The IBM Streams Processing Language (SPL) is the programming language for InfoSphere® Streams, a platform analyzing Big Data in motion. By "Big motion," we mean continuous data streams at high data-transfer rates. InfoSphere processes such with both throughput and short response times. To meet these performance demands, it deploys each application on cluster of commodity servers. SPL abstracts away complexity distributed system, instead exposing simple graph-of-operators view to user. has...
The topic of motivation is a crucial issue for various human-robot interaction (HRI) scenarios. Interactional aspects can be studied in human-human (HHI) and build the basis modeling robot's interactional conduct. Using an ethnographic approach we explored factors relevant formation motivation-relevant processes indoor-cycling activity. We propose interactive, action-based model HRI that has been implemented autonomous robot system tested during long-term study. based on micro-analyses human...
Adjusting a resulting surface integrity prior to manufacturing process is big challenge in production engineering. One approach solve this the methodology of signatures. To develop comprehensive signature for Sinking EDM (S-EDM) it necessary describe relationship between applied material loadings and modifications workpiece rim zone. It generally considered that S-EDM an electro-thermal process, which significantly characterized by heat flux due spark plasma. Accordingly, main during are...
Abstract Learning and matching a user’s preference is an essential aspect of achieving productive collaboration in long-term Human–Robot Interaction (HRI). However, there are different techniques on how to match the behavior robot preference. The can be adaptable so that user change robot’s one’s need, or adaptive autonomously tries its Both types might decrease gap between actual system behavior. Level Automation (LoA) both methods. Either controls interaction, control. We present study...
Most social robot behaviors in human-robot interaction are designed to be polite, but there is little research about how or when a could impolite, and if that may ever beneficial. We explore the potential benefits tradeoffs of different politeness levels for an exercise context. impolite polite phrases trainer conducted 24-person experiment where people squat front as it uses (im)polite encourage them. found participants exercised harder felt competitive with robot, while was friendly,...
Autonomous navigation in unstructured environments like forest or country roads with dynamic objects remains a challenging task, particularly respect to the perception of environment using multiple different sensors. The problem has been addressed from both, computer vision community as well researchers working laser range finding technology, Velodyne HDL-64. Since cameras and LIDAR sensors complement one another terms color depth perception, fusion both is reasonable order provide images...
In recent years vehicles have been equipped with more and sensors for environment perception. Among these are cameras, RADAR, single-layer multi-layer LiDAR. One key challenge the fusion of is sensor calibration. this paper we present a novel extrinsic calibration algorithm based on odometry. Given time-synchronized delta poses two our technique recursively estimates relative pose between sensors. The method generic in that it can be used to estimate complete 6DOF poses, given provide...
Service and social robot in public scenarios will face various tasks future applications, such as guiding people or admonishing them to provide assistance convey norms. Robots spaces might also incorporate roles of authority figures who admonish (e.g., security guard robots). However, recent investigations showed that ignore the admonishment robots. Thus, this work, we are looking at reasons why robots based on Cognitive Dissonance Theory (CDT). We present results two consecutive field...
The surface and subsurface conditions of components are significant for their functional properties. Every manufacturing process step changes the condition due to its mechanical, chemical and/or thermal impact. depth affected zone varies different machining operations, is predetermined by parameters characteristics. Furthermore, initial state has a decisive influence on interactions that lead final conditions. aim investigation presented here compare load characteristics over applied...
Redirected walking is a locomotion technique that allows users to naturally walk through large immersive virtual environments (IVEs) by guiding them on paths might vary from the they in real world. While this enables exploration of larger spaces IVE via natural walking, previous work has shown it induces extra cognitive load for users. On other hand, research exposure nature can restore users' diminished attentional capacities and lead enhanced performances. Therefore, aim paper investigate...
Knowledge transfer from higher education instituions (HEI) in Germany faces a dilemma: Although of central importance, bureaucratic hurdles often slow down effective processes and results. However, look behind the scenes - at „backstage“ could shed additional light inspire new research approaches. The mostly hidden dynamics activities also seem worthwhile investigating because it improve mutual understanding between actors administration as well exchange knowledge with external partners....
Abstract Emerging magnetic fields related to the presence of topologically protected spin textures such as skyrmions are expected give rise additional, topology‐related contributions Hall effect. In order doubtlessly identify this so‐called topological effect, it is crucial disentangle from anomalous This necessitates a direct correlation transversal voltage with underlying textures. A novel measurement platform developed that allows acquire high‐resolution Lorentz transmission electron...
The ligaments in coherence with the capsule of hip joint are known to contribute stability. Nevertheless, contribution mechanical properties and gender- or side-specific differences still not completely clear. To date, comparisons other tissues stabilizing pelvis joint, e.g. iliotibial tract, were performed.Hip obtained from 17 human cadavers (9 females, 7 males, 13 left 8 right sides, mean age 83.65 ± 10.54 years). 18 iliofemoral, 9 ischiofemoral pubofemoral prepared. Uniaxial stress-strain...
Temperature field is the main material loading in EDM and responsible for rim zone modifications. For adjusting dedicated surface integrity, it necessary to quantify loading. A direct measurement of temperatures near working area not possible due very high corresponding gradients. Also numerical prediction temperature difficult, because no general model power distribution during process exists. One possibility obtain this inverse simulation. given inner workpiece a heat source with defined...
