In recent years, a growing number of studies have demonstrated that individuals can exert higher motivation when working in group compared to individually. This is particularly true for less capable, inferior members. To aggregate these findings and examine preconditions as well moderating influences on gains members, the authors conducted meta-analysis (17 studies, N=2,240). Results indicated overall gain effect members observed moderate significant (g=.60). Moderator analyses revealed...
This paper presents a new robot controller for space telerobotics missions specially designed to meet the requirements of KONTUR-2, German & Russian mission that addressed scientific and technological questions future planetary explorations. In Earth ISS have been used as test-bed evaluate demonstrate technology real-time telemanipulation from space. During August 2015' experiments campaign, cosmonaut teleoperated manipulator located in Germany, using force-feedback joystick segment...
Leptin is known to regulate food intake and energy expenditure. Since loss of appetite bodyweight are important signs symptoms major depression we studied leptin plasma concentrations in both depressed patients (n = 24) suffering from a healthy control group 33). To rule out the possibility inferences with other endocrine parameters be changed or suspected related leptin, also cortisol, insulin, growth hormone (GH) GH-binding protein (GHBP). We found that did not differ between controls....
Hypercortisolism is a frequent endocrine sign in major depression and cortisol well-known anti-insulinergic hormone. Impaired oral glucose tolerance has already been described depression. However, thus far no information available on spontaneous, circadian insulin secretion patients. We studied 26 depressed inpatients along with 33 age- sex-matched controls. Blood samples were collected at 30-minute intervals over period of hours (h) for estimation cortisol, glucose. No differences 24 h...
In the present study, a vibrotactile feedback device for spatial guidance was evaluated in tracking task paradigm. Participants (N = 18) had to translate and rotate virtual objects according vs. verbal cues without visual information. Both types of were using objective performance data (i.e. speed, accuracy) as well subjective judgments. Results indicate that distinguishing during translational more difficult when being guided by compared feedback. Nevertheless, individuals with showed...
Current space exploration roadmaps envision exploring the surface geology of celestial bodies with robots for both scientific research and in situ resource utilization. In such unstructured, poorly lit, complex, remote environments, automation is not always possible, some tasks, as geological sampling, require direct teleoperation aided by force-feedback (FF). The operator would be on an orbiting spacecraft, poor bandwidth, high latency, packet loss from orbit to ground mean that safe,...
Depression, aging and female gender are associated with increased diurnal concentrations of total plasma cortisol. For the physical effects hypercortisolemia, however, it is generally assumed that free rather than cortisol importance. Herein, we report a mathematical approach to determine on basis cortisol, corticosteroid binding-globulin (CBG) albumin concentrations. This was used re-evaluate two sets data in order estimate effect depression as well upon Comparing male depressed patients...
A mathematical model has been developed to calculate the three dimensional and instationary temperature field in strand during continuous casting. The numerical algorithm computer program were tested by application Neumann problem for which an analytical solution is available. It was found that this reproduced quite closely even if relatively coarse finite difference meshes are used. An based on of inverse heat conduction applied adjust transfer coefficients using results surface...
The potential areas of application for robots have gradually extended beyond the classical industrial settings in large-scale enterprizes: nowadays, integration into daily life has become a central development robotics. Here, one major challenge is physical interaction with unknown and/or changing environments. Such an requires knowledge exchanged contact forces and torques. To this end, robotic systems are typically equipped force/torque sensors at wrist. By using force control schemes that...
Sending humans to Mars' surface build habitats is, for now, prohibitively dangerous and costly. An alternative is have in orbiters, teleoperating robots on Mars construct habitats, deferring human arrival until these are finished. This paper describes the Kontur-2 experiments, which feasibility of this scenario was tested with International Space Station as an orbiter, a cosmonaut operating force-feedback joystick input device teleoperation, Earth planet where teleoperated robot located. In...
There is an age-associated decline in the activity of GH-IGFs system. However, so far, it has not been studied, whether this somatotrophic might be preventable by intensive exercising. We studied 11 elderly male (50-78 years) marathon runners and 10 age-matched (52-73 sedentary controls to evaluate plasma concentrations GH, total free IGF-I IGF-II IGF-binding protein-1 (IGFBP-1), IGFBP-2, IGFBP-3 insulin. When comparing two groups (runners vs controls) no differences were found GH (1.0 +/-...
In the present paper, we propose a novel system-driven adaptive shared control framework in which autonomous system allocates authority among human operator and itself. Authority allocation is based on metric derived from Bayesian filter, being adapted online according to real measurements. this way, time-varying measurement noise characteristics are incorporated. We stability proof for proposed architecture with allocation, includes time delay communication channel between robot....
Future challenges in teleoperation arise from a new complexity of tasks and constraints unstructured environments. In industrial applications as nuclear research facilities, the operator has to manipulate large objects whereas medical robotics requires extremely high precision. last decades, optimized transparency setups through accurate hardware, higher sampling rates, improved sensor technologies. To further enhance performance telemanipulation, idea haptic augmentation been briefly...
The success of many space missions critically depends on human capabilities and performance. Yet, it is known that sensorimotor performance degraded under conditions weightlessness. Therefore, astronauts prepare for their in simulated weightlessness water. In the present study, we investigated (induced by shallow water immersion) whether can be improved choosing appropriate haptic settings human-machine interface (e.g., motion damping). Twenty-two participants performed basic aiming tracking...
Introduction: Hypersalivation is known as a frequent, disturbing, and socially stigmatizing side effect of therapy with the atypical antipsychotic clozapine. It has been shown that addition anticholinergic pirenzepine able to reduce clozapine-induced hypersalivation, probably by blocking M4-receptors. Nevertheless, pharmacokinetic interaction between both compounds cannot be excluded. Methods: In this pilot study, 29 schizophrenic patients (ICD-10; 51.7 % female; age: 36.7 ± 8.7 years [mean...
This work presents an evaluation study of two different collision feedback modalities for virtual assembly verification: visual and force feedback. Forty-three subjects performed several tasks (peg-in-hole, narrow passage) designed with levels difficulty. The used haptic rendering algorithm is based on voxel point data-structures. Both objective - time performance subjective measures have been recorded analyzed. comparison the revealed a clear highly significant superiority in scenarios....
Abstract Future space missions envisage human operators teleoperating robotic systems from orbital spacecraft. A potential risk for such is the observation that sensorimotor performance deteriorates during spaceflight. This article describes an experiment on in two-dimensional manual tracking different stages of a mission. We investigated whether there are optimal haptic settings human-machine interface microgravity conditions. Two empirical studies using same task paradigm with force...
