are becoming commoner in outdoor scenarios for agricultural applications. They must be equipped with a robot navigation system for sensing, mapping, localization, path planning, and obstacle avoidance. In autonomous vehicles, safety becomes a major challenge where unexpected obstacles in the working area must be convenien...

This work develops a new set of severity scores that combine several cranial features in order to quantify sagittal and metopic craniosynostosis. Computed tomography head scans were obtained from 90 children affected with single-suture sagittal synostosis, 40 children with single-suture metopic synostosis, and 60 age-matched nonsynostotic controls....

In this paper a new system, called ohtli-PR, is presented. This system was developed for fuel lattice design optimization in Boiling Water Reactors (BWR) using the Path Relinking and Scatter Search techniques. As input data, the system uses an initial uranium enrichment and gadolinia percentage. At the beginning of the optimization process, the sys...

Single-suture craniosynostosis (SSC) is the pathologic condition of premature fusion of a calvarial suture. Premature fusion produces significant cranial deformities and is associated with an increased risk of cognitive deficits and neurobehavioral impairments. For these reasons, SSC represents an important area of research that requires effective...

A new system, named Ohtli-PR, for the optimization of fuel lattice design in Boiling Water Reactors (BWR), using the heuristic technique called Path Relinking was developed. The system starts with an initial proposal of uranium enrichment and gadolinia concentration. With this information, the system generates a seed fuel lattice, which is used to...
