This paper presents a collaborative system made up of a Wireless Sensor Network (WSN) and an aerial robot, which is applied to real-time frost monitoring in vineyards. The core feature of our system is a dynamic mobile node carried by an aerial robot, which ensures communication between sparse clusters located at fragmented parcels and a base station. This(More)
This paper describes the design, construction and validation of a mobile sensory platform for greenhouse monitoring. The complete system consists of a sensory system on board a small quadrotor (i.e., a four rotor mini-UAV). The goals of this system include taking measures of temperature, humidity, luminosity and CO2 concentration and plotting maps of these(More)
8 The coverage path planning (CPP) problem, is a problem belonging to a subfield of motion planning where the goal is to compute a complete coverage trajectory from initial to final position, within the robot workspace subjected to a set of restrictions. This problem has a complexity NP-complete, and has no general solution. Moreover, there are very few(More)
Emergence of antibiotic resistant pathogens is changing the way scientists look for new antibiotic compounds. This race against the increased prevalence of multi-resistant strains makes it necessary to expedite the search for new compounds with antibiotic activity and to increase the production of the known. Here, we review a variety of new scientific(More)
BACKGROUND Physiological hormone adaptation to a prolonged and submaximum exercise is not well known. The present study was designed to evaluate changes in plasma levels of beta-endorphin and ACTH before and after a 4 hour pedestrian race. SUBJECTS AND METHOD Fourteen amateur athletes enrolled in a 4-hour race were studied. Beta-endorphin and ACTH(More)
BACKGROUND Cinacalcet, a novel calcimimetic, simultaneously lowers parathyroid hormone (PTH), phosphorus (P), calcium (Ca) and Ca x P in patients who are on dialysis with secondary hyperparathyroidism (sHPT) associated with CKD. Previous studies have required cinacalcet to be administered during the dialysis session and at the same time on non-dialysis(More)
Aerial images are useful tools for farmers who practise precision agriculture. The difficulty in taking geo-referenced high-resolution aerial images in a narrow time window considering weather restrictions and the high cost of commercial services are the main drawbacks of these techniques. In this paper, a useful tool to obtain aerial images by using low(More)
This work presents an innovative solution for moisture monitoring in precision farming by using ground vehicles. The real innovation lies on using non-common robots such as spherical robots. This particular vehicle has turned out to be suitable for performing monitoring tasks in crop fields mainly due to its spherical shape, small size, low weight and(More)
