description: Today, the reduction of CO2 emissions is essential to meet global climate requirements. In this context, a reduction in vehicle weight is the most efficient way to reduce the fuel consumption of a passenger car. Magnesium combines relatively high strength with low weight and is therefore an interesting construction material for lightweight solutions. In numerical process design, it is essential to be aware of the forming capacity of a material. The common method to describe the failure behaviour is the use of forming limit curve (FLC). Stress-based models offer the advantage of a strain path consideration and an extension in the area of shearing and compression. In this paper a stress-based damage model, Modified Mohr-Coulomb (MMC), was parameterized by IFUM Butterfly-Tests for an AZ31 magnesium sheet alloy under consideration of elevated process temperatures. For this purpose, the tests were carried out at different stress states and temperatures using a specially designed testing device. In addition, forming limit curves were determined by Nakajima tests. Finally, both methods, MMC and FLC, were compared to an experimental deep-drawing test. This comparison showed that the MMC Model achieved significantly better results regarding the fracture prediction in this application case.

description: This thesis consists of two empirical chapters on product market competition and capital structure decisions. In Chapter II, we find that competitive threats are positively associated with the use of convertible debt financing as the possibility of conversion enhances financial flexibility. In Chapter III, we explore operating performance following new equity issues under the theoretical framework of Lyandres (2008), which predicts inferior operating performance of issuers relative to their rivals as SEOs translate into a larger decline in profitability for the former than for the latter. Our empirical results support the predictions in Lyandres (2008).

description: Aims: We aim to use the high spatial resolution of the Atacama Large Millimeter/submillimeter Array (ALMA) to map the flow pattern of molecular gas near DG Tau and its disk, a young stellar object driving a jet and a molecular outflow. Methods: We use observations from ALMA in the J = 2 - 1 transition of 12CO, 13CO, and C18O to study the Keplerian disk of DG Tau and outflows that may be related to the disk and the jet. Results: We find a new wind component flowing radially at a steep angle (~25 deg from the vertical) above the disk with a velocity of ~ 3.1 km/s. It continues the trend of decreasing velocity for increasing distance from the jet axis ("onion-like velocity structure"). Conclusions: The new component is located close to the protostellar disk surface and may be related to photoevaporative winds.

description: In this study the complexation of U(VI) with orthosilicic acid (H4SiO4) was investigated between pH 3.5 and 5 by combining electrospray ionization mass spectrometry (ESI-MS) and laser-induced luminescence spectroscopy. The ESI-MS experiments performed at a total silicon concentration of 5 · 10−3 M (exceeding the solubility of amorphous silica at both pH-values) revealed the formation of oligomeric sodium-silicates in addition to the UO2OSi(OH)3+ species. For the luminescence spectroscopic experiments (25 °C), the U(VI) concentration was fixed at 5 · 10−6 M, the silicon concentration was varied between 1.3 · 10−4–1.3 · 10−3 M (reducing the formation of silicon oligomers) and the ionic strength was kept constant at 0.2 M NaClO4. The results confirmed the formation of the aqueous UO2OSi(OH)3+ complex. The conditional complexation constant at 25 °C, log *β = −(0.31 ± 0.24), was extrapolated to infinite dilution using the Davies equation, which led to log *β0 = −(0.06 ± 0.24). Further experiments at different temperatures (1–25 °C) allowed the calculation of the molal enthalpy of reaction ΔrHm0 = 45.8 ± 22.5 kJ·mol−1 and molal entropy of reaction ΔrSm0 = 152.5 ± 78.8 J·K−1·mol−1 using the integrated van't Hoff equation, corroborating an endothermic and entropy driven complexation process.

description: We discuss the general operator product expansion of a non-forward unequal mass virtual compton scattering scattering amplitude. We find that the expansion now should be done in double moments with new moment variables. There are in the expansion new sets of leading twist operators which have overall derivatives, and they mix under renormalization. We compute the evolution kernels from which the anomalous dimensions for these operators can be extracted. We also obtain the lowest order Wilson Coefficients. In the high energy limit we find the explicit form of the dominant contributing anomalous dimensions and solve the resulting renormalization group equation. We find the same high energy behavior as indicated by the conventional double leading logarithmic analysis.

description: We investigate anharmonically coupled high- and low-frequency excitations in a planar lattice of adsorbed molecules interacting with phonons of a crystal. Dephasing of high-frequency local vibrations by low-frequency resonance modes is described in terms of temperature Green's function. The equations obtained are solved, first, with a small ratio of the anharmonic coupling coefficient for high- and low-frequency modes to the resonance width, and second, in the low-temperature limit. High-frequency spectral line positions and widths depend on dispersion laws and resonance mode lifetimes. It is shown that lateral interactions of low-frequency modes of adsorbed molecules can lead to a significant narrowing of high-frequency spectral lines, which is consistent with experimental data.

description: We apply theoretical spin-down models of magnetospheric evolution and magnetic field decay to simulate the possible evolution of PSR J0250+5854, which is the slowest-spinning radio pulsar detected to date. Considering the alignment of inclination angle in a 3-D magnetosphere, it is possible that PSR J0250+5854 has a high magnetic field comparable with magnetars or/and high magnetic field pulsars, if a small inclination angle is considered. Our calculations show that similar long-period pulsars tend to have a relatively low period derivative in this case. In another case of magnetic field decay, calculations also show a possible connection between PSR J0250+5854 and high dipole-magnetic field magnetars. The evolutionary path indicates a relatively high spin-down rate for similar long-period pulsars.

description: In this contribution, a computational approach for the manufacturing of multi-material lightweight parts is presented. For an efficient online optimization procedure, a proper orthogonal decomposition on offline obtained numerical results is carried out to construct a surrogate model. The functionality of the proposed framework is demonstrated on a use case study of a multi-material component consisting of a sheet metal basic structure and a plastic reinforcement structure. The manufacturing process chain consists of a deep drawing process followed by an injection molding process of short fiber reinforced plastics. The proposed methodology provides a fast and accurate computational model for structural properties with respect to the process settings.

title: Adiposity and carotid atherosclerosis in two populations at very different risk of cardiovascular mortality: Norway and Russia
Creators: name: Imahori, Y
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 2019

description: Obesity is a key risk factor for cardiovascular disease (CVD). The aim of this PhD study was to investigate the associations of obesity and adiposity with carotid atherosclerosis, and, in particular, to examine the effect of general vs abdominal adiposity on the burden of carotid plaque. These associations were investigated in the Tromsø study in Norway and in the Know Your Heart study in Russia. These populations have very different cardiovascular mortality rates, with Russia having one of the highest rates in the world. In this context, the thesis looked at whether differences in carotid plaque burden between these populations can be explained by adiposity. Four anthropometric measures of adiposity were included, which involved body mass index, waist circumference, waist-to-hip ratio, and waist-to-height ratio. Carotid plaque burden, i.e. the presence of plaques, number of plaques, and total plaque area (TPA), was assessed using carotid ultrasound. In the Tromsø Study 5th survey (2001), there was strong evidence of an association between TPA and adiposity, especially abdominal adiposity, after adjustment for potential confounders (sex, smoking status, education). This association was largely mediated by cardio-metabolic CVD risk factors (blood pressure, cholesterol, glycosylated haemoglobin). These findings were confirmed in a prospective analysis assessing changes in plaque burden between the Tromsø Study 4th (1994-95) and 5th surveys. Comparison of the cross-sectional results from the Know Your Heart study (KYH) and Tromsø Study 7th wave (Tromsø 7) showed that women in KYH had higher levels of adiposity than in Tromsø 7, while levels were similar for men. Despite evidence that adiposity was associated with carotid plaque (presence of plaques and number of plaques), adiposity failed to explain the high burden of carotid plaque in KYH compared to Tromsø 7 in women as well as men. Explanations for the greater carotid plaque burden in Russia must be sought elsewhere, although reducing levels of obesity in Russia and Norway must be a priority for other reasons.

description: We discuss the geometry of dynamical triangulations associated with 3-dimensional and 4-dimensional simplicial quantum gravity. We provide analytical expressions for the canonical partition function in both cases, and study its large volume behavior. In the space of the coupling constants of the theory, we characterize the infinite volume line and the associated critical points. The results of this analysis are found to be in excellent agreement with the MonteCarlo simulations of simplicial quantum gravity. In particular, we provide an analytical proof that simply-connected dynamically triangulated 4-manifolds undergo a higher order phase transition at a value of the inverse gravitational coupling given by 1.387, and that the nature of this transition can be concealed by a bystable behavior. A similar analysis in the 3-dimensional case characterizes a value of the critical coupling (3.845) at which hysteresis effects are present.

description: In cold forging processes as well as in sheet-bulk metal forming, vast contact stresses result in severe tool wear and thus in tool failures. In order to achieve a sustainable production, a new manufacturing process is developed within the subproject T06 in the transregional collaborative research centre 73 at the Institute of Forming Technology and Machines (IFUM). In this subproject the influence of an oscillation superposition on a forming process is investigated. The new type of sheet-bulk metal forming (SBMF) process manufactures a component with internal and external gearing. Contact normal stresses and thus tool wear could be reduced by applying an oscillation superposition in the main force flow of the machine. To verify the positive results in other processes, the oscillation method is applied to an industrial-like process based on anchor bolt manufacturing of Fischerwerke GmbH & Co. KG. For this purpose, a representative tool system is developed using numerical simulation. The numerical simulation is also used to investigate resulting local contact stresses and relative sliding velocities. Furthermore, cylinder compression tests with and without oscillation superposition are conducted for the workpiece stainless steel 1.4362 (AISI S32304), in order to qualify the reduction of contact stress.

description: New particle acceleration schemes open up exciting opportunities, potentially providing more compact or higher-energy accelerators. The AWAKE experiment at CERN is currently taking data to establish the method of proton-driven plasma wakefield acceleration. A second phase aims to demonstrate that bunches of about $10^9$ electrons can be accelerated to high energy, preserving emittance and that the process is scalable with length. With this, an electron beam of $O$(50 GeV) could be available for new fixed-target or beam-dump experiments searching for the hidden sector, like dark photons. The rate of electrons on target could be increased by a factor of more than 1000 compared to currently available, leading to a corresponding increase in sensitivity to new physics. Such a beam could also be brought into collision with a high-power laser and thereby probe the completely unmeasured region of strong fields at values of the Schwinger critical field. An ultimate goal is to produce an electron beam of $O$(3 TeV) and collide with an LHC proton beam. This very high energy electron-proton collider would probe a new regime in which the structure of matter is completely unknown.

description: The single-particle energy spectrum of a two-dimensional electron gas in a perpendicular magnetic field consists of equally-spaced spin-split Landau levels, whose degeneracy is proportional to the magnetic field strength. At integer and particular fractional ratios between the number of electrons and the degeneracy of a Landau level (filling factors n) quantum Hall effects occur, characterised by a vanishingly small longitudinal resistance and quantised Hall voltage. The quantum Hall regime offers unique possibilities for the study of cooperative phenomena in many-particle systems under well-controlled conditions. Among the fields that benefit from quantum-Hall studies is magnetism, which remains poorly understood in conventional material. Both isotropic and anisotropic ferromagnetic ground states have been predicted and few of them have been experimentally studied in quantum Hall samples with different geometries and filling factors. Here we present evidence of first-order phase transitions in n = 2 and 4 quantum Hall states confined to a wide gallium arsenide quantum well. The observed hysteretic behaviour and anomalous temperature dependence in the longitudinal resistivity indicate the occurrence of a transition between the two distinct ground states of an Ising quantum-Hall ferromagnet. Detailed many-body calculations allowed the identification of the microscopic origin of the anisotropy field.

description: The process of repairing damaged tool moulds is conducted manually in the industry. This results in long process times as well as a high dependence of the repair result on the experience of the worker. After a visual inspection, the detected damages are removed by metal cutting and the missing material is filled by a build-up welding process. Afterwards, the target geometry is restored via machining re-contouring process. Because of the individual tool mould surface and welded seam, each repair case requires an individual machining strategy as well as toolpaths and process control parameters to ensure high surface quality and shape accuracy. This paper introduces an innovative design for re-contouring of repair-welded tool moulds, which takes into consideration the individual mould surface, repair welding and material properties. For that purpose, the actual geometry of the tool mould is measured directly in the CNC machine using an optical profile line sensor. Based on the measurement, the re-contouring process is planned automatically by means of a computer aided manufacturing (CAM) software. A material removal simulation with cutting force prognosis is carried out to adapt the process parameters individually with regard to repair time and surface quality. To set up the force and surface simulation model with high model quality, re-contouring experiments are carried out on welded seams made of 1.2343 (AISI H11) as well as on Toolox 44 and 1.2343 workpieces for comparison.

description: In the current era of radio astronomy, continuum surveys observe a multitude of objects with complex morphologies and sizes, and are not limited to observing point sources. Typical radio source extraction software generates catalogues by using Gaussian components to form a model of the emission. This may not be well suited to complicated jet structures and extended emission, particularly in the era of interferometers with a high density of short baselines, that are sensitive to extended emission. In this paper, we investigate how the optically-motivated source detection package ProFound (Robotham et al. 2018) may be used to model radio emission of both complicated and point-like radio sources. We use a combination of observations and simulations to investigate how ProFound compares to other source extractor packages used for radio surveys. We find that ProFound can accurately recover both the flux densities of simulated Gaussian sources as well as extended radio galaxies. ProFound can create models that trace the complicated nature of these extended galaxies, which we show is not necessarily the case with other source extraction software. Our work suggests that our knowledge of the emission from extended radio objects may be both over or under-estimated using traditional software. We suggest that ProFound offers a useful alternative to the fitting of Gaussian components for generating catalogues from current and future radio surveys. Furthermore, ProFound's multi-wavelength capabilities will be useful in investigating radio sources in combination with multiwavelength data.

Publisher: name: Zenodo
Year: 2012

description: A presentation covering the DAP2 data model as it relates to the Open Geospatial Consortium (OGC) abstract specifaction. Presented at the 2012 OGC Technical Committee meeting in Austin, TX. 

Summary: 

The presentation outlines the Data Access Protocol version 2 (DAP2) data model and its relation to servers, coverages, and various types of grids, using examples such as UGrid work with NOAA. It explains that the data model encompasses variables, operations, and datasets, with servers implementing these operations and providing additional features. DAP2 is described as domain-neutral, intended to be a lower level in a multi-tier protocol stack, compatible with standards like COARDS and CF. The data model includes variables with syntactic and semantic metadata, operations for data extraction, and servers offering web interfaces.

description: This publication deals with finite element based modelling and the experimental validation of the flow characteristics of glass mat reinforced thermoplastic composite (GMT). Furthermore, the interaction of GMT and UD-Tape inserts is examined. The simulation model is set up in LS-Dyna. In order to model the high degree of deformation of the GMT the smooth particle hydrodynamics (SPH) method is used. A viscoplastic material model is applied in order to take into account the strain rate as well as strain hardening flow behavior. For the experimental validation of the numerical investigations, a heated plate tool with a surface area of 300 x 300 mm was built. This tool contains two internal pressure sensors as well as a temperature sensor. With the help of this test setup, it is possible to investigate the pressure build-up, pressure differences and surface temperatures of the GMT as well as the time-dependent position of the flow front. In addition, to pressure differences over the contact area between tool and GMT, there are differences in wall thickness, fiber orientation and fiber matrix separation depending on the flow path. The forming tests were carried out at a tool temperature of 115 °C. After the validation of the simulation model the fiber displacement of UD-Tapes insert is discussed.

description: Accounting for the two independent correlation functions of the QCD vacuum, we improve the simple and consistent description given by the model of the stochastic vacuum to the high-energy pp and pbar-p data, with a new determination of parameters of non-perturbative QCD. The increase of the hadronic radii with the energy accounts for the energy dependence of the observables.

Testing Oral Proficiency in Greek as a Foreign Language
Creators: name: Pavlou, Pavlos
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 1998

description: The increased interest in learning Greek as a Foreign Language (GFL) has brought with it the need of standardised tests in Greek in all skills (listening, speaking, reading, writing) and at all levels. This paper proposes a SOPI (Simulated Oral Proficiency Interview) as an appropriate instrument for testing oral proficiency in GFL. The structure, the advantages and disadvantages of the proposed SOPI is described and discussed. Moreover, the proposed SOPI is compared with the Oral Proficiency Interview (OPI) which is currently the most popular instrument for testing oral proficiency.

description: Metal matrix composite materials are of high interest for their increased stiffness, strength or wear resistance. Wear resistant composites contain hard ceramic particles to reduce microcutting and grooving of the metal matrix surface. In this paper, a gas atomised hot work tool steel X40CrMoV5-1 (1.2344/AISI H13) was combined with fused tungsten carbide (FTC) particles in order to create forging tools with increased abrasive wear resistance. For that purpose, tool components were manufactured by sinter-forging of stacked powder layers to build up a graded hard phase concentration of up to 10 vol.-%. Subsequently, sinter-forged specimens were combined with basic hot work tool steel components and joined by diffusion bonding to assemble the complete tool. In order to evaluate their performance, the tools were examined in a hot backward can extrusion process of low-alloyed steel. Optical geometry measurements, light microscopy and scanning electron microscopy of the worn tool radii indicated a significant decrease in abrasive wear when using FTC-reinforced tools rather than conventional hardened tool steel.
Considerations for Evaluating Junior EFL Coursebooks: From Theory to Practice
Creators: name: Sougari, Areti-Maria
name: Ziaka, Ioanna
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 1998

description: This paper looks into the various aspects that need to be considered for the evaluation of EFL coursebooks for young learners in the early stages of their learning. An attempt will be made to establish certain issues that should be accounted for by the language teacher when opting for a suitable coursebook. At the same time, we will look at three recently published coursebooks available in the market, examining the way in which and the degree to which these criteria are met. While trying to explore the type of activities that would be appropriate for young learners, we will discuss considerations, such as the particular cognitive characteristics and needs of these learners, the study skills that make them autonomous, and the development of their language awareness. In addition, we will look into the importance of interactive communication through problem-solving tasks and information-gap activities, group- and pair-work, games and songs. Reference will be made to the kind of activities incorporated in certain coursebooks and the way these coursebooks cater for the considerations set in order to provide guidance to the teacher who is faced with a plethora of materials available.

description: The first results of the solar neutrino flux measurement from Super-Kamiokande are presented. The results shown here are obtained from data taken between the 31st of May, 1996, and the 23rd of June, 1997. Using our measurement of recoil electrons with energies above 6.5 MeV, we infer the total flux of 8B solar neutrinos to be 2.42+-0.06(stat.)+0.10-0.07(syst.)*10^6/cm^2/s. This result is consistent with the Kamiokande measurement and is 36% of the flux predicted by the BP95 solar model. The flux is also measured in 1.5 month subsets and shown to be consistent with a constant rate.

Enhanced fermion pairing and superfluidity by an imaginary magnetic field

description: We show that an imaginary magnetic field(IMF), which can be generated in non-Hermitian systems with spin-dependent dissipations, can greatly enhance the s-wave pairing and superfluidity of spin-1/2 fermions, in distinct contrast to the effect of a real magnetic field. The enhancement can be attributed to the increased coupling constant in low-energy space and the reduced spin gap in forming singlet pairs. We have demonstrated this effect in a number of different fermion systems with and without spin-orbit coupling, using both the two-body exact solution and many-body mean-field theory. Our results suggest an alternative route towards strong fermion superfluid with high superfluid transition temperature.

description: This research describes the development of a combined process of forming and thermal joining without adhesives of high strength steels and organosheets. In order to achieve cycle times below 20 s the temperature of the forming tool remains constant at 110 °C throughout the process. Thus, the removal of the component can take place immediately after the forming process without cooling of the forming tool. The thermal energy required to assure the thermal joining process at 280 °C at the beginning of the intermediate forming step is applied by means of heating the steel in a furnace before the transfer to the forming tool. By choosing certain coating depended heat treatment parameters during the heating step, galvannealed rough surfaces of the steel blanks can be generated in order to increase the joint strength. The paper includes a surface analysis and lap-shear testing results to quantify the respective joint strength to be achieved with the proposed surface treatment. In addition tensile test results of the heated DP800 steel to characterize the thermal influence on the mechanical properties of the heated high-strength steels will be shown. Furthermore the paper presents a tool concept with a graded blank holder to perform stretching of the metal on the one hand and draping of the organosheet on the other hand as well as preliminary forming results.

description: Transport across an La$_{0.7}$Sr$_{0.3}MnO$_{3}/YBa$_{2}Cu$_{3}$O$_{7}$(LSMO/YBCO), interface is studied as a function of temperature and surface morphology. For comparison, control measurements are performed in non-magnetic heterostructures of LaNiO$_{3}$/YBCO and Ag/YBCO. In all cases, YBCO is used as bottom layer to eliminate the channel resistance and to minimize thermal effects. The observed differential conductance re ects the role of Andreev bound states in a-b planes, and brings out for the first time the suppression of such states by the spin-polarized transport across the interface. The theoretical analysis of the measured data reveals decay of the spin polarization near the LSMO surface with temperature, consistent with the reported photoemission data.
