Using an Autonomous Underwater Vehicle (AUV) for close-proximity operations (e.g., close to the seafloor, a vessel, or divers) requires robust, precise vehicle control. When performing joint human-robot operations, a Robotic Diver Assistant can perform tasks such as tool carrying, worksite illumination, ...
Divers have to perform technical underwater tasks in dangerous and unstructured environments. To reduce a diver's workload and improve overall safety, an underwater robotic assistant (UWRA) could be deployed with the diver. The UWRA could assist the diver in navigation, quickly ferry tools from the ...
Cognitive signal processing has been intensively studied over the past years. Nevertheless, cognitive sonar systems only draw little attention in the research community. In this paper the signal processing of a cognitive sonar system for diver detection is shown in detail. It is inspired by the target-detection ...
To find acoustic signature of diver equipped with atmospheric diving suit (ADS), a logarithmic normalized frequency-domain multi-band matched-filter (LNMF) algorithm is presented, which can mitigate the influence of the background noise and short-duration transient interference. Based on experimental ...
This demo presents a suite of serious Kinect™ - based games for rehabilitation. The game embodies three metaphors and corresponding game mechanics, for three exercise movements: elbow flexion and extension (fisherman), shoulder abduction and adduction (moon spaceship), and knee flexion and extension ...
A floating element is for forming a modularly constructed buoyancy system. The floating element is provided with a cavity. At least the first side face of the floating element is provided with at least one first cut-out which, at its first end, is connected to a first channel whose mouth is in a first ...
According to embodiments of the present invention, a bioreactor for growing photoautotrophic organisms is provided. The bioreactor includes a vessel configured to receive the photoautotrophic organisms, the vessel having a longitudinal axis, which a circumferential wall extends around said axis, wherein ...
A cage net (3) includes a plurality of screen sheets (31) each having an upper section (311) and a tapered lower section (312). The upper sections (311) are interconnected side by side to form a surrounding wall (300), and the lower sections (312) are interconnected side by side to form a bottom wall ...
The present invention relates to a control unit (116) for a game or fish feeder (100). The control unit (116) is mounted on the feeder (100) and comprises: means (130) for controlling the powering of a drive unit (110) of said feeder (100) for controlled output of feed from the feeder (100); a wireless ...
One object is to provide a fishing spinning reel which ensures the concentricity of the spool shaft (3a) with respect to the pinion gear (8) and enables the spool shaft to be smoothly and accurately reciprocated back and forth without rattling during rotational operation of the handle (5). The fishing ...
The invention concerns a fish-bait binding method, wherein a thread (51) is pulled through the centre of a bait and loose ends of the thread are connected on the outer side of the bait and are shortened to proper length. Loose ends of the thread (51) with a welding component are connected on the outer ...
A technique facilitates the anchoring and use of a downhole tool. The technique may be utilized with operations in which fluid is pumped or otherwise flowed through a tubular to the downhole tool. The operations are performed after the downhole tool has been fixed relative to the wellbore and while ...
Gas generating and releasing articles consisting essentially of a polymer and a gas generating solid dispersed therein are described. The article generates a controlled fast and followed by a slow release gas in response to moisture.
Background Non Small Cell Lung Cancer is a highly heterogeneous tumor. Histologic intratumor heterogeneity could be ‘major’, characterized by a single tumor showing two different histologic types, and ‘minor’, due to at least 2 different growth patterns in the same tumor. Therefore, a morphological ...
Embryogenesis is an important stage of marine invertebrates with bi-phasic life cycles, as it conditions their larval and adult life. Throughout embryogenesis, phospholipids (PL) play a key role as an energy source, as well as constituents of biological membranes. However, the dynamics of PL during ...
Background Soft-shelled turtle iridovirus (STIV) causes severe systemic disease in farmed soft-shelled turtles (Trionyx sinensis). More efficient methods of controlling and detecting STIV infections are urgently needed. Methods In this study, we generated eight single-stranded DNA (ssDNA) aptamers ...
Ponds throughout the world are subjected to a variety of management measures for purposes of biodiversity conservation. Current conservation efforts typically comprise a combination of multiple measures that directly and indirectly impact a wide range of organism groups. Knowledge of the relative impact ...
Pathogen density and genetic diversity fluctuate in the outside-host environment during and between epidemics, affecting disease emergence and the severity and probability of infections. Although the importance of these factors for pathogen virulence and infection probability has been acknowledged, ...
Livestock-associated bacteria with resistance to two or more antibiotic drug classes have heightened our awareness for the consequences of antibiotic consumption and spread of resistant bacterial strains in the veterinary field. In this study we assessed the prevalence of concomitant colonization with ...
Feeding restriction, as a trigger for compensatory growth, might be considered an alternative viable strategy for minimizing waste as well as production costs. The study assessed whether juvenile redclaw crayfish Cherax quadricarinatus (initial weight 0.99 ±0.03 g) was able to compensate for feeding ...
