This paper presents a control scheme for aerial manipulators which allows to solve different motion problems: end-effector position control, trajectory tracking and path-following control. The has two cascaded controllers: i) the first controller is minimum norm based on numerical methods, it solves three problems just by modifying references. Also, since manipulator robot redundant system, i.e., extra degrees of freedom accomplish task, possible set other objectives in hierarchical order....

Recent technological advances have brought increased attention to aerial robotic manipulators (ARMs), particularly in applications involving physical interactions. However, translating control algorithms into real-world for may prove challenging, given the potential accidents and time-consuming nature of experiments; furthermore, acquisition could impose a substantial financial burden on universities, research centers, companies. Therefore, this work addresses these issues by developing an...

In a first stage cancer promotes an intense process of vascularization at the affected area increasing blood flow and modifying local temperature body. Using thermal camera, infrared radiation emitted by human body can be captured then used in measuring temperature, turning results into image. Moreover, thermography detect suspicious regions patients any age, even cases dense breasts, where detection abnormality cannot accomplished others exams. A fundamental step use images is development...

Breast cancer is one of the leading causes for high mortality rates among young women, in developing countries. In Latin American this an important health problem, instance Brazil and Ecuador cause women around 35 years old. Currently mammography used as gold standard screening breast cancer. However, mammograms are not recommended due low contrast it presents on dense breasts alternative techniques must be considered purpose. The World Health Organization states that programs more efficient...

Breast cancer is major cause of the high mortality rates among young women in developing countries. In Latin America, it a great health problem, as well. For example Brazil and Ecuador, this leading around 35 years old. Early detection important to improve chance cure. Thermal imaging has ability show regions where there any potential by indicating areas body an abnormal temperature variation. Moreover, thermography can detect suspicious patients age, even cases dense breasts, abnormality...
