Verbindungen mit eingeklebten Gewindestangen in Bauteilen aus Furnierschichtholz aus Buche
Creators: name: Meyer, Nico
Publisher: name: Karlsruhe
Year: 2016

description: Der Holzwerkstoff Furnierschichtholz aus Buche ist ein neuer Werkstoff im Bereich des Ingenieurholzbaus. Im Vergleich zu Brettschichtholz aus Fichte weist dieser eine bis zu dreifache Tragfähigkeit auf. Aus diesem Grund bietet sich die Konstruktion von Fachwerk-Bindern mit großen Spannweiten als Einsatzgebiet für diesen Werkstoff an. Mit großen Spannweiten gehen große zu übertragende Kräfte einher. Eingeklebte Gewindestangen bieten bereits die Möglichkeit, große Kräfte zwischen Holzbauteilen übertragen zu können. Dieser Beitrag stellt die Ergebnisse umfangreicher experimenteller Untersuchungen von faserparallel eingeklebten Gewindestangen in Furnierschichtholz aus Buche vor.

description: A generalized variant of the Calderón problem from electrical impedance tomography with partial data for anisotropic Lipschitz conductivities is considered in an arbitrary space dimension $n \geq 2$. The following two results are shown: (i) The selfadjoint Dirichlet operator associated with an elliptic differential expression on a bounded Lipschitz domain is determined uniquely up to unitary equivalence by the knowledge of the Dirichlet-to-Neumann map on an open subset of the boundary, and (ii) the Dirichlet operator can be reconstructed from the residuals of the Dirichlet-to-Neumann map on this subset.

description: Controlling the growth of piezoelectric lead zirconate titanate (Pb[ZrxTi1-x]O3 – PZT) thin-films is a key issue for their application in sensor and actuator devices. The pulsed laser deposition (PLD) process which is used in this work to grow PZT on platinized 150 mm silicon wafers can be easily modified by changing deposition parameters as the deposition pressure, deposition temperature, laser spot area on the target or laser pulse energy. In order to investigate the influence of these PLD parameters on the deposition rate and properties of the PZT thin-film as the leakage current density or the transverse piezoelectric coefficient e31,f, statistical Design of Experiment methods were applied. Empirical models could be derived, describing the thin-film properties as function of the deposition parameters. It is observed that not only the PZT deposition parameters but also the parameters which are modified for the deposition of the LaNiO3 (LNO) template need to be controlled carefully. The parameters with the highest effect on the e31,f are shown to be the combination of deposition pressure and deposition temperature of the PZT layer, where either both high or low values lead to good PZT properties.

description: We use a particle tagging technique to dynamically populate the N-body Via Lactea II high-resolution simulation with stars. The method is calibrated using the observed luminosity function of Milky Way satellites and the concentration of their stellar populations, and self-consistently follows the accretion and disruption of progenitor dwarfs and the build-up of the stellar halo in a cosmological "live host". Simple prescriptions for assigning stellar populations to collisionless particles are able to reproduce many properties of the observed Milky Way halo and its surviving dwarf satellites, like velocity dispersions, sizes, brightness profiles, metallicities, and spatial distribution. Our model predicts the existence of approximately 1,850 subhalos harboring "extremely faint" satellites (with mass-to-light ratios >5,000) lying beyond the Sloan Digital Sky Survey detection threshold. Of these, about 20 are "first galaxies", i.e. satellites that formed a stellar mass above 10 Msun before redshift 9. The ten most luminous satellites (L> 1e6 Lsun) in the simulation are hosted by subhalos with peak circular velocities today in the range V_max=10-40 km/s that have shed between 80% and 99% of their dark mass after being accreted at redshifts 1.7< z <4.6. The satellite maximum circular velocity and stellar line-of-sight velocity dispersion today follow the relation V_max=2.2 sigma_los. We apply a standard mass estimation algorithm based on Jeans modelling of the line-of-sight velocity dispersion profiles to the simulated dwarf spheroidals, and test the accuracy of this technique. The inner (within 300 pc) mass-luminosity relation for currently detectable satellites is nearly flat in our model, in qualitative agreement with the "common mass scale" found in Milky Way dwarfs. We do, however, predict a weak, but significant positive correlation for these objects: M_300 ~L^{0.088 \pm 0.024}.

description: Technological innovation and consequential decentralisation are driving forces in the ongoing evolution and increasing openness of digital infrastructures and services. One of the most discussed and allegedly disruptive innovations is the distributed database technology referred to as blockchain. Although it is still in its technological infancy, experimental adoption and customization seem to be in full progress in various potential fields of application ranging from decentralized grids for computation and storage to global financial services. However, the technology and its path of development still entail a lot of common unknowns for practitioners and researchers alike. Especially regarding the question how the technology could amend or be incorporated into the existing landscape of digital services, processes and infrastructures. Hence, in this article we develop an ontology that (1) clearly delineates common terminology, core concepts and components, their relationships as well as innovative features of blockchain technology. It further (2) connects these insights with implications for relevant types of digital market models. Our framework is of high theoretical and practical value as it provides researchers and practitioners a common basis for communication and means for guided analysis of blockchain applicability.

description: For the very first time, the following article traces the founding motives, structures and developments
of the Austrian Association for Librarianship (Österreichischer Verein für Bibliothekswesen,
ÖVB), from its founding in 1896 to its liquidation in May 1919. Through the establishment
of what became the oldest library association in continental Europe, librarians tried to
address library-policy matters and education-policy targets. At the same time, the association
tried to include as many bibliophile-minded parties as possible for the whole Habsburg empire
as well as to support the development and reassessment of librarianship overall. The association
can be seen as the predecessor of the Association of Austrian Librarians (Vereinigung Österreichischer
Bibliothekarinnen und Bibliothekare, VÖB), founded in 1946. The article is based
on an analysis of archival materials, especially those in the association’s archive.

description: We study the possibility of gauging the Standard Model flavor group. Anomaly cancellation leads to the addition of fermions whose mass is inversely proportional to the known fermion masses. In this case all flavor violating effects turn out to be controlled roughly by the Standard Model Yukawa, suppressing transitions for the light generations. Due to the inverted hierarchy the scale of new gauge flavor bosons could be as low as the electroweak scale without violating any existing bound but accessible at the Tevatron and the LHC. The mechanism of flavor protection potentially provides an alternative to Minimal Flavor Violation, with flavor violating effects suppressed by hierarchy of scales rather than couplings.

description: The spectral properties of a singular left-definite Sturm-Liouville operator $JA$ are investigated and described via the properties of the corresponding right-definite selfadjoint counterpart $A$ which is obtained by substituting the indefinite weight function by its absolute value. The spectrum of the $J$-selfadjoint operator $JA$ is real and it follows that an interval $(a,b)\subset\mathbb R^+$ is a gap in the essential spectrum of $A$ if and only if both intervals $(-b,-a)$ and $(a,b)$ are gaps in the essential spectrum of the $J$-selfadjoint operator $JA$. As one of the main results it is shown that the number of eigenvalues of $JA$ in $(-b,-a) \cup (a,b)$ differs at most by three of the number of eigenvalues of $A$ in the gap $(a,b)$; as a byproduct results on the accumulation of eigenvalues of singular left-definite Sturm-Liouville operators are obtained. Furthermore, left-definite problems with symmetric and periodic coefficients are treated, and several examples are included to illustrate the general results.

description: In diesem Beitrag werden die Wechselwirkungen zwischen dem schweizerischen Strommarkt und denen der Nachbarländer mit Hilfe von Korrelations- und Regressionsanalysen untersucht. Der Fokus wird dabei auf den Einfluss von fundamentalen Faktoren, die aus den Nachbarländern resultieren, auf den schweizerischen Strompreis gelegt.
Die Analysen zeigen, dass der schweizerische Strompreis im Sommer stärker mit dem deutschen Strompreis korreliert und die Auswirkungen der deutschen erneuerbaren Energien im Sommer eher signifikant sind. Die Studie zeigt jedoch auch, dass der Einfluss der Gaspreise und der Stromlast einen deutlich stärkeren Einfluss auf die Preise haben. Insbesondere eine hohe Last in der Schweiz und in den Nachbarländer Frankreich und Italien treiben die schweizerischen Preise im Winter in die Höhe, während in den letzten vier Jahren die Strompreise im Durchschnitt aufgrund der gefallenen Brennstoff- und CO2-Preise stark gefallen sind.

description: We report on the first systematic study of spin transport in bilayer graphene (BLG) as a function of mobility, minimum conductivity, charge density and temperature. The spin relaxation time $τ_s$ scales inversely with the mobility $μ$ of BLG samples both at room temperature and at low temperature. This indicates the importance of D'yakonov - Perel' spin scattering in BLG. Spin relaxation times of up to 2 ns are observed in samples with the lowest mobility. These times are an order of magnitude longer than any values previously reported for single layer graphene (SLG). We discuss the role of intrinsic and extrinsic factors that could lead to the dominance of D'yakonov-Perel' spin scattering in BLG. In comparison to SLG, significant changes in the density dependence of $τ_s$ are observed as a function of temperature.

We study analytically the perturbation of the dual gravity theory to calculate the superconducting coherence length $ξ$ of the $d$-wave holographic superconductor near the superconducting phase transition point. The superconducting coherence length $ξ$ divergents as $(1-T/T_c)^{-1/2}$ near the critical temperature $T_c$. We also obtain the magnetic penetration depth $λ\propto(T_c-T)^{-1/2}$ by adding a small external homogeneous magnetic field. The results agree with the $s$-wave and $p$-wave models, which are also the same as the Ginzburg-Landau theory.

description: A few exactly solvable interacting quantum many-body problems with impurities were previously reported to exhibit unusual features such as non-localization and absence of backscattering. In this work we consider the use of these integrable impurities as boundary conditions in the framework of linear transport problems. We first show that such impurities enhance the density of states at the Fermi surface, thus increasing the effective system size. The study of the real time-dynamics of a wave packet sent through a series of them inserted in both non-interacting and interacting leads then indicates that these impurities are transparent and do not add artefacts to the measurement of transport properties. We finally apply these new boundary conditions to study the conductance of an interacting scatterer using the embedding method.

description: We investigate the pp --> pp e+e- and quasifree pn --> pn e+e- reactions within an effective Lagrangian model at the laboratory kinetic energy of 1.25 GeV for which experimental data have recently been reported by the HADES Collaboration. The model uses a meson-exchange approximation to describe the initial nucleon-nucleon (NN) scattering. Contributions to the reaction amplitudes are included from the NN bremsstrahlung as well as from the excitation, propagation and radiative decay of the Delta(1230) isobar state. It is found that the HADES data on the e+e- invariant mass distribution in the pp --> pp e+e- reaction are reproduced excellently by our model where the Delta isobar term dominates the spectrum. However, the quasifree pn --> pn e+e- cross sections are underpredicted in the invariant mass region of 0.40 - 0.55 GeV/c^2 even after including contributions of the eta Dalitz decay and the subthreshold production and decay of the rho^0 meson via the baryonic resonance N*(1520). In the case of the quasifree pn --> pn e+e- reaction, a strong sensitivity to the pion electromagnetic form factor is observed which helps to bring the calculated cross sections closer to the data in the higher dilepton mass region.

the admission of Austrian librarians to the Association of German Librarians (Verein Deutscher
Bibliothekare) in 1920 and the association with German librarianship until 1945. The establishment
of a section within the union functioning as a successor to the ÖVB and its acting representatives
will also be discussed here. This small group of exclusively academically trained librarians
was part of the union of academic civil servants. Its officials were embedded in the
networks and structures of German nationalist and Christian social organisations and in the
unions dominated by those parties. Attention is also be given to the consequences of austerity
and stuff cuts in librarianship and the rise of National Library in Vienna under the leadership
of Josef Bick until 1938.

description: We investigate the reconstruction capabilities of Dark Matter mass and spin-independent cross-section from future ton-scale direct detection experiments using germanium, xenon or argon as targets. Adopting realistic values for the exposure, energy threshold and resolution of Dark Matter experiments which will come online within 5 to 10 years, the degree of complementarity between different targets is quantified. We investigate how the uncertainty in the astrophysical parameters controlling the local Dark Matter density and velocity distribution affects the reconstruction. For a 50 GeV WIMP, astrophysical uncertainties degrade the accuracy in the mass reconstruction by up to a factor of $\sim 4$ for xenon and germanium, compared to the case when astrophysical quantities are fixed. However, combination of argon, germanium and xenon data increases the constraining power by a factor of $\sim 2$ compared to germanium or xenon alone. We show that future direct detection experiments can achieve self-calibration of some astrophysical parameters, and they will be able to constrain the WIMP mass with only very weak external astrophysical constraints.

description: We analyze quantization of noncommutative chiral electrodynamics in the enveloping algebra formalism in linear order in noncommutativity parameter $θ$. Calculations show that divergences exist and cannot be removed by ordinary renormalization, however they can be removed by the Seiberg-Witten redefinition of fields. Performing the redefinitions explicitly, we obtain renormalizable lagrangian and discuss the influence of noncommutativity on field propagation. Noncommutativity affects the propagation of chiral fermions only: half of the fermionic modes become massive and birefringent.

We determine M[h_b(1P)]=(9898.3+/-1.1+1.0-1.1) MeV/c^2 and M[h_b(2P)]=(10259.8+/-0.6+1.4-1.0) MeV/c^2,which correspond to P-wave hyperfine splittings Delta(M_HF) = (+1.6+/-1.5) MeV/c^2 and (+0.5+1.6-1.2) MeV/c^2, respectively. The h_b(1P) and h_b(2P) are observed with significances of 5.5sigma and 11.2sigma, respectively. We also report measurements of the cross sections for e+e- \rightarrow h_b(nP)pi+pi- relative to that for e+e- --> Upsilon(2S)pi+pi-.

description: With the Sturm-Liouville analytical and numerical methods, we investigate the behaviors of the holographic superconductors by introducing a complex charged scalar field coupled with a Power-Maxwell field in the background of $d$-dimensional Schwarzschild AdS black hole. We note that the Power-Maxwell field takes the special asymptotical solution near boundary which is different from all known cases. We find that the larger power parameter $q$ for the Power-Maxwell field makes it harder for the scalar hair to be condensated. We also find that, for different $q$, the critical exponent of the system is still 1/2, which seems to be an universal property for various nonlinear electrodynamics if the scalar field takes the form of this paper.

RQM description of PS meson form factors, constraints from space-time translations, and underlying dynamics

description: The role of Poincaré covariant space-time translations is investigated in the case of the pseudoscalar-meson charge form factors. It is shown that this role extends beyond the standard energy-momentum conservation, which is accounted for in all relativistic quantum mechanics calculations. It implies constraints that have been largely ignored until now but should be fulfilled to ensure the full Poincaré covariance. The violation of these constraints, which is more or less important depending on the form of relativistic quantum mechanics that is employed, points to the validity of using a single-particle current, which is generally assumed in calculations of form factors. In short, these constraints concern the relation of the momentum transferred to the constituents to the one transferred to the system. How to account for the related constraints, as well as restoring the equivalence of different relativistic quantum mechanics approaches in estimating form factors, is discussed. Some conclusions relative to the underlying dynamics are given in the pion case.

description: We develop a holographic (bottom-up) gravity model for QCD to understand the connection between the peak in the trace anomaly and the magnitude of heavy quark energy loss in a strongly-coupled plasma. The potential of the scalar field on the gravity side is constructed to reproduce some properties of QCD at finite temperature and its parameters are constrained by fitting lattice gauge theory results. The energy loss of heavy quarks (as predicted by the holographic model) is found to be strongly sensitive to the medium properties.

description: We report measurements and analysis of magnetization, resistivity and thermopower of polycrystalline samples of the perovskite-type Co/Rh oxide La$_{0.8}$Sr$_{0.2}$Co$_{1-x}$Rh$_x$O$_{3-δ}$. This system constitutes a solid solution for a full range of $x$,in which the crystal structure changes from rhombohedral to orthorhombic symmetry with increasing Rh content $x$. The magnetization data reveal that the magnetic ground state immediately changes upon Rh substitution from ferromagnetic to paramagnetic with increasing $x$ near 0.25, which is close to the structural phase boundary. We find that one substituted Rh ion diminishes the saturation moment by 9 $μ_B$, which implies that one Rh$^{3+}$ ion makes a few magnetic Co$^{3+}$ ions nonmagnetic (the low spin state), and causes disorder in the spin state and the highest occupied orbital. In this disordered composition ($0.05\le x \le 0.75$), we find that the thermopower is anomalously enhanced below 50 K. In particular, the thermopower of $x$=0.5 is larger by a factor of 10 than those of $x$=0 and 1, and the temperature coefficient reaches 4 $μ$V/K$^2$ which is as large as that of heavy-fermion materials such as CeRu$_2$Si$_2$.

description: Understanding how computing infrastructure decisions influence overall performance and cost can be very difficult. Simulation techniques are an important tool to help analyse and evaluate different infrastructure configurations and deployment scenarios. As diversity of cloud computing resources is growing, the space of possible infrastructure configurations becomes larger and finding the best solution becomes harder. In our previous paper, we presented a framework to benchmark cloud resources to obtain objective and comparable results. Based on those results, our simulation framework allows to model applications and to estimate their performance. Compared to other infrastructure or cloud simulation tools our framework excels when it comes to
the simulation of network data flows.

description: We report results of air monitoring started due to the recent natural catastrophe on 11 March 2011 in Japan and the severe ensuing damage to the Fukushima Dai-ichi nuclear reactor complex. On 17-18 March 2011, we registered the first arrival of the airborne fission products 131-I, 132-I, 132-Te, 134-Cs, and 137-Cs in Seattle, WA, USA, by identifying their characteristic gamma rays using a germanium detector. We measured the evolution of the activities over a period of 23 days at the end of which the activities had mostly fallen below our detection limit. The highest detected activity amounted to 4.4 +/- 1.3 mBq/m^3 of 131-I on 19-20 March.

Integrability vs Supersymmetry: Poisson Structures of The Pohlmeyer Reduction

description: We construct recursively an infinite number of Poisson structures for the supersymmetric integrable hierarchy governing the Pohlmeyer reduction of superstring sigma models on the target spaces AdS_{n}\times S^n, n=2,3,5. These Poisson structures are all non-local and not relativistic except one, which is the canonical Poisson structure of the semi-symmetric space sine-Gordon model (SSSSG). We verify that the superposition of the first three Poisson structures corresponds to the canonical Poisson structure of the reduced sigma model. Using the recursion relations we construct commuting charges on the reduced sigma model out of those of the SSSSG model and in the process we explain the integrable origin of the Zukhovsky map and the twisted inner product used in the sigma model side. Then, we compute the complete Poisson superalgebra for the conserved Drinfeld-Sokolov supercharges associated to an exotic kind of extended non-local rigid 2d supersymmetry recently introduced in the SSSSG context. The superalgebra has a kink central charge which turns out to be a generalization to the SSSSG models of the well-known central extensions of the N=1 sine-Gordon and N=2 complex sine-Gordon model Poisson superalgebras computed from 2d superspace. The computation is done in two different ways concluding the proof of the existence of 2d supersymmetry in the reduced sigma model phase space under the boost invariant SSSSG Poisson structure.

Quantum property testing for bounded-degree graphs

description: We study quantum algorithms for testing bipartiteness and expansion of bounded-degree graphs. We give quantum algorithms that solve these problems in time O(N^(1/3)), beating the Omega(sqrt(N)) classical lower bound. For testing expansion, we also prove an Omega(N^(1/4)) quantum query lower bound, thus ruling out the possibility of an exponential quantum speedup. Our quantum algorithms follow from a combination of classical property testing techniques due to Goldreich and Ron, derandomization, and the quantum algorithm for element distinctness. The quantum lower bound is obtained by the polynomial method, using novel algebraic techniques and combinatorial analysis to accommodate the graph structure.
