description: We present a radio polarization study of SN 1006, based on combined VLA and ATCA observations at 20 cm that resulted in sensitive images with an angular resolution of 10 arcsec. The fractional polarization in the two bright radio and X-ray lobes of the SNR is measured to be 0.17, while in the southeastern sector, where the radio and non-thermal X-ray emission are much weaker, the polarization fraction reaches a value of 0.6 +- 0.2, close to the theoretical limit of 0.7. We interpret this result as evidence of a disordered, turbulent magnetic field in the lobes, where particle acceleration is believed to be efficient, and a highly ordered field in the southeast, where the acceleration efficiency has been shown to be very low. Utilizing the frequency coverage of our observations, an average rotation measure of ~12 rad/m2 is determined from the combined data set, which is then used to obtain the intrinsic direction of the magnetic field vectors. While the orientation of magnetic field vectors across the SNR shell appear radial, a large fraction of the magnetic vectors lie parallel to the Galactic Plane. Along the highly polarized southeastern rim, the field is aligned tangent to the shock, and therefore also nearly parallel to the Galactic Plane. These results strongly suggest that the ambient field surrounding SN 1006 is aligned with this direction (i.e., from northeast to southwest) and that the bright lobes are due to a polar cap geometry. Our study establishes that the most efficient particle acceleration and generation of magnetic turbulence in SN 1006 is attained for shocks in which the magnetic field direction and shock normal are quasi-parallel, while inefficient acceleration and little to no generation of magnetic turbulence obtains for the quasi-perpendicular case.

description: We have examined resolved stellar photometry from HST imaging surrounding 18 high-mass X-ray binary (HMXB) candidates in NGC 300 and NGC 2403 as determined from combined Chandra/HST analysis. We have fit the color-magnitude distribution of the surrounding stars with stellar evolution models. All but one region in NGC 300 and two in NGC 2403 contain a population with an age between 20 and 70 Myr. One of the candidates is the ultraluminous X-ray source (ULX) in NGC 2403, which we associate with a 60 Myr old population. These age distributions provide additional evidence that 16 of these 18 candidates are HMXBs. Furthermore, our results suggest that the most common HMXB age in these galaxies is 40-55 Myr. This preferred age is similar to observations of HMXBs in the Small Magellanic Cloud, providing new evidence of this formation timescale, but in higher metallicity populations. We suggest that this preferred HMXB age is the result of the fortuitous combination of two physical effects. First, this is the age of a population when the greatest rate of core-collapse events should be occurring, maximizing neutron star production. Second, this is the age when B stars are most likely to be actively losing mass. We also discuss our results in the context of HMXB feedback in galaxies, confirming HMXBs as a potentially important source of energy for the interstellar medium in low-mass galaxies.

description: This thesis presents a phytosociological analysis of the current vegetation communities on the western slopes of the Valdivian Coastal Range in South Chile. The goal is to describe the changes undergone by the potential vegetation in the research area, which led to the formation of non-native vegetation units and to a more diverse landscape. The data collection was carried out between the Bonifacio and Hueicolla sectors (de Los Ríos Region) and up to an altitude of 300 m a.s.l. This area corresponds to the region where the Olivillo forest used to be the dominant community. A total of 169 phytosociological relevés was used to survey the vegetation. The area of the relevés ranges between 100 and 400 m2, according to the physiognomical minimal area and to the Braun-Blanquet approach. The collected vegetation data set was used to: i) construct the related full and synoptic tables, and ii) describe the physiognomy, floristic composition, diagnostic species, ecology and distribution of the plant communities. In particular, the diagnostic species were identified by using their fidelity values based on the phi-coefficient as described in the literature. The vegetation units were then classified by means of the Ward’s method and the Euclidean distance. Finally, a detrended correspondence analysis (DCA) was performed to identify the environmental variables with the largest influence on the relevés. The analysis led to the classification of 12 plant communities (11 associations and 1 community) and to the identification of a total amount of 137 species. Out of the 137 species, 76 are endemic and 18 present among the IUCN conservation categories (1 is Endangered, 7 are Vulnerable, 4 are Near Threatened, 4 are Least Concerned, 1 is Data Deficient and 1 is Not Evaluated). The species are distributed over 5 classes, 62 families and 117 genera. The plant communities belong to 2 classes (Molinio-Arrhenatheretea and Wintero-Nothofagetea), 3 orders and 6 alliances. One alliance and 2 associations are newly described: the Libertion chilensis and Agrostio capillariae-Eryngietum paniculatae within Molinio-Arrhenatheretea, and Rubo constricto-Greigietum sphacelatae within Wintero-Nothofagetea. The results of this thesis indicate that: i) the identified units show serial relationships of anthropogenic origin, and ii) human activity favours the development of native and non-native permanent communities in the research area. Finally, they can be used for the selection of areas suitable for ecological restoration and landscape management.

description: Smart services serve customers and their individual, continuously changing needs; information and communications technology enables such services. The interactions between customers and service providers form the basis for co-created value. A growing interest in smart services has been reported in the literature in recent years. However, a categorization of the literature and relevant research fields is still missing. This article presents a structured literature search in which 109 relevant publications were identified. The publications are clustered in 13 topics and across five phases of the lifecycle of a smart service. The status quo is analyzed, and a heat map is created that graphically shows the research intensity in various dimensions. The results show that there is diverse knowledge related to the various topics associated with smart services. One finding suggests that economic aspects such as new business models or pricing strategies are rarely considered in the literature. Additionally, the customer plays a minor role in IS publications. Machine learning and knowledge management are identified as promising fields that should be the focus of further research and practical applications. Concrete ideas for future research are presented and discussed and will contribute to academic knowledge. Addressing the identified research gaps can help practitioners successfully provide smart services.

description: In this paper, the aeroelastic modeling and conceptual flutter analysis of a simple 2-D box wing is investigated. For each wing the torsion and bending elasticity is simulated by two torsional and longitudinal springs at its elastic axis. Furthermore, the connection winglet is simulated by a longitudinal spring. The aeroelastic governing equations are derived using Lagrange’s equations. Also, for aeroelastic loads simulation on the box wing, the Theodorsen aerodynamic model is used. The effects of various design parameters such as front and rear wing physical and geometrical properties, the connection winglet angle and stiffness, and aircraft altitude on the flutter of the system are investigated. Results show that the connection winglet stiffness and angle have significant influence on the box wing flutter boundary.

description: We have analyzed the radial distribution of old stars in a sample of 218 nearby face-on disks, using deep 3.6um images from the Spitzer Survey of Stellar Structure in Galaxies (S4G). In particular, we have studied the structural properties of those disks with a broken or down-bending profile. We find that, on average, disks with a genuine single exponential profile have a scale-length and a central surface brightness which are intermediate to those of the inner and outer components of a down-bending disk with the same total stellar mass. In the case of barred galaxies, the ratio between the break and the bar radii (Rbr/Rbar) depends strongly on the total stellar mass of the galaxy. For galaxies more massive than 10^10 Msun, the distribution is bimodal, peaking at Rbr/Rbar~2 and ~3.5. The first peak, which is the most populated one, is linked to the Outer Lindblad Resonance of the bar, whereas the second one is consistent with a dynamical coupling between the bar and the spiral pattern. For galaxies below 10^10 Msun, breaks are found up to ~10 Rbar, but we show that they could still be caused by resonances given the rising nature of rotation curves in these low-mass disks. While not ruling out star formation thresholds, our results imply that radial stellar migration induced by non-axysymmetric features can be responsible not only for those breaks at 2 Rbar, but also for many of those found at larger radii.

description: The geometrical point-wise satellite positions can be derived by GNSS analysis techniques. The different precise point positioning techniques based on GNSS observations will be designated as geometric orbit determination methods. In the geometrical determined LEO orbit, there is no connection between subsequent absolute positions, and consequently, no information about the velocity or even the acceleration (or in general kinematical information) of the satellite is available. To describe the time dependency of the motion of a satellite, it is necessary to provide a properly constructed function which consistently connects positions, velocities and accelerations. In this investigation, a new approach is presented based on approximation parameters, which have also a clearly defined relation to the dynamical model of the satellite's motion. To realize this, the kinematical orbit is not only a continuous approximation of the orbit as it is observed by GNSS observations; it is also a solution of Newton's equation of motion of the satellite. If the kinematical parameters are determined by a best fitting process based on the observations, then we perform a pure kinematical orbit determination. If constraints based on the dynamical force function model are used then the reduced kinematical orbit of a LEO is realized. In this case, we carry out a reduced kinematical orbit determination of a specific level, depending on the strength of the dynamical restrictions. The various possibilities of the reduced kinematical orbit determination with the corresponding results of CHAMP based on GNSS observations will be presented.

description: This paper looks at fuel consumption due to shaft power off-takes from the engine and the related increase in the aircraft’s fuel consumption. It presents a review and comparison of published and unpublished data on this kind of consumption. Insight is given into the effects caused by off-takes, looking at phenomena inside the engine when shaft power is extracted. The paper presents results from the TURBOMATCH engine simulation model, calibrated to real world engine data. Generic equations are derived for the calculation of fuel consumption due to shaft power extraction and values are presented for different flight altitudes and Mach numbers. Main result is the shaft power factor kP found to be in the order of 0.002 N/W for a typical cruise flight. This yields an amazingly high efficiency for power generation by shaft power extraction from a turbo fan engine of more than 70 %.

description: The optical response of a heavily doped quantum well, with two occupied subbands, has been investigated as a function of the electronic density. It is shown that the two optically active transitions are mutually coupled by dipole-dipole Coulomb interaction, which strongly renormalizes their absorption amplitude. In order to demonstrate this effect, we have measured a set of optical spectra on a device in which the electronic density can be tuned by the application of a gate voltage. Our results show that the absorption spectra can be correctly described only by taking into account the Coulomb coupling between the two transitions. As a consequence, the optical dipoles originating from intersubband transitions are not independent, but rather coupled oscillators with an adjustable strength.

description: We present VLA radio and Chandra X-ray observations of the merging galaxy cluster Abell 3411. For the cluster, we find an overall temperature of 6.4 keV and an X-ray luminosity of 2.8 x 10^{44} erg s^{-1} between 0.5 and 2.0 keV. The Chandra observation reveals the cluster to be undergoing a merger event. The VLA observations show the presence of large-scale diffuse emission in the central region of the cluster, which we classify as a 0.9 Mpc size radio halo. In addition, a complex region of diffuse, polarized emission is found in the southeastern outskirts of the cluster, along the projected merger axis of the system. We classify this region of diffuse emission as a radio relic. The total extent of this radio relic is 1.9 Mpc. For the combined emission in the cluster region, we find a radio spectral index of -1.0 \pm 0.1 between 74 MHz and 1.4 GHz. The morphology of the radio relic is peculiar, as the relic is broken up into five fragments. This suggests that the shock responsible for the relic has been broken up due to interaction with a large-scale galaxy filament connected to the cluster or other substructures in the ICM. Alternatively, the complex morphology reflects the presence of electrons in fossil radio bubbles that are re-accelerated by a shock.

subject: FOS: Physical sciences

description: This letter is the first to report that a super-resolution imaging beyond the Rayleigh limit can be achieved by using classical diffraction tomography (DT) extended with orbital angular momentum (OAM), termed as OAM based diffraction tomography (OAM-DT). It is well accepted that the orbital angular momentum (OAM) provides additional electromagnetic degrees of freedom. This concept has been widely applied in science and technology. In this letter we revisit the DT problem extended with OAM, demonstrate theoretically and numerically that there is no physical limits on imaging resolution in principle by the OAM-DT. This super-resolution OAM-DT imaging paradigm, has no requirement for evanescent fields, subtle focusing lens, complicated post-processing, etc., thus provides a new approach to realize the wavefield imaging of universal objects with sub-wavelength resolution.

description: The Galactic bulge shows a double red clump in sight lines with |b| > 5 deg and -3 deg < l < 4 deg. It is interpreted as a signature of an X-shaped structure seen almost edge-on. We measure the proper motions of the stars belonging to the closer and the further arm of the X-shaped structure. The intrinsic kinematic properties of the two arms are found by incorporating information taken from the luminosity function. At b = -5 deg we find that the proper motion difference between the two arms is a linear function of the Galactic longitude for -0.1 deg < l < 0.5 deg, which we interpret as a streaming motion of the stars within the X-shaped structure. Such a streaming motion has not previously been reported. The proper motion difference is constant for -0.8 deg < l < -0.1 deg, which gives us an estimate of bulge rotation speed of 87.9 +/- 8.2 km/s/kpc.

description: We consider stochastic discrete event dynamic systems that have time evolution represented with two-dimensional state vectors through a vector equation that is linear in terms of an idempotent semiring. The state transitions are governed by second-order random matrices that are assumed to be independent and identically distributed. The problem of interest is to evaluate the mean growth rate of state vector, which is also referred to as the mean cycle time of the system, under various assumptions on the matrix entries. We give an overview of early results including a solution for systems determined by matrices with independent entries having a common exponential distribution. It is shown how to extend the result to the cases when the entries have different exponential distributions and when some of the entries are replaced by zero. Finally, the mean cycle time is calculated for systems with matrices that have one random entry, whereas the other entries in the matrices can be arbitrary nonnegative and zero constants. The random entry is always assumed to have exponential distribution except for one case of a matrix with zero row when the particular form of the matrix makes it possible to obtain a solution that does not rely on exponential distribution assumptions.

Transition of a particle between adjacent optical traps: A study using catastrophe theory

description: In spite of the widespread use of optical tweezers as a quantitative tool to measure small forces, there exists no unambiguous and simple experimental method for either validating its theoretically predicted form or empirically parameterizing it over the entire range. This problem is addressed by studying the transition of a colloidal particle between two spatially separated optical traps. The transition as a function of the relative intensity of the traps and the separation between them reveals a formal resemblance to the `butterfly catastrophe' which also maps onto to phase transitions observed, for example in ferroelectrics, on a phenomenological level. The method has been used to experimentally determine the force-displacement curve for an optical trap over its entire range.

description: The method presented in this thesis allows for the calculation of the current and voltage spectra of a drive system for the steady state, while considering the influence of interactions between the system components. The signals are represented by their Fourier coefficients. Their relationships within the system are described by algebraic equations, which are generally nonlinear and they incorporate the coupling of the harmonic components. This ensures the consideration of interactions between the inverter, its feeding source and load, as well as its closed-loop control and pulse-width modulation. The models include the time-continuity of the physical quantities, the time-discretization of the control signals, and their respective conversion processes. As a result, this thesis provides a deeper understanding of the dependencies within a converter system and enables a calculation of the resulting spectra taking into account the aforementioned interactions, which are neglected in established frequency-domain models.
description: Die in dieser Arbeit vorgestellte Methodik ermöglicht die Berechnung der Strom- und Spannungsspektren eines Antriebssystems für den eingeschwungenen Zustand unter Berücksichtigung von Wechselwirkungen der Systemkomponenten. Die Darstellung der Signale mittels ihrer Fourier-Koeffizienten bildet die mathematische Grundlage. Die Beschreibung ihrer Systemverknüpfung erfolgt als algebraische Gleichungen, welche im Allgemeinen nichtlinear sind und die Verkopplung der spektralen Komponenten berücksichtigen. Dies ermöglicht die Beachtung der Interaktionen zwischen Wechselrichter, seiner Speisung und Last sowie seiner Regelung und Pulsdauermodulation. Dabei wird die Zeitkontinuität der physikalischen Größen, die Zeitdiskretisierung der Regelung und der entsprechende Umwandlungsprozess einbezogen. Damit trägt diese Arbeit zu einem tieferen Verständnis der Wechselwirkungen innerhalb eines Umrichtersystems bei und ermöglicht die Berechnung der entstehenden Spektren unter Berücksichtigung der Interaktionen, welche in gängigen Frequenzbereichsmodellen vernachlässigt werden.

description: We consider Fourier integral operators on non-compact manifolds and their applications, in particular in spectral theory. Fourier integral operators appear naturally as the solution operators of certain pseudodifferential evolution equations, such as the Schrödinger equation or the wave equation. For Euclidean space there are two important global pseudodifferential calculi: First there is the isotropic calculus, which contains the quantum harmonic oscillator, its inverse, and similar operators. We consider the solution operator to the dynamical Schrödinger equation with an isotropic pseudodifferential operator of order two and show how singularities and growth evolve with time. Moreover we show that for generic lower order perturbations of the harmonic oscillator the eigenvalues are more equally distributed then in the case of the unperturbed operator. The second important calculus, the scattering calculus, contains the Laplacian plus a bounded potential on asymptotically Euclidean manifolds. We define a class of geometric distributions that are related to the solution operators of the Klein-Gordon equation of quantum field theory and contain certain distributions that are appear in the scattering theory of the Laplacian. We show that these distributions have a symbol structure that admits an invariantly defined order and the existence of a principal symbol.

description: The efficacy of the Australian Disability Employment Services (DES) for autistic jobseekers has not been examined and is currently undergoing Government reform. To help inform the new DES strategy, we sought the views of: 24 autistic individuals; seven family members of autistic individuals, and; 46 DES employees. Data were collected using surveys and interviews. Data were analysed using Mann Whitney tests plus deductive thematic analysis based on Nicholas and colleagues’ ecosystems model. Participants highlighted a need to adapt existing policies to enhance flexibility of the DES model. There was participant consensus that DES staff require specific education and training to meet the needs of autistic people. Suggestions to inform the new model of DES for autistic people are made.
