description: Simple linear joint controllers are still used in typical industrial robotic systems. The use of these controllers leads to non-negligible dynamic path deviations for applications that require high path accuracy. These deviations result from the strong influence of non-linearities, such as multi-body dynamics and gear friction. Sophisticated nonlinear control algorithms, known from the literature, are still not used because they usually require an expensive change of the control architecture. Therefore, different compensation methods are compared in this paper which reduce the path deviations by correction of the desired trajectory'. This means that no torque interface is required, only an interface for path corrections is necessary. Such an interface normnally exists so that the methods can simply be implemented within standard industrial controls. Using the industrial robot Siemens manutec-r15 the methods are experimentally compared with respect to their efficiency and practical applicability. Starting from this, one method is chosen for application to the state-of-the-art industrial robot KUKA KR15. The algorithm is based on a complete nonlinear dynamic model of the robot. It is integrated into the standard control KRC1. The experimental results prove the efficiency and the industrial applicability of the method.

Proposal of a two-qubit quantum phase gate for quantum photonic integrated circuits
Creators: name: Johne, Robert
name: Fiore, Andrea
Publisher: name: arXiv
Year: 2012
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We propose a protocol for two-qubit quantum phase gate based upon reflection of photon pulses from a quantum dot in a cavity. Depending on the state of the quantum dot the reflected photons acquire a conditional phase shift. The key ingredient is the ultrafast control of the quantum dot energies by electric fields, which allows for tuning the exciton and biexciton successively into resonance with the cavity mode. The complete dynamics of the gate are simulated revealing a fidelity of about 0.9. The proposed scheme uses position-coding and is therefore well suited to the implementation in an integrated photonic quantum processor.

Habitable Planets Around White and Brown Dwarfs: The Perils of a Cooling Primary

Year: 2012

subject: FOS: Physical sciences

description: White and brown dwarfs are astrophysical objects that are bright enough to support an insolation habitable zone (IHZ). Unlike hydrogen-burning stars, they cool and become less luminous with time, and hence their IHZ moves in with time. The inner edge of the IHZ is defined as the orbital radius at which a planet may enter a moist or runaway greenhouse, phenomena that can remove a planet's surface water forever. Thus, as the IHZ moves in, planets that enter it may no longer have any water, and are still uninhabitable. Additionally, the close proximity of the IHZ to the primary leads to concern that tidal heating may also be strong enough to trigger a runaway greenhouse, even for orbital eccentricities as small as 10^-6. Water loss occurs due to photolyzation by UV photons in the planetary stratosphere, followed by hydrogen escape. Young white dwarfs emit a large amount of these photons as their surface temperatures are over 10^4 K. The situation is less clear for brown dwarfs, as observational data do not constrain their early activity and UV emission very well. Nonetheless, both types of planets are at risk of never achieving habitable conditions, but planets orbiting white dwarfs may be less likely to sustain life than those orbiting brown dwarfs. We consider the future habitability of the planet candidates KOI 55.01 and 55.02 in these terms and find they are unlikely to become habitable.

description: Human resource management (HRM) plays an important role in providing better management for nonprofit organizations (NPOs). Yet little is known about what influences their human resource practices. After discussing how the strategic and human-resource-based theoretical approaches are appropriate for analyzing HRM in NPOs, the authors explore the current nonprofit literature to identify the specific characteristics of strategic orientations and human resources in NPOs. As a result, the authors propose an analytical framework that is differentiated into four HRM types. This framework enables a better understanding of the relationship between the specific characteristics of NPOs and the architecture of HRM. © 2010 SAGE Publications.

Young, Massive Star Candidates Detected throughout the Nuclear Star Cluster of the Milky Way

description: Aims. Young, massive stars have been found at projected distances R < 0.5 pc from supermassive black hole, Sgr A* at the center of our Galay. In recent years, increasing evidence has been found for the presence of young, massive stars also at R > 0.5 pc. Our goal in this work is a systematic search for young, massive star candidates throughout the entire region within R ~ 2.5 pc of the black hole. Methods. The main criterion for the photometric identification of young, massive early-type stars is the lack of CO-absorption in the spectra. We used narrow-band imaging with VLT/ISAAC to search for young, massive stars within ~2.5 pc of Sgr A*. Results. We have found 63 early-type star candidates at R < 2.5 pc, with an estimated erroneous identification rate of only about 20%. Considering their K-band magnitudes and interstellar extinction, they are candidates for Wolf-Rayet stars, supergiants, or early O-type stars. Of these, 31 stars are so far unknown young, massive star candidates, all of which lie at R>0.5pc. The surface number density profile of the young, massive star candidates can be well fit by a single power-law, with Gamma = 1.6 +- 0.17 at R < 2.5 pc, which is significantly steeper than that of the late-type giants that make up the bulk of the observable stars in the NSC. Intriguingly, this power-law is consistent with the power-law that describes the surface density of young, massive stars in the same brightness range at R < 0.5 pc. Conclusions. The finding of a significant number of newly identified early-type star candidates at the Galactic center suggests that young, massive stars can be found throughout the entire cluster which may require us to modify existing theories for star formation at the Galactic center. Follow-up studies are needed to improve the existing data and lay the foundations for a unified theory of star formation in the Milky Way's NSC.

description: MOE Key Lab of Liquid Structure and Heredity of Materials, Institute of Materials Joining, Shangdong University, 73 Jingshi Road, Jinan 250061, People's Republic of China This paper introduces an intelligent system for monitoring and recognition of process disturbances during short-circuiting gas-metal arc welding. It is based on the measured and statistically processed data of welding electrical parameters. A 12-dimensional array of process features is designed to describe various welding conditions and is employed as input vector of the intelligent system. Three methods, such as fuzzy c-means, neural network and fuzzy Kohonen clustering network are used to conduct process monitoring and automatic recognition. The correct recognition rates of these three methods are compared.

description: We study the anomalous Hall effect in binary alloys between the group-10 elements Ni and Pt. It is observed that the ordinary Hall effect is negative (electron-like) at any composition of the alloy. The extraordinary Hall effect is also negative except in the vicinity of the ferromagnetic quantum critical point. Close to the critical point the sign of the extraordinary Hall effect can be changed to positive (hole-like) by tuning either the temperature or the composition of the alloy. We attribute such an "anti-ordinary" Hall effect with opposite signs of the ordinary and the extraordinary contributions to a Berry phase singularity, moving away from the Fermi energy with increasing the ferromagnetic exchange energy.

description: The usual classical behaviour of S = 3/2, B-site ordered double perovskites generally results in simple, commensurate magnetic ground states. In contrast, heat capacity and neutron powder diffraction measurements for the S = 3/2 systems La2NaB'O6 (B' = Ru, Os) reveal an incommensurate magnetic ground state for La2NaRuO6 and a drastically suppressed ordered moment for La2NaOsO6. This behaviour is attributed to the large monoclinic structural distortions of these double perovskites. The distortions have the effect of weakening the nearest neighbour superexchange interactions, presumably to an energy scale that is comparable to the next nearest neighbour superexchange. The exotic ground states in these materials can then arise from a competition between these two types of antiferromagnetic interactions, providing a novel mechanism for achieving frustration in the double perovskite family.

description: The paper is devoted to the geometrical calibration of industrial robots employed in precise manufacturing. To identify geometric parameters, an advanced calibration technique is proposed that is based on the non-linear experiment design theory, which is adopted for this particular application. In contrast to previous works, the calibration experiment quality is evaluated using a concept of the user-defined test-pose. In the frame of this concept, the related optimization problem is formulated and numerical routines are developed, which allow user to generate optimal set of manipulator configurations for a given number of calibration experiments. The efficiency of the developed technique is illustrated by several examples.

description: Considering the increasing amount of data for communication and infotainment applications, fabrication of optical networks and bus systems is a challenging task for production engineering. A two-step manufacturing process for polymer optical waveguides is presented. By improving the highly efficient flexographic printing technology by laser functionalization of the printing tool in combination with a subsequent spray application, high-quality waveguides are accomplished. By adjusting the resulting surface energy of the foil substrate in the first fabrication process, the spray application achieved high-aspect ratio waveguides with a low attenuation of 0.2 dB/cm at 850 nm. © 2017 Society of Photo-Optical Instrumentation Engineers (SPIE).

description: We show that the spin-charge separation predicted for correlated fermions in one dimension, could be observed using polarized photons propagating in a nonlinear optical waveguide. Using coherent control techniques and employing a cold atom ensemble interacting with the photons, large nonlinearities in the single photon level can be achieved. We show that the latter can allow for the simulation of a strongly interacting gas, which is made of stationary dark-state polaritons of two species and then shown to form a Luttinger liquid of effective fermions for the right regime of interactions. The system can be tuned optically to the relevant regime where the spin-charge separation is expected to occur. The characteristic features of the separation as demonstrated in the different spin and charge densities and velocities can be efficiently detected via optical measurements of the emitted photons with current optical technologies.

description: We have studied the opacity of dust grains at submillimeter wavelengths by estimating the optical depth from imaging at 160, 250, 350, and 500 um from the Herschel Gould Belt Survey and comparing this to a column density obtained from the 2MASS-derived color excess E(J-Ks). Our main goal was to investigate the spatial variations of the opacity due to "big" grains over a variety of environmental conditions and thereby quantify how emission properties of the dust change with column (and volume) density. The central and southern areas of the Orion A molecular cloud examined here, with NH ranging from 1.5X10^21 cm^-2 to 50X10^21 cm^-2, are well suited to this approach. We fit the multi-frequency Herschel spectral energy distributions (SEDs) of each pixel with a modified blackbody to obtain the temperature, T, and optical depth, τ(1200), at a fiducial frequency of 1200 GHz (250 um). Using a calibration of NH/E(J-Ks)for the interstellar medium (ISM) we obtained the opacity (dust emission cross-section per H nucleon), σ_e(1200), for every pixel. From a value of ~ 1X10^-25 cm^2 H^-1 at the lowest column densities that is typical of the high latitude diffuse ISM, σ_e(1200) increases as NH^0.28 over the range studied. This is suggestive of grain evolution. Integrating the SEDs over frequency, we also calculated the specific power P (emission power per H) for the big grains. In low column density regions where dust clouds are optically thin to the interstellar radiation field (ISRF), P is typically 3.7 X 10^-31 W H^-1, again close to that in the high latitude diffuse ISM. However, we find evidence for a decrease of P in high column density regions, which would be a natural outcome of attenuation of the ISRF that heats the grains, and for localized increases for dust illuminated by nearby stars or embedded protostars.

description: In this report the question of education in fair play in football clubs is critically discussed. The results of a representative study of the attitudes of juvenile football players, football coaches and 12-14 year-old pupils towards fair play and violence verify that violence and unfairness are the logical consequences of the comprehension of a sport that is solely or primarily oriented towards success. The longer 12-14 year old juveniles play soccer in a soccer club, the more they are willing to see intentional fouls as fair; thus the more they internalize the moral of “fair foul”. On the basis of these results, the efforts to promote fair play and the chances of an education in fair play are discussed critically. © 1995, Sage Publications. All rights reserved.

Exploring Multiraciality, Power, Privilege, and Oppression: A study on how multiracial students navigate their relationship(s) to socio-political power structures in higher education

description: There is limited research on the experiences of Multiracial college students (Matsumura, 2017). Current Multiracial narratives within higher education focus primarily on personal identity exploration. Far fewer study how Multiracial students maneuver through socio-political power structures. The literature has also not considered how other Multiracial people might influence how Multiracial students come to understand their position(s) within these systems. This study examined Multiracial students’ connection(s) to socio-political power structures within the United States by asking the following question: How do Multiracial college students, who interact with other Multiracial people, navigate their relationship(s) to power, privilege, and oppression? The findings from this study indicated that Multiracial students are navigating their relationships to power, privilege, and oppression within an anti-Blackness, anti-Multiraciality white supremacy paradigm by developing an understanding of the monoracially dominant paradigm they inhabit, coming to understand the roles that are placed on them as Multiracial people within this paradigm, and rejecting notions that constrict their ability to live as a Multiracial person. The findings suggested that Multiracial students are navigating this landscape by finding and/or creating community, maintaining friendships with Multiracial peers, and developing confidence in creating a core way of being.

description: Niemand kann wissen, wie die Zukunft wirklich wird. Die mit der Zukunft unvermeidbar verbundene Ungewissheit erzeugt bei vielen Menschen Zukunftsangst und die Sehnsucht nach Gewissheit. Fiktionen sind offensichtlich ein nützliches Instrument der menschlichen Psychodynamik für die Konstruktion von sicherheitsspendenden mentalen Landkarten und Wegweisern in die Zukunft. Dieses Konzept der psychosozialen Navigation in die Lebenswelt von morgen und übermorgen nannte der für die Theoriebildung der Individualpsychologie sehr wichtige Hans Vaihinger vor mehr als hundert Jahren (1911) „Die Philosophie des Als Ob“. Im vorliegenden Essay weise ich an einigen Beispielen aus der Literatur (Utopie, Dystopie, Science Fiction) sowie aus unterschiedlichen wissenschaftlichen Disziplinen auf einige interessante Zukunftsfiktionen hin. Abschließend werfe ich einen kritischen Blick auf transhumanistische Zukunftsfiktionen im Silicon Valley.

description: The article contributes to the current discourse on learning regions. It aims to identify favourable conditions for policy learning in regions. Supported by the most prominent theories on regional development and innovation, the existence of autonomous policy networks in regions is regarded as a fundamental prerequisite for generating innovations. However, previous research does not clarify how networks have to be organized and linked to the institutional framework inside and outside a region, how actors should interact in networks, and whether competitive or cooperative orientations of actors are more conducive to change. Our theoretical reasoning leads us to the conclusion that learning regions are those that manage to meet different, to a certain degree contradictory, demands regarding structures of networks and actors involved. Successful learning, the generation and implementation of new patterns of politics and new policies depends on specific structural characteristics of networks, but also on actors' cognitive dispositions, orientations, strategies and interactions. Moreover, favourable institutional settings are identified which may induce adequate network structures and support innovative policies. Finally we draw some conclusions for practical regional policy in a 'learning region'.

description: The article focuses on the temporal and epistemic economy connected to the transatlantic travels of the categorical triad of 'race-class-gender'. It looks at conditions and forces that have fuelled the dynamics of the discourse on differences and inequality among women and analyses feminist discourse and its aporias as a particular environment for the travels of theories. Furthermore, it follows the changes the triad of 'race-class-gender' undergoes on its transatlantic route from the United States to a German-speaking context and it outlines the theoretical challenges connected to an intersectional perspective that aims to overcome a theoretical stagnation that itself finds symptomatic expression in the ritual citing of 'race-class-gender'.

description: This article describes the effect of polymer additives in lithium greases on performance and boundary layers of high-speed angular contact ball bearings. High-speed test rigs were used to run grease life tests utilizing five lithium grease variants that were derivatives from the same basic grease composition. While one was used in its plain state, the other four were blended with polymer additives. The test runs showed different operating characteristics of the greases with total service lives (L10) ranging from 139 to 1010 h. Furthermore, the operating temperatures of the greases varied by up to 11 °C. After test run completion, surface hardness was measured on the raceways using a nanoindentation system with a triangular diamond pyramid Berkovich tip and an applied force of 1.5 mN. As a reference, a 'virgin' bearing was studied having not yet been in contact with grease. Thereafter, measurements were performed on samples that had been in contact with the five described greases. It is shown that polymer additives indeed can influence the properties of boundary layers, thereby affecting the bearing's service life and friction.

description: A "pulsar timing array" (PTA), in which observations of a large sample of pulsars spread across the celestial sphere are combined, allows investigation of "global" phenomena such as a background of gravitational waves or instabilities in atomic timescales that produce correlated timing residuals in the pulsars of the array. The Parkes Pulsar Timing Array (PPTA) is an implementation of the PTA concept based on observations with the Parkes 64-m radio telescope. A sample of 20 millisecond pulsars is being observed at three radio-frequency bands, 50cm (~700 MHz), 20cm (~1400 MHz) and 10cm (~3100 MHz), with observations at intervals of 2 - 3 weeks. Regular observations commenced in early 2005. This paper describes the systems used for the PPTA observations and data processing, including calibration and timing analysis. The strategy behind the choice of pulsars, observing parameters and analysis methods is discussed. Results are presented for PPTA data in the three bands taken between 2005 March and 2011 March. For ten of the 20 pulsars, rms timing residuals are less than 1 microsec for the best band after fitting for pulse frequency and its first time derivative. Significant "red" timing noise is detected in about half of the sample. We discuss the implications of these results on future projects including the International Pulsar Timing Array (IPTA) and a PTA based on the Square Kilometre Array. We also present an "extended PPTA" data set that combines PPTA data with earlier Parkes timing data for these pulsars.

Prediction of losses in belt-type continuously variable transmission due to sliding between belt and disc

description: The efficiency of belt-type continuously variable transmission (CVT) - apart from the power consumption of auxiliary systems such as hydraulics - predominantly depends on the energy dissipated during sliding at the belt-disc contacts. These sliding motions are a consequence of elastic deformations and misalignments because of clearances, resulting in a so-called spiral path of the belt elements on the discs and hence tangential and radial sliding motions. The performance of such systems can be predicted through an iterative computation by numerically solving a set of differential equations for the forces and motions coupled with a finite-element computation of the deformations. A comparison with elaborate measurements of deflections, belt motions, and losses shows that a relatively simple modified Coulomb type friction model with a steep gradient through the origin delivers sufficiently accurate results. The computations reveal the existence of 'locked' zones with extremely low 'creeping' motions. Thus, the mechanisms of power transmission in belt-type CVT are better understood and designers have a validated tool to optimize shaft and disc geometry concerning maximum efficiency.

description: The current study assesses how neighborhood-level LGBTQ prevalence, concentrated disadvantage, residential mobility, and racial diversity and the micro-spatial presence of LGBTQ establishments uniquely and jointly predict anti-LGBTQ hate crime. Extant research utilizes neighborhood-level explanations of crime to understand anti-LGBTQ hate crime but does not account for the influence of opportunity at the micro-place, and particularly the role of LGBTQ establishments as facilitators of anti-LGBTQ crime opportunity, for understanding where anti-LGBTQ hate crimes occur. The current study uses official hate crime data, demographic data from the US Census Bureau, and publicly available data on the location of LGBTQ-centered establishments to assess the roles of neighborhood-level and micro-spatial predictors of anti-LGBTQ hate crime in Washington, DC from 2017 to 2019. Results suggest that more anti-LGBTQ hate crimes occur in places with higher LGBTQ prevalence, more residential mobility, and more LGBTQ establishments. Residential mobility also interacts with the presence of LGBTQ establishments. Findings indicate that LGBTQ establishments are associated with more risk of hate crime in less mobile (i.e., more stable) neighborhoods.

Quantified H i Morphology VII: The Morphology of Extended Disks in UV and H i

description: Extended UltraViolet (xuv) disks have been found in a substantial fraction of late-type --S0, spiral and irregular-- galaxies. Similarly, most late-type spirals have an extended gas disk, observable in the 21cm radio line (HI). The morphology of galaxies can be quantified well using a series of scale-invariant parameters; Concentration- Asymmetry-Smoothness (CAS), Gini, M20, and GM parameters. In this paper, we compare the quantified morphology and effective radius (R50) of the Westerbork observations of neutral Hydrogen in Irregular and Spiral galaxies Project (WHISP) HI maps to those of far-and near-ultraviolet images obtained with galex, to explore how close the morphology and scales of HI and UV in these disks correlate. We find that xuv disks do not stand out by their effective radii in UV or HI. However, the concentration index in FUV appears to select some xuv disks. And known xuv disks can be identified via a criterion using Asymmetry and M20; 80% of xuv disks are included but with 55% contamination. This translates into 61 candidate xuv disk out of our 266 galaxies, (23%) consistent with previous findings. We consider three scenarios; tidal features from major mergers, the typical extended Hi disk is a photo- dissociation product of the xuv regions and both Hi and UV features originate in cold flows fueling the main galaxy. We define extended HI and UV disks based on their concentration (CHI > 5 and CFUV > 4 respectively), but note that these two subsamples never overlap in the WHISP sample. This appears to discount a simple photo-dissociation origin of the outer HI disk. Previously, we identified the morphology space occupied by ongoing major mergers. Known xuv disks rarely reside in the merger dominated part of HI morphology space but those that do are Type 1. This suggests cold flows as the origin for the xuv complexes and their surrounding HI structures.
