Present to your audience. Do you really want to delete this prezi? In terms of time efficiency, this scenario has a two advantages: firstly, given that the speed of the drone largely exceeds that of human rescuers—especially considering the uneven and steep ground they are typically moving on—, the beacon localization time can be significantly reduced; secondly, the search for any subsequent buried people can happen in parallel while the rescue team is busy digging, not to mention that a swarm of drones can prove even more effective in compressing the average finding time.
Development of such a system is a highly interdisciplinary task, demanding for competences in mechatronics, automation, control, measurements, signal processing, and tackling of possible legal issues. To date, there are no examples of similar systems on the market, although there are very recent and ongoing research efforts with similar objectives triggered by the recent fast developments in the market of small UAVs.
We reckon that this is the right time for starting research activities in this field within our University, for three reasons: i technology readiness: small robotic drones and UAVs can be realized at reasonable costs; ii competences: after the recent rearrangement of university Departments, we have now most of the competences of interest in this field in a contiguous space Povo 2 building, hosting both the Dpt.
D-FAB project aims at developing a vertical takeoff and landing VTOL drone for assisting Alpine rescue teams in locating avalanche buried and semi-buried people, with the aim of shortening the localization time thus improving the chances of saving their lives. The project has to solve a number of problems, relevant to different disciplines: Drone design. Sturdy, rugged drone mechanical design, suitable for operation in harsh winter alpine conditions.
Typical operating conditions—together with the characteristics of the payload needed for victims localization—impact on the system design at different levels, from the power storage, to the resistance against water and humidity, low temperatures, and to the ability to fly in a controllable and stable way even in presence of significant winds as it may be the case on high altitude scenarios.
Also thanks to the expertise of DII members in designing and realizing autonomous vehicles and control systems also considering aerodynamics aspects [3—6], and in manufacturing structural components in composite materials, it will be realized a prototype of a lightweight, resistant, and foldable VTOL drone structure—which is not yet available as off-the-shelf solution. Scenario and ego-state reconstruction, by applying sensor fusion techniques to a set of lower level measurements, including GPS location, inertial navigation, height-over-ground detection, apparent wind direction and intensity, ground morphology.
More precisely, this will be addressed by developing algorithms that exploit computer vision and image processing techniques to deal with the huge quantity of information that UAV collects possibly offloaded to a ground station for elaboration [22,23]. It will consist in the design of a nonlinear filter, which combines image gradient features and Gaussian process GP modeling.
The image gradient features allow capturing detailed information regarding the structure of the investigated classes of objects human figures, semi-buried personal items whereas the GP model fed with image gradient features permits to yield a statistical estimate of the presence of objects of interest for any position within the image. Accordingly, the GP model will be trained with a library of predefined objects with adequate spatial resolutions.
In order to speed up the algorithm, a fast and simple screening technique based on application of adaptive image threshold will be adopted in order to reduce the areas to be analyzed by the detector. Localization of buried and semi-buried avalanche victims, possibly using standard ARVA beacons together with image analysis and classification, by using the very approach described in B and coherently fused with the other sensed data, for incrementally updating a map of the avalanche area, marking the presence of beacons, items skis, backpacks , and semi-buried human figures.
Regarding beacon signal analysis, there are still few examples of automatic searching. Inoltre, sembra che la soppressione per le TEOAEs abbia nelle donne un valore predittivo positivo maggiore, mentre nei maschi un valore predittivo negativo maggiore.
First, the underlying pathophysiology remains obscure. Patients reporting tinnitus have been found to exhibit defective medial olivocochlear bundle MOCB function, when assessed through contralateral suppression of otoacoustic emissions OAEs by acoustic stimuli in a number of studies However, some researchers, who adopted substantially different methods of analysing and evaluating their results, have failed to establish a connection between MOCB dysfunction and tinnitus generation 9 , A review of the relevant literature 11 concluded that reduction of the neural efferent control of the cochlear amplifier seems to represent one of the possible pathophysiological abnormalities that may be related to tinnitus in normal hearing patients.
Second, there is no objective examination that can measure or simply verify the existence of tinnitus. The aim of this study was to assess contralateral suppression of OAEs by acoustic stimulus as a potential tool for an objective investigation of tinnitus and investigate the roles of gender, age and tinnitus bi- or uni-laterality as possible confounding factors. Another aim of the study was to investigate any frequency-related differences that may reveal an association between high-frequency tinnitus and suppression malfunction at higher frequencies.
Relevant implications regard both diagnostic and therapeutic assessment of tinnitus through focal or pharmacological manipulation of the olivocochlear system Tinnitus was lateralised to the right in 15, to the left in 26 and bilateral in 37 of normal hearing individuals.
Cerebral dominance was considered as a potential confounding factor because of its presumed role in the lateralisation of the contralateral suppression of OAEs
