description: How do local topological changes affect the global operation and stability of complex supply networks? Studying supply networks on various levels of abstraction, we demonstrate that and how adding new links may not only promote but also degrade stable operation of a network. Intriguingly, the resulting overloads may emerge remotely from where such a link is added, thus resulting in nonlocal failure. We link this counter-intuitive phenomenon to Braess' paradox originally discovered in traffic networks. We use elementary network topologies to explain its underlying mechanism for different types of supply networks and find that it generically occurs across these systems. As an important consequence, upgrading supply networks such as communication networks, biological supply networks or power grids requires particular care because even adding only single connections may destabilize normal network operation and induce disturbances remotely from the location of structural change and even global cascades of failures.

description: We present a model for dm-fiber bursts that is based on assuming fast sausage magnetoacoustic wave trains that propagate along a dense vertical filament or current sheet. Eight groups of dm-fiber bursts that were observed during solar flares were selected and analyzed by the wavelet analysis method. To model these fiber bursts we built a semi-empirical model. We also did magnetohydrodynamic simulations of a propagation of the magnetoacoustic wave train in a vertical and gravitationally stratified current sheet. In the wavelet spectra of the fiber bursts computed at different radio frequencies we found the wavelet tadpoles, whose head maxima have the same frequency drift as the drift of fiber bursts. It indicates that the drift of these fiber bursts can be explained by the propagating fast sausage magnetoacoustic wave train. Using new semi-empirical and magnetohydrodynamic models with a simple radio emission model we generated the artificial radio spectra of the fiber bursts, which are similar to the observed ones.

description: Combined solar and heat pump systems have a large potential to reduce CO2 and other emissions from the sector of domestic hot water preparation and space heating. Subtask C of the IEA SHC Task 44 / HPP Annex 38 deals with modeling and simulation of these systems. A review of component models for the simulation of combined solar and heat pump heating systems has been carried out with a special focus on the particularities of the combination of solar thermal collectors with heat pumps. Some of these particularities are effects of water vapor condensation on the surface of collector absorbers operated below the dew point, refrigeration cycles using more than one heat exchanger for the evaporator in order to use solar heat in addition to a conventional heat source, the effect of higher source temperature for the heat pump when solar heat is used, or the regeneration of ground heat sources with heat from solar collectors.

description: Magnetocaloric effect in Mn4FeGe3-xSix compounds has been studied by dc magnetization measurements. For the parent compound Mn4FeGe3, the paramagnetic to ferromagnetic transition temperature TC is above room temperature (320 K), which initially remains constant for small Si substitution at the Ge site and then decreases marginally with an increase in Si concentration. A large change in magnetic entropy at the TC, under a magnetic field variation of 50 kOe, with typical values of 5.9, 6.5, 5.9 and 4.4 J kg-1 K-1 for x = 0, 0.2, 0.6, and 1 samples, respectively, along with a broad operating temperature range and a negligible hysteresis make Mn4FeGe3-xSix series a promising candidate for magnetic refrigerant material around room temperature. Mn4FeGe3-xSix series is found to undergo a second-order magnetic phase transition. The field dependence of the magnetic entropy change has been brought out and implemented it to deduce the critical exponents. The critical behavior study shows that the magnetic interactions for x = 0 and 0.2 samples have two different behaviors below and above TC. Below TC, it follows the mean field theory with long-range magnetic interaction and above TC it follows the Heisenberg three-dimensional model with short-range or local magnetic interaction. The magnetic exchange interactions for the x = 0.6 and 1 samples follow the mean-field theory.

description: Different concepts of solar assisted heat pump systems with ground heat exchanger are simulated according to IEA SHC Task44/HPP Annex38 reference conditions. Two aspects of the concepts are investigated using TRNSYS simulations. First, the solar impact on system efficiency is assessed by the seasonal performance factor. Second, the solar impact on the possible shortening of the ground heat exchanger is evaluated by the minimum temperature at the ground heat exchanger inlet. The simulation results reveal diverging optimums for the concepts. The direct use of solar energy clearly achieves the best effect on the efficiency improvement. A simple domestic hot water system reaches a seasonal performance factor of 4.5 and solar combi-systems seasonal performance factors up to 6. In contrast, the use of solar energy on the cold side of the heat pump achieves the best effects on the shortening of the ground heat exchanger of up to 20%. Two highly sensitive influences are investigated with the developed transient system model. First, the minimum allowed heat source temperature is varied. Here 1 K equals a variation of 0.25 in the seasonal performance or of around 10% ground heat exchanger length. Second, the ground heat exchanger model is simulated without and with a pre-pipe that improves the transient model behavior. The influence of this pre-pipe on the SPF is small for conventionally designed ground heat exchangers, but of around 2 K for the minimum inlet temperature. Therefore, the dynamic model quality reveals potential to reduce the size of the ground heat exchanger corresponding to investment costs.

description: Security flaws in software applications today has been attributed mostly to design flaws. With limited budget and time to release software into the market, many developers often consider security as an afterthought. Previous research shows that integrating security into software applications at a later stage of software development lifecycle (SDLC) has been found to be more costly than when it is integrated during the early stages. To assist in the integration of security early in the SDLC stages, a new approach for assessing security during the design phase by neural network is investigated in this paper. Our findings show that by training a back propagation neural network to identify attack patterns, possible attacks can be identified from design scenarios presented to it. The result of performance of the neural network is presented in this paper.

description: A method is explained through which a pointwise accurate approximation to the pion's valence-quark distribution amplitude (PDA) may be obtained from a limited number of moments. In connection with the single nontrivial moment accessible in contemporary simulations of lattice-regularised quantum chromodynamics (QCD), the method yields a PDA that is a broad concave function whose pointwise form agrees with that predicted by Dyson-Schwinger equation analyses of the pion. Under leading-order evolution, the PDA remains broad to energy scales in excess of 100 GeV, a feature which signals persistence of the influence of dynamical chiral symmetry breaking. Consequently, the asymptotic distribution, ϕ_π^asy(x), is a poor approximation to the pion's PDA at all such scales that are either currently accessible or foreseeable in experiments on pion elastic and transition form factors. Thus, related expectations based on ϕ_π^asy(x) should be revised.

description: This paper presents a new flat plate collector technology based on heat pipes. The use of heat pipes can lead to several advantages over direct flow collectors: A simple hydraulic interconnection, an inherently limited stagnation temperature and substitution of copper. This flat plate collector prototype with aluminum heat pipes features all three aspects in one collector. The paper outlines the theoretical modeling approaches and presents the construction of the collector as well as detailed results of measurements of the collector performance. By use of specially designed heat pipes the heat transfer is limited at higher temperatures, which leads to a maximum stagnation temperature of 140°C at the manifold of the collector, thus preventing damages to the solar circuit fluid and solar components. Therefore, cost savings regarding the collector by substituting copper with aluminum and cost savings regarding the solar system due to lowered stagnation temperatures can be achieved.

description: We study the emergence of many-body correlations in the stationary state of continuously-driven, strongly-interacting dissipative system. Specifically, we examine resonant optical excitations of Rydberg states of atoms interacting via long-range dipole-dipole and van der Waals potentials employing exact numerical solutions of the density matrix equations and Monte-Carlo simulations. Collection of atoms within a blockade distance form a "superatom" that can accommodate at most one Rydberg excitation. The superatom excitation probability saturates to 1/2 for coherently driven atoms, but is significantly higher for incoherent driving, approaching unity as the number of atoms increases. In the steady state of uniformly-driven, extended one-dimensional system, the saturation of superatoms leads to quasi-crystallization of Rydberg excitations whose correlations exhibit damped spatial oscillations. The behavior of the system under the van der Waals interaction potential can be approximated by an analytically soluble model based on a "hard-rod" interatomic potential.

description: A new concept for solar active houses is presented within this paper. In contrast to existing solar house solutions, the solar collector heat gains are distributed in a temperature-optimized way to three different heat sinks - a significantly smaller storage tank, concrete floor elements directly fed by the solar circuit and a ground heat exchanger which also serves as the heat source of a heat pump, which is the backup heater. This new layout should reduce the today's usual extra system costs of solar houses by about 25%. System simulations prove the functionality of the concept and show even higher solar fractions and energy savings as simulated for the existing solar active house concept. One of the main components in the new concept is the controller which has to decide which heat sink will be charged. A control strategy was developed which evaluates the potential outputs of the collector operating to each heat sink. Simulations allow determining the optimal control parameters for this approach. While the thermal activation is able to compensate the decreasing solar input to the smaller storage tank, the effects of the regeneration of the ground heat exchanger are significantly smaller. However, the regeneration avoids a long-term temperature decrease in the ground and may allow a reduction of the heat exchanger area.

description: In topology optimization, the design parameter with no contribution to the objective function vanishes. This causes the stiffness matrix to become singular. We show that a local optimal solution is obtained by Conjugate Residual Method and Conjugate Gradient Method even if the stiffness matrix becomes singular. We prove that CGMconverges to a local optimal solution in that case. Computer simulation shows that CGM gives the same solutions obtained by CRM in case of a cantilever beam problem.

description: The formation of cracks in single crystal (SX) turbine blades is a common problem for aero-engines. To repair cracks, which are located under the tip-area, a new method is to clad with single-crystal-technology. This technology use multi-layer cladding to replace the single crystal material. To regenerate cracked material it is necessary to remove the crack affected material. The used notch geometries to remove the crackaffected area must be weldable and also permit the material solidification in the same oriented plane as the original microstructure. To solidify in the original structure a thermal gradient has to be introduced in order to guide the grain growth. This required gradient can be established by inductive heating. To reduce the thermal effected zone, a laser source is used. In addition, it is also an efficient process to fill the notch. Also the small local heat input and controlled material supply support the epitaxial growth. However, there are requirements to achieve a SX structure without cracks and pores. Current achievements and further challenges are presented in this paper.

description: The degree of crosslinking of ethylene vinyl acetate (EVA) is a decisive factor for the photovoltaic (PV) modules reliability. Numerous chemical or physical methods may be applied to determine the extent of crosslinking reaction in the EVA material. The usual and most accurate ones are destructive as they require a sample of material from the module. In this work we present a contactless and non-destructive method for monitoring the crosslinking process of EVA based on fluorescence spectroscopy. We show the correlation of fluorescence emission intensity of EVA when submitted to UV light with its curing grade determined by a rheological method. This approach is of interest for in-line monitoring of the crosslinking during the lamination step and for quality control after production. © 2014 The Authors. Published by Elsevier Ltd.

description: For simple digital circuits, conventional method of designing circuits can easily be applied. But for complex digital circuits, the conventional method of designing circuits is not fruitfully applicable because it is time-consuming. On the contrary, Genetic Programming is used mostly for automatic program generation. The modern approach for designing Arithmetic circuits, commonly digital circuits, is based on Graphs. This graph-based evolutionary design of arithmetic circuits is a method of optimized designing of arithmetic circuits. In this paper, a new technique for evolutionary design of digital circuits is proposed using Genetic Programming (GP) with Subtree Mutation in place of Graph-based design. The results obtained using this technique demonstrates the potential capability of genetic programming in digital circuit design with limited computer algorithms. The proposed technique, helps to simplify and speed up the process of designing digital circuits, discovers a variation in the field of digital circuit design where optimized digital circuits can be successfully and effectively designed.

description: It was previously established that the critical staggered XXZ spin chain provides a lattice regularization of the black hole CFT. We reconsider the continuum limit of this spin chain with the exact method of non-linear integral equations (NLIEs), paying particular attention to the effects of a singular integration kernel. With the help of the NLIEs, we rederive the continuous black hole spectrum, but also numerically match the density of states of the spin chain with that of the CFT, which is a new result. Finally, we briefly discuss the integrable structure of the black hole CFT and the identification of its massive integrable perturbation on the lattice.

description: Background: Mothers with borderline personality disorder (BPD) often show altered emotional availability toward their own child and heightened stress vulnerability. The aims of the present study were (1) to examine total cortisol output in saliva during mother-child interaction in mothers with BPD and their children and (2) to test whether maternal nonhostility as a subscale of emotional availability mediates the relationship between maternal BPD and child total cortisol output. Methods: We investigated 16 mothers with BPD and 30 healthy control mothers (HC) and 29 children of mothers with BPD and 33 children of HC mothers. Children were between 5 and 12 years old. Salivary cortisol was collected prior to and twice after an episode of a 21-min standardized play situation between mother and child. Nonhostility was rated using the emotional availability scales. Analyses of covariance were computed to test for group differences in total cortisol output (measured with area under the curve with respect to ground). Pearson's correlation was calculated to test the association between maternal and child total cortisol output. To test the second question, a mediation analysis according to Preacher and Hayes was conducted. Results: Mothers with BPD and their children had lower total cortisol output. Maternal and child total cortisol output was significantly correlated. Contrary to our hypothesis, maternal nonhostility did not mediate the relationship between BPD and child total cortisol output. Conclusion: Results imply that the hormonal stress activity of mothers with BPD and their children is altered, which may reflect modified stress regulation and stress vulnerability in mother and child and may impact on mother-child interaction. The finding of a positive association between mother's and child total cortisol output could indicate an intergenerational transmission of these alterations.

description: In this paper, interdigitated back contacted silicon heterojunction (IBC-SHJ) solar cell results as well as two dimensional device simulations are presented. The simulation indicates that for the minority contact (emitter) the coverage of the metallisation should be nearly 100%, while this is less critical for the majority contact (BSF). We present experimental results for an IBC-SHJ solar cell with a metallisation fraction of 100% for the emitter and approximately 65% for the BSF, with a high fill factor of 77.7% and an independently confirmed energy conversion efficiency of 19.4%.

description: We use SENTAURUS DEVICE simulation to investigate the effect of "passivated emitter and rear cell" (PERC) and "passivated emitter and rear, totally-diffused" (PERT) device architecture on the solar cells' weak light performances. Injection-dependent carrier lifetimes can also strongly influence the fill factor and weak light performance of solar cells. To focus on the effect of the device architecture alone, we present here simulations with essentially injection independent carrier lifetimes. In our simulations we find that at 1/10 of AM 1.5G ("tenth of one sun") the standard industrial cell architecture with full-area BSF loses about 1.7% efficiency and the similar PERT cell structure loses 1.4% to 1.6%, depending on wafer quality. The PERC cells suffer only 1.2% to 1.5% loss of efficiency at 1/10 sun. The lower losses for PERC solar cells result from the fact that at lower illumination intensity the relatively high resistance of PERC cells is less significant. We furthermore find that only for PERC solar cells the optimum wafer doping concentration depends on the illumination intensity.

description: Aims: Projected rotational velocities (\vsini) have been estimated for 334 targets in the VLT-FLAMES Tarantula survey that do not manifest significant radial velocity variations and are not supergiants. They have spectral types from approximately O9.5 to B3. The estimates have been analysed to infer the underlying rotational velocity distribution, which is critical for understanding the evolution of massive stars. Methods: Projected rotational velocities were deduced from the Fourier transforms of spectral lines, with upper limits also being obtained from profile fitting. For the narrower lined stars, metal and non-diffuse helium lines were adopted, and for the broader lined stars, both non-diffuse and diffuse helium lines; the estimates obtained using the different sets of lines are in good agreement. The uncertainty in the mean estimates is typically 4% for most targets. The iterative deconvolution procedure of Lucy has been used to deduce the probability density distribution of the rotational velocities. Results: Projected rotational velocities range up to approximately 450 \kms and show a bi-modal structure. This is also present in the inferred rotational velocity distribution with 25% of the sample having $0\leq$\ve$\leq$100\,\kms and the high velocity component having \ve$\sim 250$\,\kms. There is no evidence from the spatial and radial velocity distributions of the two components that they represent either field and cluster populations or different episodes of star formation. Be-type stars have also been identified. Conclusions: The bi-modal rotational velocity distribution in our sample resembles that found for late-B and early-A type stars. While magnetic braking appears to be a possible mechanism for producing the low-velocity component, we can not rule out alternative explanations.

description: Der Einsatz von leistungselektronischen Schaltungen ist für den Betrieb von elektrischen Geräten notwendig. Diese Schaltungen verursachen elektromagnetische Störungen. Mit Hilfe von Filtern können die Störungen reduziert werden. Die resultierenden leitungsgebundenen Störungsarten lassen sich anhand von Filterschaltungen dämpfen. Um das Verhalten einer Filterschaltung ohne Messung darzustellen, kann mithilfe empirisch ermittelter Ersatzschaltbilder der einzelnen Bauteile die Impedanz der Schaltung simuliert werden. Für die Wahl der richtigen Bauelemente und Filter ist es in der EMV wichtig, die Ausbreitungsverhältnisse der geleiteten Störungen und das Frequenzverhalten der einzelnen Bestandsteile zu kennen.. In diesem Beitrag wird ein Verfahren vorgestellt, mit dem es möglich ist, die Ersatzparameter der einzelnen Bauteile und die daraus resultierende Impedanz einer Filterschaltung ohne aufwendige Messungen zu bestimmen. Mithilfe der Software "PSpice" ist es möglich die einzelnen Ersatzschaltbilder der Bauelemente im Programm zu implementieren und deren Frequenzverhalten zu simulieren. Für den Entwurf einer Filterschaltung sollten zunächst die Impedanzen der einzelnen Bauteile aus dem Ergebnis der Simulation mit den Angaben des Herstellers verglichen werden. Durch die Verknüpfung der Ersatzschaltbilder ist es möglich, das Verhalten einer kompletten Schaltung zu simulieren. Um die Anwendbarkeit der vorgestellten Methode für beliebige Schaltungen zu prüfen, wurden mehrstufige Filter gemessen und simuliert. Abhängig von den elektrischen Eigenschaften der Bauelemente lässt sich die Gesamtimpedanz der Schaltung variieren und auf das Störspektrum anpassen.

description: This paper studies steady-state traffic flow on a ring road with up- and down- slopes using a semi-discrete model. By exploiting the relations between the semi-discrete and the continuum models, a steady-state solution is uniquely determined for a given total number of vehicles on the ring road. The solution is exact and always stable with respect to the first-order continuum model, whereas it is a good approximation with respect to the semi-discrete model provided that the involved equilibrium constant states are linearly stable. In an otherwise case, the instability of one or more equilibria could trigger stop-and-go waves propagating in certain road sections or throughout the ring road. The indicated results are reasonable and thus physically significant for a better understanding of real traffic flow on an inhomogeneous road.

description: We consider the topologically nontrivial phase states and the corresponding topological defects in the SU(3) d-dimensional quantum chromodynamics (QCD). The homotopy groups for topological classes of such defects are calculated explicitly. We have shown that the three nontrivial groups are pi_3 SU(3)=Z, pi_5 SU(3)=Z, and pi_6 SU(3)=Z_6 if 3 < d < 6. The latter result means that we are dealing exactly with six topologically different phase states. The topological invariants for d=3,5,6 are described in detail.

description: Zur Modellierung von elektromagnetischen Bandfilterstrukturen wurde eine neue Netzwerkdarstellung vorgestellt. Sie erlaubt die Berechnung des Frequenzverhaltens im Bereich unterhalb der Bandlücke. Für die Bestimmung der Netzwerkelemente wurden einfache Formeln in geschlossener Form angegeben. Zur Berücksichtigung von Randeffekten wurden die Lösungen für Mikrostreifenleitungen für die betrachtete 3D-Geometrie erweitert. Das Netzwerkmodell erlaubt die direkte Einbettung der elektromagnetischen Bandfilterversorgungslagen in eine SPICE-basierte Systemsimulation. Die Validierung des Modells anhand von 3D-Vollwellensimulationen und Messungen zeigen eine sehr gute Übereinstimmung in dem praktisch interessierenden Frequenzbereich unterhalb der Bandlücke.

description: Cellulose is one of the most versatile substances in the world. Its immense variety of applications was in recent years complemented by interesting nanotechnological applications. The fabrication of complex cellulose-based materials asks for thorough understanding of the surface structure and its interactions with adsorbates. In this study we investigate several surface model systems of nanotechnological interest, which are obtained by reorganization of the cellulose-vacuum or cellulose-water interfaces of slabs of crystalline cellulose. To do this, we constructed supercells from crystallographic data, and then optimized the interface structures. From the bulk and surface systems we calculated structural properties such as unit cell parameters, dihedral conformation distributions, density profiles and hydrogen bonding. The results suggest that no overall geometrical restructuring occurs at the interface. However, the hydrogen bond network is strongly reconstructed, as is inferred from the dihedral conformations and hydrogen bond occurrences, although only within the first few layers. This holds for low index close packed structures as well as for high index loosely packed surfaces. Replacing the vacuum by ambient pressure water molecules we find less rearrangements of the cellulose surface, because the water allows formation of hydrogen bonds similar to those in the bulk phase. The water near the cellulose surface shows, however, strong structural changes. We observe reduced mobility of the water molecules, which corresponds to a cooling of water by about 30 degrees, in a slab that is about 10 Å thick. Although structuring and adsorption is observed on all surfaces, no actual penetration of water into the cellulose structure could be observed. This suggests that pure water is not sufficient to produce cellulose swelling at mesoscopic timescales.
