description: This article examines different paradigms of conversions to Christianity in regions of Africa prior to the advent of colonial modernity. Religious change, in general, connected converts and various intermediaries to resources and power within specific settings. Even though African cultures were oral, conversions generated the production of texts which became important print media and were at least partly responsible for prompting conversions elsewhere in the world. The first case study explains how mission initiatives along the so-called West African slave coast almost always resulted in failure between 1450 and 1850, but how these failed efforts figure as important halfway options which reveal fundamental mechanisms of conversion. The dynamics of interaction were different in the African Kingdom of Kongo, where conversions became intimately entwined in the consolidation of political power and where, subsequent to the adoption of Christianity, new understandings of power evolved. Last but not least, in South Africa, again, another paradigm of conversion developed within the nexus of conflict and settler violence. Contested narratives of Christianity and conversion emerged as settlers tried to keep Christianity as a religious resource to be shared among whites only.
On the evolution of irradiated turbulent clouds: A comparative study between modes of triggered star-formation

description: Here we examine the evolution of irradiated clouds using the Smoothed Particle Hydrodynamics ({\small SPH}) algorithm coupled with a ray-tracing scheme that calculates the position of the ionisation-front at each timestep. We present results from simulations performed for three choices of {\small IR}-flux spanning the range of fluxes emitted by a typical {\small B}-type star to a cluster of {\small OB}-type stars. The extent of photo-ablation, of course, depends on the strength of the incident flux and a strong flux of {\small IR} severely ablates a {\small MC}. Consequently, the first star-formation sites appear in the dense shocked layer along the edges of the irradiated cloud. Radiation-induced turbulence readily generates dense filamentary structure within the photo-ablated cloud although several new star-forming sites also appear in some of the densest regions at the junctions of these filaments. Prevalent physical conditions within a {\small MC} play a crucial role in determining the mode, i.e., filamentary as compared to isolated pockets, of star-formation, the timescale on which stars form and the distribution of stellar masses. The probability density functions ({\small PDF}s) derived for irradiated clouds in this study are intriguing due to their resemblance with those presented in a recent census of irradiated {\small MC}s. Furthermore, irrespective of the nature of turbulence, the protostellar mass-functions({\small MF}s) derived in this study follow a power-law distribution. When turbulence within the cloud is driven by a relatively strong flux of {\small IR} such as that emitted by a massive {\small O}-type star or a cluster of such stars, the {\small MF} approaches the canonical form due to Salpeter, and even turns-over for protostellar masses smaller than $\sim$0.2 M$_{\odot}$.

description: beta-YbAlB4 is a heavy fermion superconductor that exhibits a quantum criticality without tuning at zero field and under ambient pressure. We have succeeded in substituting Fe for Al in beta-YbAlB4 as well as the polymorphous compound alpha-YbAlB4, which in contrast has a heavy Fermi liquid ground state. Full structure determination by single crystal X-ray diffraction confirmed no change in crystal structure for both alpha- and beta-YbAlB4, in addition to volume contraction with Fe substitution. Our measurements of the magnetization and specific heat indicate that both alpha-YbAl0.93Fe0.07B4 and beta-YbAl0.94Fe0.06B4 exhibit a magnetic order, most likely of a canted antiferromagnetic type, at $7\sim 9$ K. The increase in the entropy as well as the decrease in the antiferromagnetic Weiss temperature with the Fe substitution in both systems indicates that the chemical pressure due to the Fe substitution suppresses the Kondo temperature and induces the magnetism.

description: The chapter aims to analyze the politics of grieving related to the massacres that occurred in the Mediterranean during forced migration by boats. The theoretical framework includes the concept of "grievability" by Judith Butler, as well as the concept of "differential inclusion" by Sandro Mezzadra and Brett Neilson. By drawing on a semiotic perspective, the author analyzes two case studies: the Kater I Rades, an Albanian boat that sank in the Strait of Otranto after colliding with an Italian military naval vessel in 1997, and the shipwrecks in Lampedusa on October 3 and 11, 2013.

description: Organizational ecology is commonly seen as a Darwinian research program that seeks to explain the diversity of organizational structures, properties and behaviors as the product of selection in past social environments in a similar manner as evolutionary biology seeks to explain the forms, properties and behaviors of organisms as consequences of selection in past natural environments. We argue that this explanatory strategy does not succeed because organizational ecology theory lacks an evolutionary mechanism that could be identified as the principal cause of organizational diversity. The "evolution" of organizational populations by means of selection, which organizational ecologists put forward as the mechanism responsible for the extant diversity of organizational forms, is not evolution in any proper sense, because organizational populations do not have what it takes to participate in evolutionary processes. This implies that organizational ecology is not a Darwinian research program and that it cannot explain organizational diversity. © 2009 SAGE Publications.

description: Recent experimental results based on the digital image correlation technique (U. Eitner, M. Köntges, R. Brendel, Solar Energy Mater. Solar Cells, 2010, 94, 1346-1351) show that the gap between solar cells embedded into a standard photovoltaic laminate varies with temperature. The variation of this gap is an important quantity to assess the integrity of the electric connection between solar cells when exposed to service conditions. In this paper, the thermo-elastic deformations in photovoltaic laminates are analytically investigated by developing different approximate models based on the multilayered beam theory. It is found that the temperature-dependent thermo-elastic properties of the encapsulating polymer layer are responsible for the deviation from linearity experimentally observed in the diagram relating the gap variation to the temperature. The contribution of the different material constituents to the homogenized elastic modulus and thermal expansion coefficient of the composite system is also properly quantified through the definition of weight factors of practical engineering use.

Finite Alphabet Iterative Decoders, Part II: Improved Guaranteed Error Correction of LDPC Codes via Iterative Decoder Diversity

description: Recently, we introduced a new class of finite alphabet iterative decoders (FAIDs) for low-density parity-check (LDPC) codes. These decoders are capable of surpassing belief propagation in the error floor region on the Binary Symmetric channel with much lower complexity. In this paper, we introduce a a novel scheme to further increase the guaranteed error correction capability from what is achievable by a FAID on column-weight-three LDPC codes. The proposed scheme uses a plurality of FAIDs which collectively correct more error patterns than a single FAID on a given code. The collection of FAIDs utilized by the scheme is judiciously chosen to ensure that individual decoders have different decoding dynamics and correct different error patterns. Consequently, they can collectively correct a diverse set of error patterns, which is referred to as decoder diversity. We provide a systematic method to generate the set of FAIDs for decoder diversity on a given code based on the knowledge of the most harmful trapping sets present in the code. Using the well-known column-weight-three $(155,64)$ Tanner code with $d_{min}$ = 20 as an example, we describe the method in detail and show that the guaranteed error correction capability can be significantly increased with decoder diversity.

description: Total cross sections for proton- and deuteron-induced-fission of 208Pb and 238U have been determined in the energy range between 500 MeV and 1 GeV. The experiment has been performed in inverse kinematics at GSI Darmstadt, facilitating the counting of the projectiles and the identification of the reaction products. High precision between 5 and 7 percent has been achieved by individually counting the beam particles and by registering both fission fragments in coincidence with high efficiency and full Z resolution. Fission was clearly distinguished from other reaction channels. The results were found to deviate by up to 30 percent from Prokofiev's systematics on total fission cross sections. There is good agreement with an elaborate experiment performed in direct kinematics.

description: In recent years, various elaborate visual methods have been introduced for carrying out empirically controlled sociological studies. However, in contrast to other sociological sub-fields, research on protest events or social movements rarely employs visual analytic procedures. In this article, a research sample of visual protest material is taken to show how applied visual methods can increase the outcome of protest or social movement research. This study highlights how visual analysis provides extra information for supporting or rejecting interpretations, thus demonstrating that visual methods are an important tool in the triangulation of empirical methods. © SAGE Publications 2011.

description: 6LoWPAN (IPv6 over IEEE 802.15.4) standardized by IEEE 802.15.4 provides IP communication capability for nodes in WSN. An adaptation layer is introduced above the MAC layer to achieve header compression, fragmentation and reassembly of IP packets. The location-based information is used to simplify the routing policy. This paper proposes an efficient location-based routing protocol, considering link quality and distance between nodes as the routing metric. The proposed Enhanced Location-based routing protocol (ELBRP) was simulated in NS2 version 2.32 and performance were analysed in terms of packet delivery ratio, throughput and average end-to-end delay. From the results obtained, it is found that the proposed ELBRP outperforms existing LOAD protocol.

description: Compact self-recirculating injection that bleeds air from the casing downstream of a rotor blade row and injects the air as a wall jet upstream of the same rotor blade row is experimentally studied after the elaborated design of its structure. The bleed ports, injection ports, and recirculating channels are circumferentially discrete and occupy only 38% of the circumference. Separate tip air injection and outlet bleed air are simultaneously selected for comparison with the self-recirculating injection. Results show that the compact self-recirculating injection can improve the most stall margin by 6.12% among all the three cases on the premise of no efficiency penalty and can also enhance the efficiency (maximum of 1%) for only 0.47% of the total injected momentum ratio recirculated near stall. The details of the flow field are obtained using a multihole probe, a time-resolved Kiel probe, and pressure transducers. The detailed comparative analysis of the characteristic flow in terms of tip leakage flow, blade load, rotor wake feature, and blockage indicates that the self-recirculating injection can postpone the occurrence of stalling in the proposed compressor through a coupling influencing mechanism. One mechanism is to weaken the self-induced unsteadiness of tip leakage flow and to delay the forward movement of the interface between the tip leakage flow and the main flow. The other mechanism is to unload the blade tip and to recover the rotor wake. All these responses can lead to improved stall margin in the self-recirculating injection. This study may be helpful to guide the design of self-recirculating injection in actual application. © Institution of Mechanical Engineers.
A computational toy model for shallow landslides: Molecular Dynamics approach

description: The aim of this paper is to propose a 2D computational algorithm for modeling of the trigger and the propagation of shallow landslides caused by rainfall. We used a Molecular Dynamics (MD) inspired model, similar to discrete element method (DEM), that is suitable to model granular material and to observe the trajectory of single particle, so to identify its dynamical properties. We consider that the triggering of shallow landslides is caused by the decrease of the static friction along the sliding surface due to water infiltration by rainfall. Thence the triggering is caused by two following conditions: (a) a threshold speed of the particles and (b) a condition on the static friction, between particles and slope surface, based on the Mohr-Coulomb failure criterion. The latter static condition is used in the geotechnical model to estimate the possibility of landslide triggering. Finally the interaction force between particles is defined trough a potential that, in the absence of experimental data, we have modeled as the Lennard-Jones 2-1 potential. In the model the viscosity is also introduced and for a large range of values of the model's parameters, we observe a characteristic velocity pattern, with acceleration increments, typical of real landslides. The results of simulations are quite promising: the energy and the time triggering distributions of local avalanches shows a power law distribution, analogous to the observed Gutenberg-Richter and Omori power law distributions for earthquakes. Finally it is possible to apply the method of the inverse surface displacement velocity [Fukuzono 1985] for predicting the failure time.

description: Observations of the X-ray pulsar 4U 2206+54, performed over a 15-year span, show its period, which is now 5555 \pm 9 s, to increase drastically. Such behavior of the pulsar can be hardly explained in the frame of traditional scenarios of spin evolution of compact stars. The observed spin-down rate of the neutron star in 4U 2206+54 proves to be in good agreement with the value expected within magnetic accretion scenario which takes into account that magnetic field of the accretion stream can under certain conditions affect its geometry and type of flow. The neutron star in this case accretes material from a dense gaseous slab with small angular momentum which is kept in equilibrium by the magnetic field of the flow itself. The magnetic accretion scenario can be realized in 4U 2206+54 provided the magnetic field strength on the surface of the optical counterpart to the neutron star is in excess of 70 G. The magnetic field strength on the surface of the neutron star in the frame of this scenario turns out to be 4 x 10^{12} G which is in accordance with estimates of this parameter from the analysis of X-ray spectra of the pulsar.

description: Mit der fortschreitenden Optimierung moderner Verbrennungsmotoren in Straßenfahrzeugen gewinnen alternative Systeme zur Effizienzsteigerung an Bedeutung. Dabei verspricht die Abgaswärmenutzung mittels eines Organic Rankine Cycles (ORC) ein signifikantes Potential zur Treibstoffeinsparung. Der Wirkungsgrad des ORCs ist stark vom Wirkungsgrad der Expansionsmaschine abhängig. Die These dieser Arbeit lautet: Axiale Turbinen eignen sich für den Einsatz in ethanolbetriebenen ORCs geringer Leistung und weisen durch eine variable Teilbeaufschlagung ein verbessertes Teillastverhalten auf. Eine thermodynamische Analyse bestätigt die Eignung von Ethanol als Kreislaufmedium für eine LKW-Anwendung. Es ergibt sich allerdings ein hohes Druckverhältnis von bis zu 49 bei geringen Massenströmen. Für einen effizienten Betrieb wurde eine Turbine entwickelt, die sich durch supersonische Schaufelkonturen und eine variable Teilbeaufschlagung zur Kennfelderweiterung auszeichnet. Die aerodynamische Bewertung der Turbine erfolgte mit CFD, die mit einem analytischen Ansatz zur Verlustberechnung durch Teilbeaufschlagung gekoppelt wurde. Mit diesem Ansatz wird eine Leistung der Turbine von 1,1 bis 18,5 kW bei einem Wirkungsgrad von bis zu 65,8% prognostiziert. Für die experimentelle Untersuchung der Turbine wurde eine getriebelose Generatoreinheit gefertigt. Durch Fertigungsabweichungen im Hals der Lavaldüsen kommt es zu einer Kennfeldverschiebung der Turbine zu höheren Massenströmen und Leistungen. Im Rahmen der experimentellen Untersuchung wurden 40% des Turbinenkennfelds vermessen. Dabei erzielte die Turbine eine Leistung von 1,8 bis 7,6 kW. Auf Basis dieser Kennfelder wurde mit einer Kreisprozesssimulation ein Treibstoffeinsparpotential von bis zu 4,5% ermittelt und das Potential zur Prozessverbesserung durch variable Teilbeaufschlagung bestätigt. Über einen breiten Kennfeldbereich zeigen die Turbinen einen charakteristischen Strömungszustand. Bei einem ausreichend hohen Turbinendruckverhältnis ist die Verteilung von Mach-Zahl und Druckverhältnis bezogen auf den Eintrittsdruck bis zum Rotoraustritt zwar drehzahlabhängig, aber unabhängig vom Eintritts- und Austrittsdruck. Eine Anpassung an den Turbinenaustrittsdruck erfolgt am Rotoraustritt durch eine supersonische Expansion, die bei Druckverhältnissen deutlich über dem Auslegungsdruck zu signifikanten Verlusten führt.

description: Top-down causation has been suggested to occur at all scales of biological organization as a mechanism for explaining the hierarchy of structure and causation in living systems. Here we propose that a transition from bottom-up to top-down causation -- mediated by a reversal in the flow of information from lower to higher levels of organization, to that from higher to lower levels of organization -- is a driving force for most major evolutionary transitions. We suggest that many major evolutionary transitions might therefore be marked by a transition in causal structure. We use logistic growth as a toy model for demonstrating how such a transition can drive the emergence of collective behavior in replicative systems. We then outline how this scenario may have played out in those major evolutionary transitions in which new, higher levels of organization emerged, and propose possible methods via which our hypothesis might be tested.

description: Safety is a key requirement in physical human- robot interaction. In particular, the influence of robot dynamic properties on human injury probability has to be understood well. Then, potential harm can be minimized already at an early stage of the robot design process. In this work, we propose the safety map concept, a map that captures the robot inherent safety properties and human injury occurrence in a unified way from both a global, and a task-dependent perspective. This makes it a novel, powerful, and convenient tool to quantitatively analyze the safety performance of a certain robot design. We elaborate the concept, describe how to process human and robot data towards the safety map representation and show how it can be integrated into the safety assessment and (automatic) robot design workflow.

description: Helle, weiße LEDs kommen zunehmend in Neuentwicklungen von Fahrzeugscheinwerfern als Ersatz für klassische Xenon- und Halogen-Lichtquellen zum Einsatz. Einen nächsten Schritt in dieser Entwicklung stellen Lichtquellen auf Basis von Laserdioden in Verbindung mit „Remote Phosphor“ (laseraktiviertem Leuchtstoff) zur Frequenzkonversion dar. Dieser Ansatz bietet insbesondere im Hinblick auf Leuchtdichte, Effizienz und Designflexibilität ein hohes Potenzial. In Verbindung mit Laserdioden können kleinere strahlformende Elemente zum Einsatz kommen, so dass neue Konzepte für adaptive Scheinwerfersysteme möglich werden. Zur Verbesserung der Fahrbahnausleuchtung wird das klassische Fernlicht in vielen Scheinwerfersystemen durch ein zusätzliches Lichtmodul ergänzt. Diese Funktion wird mit einer laserbasierten Lichtquelle platzsparend umgesetzt. Aufbauend auf Voruntersuchungen werden verschiedene Designvarianten präsentiert. Der Fokus wird hierbei auf die Umsetzung reflektorbasierter Lichtmodule gelegt, welche sowohl mit Hilfe konventioneller als auch generativer Fertigungsverfahren hergestellt werden. Die Konstruktion mit einem fernaktivierten Leuchtstoff ermöglicht dabei durch die Trennung von Lichterzeugung und Frequenzkonversion ein verbessertes Thermomanagement der Systeme. Die einzelnen Prototypen werden hinsichtlich ihrer lichttechnischen Parameter untersucht und verglichen. Der Einsatz im Fahrzeug wird durch Integration eines geeigneten Systems gezeigt und untersucht.

description: By means of nuclear spin-lattice relaxation rate 1/T1, we follow the spin dynamics as a function of the applied magnetic field in two gapped one-dimensional quantum antiferromagnets: the anisotropic spin-chain system NiCl2-4SC(NH2)2 and the spin-ladder system (C5H12N)2CuBr4. In both systems, spin excitations are confirmed to evolve from magnons in the gapped state to spinons in the gapples Tomonaga-Luttinger-liquid state. In between, 1/T1 exhibits a pronounced, continuous variation, which is shown to scale in accordance with quantum criticality. We extract the critical exponent for 1/T1, compare it to the theory, and show that this behavior is identical in both studied systems, thus demonstrating the universality of quantum critical behavior.

description: In this paper we consider scattering theory on manifolds with special cusp-like metric singularities of warped product type g=dx2+x−2ah, where a>0. These metrics form a natural subset in the class of metrics with warped product singularities and they can be thought of as interpolating between hyperbolic and cylindrical metrics. We prove that the resolvent of the Laplace operator acting on p-forms on such a manifold extends to a meromorphic function defined on the logarithmic cover of the complex plane with values in the bounded operators between weighted L2-spaces. This allows for a construction of generalized eigenforms for the Laplace operator as well as for a meromorphic continuation of the scattering matrix. We give a precise description of the asymptotic expansion of generalized eigenforms on the cusp and find that the scattering matrix satisfies a functional equation.

description: This research focuses on detection of unauthorized access to residential and commercial buildings when the residents are far away from the access gate of the house. The system is a simple and reliable touch activated security system and uses sensor technology to revolutionize the standards of living. The system provides a best solution to most of the problems faced by house owners in their daily life. Due to its simple electronic components nature, it is more adaptable and cost-effective. The system is divided into three units; the power supply unit which employs the use of both DC battery and mains supply to ensure constant power supply to the circuit, the trigger unit which is responsible for activating the alarm unit and designed to have much time and period and moderate sensitivity in order to reduce the rate of false alarm, and the alarm amplitude unit which main function is to produce amplitude alarm sound when triggered by the trigger unit with the aim of producing a large audible sound that can alert the entire neighborhood or scare an intruder away. The design of the system was achieved by considering some factors such as economy, availability of components and research materials, efficiency, compatibility and portability and also durability in the design process. The performance of the system after test met design specifications. This system works on the principle of touch sensor. The general operation of the system and performance is dependent on the presence of an intruder entering through the door and touching any part of the door. The overall system was constructed and tested and it work perfectly.

description: The sol–gel technique followed by conventional (TiO2-1) and hydrothermal (TiO2-2) thermal treatment was employed to prepare TiO2-based photocatalysts with distinct particle sizes and crystalline structures. The as prepared metal oxides were evaluated as photocatalysts for gaseous HCHO degradation, methanol, and dye oxidation reactions. Additionally, metallic platinum was deposited on the TiO2 surfaces and H2 evolution measurements were performed. The photocatalytic activities were rationalized in terms of morphologic parameters along with the electron/hole dynamics obtained from transient absorption spectroscopy (TAS). TiO2-2 exhibits smaller particle size, poorer crystallinity, and higher surface area than TiO2-1. Moreover the hydrothermal treatment leads to formation of the metastable brookite phase, while TiO2-1 exhibits only the anatase phase. TAS measurements show that the electron/hole recombination of TiO2-2 is faster than that of the latter. Despite that, TiO2-2 exhibits higher photonic efficiencies for photocatalytic oxidation reactions, which is attributed to its larger surface area that compensates for the decrease of the surface charge carrier concentration. For H2 evolution, it was found that the surface area has only a minor effect and the photocatalyst performance is controlled by the efficiency of the electron transfer to the platinum islands. This process is facilitated by the higher crystallinity of TiO2-1, which exhibits higher photonic efficiency for H2 evolution than that observed for TiO2-2. The results found here provide new insights into the correlations between thermal treatment conditions and photocatalytic activity and will be useful for the design of high performance photocatalysts.

description: In this Letter, we investigate the group delay of optical pulses through multilayer dielectric mirrors (MDM) combined with gravitational wave (GW). We find that the delay increases linearly with MDM length for the transmitted wave packet, whereas the Hartman effect disappears. Our study provides insight into the nature of both quantum tunnelling and GW.
