Fixed-wing Miniature Air Vehicle (MAV) is not only coupled with longitudinal motion, but also more susceptible to wind disturbance due its lighter weight, which brings challenges altitude and airspeed controller design. Therefore, in this paper, an improved control strategy based on energy state, proposed address the above-mentioned issues. The utilizes Linear Extended State Observer (LESO) obs...

Introducción: Las malformaciones arteriovenosas cerebrales (MAV) son un conjunto anormal de arterias y venas dilatadas del cerebro caracterizadas por la pérdida organización vascular con una derivación arteriovenosa anormal. La probabilidad ruptura MAV es baja, pudiendo causar déficit hasta en el 45% los pacientes. epilepsia puede asociarse siendo raro estado epiléptico. evolución a epil...

The use of a multi-camera system enables a robot to obtain a surround view, and thus, maximize its perceptual awareness of its environment. An accurate calibration is a necessary prerequisite if vision-based simultaneous localization and mapping (vSLAM) is expected to provide reliable pose estimates for a micro aerial vehicle (MAV) with a multi-camera system. On our MAV, we set up each camera p...

Micro-aerial vehicle (MAV) swarms are a new class of mobile sensor networks with many applications including search and rescue, urban surveillance, radiation monitoring, etc. These sensing applications require autonomously deploying a high number of low-cost, lowcomplexity MAV sensor nodes at suitable locations in hazardous environments. We propose a collaborative algorithm for resource-constra...

In this paper, a path planner is proposed for a fixed wing micro air vehicle (MAV), in the framework of fuzzy quadtrees. It is shown that a fuzzy version of the quadtree planner is apt for micro air vehicle applications with severe space, power and budgetary constraints. The algorithm can significantly reduce both space and time complexity and still yield an optimal and safe path for the vehicl...

Severe adenovirus infections in transplant recipients undergoing immunosuppressive therapy are of increasing concern. Controversy exists on the contribution of antiviral therapy and the host immune response to recovery from these infections. Here, we established a systemic mouse adenovirus type 1 (MAV-1) infection in cyclophosphamide (CyP)-treated BALB/c mice. CyP was administered at 100 mg per...

In this paper, we propose a monocular vision system for approach and landing using a low-cost micro aerial vehicle (MAV). The system enables an off-the-shelf Parrot AR.Drone 2.0 quadrotor MAV to autonomously detect a landpad, approach it, and land on it. Particularly, we exploit geometric properties of a circular landpad marker in order to estimate the exact flight distance between the quadroto...

1 INTRODUCTION Micro Aerial Vehicles (MAV) form a comparably new area of aeronautical research. This type of aircraft is defined by takeoff weights typically less than 500 g and very small dimensions, e.g. wingspans under 50 cm. Intense research is conducted worldwide to further reduce MAV mass and size (e.g. Within this paper, this term is expanded to also include so-called miniature unmanned ...

To develop an advanced muscle–computer interface (MCI) based on surface electromyography (EMG) signal, the amplitude estimations of muscle activities, i.e., root mean square (RMS) and mean absolute value (MAV) are widely used as a convenient and accurate input for a recognition system. Their classification performance is comparable to an advanced and high computational timescale methods, i.e., ...

MAV (Micro Aerial Vehicle) is nonlinear plant, it is difficult to obtain stable control for MAV attitude due to uncertainties. The purpose of this paper is to propose one robust 、 stable control strategy for MAV to accommodate system uncertainties, variations, and external disturbances. In this paper, an interval type II fuzzy sliding-mode controller combined with PSO algorithm (ITIIFSMC-PSO) i...
