An Edge-integrated Connection for Segmented Glass Beams
Creators: name: Teeuwen, A.S.
Publisher: name: Challenging Glass Conference Proceedings
Year: 2016

description: There are different options to obtain a structural glass beam with a span of more than 6 meters. One option is segmentation, which has many advantages compared with the other options. However, the choice for segmentation is often avoided, because of aesthetic reasons. Existing connections, even the most slender ones, result in a reduction of the transparency of the beam. While transparency is the key reason to use glass beams. In this paper a connection is presented that should improve the transparency of segmented glass beam. The connection is integrated in the least transparent part of a glass segment, the edge. It has a twofold effect; the transparency of the beam will decrease less, and by following the contours of the segment the connection is less noticeable. Since such a connection seems to be highly compatible with edge-integrated steel reinforcement, which can be applied to reach safe failure behavior, it is investigated how reinforced beam segments can be connected in an edge-integrated way. A connection is designed and its performance is determined by finite element analysis and physical testing of prototypes.

Material Properties of a Structural Silicone for Linear Adhesive Glass-Metal Connections

Publisher: name: Challenging Glass Conference Proceedings
Year: 2016

description: During recent years, adhesives are more frequently used for glass applications in buildings, and according knowledge on adhesive glass-metal connections increased exponentially. However, further research regarding the performance of such connections remains indispensable to further optimise existing concepts or to develop and implement new technologies. To analyse the mechanical behaviour of adhesive glass-metal connections, computer simulations based on the finite element method can be performed. To do so, material properties of all components have to be introduced in the form of stress-strain curves, which can be obtained through experimental tests on adhesive bulk material. Here, the focus is on adhesives suitable to transfer significant loads between a structural glass panel and a thin-walled steel frame. In this contribution, the material properties of a structural silicone, Sikasil® SG-500, were determined through several experiments. Tensile tests on dumbbells, compression tests on cylindrical samples and thick adherends shear tests (TAST) were performed according to the available standards. Different displacement rates were considered to study the visco-hyperelastic behaviour of the structural silicone. Subsequently, possible theoretical material laws were assessed for their ability to approximate the experimental obtained stress-strain relationships. This paper describes the test procedures, reports about the fabrication process of the test samples, presents the obtained experimental data and proposes possible material laws for the silicone. From the tests, no significant differences in tensile strength and shear strength were obtained for the displacement rates used in this research. However, the stiffness in tension, compression and shear did depend on the test speed.

description: Knowing the value of biodiversity would enable more efficient preservation choices. For this purpose it is useful to have quantitative and/or qualitative information on the object “biodiversity”. We sum up here several literatures (ecology, biology, political sciences and economics) which attempt to define and measure biodiversity. The originality of this note is that it clarifies the axiomatic bases of the indicators. While theoretical bases are sometimes fragile and need to be confirmed, practical issues are also a challenge for research.

description: A triangular lattice selenide series of rare earth (RE), CsRESe2, were synthesized as large single crystals using a flux growth method. This series stabilized in either trigonal (R-3m) or hexagonal (P63/mmc) crystal systems. Physical properties of CsRESe2 were explored by magnetic susceptibility and heat capacity measurements down to 0.4 K. Antiferromagnetic interaction was observed in all magnetic compounds, while no long-range magnetic order was found, indicating the frustrated magnetism. CsDySe2 presents spin freezing at 0.7 K, revealing a spin-glass state. CsCeSe2 and CsYbSe2 present broad peaks at 0.7 K and 1.5 K in the magnetization, respectively, suggesting the short-range interactions between magnetic rare earth ions. The lack of signature for long-range magnetic order and spin freezing down to 0.4 K in these compounds (RE = Ce, Yb) implies their candidacy for quantum spin liquid state.

description: Abstract: SentryGlas® foil has been used for over a decade as a laminating foil but also to bond metal inserts to glass. Most famously in the Apple cube and other Apple buildings and staircases. Although the joint is transparent and statically strong, little is known about the long term behaviour. Specimens were prepared of perforated stainless steel and glass. These were laminated using SentryGlas® foil. Tensile tests, fatigue tests and creep tests were conducted at room temperature and additional creep/fatigue tests at 40⁰C. The results are analysed and conclusions about the mechanisms involved and the safety are drawn.

description: We present and analyze FUSE observations of six solar analogs. These are single, main-sequence G0-5 strs selected as proxies for the Sun at several stages of its main-sequence lifetime. The emission features in the FUSE 920-1180 A wavelength range allow for a critical probe of the hot plasma over three decades in temperature. Using the flux ratio CIII 1176/977 as diagnostics, we investigate the dependence of the electron pressure of the transition region as a function of the rotation period, age and magnetic activity. The results from these solar proxies indicate that the electron pressure of the stellar ~10^5-K plasma decreases by a factor of about 70 between the young, fast-rotating magnetically active star and the old, slow-rotating inactive star. Also, the observations indicate that the average surface fluxes of emission features strongly decrease with increasing stellar age and longer rotation period. The emission flux evolution with age or rotation period is well fitted by power laws, which become steeper from cooler chromospheric (10^4 K) to hotter coronal (10^7 K) plasma. The relationship for the integrated (920-1180 A) FUSE flux indicates that the solar far-ultraviolet emissions were about twice the present value 2.5 Gyr ago and about 4 times the present value 3.5 Gyr ago. Note also that the FUSE/FUV flux of the Zero-Age Main Sequence Sun could have been higher by as much as 50 times. Our analysis suggests that the strong FUV emissions of the young Sun may have played a crucial role in the developing planetary system, in particular through the photoionization, photochemical evolution and possible erosion of the planetary atmospheres.

Performance-Based Concept for Design of Structural Silicone Joints in Façades Exposed to Earthquake

Publisher: name: Challenging Glass Conference Proceedings
Year: 2016

description: Façade failure due to seismic event represents a potential hazard to people and can cause serious damages to buildings with consequent high-cost remedial works. As a result, interest in the design of buildings and façades to resist seismic loads and displacements has increased. Current standards and literature recognize the benefits offered by Structural Sealant Glazing (SSG) systems to enhance the performance of unitized curtain walls exposed to earthquake but no precise criteria are available for the seismic design of the structural silicone joints. This paper proposes a design concept to evaluate the effect of forces and displacements imposed to the structural joints due to panel seismic racking; referring to the design philosophy developed by Japanese Standard, the concept is engineered based on three performance levels associated to different design requirements which aim at balancing costs and risks with no compromise on safety. Tensile and shear tests performed on sealant H-specimens and Hockman cycle tests simulating accelerated life cycles at different deformation rates are used to exploit the deformation capability of the joints correlated to residual strengths. Results from static racking tests on full-scale façade panels are used to validate the proposed design concept.

For mu>Sigma_0, the constituent quark mass in vacuum, chiral symmetry is restored and a diquark condensate forms. We analyse the fermion propagator and find evidence for particle-hole mixing in the vicinity of the Fermi surface and an energy gap Delta>0, both of which provide evidence for superfluidity at high baryon density induced by a BCS mechanism. At (mu a)=0.8 the ratio between the BCS gap and the vacuum quark mass is Delta/Sigma_0=0.15(2).

description: In France, there is a recurrent debate on the choice of organization, management modes and regulation of the water services. They are local monopolies which may be directly managed by the municipality or delegated to a private operator. An econometric analysis of cost for the drinking-water supply services gives crucial information on the potential gains in terms of network performance and resource management. A counterfactual comparison of the costs of the management modes (public/private) shows the differences in efficiency and the existence of an informational rent for private operators.

description: Polarimetry in the far-infrared and submillimeter has been valuable in tracing magnetic fields in bright Galactic Clouds. We discuss the techniques we have developed and trends we have found in polarization vs column density, and vs wavelength. The polarization spectrum has proven to be more interesting than had been anticipated. It is potentially valuable in explaining grain alignment and in characterizing dust species. One can expect the infrared cirrus to be a much simpler environment than the molecular clouds that have heretofore been explored at multiple wavelengths. Although cirrus observations must deal with low signals and wide extent, it is becoming possible to measure accurately the spectral energy distribution from mid-infrared to microwave frequencies and it should soon become feasible to determine the polarization spectrum over the same range.

The strength of glass, hidden damage
Creators: name: Veer, Frederic
name: Rodichev, Yurii
Publisher: name: Challenging Glass Conference Proceedings
Year: 2016

description: The strength of float glass is a necessary engineering parameter. Determining this strength is a complex problem. Earlier results have shown that statistically bending test results are not a homogeneous group. To explain this, a theory of “hidden damage” is proposed. The essence of this theory is that the different sides of float glass are unequal, not only because of the differences between the Tin and nitrogen sides, but because of the difference between the side scored under the sheet glass cutting and the side which has the crack propagation from the scored side in breaking. Extensive tests on rolled glass suggest that the rolling process damages the glass in a special way, causing “invisible” damage – statistically not a homogeneous distribution of micro-cracks on the edge surface of glass element. These micro-cracks are different on the scored and broken sides of glass. They are the fracture source under the loading and influence negatively on glass element strength and statistics of strength data.This “invisible” damage explains most if not all of the non-homogenous distribution of the test results. It is shown that removal of this damage on the edges of glass elements increases the engineering strength of float glass significantly.

description: Surfactin is an excellent biosurfactant with a wide range of application prospects in many industrial fields. However, its low productivity and high cost have largely limited its commercial applications. In this review, the pathways for surfactin synthesis in Bacillus strains are summarized and discussed. Further, the latest strategies for improving surfactin production, including: medium optimization, genome engineering methods (rational genetic engineering, genome reduction, and genome shuffling), heterologous synthesis, and the use of synthetic biology combined with metabolic engineering approaches to construct high-quality artificial cells for surfactin production using xylose, are described. Finally, the prospects for improving surfactin synthesis are discussed in detail.

description: The „Ostwall“, one of Krefeld‘s most important public traffic intersections, is getting modernized completely for the moment. The highlight of the project is the new canopy for the tram and bus stop. It was decided to realize a steel-glass structure, to get most possible transparency. The structure has a length of 125m and a width of 12m. The main structure has 9 column brackets, that are bearing a space truss. These elements are made of steel. For the roofing, partially curved glass elements are used, that are bonded to a stainless steel frame by structural silicone. The slope of the roofing reaches to the gutter in the middle axis of the building. For each side, only one glass element is used, to guarantee a good flow of rain water. The glass elements have a developed length of 5.2m and a width of 2.2m. At the front ends of the structure, spherically curved glass elements are used. The glass roof is accessible for cleaning and inspection work. To get a smooth view of the bottom surface, the glass is bonded under the steel frame, so the silicone bonding is used to bear the self-weight of the glass elements. The pre-fabricated elements are fixed to the main structure at the bottom girder of the framework directly, and at the top girder by a suspension bar. To get a minimized cross section of the stainless steel bars, they are stabilized by the glass elements to prevent them from torsional-flexural buckling.

Economic impacts of drought on agriculture

description: The scientific collective assessment on “Agriculture and drought” steered by INRA in 2006 showed a lack of quantitative analyses on the economic impact of a drought in France. In response, the INRA economists have built an original coupling between the STICS agronomic model developed by INRA and an economic model. The aim was to assess the cost of drought episodes to a representative farmer of the Midi-Pyrénées region and to determine whether his short or long term decisions help reducing this cost significantly. The results obtained indicate that, in the short term, the cost induced by the drought can be high. In the long term, that is to say if farming systems can be modified by the farmer, the cost induced by drought is attenuated in a visible way by these additional adaptation capacities. Moreover, the implementation of early-warning drought mechanisms may be beneficial to Midi-Pyrénées farmers.

description: We investigate the quantum chaotic properties of the Dicke Hamiltonian; a quantum-optical model which describes a single-mode bosonic field interacting with an ensemble of $N$ two-level atoms. This model exhibits a zero-temperature quantum phase transition in the $N \go \infty$ limit, which we describe exactly in an effective Hamiltonian approach. We then numerically investigate the system at finite $N$ and, by analysing the level statistics, we demonstrate that the system undergoes a transition from quasi-integrability to quantum chaotic, and that this transition is caused by the precursors of the quantum phase-transition. Our considerations of the wavefunction indicate that this is connected with a delocalisation of the system and the emergence of macroscopic coherence. We also derive a semi-classical Dicke model, which exhibits analogues of all the important features of the quantum model, such as the phase transition and the concurrent onset of chaos.

title: A Market Microstructure Analysis of Foreign Exchange Intervention in Canada

Publisher: name: Bank of Canada
Year: 2002

description: This paper clarifies the role and the impact of foreign exchange dealers in the relationship between foreign exchange intervention and nominal exchange rates using a unique dataset that disaggregates trades by dealer and by type of trade. The paper tests a number of market microstructure hypotheses. Results suggest that central bank orders and other customer orders are treated similarly by dealers who are engaged in short-run speculative and risk-sharing-motivated interdealer trading. While private payoff-relevant information is contained in trades, speculative interdealer trading is based only on transitory non-payoff-relevant information. A central bank considering intervention must consider both the signal it wishes to convey to the market and the subsequent trading strategies utilized by dealers.
description: Dans cette étude, l'auteur clarifie le rôle que jouent les cambistes dans la relation entre les interventions sur le marché des changes et les taux de change nominaux. Pour ce faire, il recourt à un ensemble unique de données sur les opérations, décomposées par cambiste et par type de client. Il vérifie également un certain nombre d'hypothèses relatives à la microstructure du marché. D'après les résultats qu'il obtient, les ordres émanant de la banque centrale et des autres clients sont traités de la même façon par les cambistes qui concluent avec d'autres cambistes des opérations spéculatives à court terme, motivées par le partage des risques. S'il est vrai que les opérations intègrent des informations privilégiées liées à la valeur anticipée des actifs, celles que les cambistes mènent à des fins spéculatives, pour leur part, se fondent uniquement sur des informations transitoires non liées à la valeur anticipée. Une banque centrale qui envisage de procéder à une intervention doit tenir compte tant du signal qu'elle souhaite transmettre au marché que des stratégies ultérieures adoptées par les cambistes.

description: We present the first results of an observational programme at the ESO Very Large Telescope aimed at detecting a large sample of high-redshift galaxies fainter than the current spectroscopic limit of R=25.5 for Lyman-Break galaxies. In this paper, we describe the results of deep narrow and broad-band imaging and subsequent follow-up multi-object spectroscopy of faint high-redshift galaxies in the fields of the BRI1346-0322 and Q2138-4427. These QSOs have intervening absorbers, at redshifts z=2.85 and z=3.15 respectively, for which redshifted Ly-alpha emission falls within less than a few AA from the central wavelengths of existing VLT (~60 AA wide) narrow-band filters. We selected 37 and 27 candidate emission-line galaxies in the two fields respectively. About 85% of the candidates have R-band magnitudes fainter than R=25.5. The first spectroscopic follow-up of a sub-sample of the candidates resulted in 41 confirmed candidates and 4 foreground galaxies (three [OII] emitters and one CIV emitter). The confirmation rate is 82% and 68% in the field of BRI1346-0322 and Q2138-4427 respectively. In addition, we serendipitously detect a number of other emission-line sources on some of the slitlets not used for candidates. Of these, 9 are also most likely Ly-alpha emitters with redshifts ranging from 1.98 to 3.47. The redshift distribution of confirmed candidates in the field of BRI1346-0322 is consistent with being drawn from a uniform distribution weighted by the filter response curve, whereas the galaxies in the field of Q2138-4427 have redshifts clustering very close to the redshift of the damped Ly-alpha absorber. This latter fact indicates the existence of a large `pancake'-like structure confirming the earlier suggestions of Francis & Hewitt (1993).

Determination of Bending Tensile Strength of Thin Glass
Creators: name: Neugebauer, J.
Publisher: name: Challenging Glass Conference Proceedings
Year: 2016

description: Glass with a thickness of 0.55 up to 2.0 mm can be defined as a thin glass or even as ultra-light. On the market there are several suppliers, which offer such thin glass. On the one hand there are e.g. Gorilla Glass produced by Corning Incorporated or Leoflex by AGC, which are pre-stress by chemical treatment and on the other hand there are soda lime silicate glass products, which are pre-stress by thermal or chemical treatment. Not only the design with thin glass causes a totally new kind of thinking, also possible test scenarios for determination of the ultimate bending strength are currently not distinctly regulated in standards. Some existing test set-ups described in standards e.g. EN 1288 (four-point bending test or large ring on ring test) cannot be used for the determination of the ultimate bending tensile strength of thin glass. Different test set-ups published in several papers show possibilities for alternative determination of ultimate bending strength. These different configurations were investigated and analyzed for their applicability for determination of bending strength of thin glass.

description: RX J0806+15 has recently been identified as the binary system with the shortest known orbital period. We present a series of observations of RX J0806+15 including new optical observations taken one month apart. Using these observations and archival data we find that the period of this system is decreasing over time. Our measurements imply f_dot = 6.11x10^-16 Hz/s, which is in agreement with a rate expected from the gravitational radiation for two white dwarfs orbiting at a given period. However, a smaller value of f_dot = 3.14x10^-16 Hz/s cannot be ruled out. Our result supports the idea that the 321.5 s period is the orbital period and that the system is the shortest period binary known so far and that it is one of the strongest sources of constant gravitational radiation in the sky. Furthermore, the decrease of the period strongly favours the unipolar inductor (or electric star) model rather than the accretion models.

Network dynamics of ongoing social relationships

description: Many recent large-scale studies of interaction networks have focused on networks of accumulated contacts. In this paper we explore social networks of ongoing relationships with an emphasis on dynamical aspects. We find a distribution of response times (times between consecutive contacts of different direction between two actors) that has a power-law shape over a large range. We also argue that the distribution of relationship duration (the time between the first and last contacts between actors) is exponentially decaying. Methods to reanalyze the data to compensate for the finite sampling time are proposed. We find that the degree distribution for networks of ongoing contacts fits better to a power-law than the degree distribution of the network of accumulated contacts do. We see that the clustering and assortative mixing coefficients are of the same order for networks of ongoing and accumulated contacts, and that the structural fluctuations of the former are rather large.

title: Estimated DGE Models and Forecasting Accuracy: A Preliminary Investigation with Canadian Data
Creators: name: Moran, Kevin

Publisher: name: Bank of Canada
Year: 2002

description: This paper applies the hybrid dynamic general-equilibrium, vector autoregressive (DGE-VAR) model developed by Ireland (1999) to Canadian time series. It presents the first Canadian evidence that a hybrid DGE-VAR model may have better out-of-sample forecasting accuracy than a simple, structure-free VAR model. The evidence suggests that estimated DGE models have the potential to add good forecasting ability to their natural strength of adding structure to an economic model.
description: Dans cette étude, les auteurs appliquent aux séries chronologiques canadiennes le modèle hybride dynamique d'équilibre général et vectoriel autorégressif conçu par Ireland (l999). Les résultats montrent pour la première fois, dans le cas du Canada, que l'exactitude des prévisions hors échantillon peut être supérieure dans un modèle hybride de ce type que dans un modèle VAR simple sans structure. Les observations laissent croire que les modèles dynamiques d'équilibre général estimés peuvent allier un bon pouvoir de prévision à leur capacité naturelle de structurer un modèle économique.
Implementation of controllable universal unital optical channels

description: We show that a configuration of four birefringent crystals and wave-plates can emulate almost any arbitrary unital channel for polarization qubits encoded in single photons, where the channel settings are controlled by the wave-plate angles. The scheme is applied to a single spatial mode and its operation is independent of the wavelength and the fine temporal properties of the input light. We implemented the scheme and demonstrated its operation by applying a dephasing environment to classical and quantum single-photon states with different temporal properties. The applied process was characterized by a quantum process tomography procedure, and a high fidelity to the theory was observed.

Effects of Interlayer Weathering on the Structural Behaviour of Laminated Glass Structures

Publisher: name: Challenging Glass Conference Proceedings

description: Many studies reported in the literature are able to demonstrate significant influence of weathering on physical and mechanical properties of PVB. In this paper, the results of these researches are compared and discussed. The effects of rheological parameters modifications on the coupling capability of laminated glass structural elements and on the mechanical response to loads are then evaluated through numerical analysis. Real structures are often exposed to direct sunlight or to temperature or humidity levels that can induce damage phenomena in the interlayer; the modification of mechanical coupling capability and of adhesion properties of interlayer that effectively take place in laminated glass structures have to be taken into account in the design process as they probably affect the behavior of the structure not only in the serviceability state but especially in the ultimate limit state.

Structural Glazing: Design under High Windload

description: Bonding of glass onto aluminum frames, known as “Structural Silicone Glazing”, has been applied for more than 40 years in glass curtain wall facades. Silicone sealants are being used in this application because of their outstanding resistance to weathering (UV, temperature, moisture, ozone), They also provide resistance to water egress and thermal insulation. Their role, structurally, is to resist to windloads and to compensate for differential thermal expansion of glass and aluminum frame. For windload resistance, silicone bite is calculated using a simplified equation which assumes a uniform stress distribution along the sealant bite. Finite Element Analysis (FEA) was used in this study calculate the stress distribution in the sealant as a function of sealant bite and thickness and show the importance of the sealant geometry (bite and thickness) on the local stress distribution. The study shows that for glass deflections in the 1% region (L/d=100), large sealant joints and/or high modulus sealants lead to higher local stresses.

description: We present studies of the photoluminescence (PL), absorption and Raman scattering from poly[2,7-(9,9'-bis(2-ethylhexyl))fluorene] under hydrostatic pressures of 0-100 kbar at room temperature. The well-defined PL and associated vibronics that are observed at atmospheric pressure change dramatically around 20 kbar in the bulk sample and at around 35 kbar for the thin film sample. Beyond these pressures the PL emission from the backbone is swamped by strong peaks due to aggregates and keto defects in the 2.1-2.6 eV region. The Raman peaks shift to higher energies and exhibit unexpected antiresonance lineshapes at higher pressures, indicating a strong electron-phonon interaction.

description: Reynolds-averaged Navier-Stokes (RANS) equations are presently one of the most popular models for simulating turbulence. Performing RANS simulation requires additional modeling for the anisotropic Reynolds stress tensor, but traditional Reynolds stress closure models lead to only partially reliable predictions. Recently, data-driven turbulence models for the Reynolds anisotropy tensor involving novel machine learning techniques have garnered considerable attention and have been rapidly developed. Focusing on modeling the Reynolds stress closure for the specific case of turbulent channel flow, this paper proposes three modifications to a standard neural network to account for the no-slip boundary condition of the anisotropy tensor, the Reynolds number dependence, and spatial non-locality. The modified models are shown to provide increased predicative accuracy compared to the standard neural network when they are trained and tested on channel flow at different Reynolds numbers. The best performance is yielded by the model combining the boundary condition enforcement and Reynolds number injection. This model also outperforms the Tensor Basis Neural Network (Ling et al., 2016) on the turbulent channel flow dataset.
