Sport is one of the best ways to promote the social integration of people affected by physical disability, because it helps them to increase their self-esteem by facing difficulties and overcoming their disabilities. Nowadays, a large number of sports can be easily played by visually impaired and blind athletes without any special supports, but, there are some disciplines that require the prese...

Abstract The objective was to evaluate the impact of sow location, within farrowing room, on reproduction during periods heat stress. Data were collected 1,866 sows at a 3,600-sow commercial farm in eastern North Carolina from May August 2021. In buildings, evaporative cool cell pads cooled air entering hallway. Cooled air, hallway, then entered rooms through inlets front room and pulled by fan...

Achieving adequate coverage with high gain antennas is key to realizing the full promise of the wide bandwidth available at mm/cm bands. We report extensive indoor measurements at 28 GHz, with over 1000 links with and without Line-of-Sight (LOS) using a specialized narrowband channel sounder, capable of reliable measurements up to 171 dB path loss to characterize 90% coverage. Azimuthal power s...

The mesencephalic locomotor region (MLR), which includes the pedunculopontine nucleus (PPN) and the cuneiform nucleus (CN), has been recently identified as a key structure for locomotion and gait control in mammals. However, the function and the precise anatomy of the MLR remain unclear in humans. To study the lateral mesencephalus, we used fMRI in 15 right-handed healthy volunteers performing ...

An increasing number of mobile devices are capable of automatically sensing and recording rich information about the surrounding environment. Spatial locations of such data can help to better learn about the environment. In this work, we address the problem of identifying the locations visited by a mobile device as it moves within an indoor environment. We focus on devices equipped with odometr...

This paper proposes a simple method for localization using an electronic compass. Electronic compasses are often used to detect the heading of mobile robots. However, electronic compasses have one drawback when used inside a building: they can easily be disturbed by electromagnetic sources (e.g., power lines) or large ferro-magnetic structures (e.g., bookshelves). However, this paper introduces...

This paper applies acoustic principles and a novel scanning method motivated by acoustic flow to recognize retro-reflectors directly from sonar echoes while performing drive-by scanning. Right-angle corners and cylinders form specular retro-reflectors that produce strong echoes whose features can be easily identified. A multi-point sonar produces a point process whose density encodes the echo a...

This work considers the problem of calibrating a distributed multi-camera system. As opposed to traditional multi-camera systems, such as stereo heads, in a distributed network the "elds-of-view do not all overlap. Our novel method uses a grid of domino calibration targets. We also describe a novel grid-"nding algorithm, to expedite the location of image-to-world correspondences. Experiments co...
