    2011-01-01

    The Hofstadter butterfly spectral patterns of lattice electrons in an external magnetic field yield some of the most beguiling images in physics. Here we explore the magneto-electronic spectra of systems with moire spatial patterns, concentrating on the case of twisted bilayer graphene. Because long-period spatial patterns are accurately formed at small twist angles, fractal butterfly spectra and associated magneto-transport and magneto-mechanical anomalies emerge at accessible magnetic field...

    to travelers without off-road vehicles. To accommodate various user preferences, we develop MOIR/UOTS, a trip recommendation system that supports User Oriented Trajectory Search (UOTS) [5], [7] based on our previous MOIR platform [2], [4]. Meanwhile, MOIR/UOTS also functions as a test-bed system for exploring......Trajectory search plays an important role in various applications such as trip planning and recommendation. However, most existing studies only focus on spatial proximity but ignore individual users' preferences. For example, it is inappropriate to recommend a route containing gravel roads...... and evaluating novel trajectory searching algorithms. In particular, we demonstrate how ordinary users can interact with MOIR/UOTS to search for trajectories with their preferences, and how MOIR/UOTS helps researchers to evaluate the performance of various algorithms...

    2001-08-01

    For several decades measurement optical techniques have been used in different branches of Science and Technology and in medicine. One of these techniques is the so-called Moire topography that allows the accurate measurement of different parts of the human body topography. This investigation presents the measurement of topographies of teeth and gums using an automated system of shadow moire, with which precision can be reached up to the order of the microns by the phase shift instrumentation in an original way. Advantages and disadvantages of using the Moire topography and its comparison with other techniques used in the optical metrology are presented. Also, some positive and negative aspects of the implementation of this technique are shown in dentistry.

    Use of moire patterns to determine positions extended to three dimensions. Concept requires two moire templates or grids, separated from each other. Template on side closer to observer contains alternating black and transparent areas. Template farther from observer contains alternating black and white areas. Observer determines position of center of perspective, also receiving indication of depth even without stereoscopic view. Used in rangefinding applications in which precision not required. Also used to gauge location of mobile robot in environment hostile to humans.

  5. New Methods in Moire Interferometry

    Science.gov (United States)

    Czarnek, Robert

    Experimental observations and measurements are the essential source of information necessary for correct development of mathematical models of real materials. Moire interferometry offers high sensitivity in full-field measurements of the in-plane displacements on the surface of the specimen. The (+OR-)45(DEGREES) method of moire interferometry increases the efficiency of a three-beam interferometer making its use outside of an optical laboratory more practical. Analysis of the (+OR-)45(DEGREES) method is provided. A concept of the vector representation of the fringe gradient is introduced and used in the analysis. Although existing systems require coherent light, the proposed system can use a relatively broad spectral bandwidth. Features that are related to the vibration sensitivity of such an instrument are investigated analytically. The basic concepts of an achromatic moire interferometry system are developed. Attachment of the critical elements of the system to the specimen solves the problem of relative rigid body motions, including vibrations, between the specimen and the virtual reference grating. Application of a laser diode light source reduces size, weight and cost of the interferometer making moire interferometry more practical for most materials testing laboratories. Laboratory tests confirmed the developed methods. This work enhances the probability of successful construction of a portable moire interferometer for measurements outside of the optical laboratory, in a mechanical testing or field environment.

  6. Moire interferometry with increased sensitivity

    Science.gov (United States)

    Han, Bongtae; Post, Daniel

    The basic sensitivity of moire interferometry was increased beyond the previously conceived theoretical limit. This was accomplished by creating the virtual reference grating inside a refractive medium instead of air, thus shortening the wavelength of light. A very compact four-beam moire interferometer in a refractive medium was developed for microscopic viewing, which produced a basic sensitivity of 208 nm per fringe order, corresponding to moire with 4800 lines per mm. Its configuration made it inherently stable and relatively insensitive to environmental disturbances. An optical microscope was employed as the image recording system to obtain high spatial resolution. The method was demonstrated for deformation of a thick graphite/epoxy composite at the 0/90 deg ply interface.

    In this study, a novel digital atomic force microscope (AFM) moire method is established to measure the displacement and strain fields. The moire pattern is generated by the interference between the specimen grating and the virtual reference grating formed by digital image processes. The overlapped image is filtered by the 2-D wavelet transformation to obtain clear interference moire patterns. From moire patterns, the displacement and strain fields can be analyzed. The experimental results show that the digital AFM moire method is very sensitive and easy to realize in nanoscale measurements.

    Fringe-carrier method is used in automatic fringe-order numbering of dynamic in-plane moire patterns. In experiment both static carrier and dynamic moire patterns are recorded. The image files corresponding to instants are set up to assign fringe orders automatically. Subtracting the carrier image from the modulated ones, the moire patterns due to the dynamic deformations are restored with fringe-order variation displayed by different grey levels.

    We have developed moiré nanosphere lithography (M-NSL), which incorporates in-plane rotation between neighboring monolayers, to extend the patterning capability of conventional nanosphere lithography (NSL). NSL, which uses self-assembled layers of monodisperse micro/nanospheres as masks, is a low-cost, scalable nanofabrication technique and has been widely employed to fabricate various nanoparticle arrays. Combination with dry etching and/or angled deposition has greatly enriched the family of nanoparticles NSL can yield. In this work, we introduce a variant of this technique, which uses sequential stacking of polystyrene nanosphere monolayers to form a bilayer crystal instead of conventional spontaneous self-assembly. Sequential stacking leads to the formation of moiré patterns other than the usually observed thermodynamically stable configurations. Subsequent O2 plasma etching results in a variety of complex nanostructures. Using the etched moiré patterns as masks, we have fabricated complementary gold nanostructures and studied their optical properties. We believe this facile technique provides a strategy to fabricate complex nanostructures or metasurfaces.

    We investigate surface plasmon polariton (SPP) cavitiy modes on two dimensional Moire surfaces in the visible spectrum. Two dimensional hexagonal Moire surface can be recorded on a photoresist layer using Interference lithography (IL). Two sequential exposures at slightly different angles in IL generate one dimensional Moire surfaces. Further sequential exposure for the same sample at slightly different angles after turning the sample 60 degrees around its own axis generates two dimensional hexagonal Moire cavity. Spectroscopic reflection measurements have shown plasmonic band gaps and cavity states at all the azimuthal angles (omnidirectional cavity and band gap formation) investigated. The plasmonic band gap edge and the cavity states energies show six fold symmetry on the two dimensional Moire surface as measured in reflection measurements.

    Asundi, A.; Cheung, M. T.

    The present use of moire interferometry for low amplitude vibration and analysis demonstrates the possibility of obtaining out-of-plane displacement contours whose sensitivity is comparable to that of holographic methods. A major advantage of the present system, is the obviation of prior knowledge of resonant frequencies, as called for in time-average holography. The experimental apparatus employed encompasses a laser beam, a parabolic mirror, a high frequency (600 line/mm) grating, and a camera, in addition to the test model.

    2011-01-01

    In the present work is proposed that dynamic moire-like fringe patterns produced by photorefraction, with low spatial frequencies, could be used for profile determination of small objects. The Fourier transform profilometry technique is applied in the projected moire fringe pattern onto an object surface. Basically, the Fourier transform of the projected fringes is obtained. After that, a phase map is generated. Then, the optical profile of object is obtained using phase unwrapping. So, the entire process can be indicated to measure, with good accuracy degree, profile of small objects in sub-micrometer scale in optical mechanical systems.

    We investigate surface plasmon polariton (SPP) coupled cavity modes on Moire surfaces. An experimental study has been made of the propagation of SPPs on a thin silver surface that is textured with Moire surface pattern using interference lithography. The Moire surface contains periodic array of one dimensional cavities. The distance between the cavities can be controlled by changing the periodicities of Moire surface. When the SPP cavity separation is sufficiently small, we show splitting of strongly coupled plasmonic cavity modes through numerical simulations. Conversely, when the SPP cavity separation is sufficiently large, SPP cavity modes are found to be localized and do not show splitting of SPP cavity modes . This splitting of SPP cavity modes are well explained with a tight binding model that has been succesfully applied in photonic coupled cavities. Reflection measurements and numerical simulation of a large number of adjacent SPP cavities have shown a coupled resonator optical waveguide (CROW) type plasmonic waveguide band formation within the band gap region of unperturbed uniform grating.

    For several decades, measurement of optical techniques has been used in different branches of science and technology. One of these techniques is the so-called moiré topography (MT) that enables the accurate measurement of different parts of the human body topography. This investigation presents the measurement of topographies of teeth and gums using an automated system of shadow moiré and the phase shift method in an original way. The fringe patterns used to compute the shape and the shape matrix itself are presented in the article. The phase shift method ensures precisions up to the order of microns. Advantages and disadvantages of using the MT are included. Besides, some positive and negative aspects concerned with the implementation of this technique in odontology are shown in the article.

    1983-01-01

    The very high sensitivity of moire interferometry has permitted the present edge effect experiments to be conducted at a low average stress and strain level, assuring linear and elastic behavior in the composite material samples tested. Sensitivity corresponding to 2450 line/mm moire was achieved with a 0.408 micron/fringe. Simultaneous observations of the specimen face and edge displacement fields showed good fringe definition despite the 1-mm thickness of the specimens and the high gradients, and it is noted that the use of a carrier pattern and optical filtering was effective in even these conditions. Edge effects and dramatic displacement gradients were confirmed in angle-ply composite laminates.

  17. Moire interferometry for vibration analysis of plates

    Asundi, A.; Cheung, M. T.

    1987-12-01

    Moire interferometry is used to locate nodal regions and measure vibration amplitudes of sinusoidally vibrating square plates. The high sensitivity afforded by this technique makes possible the study of plate vibrations at high frequencies and low amplitudes. The initial pattern is modulated by the zero-order Bessel function representing the vibratory motion. The fringe (or fringes) with best contrast indicate the nodal regions, while the higher order fringes, describing loci of points vibrating with the same amplitude, have decreasing contrast which is improved by spatial filtering.

    Moiré superlattices were generated in two-dimensional (2D) van der Waals heterostructures and have revealed intriguing electronic structures. The appearance of mini-Dirac cones within the conduction and valence bands of graphene is one of the most striking among the new quantum features. A Moiré superstructure emerges when at least two periodic sub-structures superimpose. 2D Moiré patterns have been particularly investigated in stacked hexagonal 2D atomic lattices like twisted graphene layers and graphene deposited on hexagonal boron-nitride. In this letter, we report both experimentally and theoretically evidence of superlattices physics in transport properties of one-dimensional (1D) Moiré crystals. Rolling-up few layers of graphene to form a multiwall carbon nanotube adds boundaries conditions that can be translated into interference fringes-like Moiré patterns along the circumference of the cylinder. Such a 1D Moiré crystal exhibits a complex 1D multiple bands structure with clear and robust interband quantum transitions due to the presence of mini-Dirac points and pseudo-gaps. Our devices consist in a very large diameter (>80 nm) multiwall carbon nanotubes of high quality, electrically connected by metallic electrodes acting as charge reservoirs. Conductance measurements reveal the presence of van Hove singularities assigned to 1D Moiré superlattice effect and illustrated by electronic structure calculations.

    In the electron moiré method,a high-frequency grating is used to measure microscopic deformation,which promises significant potential applications for the method in the microscopic analysis of materials.However,a special beam scanning control device is required to produce a grating and generate a moiré fringe pattern for the scanning electron microscope (SEM).Because only a few SEMs used in the material science studies are equipped with this device,the use of the electron moiré method is limited.In this study,an electron moiré method for a common SEM without the beam control device is presented.A grating based on a multi-scanning concept is fabricated in any observing mode.A real-time moiré pattern can also be generated in the SEM or an optical filtering system.Without the beam control device being a prerequisite,the electron moiré method can be more widely used.The experimental results from three different types of SEMS show that high quality gratings with uniform lines and less pitch error can be fabricated by this method,and moiré patterns can also be correctly generated.

    Intra-Landau level excitations in the fractional quantum Hall regime are not accessible via optical absorption measurements. We point out that optical probes are enabled by the periodic potentials produced by a moiré pattern. Our observation is motivated by the recent observations of fractional quantum Hall incompressible states in moiré-patterned graphene on a hexagonal boron nitride substrate, and is theoretically based on f -sum rule considerations supplemented by a perturbative analysis of the influence of the moiré potential on many-body states.

    1994-11-01

    An elegant measuring setup for contouring strong aspherical surfaces is introduced. Moire deflectometry is chosen as the measuring method because the configuration is simple, robust, and variable in sensitivity. The instrument is capable of measuring height deviations between an aspherical surface and its best fitting sphere ranging from minimally 1 micrometers to maximally 30 micrometers with a relative accuracy of 10%, which is useful for the production of surfaces in infrared optics. It is possible to measure transparent as well as reflecting surfaces, both convex and concave. A CCD-camera and a PC make part of the setup to automate the measurements. The short measurement time of less than 60 seconds makes the instrument useful in the manual production of aspherical surfaces.

    The precise measurement of forces is one way to obtain deep insight into the fundamental interactions present in nature. In the context of neutral antimatter, the gravitational inter- action is of high interest, potentially revealing new forces that violate the weak equivalence principle. Here we report on a successful extension of a tool from atom optics—the moire ́ deflectometer—for a measurement of the acceleration of slow antiprotons. The setup con- sists of two identical transmission gratings and a spatially resolving emulsion detector for antiproton annihilations. Absolute referencing of the observed antimatter pattern with a photon pattern experiencing no deflection allows the direct inference of forces present. The concept is also straightforwardly applicable to antihydrogen measurements as pursued by the AEgIS collaboration. The combination of these very different techniques from high energy and atomic physics opens a very promising route to the direct detection of the gravitational acceleratio...

    In this study, the digital atomic force microscope (AFM) Moire method with phase-shifting technology is established to measure the in-plane displacement and strain fields. The Moire pattern is generated by the interference between the specimen grating and the virtual reference grating formed by digital image processes. The overlapped image is filtered by two-dimensional wavelet transformation to obtain the clear interference Moire patterns. The four-step phase-shifting method is realized by translating the phase of the virtual reference grating from 0 to 2{pi}. The principle of the digital AFM Moire method and the phase-shifting technology are described in detail. Experimental results show that this method is convenient to use and efficient in realizing the microscale measurement.

    In previous papers [2,3,4,5] we introduced an operation based on digital moiré pattern processing to measure the distance to an object and its size. The method uses a sequence of digital photographic operations to capture two pictures of the scene with the CCD camera placed at two near and well defined positions along the optical axis of the camera. The distance ΔL between both camera positions is of the order of 1-10% of the distance L from the camera to the selected object in the scene. The teleoperation process algoritm requires to introduce ΔL to determine the distance L. Now we will report a simple and powerful optical system: an optical delay line with an optical path equal to 1.5 m, introduced in the line of sight from the camera to the selected object in the scene. With this optical system it is possible to capture the observed object at distances L and L+ΔL simultaneously in the same picture. The uncertainty in measuring L is of the order of 1%.

    In the paper, the main properties of Moire fringe, such as average effect, amplification effect, corresponding relation are elaborated, and the principle of Moire Ct technique is represented. On the basis of main features of Moire fringe, multidirectional Moire Ct deflection system is designed using high accuracy Ccd, grating, filter, lens, planar mirror and optical splitter. The system has simple light path, and can be easily made into the one that has large caliber.It can analyze multidirectional records of the probe at the same time, and can obtain clear interference patterns.The iterative technique combined with computer chromatography algorithms is used to achieve inversion of multidirectional clear interference patterns so that the required parameters can be acquired. Moire Ct technique is applied to laser flexible manufacture. Produced parts are delaminated on the paper, and are stratified manufactured until they are connected to forming. Cad/Cam system is adopted to construct Spatial three-dimensional geometric model, and the data files are formed. Then by using the Small triangle plane, the inner and outer surfaces of the data files are discretized. Discretized parts model is made chromatography with mathematical methods using Cam software. A series of parallel horizontal intersecting planes are generated. The problems of filtering arrangement tangent points are solved by recombining the shape and structure relationship among the triangular mesh. Several conclusions are presented.

    Science.gov (United States)

    Lawrence, George M.

    1989-01-01

    In electronic imaging detectors using microchannel plates, the mismatch between the pixels on a square mesh and the microchannels on a hexagonal mesh produces moire image defects. Theoretical statistical estimates of the sizes of the microposition offsets and the flat field intensity errors are calculated, showing the trade-off between resolution and position accuracy. A distinction is made between moments of spot images and moments of the single-pixel-response functions. As the resolution between the hex and square meshes is improved, the detector resolution is improved, but at the expense of an about 10 percent moire pattern. These moire patterns will not be properly corrected by dividing by the flat field image.

    2009-02-01

    We have demonstrated slow propagation of surface plasmons on metallic Moiré surfaces. The phase shift at the node of the Moiré surface localizes the propagating surface plasmons and adjacent nodes form weakly coupled plasmonic cavities. Group velocities around vg=0.44c at the center of the coupled cavity band and almost a zero group velocity at the band edges are observed. A tight binding model is used to understand the coupling behavior. Furthermore, the sinusoidally modified amplitude about the node suppresses the radiation losses and reveals a relatively high quality factor (Q=103).

    A moiré interferometer was designed and constructed based on a general system design using a reflective crossed-line diffraction grating to produce the four beams of light necessary for moiré interferometry. The design concept, basic design and tuning procedures are discussed. The important features of the interferometer, i.e. compactness, versatility, polarization insensitivity, relaxed collimation requirements, low laser power and remote optics, are addressed. Several such interferometers have been constructed and successfully applied to engineering problems. These include examining the displacement fields surrounding drilled and preformed holes in composite laminates loaded in tension, and the evaluation of nonhomogeneous behavior in textile composites.

    From its first conception to its first demonstration, plasmonic lasers have been an intriguing topic of research. In this work, Moiré gratings which manifest a cavity state in the SPP dispersion curve. We used a reverse Kretschmann setup to decouple the amplified light component of SPPs. We employed a Moiré cavity with 250 +256 nm periodicity together with a Styryl 7 laser dye dissolved in ethylene glycol in 5 mM concentration and obtained a lasing at 718 nm. Pumping threshold was 1.5 mJ/cm2 with FWHM of 2.8 nm. Furthermore, periodicities of 242 +248 nm and 260 +266 nm resulted in proportional shift of the lasing peak. We did not observe any lasing action on samples with Au and Ti coatings, although solely Au coated samples showed plasmonic modes in the spectrum. Resulting lasing peak is highly TM polarized. Reflection map measurements confirm that lasing mode is supported with the cavity state of the metallic Moiré cavity and simulations support reflection map measurements. Thus, we demonstrated, to our knowledge, the first plasmonic dye laser on a Moiré cavity. TUBITAK 110T790, 110T589, 112T091.

    Full Text Available The moiré effect and phenomena are natural occurring geometric formations that appear during the super-position of grid structures. Most widely recognisable in colour printing practices, generally viewed on screens (computer and TV they are in most cases examples of interference within a signal or a code, unwanted visual mis-alignment. Especially in digital image capture, moiré patternings appear when a geometrically even pattern, like a fabric or close-up of fine texture, has an appearance of rippled water with blue or red hues of concentric circle formations. The intriguing pattern formation in this case points back not only to the mis-alignment of frequencies, but can be further seen as the intersection point of a speculative ontology for the index of the digital image. Moiré not only as a visually reproducible phenomenon or effect, but a field of vision that blurs the boundaries between analogue and digital, perception and affect, manifesting the photographic as a constant site of becoming, a site of immanence. The philosophy of Henri Bergson, Brian Massumi and Francois Laruelle will be explored alongside the moiré image and phenomenon, to see if there is such a speculative site underlining the becoming of the digital image and its repercussions in contemporary digital culture.

    Sampling moiré effects are well known in signal processing. They occur when a continuous periodic signal g(x) is sampled using a sampling frequency f s that does not respect the Nyquist condition, and the signal-frequency f folds over and gives a new, false low frequency in the sampled signal. However, some visible beating artefacts may also occur in the sampled signal when g(x) is sampled using a sampling frequency f s which fully respects the Nyquist condition. We call these phenomena sub-Nyquist artefacts. Although these beating effects have already been reported in the literature, their detailed mathematical behaviour is not widely known. In this paper, we study the behaviour of these phenomena and compare it with analogous results from the moiré theory. We show that both sampling moirés and sub-Nyquist artefacts obey the same basic mathematical rules, in spite of the differences between them. This leads us to a unified approach that explains all of these phenomena and puts them under the same roof. In particular, it turns out that all of these phenomena occur when the signal-frequency f and the sampling frequency f s satisfy f≈(m/n)f s with integer m, n, where m/n is a reduced integer ratio; cases with n=1 correspond to true sampling moiré effects.

  14. High sensitivity moiré interferometry with compact achromatic interferometry

    Czarnek, Robert

    Experimental observations and measurements are the sources of information essential for correct development of mathematical models of real structural materials. Moiré interferometry offers high sensitivity in full-field measurements of in-plane displacements on the surface of a specimen. Although it is a powerful method in experimental stress analysis, it has some shortcomings. One is that existing systems require highly coherent light. The only sufficient source of light for this application is a long cavity laser, which is relatively expensive and at best cumbersome. Another shortcoming is that measurements must be performed in a vibration-free environment, such as that found on a holographic table. These requirements limit the use of existing moiré interferometers to a holographic laboratory. In this paper a modified concept of compensation is presented, which permits the use of a chromatic source of light in a compact moiré system. The compensator provides order in the angles of incident light for each separate wavelength, so that the virtual reference grating created by each wavelength in a continuous spectrum is identical in frequency and spatial position. The result is a virtual reference grating that behaves exactly like that created in coherent light. With this development the use of a laser diode, which is a non-coherent light source of tiny dimensions, becomes practical. The special configuration of the optics that create the virtual grating allows its synchronization with the specimen grating and leads to an interferometer design that is relatively insensitive to the vibrations found in a mechanical testing laboratory. Sensitivity to relative motion is analyzed theoretically. This development provides the oppurtunity to apply moiré interferometry to solid mechanics problems that cannot be studied in an optics laboratory. Experimental verification of the optical concepts is provided. A compact moiré interferometer based on the presented idea was

    Ifju, Peter G.

    1995-01-01

    The viability as an efficient aircraft material of advanced textile composites is currently being addressed in the NASA Advanced Composites Technology (ACT) Program. One of the expected milestones of the program is to develop standard test methods for these complex material systems. Current test methods for laminated composites may not be optimum for textile composites, since the architecture of the textile induces nonuniform deformation characteristics on the scale of the smallest repeating unit of the architecture. The smallest repeating unit, also called the unit cell, is often larger than the strain gages used for testing of tape composites. As a result, extending laminated composite test practices to textiles can often lead to pronounced scatter in material property measurements. It has been speculated that the fiber architectures produce significant surface strain nonuniformities, however, the magnitudes were not well understood. Moire interferometry, characterized by full-field information, high displacement sensitivity, and high spatial resolution, is well suited to document the surface strain on textile composites. Studies at the NASA Langley Research Center on a variety of textile architectures including 2-D braids and 3-D weaves, has evidenced the merits of using moire interferometry to guide in test method development for textile composites. Moire was used to support tensile testing by validating instrumentation practices and documenting damage mechanisms. It was used to validate shear test methods by mapping the full-field deformation of shear specimens. Moire was used to validate open hole tension experiments to determine the strain concentration and compare then to numeric predictions. It was used for through-the-thickness tensile strength test method development, to verify capabilities for testing of both 2-D and 3-D material systems. For all of these examples, moire interferometry provided vision so that test methods could be developed with less

    Moire interferometry is used to measure out-of-plane displacements with very high sensitivity. The experimental set-up is similar to that used for in-plane displacement measurement with a small modification. In the in-plane method, the deformed real specimen grating interferes with the fixed virtual reference grating to produce the moire fringes; while for the out-of-plane displacement method, the deformed virtual grating interferes with a real reference grating to produce the moire pattern.

    A shadow moire interferometry technique has been developed to measure residual strain in thin silicon sheet. The curvature of a segment of sheet undergoing four-point bending is analyzed to include the applied bending moments, the in-plane residual stresses, and the 'end effect' of the sheet since it is of finite length. The technique is applied to obtain residual stress distributions for silicon sheet grown by the edge-defined film-fed growth technique.

    Sensing characteristics of a precision aligner using moire gratings for precision alignment sysem has been investigated. A differential moire alignment system and a modified alignment system were used. The influence of the setting accuracy of the gap length and inclination of gratings on the alignment accuracy has been studied experimentally and theoretically. Setting accuracy of the gap length less than 2.5μm is required in modified moire alignment. There is no influence of the gap length on the alignment accuracy in the differential alignment system. The inclination affects alignment accuracies in both differential and modified moire alignment systems.

    Moire topography is applied to the figure assessment of solar mirrors. The technique is demonstrated on component facets of a six-meter diameter, four-meter focal length, parabolic dish collector. The relative ease of experimental implementation and subsequent data analysis suggests distinct advantages over the more established laser ray trace or BCS/ICS technique for many applications. The theoretical and experimental considerations necessary to fully implement moire topography on mirror surfaces are detailed. A procedure to de-specularize the mirror is demonstrated which conserves the surface morphology without damaging the reflective surface. The moire fringe patterns observed for the actual mirror facets are compared with theoretical contours generated for representative dish facets using a computer simulation algorithm. A method for evaluating the figure error of the real facet is presented in which the error parameter takes the form of an average absolute deviation of the surface slope from theoretical. The experimental measurement system used for this study employs a 200 line/inch Ronchi transmission grating. The mirror surface is illuminated by a collimated beam at 60/sup 0/. The fringe observation is performed normal to the grating. These parameters yield contour intervals for the fringe patterns of 0.073 mm. The practical considerations for extending the techniques to higher resolution are discussed.

    2009-01-01

    The hole-drilling method is one of the most well-known methods for measuring residual stresses. To identify unknown plane stresses in a specimen, a circular hole is first drilled in the infinite plate under plane stress, then the strains resulting from the hole drilling is measured. The strains may be acquired from interpreting the Moire signature around the hole. In crossed grating Moire interferometry, the horizontal and vertical displacement fields (u and v) can be obtained to determinate two strain fields and one sheafing strain field. In this paper, by means of Moire interferometry and three directions grating (grating rosette) developed by the authors, three displacement fields (u, v and s) are obtained to acquire three strain fields. As a practical application, the hole-drilling method is adopted to measure the relief strains for aluminum and fiber reinforced composite. It is a step by step method; in each step a single laminate or equivalent depth is drilled to find some relationships between the drilling depth and the residual strains relieved in the fiber reinforced composite materials.

    2017-05-23

    This work describes the measurement procedure and principles of a sampling moiré technique for full-field micro/nano-scale deformation measurements. The developed technique can be performed in two ways: using the reconstructed multiplication moiré method or the spatial phase-shifting sampling moiré method. When the specimen grid pitch is around 2 pixels, 2-pixel sampling moiré fringes are generated to reconstruct a multiplication moiré pattern for a deformation measurement. Both the displacement and strain sensitivities are twice as high as in the traditional scanning moiré method in the same wide field of view. When the specimen grid pitch is around or greater than 3 pixels, multi-pixel sampling moiré fringes are generated, and a spatial phase-shifting technique is combined for a full-field deformation measurement. The strain measurement accuracy is significantly improved, and automatic batch measurement is easily achievable. Both methods can measure the two-dimensional (2D) strain distributions from a single-shot grid image without rotating the specimen or scanning lines, as in traditional moiré techniques. As examples, the 2D displacement and strain distributions, including the shear strains of two carbon fiber-reinforced plastic specimens, were measured in three-point bending tests. The proposed technique is expected to play an important role in the non-destructive quantitative evaluations of mechanical properties, crack occurrences, and residual stresses of a variety of materials.

    2016-06-01

    An image converter tube with a magnetic lens was used to obtain static images of moiré fringes formed by electron beam. These moiré fringes are formed due to the interference between the anode mesh and the photocathode containing slits of various spatial frequencies. Moiré fringes are observed at an accelerating voltage of 3.5 kV requiring the magnetic excitation condition of ˜550 ampere-turns. Not only the features of the fringes are analyzed but also the change of fringe spacing as a function of the rotation angle is investigated. The experimental results are found well in agreement with the theoretical analysis. By changing the rotation angle or adjusting the excitation condition of the magnetic lens, we were able to record parallel moiré and secondary moiré fringes too. The secondary moiré fringes can be observed in the rotation angle range of -39.5° to -50.6°. The theoretical analysis indicates that the secondary moiré is formed by the interference between the photocathode slits and the 2-D periodic structure of the anode mesh. Combining our proposed moiré method with the pulse-dilation technique may potentially open the door for future applications, in various fields including, but not limited to, ultrafast electrical pulse diagnostics.

    A moiré pattern is observed by dividing the incident beam into two and formed by multiple Bragg–Laue interference fringes corresponding to the two incident beams. The coherency of X-rays from a bending-magnet beamline is evaluated using the moiré pattern. In X-ray section topography of Si 220 diffraction in a multiple Bragg–Laue mode, a moiré pattern is observed when the incident beam is divided into two parts by inserting a platinum wire in the middle of the beam. The moiré pattern can be explained by the summation of two interference fringes corresponding to the two incident beams. The coherency of the X-rays from the bending-magnet beamline is estimated using the moiré pattern.

    Full Text Available Three-way scanning electron microscope (SEM moiré was first generated using a designed three-way electron beam (EB in an SEM. The spot-type three-way SEM moiré comes from the interference between the three-way EB and the specimen grating in which the periodic cells are arranged in a triangular manner. The deformation and the structure information of the specimen grating in three directions can be simultaneously obtained from the three-way SEM moiré. The design considerations of the three-way EB were discussed. As an illustration, the three-way SEM moiré spots produced on a silicon slide were presented. The proposed three-way SEM moiré method is expected to characterize micro/nanostructures in triangular or hexagonal arrangements in three directions at the same time.

    In this paper, the optical/digital fringe multiplication (O/DFM) is realized in projection moiré using digital image processing (DIP). Both deformed grating and reference grating are captured using a CCD camera. The reference grating can also be produced using DIP. With the O/DFM, the pattern is multiplied with an image processing software, which is developed using MATLAB 6.5. Also with DIP, the phase shifting can become much simpler, and the automation can be adopted. The multiplied pattern is much thinner and easier to read, and sensitivity of measurement can be enhanced.

    Nowadays a major research issue of mobile robots is to develop a robust 3D environment sensing for navigation and task execution. To achieve this, a variety of techniques have been developed for the determination of the 3D scene geometric information such as stereo vision, laser structured light, laser range finder and so on. But these methods have many limitations. To overcome these limitations we introduce a new sensing algorithm, which is based on the moire technique and stereo vision. To verify the performance of this sensor system we conducted a series of simulation for various simple environments. The result shows the feasibility of successful perception with several environments.

    1991-04-01

    The techniques of high resolution moire photography and high speed photography have been combined to allow measurement of the in-plane components of a transient displacement field with microsecond time resolution. Specimen gratings are prepared as casts in a thin layer of epoxy resin on the surface of a specimen. These are illuminated with a flash tube and imaged onto a reference grating with a specially modified camera lens, which incorporates a slotted mask in the aperture plane. For specimen gratings of 75 lines mm1, this selects the +1 and -1 order diffracted beams, thus doubling the effective grating frequency to 150 lines mm1. The resulting real-time moire fringes are recorded with a Hadland 792 image converter camera (Imacon) at an inter-frame time of 2-5ts. The images are digitised and an automatic fringe analysis technique based on the 2-D Fourier transform method is used to extract the displacement information. The technique is illustrated by the results of an investigation into the transient deformation of composite disc specimens, impacted with rectangular metal sliders fired from a gas gun.

    This paper reports on a novel technique for measuring wafer warpage, using the design concepts of moiré shift, digital moiré, autocollimator, and the scanning profiling method. The measurement system is divided into two parts: an optical moiré system and a phase analysis system. The optical arrangement can be adjusted to control the projection of a linear grating image onto the surface of a wafer to be reflected back into a CCD camera. The grating image acquired by the CCD camera is used for measurement whereas a reference grating image is obtained using the digital moiré method. By overlapping the two images of the measurement and the reference gratings, the corresponding moiré fringes are formed. The phase of the moiré fringes will change proportionally to the degree of warpage in the wafer, which can be measured by detecting variations in the phase shift of the moiré fringes in the scanning profile across the surface of the entire wafer. Measurement resolution can be controlled by adjusting the pitch size of the grating or the focal length of the focusing lens, or by adjusting the angle between the images of the measurement and reference gratings. Experiment results demonstrate that the proposed method is able to achieve an angular resolution of 0.2 μrad. As compared to the current warpage measurement techniques, the proposed method has the ability of high measurement resolution, high stability, and high flexibility.

    Fleming, Gary A.; Bartram, Scott M.; Waszak, Martin R.; Jenkins, Luther N.

    2001-11-01

    Projection Moire Interferometry (PMI) has been used to measure the structural deformation of micro air vehicle (MAV) wings during a series of wind tunnel tests. The MAV wings had a highly flexible wing structure, generically reminiscent of a bat's wing, which resulted in significant changes in wing shape as a function of MAV angle-of-attack and simulated flight speed. This flow-adaptable wing deformation is thought to provide enhanced vehicle stability and wind gust alleviation compared to rigid wing designs. Investigation of the potential aerodynamic benefits of a flexible MAV wing required measurement of the wing shape under aerodynamic loads. PMI was used to quantify the aerodynamically induced changes in wing shape for three MAV wings having different structural designs and stiffness characteristics. This paper describes the PMI technique, its application to MAV testing, and presents a portion of the PMI data acquired for the three different MAV wings tested.

    2017-02-01

    In this work the influence of film-substrate misorientation on the strain-induced ordering of graphene films on various metallic surfaces is examined using a mesoscopic continuum model and first-principles atomistic calculations. The periodicity and free energy of the Moiré patterns that emerge are studied as a function of film-substrate adhesion strength for misfit strains far from and close to an incommensurate-commensurate phase transition. Interestingly the lowest energy states are found to be at small but finite misorientation even though these states have a higher domain wall density than the zero-misorientation states. First-principles density functional theory calculations are used to connect the results with experimental findings in graphene epitaxy. This combination of mesoscopic and atomistic approaches can be applied to the study of a wide range of strained 2D material systems including the III-nitride monolayer systems.

Micro holes and lines are firstly etched for parameter study. Grating profile is theoretically optimized to form high quality moiré patterns. For a demonstration, a parallel grating is fabricated on a specimen of quartz glass. The minimum line width and the distance between two adjacent lines are both set to be 1μm, and the frequency of grating is 500lines/mm. The experimental results indicate that the quality of gratings is good and the relative error of the gratings pitch is about 1.5%. Based on moiré method, scanning electron microscope (SEM moiré patterns are observed clearly, which manifests that gratings fabricated with the femtosecond laser exposure is suitable for micro scale deformation measurement.

  19. Projection of phase singularities in moiré fringe onto a light field

    Science.gov (United States)

    Ohno, Seigo

    2016-06-01

    A moiré pattern, which is a kind of spatial interference between two periodic patterns, is regarded as a spatial modulation of a "field." By defining the displacement field, we reveal that moiré patterns can have a topological phase singularity, similar to a disclination in liquid crystal and, more generally, a vector field treated in the singular optics. We propose that topological singularities in the moiré displacement field can be projected by passing an electromagnetic field through a metasurface. We designed a metasurface constructed from two layers of a metal disk array operating in the terahertz band; then we numerically estimated the spatial distribution of its transmission properties. The phase singularities in the electromagnetic fields coincided with the singularities appearing in the moiré pattern. We found two kinds of singularities, and the phase of the electromagnetic field changed by 2π or 4π around them. These phase changes were independent of the light frequency, implying that the topological properties of the moiré fields were projected onto the electromagnetic field. This feature of moiré metasurfaces can potentially be exploited in spiral phase plate arrays with no frequency dispersion of the phase change.

    A digital nano-moire method with wavelet transformation is explored to measure nanoscale in-plane displacement fields. By applying e-beam lithography, a periodic PMMA nanostructure array is fabricated directly on the specimen and used as the specimen grating. Moire patterns are generated by overlapping the images of the PMMA specimen grating obtained from AFM scanning and the virtual reference grating produced by a digital image generating process. Then, the overlapped images are filtered by the 2D wavelet transformation (WT) to capture the target moire patterns. Existing methods, by overlapping the monitor-generated scanning lines with the image of the specimen grating, cause a mismatch problem. Previously, the carrier moire method was explored with the aim of curing the mismatch problem. Unfortunately, the carrier moire method, in addition to suffering from increased complexity of mathematical calculations, is incapable of directly obtaining the displacement field. Thus, the mismatch problem will result in inconveniences and restrictions in the practical application. Instead of using monitor-generated scanning lines, the proposed method applies the virtual reference grating, and thus puts the mismatch problem to rest. Nevertheless, the resultant moire image suffers from low contrast which, if left untreated, might distort the measurement result. Therefore, the WT, known for its sharpened abilities of characteristic and edge detection, is used to capture the target moire patterns and improve the measurement accuracy. The proposed method has been carried out in the laboratory. Experimental results have shown that the proposed method is convenient and efficient for nanoscale displacement measurement.

    In this paper, the application of "parallel" moiré deflectometry in measuring the nonlinear refractive index of materials is reported. In "parallel" moiré deflectometry the grating vectors are parallel, and the resulting moiré fringes are also parallel to the grating lines. Compared to "rotational" moiré deflectometry and the Z-scan technique, which cannot easily determine the moiré fringe's angle of rotation and is sensitive to power fluctuations, respectively, "parallel" moiré deflectometry is more reliable, which allows one to measure the radius of curvature of the light beam by measuring the moiré fringe spacing. The nonlinear refractive index of the sample, including the sense of the change, is obtained from the moiré fringe spacing curve. The method is applied for measuring the nonlinear refractive index of ferrofluids.

    A new electron interferometry method has been developed and implemented in a transmission electron microscope to quantitatively analyse magnetic and electric properties emanating from objects using holograms free of artifacts and with a frequential sensitivity. This method, called dynamical holographic Moirés (DHM), is based on the double-exposure technique consisting in the superimposition of two different holograms. We improved this technique by acquiring the superimposed holograms for two well-defined excitation states of the sample and with a control of the superimposition frequency. The variations of magnetic and electrostatic fields between both excitation states can then be extracted directly from the amplitude part of the so-called interferogram. We demonstrate the efficiency of this method by studying quantitatively the magnetic field generated by a hard disk drive writing head excited by a DC and an AC current. Double exposure measurements have also been performed to study in situ electrostatic properties of a biased carbon nanocone tip. Our method opens the route to dynamical studies using the unique combination of nanoscale resolution and electromagnetic sensitivity of electron interferometry.

    We report on strategies for characterizing hexagonal coincidence phases by analyzing the involved spatial moiré beating frequencies of the pattern. We derive general properties of the moiré regarding its symmetry and construct the spatial beating frequency {K}\\text{moir{\\'e}} as the difference between two reciprocal lattice vectors {k}i of the two coinciding lattices. Considering reciprocal lattice vectors {k}{i}, with lengths of up to n times the respective (1, 0) beams of the two lattices, readily increases the number of beating frequencies of the nth-order moiré pattern. We predict how many beating frequencies occur in nth-order moirés and show that for one hexagonal lattice rotating above another the involved beating frequencies follow circular trajectories in reciprocal-space. The radius and lateral displacement of such circles are defined by the order n and the ratio x of the two lattice constants. The question of whether the moiré pattern is commensurate or not is addressed by using our derived concept of commensurability plots. When searching potential commensurate phases we introduce a method, which we call cell augmentation, and which avoids the need to consider high-order beating frequencies as discussed using the reported (6\\sqrt{3}× 6\\sqrt{3}){R}{30^\\circ } moiré of graphene on SiC(0001). We also show how to apply our model for the characterization of hexagonal moiré phases, found for transition metal-supported graphene and related systems. We explicitly treat surface x-ray diffraction-, scanning tunneling microscopy- and low-energy electron diffraction data to extract the unit cell of commensurate phases or to find evidence for incommensurability. For each data type, analysis strategies are outlined and avoidable pitfalls are discussed. We also point out the close relation of spatial beating frequencies in a moiré and multiple scattering in electron diffraction data and show how this fact can be explicitly used to extract high

    Moire interferometry is an interferometric method for measuring changes of in-plane geometry. It is essentially insensitive to out-of-plane topography or changes in that topography. Changes in geometry are referenced to a particular moment in time when the moire` sensor, a diffraction grating, was attached to the specimen. Distortions experienced by the specimen prior to that time are not directly detectable, although they may be inferred from specimen behavior or condition. In its most common form, moire interferometry is not well suited to large (> 50 mm square), curved (< 300 mm diameter) or high temperature (> 200 C) regions. However, various efforts have been made to handle each of these conditions. In general, the moire` process is most straightforward for flat, 25 mm diameter regions of coverage and room temperature. Much smaller or larger regions require more specialized optics, which can become very expensive. This report will discuss various aspects of moire interferometry. In particular, a new four beam (bi-axial) interferometer is described in detail. Issues involved in safety, assembly, calibration and use are fully explained.

    2016-11-01

    A single-frame grid-noise removal technique was developed for application in single-frame digital-moiré 3D shape measurement. The ability of the stationary wavelet transform (SWT) to prevent oscillation artifacts near discontinuities, and the ability of the Fourier transform (FFT) applied to wavelet coefficients to separate grid-noise from useful image information, were combined in a new technique, SWT-FFT, to remove grid-noise from moiré-pattern images generated by digital moiré. In comparison to previous grid-noise removal techniques in moiré, SWT-FFT avoids the requirement for mechanical translation of optical components and capture of multiple frames, to enable single-frame moiré-based measurement. Experiments using FFT, Discrete Wavelet Transform (DWT), DWT-FFT, and SWT-FFT were performed on moiré-pattern images containing grid noise, generated by digital moiré, for several test objects. SWT-FFT had the best performance in removing high-frequency grid-noise, both straight and curved lines, minimizing artifacts, and preserving the moiré pattern without blurring and degradation. SWT-FFT also had the lowest noise amplitude in the reconstructed height and lowest roughness index for all test objects, indicating best grid-noise removal in comparison to the other techniques.

    Using experimental mechanics method of moiré analysis, strain field distributions of 2024 aluminum alloy welded joints under different conditions were investigated. The results show that moiré stripes of welded joint without trailing peening just before fracture are not only few and scattered but also uneven, and the stress mainly concentrates on the poor position-welded toes during the tensioning process with the relatively poor mechanical properties of welded joints; When the method of welding with trailing peening is adopted, moiré stripes of welded joint just before fracture are relatively thick and even due to the strengthening welded toes during the welding process, and fracture position transfers from the welded toes to weld, at the same time the mechanical properties of welded joints are improved greatly than conventional welding which can show that the technology of trailing peening is effective to strengthen welded joints of aluminum alloy with high strength.

    In this paper we present a method for determining the preferred slanted angle for a lenticular film that minimizes moiré patterns in quasi-three-dimensional (Q3D) displays. We evaluate the preferred slanted angles of the lenticular film for the stripe-type sub-pixel structure liquid crystal display (LCD) panel. Additionally, the sub-pixels mapping algorithm of the specific angle is proposed to assign the images to either the right or left eye channel. A Q3D display prototype is built. Compared with the conventional SLF, this newly implemented Q3D display can not only eliminate moiré patterns but also provide 3D images in both portrait and landscape orientations. It is demonstrated that the developed slanted lenticular film (SLF) provides satisfactory 3D images by employing a compact structure, minimum moiré patterns and stabilized 3D contrast.

    Full Text Available Development and optimization of projects for agricultural machinery involve the analysis of stress and strain. Moiré photomechanical techniques provide a complete displacement field of the specimen under test, and can aid in understanding the mechanical behavior of parts with complex geometry. Hybrid methods combine fringe patterns of displacement with distribution maps of stress and strain through concepts of the theory of elasticity. The objective of this work was to analyse the use of the shadow moiré technique in the qualitative determination of stress and strain distribution in geometrically complex machine elements. The results were compared with those from an electrical extensometer and a computer simulation. The results demonstrated that the shadow moire technique was quite reliable in analysing the mechanical behavior of geometrically complex machine elements.

    This report describes the employment of moiré patterns to model visually interference phenomena in general and laser Doppler anemometer signals in particular. The modeling includes signals created in dual beam and reference beam anemometers by both single particles and particle pairs. The considerations are extended to visual modeling of multiparticle signals and the decay of signal quality in the presence of many particles. The fringe model of the laser Doppler anemometer is also considered, and moiré patterns are employed to demonstrate the interference fringes in the crossover region of two intersecting laser beams. Gaussian beam properties are taken into account to allow the effects of improperly designed optical systems to be studied. Instructions for using computer generated transparencies to produce the different moiré patterns are provided to allow the reader to study in detail the various interference phenomena described.

  11. Moiré scaling of the sliding force in twisted bilayer graphene

    2016-07-01

    The weak interlayer binding in two-dimensional layered materials such as graphite gives rise to distinguished low-friction properties if the atomic lattices at the interface are rotated with respect to one another. The lack of crystal symmetry leads to poorly understood correlations and cancelations of the interlayer atomic forces. Here we report on a powerful tiling method based on the moiré superstructure which allows us to study the intricate interplay of the interlayer forces in a systematic manner. Based on numerical simulation data for a circular graphene flake on an infinite graphene substrate, it is shown that the sliding force is dominated by a rim area consisting of incomplete moiré tiles. This rim force, which scales with the number of atoms in a moiré tile and as the radius to the power of 0.5, is minimal whenever the sliding structure can be approximated by a hexagon composed of an integer number Nt of moiré tiles. Intriguingly, the corresponding area force scales as Nt to the power of 0.25, i.e., it increases with size, whereas it has been often argued that interlayer forces should add up to a zero value for large twisted systems. However, at specific twist angles the moiré structure is commensurate with the graphene lattice, leading to a perfect force correlation in the moiré tiles. Correspondingly, the area force becomes dominant and scales as Nt, i.e., as the radius to the power of 2.

    Chen, Xinxing; Chang, Chih-Chen

    2016-04-01

    Digital sampling moiré (DSM) method is a newly developed vision-based technique that uses the phase information of moiré fringes to measure movement of an object. The moiré fringes are generated from a sequence of digital images, containing a cosinusoidal grating pattern attached to the object, through down-sampling and interpolation. As the moiré fringes can magnify the pattern's movement, this technique is expected to provide more accurate displacement measurement than the other vision based approaches. In this study, a method combining DSM with monocular videogrammetric technique is proposed to measure in-plane rotation and translation of structures. In this method, images of a two-dimensional (2D) grating pattern attached to a moving structure are acquired and decomposed into two perpendicular gratings through Fourier transform. The DSM method is used to obtain 2D phase distributions of the gratings which provide an estimation of physical coordinates for those points on the grating pattern. A previously developed monocular videogrammetric technique can then be used to obtain the rotation angle and the translation of the grating pattern. The proposed method is validated using both numerical simulation and laboratory tests.

    2016-05-01

    Two-dimensional (2D) van der Waals (vdW) superstructures, or vdW solids, are formed by the precise restacking of 2D nanosheet lattices, which can lead to unique physical and electronic properties that are not available in the parent nanosheets. Moiré patterns formed by the crystalline mismatch between adjacent nanosheets are the most direct features for vdW superstructures under microscopic imaging. In this article, transmission electron microscopy (TEM) observation of hexagonal Moiré patterns with unusually large micrometer-sized lateral areas (up to ~1 μm2) and periodicities (up to ~50 nm) from restacking of liquid exfoliated hexagonal boron nitride nanosheets (BNNSs) is reported. This observation was attributed to the long range crystallinity and the contaminant-free surfaces of these chemically inert nanosheets. Parallel-line-like Moiré fringes with similarly large periodicities were also observed. The simulations and experiments unambiguously revealed that the hexagonal patterns and the parallel fringes originated from the same rotationally mismatched vdW stacking of BNNSs and can be inter-converted by simply tilting the TEM specimen following designated directions. This finding may pave the way for further structural decoding of other 2D vdW superstructure systems with more complex Moiré images.

    Measuring static and dynamic displacements for in-service structures is an important issue for the purpose of design validation, performance monitoring and safety assessment of structures. Currently available techniques can be classified into indirect measurement and direct measurement. These methods however have their own problems and limitations Digital sampling moiré method is a newly developed vision-based technique for direct displacement measurement. It uses one camera to capture digital images containing a grating pattern. The images are subsampled and interpolated to generate moiré patterns whose phase information can then be used to calculate displacements of the grating pattern. As the moiré patterns can magnify the pattern's movement, this technique is expected to provide more accurate displacement measurement than the other vision based approaches. In this study, a digital sampling moiré technique is proposed for measuring two-dimensional structural displacements using a designed grating pattern. The pattern contains two orthogonally inclined gratings and does not have to be perfectly aligned with the image plane. A series of simulation and laboratory tests are conducted to validate the accuracy of the proposed technique. Results show that the technique can achieve accuracy in the order of 10 micrometers in the laboratory. Also, the technique does not seem to suffer from the issue of misalignment between the camera and the pattern and exhibits a potential for accurate measurement of displacement for civil engineering structures.

    2017-01-01

    This article shows the presence of Moiré Interference patterns in the map of periods of the Mandelbrot Set. It describes the requirements for their appearance and shows that such interferences are highly sensitive to the original conditions that define their calculation. The specific case herein studied shows that the Moiré interference patterns appearing in a picture of a section of the map of orbits are unpredictable, even if we obtain different maps from very similar original conditions. It begins with a brief description of the Mandelbrot Set and some of the characteristics of its orbits, the Moiré Patterns, as well as a concise introduction to a description of the Discrete Wavelet Transform. In order to develop the proposed specific case, a Multi-resolution Analysis method based on the Discrete Wavelet Transform has been used. It is significant that Moiré Interference Patterns always appear when the order of magnitudes reaches a certain limit where, what is considered as hypothetically continuous, behaves as a discrete pattern. The patterns as shown by the Wavelet analysis change drastically at the slightest modification in the original calculation conditions and it does not seem possible to predict their shape beforehand. This article ends with some conclusions and suggestions.

    Aimed at the low accuracy problem of shear strain measurement in Moiré methods, a two-dimensional (2D) Moiré phase analysis method is proposed for full-field deformation measurement with high accuracy. A grid image is first processed by the spatial phase-shifting sampling Moiré technique to get the Moiré phases in two directions, which are then conjointly analyzed for measuring 2D displacement and strain distributions. The strain especially the shear strain measurement accuracy is remarkably improved, and dynamic deformation is measurable from automatic batch processing of single-shot grid images. As an application, the 2D microscale strain distributions of a titanium alloy were measured, and the crack occurrence location was successfully predicted from strain concentration.

    Image steganography technique is widely used to realize the secrecy transmission. Although its strategies on classical computers have been extensively researched, there are few studies on such strategies on quantum computers. Therefore, in this paper, a novel, secure and keyless steganography approach for images on quantum computers is proposed based on Moiré pattern. Algorithms based on the Moiré pattern are proposed for binary image embedding and extraction. Based on the novel enhanced quantum representation of digital images (NEQR), recursive and progressively layered quantum circuits for embedding and extraction operations are designed. In the end, experiments are done to verify the validity and robustness of proposed methods, which confirms that the approach in this paper is effective in quantum image steganography strategy.

    The development of techniques for the health monitoring of the rotating components in gas turbine engines is of major interest to NASA s Aviation Safety Program. As part of this on-going effort several experiments utilizing a novel optical Moir based concept along with external blade tip clearance and shaft displacement instrumentation were conducted on a simulated turbine engine disk as a means of demonstrating a potential optical crack detection technique. A Moir pattern results from the overlap of two repetitive patterns with slightly different periods. With this technique, it is possible to detect very small differences in spacing and hence radial growth in a rotating disk due to a flaw such as a crack. The experiment involved etching a circular reference pattern on a subscale engine disk that had a 50.8 mm (2 in.) long notch machined into it to simulate a crack. The disk was operated at speeds up to 12 000 rpm and the Moir pattern due to the shift with respect to the reference pattern was monitored as a means of detecting the radial growth of the disk due to the defect. In addition, blade displacement data were acquired using external blade tip clearance and shaft displacement sensors as a means of confirming the data obtained from the optical technique. The results of the crack detection experiments and its associated analysis are presented in this paper.

    Self-assembly of atoms or molecules on a crystal surface is considered one of the most promising methods to create molecular devices. Here we report a stepwise self-assembly of C₆₀ molecules into islands with unusual shapes and preferred sizes on a gold-indium-covered Si(111) surface. Specifically, 19-mer islands prefer a non-compact boomerang shape, whereas hexagonal 37-mer islands exhibit extraordinarily enhanced stability and abundance. The stepwise self-assembly is mediated by the moiré interference between an island with its underlying lattice, which essentially maps out the adsorption-energy landscape of a C₆₀ on different positions of the surface with a lateral magnification factor and dictates the probability for the subsequent attachment of C₆₀ to an island's periphery. Our discovery suggests a new method for exploiting the moiré interference to dynamically assist the self-assembly of particles and provides an unexplored tactic of engineering atomic scale moiré magnifiers to facilitate the growth of monodispersed mesoscopic structures.

    The multi-lateral shearing interferometers (multi-LSIs) are featured in the improved accuracy and noise resistance of wavefront reconstruction using phase differences in multiple directions. Nowadays the multidirectional phase differences are usually extracted from multi-LSIs' interferogram using the fast Fourier transform (FFT) method, whose accuracy is limited by spectral leakage effect. To improve the measurement accuracy of multi-LSIs, a phase extraction method developed from moiré technique is proposed in this paper. Using virtual gratings with properly large carrier frequencies, the desired phase information in each of the multiple directions can be modulated into low-frequency domain of the corresponding moiré pattern with larger separations between unnecessary side lobes. In this way, low-pass filters with higher cut-off frequencies can be applied in moiré technique to reduce the inaccuracy induced by spectral leakage effect. Meanwhile, phase shifting method can be applied to extract phase information from a single fringe pattern with better noise resistance by easily introducing phase shifts in computer generated virtual gratings. Simulation results show that the proposed method has higher accuracy and better anti-noise performance than the FFT method when spectral leakage effect exists. To demonstrate accuracy of the proposed method, a null test experiment of the quadriwave LSI has been conducted and experimental results show that measurement accuracy of the quadriwave LSI can be significantly improved by substituting the FFT method with the proposed method in phase extraction process.

    Capacitive touch sensor screen with the metal materials has recently become qualified for substitution of ITO; however several obstacles still have to be solved. One of the most important issues is moiré phenomenon. The visibility problem of the metal-mesh, in touch sensor module (TSM) is numerically considered in this paper. Based on human eye contract sensitivity function (CSF), moiré pattern of TSM electrode mesh structure is simulated with MATLAB software for 8 inch screen display in oblique view. Standard deviation of the generated moiré by the superposition of electrode mesh and screen image is calculated to find the optimal parameters which provide the minimum moiré visibility. To create the screen pixel array and mesh electrode, rectangular function is used. The filtered image, in frequency domain, is obtained by multiplication of Fourier transform of the finite mesh pattern (product of screen pixel and mesh electrode) with the calculated CSF function for three different observer distances (L=200, 300 and 400 mm). It is observed that the discrepancy between analytical and numerical results is less than 0.6% for 400 mm viewer distance. Moreover, in the case of oblique view due to considering the thickness of the finite film between mesh electrodes and screen, different points of minimum standard deviation of moiré pattern are predicted compared to normal view.

    2012-06-01

    Recently, a rapid and accurate single-shot phase measurement technique called the sampling moiré method has been developed for small-displacement distribution measurements. In this study, the theoretical phase error of the sampling moiré method caused by linear intensity interpolation in the case of a mismatch between the sampling pitch and the original grating pitch is analyzed. The periodic phase error is proportional to the square of the spatial angular frequency of the moiré fringe. Moreover, an effective phase compensation methodology is developed to reduce the periodic phase error. Single-shot phase analysis can perform accurately even when the sampling pitch is not matched to the original grating pitch exactly. The primary simulation results demonstrate the effectiveness of the proposed phase compensation methodology.

    Moiré pattern noise in Scanning Transmission X-ray Microscopy (STXM) imaging introduces significant errors in qualitative and quantitative image analysis. Due to the complex origin of the noise, it is difficult to avoid Moiré pattern noise during the image data acquisition stage. In this paper, we introduce a post-processing method for filtering Moiré pattern noise from STXM images. This method includes a semi-automatic detection of the spectral peaks in the Fourier amplitude spectrum by using a local median filter, and elimination of the spectral noise peaks using a Gaussian notch filter. The proposed median-Gaussian filtering framework shows good results for STXM images with the size of power of two, if such parameters as threshold, sizes of the median and Gaussian filters, and size of the low frequency window, have been properly selected.

Dans ce texte, nous nous attelons à tracer l’histoire de la mémoire des disparus politiques dans l’arène publique en Uruguay pour connaître les motifs qu’ont faits des disparus de l’image du passé récent.Discussions on violence during the years 1960-1980 in South America have for some time been a central issue in the public space of many South American countries. Uruguay, having gone through a strongly repressive civic-military regime between 1973 and 1985, was no exception. While public memories on this period have gone through different phases, the forced disappearances have always been the main focus of the struggles for memory. This article attempts to trace the history of the remembering of these victims of forced disappearance in the Uruguayan public arena in order to determine memory patterns in the image of a recent past.

    The mapping of traction forces is crucial to understanding the means by which cells regulate their behavior and physiological function to adapt to and communicate with their local microenvironment. To this end, polymeric micropillar arrays have been used for measuring cell traction force. However, the small scale of the micropillar deflections induced by cell traction forces results in highly inefficient force analyses using conventional optical approaches; in many cases, cell forces may be below the limits of detection achieved using conventional microscopy. To address these limitations, the moiré phenomenon has been leveraged as a visualization tool for cell force mapping due to its inherent magnification effect and capacity for whole-field force measurements. This Letter reports an optomechanical cell force sensor, namely, a double-sided micropillar array (DMPA) made of poly(dimethylsiloxane), on which one side is employed to support cultured living cells while the opposing side serves as a reference pattern for generating moiré patterns. The distance between the two sides, which is a crucial parameter influencing moiré pattern contrast, is predetermined during fabrication using theoretical calculations based on the Talbot effect that aim to optimize contrast. Herein, double-sided micropillar arrays were validated by mapping mouse embryo fibroblast contraction forces and the resulting force maps compared to conventional microscopy image analyses as the reference standard. The DMPA-based approach precludes the requirement for aligning two independent periodic substrates, improves moiré contrast, and enables efficient moiré pattern generation. Furthermore, the double-sided structure readily allows for the integration of moiré-based cell force mapping into microfabricated cell culture environments or lab-on-a-chip devices.

    In view of the progress on the confinement of light, we report on the dispersion characteristics of surface plasmon polaritons (SPPs) on two-dimensional Moiré surfaces in the visible part of the electromagnetic spectrum. Polarization dependent spectroscopic reflection measurements show omnidirectional confinement of SPPs. The resonance wavelength of SPP cavity modes can be adjusted by tuning the propagation direction of SPPs. The results may have an impact on the control of spontaneous emission and absorption with applications in light emitting diodes and solar cells, as well as in quantum electrodynamics experiments.

  14. Strain analysis of a bonded, dissimilar, composite material T-joint using moiré interferometry

    Science.gov (United States)

    Gascoigne, H. E.; Abdallah, M. G.

    High-sensitivity moiré interferometry and finite-element analysis are used to analyze the state of deformation and stress in the region of contact between a plane orthotropic rectangular punch bonded to a foundation with dissimilar elastic properties which models a highly loaded region of a composite material rocket motor casing. Stress distributions are presented for the contact region and an estimate of the maximum shear stress in the foundation is given. The displacement components show good qualitative agreement between analysis and experiment. The lack of quantitative agreement between the experimental and the finite-element analysis is attributed to uncertainty of the material properties.

    An instrument development program aimed at using Projection Moire Interferometry (PMI) for acquiring model deformation measurements in large wind tunnels was begun at NASA Langley Research Center in 1996. Various improvements to the initial prototype PMI systems have been made throughout this development effort. This paper documents several of the most significant improvements to the optical hardware and image processing software, and addresses system implementation issues for large wind tunnel applications. The improvements have increased both measurement accuracy and instrument efficiency, promoting the routine use of PMI for model deformation measurements in production wind tunnel tests.

    We propose and demonstrate trapping and rotation of microparticles and biological samples with a moiré-based rotating optical tweezers. We show that polystyrene beads, as well as Escherichia coli cells, can be rotated with ease, while the speed and direction of rotation are fully controllable by a computer, obviating mechanical movement or phase-sensitive interference. Furthermore, we demonstrate experimentally the generation of white-light propelling beams and arrays, and discuss the possibility of optical tweezing and particle micro-manipulation based on incoherent white-light rotating patterns.

    This study constructed a measurement system that can quickly and accurately analyze the residual stress of flexible electronics. A double beam shadow moiré interferometer was set up to measure and evaluate the residual stress of tin-doped indium oxide films on a polyethylene terephthalate substrate. However, this system required only two symmetrical fringes to evaluate the residual stress of transparent conductive oxide films on flexible substrate. Applying the grating translation techniques to the double beam shadow moiré interferometer greatly improved the measurement resolution and accuracy, and the relative error was reduced to 1.2%.

    Full Text Available Scanning moiré fringe (SMF imaging by high-angle annular dark field scanning transmission electron microscopy was used to measure the strain field in the channel of a transistor with a CoSi2 source and drain. Nanometer-scale SMFs were formed with a scanning grating size of ds at integer multiples of the Si crystal lattice spacing dl (ds ∼ ndl, n = 2, 3, 4, 5. The moiré fringe formula was modified to establish a method for quantifying strain measurement. We showed that strain fields in a transistor measured by SMF images were reproducible with an accuracy of 0.02%.

    The application of geometric moiré in large deformation of 3-D models is discussed. Different aspects of the method, such as mismatch technique and mechanical differentiation, are taken into consideration for the measurement. An application of the method is given to the cushion disk of an artificial knee joint in whose axis-symmetric cross section a cross specimen grating of 0.5mm pitch was replicated. The analysis shows the applicability of the geometric moiré, together with its various approaches, in the large deformation measurement giving the whole field quantitative definition.

    A new contact-free approach for measuring simultaneously electric and magnetic field is reported, which considers the use of a low energy ion source, a set of three transmission gratings and a position sensitive detector. Recently tested with antiprotons (Aghion et al., 2014) [1] at the CERN Antiproton Decelerator facility, this paper extends the proof of principle of a moiré deflectometer (Oberthaler et al., 1996) [2] for distinguishing electric from magnetic fields and opens the route to precision measurements when one is not limited by the ion source intensity. The apparatus presented, whose resolution is mainly limited by the shot noise is able to measure fields as low as 9 mVm−1 Hz−1/2 for electric component and 100 μG Hz−1/2 for the magnetic component. Scaled to 100 nm pitch for the gratings, accessible with current state-of-the-art technology [3], the moiré fieldmeter would be able to measure fields as low as 22 μVm−1 Hz−1/2 and 0.2 μG Hz−1/2.

    Recently proposed mechanism for self-organized formation of magic islands [Nat.Comm. 4(2013)1679] has received a new experimental confirmation. According to this mechanism, self-assembly is mediated by the moiré interference between an island and underlying substrate lattice. It was first detected at C60 island growth on In-adsorbed Si(111)√{ 3} ×√{ 3}-Au surface. Changing In adsorbate for Tl results in lowering the corrugations of the surface potential relief due to a greater surface metallization. This allows formation of the C60 arrays with novel moiré pattern. As a result, a new set of magic C60 islands is formed on Tl-adsorbed Au/Si(111) surface differing from that observed on In-adsorbed surface. For example, the 19-C60 magic island which has a non-compact boomerang shape on In-adsorbed Au/Si(111) surfaces adopts a shape of a regular hexagon on Tl-adsorbed surface.

    This research aims to understand the reliability of Sn-Ag-Cu solder interconnects used in plastic ball grid array (PBGA) packages using microstructure evolution, laser moire interferometry and finite-element modeling. A particle coarsening based microstructure evolution of the solder joint material during thermal excursions was studied for extended periods of time lasting for several months. The microstructure evolution and particle coarsening was quantified, and acceleration factors were determined between benign field-use conditions and accelerated thermal cycling (ATC) conditions for PBGA packages with different form factors and for two different lead-free solder alloys. A new technique using laser moire interferometry was developed to assess the deformation behavior of Sn-Ag-Cu based solder joints during thermal excursions. This technique can used to estimate the fatigue life of solder joints quickly in a matter of few days instead of months and can be extended to cover a wide range of temperature regimes. Finite-element analysis (FEA) in conjunction with experimental data from the ATC for different lead-free PBGA packages was used to develop a fatigue life model that can be used to predict solder joint fatigue life for any PBGA package. The proposed model will be able to predict the mean number of cycles required for crack initiation and crack growth rate in a solder joint.

    In this paper, residual stresses of the Ni-Cr-B-Si coatings prepared by supersonic plasma spray processing were measured by moiré interferometry and X-ray diffraction method. Moiré interferometry method was used in measuring the distribution of residual stresses of the Ni-Cr-B-Si coatings alongside the specimen thickness direction, then the distribution of residual stresses both in the substrate and the coating was also analyzed. Experimental results showed that residual stresses in the coating and the substrate are tensile and compressive separately; residual stresses of the coating are diminished with the increase of the distance from the coating surface and almost zero at the coating-substrate interface; the maximum of compressive residual stresses of the substrate are present to the vicinity of the coating-substrate interface. It could be concluded that residual stresses in the specimen would result from the dismatch of thermophysical properties between the coating and substrate during the spray process, and the distribution of residual stresses of the substrate would be influenced by the sandblasting prior to spraying.

A luz que passa entre os retículos se sobrepõe formando padrões de moiré ou franjas de moiré que se comportam como ondas senoidais. Nos ensaios de calibração, usou-se um cone de relevo conhecido para a determinação de uma constante de correção de mapas gerados digitalmente. Os ensaios realizados aplicaram a metodologia para a determinação do perfil de um mouse de computador e para a determinação da deformação de uma chapa metálica.

    Full Text Available Projection Moiré Interferometry (PMI has been used to obtain near instantaneous, quantitative blade deformation measurements of a generic rotorcraft model at several test conditions. These laser-based measurements provide quantitative, whole field, dynamic blade deformation profiles conditionally sampled as a function of rotor azimuth. The instantaneous nature of the measurements permits computation of the mean and unsteady blade deformation, blade bending, and twist. The PMI method is presented, and the image processing steps required to obtain quantitative deformation profiles from PMI interferograms are described. Experimental results are provided which show blade bending, twist, and unsteady motion. This initial proof-of-concept test has demonstrated the capability of PMI to acquire accurate, full field rotorcraft blade deformation data.

    In an influential paper Jamshidi-Ghaleh and Mansour [1] (Opt. Commun. 234 (2004) 419), have reported on a new method for measuring the nonlinear refractive index of materials using the rotational moiré deflectometry technique. In the cited work, the authors apply the ray matrix theory for finding the beam deflection angle on the plane of the first grating in the used geometry. To this end, using the parabolic approximation, the exponential term in the beam irradiance is expanded and retaining the first two resultant terms, the nonlinear sample is treated as a thin lens with a position dependent focal length. In this comment, the effective focal length of the nonlinear sample has been rederived in detail using the Gaussian beam theory and it is shown that it must contain a correction factor. The relative error introduced by ignoring this factor can be as large as 73.5-84.4% in determining the nonlinear refractive index of thin samples.

Politique : un type de remémoration doit être mis à profit par cette image pour le progrès de la civilisation, notamment contre le fascisme. Au terme de ce cheminement, apparaît le rôle décisif de la métathéorie pour la théorie qui fait voir la différence profonde entre nos deux auteurs que le combat épistémologique qu’il entraînait avait rapprochés.

  15. Virtual fields method coupled with moiré interferometry: Special considerations and application

    Science.gov (United States)

    Zhou, Mengmeng; Xie, Huimin; Wu, Lifu

    2016-12-01

    The virtual fields method (VFM) is a novel highly efficient non-iterative tool for the identification of the constitutive parameters of materials. The VFM can obtain several constitutive parameters based on the full-field deformation of the specimen measured in a single test. However, the available results demonstrate that the accuracy of the identification result is strongly dependent on the quality of the deformation field, which is generally measured using optical methods. Especially, in the case where a small deformation is applied under elastic loading, the image noise and measurement error will exhibit a significant influence on the identification results. By combining the VFM with moiré interferometry (MI), a MI-based VFM is used to identify the parameters of an orthotropic linear elastic material. A numerical experiment is conducted to examine the feasibility of this method. From the analysis results, we determine that two factors exhibit an influence on the identification accuracy. The reinforcement direction of the orthotropic material is one factor, and the other is the noise in the deformation field. This MI-based VFM is then applied to determine the mechanical parameters of a unidirectional carbon fiber composite material. In the measurement, a three-point bending load is applied to the specimens. A high density grating with a frequency of 1200 line/mm grating is replicated on the specimen surface and used for measuring the in-plane deformation fields using a moiré interferometer. The obtained deformation fields are taken as the inputs of the VFM identification process, and the elastic properties of the materials are identified. The obtained results verify the advantage of the proposed method with respect to high accuracy and good noise immunity.

  19. Cross-Sectional Residual Stresses in Thermal Spray Coatings Measured by Moiré Interferometry and Nanoindentation Technique

    2012-09-01

    A plasma-sprayed thermal barrier coating (TBC) was deposited on a stainless steel substrate. The residual stresses were firstly measured by moiré interferometry combined with a cutting relaxation method. The fringe patterns in the cross-section of the specimen clearly demonstrate the deformation caused by the residual stress in thermal spray coatings. However, restricted by the sensitivity of moiré interferometry, there are few fringes in the top coat, and large errors may exist in evaluating the residual stress in the top coat. Then, the nanoindentation technique was used to estimate the residual stresses across the coating thickness. The stress/depth profile shows that the process-induced stresses after thermal spray are compressive in the top coat and a tendency to a more compressive state toward the interface. In addition, the stress gradient in the substrate is nonlinear, and tensile and compressive stresses appear simultaneously for self-equilibrium in the cross-section.

    Periodic clustered-dot screens are widely used for electrophotographic printers due to their print stability. However, moiré is a ubiquitous problem that arises in color printing due to the beating together of the clustered-dot, periodic halftone patterns that are used to represent different colorants. The traditional solution in the graphic arts and printing industry is to rotate identical square screens to angles that are maximally separated from each other. However, the effectiveness of this approach is limited when printing with more than four colorants, i.e., N -color printing, where N > 4 . Moreover, accurately achieving the angles that have maximum angular separation requires a very high-resolution plate writer, as is used in commercial offset printing. Commercially available high-end digital printers cannot achieve this resolution. In this paper, we propose a systematic way to design color screen sets for periodic, clustered-dot screens that offer more explicit control of the moiré properties of the resulting screens when used in color printing. We develop a principled approach for the moiré-free screen design that is called lattice-based screen design. The basic concept behind our approach is the creation of the screen set on a 2D lattice in the frequency domain, and then picking each fundamental frequency vector of the individual colorant planes in the created spectral lattice according to the desired properties. The lattice-based screen design offers more flexibility in designing N -color screen sets with different halftone geometries, and all of them are guaranteed to be all-orders moiré-free. We demonstrate the efficacy of our proposed method by introducing several new screen designs, and a comparison with published screen designs.

    This report presents a series of low-temperature (4.5 K) scanning tunneling microscopy and spectroscopy experimental results on monolayer MoS2 deposited on highly oriented pyrolytic graphite using chemical vapor deposition. To reveal the detailed connection between atomic morphology and conductivity in twisted MoS2/graphite heterojunctions, we employ high-sensitivity tunneling spectroscopy measurements by choosing a reduced tip-sample distance. We discern previously unobserved conductance peaks within the band gap range of MoS2, and by comparing the tunneling spectra from MoS2 grains of varying rotation with respect to the substrate, show that these features have small but non-negligible dependence on the moiré superstructure. Furthermore, within a single moiré supercell, atomically resolved tunneling spectroscopy measurements show that the spectra between the moiré high and low areas are also distinct. These in-gap states are shown to have an energy shift attributed to their local lattice strain, matching corresponding behavior of the conduction band edge, and we therefore infer that these features are intrinsic to the density of states, rather than experimental artifacts, and attribute them to the twisted stacking and local strain energy of the MoS2/graphite heterointerface.

    Braided river patterns and sediment supply interactions are significant. Small-scale braided rivers were studied in a rectangular flume with an adjustable slope to investigate these relationships and to gain insight into the effect of grain sorting on bedform formation and migration. We used a 1.20-m-wide and 4.5-m-long flume and a mixture of fine and coarse sand ranging from 0.5 mm to 1.5 mm and from 1.5 to 3 mm (with median sizes 1 and 2 mm, respectively). The sediment feed rate and water discharge were maintained constant. The initial bed was flat with a 3% slope. The mean bed load discharge was calculated by weighing output sediments. The experiment produced bedforms and braided patterns. Equilibrium was reached with a constant number of moving bars. The Moiré method was used to study the bed topography and bedform migration precisely. This optical method considers deformations of grey fringes projected by a video projector on the bed topography. These deformations were recorded with a digital camera and analysed using the phase shifting method (with a special algorithm adapted to the experimental setup). Data produced by this algorithm were mapped with GIS software such as ArcGis. We chose the Moiré method among other methods (laser, photogrammetric, point gauge, etc.) because of its high spatial resolution and its simplicity. However, several technical aspects had to be resolved. Bed topography accuracy depends on the distance between the camera's focal plane and a reference plane parallel to the flume. As the flume and the rail supporting the camera were not parallel, this distance changed along the flume. Instead of moving constantly along a physical reference plane, two wedges were placed on the flume sides to create a virtual reference plane: a 2-cm-wide surface on the top of each wedge was extracted from photographs using image processing software, and these surfaces were used to extrapolate a single virtual reference plane for the whole flume.

    Aspheric optical components are an indispensable part of modern optics systems. With the development of aspheric optical elements fabrication technique, high-precision figure error test method of aspheric surfaces is a quite urgent issue now. We proposed a digital Moiré interferometer technique (DMIT) based on partial compensation principle for aspheric and freeform surface measurement. Different from traditional interferometer, DMIT consists of a real and a virtual interferometer. The virtual interferometer is simulated with Zemax software to perform phase-shifting and alignment. We can get the results by a series of calculation with the real interferogram and virtual interferograms generated by computer. DMIT requires a specific, reliable software system to ensure its normal work. Image acquisition and data processing are two important parts in this system. And it is also a challenge to realize the connection between the real and virtual interferometer. In this paper, we present a software system design for DMIT with friendly user interface and robust data processing features, enabling us to acquire the figure error of the measured asphere. We choose Visual C++ as the software development platform and control the ideal interferometer by using hybrid programming with Zemax. After image acquisition and data transmission, the system calls image processing algorithms written with Matlab to calculate the figure error of the measured asphere. We test the software system experimentally. In the experiment, we realize the measurement of an aspheric surface and prove the feasibility of the software system.

    The resolution of the electron beam moiré method depends on the line frequency of the grating. Recently, more and more effort has been devoted to increase the frequency, and a novel method for producing high-resolution electron beam gratings is presented in this work. Cross-gratings with a frequency up to 14,832 lines/mm (67 nm pitch) were successfully fabricated using a common scanning electron microscope without a dedicated pattern generation system. The quality of the grating was high enough to produce high-quality moiré fringe patterns. In this method, the ultra-fine cross-grating can be fabricated only through one-directional scanning on the resist, which can improve the grating quality and significantly reduces the fabrication time. The number of control parameters for grating fabrication could be reduced to two compared to the six parameters required by conventional methods, which facilitates the use of the electron beam moiré method. The frequency of the fabricated grating is linearly proportional to the exposure magnification. Thus, the frequency of the grating can be accurately predetermined, and the null field can be easily obtained in the electron beam moiré method. The quality of the fabricated gratings was illustrated by the obtained micrographs and moiré fringe patterns. The full-field local strain near an induced crack was studied to verify the application potential of this method.

    We have proposed a virtual quadratic Newton rings phase-shifting moiré-fringes measurement method in a nonnull interferometer to measure the large radius of curvature for a spherical surface. In a quadratic polar coordinate system, linear carrier testing Newton rings interferogram and virtual Newton rings interferogram form the moiré fringes. It is possible to retrieve the wavefront difference data between the testing and standard spherical surface from the moiré fringes after low-pass filtering. Based on the wavefront difference data, we deduced a precise formula to calculate the radius of curvature in the quadratic polar coordinate system. We calculated the retrace error in the nonnull interferometer using the multi-configuration model of the nonnull interferometric system in ZEMAX. Our experimental results indicate that the measurement accuracy is better than 0.18% for a spherical mirror with a radius of curvature of 41,400 mm.

It is an optical bio-stereometric method to give a three dimensio-ned image of the back. By its sensitivity, even minor asymetricity between the two sides of the back can be disclosed. Normally the moire shadow of both shoulder blades, hips and lumbars should be exactly symmetrical. 1055 children from 4 primary schools, aged between 6-14 were investigated. 598 were boys and 466 girls. Moire fringe asymmetry was observed in 65 of them (16.2%). X-ray films were taken in 55 of these 65 asymmetric children, and proved them to have a 5°-20° scoliosis. Moire photography as a non-traumatic technique is feasible in school-screening program for pupils with any observed asymmetry of the back. X-ray films should be taken in positive cases. When the Moire photography displays 2 Moire fringes of asymmetry while X-ray films shows a curve more than 10°, orthopedic treatment combined with exercises under medical supervision should be advised.%@@ 青少年脊柱侧弯症在我国发病率仍然很高(1),近十年来,国外采用波纹照像的方法,为早期诊断脊柱侧弯提供可靠依据.近年来,我院与北京工业学院共同研制出一套波纹照像仪,并普查了1,055名学生及应用于临床.发现对轻型脊柱侧弯儿童阳性分辨率高.

Au-delà du drame humain qui a fait plus d’une centaine de morts et plus d’un millier de blessés, cette contestation s’est formulée autour d’une organisation anachronique : les aarch. Système sociopolitique ancien dont les dernières traces d’existence remontent à la fin du XIXe siècle, il a mobilisé dans et par la tribu reconfigurée selon les besoins contemporains. Cette utilisation d’une organisation sociale maghrébine a permis de une inscription dans le temps par la mémoire mobilisée par la tribu.En effet, dans une perspective politique, les aarch, pour contester le présent, ont mis en exergue des patrimoines historiques et mémoriels effacés par l’État nation algérien. Mobilisant ainsi l’histoire de la guerre de décolonisation, fondatrice de l’État indépendant, les aarch se sont directement attaqués au vouloir vivre ensemble, redéfinissant les bases constitutives de la nation. Cette dynamique mémorielle et historique a aussi permis aux militants et partisans de revisiter un passé plus lointain : crises au sein du mouvement nationaliste, mouvements sociaux post Indépendance, etc. Ce remaniement des mémoires, dont la culture et la langue restent les socles, a permis d’envisager des territoires culturels, identitaires dépassant les frontières stato-nationales.Si ces données sont celles du politique, des militants, les bases sociales du mouvement, qui a mobilisé jusqu’à 1,5 million de personnes, ont réutilisé ces outils de la contestation pour les transformer en sources du malaise socioéconomique contemporain.The riots that have bloodstained Kabylie in the spring of 2001 have raised different problematics.

  12. The Development and Hover Test Application of a Projection Moire Interferometry Blade Displacement Measurement System

    2012-01-01

    Projection moir interferometry (PMI) was employed to measure blade deflections during a hover test of a generic model-scale rotor in the NASA Langley 14x22 subsonic wind tunnel s hover facility. PMI was one of several optical measurement techniques tasked to acquire deflection and flow visualization data for a rotor at several distinct heights above a ground plane. Two of the main objectives of this test were to demonstrate that multiple optical measurement techniques can be used simultaneously to acquire data and to identify and address deficiencies in the techniques. Several PMI-specific technical challenges needed to be addressed during the test and in post-processing of the data. These challenges included developing an efficient and accurate calibration method for an extremely large (65 inch) height range; automating the analysis of the large amount of data acquired during the test; and developing a method to determinate the absolute displacement of rotor blades without a required anchor point measurement. The results indicate that the use of a single-camera/single-projector approach for the large height range reduced the accuracy of the PMI system compared to PMI systems designed for smaller height ranges. The lack of the anchor point measurement (due to a technical issue with one of the other measurement techniques) limited the ability of the PMI system to correctly measure blade displacements to only one of the three rotor heights tested. The new calibration technique reduced the data required by 80 percent while new post-processing algorithms successfully automated the process of locating rotor blades in images, determining the blade quarter chord location, and calculating the blade root and blade tip heights above the ground plane.

    The structural and electronic properties of a Pb monolayer (ML) grown on Au(111) are investigated by scanning tunneling microscopy (STM) and angle resolved photoelectron spectroscopy (ARPES). We find an incommensurate Moiré structure with an approximate (5.77×5.77) R21.5∘ unit cell, and two rotational domains. We observe three Pb-derived bands of p orbital character. The symmetry properties and sharpness of their Fermi surfaces are remarkably different. They reflect the different degrees of hybridization of these bands with the Au(111) bulk continuum.

    Dentin is a biological composite that forms the major bulk of tooth structure. Understanding the biomechanical response of dentin structure to forces is essential to restore the loss of mechanical integrity associated with dentin loss during disease or treatment procedures. Moiré interferometry is an optical interferometry based method, which allows wholefield, real-time analysis of dental structures with high-sensitivity. The aim of this study was to investigate the deformation gradients in dentin during function and subsequent to surface conditioning with bioactive biopolymeric nanoparticle. Slab shaped dentin specimens were prepared and a customized loading jig was used to compressively load the specimens from 10 N to 50 N. Specific regions of interest was chosen on the dentin specimens for strain analysis. The digital moiré interferometry experiments showed a distinct deformation pattern in dentin in the direction perpendicular to the dentinal tubules, which increased with increase in dentin loss. The dentin conditioned with nanoparticles did not display marked increase in strain gradients with loads. The current photomechanical experiment highlighted the impact of nanoparticle treatment to improve the mechanical integrity of dentin.

    Full Text Available La complexité syntaxique d’une phrase en langage oral peut se caractériser par le nombre et la nature des opérations syntaxiques nécessaires à son élaboration, et notamment par la profondeur de son enchâssement. Cette complexité influence l’âge d’acquisition des différentes structures syntaxiques, les énoncés les plus complexes étant maîtrisés plus tardivement par l’enfant. Certains auteurs attribuent cette acquisition de la syntaxe complexe à des contraintes développementales externes au système linguistique lui-même et notamment à des limitations dans les capacités de mémoire de travail (Jakubowicz, 2007. Ainsi, le traitement d’une phrase complexe engendrerait un coût cognitif important et constituerait une surcharge pour des capacités de mémoire de travail davantage limitées chez le jeune enfant. La maturation normale de ce système mnémonique permettrait ensuite à l’enfant de comprendre et de produire des énoncés de plus en plus complexes.

Cette étude se penche sur la question essentielle du rapport qu’entretiennent l’Histoire, sa représentation au cinéma et le positionnement du spectateur au sein d’un dispositif qui fait appel à ses affects, à son « flot mémoriel », à ses souvenirs, dispositif qui tente de palier à « l’oubli » qui est l’une des caractéristiques de la mémoire.The relation between cinema and history, between the past as we know it and its representation on the screen is a fascinating subject. However, inducing this topic without a reference to the viewer cannot be as complete as it should be because it neglects the problematical theme of the spectator’s memory, his situation facing a specific event and in front of the image of this event. This essential issue about the connection between history, its representation in films and the condition of the viewer involved into a scheme in which his “ memory flow”, emotions, and souvenirs are concerned, a scheme trying to replace the elapsed memories, is the subject if this essay.

    Full Text Available Objetivou-se avaliar os efeitos da classe diamétrica e das umidades geral e do alburno sobre a retenção de CCA-C (arseniato de cobre cromatado tipo C na madeira de clone de Eucalyptus urophylla preservada em autoclave. Foram utilizados 36 moirões pertencentes às classes diamétricas de 7, 9, 11 e 13 cm, que foram separados e expostos a três tempos de secagem ao ar livre: 20, 40 e 70 dias. Determinaram-se os valores de umidade pré-tratamento, geral e apenas do alburno, por classe diamétrica e por tempo de secagem. Após a preservação em autoclave, foi feito o controle de qualidade do tratamento preservativo, por meio da análise de retenção do CCA-C. A retenção nos moirões da classe de 7 cm foi superior à das classes de 9, 11 e 13 cm, que não variaram estatisticamente entre si. O aumento do tempo de secagem de 20 para 40 dias proporcionou incremento significativo na retenção média de 5,70 para 6,67 kg I.A*m-3. As variações médias das umidades geral e do alburno se mostraram significativas com a variação da retenção, apresentando boa correlação entre os fatores. A correlação entre a umidade geral e a retenção de CCA-C (r = -0,86 foi mais forte que a correlação entre a umidade do alburno e a retenção (r = -0,70.

    The conception of a tridimensional digital model of solid figures and plant organs started from topographic survey of virtual surfaces [1], followed by topographic survey of solid figures [2], fruit surface survey [3] and finally the generation of a 3D digital model [4] as presented by [1]. In this research work, i.e. step number [4] tested objects included cylinders, cubes, spheres and fruits. A Ronchi grid named G1 was generated in a PC, from which other grids referred as G2, G3, and G4 were set out of phase by 1/4, 1/2 and 3/4 of period from G1. Grid G1 was then projected onto the samples surface. Projected grid was named Gd. The difference between Gd and G1 followed by filtration generated de moiré fringes M1 and so on, obtaining the fringes M2, M3 and M4 from Gd. Fringes are out of phase one from each other by 1/4 of period, which were processed by the Rising Sun Moiré software to produce packed phase and further on, the unpacked fringes. Tested object was placed on a goniometer and rotate to generate four surfaces topography. These four surveyed surfaces were assembled by means of a SCILAB software, obtaining a three column matrix, corresponding to the object coordinates xi, also having elevation values and coordinates corrected as well. The work includes conclusions on the reliability of the proposed method as well as the setup simplicity and of low cost.

    Full Text Available Depuis la fin du XXe siècle, les recherches menées sur l’autobiographie et l’autofiction soulignent les effets du discours postmoderne sur la notion d’identité. Chez Marguerite Andersen, romancière franco-ontarienne d’origine allemande, qui se représente dans quatre livres – le roman « semi-autobiographique » De mémoire de femme, le récit autobiographique Parallèles, la prose poétique Bleu sur blanc et le roman autobiographique Le figuier sur le toit – de même que dans certaines nouvelles des Crus de l’Esplanade, cette construction s’avère être un processus dynamique et créatif de mise au monde de soi. Nous nous pencherons sur De mémoire de femme pour explorer comment l’éloignement de différentes figures d’altérité à un moment particulier dans la vie de la protagoniste incite chez elle le désir de se raconter et d’ajuster en quelque sorte son tir en ce qui concerne son identité. À l’aide des théories énoncées par Éric Landowski, Charles Taylor et Julia Kristeva, nous verrons comment l’exercice narratif est mis en branle par le déséquilibre provoqué par l’absence de l’autre que l’écrivaine cherche à combler dans le but de s’épanouir.

    Full Text Available L’espace libanais est caractérisé par l’absence d’une mémoire collective nationale au profit de plusieurs mémoires sociales portées par les différents groupes identitaires confessionnels et élaborées en fonction des relations conflictuelles ou conviviales qu’ils entretenaient entre eux. Ces mémoires rivalisent entre elles et avec une autre mémoire, construite à partir du début du xxe siècle par des tenants de la coexistence et hissée au rang d’histoire officielle, dans une vaine tentative de promouvoir une vision fédératrice de l’histoire du pays. Les mémoires élaborées autour des affrontements druzo-chrétiens du xixe siècle sont particulièrement illustratives de cette disjonction. Le fait que ce moment fondateur de la question du Liban, soit le produit d’un conflit sanglant est presque passé sous silence dans l’histoire officielle. Un sondage des mémoires communautaires chrétienne et druze pour la période 1820-61 permet de saisir comment ces mémoires vives, elles-mêmes en conflit, ont sapé l’histoire officielle, rendant compte d’un échec des historiens de la coexistence à imposer un récit censuré et pudique comme base d’une mémoire historique commune.

    2006-01-01

    Residual stresses in ion-implanted NiTi alloy are measured by a combined method of Moiré interferometry and hole-drilling. Oxygen ions are implanted into the NiTi alloy under a voltage of 30 kV by a dose of 1.0×1017 ions/cm2 for one hour. Subsequently, in order to avoid dimensional error, a hole is drilled exactly in the center of the sample. The distribution of residual stresses around the hole is measured. It is indicated that the method which combines the Moiré interferometry with hole-drilling is able to be used to measure residual stresses produced by ion implantation.

    Full Text Available Dans l’histoire écossaise moderne, peu d’événements ont autant de résonance et de charge émotionnelle que les évictions des paysans du Nord du pays et les conflits qu’elles engendrèrent entre le milieu du 18ème siècle et 1886, année où une loi garantissant l’accès à la terre à une partie de la paysannerie concernée limita considérablement le droit des propriétaires et mit un terme aux expulsions massives. Connus sous le nom de Highland Clearances, ces événementsn’ont rien perdu de leur pouvoir mobilisateur. Les adjectifs « contesté », ou « controversé » leur sont couramment appliqués ainsi qu’à leurs représentations, qu’elles soient littéraires ou historiques. Cet article s’appuie sur la notion de « mémoire culturelle », développée par Jan Assman, pour analyser le sens, les valeurs et la vision du monde cristallisés dans la mémoire collective des Clearances. S’attachant à l’historiographie des Clearances, à la production littéraire sur la période et à son appropriation politique, il met en lumière la cohérence et la stabilité de la mémoire culturelle des Clearances. Ces dernières sont, par conséquent, devenues un symbole puissant dans le discours politique écossais ; Nationalistes et Travaillistes écossais s’en sont emparés pour alimenter des argumentaires en faveur de la réforme de la propriété foncière, de l’accès à la terre, en résumé la démocratisation du système foncier.In Modern Scottish history, few events have had as much resonance and emotional charge as the Highland Clearances, i.e. the evictions of tenants and the social conflicts in northern Scotland and the Hebrides from the middle of the 18th century until 1886, when legislation put an end to large-scale removals by conferring security of tenure on crofters and considerably restricting landowning power. The Highland Clearances still retain much of their mobilizing power. The adjectives

    Full Text Available De nos jours en Russie, parmi les diverses interprétations du passé soviétique, une portion de la population tend à réactualiser la mise en valeur des réalisations technologiques, scientifiques et politiques du régime stalinien. Dans cette optique, l’histoire des répressions est préférablement mise de côté ou son importance minimisée. L’oubli est une menace constante pour les survivants des répressions mais plusieurs espèrent, malgré la diminution de l’intérêt manifesté par le public, obtenir une place dans le récit historique collectif. Certaines victimes font face à l’oubli et cherchent à donner un sens à leur expérience tragique par le biais de la narration. Lorsque ces dernières disparaissent, ce sont parfois leurs descendants qui poursuivent le travail de mémoire. La fille d’un intellectuel kazakh réprimé dans les années 1930, Larissa Kouderina, tente de rétablir la vérité sur le passé de sa famille. Elle souhaite également, dans une perspective plus vaste, faire reconnaître l’histoire de tout un groupe d’intellectuels kazakhs du début du XXe siècle. Pour réaliser ses objectifs, elle a d’abord publié les mémoires de sa mère ainsi qu’un essai qu’elle a rédigé sur l’histoire de son père et de la « première intelligentsia » à laquelle il appartenait. Depuis, elle prépare et espère un jour ouvrir un petit musée dédié à cette dernière. Ses publications et son musée constituent, dans ma perspective de recherche, les composantes d’un projet de commémoration. Ce projet est en quelque sorte une mission qu’elle s’est donnée, qui donne sens à sa vie et qui contribue à la construction de son identité. Dans cet article, j’observe comment les discours de l’histoire et de la mémoire sont conjugués à l’intérieur de son projet et comment elle s’est constituée en porte-parole non seulement de sa famille mais aussi d’une génération intellectuelle.

  3. Miss Julie: A Psychoanalytic Study

    2015-10-01

    Full Text Available Sigmund Freud theorized that ‘the hero of the tragedy must suffer…to bear the burden of tragic guilt…(that lay in rebellion against some divine or human authority.’ August Strindberg, the Swedish poet, playwright, author and visual artist, like Shakespeare before him, portrayed insanity as the ultimate of tragic conflict. In this paper I seek to explore and reiterate the dynamics of human relationships that are as relevant today as they were in Strindberg’s time. I propose to examine Strindberg’s Miss Julie, a play set in nineteenth century Sweden, through a psychoanalytic lens. The play deals with bold themes of class and sexual identity politics. Notwithstanding the progress made in breaking down gender barriers, the inequalities inherent in a patriarchal system persist in modern society. Miss Julie highlights these imbalances. My analysis of the play deals with issues of culture and psyche, and draws on Freud, Melanie Klein, Lacan, Luce Irigaray and other contemporary feminists. Miss Julie is a discourse on hysteria, which is still pivotal to psychoanalysis. Prominent philosophers like Hegel and the psychoanalyst Jacques Lacan have written about the dialectic of the master and the slave – a relationship that is characterized by dependence, demand and cruelty. The history of human civilization shows beyond any doubt that there is an intimate connection between cruelty and the sexual instinct. An analysis of the text is carried out using the sado-masochistic dynamic as well the slave-master discourse. I argue that Miss Julie subverts the slave-master relationship. The struggle for dominance and power is closely linked with the theme of sexuality in the unconscious. To quote the English actor and director Alan Rickman, ‘Watching or working on the plays of Strindberg is like seeing the skin, flesh and bones of life separated from each other. Challenging and timeless.’

    Full Text Available We propose a method to characterize the mechanical properties of cells using a robot-integrated microfluidic chip (robochip and microscopy. The microfluidic chip is designed to apply the specified deformations to a single detached cell using an on-chip actuator probe. The reaction force is simultaneously measured using an on-chip force sensor composed of a hollow folded beam and probe structure. In order to measure the cellular characteristics in further detail, a sub-pixel level of resolution of probe position is required. Therefore, we utilize the phase detection of moiré fringe. Using this method, the experimental resolution of the probe position reaches 42 nm. This is approximately ten times smaller than the optical wavelength, which is the limit of sharp imaging with a microscope. Calibration of the force sensor is also important in accurately measuring cellular reaction forces. We calibrated the spring constant from the frequency response, by the proposed sensing method of the probe position. As a representative of mechanical characteristics, we measured the elastic modulus of Madin-Darby Cannie Kidney (MDCK cells. In spite of the rigid spring constant, the resolution and sensitivity were twice that achieved in our previous study. Unique cellular characteristics can be elucidated by the improvements in sensing resolution and accuracy.

  6. Coherently stacked MoS2/WSe2 heterostructures: Moiré pattern and its effect on interlayer couplings

    Vertically stacked heterojunctions (HJs) of transition metal dichalcogenides (TMDs) have been proposed as fundamental building blocks for several novel electronic and photonic devices. Although such HJs can be easily achieved by sequential transferring of different TMDs, this approach is not scalable, and the orientation relationship between the layers is difficult to control. A much more desirable approach is to directly grow one kind of TMD on top of the other. In addition to being a scalable platform, the epitaxial approach also results in a well-defined orientation relationship. A very important question to ask is ``What is the role of the interlayer coupling on the electronic structures of such a bilayer stack?'' By using scanning tunneling microscopy/spectroscopy (STM/S) and first-principles calculations, we investigate the MoS2/WSe2 vertical heterojunctions formed by direct epitaxial growth. The different lateral lattice constants between MoS2 and WSe2 lead to the formation of a well-ordered Moire pattern with a superlattice constant of ~8.5 nm. This superlattice reflects the variation of the lateral alignment between the MoS2 and WSe2 lattices. STS shows very large variations of interlayer coupling, as a function of the lateral alignment. More interestingly, depending on the location in the BZ, the interlayer coupling has very different consequences on the electronic structures.

    We have recently developed precise x-ray grids having strip densities in the range of 100 - 250 lines/inch by adopting the precision sawing process and carbon interspace material for the demands of specific x-ray imaging techniques. However, quality assurance in the grid manufacturing has not yet satisfactorily conducted because grid strips of a high strip density are often invisible through an x-ray nondestructive testing with a flat-panel detector of an ordinary pixel resolution (>100 μm). In this work, we propose a useful method to evaluate actual grid strip densities over the Nyquist sampling rate based on the moiré artifact analysis. We performed a systematic simulation and experiment with several sample grids and a detector having a 143- μm pixel resolution to verify the proposed quality assurance method. According to our results, the relative differences between the nominal and the evaluated grid strip densities were within 0.2% and 1.8% in the simulation and experiment, respectively, which demonstrates that the proposed method is viable with an ordinary detector having a moderate pixel resolution for quality assurance in grid manufacturing.

    Full Text Available Political education after july 22. This article makes the case fordeliberation as a major end-in-view for a political education in the general sense. The immediate backdrop is the neofascist ideology of Anders Behring Breivik and his ilk, an ideology that may partly explain the motive behind the devastation of government buildings in Oslo and the following mass shooting at Utøya on July 22. My intention here will, however, be limited to the question: what is basic to the idea of deliberation? My answer is twofold: deliberation is a reasonable method for arriving at a possible and temporary agreement on questions of truth and morality; and it is based on some – usually tacit – mutual presuppositions. These two aspects together make deliberation educative and part of an education for deliberative democracy. Without deliberation as a method we are unable to get at what John Dewey used to call “warranted assertibility”. Without deliberation as embedded in joint assumptions we would be unable to distinguish between method as wayward gibberish and as reasonable conversation. On pain of being presumptuous I invite the reader to this short educative stroll!

    2015-05-01

    For the first time an x-ray Talbot-Lau moire deflectometer is being developed that will use a flash tube source and fast detector for dynamic density gradient measurements. In Talbot-Lau moire deflectometry, an x-ray grating makes an image of itself on a second grating (the Talbot effect) to produce a moire pattern on a detector. The test object is placed between these gratings, with variations in index of refraction changing the pattern. A third grating in front of an incoherent x-ray source produces an array of coherent sources. With a 150 kV x-ray flash tube as the source, the gratings are placed in a glancing angle setup for performance at ~60 keV. The detector is a gated CCD with a fast scintillator for x-ray conversion. This diagnostic, designed for the Dual-Axis Radiographic Hydrodynamic Test facility (DARHT) at Los Alamos National Laboratory, measures the density profile of dense plasma plumes ejected from beam-target interactions. DARHT has two high-current, pulsed, inductive linear electron accelerators with bremsstrahlung targets at the end of each beam line to create 2-D radiographic images of hydrodynamic tests. One multi-pulse accelerator has up to four beam pulses striking the same target within 2 μs. Computer simulations that model target evolution and ejected material between pulses are used to design these targets for optimal radiographic performance; the x-ray deflectometer will directly measure density gradients in the ejected plumes and provide the first experimental constraints to these models. During the first year, currently underway, the diagnostic systems are being designed. In year two, the flash tube and fast detector will be deployed at DARHT for radiographic imaging while the deflectometer is built and tested on the bench with a continuous source. Finally, in year three, the fast deflectometer will be installed on DARHT and density measurements will be performed.

    Full Text Available Selon Gaston Bachelard, la maison est tantôt le coffre de nos souvenirs, tantôt un état d’âme. Cela veut dire que, même avant de devenir figure onirique ou lieu imaginé de notre passé-futur, la maison abrite et rend possible le processus de la mémoire. Et, parce qu’elle révèle une intimité, soit aux éléments extérieurs, soit aux détails intérieurs, elle fait toujours figure de présent. Renfermant un univers personnel et familier, pourtant, en même temps, exhibant des mécanismes d’ouverture, la maison trace une ligne entre le soi et les autres, entre le groupe et le pluriel. Avec ses murs, ses fenêtres et ses portes, la maison permet le dialogue. La porte, par exemple, s’ouvre à l’ami bienvenu et se resserre face à l’ennemi, ce qui fait de la maison la place de l’hospitalité aussi bien que de l’hostilité. Enfin, elle comporte le seuil, marque distinctive de l’ensemble sémantique de la maison, parce qu’il est le corridor que l’on traverse aussi bien pour entrer que pour sortir. Toujours début et fin, le seuil surpasse la face de Janus en obligeant la confrontation des deux faces, comme si l’identité ne pouvait rien voir sans l’altérité. C’est notre objectif d’éclairer le rôle que la maison accomplit comme grande mémoire de nos souvenirs, devant laquelle le seuil signale une ambiguïté pas toujours pacifique, soit du point de vue du sujet qui habite, soit du point de vue de celui qui frappe à la porte: l’hôte, l’intrus, l’étranger.  According to Gaston Bachelard, the house is sometimes our box of souvenirs, sometimes a state of mind. It means that even before becoming a dream figure or an imagined place of our past-future, the house all at once holds and makes possible the process of memory. And because the house reveals intimacy, either to exterior elements or to interior details, it always is an actor of the present. While enclosing a personal and familiar universe, it

    A pressure ulcer is one of the most important concerns for wheelchair bound patients with spinal cord injuries. A pressure ulcer is a localized injury near the buttocks that bear ischial tuberosity oppression over a long period of time. Due to elevated compression to blood vessels, the surrounding tissues suffer from a lack of oxygen and nutrition. The ulcers eventually lead to skin damage followed by tissue necrosis. The current medical strategy is to minimize the occurrence of pressure ulcers by regularly helping patients change their posture. However, these methods do not always work effectively or well. As a solution to fundamentally prevent pressure ulcers, a smart air cushion system was developed to detect and control pressure actively. The air cushion works by automatically adjusting a patient's sitting posture to effectively relieve the buttock pressure. To analyze the correlation between the dynamic pressure profiles of an air cell with a patient's weight, a projection Moiré system was adopted to measure the deformation of an air cell and its associated stress distribution. Combining a full-field deformation imaging with air pressure measured within an air cell, the patient's weight and the stress distribution can be simultaneously obtained. By integrating a full-field optical metrology with a time varying pressure sensor output coupled with different active air control algorithms for various designs, we can tailor the ratio of the air cells. Our preliminary data suggests that this newly developed smart air cushion has the potential to selectively reduce localized compression on the tissues at the buttocks. Furthermore, it can take a patient's weight which is an additional benefit so that medical personnel can reference it to prescribe the correct drug dosages.

    The mutual evolving processes of signals' waveforms and their spectra were numerically analyzed in time and frequency domains. The purpose was to research the essential relation between the signals' waveforms and their spectra. Then, the mutual transform principle was applied to analyze moiré pattern spectra, acquiring phase distribution information of the pattern. The rectangular window function was used to simulate the mutual transform between the impulse signal and direct-current waveform. Many rectangular window signals with deferent widths were obtained by changing the window width The unit impulse signal was obtained by changing the width down to zero, and the direct-current waveform obtained by changing the width up to +infinity. For smart, quick, and easy implementation of discrete Fourier transforms to rectangular pulses and obtain signals' spectra, a simple FFT system was worked out. With its calculating, the mutual evolving processes of signals' waveforms and their spectra were tracked deeply. All signals here were transformed with it. As the result, first, the spectra of rectangular window signals were in the form of sampling function [Sa(x) = sin(x)/x]. Second, with the change in the window's width, the waveform of Sa(x) changed. Third, when the width decreased, the waveform of Sa(x) extended, and vibrated more slowly. It changed into direct-current waveform when the width decreased to zero. Last, when the width increased, the waveform of Sa(x) shranked, and vibrated faster. It changed into impulse waveform when the width increased to +infinity. Signals' waveforms were in mutual transforms between the time and frequency domain. The transforming essence was considered as that the frequency component principle in Fourier series theory is reflected in the frequency domain. According to the principle of mutual transforms between signals' waveforms and their spectra, the first order spectrum of the moiré pattern was extracted out and normalized to a

  20. Circular gratings' moiré effect for projection measurement in volume optical computerized tomography with two-step phase-shifting method

    2012-11-01

    Volume optical computerized tomography (VOCT), which can realize real 3D measurement rather than traditional 2D OCT, has great superiority in quantitatively measuring the thermo physical parameters of transient flow field. Among the refractive index reconstruction techniques, filtered back-projection (FBP) method performs better than algebraic reconstruction techniques (ARTs) with higher accuracy and computationally efficient. In order to apply FBP to VOCT, the radial second-order derivative of projection wave front passes through the tested phase object should be obtained firstly. In this paper, a projection device with two circular gratings is established. In particular, owing to an inherent phase shift exists between moiré fringes of +1 and -1 diffraction orders, a two-step phase-shifting algorithm is utilized to extract the wave front's radial first-order derivative which is contained in the moiré fringes. The reliability of the two-step phase-shifting algorithm is proved by a computer simulation. Finally, the radial first-order derivative of wave front passing through a propane flame is measured and retrieved by these methods.

    As the continuous reduction of cost and rapid development of technology, three dimensional printing technologies have been used in a wide array of applications, and its products has gradually stepped into public life. Currently, one of the biggest barriers in the development of the 3D printing technology is the simple and monotonous exterior appearance of the products, which rarely have complex and rich pattern or colors. Based on the Moire phenomenon in the 3D printing process, this paper analyzes the formation of this phenomenon, which is subsequently applied in the construction of dynamic pattern in the appearance of fabricated parts. Then, the dynamic pattern is extended to the dynamic geometry for the appearance of parts by integrating the expected geometry into the tool-path for each layer in the filling process. The dynamic geometry can be relatively complex depending on the tool path design. The results of this research provide an effective method for improving the exterior appearance of fabricated parts, and also increase the potential application of 3D printing technologies.%随着成本的不断降低与技术的快速发展,三维打印技术(three dimensional printing,3DP)在越来越多的领域得到应用,制造的产品也逐渐步入大众的生活。目前阻碍3DP产品进一步推广的一个很大瓶颈在于单调呆板的产品外观,很难制造出具有复杂丰富表面的制件。本文对三维打印中莫尔现象的形成机理进行研究并将该现象用于构建动态条纹来使3DP的制件拥有复杂变化的表面外观。基于动态条纹的形成原理,将期望的几何图案信息整合到层片的填充路径中最后可得到复杂的动态图案。该研究成果为提高制件的外观质量提供了有效的解决方法,可进一步扩展三维打印技术的应用领域。

Autrement dit, il s’agit pour nous de chercher à identifier quelques unes des marques linguistiques d’une auctorialité en devenir, que nous appelons, donc, au(ctorisation. Certaines formes linguistiques notables, comme les hésitations pronominales entre je et nous ou entre nous et on, attestent des tensions supportées par le sujet écrivant apprenti chercheur, notamment entre intégration dans une communauté discursive et émergence du sujet auteur, entre retrait objectif et implication personnelle, mais ne suffisent pas à garantir l’aboutissement du processus de négociation dialogique visant à élaborer sa propre voix à partir de celles d’autrui. D’autres en revanche, relatives à l’intégration des sources ou au statut épistémique des assertions par exemple, sont susceptibles de traduire des différences dans l’attitude – plus ou moins créative – du scripteur. Le mémoire de master pourrait ainsi porter les traces d’une forme d’au(ctorisation et révéler quelque chose de la manière dont on devient – ou non – auteur.

    Full Text Available Cet article a pour objectif premier de tracer les contours du processus d’oubli collectif qui ont longtemps entouré la répression policière de la manifestation du 17 octobre 1961, à Paris, durant la guerre d’Algérie. Pour ce faire, l’auteur prend le parti de traiter l’oubli pour ce qu’il est : une forme de mémoire. Abordant de manière contextuelle les différents éléments ayant participé à cette absence d’histoire, il expose les censures, amnisties, amnésies, silences et discours officiels ou médiatiques, comme autant de bornes aux cadres sociaux de la mémoire de cet événement et de la violence qu’il a engendrée. Proposant une analyse anthropologique de la multifactorialité de cet oubli, l’auteur met à jour une forme masquée de coopération collective sans laquelle aucun scotome n’aurait pu être durablement maintenu, et dégage un champ d’unification entre mémoire et histoire. Un tel oubli collectif se révèle alors être à la fois incroyablement composite, car mettant en jeu de façon croisée le politique et le cognitif, le collectif et l’individuel, mais également être le fait de tous, là où l’attention ne se porte généralement que sur les institutions nationales. Enfin, cet article s’achève sur le potentiel mémoriel de l’oubli comme conclusion inachevée qui sans cesse se joue au présent.This article explores the processes of collective forgetting around the police repression of the October 17th 1961 demonstration in Paris during the Algerian war. In this article, the author treats oblivion as a form of memory. By addressing contextually the different elements involved in this lack of history, it exposes the censorship, amnesty, amnesia, silence and official or media discourses as limits to the social frameworks of the collective memory of this event and the violence it generated. Offering an anthropological analysis of the plurality of factors of this

    Full Text Available La responsabilité morale et politique à l’égard du passé est toujours sous-jacente dans la culture politique allemande. Toute tentative destinée à penser l’identité nationale, à mettre à jour ses principales caractéristiques, se trouve confrontée à la prégnance d’une mémoire collective particulièrement lourde de sens et de conséquences. De récentes polémiques sur l’attitude à adopter face à l’histoire et à l’idée nationale montrent combien cet héritage est structurant dans la réflexion sur la problématique identitaire. Si l’histoire, la mémoire et l’identité semblent indissociables dans ce contexte spécifique, des aspirations à une certaine « normalité » se manifestent quant à la manière de vivre ce passé et de s’exprimer au présent. La chute du Mur de Berlin et la réunification ont replacé le thème de l’identité nationale au centre des débats, réactivant ainsi une forme de dilemme entre un sentiment de culpabilité devant l’histoire et le désir d’un rapport « normalisé » à la nation allemande. Les transformations dont l’Allemagne est le théâtre depuis la dernière décennie rendent toutefois nécessaire le maintien d’une vigilante attention. Une situation d’insécurité économique et sociale, associée au temps qui risque d’atténuer la vivacité de souvenirs pourtant lourds, rappellent que la mémoire conditionne aussi la manière dont une nation réunifiée se projette dans l’avenir et y vit son identité.The moral and political responsibility regarding the past always underlies German political culture.

    "Bravo! A huge success! A big thanks to everyone involved for their valuable participation this summer," says Ms. Troillet, the nurse responsible for the Transfusion Centre (CTS) at HUG.   During the 24 July blood donation, blood was collected from 109 of the 150 people who attended (including 53 new donors). This excellent result is particularly noteworthy, since blood supplies are at their lowest levels in hospitals during the summer season. The CERN Medical Service joins CTS in thanking all donors for their generous gesture and Ms. Vuattaz, manager of the restaurant NOVAE No. 2 and her team, for their collaboration.

    This progress report discusses activities at Hanford Engineer Works for the month of July, 1944. The organization size increased rapidly in July, jumping from 1384 to 1886, an increase of 502 employees. Shortages existed on special lines such as electricians, instrument mechanics, and power operators. The opportunities to interview and employ Construction personnel improved as the Construction, organization moved past its peak employment figure. 269 houses were completed in Richland and 370 occupancies were reported, reducing the backlog of empty houses due to slow furniture movements. A total of 1530 houses or 35.6% of the village is now occupied. The overall canning yield increased from 63% to 75% while production leveled off at approximately two-thirds of design capacity. The metal machining operation and the test pile operated on a one shift-six day per week basis. The portion of the 100-B Area from the pump house through the filter plant and including the Power House was taken over by Operations on July 25. The Power House in the 200-W Area was started and flushing of process lines with water and steam got under way in the canyon. A new department was formed to control the Protection activities of the plant.

    By using direct growth, we create a rotationally aligned MoS2/WSe2 hetero-bilayer as a designer van der Waals heterostructure. With rotational alignment, the lattice mismatch leads to a periodic variation of atomic registry between individual van der Waals layers, exhibiting a Moiré pattern with a well-defined periodicity. By combining scanning tunneling microscopy/spectroscopy, transmission electron microscopy, and first-principles calculations, we investigate interlayer coupling as a function of atomic registry. We quantitatively determine the influence of interlayer coupling on the electronic structure of the hetero-bilayer at different critical points. We show that the direct gap semiconductor concept is retained in the bilayer although the valence and conduction band edges are located at different layers. We further show that the local bandgap is periodically modulated in the X-Y direction with an amplitude of ~0.15 eV, leading to the formation of a two-dimensional electronic superlattice.

    BACKGROUND: Moiré interferometry method which belongs to the range of experiment mechanics is a modern photo-mechanics test technique. On the other hand, metal-porcelain restorations characterized as beautiful, compatible and stable properties are widely used in oral medicine domain. Moiré interferometry technique is applied in the oral restoration and some mechanics data can be obtained. It can be realized in discipline complementation and interaction between mechanics and bio-medicine engineering. OBJECTIVE: To introduce the moiré interferometry technique in details, and to study the displacement of metal-porcelain restorations under different loads by using the moiré interferometry technique as it is found that porcelains often flake off from the base of restorations in oral clinic. METHODS: The horizontal and vertical displacement of metal-porcelain restorations were measured by using the moiré interferometry method which is sensitive and easy to operate, and suitable for in-plane displacement measurement. The displacement was shown in the form of interferometry patterns. RESULTS and CONCLUSION: The interferometry patterns which represented the in-plane displacement of specimens were obtained and the displacement was linearly related with the loading changes. Moiré interferometry method can be used in measuring the displacement of restorations. Operation is simple and results are shown by interferometry patterns.%背景:云纹干涉法是现代光力学测试技术,是实验力学范畴.另外,金瓷修复体以其较好的生物相容性,色泽美观,坚固而广泛应用于临床,将云纹干涉技术应用口腔领域得到医学工程中所需位移量,体现学科交叉,较好的实现学科互补.目的:详细介绍了云纹干涉法原理以及试件栅的复制,针对临床经常发现口腔中瓷剥落等破坏行为,应用云纹干涉法来研究金瓷复合材料受力后的位移量.方法:采用云纹干涉技术测试金瓷试件在不同

  9. Investigation of Moiré pattern-based phase retrieval approach for differential phase-contrast cone beam CT imaging using a hospital-grade tube

    The phase stepping algorithm is commonly used for phase retrieval in grating-based differential phase-contrast (DPC) imaging, which requires multiple intensity images to compute one DPC image. It is not efficient for data acquisition, especially in the case of dynamic imaging using either DPC imaging or DPC-based come beam CT (DPC-CBCT) imaging. A Fourier transform-based approach has been developed for fringe pattern analysis in optics, and it was recently implemented into a synchrotron-based DPC tomography system. In this research, this approach is further developed for a bench-top DPC-CBCT imaging system with a hospital-grade x-ray tube. The key idea is to separate carrier fringes and object information in Fourier domain of the interferogram and to reconstruct the differentiated phase information using the object information. Only one interferogram is required for phase retrieval at a cost of spatial resolution. The fringes of moiré patterns are used as the carrier fringes, and a phantom is scanned to evaluate the approach. Various interferograms with different carrier fringe frequencies are investigated and the reconstruction image quality is evaluated in terms of contrast, noise and sharpness. The results indicated that the DPC images can be effectively retrieved using the Fourier transform-based approach and the reconstructed phase coefficient showed better contrast compared to that of attenuation-based contrast. The spatial resolution is acceptable in the phantom studies although it is not as good as the results of phase-stepping approach. The Fourier transform-based phase retrieval approach is able to greatly simplify data acquisition, to improve the temporal resolution and to make it possible for dynamic DPC-CBCT imaging. It is promising for perfusion imaging where spatial resolution is not a concern.

    Full Text Available Nombreux sont les anciens combattants qui ont participé aux mutineries de 1917 ou vécu ces événements avec une grande proximité. Pour autant, la transmission de la mémoire s’avère d’une grande complexité tant il est difficile d’assumer pleinement un mouvement collectif de désobéissance en pleine guerre, de lui affecter un sens stabilisé ou consensuel. Les AC témoignent des mutineries parce qu’ elles font partie de leur expérience de guerre et qu’ ils refusent en général toutes les formes de « bobards » qui enjolivent par trop ce qu’ils ont vécu. En même temps, leurs récits des révoltes de 1917 se font le plus souvent avec une mise à distance ici étudiée. On peut donc conclure à une forme de dualité mémorielle des mutineries.Many are the veterans who took part in the 1917 mutinies or who experienced them at close range. Yet, transmitting that memory proves extremely complex, so difficult it is to fully accept a mass movement of disobedience in wartime and award it a stable or consensual significance. The veterans bear witness to the 1917 mutinies as these were part of their war experience and because they generally reject any sort of «nonsense» that makes the past prettier than it actually was. At the same time, when they tell of these rebellions they usually mark their distance from their narrative - which is what is under study here. One might therefore conclude that these mutinies have become a sort of double memory.

On s’interroge sur la manière dont l’étudiant s’approprie ce nouveau rôle qui lui est « offert » à l’entrée en Master. Des entretiens semi-directifs ont été menés auprès de vingt binômes « directeur de mémoire-étudiant » appartenant à la discipline des Sciences de l'éducation, dans cinq universités différentes. Les résultats montrent qu’il y a un gap entre le projet de recherche initialement envisagé par l’étudiant « masterant » et le projet de recherche tel qu’il est attendu à ce niveau universitaire. Ce gap est à l’origine de tensions au sein du binôme si l’étudiant n’accepte pas de « faire le deuil » de son projet de recherche « idéal ».This article addresses one of the characteristics of the French Master’s degree in educational sciences, which makes it different from the Bachelor’s degree. Self-directed learning progressively increases in the way the student works, starting with his/her own choice of a research topic. I studied the way the student fits this new role. Semi-directed interviews were carried out with eighteen “supervisor-student” pairs in the discipline of educational sciences, in five different universities. The results show that there is a difference between the initial research that the student would like to lead and the research which is expected at Master’s degree. This gap leads to tension within the pedagogical relationship if the student does not accept to let go of his original ”ideal” research.

    2004-01-01

    The temperature change trends in January and July are analyzed and the results show that the trends descend in July but ascend in January except in South China and Southwest China. The relation between the temperature in January and July are discussed by using the wavelet. The results show that the trend phase in July and January are nearly in-phase in Southwest and South China, but are out-of-phase in other regions. Reconstruction of original temperature series in each of the regions indicates that their change trends are consistent with the original temperature series.

  1. VAMA VECHE WATERSPOUTS OF 16 JULY, 2013

    Full Text Available Vama Veche waterspouts of 16 july, 2013. As it is known, waterspouts generally occur in unstable thermodynamic stratification, light wind in the low troposphere and high Convective Available Potential Energy (CAPE in the low layers. High values of CAPE are not necessary if there is heavy windshear in the first 3 km from ground level. Waterspouts can be produced by storm clouds with both supercell and non-supercell structure. The existence of the analyzed waterspout event was checked based on the general conditions for waterspouts and tornadoes occurrence, as proposed by Houze and Dotzek. The possibility that waterspouts occur was also verified using the Szilaghyi nomogram. In this context event, the synoptic, mesoscale environment and radar data highlighted the light wind in the lower troposphere, the occurrence of a low-level “hook” echo and of rotating structures in the radar reflectivity field, the presence of the radar signature of a mesocyclone and the existence of instability, sufficient moisture and wind shears in the lower boundary layer. Moreover, with the help of in-situ pictures, it was proved that the Vama Veche storm cloud did not preserve its mesocyclone stage and produced a series of waterspouts.

  2. LHCC COMPREHENSIVE REVIEW OF CMS (JULY 07)

    CERN Multimedia

    Extract from the Draft Report 1. EXECUTIVE SUMMARY The CMS Collaboration has made significant progress towards producing a detector ready for LHC operation in 2008. The past year saw all sub-detector groups success fully produce high-quality components and modules, and integrate them into the final objects to be installed into the CMS magnet. Installation and commissioning of final components in the CMS UXC55 cavern are well-under-way. In particular, the heavy lowering of detector elements into the CMS experiment cavern is a major success. The new CMS master schedule V36 incorporates the revised LHC machine schedule and includes an optimized detector sequencing. In spite of various delays, it remains possible that CMS will have an initial detector ready to exploit the initial LHC run in spring 2008. Installation of the Electromagnetic Calorimeter End-Cap (EE) and Pre-shower (ES) detectors is scheduled to be completed no sooner than July 2008 and CMS now plans to install the complete Pixel Detector for ...

  6. La thèse du « génocide indien » : guerre de position entre science et mémoire

    Directory of Open Access Journals (Sweden)

    Frédéric Dorel

    2006-09-01

    Full Text Available Nombreuses sont les sources qui usent de l’expression « génocide indien » pour qualifier la destruction des populations indigènes du continent américain depuis l’arrivée des Européens. Or il s’avère que les massacres des populations amérindiennes ne sont pas à ce jour officiellement recensés parmi les génocides identifiés par l’Organisation des Nations Unies. Beaucoup s’indignent vivement devant cette injustice, d’autres justifient cette situation par une analyse moins strictement émotionnelle des étapes de la disparition des populations. Nous assistons ici à l’opposition entre deux visions de l’histoire, deux utilisations du passé. La première trouve une justification morale dans le devoir de mémoire et dans la loi (la Convention des Nations Unies pour la prévention et la répression des crimes de génocide de 1948 ; la seconde trouve une argumentation scientifique dans une vision ethnologique selon laquelle s’il y a eu incontestablement crime contre l’humanité à l’égard des populations indigènes d’Amérique, on peut néanmoins y voir, au-delà de la prise en compte de la souffrance des victimes, des méthodes relevant davantage de l’ordre de l’ethnocide que du génocide. La différence entre ces deux derniers concepts se situe non pas dans le nombre de victimes - incalculable dans les deux cas - ni dans l’objectif ultime – identique - mais dans les moyens. Si le terme de « génocide » définit la destruction physique des peuples, celui d’« ethnocide » décrit pour sa part la destruction des différences culturelles, « la dissolution du multiple dans l’Un », comme l’indique Pierre Clastres. Cet article propose d’explorer les arguments utilisés dans cette controverse en tentant de démêler ce qui relève de la recherche légitime d’une reconnaissance juridique de la souffrance et de la mémoire, de ce qui relève tout aussi légitimement d’une analyse

  8. Development of a bio-mechanical model of the spine based on 3D internal-external relationships: bi-planar radiography and Moire fringes; Developpement d'un modele biomecanique du rachis base sur les relations 3D internes - externes: radiographie bi-planaire et franges de Moire

    Nowadays, radiography is the gold standard for the follow up of spinal pathologies. Furthermore, bi-planar radiography allows the assessment of vertebrae configuration, by 3-dimensional (3D) reconstruction. However, multiple radiographic examinations during childhood and adolescence increase the risk of breast cancer among women. To reduce radiation doses, some radiographic assessments could be replaced by the back surface evaluation. This kind of non-invasive procedure allows for acquisition of many clinical parameters useful for spinal pathologies diagnosis and follow-up. Moreover, with an appropriate bio mechanical model, the back surface measurements could be used to estimate the spine configuration. The aim of this thesis is to develop and implement such a model based on personalized internal and external data. The Biomod 3S device has been developed by the company AXS MEDICAL SAS, Bordeaux, France. It offers the possibility of simultaneous acquisitions of X-rays and Moire fringes to obtain 3D reconstructions of the spine and the back surface. Such acquisitions on fifteen scoliotic subjects have enabled us to assess several relationships between internal 3D parameters (for example axial rotation of vertebrae) and external 3D parameters (for example rib hump). The spine configuration and the back surface obtained during this acquisition will also be used as initial position to develop (with Scilab) the multi-body model. The other data used by the model are the back surface in a second position and constraints obtained from the surface in both positions (for example displacement of C7 vertebra). The model has been validated on nine healthy subjects, whose 3D spine and back surface were reconstructed in several positions (standing, leaning forward, sitting) from MRI acquisitions. Moreover, the model has been operated on a pathological subject. This work has explored and utilized many spine and back surface information and leads the way to non-invasive diagnosis

    This document is the summative report on the ENCOAL Mild Coal Gasification Project. It covers the time period from September 17, 1990, the approval date of the Cooperative Agreement between ENCOAL and the US Department of Energy (DOE), to July 17, 1997, the formal end of DOE participation in the Project. The Cooperative Agreement was the result of an application by ENCOAL to the DOE soliciting joint funding under Round III of the Clean Coal Technology Program. By June 1992, the ENCOAL Plant had been built, commissioned and started up, and in October 1994, ENCOAL was granted a two-year extension, carrying the project through to September 17, 1996. No-cost extensions have moved the Cooperative Agreement end date to July 17, 1997 to allow for completion of final reporting requirements. At its inception, ENCOAL was a subsidiary of Shell Mining Company. In November 1992, Shell Mining Company changed ownership, becoming a subsidiary of Zeigler Coal Holding Company (Zeigler) of Fairview Heights, Illinois. Renamed successively as SMC Mining Company and then Bluegrass Coal Development Company, it remained the parent entity for ENCOAL, which has operated a 1,000-ton/day mild coal gasification demonstration plant near Gillette, Wyoming for nearly 5 years. ENCOAL operates at the Buckskin Mine owned by Triton Coal Company (Triton), another Zeigler subsidiary.

    Background: The "July effect" is the potential effect that new and recently promoted residents have on patient care during the first months of the academic year. Literature suggests that the July effect may worsen patient outcomes and lead to systemic inefficiencies. Objective: We evaluate the July effect on mortality, morbidity, and efficiency outcomes in patients undergoing radical cystectomy. Methods: A chart review was performed in patients who underwent radical cystectomy between January 2008 and April 2012. Demographic information was abstracted from patient charts and outcomes compared between operations performed in July, September, and November (first month of each resident's university rotation) to the remainder of the year. Outcomes of interest included mortality, complications, and markers of efficiency (operative time, length of hospital stay, and estimated blood loss). Results: Two hundred and fifty one patients were included in the analysis. There were no major differences in mortality or morbidity between the July, September, November group and the rest of the year. Multivariable analysis demonstrates a trend for operations performed in the months of July, September, and November to be associated with longer OR times 2.06 (0.99-4.27), p = 0.053. Length of hospital stay and estimated blood loss were no different between the two groups. Conclusions: These data demonstrate no increase in mortality or morbidity during the early academic period. Additionally, while there is a trend for OR time to be longer in the early group, length of hospital stay and estimated blood loss were no different. These data may be used as an impetus to continue to investigate technical/clinical teaching practices, strategies to assess resident progression, and to initiate protocols to support residents early in the academic year in efforts to prevent inefficiencies.

    Full Text Available Quelle sont les traces laissées par la guerre d’Algérie dans les textes produits par les écrivains issus de l’immigration ? Telle est la question principale que pose cet article. Cependant, loin de se contenter de répertorier les différents modes d’inscription de la guerre dans des œuvres aux statuts variés – du récit-témoignage à la fiction, en passant par l’autobiographie –, cet article analyse d’une part la façon dont l’écrivain remodèle le passé communautaire ou familial et, du même coup, forge une mémoire et la transmet à ses lecteurs. D’autre part, il questionne également la visée de ces mises en récit qui, tantôt, optent pour le quasi-effacement de la violence, tantôt au contraire, tentent d’écrire des événements demeurés longtemps enfouis, comme refoulés de la mémoire française.¿Qué huellas ha dejado la guerra de Argelia en los textos de los escritores procedentes de la immigration? Tal es la pregunta que plantea este artículo. Sin embargo, no se limita a catalogar los modos de inscripción de la guerra en obras con características formales diferentes – desde el relato testimonial hasta la ficción, pasando por la autobiografía – sino que por una parte analiza cómo el escritor recompone el pasado comunitario o familiar y, al mismo tiempo, crea una memoria y la transmite a los lectores. Por otra parte, estudia también el objetivo de estos relatos, que a veces optan por una desaparición prácticamente total de la violencia, y otras veces, intentan describir acontecimientos que han permanecido ocultados durante mucho tiempo, como si hubieran sido expulsados de la memoria francesa.What are the traces left by the war of Algeria in narratives written by second-generation immigrant authors? Such is the main question raised by this article. However, far from only listing the different modes of inscription of the war in works of various statutes (story-testimony, fiction, and

    Directory of Open Access Journals (Sweden)

    Nathalie Vincent-Arnaud

    2010-11-01

    Full Text Available Poète américain contemporain, auteur de nombreux recueils dont l’éclectisme souligne son goût pour le franchissement des frontières géographiques et culturelles, James A. Emanuel fait figure de passeur entre l’art poétique et l’art musical comme en témoigne sa collaboration étroite avec des musiciens de jazz depuis une quinzaine d’années. Décrivant volontiers son activité poétique récente comme « des ponts jetés entre musique et poésie », revendiquant la paternité du genre du « jazz and blues and gospel haiku » dont la pratique s’est affirmée et systématisée dans son recueil Jazz from the Haiku King paru en 1999, il paraît ainsi s’inscrire de plein droit dans la tradition des poètes jazz initiée par un Kerouac ou un Burroughs au cours de la période particulièrement riche dans ce domaine de la Beat Generation.Consacré à l’exploration de l’« anatomie du jazz » à travers l’évocation d’une myriade de figures du jazz, du gospel et du blues – de Louis Armstrong à Sonny Rollins en passant par Cab Calloway, Ray Charles et Mahalia Jackson – le recueil est avant tout conçu comme le parcours de reconnaissance d’une mémoire culturelle. Au fil de ces « routes du jazz » – autoroutes soigneusement balisées ou chemins de traverse plus obscurs – qu’il met en scène, se trouvent peu à peu dévoilées les diverses facettes de la tension omniprésente entre la mémoire spécifique d’un peuple et l’élargissement à l’universel d’un art complexe qui fait résonner la symbiose de divers modes d’expression identitaire.Le présent article a pour but de montrer comment ces poèmes, au carrefour du linguistique et du musical, tissent une toile de fond identitaire des plus foisonnantes qui, œuvrant à la redéfinition d’un genre, confère à ce dernier de nouveaux et féconds points de résonance.

    2009-09-01

    We report the analysis of images obtained by the contributors to the International Outer Planet Watch (IOPW) of the debris left in the atmosphere of Jupiter by the object that impacted the planet between 18 and 19 July 2009. The discovery images by Anthony Wesley in July 19.625 and the first two days of its tracking, shows a dark debris spot (continuum wavelength) located at planetocentric latitude -55.1 deg and 304.5 deg System III longitude. The imaging survey indicates that the spot was not present in July 18.375, so the impact occurred during a window between both dates. The main spot had a size of about 4,500 km and to its Northwest a thin debris halo of similar size was initially observed. Methane band images at a wavelength of 890 nm shows the spot to be bright indicating that the debris aerosols are highly placed in the atmosphere relative to surrounding clouds. At the central latitude of the impact, the Jovian flow has nearly zero speed but anticyclonic vorticity bounded by jets at -51.5 deg (directed westward with velocity -10 m/s) and at -57.5 deg (directed eastward with velocity 25 m/s). The morphology in the continuum and the spot brightness in the methane band strongly suggest that the feature was caused by a cometary or asteroidal impact, similar in behaviour to the SL9 impacts of 1994.

    1980-09-25

    This interim report summarizes results from the Tandem Mirror Experiment (TMX) during the period January to July 1980 and describes the physics experiments, the machine operation, and the diagnostics that were added to TMX during this period. This operating period followed the initial proof-of-principle TMX experiments and predated the ongoing final experiments preceding TMX shutdown for modification to TMX Upgrade. The results described in this report include measurements of plasma parameters and plasma behavior which confirm the initial TMX results that demonstrated that the tandem mirror configuration can be generated and sustained by neutral beam injection and that the tandem mirror configuration improves confinement of magnetic mirror systems.

    The maximum entropy method has been applied in the spectral analysis of high-energy cosmic-ray intensity during the large Forbush event of July 13, 1982. An oscillation with period of about 2 hours and amplitude of 1 to 3% was found to be present during the decrease phase. This oscillation can be related to a similar periodicity in the magnetospheric field. However, the variation was not observed at all neutron monitor stations. In the beginning of the recovery phase, the intensity oscillated with a period of about 10 hours and amplitude of 3%.

    Southern Europe (Italy and the surrounding countries) experienced an unusual wet summer in 2014. The monthly rainfall in July 2014 was 84% above (more than three standard deviation) normal with respect to the 1982-2013 July climatology. The heavy rainfall damaged agriculture, and affected tourism and overall economy of the region. In this study, we tried to understand the physical mechanisms responsible for such abnormal weather by using model and observed datasets. The anomalously high precipitation over Italy is found to be associated with the positive sea surface temperature (SST) and convective anomalies in the tropical Pacific through the atmospheric teleconnection. Rossby wave activity flux at upper levels shows an anomalous tropospheric quasi-stationary Rossby wave from the Pacific with an anomalous cyclonic phase over southern Europe. This anomalous cyclonic circulation is barotropic in nature and seen extending to lower atmospheric levels, weakening the seasonal high and causing heavy precipitation over the Southern Europe. The hypothesis is verified using the National Centers for Environmental Prediction (NCEP) coupled forecast system model (CFSv2) seasonal forecasts. It is found that two-month lead forecast of CFSv2 was able to capture the wet summer event of 2014 over Southern Europe. The teleconnection pattern from Pacific to Southern Europe was also forecasted realistically by the CFSv2 system.

    On 23 July 2012 a significant and rapid coronal mass ejection (CME) was detected in situ by the Solar Terrestrial Relations Observatory (STEREO) A. This CME was unusual due to its extremely brief Sun-to-1 AU transit time of less than 21 h and its exceptionally high impact speed of 2246 km/s. If this CME had been Earth directed, it would have produced a significant geomagnetic storm with potentially serious consequences. To protect our ground- and space-based assets, there is a clear need to accurately forecast the arrival times of such events using realistic input parameters and models run in near real time. Using Wang-Sheely-Arge (WSA)-Enlil, the operational model currently employed at the NOAA Space Weather Prediction Center, we investigate the sensitivity of the 23 July CME event to model input parameters. Variations in the initial CME speed, angular width, and direction, as well as the ambient solar wind background, are investigated using an ensemble approach to study the effect on the predicted arrival time of the CME at STEREO A. Factors involved in the fast transit time of this large CME are discussed, and potential improvements to modeling such events with the WSA-Enlil model are presented.

    Lagi, Marco; Bar-Yam, Yaneer

    2012-01-01

    Recent droughts in the midwestern United States threaten to cause global catastrophe driven by a speculator amplified food price bubble. Here we show the effect of speculators on food prices using a validated quantitative model that accurately describes historical food prices. During the last six years, high and fluctuating food prices have lead to widespread hunger and social unrest. While a relative dip in food prices occurred during the spring of 2012, a massive drought in the American Midwest in June and July threatens to trigger another crisis. In a previous paper, we constructed a model that quantitatively agreed with food prices and demonstrated that, while the behavior could not be explained by supply and demand economics, it could be parsimoniously and accurately described by a model which included both the conversion of corn into ethanol and speculator trend following. An update to the original paper in February 2012 demonstrated that the model previously published was predictive of the ongoing pric...

    This paper reports on the orbit determination performance for the Cassini spacecraft from July 2008 to December 2011. During this period, Cassini made 85 revolutions around Saturn and had 52 close satellite encounters. 35 of those were with the massive Titan, 13 with the small, yet interesting, Enceladus as well as 2 with Rhea and 2 with Dione. The period also includes 4 double encounters, where engineers had to plan the trajectory for two close satellite encounters within days of each other at once. Navigation performance is characterized by ephemeris errors relative to in-flight predictions. Most Titan encounters 3-dimensional results are within a 1.5 formal sigma, with a few exceptions, mostly attributable to larger maneuver execution errors. Results for almost all other satellite encounter reconstructions are less than 3 sigma from their predictions. The errors are attributable to satellite ephemerides errors and in some cases to maneuver execution errors.

    We utilize our three-dimensional Storm Electrification Model with an explicit lightning scheme and chemistry to simulate the 12 July 1996 thunderstorm that occurred in northeastern Colorado during the Stratospheric-Tropospheric Experiment: Radiation, Aerosols and Ozone (STERAO) Deep Convection Field Project. The NO production is based on the energy dissipation of the lightning discharge with a pressure dependence included. The chemistry module has nine species, including NO, NO2, O3, and CH4, but does not include non-methane hydrocarbons. There are eighteen reactions among the nine species, three of which are photolytic. We focus on the production of NOx (NO + NO2) by lightning within the model and compare our results to airborne measurements obtained during the thunderstorm.

    A tsunami earthquake (Mw = 7.7) occurred south of Java on 17 July 2006. The event produced relatively low levels of high-frequency radiation, and local felt reports indicated only weak shaking in Java. There was no ground motion damage from the earthquake, but there was extensive damage and loss of life from the tsunami along 250 km of the southern coasts of West Java and Central Java. An inspection of the area a few days after the earthquake showed extensive damage to wooden and unreinforced masonry buildings that were located within several hundred meters of the coast. Since there was no tsunami warning system in place, efforts to escape the large waves depended on how people reacted to the earthquake shaking, which was only weakly felt in the coastal areas. This experience emphasizes the need for adequate tsunami warning systems for the Indian Ocean region.

    1989-08-01

    The purpose of this report is to provide management with performance data on key performance indicators selected from the FFTF Early Warning System performance indicators. Very good performance for the month of July was highlighted by continuos full power operation for the entire month and by extremely low plant personnel radiation exposure during the second quarter of 1989. In spite of increased effort this month, the corrective maintenance work off rate continued to rise. Increased FFTF resource efforts will continue on this indicator as well as Other Performance Indicators which reflect undesirable trends. Increased Westinghouse Hanford Company emphasis continues to be placed on improving the Operations staffing levels. Extensive use of overtime and support shift personnel is still being required to support extra work loads imposed by non-routine evolutions.

    Since the 1988 launch of global poliomyelitis eradication efforts, four of the six World Health Organization (WHO) regions have been certified polio-free. Nigeria is one of only three countries, along with Afghanistan and Pakistan, where transmission of wild poliovirus (WPV) has never been interrupted. During 2003-2013, northern Nigeria served as a reservoir for WPV reintroduction into 26 previously polio-free countries. In 2012, the Nigerian government launched a national polio eradication emergency plan to intensify efforts to interrupt WPV transmission. This report describes polio eradication activities and progress in Nigeria during January 2014-July 2015 and updates previous reports. No WPV cases have been reported to date in 2015, compared with a total of six cases reported during 2014. Onset of paralysis in the latest reported WPV type 1 (WPV1) case was July 24, 2014. Only one case of circulating vaccine-derived poliovirus type 2 (cVDPV2) has been reported to date in 2015, compared with 20 cVDPV2 cases during the same period in 2014. Pending final laboratory testing of 218 remaining specimens of 16,617 specimens collected since January 2015, Nigeria could be removed from the WHO list of polio-endemic countries in September 2015. Major remaining challenges to the national polio eradication program include sustaining political support and program funding in the absence of active WPV transmission, maintaining high levels of population immunity in hard-to-reach areas, and accessing children in security-compromised areas of the northeastern states.

    TWINS is the first mission to perform stereo imaging of the Earth's ring current. The magnetic storm on 22 July 2009 is the largest storm observed since TWINS began routine stereo imaging in June 2008. On 22 July 2009, the Dst dropped to nearly -80nT at 7:00 and 10:00 UT. During the main phase and at the peak of the storm, TWINS 1 and 2 were near apogee and moving from pre-dawn to post-dawn local time. The energetic neutral atom (ENA) imagers on the 2 spacecraft captured the storm intensification and the formation of the partial ring current. The peak of the ENA emissions was seen in the midnight-to-dawn local-time sector. The development of this storm has been simulated using the Comprehensive Ring Current Model (CRCM) to understand and interpret the observed signatures. We perform CRCM runs with constant and time-varying magnetic field. The model calculations are validated by comparing the simulated ENA and ion flux intensities with TWINS ENA images and in-situ ion data from THEMIS satellites. Simulation with static magnetic field produces a strong shielding electric field that skews the ion drift trajectories toward dawn. The model's corresponding peak ENA emissions are always eastward than those in the observed TWINS images. On the other hand, simulation with a dynamic magnetic field gives better spatial agreements with both ENA and insitu particle data, suggesting that temporal variations of the geomagnetic field exert a significant influence upon global ring current ion dynamics.

    TWINS is the first mission to perform stereo imaging of the Earth's ring current. The magnetic storm on 22 July 2009 was at the time the largest storm observed since TWINS began routine stereo imaging in June 2008. On 22 July 2009, the Dst dropped to nearly .80 nT at 0700 and 1000 UT. During the main phase, and at the peak of the storm, TWINS 1 and 2 were near apogee and moving between predawn and postdawn local time. The energetic neutral atom (ENA) imagers on the two spacecraft captured the storm intensification and the formation of the partial ring current. The peak of the high-altitude ENA emissions was seen in the midnight-to-dawn local time sector. The development of this storm has been simulated using the comprehensive ring current model (CRCM) to understand and interpret the observed signatures. We perform CRCM runs with constant and time-varying magnetic field. The model calculations are validated by comparing the simulated ENA and ion flux intensities with TWINS ENA images and in situ ion data from a THEMIS satellite. Simulation with a static magnetic field produces a strong shielding electric field that skews the ion drift trajectories toward dawn. The model's corresponding peak ENA emissions are always more eastward than those in the observed TWINS images. On the other hand, the simulation with a dynamic magnetic field gives better spatial agreement with both ENA and in situ particle data, suggesting that temporal variations of the geomagnetic field exert a significant influence upon global ring current ion dynamics.

    Full Text Available The influence of the solar proton event (SPE 14–16 July 2000 on Polar Mesosphere Summer Echoes (PMSE is examined. PMSE were observed by the Esrange VHF MST Radar (ESRAD at 67°53'N, 21°06'E. The 30MHz Imaging Riometer for Ionospheric Studies IRIS in Kilpisjärvi (69°30'N, 20°47'E registered cosmic radio noise absorption caused by ionisation changes in response to the energetic particle precipitation. An energy deposition/ion-chemical model was used to estimate the density of free electrons and ions in the upper atmosphere. Particle collision frequencies were calculated from the MSISE-90 model. Electric fields were calculated using conductivities from the model and measured magnetic disturbances. The electric field reached a maximum of 91mV/m during the most intensive period of the geomagnetic storm accompanying the SPE. The temperature increase due to Joule and particle heating was calculated, taking into account radiative cooling. The temperature increase at PMSE heights was found to be very small.

    The observed PMSE were rather intensive and extended over the 80–90km height interval. PMSE almost disappeared above 86km at the time of greatest Joule heating on 15 July 2000. Neither ionisation changes, nor Joule/particle heating can explain the PMSE reduction. Transport effects due to the strong electric field are a more likely explanation.

    Full Text Available Cet article porte sur les tensions que provoque, dans une petite ville touristique de l’arrière-pays azuréen, l’entreprise mémorielle dans laquelle s’est lancée une association désireuse d’établir et de publiciser une histoire de l’immigration locale en provenance des pays du Maghreb. L’enquête montre ce que ces tensions doivent à l’entrechoquement de trois mémoires : celle qui célèbre le passé patrimonial d’une localité qui trouve là une ressource dans la fabrication d’une image touristique fondée sur l’ “authenticité” ; celle de ces “immigrés” vençois dont la contribution à l’histoire de la ville n’a jamais été publiquement reconnue ; celle de l’association elle-même qui, à cette occasion, se trouve confrontée à son propre passé d’association militante devenue au fil du temps un partenaire des autorités dans la mise en œuvre des politiques sociales.This article deals with the tensions provoked, in a small tourist-oriented city of the French Riviera back country, by a memorial project undertaken by an association seeking to establish and publicize a history of local immigration from countries of the Maghreb. The investigation shows what these tensions owe to the clash of three sources of remembrance : one celebrating the patrimonial past of a locality finding therein a resource for fabricating a touristic image founded on “authenticity” ; another, that of the Vence “immigrants”, whose contribution to the city’s history has never been publicly recognized ; and, finally, that of the association itself which, on this occasion, is confronted with its own past as a militant association, having become over time a partner of local authorities in the implementation of social policies.

    This report covers the work performed from July 1984 to July 1987 under the project entitled ''Weathering Effects on Structure and Reactivity of US Coals'' (grant number FG22-84PC70798). The main objectives of the study were to investigate the structural changes in coal during the weathering process as well as to develop a simple, reliable weathering index, which can monitor indirectly the weathering-induced changes in physical and chemical properties. Although there have been numerous publications on structure and reactivity of coal, most data reported in the literature thus far have been obtained on coal samples of uncertain weathering status and therefore need to be interpreted with great caution. Weathering has a profound effect on many important coal properties such as heating value, caking characteristics, acidity, flotability and reactivity in liquefaction, combustion and gasification processes. The objective of developing a weathering index is to predict these coal property changes due to weathering without resorting to real-time measurements or pilot plant runs. This report is comprised of four main chapters: I. Structural Changes due to Weathering; II. Material Balance in Weathering Process; III. Development of a Reliable Weathering Index; and IV. Proposed Weathering Mechanisms. A battery of sophisticated analytical tools and techniques was employed during this study. Pyrolysis mass spectrometry in time-integrated, as well as in time-resolved modes with computer-aided data analysis techniques (such as factor and discriminant analysis), gas chromatography, thermogravimetry/mass spectrometry and solvent extraction were used for determining the role of oxygen during the weathering process. Pyrolysis mass spectrometry, Free Swelling Index and a novel slurry pH technique were employed as weathering indicators. 170 refs.

    Convective storms on the evening of July 21, 2015 generated a number of debris flows on the SE flank of Mount Shasta Volcano, Shasta-Trinity National Forest. Widespread rilling, gullying and sheet erosion occurred throughout the affected area. These storms damaged roads by scouring drainage ditches, blocking culverts, eroding road prisms, and depositing debris where streams emerged from their incised channels and flowed over their alluvial fans. Effects were limited geographically to a narrow band about 6 miles wide trending in a northeasterly direction. Debris flows were identified at Pilgrim Creek and nearby channels, and Mud Creek appears to have experienced sediment laden flows rather than debris flows. Doppler radar data reveal that the storm cells remained nearly stationary for two hours before moving in a northeasterly direction. Debris flows triggered by convective storms occur often at Mount Shasta, with a similar event recorded in 2003 and a larger one in 1935, which also involved glacial melt. The 1935 debris flow at Whitney Creek buried Highway 97 north of Weed, CA, and took out the railroad above the highway. In September, 2014, a large debris flow occurred in Mud Creek, but it was associated solely with glacial melt and was not accompanied by rain. The 2014 event at Mud Creek filled the channel and parts of the floodplain with debris. This debris was in turn reworked and eroded by sediment laden flows on July 21, 2015. This study was initiated in August, 2015, and began with field inventories to identify storm effects. Lidar data will be used to identify possible avulsion points that could result in unexpected flash flooding outside of the main Mud Creek channel and on adjacent streams. The results of this study will provide critical information that can be used to assess flash flood risk and better understand how to manage those risks. Finally, some conclusions may be drawn on the kinds of warning systems that may be appropriate for possible flash

    Having already performed a lengthy cosmic ray test run, ALICE decided to immediately start consolidation work after the shutdown last autumn. “We wanted to use the additional time for improvements and upgrades," explains Paul Kuijer, ALICE Deputy Spokesperson, “for example, we realised that the access to the main tracking device, the TPC, was rather difficult, which could lead to unreasonably long service and repair times in the future, so we spent a lot of time moving all the cabling of the inner tracking system to give more space and better access.” This was a major operation, running from October 2008 until July 2009. All cables and services have been re-tested and the inner tracking system is again on-line. Future maintenance was pre-empted in other areas too, such as replacing a number of capacitors on the time projection chamber (TPC), which were suspected to have a reduced lifetime. The shutdown also gave ALICE the chance to install several new detector systems that were originally scheduled for ...

    The geotechnical data from the underground excavations at the WIPP are interpreted and presented in this Geotechnical Analysis Report. The data are used to characterize conditions, assess design assumptions, and understand and predict the performance of the underground excavations during operations. The data are obtained as part of a regular monitoring program. They do not include data from tests performed by Sandia National Laboratories, the Scientific Advisor to the project in support of performance assessment studies. Geotechnical Analysis Reports have been prepared routinely and made available to the public since 1983. During the Site and Preliminary Design Validation Program, the Architect/Engineer for the project produced the reports on a quarterly basis to document the geomechanical performance during and immediately after construction of the underground. Upon completion of the constriction phase of the project in 1987, the reports have been prepared annually by the Management and Operating Contractor for the facility. This report describes the performance and conditions of selected areas from July 1, 1994, to June 30, 1995.

    2016-01-01

    Four years after the historic announcement of the discovery of the Higgs boson at CERN, a collaboration between INFN and CERN has declared 4 July 2016 “Higgs Boson Pizza Day”.    The Novae Restaurant 1 at CERN will offer two special “Higgs Boson Pizzas” (one vegetarian and one ham and cheese), from 11.30 a.m. to 2.15 p.m., for the usual pizza price. The idea was born in Naples (where else?), the hometown of Pierluigi Paolucci, who - while chatting with INFN president Fernando Ferroni - realised the striking resemblance between Higgs boson event displays and the delicious pizzas in front of them. A specially designed pizza was then created by the chef of the historic “Ettore” pizzeria in St. Lucia, in time for the opening of an Art&Science exhibition on 15 September 2015 in Naples. The owner of the restaurant, Ms Iolanda Canale, has been invited by INFN to come to CERN and help Novae in the preparation of 400 pizzas on thi...

    In this work we analyze the development of a severe-convective-storm system in northwestern Bulgaria on 20 July 2011 which exhibited derecho-like characteristics. Prior to this event, a derecho had never been documented in Bulgaria. The convective system was associated with a cold front. We present a synoptic-scale analysis of the evolution of the cold front and an overview of the wind and the damage that has occurred in the region with the strongest impact. The convective system consisted of two multi-cell thunderstorms that are analyzed in some detail, based on radar data. The two storms merged and the convective system evolved into a bow-shape reflectivity structure with two rear inflow notches. The analysis of the radar data revealed cloud top heights of 17 km, with the formation of а bounded weak echo region, a maximum radar reflectivity factor of 63 dBZ, and wind speeds above 30 m/s. The field investigation revealed patterns in the damaged crops typical of strong wind gusts.

    Full Text Available Welcome to the July 2005 issue of Portal, a special issue with the title ‘Strange Localities: Utopias, Intellectuals and Identities in the 21st Century,’ guest edited by Alistair Fox and Hilary Radner (both from the University of Otago, New Zealand, who convened an international colloquium on this theme in January 2004, and Murray Pratt (University of Technology Sydney, Australia. As Alistair Fox says in his introduction to the special issue, the twelve papers gathered under the ‘Strange Localities’ rubric provide rich insights into the ways by which ‘the contemporary utopian impulse is expressing itself, both in the search for utopia, and through the exposure of false utopias.’ With a broad geographical reach, and an equally broad critical gaze, the essays collected here shed new light on the critical, yet often ambivalent, role that identity politics play in myriad utopian projects, and also in such critical enterprises and epoch-defining processes as postcolonialism, postfeminism, postmodernism, transnationalism, multiculturalism, and economic and cultural globalization. In addition to the papers collected in the special issue section, this issue of Portal includes a number of essays that, while not addressing the special issue theme, also have much to say about the nexus between contemporary identity debates, intellectual practice, and utopian imaginaries. We are also pleased to introduce in the Portal Cultural Works' section two short chronicle-like pieces by Moses Iten, a young Australian writer. Paul Allatson, Chair, PORTAL Editorial Committee

    The key article in this volume of the LLE Review, covering July-September 2004, addresses "Shock Propagation in Deuterium-Tritium-Saturated Foam" by T. J. B. Collins (LLE) and A. Poludnenko, A. Cunningham, and A. Frank (UR, Department of Physics and Astronomy) (p. 227). Testing the assumption of homogeneous mixing in fibrous foams saturated with cryogenic deuterium and tritium, shock passage in wetted-foam mixtures was simulated by the adaptive-mesh, two-dimensional hydrodynamic code AstroBEAR. For foam fibers of diameter ~1/10 µm and relevant foam densities, the mixing length behind the shock is found to be of the order of microns. Transverse motion dampens out sufficiently that, at the mixing region's edge farthest from the shock, Rankine-Hugoniot jump conditions are obeyed to within a few percent and shock speeds are also within a few percent of their homogeneous values. In addition, questions of feedthrough and feedout are addressed, showing that the stability of the shock front, once it leaves the wetted-foam layer, minimizes the effect of feedthrough. As a result, simulations of whole-foam-pellet implosions may model the wetted foam as a homogeneous mixture.

    During the ICTIOALBORAN-0793 multidisciplinary oceanographic survey carried out in July 1993 by the Instituto Español de Oceanografı´a (IEO) in the Alboran Sea, some anomalous features were detected. One was the presence of a small cyclonic eddy in the western Alboran Basin, close to the African coast. The upper layer of the eddy consisted of Mediterranean Surface Water and was separated from its supposed source (the northern Alboran Sea) by the Atlantic Jet. Another feature was the probable temporary interruption of the flow of fresh Atlantic Water (S≈36.5) into the eastern Alboran Basin and its replacement by a modified (saltier) Atlantic Water. These features can be explained assuming a time evolution of the surface circulation in the Alboran Sea forced by speed variations in the inflowing Atlantic Water through the Strait of Gibraltar. A collection of satellite images covering the survey period and across-strait sea level difference data, indicative of the geostrophic velocity of the inflow through the Strait, were used to check this assumption. Both sets of data supplied independent but compatible information in the sense that they complemented each other and gave support to the proposed evolving model. Finally, some speculative ideas attempting to correlate the inferred variability in the Alboran Sea with the state of the baroclinic water exchange through the Strait of Gibraltar (maximal or submaximal) are discussed.

    Short, R.W. [ed.

    1992-12-31

    This volume of the LLE Review, covering the period July--September 1992, contains articles on methods of balancing the beam power on the OMEGA Upgrade and on the damping of ion-sound waves in laser-produced plasmas. The advanced technology section includes reports on optical nonlinearities in high-temperature superconductors, a method of increasing gas retention time for laser-fusion targets, and a study of stimulated Raman scattering of laser beams in air. Highlights of the research reported in this issue are: An efficient method has been developed for balancing the power in the 60 beams of the OMEGA Upgrade. The method can achieve 2% power balance for both main and foot beams using only four system shots. A study of ion-sound-wave damping has substantially revised and expanded our knowledge of this effect. The damping of ion waves can have important consequences for laser-plasma interaction. The use of femtosecond laser pulses to study the properties of thin-film, high-temperature superconductors is discussed. A method for increasing the gas retention time of polymer-shell laser-fusion targets by overcoating them with a thin layer of aluminum is described. A code has been developed to study stimulated rotational Raman scattering in high-power laser beams propagating through air.

    This volume of the LLE Review, covering July-September 2001, features an article by C. Stoeckl, V. Yu. Glebov, J. D. Zuegel, and D. D. Meyerhofer (p. 171) that describes a simple, low-cost, wide dynamic-range, neutron bang time (NBT) detector. This instrument complements the capabilities of the streak camera-based neutron temporal diagnostic (NTD), which is also installed on the OMEGA laser. The new NBT measures the neutron bang time of D2- and DT-filled inertial confinement fusion (ICF) implosion capsules at neutron yields between 107 and 1011 with an absolute timing accuracy of better than100 ps. This level of accuracy allows the modeling of the implosions to be effectively guided using hydrocode calculations.

    Short single-stranded DNA (or RNA) molecules can be designed to have several long lived (> hours) secondary structures. In principle, such molecules could be used as nanomemories if they could be easily induced to switch between trapped states. We propose here that the necessary work required to drive the molecule into one particular trapped state can be provided by its own synthesis. Following this idea, we argue that a low voltage (<1 V) may induce a bistable DNA molecule to switch structure at will, by forcing it to thread through a nanopore and refold alternatively from either of its ends.

    1998-09-01

    This volume of the LLE Review, covering the period July-September 1998, includes reports on two of the newest subsystems in the OMEGA laser facility. A. V. Okishev, M. D. Skeldon, and W. Seka have developed a highly stable, diode-pumped Nd:YLF master oscillator for the OMEGA laser system. This new master oscillator produces either single-frequency Q-switched pulses or cw radiation for the OMEGA pulse-shaping system. The switch-over between these two regimes requires no laser realignment. The new master oscillator is completely computer controlled and has been operating continuously in OMEGA for six months without operator intervention. A. Babushkin, W. Bittle, S. A. Letzring, M. D. Skeldon, and W. Seka have designed a negative-feedback–controlled regenerative amplifier that has been part of the OMEGA laser system for the past two years. The negative feedback makes the energy output of the regenerative amplifier stable and insensitive to the variations in pulse energy. This amplifier’s long-term output energy stability is the highest ever demonstrated for a millijoule-level laser system, either flashlamp pumped or diode pumped. Other articles in this volume are titled: Transcient Bandwidth Analysis of Photoconductive Microwave Switches Implemented in the OMEGA Pulse-Shaping System; Simulations of Near-Field Intensity Modulations in High-Intensity Laser Beams due to Self- and Cross-Phase Modulation Between Orthogonally Polarized Laser Beams Emerging from a Diamond-Turned KDP Wedge; X-Ray Radiographic System Used to Measure the Evolution of Broadband Imprint in Laser-Driven Planar Targets; Collisionless Damping of Localized Plasma Waves in Laser-Produces Plasmas and Application to Stimulated Raman Scattering in Filaments; LLE's Summer High School Research Program; FY98 Laser Facility Report; and, National Laser Users' Facilty News.

    This volume of the LLE Review, covering the period July--September 1997, begins with a general introduction to LLE`s experimental physics program and a report on recent results. This article includes a useful summary of the system`s operational capabilities and system parameters. Other highlights of the wide variety of research presented in this issue are: a promising method to directly observe the cold compressed shell of an imploding target. The shell is normally observed by backlighting. The proposal described here is to use a high-Z dopant that fluoresces under radiation from the hot core in the K{alpha} line. A study of the instabilities associated with near-forward stimulated Brillouin scattering. It includes a calculation of the saturation times and steady-state gain exponents. A successful program of pulse shaping for the OMEGA laser system. Examples of a variety of pulse shapes that can be programmed are presented. A description of the angular-scattering characteristics of ferroelectric liquid crystal electro-optical devices operating in transient and extended scattering modes. The possibility of applying these devices as modulators in practical IR imaging systems is evaluated. A faster method of shaping and finishing IR materials by the use of magnetorheological fluids. Detailed specifications and test results are included. An integrated circuit tester based on interferometric imaging. This technique holds promise of ultrafast noninvasive testing of the voltage states of sections of microchips. Continued success of the Laboratory`s High School Summer Research Program. The program, which started in 1989, has brought several dozen young people into intimate contact with modern science and technology. The volume concludes with a Laser Facility Report and the National Laser Users` Facility News.

    This Geotechnical Analysis Report (GAR) presents and interprets the geotechnical data from the underground excavations at the Waste Isolation Pilot Plant (WIPP). The data, which are obtained as part of a regular monitoring program, are used to characterize conditions, to compare actual performance to the design assumptions, and to evaluate and forecast the performance of the underground excavations. GARs have been available to the public since 1983. During the Site and Preliminary Design Validation (SPDV) Program, the architect/engineer for the project produced these reports on a quarterly basis to document the geomechanical performance during and immediately after excavation of the underground facility. Since the completion of the construction phase of the project in 1987, the management and operating contractor for the facility has prepared these reports annually. This report describes the performance and condition of selected areas from July 1, 2001, to June 30, 2002. It is divided into ten chapters. The remainder of Chapter 1 provides background information on WIPP, its mission, and the purpose and scope of the geomechanical monitoring program. Chapter 2 describes the local and regional geology of the WIPP site. Chapters 3 and 4 describe the geomechanical instrumentation located in the shafts and shaft stations, present the data collected by that instrumentation, and provide interpretation of these data. Chapters 5, 6, and 7 present the results of geomechanical monitoring in the three main portions of the WIPP underground facility (the access drifts, the Northern Experimental Area, and the Waste Disposal Area). Chapter 8 discusses the results of the Geoscience Program, which include fracture and stratigraphic mapping, borehole and core logging, and borehole observations. Chapter 9 summarizes the results of the geomechanical monitoring and compares the current excavation performance to the design requirements. Chapter 10 lists the References and Bibliography.

    This volume of the LLE Review, covering the period of July-September 1996, includes a description of an important experiment carried out on OMEGA by researchers from LANL, LLNL, and LLE to demonstrate the feasibility of using OMEGA for indirect drive. Additional topics include tetrahedral hohlraums, the speckle properties of phase- converted laser beams, design criteria for SSD phase modulators, and the design of slab amplifiers. Highlights of the research presented in this issue are (1) Results from the proof-of-principle indirect- drive experiments in which up to 40 OMEGA beams were used to irradiate cylindrical hohlraums. Nova results were reproduced, and new capabilities not available on other lasers were demonstrated. (2) A discussion of tetrahedral hohlraums (spherical hohlraums with four laser entrance holes) as a means of achieving better capsule irradiation uniformity. Tetrahedral hohlraums also allow the use of all 60 OMEGA beams and may provide an alternate route to ignition on the NIF. (3) An analysis of the residual target irradiation nonuniformity due to the fine laser speckle remaining on the beam after being phase converted by the DPP`s. A model shows how a uniformly ablating plasma atmosphere reduces the speckle contribution to the effective time-averaged irradiation nonuniformity. (4) A discussion of the theory, design, manufacture, testing, and implementation of the microwave SSD phase modulators used on OMEGA for two-dimensional SSD. The modulators are capable of operating in the gigahertz frequency range. (5) A discussion of the design and performance of a large-aperture, high-gain Nd:glass zig-zag slab amplifier for materials testing. The design incorporates improvements from previous work in addition to improvements obtained from careful design choices guided by analytic calculations.

    We have observed the 4 July 2010 stellar occultation by Pluto as part of our program of monitoring Pluto's atmospheric changes over the last decade. Successful observations were obtained from three sites: Cerro Calan and Cerro Tololo, Chile, as well as the HESS-project site (High Energy Stereoscopic System) in southwestern Namibia. Successful telescope apertures ranged from 0.45 m to 1.0 m and resulted in seven occultation light curves for the event from among the three sites. Simultaneous analysis of the seven light curves indicates that Pluto's atmosphere continues to be stable, as the calculated atmospheric radii are consistent with those detected in 2006 (Elliot et al., AJ 134, 1, 2007) and 2007 (Person et al., AJ 136, 1510, 2008), continuing the stability that followed the large pressure increase detected between 1988 (Millis et al., Icarus 105, 282, 1993) and 2002 (Elliot et al., Nature 424, 165, 2003). We will present the overall astrometric solution as well as current profiles for Pluto's upper atmospheric temperature and pressure obtained from inversion of the light curves (Elliot, Person, and Qu, AJ 126, 1041, 2003). This work was supported, in part, by grants NNX10AB27G to MIT, NNX08AO50G to Williams College, and NNH08AI17I to the USNO from NASA's Planetary Astronomy Division. The 0.75-m ATOM (Automatic Telescope for Optical Monitoring) light curve was obtained with the generous assistance of the HESS-project staff, arranged by Stefan Wagner and Marcus Hauser of the University of Heidelberg. The 0.45-m Goto telescope at Cerro Calán National Astronomical Observatory, Universidad de Chile, was donated by the Government of Japan. PROMPT (Panchromatic Robotic Optical Monitoring and Polarimetry Telescopes) observations at Cerro Tololo were made possible by the Robert Martin Ayers Science Fund. Student participation was supported in part by NSF's REU program and NASA's Massachusetts Space Grant.

    Lago La Plata dam is located between the municipalities of Naranjito and Toa Alta in north central Puerto Rico, about 5 kilometers south of the town of Toa Alta and about 5 kilometers north of the town of Naranjito. The reservoir impounds the waters of the Rio de La Plata, the Rio Guadiana, and the Rio Ca?as, and is part of the San Juan Metropolitan Water District, which provides about 35 percent of the total water demand for the area (Soler-Lopez and others, 2000). The reservoir has a drainage area of about 469 square kilometers. The dam was constructed in 1974 and is a concrete gravity structure with a normal pool elevation of 52.00 meters above mean sea level (Puerto Rico Electric Power Authority, 1979). During October 1998, the U.S. Geological Survey (USGS), Caribbean Water Science Center, in cooperation with the Puerto Rico Aqueduct and Sewer Authority (PRASA) conducted a bathymetric survey of Lago La Plata to assess the impact of Hurricane Georges on the storage capacity of the reservoir. Between July 17 and 20, 2006, the USGS and the PRASA conducted an additional bathymetric survey of Lago La Plata to update the reservoir storage capacity and determine the reservoir sedimentation rate by comparing the 2006 survey data with the 1998 survey data.. The purpose of this report is to update the reservoir storage capacity, sedimentation rates, and areas of substantial sediment accumulation since 1998. Historical (1974) data are referenced as needed to account for long-term storage capacity loss trends...

    This article presents the World Health Organization's (WHO) recommendations on the use of dengue vaccine excerpted from the WHO position paper on dengue vaccine published in the Weekly epidemiological Record in July 2016 (Dengue vaccine: WHO position paper, 2016) [1]. The current document is the first WHO position paper on dengue vaccination and focuses primarily on the available evidence concerning the only dengue vaccine to have been registered by National Regulatory Authorities. The position paper gives consideration to the epidemiological features of the disease and assesses the potential use of the vaccine for public health benefits. Footnotes to this paper provide a number of core references including references to grading tables that assess the quality of the scientific evidence, and to the evidence-to-recommendation table. In accordance with its mandate to provide guidance to Member States on health policy matters, WHO issues a series of regularly updated position papers on vaccines and combinations of vaccines against diseases that have an international public health impact. These papers are concerned primarily with the use of vaccines in large-scale immunization programmes; they summarize essential background information on diseases and vaccines, and conclude with WHO's current position on the use of vaccines in the global context. This paper reflects the recommendations of the WHO's Strategic Advisory Group of Experts (SAGE) on immunization. Recommendations on the use of this dengue vaccine were discussed by SAGE in April 2016; evidence presented at that SAGE meeting can be accessed at: http://www.who.int/immunization/sage/previous/en/index.html.

    Full Text Available The ability to copy the actions of others is present from birth in both infant humans and chimpanzees and provides a method for the social transmission of knowledge. For this type of learning to have an impact over the long-term, the infant must be able to encode, store, and retrieve the information they receive for use at a later date. Here we review the literature with the deferred imitation paradigm to demonstrate that by at least 6 months of age, human infants are capable of these comparatively advanced cognitive abilities, which are thought to involve the declarative memory system and the hippocampal formation. Across early development there are dramatic changes in the duration over which information can be retained and the ability of infants to retrieve and express their memories in a flexible manner, which enables them to solve new problems. Research with the deferred imitation paradigm therefore provides important insight into our understanding of social and cognitive development as well as brain development.La capacité à imiter les actions des autres existe dès la naissance tant chez le petit humain que chez le jeune chimpanzé, elle est un moyen de transmission sociale de la connaissance. Pour que ce type d’apprentissage ait un impact sur le long terme, le jeune doit être capable de coder, stocker et récupérer l’information qu'il reçoit pour la réutiliser ultérieurement. Nous faisons une revue de la littérature sur l’imitation différée, pour démontrer que dès l’âge de 6 mois, les jeunes humains sont capables d’exprimer ces capacités cognitives relativement avancées dont on pense qu’elles mettent en jeu les systèmes de la mémoire déclarative et la formation hippocampique. Au cours du développement précoce, il existe des variations très marquées de la durée pendant laquelle les informations peuvent être conservées et de la capacité des jeunes à retrouver et à exprimer leurs souvenirs d’une fa

    In order to achieve high-accuracy measurement of the long focal length, a method of measuring long focal length based on Talbot-Moiré effect was studied in this paper, a long focal length test device was established, it included a collimated wavefront generator, a Talbot interferometer and a imaging system. The effect of wavefront aberration on accuracy of focal length was analyzed. Then the distance s from the sample to the grating G1, the space d between grating G1 and grating G2,and angle of two grating lines as influencing factors on accuracy of focal length were analysed. The alignment method to improve the accuracy was proposed. Pentaprism method for the detection of wavefront was introduced, to ensure that the collimated wavefront quality better than a wavelength. The linear grating encoder was used to measure s and calibrate d, to make the accuracy of the distance better than 0.1 mm. A reference reflective concave sphere was used for angle calibration, to make the accuracy of angle better than 0.001o. The experimental results show that the relative error is less than 0.35% when measured focal length is 5 436 mm.%为了实现长焦距的精确测量,基于泰伯莫尔法测量长焦距的原理,构建出了由准直波前发生器、泰伯干涉仪和成像采集系统组成的长焦距测量装置。分析了准直波前畸变对焦距测量精度的影响,用数值分析的方法分析了待测样品到光栅G1的距离s,光栅G1、G2的间距d以及栅线夹角对焦距测量精度的影响。提出了具体的装调方法:用五棱镜法检测波前,保证准直波前质量PV值优于一个波长;用光栅尺位移传感器测量s,标定d,使其精度达到0.1 mm;采用标准反射凹球面法标定光栅夹角,使光栅夹角的装调精度达到0.001º。对焦距为5436 mm的透镜进行实验测量,误差小于0.35%。

    2012-08-01

    Full Text Available La disparition comme mort, rupture et brisure de notre temps historique hante les romans caraïbes et plus particulièrement ceux de Gabriel García Márquez. L’auteur colombien met en évidence la difficulté qu’il y a à raconter une histoire collective, celle de Macondo et plus largement celle de la terre latino-américaine, inavouable parce qu’inséparable de la violence qui préside à la fondation de la cité et à son développement. Ce souvenir inacceptable de la violence originelle se traduit par la thématique de l’amnésie collective qui, dans Cent ans de solitude, frappe le village de Macondo, que cette amnésie traduise le refoulement dans l’oubli du génocide indien, ou celui du massacre des grévistes de la United Fruit Company. L’évocation romanesque des disparitions – disparitions physiques, mais aussi culturelles, puisqu’elles touchent la mémoire, le sommeil et le langage – se fait par des distorsions narratives où la présence du surnaturel se conjugue avec celle du burlesque, dans l’esthétique propre au « réel merveilleux ». Ici, les drames de l’histoire trouvent leurs échos dans la dérision fictionnelle, et par la disparition l’histoire devient littérature…La desaparición como muerte, ruptura, y quiebra de nuestro tiempo histórico atormenta la novela caribeña y en particular la de Gabriel García Márquez. El autor colombiano pone en evidencia la dificultad de contar una historia colectiva, la de Macondo, y más ampliamente la de la tierra latino-americana, inconfesable porque inseparable de la violencia que determina la fundación de la ciudad y su desarrollo. Ese recuerdo inaceptable de la violencia original se traduce por la temática de la amnesia colectiva que, en Cien años de soledad, aflige al pueblo de Macondo. Esa amnesia traduce la inhibición y el olvido tanto del genocidio de los indios, como de la masacre de los huelguistas de la United Fruit Company. La evocaci

L’analyse de variance indique que, quels que soient le sexe et l’âge il n’y a pas de différence. Mais, Alloway (2006 souligne que la MCT verbale évolue avec l’âge. L’analyse de corrélation révèle qu’il y a une corrélation fortement négative lorsqu’on compare les scores obtenus au rappel indicé correct (RICO, à ceux du rappel indicé incorrect (RINONCO et au nombre d’essais (RIESSAIS. Il est donc essentiel que les enseignants et les élèves aient connaissance et appliquent ces données pour permettre d’améliorer les pratiques des enseignants et les performances des élèves.

  17. Geochemistry of Standard Mine Waters, Gunnison County, Colorado, July 2009

    Science.gov (United States)

    Verplanck, Philip L.; Manning, Andrew H.; Graves, Jeffrey T.; McCleskey, R. Blaine; Todorov, Todor; Lamothe, Paul J.

    In many hard-rock-mining districts water flowing from abandoned mine adits is a primary source of metals to receiving streams. Understanding the generation of adit discharge is an important step in developing remediation plans. In 2006, the U.S. Environmental Protection Agency listed the Standard Mine in the Elk Creek drainage basin near Crested Butte, Colorado as a superfund site because drainage from the Standard Mine enters Elk Creek, contributing dissolved and suspended loads of zinc, cadmium, copper, and other metals to the stream. Elk Creek flows into Coal Creek, which is a source of drinking water for the town of Crested Butte. In 2006 and 2007, the U.S. Geological Survey undertook a hydrogeologic investigation of the Standard Mine and vicinity and identified areas of the underground workings for additional work. Mine drainage, underground-water samples, and selected spring water samples were collected in July 2009 for analysis of inorganic solutes as part of a follow-up study. Water analyses are reported for mine-effluent samples from Levels 1 and 5 of the Standard Mine, underground samples from Levels 2 and 3 of the Standard Mine, two spring samples, and an Elk Creek sample. Reported analyses include field measurements (pH, specific conductance, water temperature, dissolved oxygen, and redox potential), major constituents and trace elements, and oxygen and hydrogen isotopic determinations. Overall, water samples collected in 2009 at the same sites as were collected in 2006 have similar chemical compositions. Similar to 2006, water in Level 3 did not flow out the portal but was observed to flow into open workings to lower parts of the mine. Many dissolved constituent concentrations, including calcium, magnesium, sulfate, manganese, zinc, and cadmium, in Level 3 waters substantially are lower than in Level 1 effluent. Concentrations of these dissolved constituents in water samples collected from Level 2 approach or exceed concentrations of Level 1 effluent

  16. BER Science Network Requirements Workshop -- July 26-27,2007

    Energy Technology Data Exchange (ETDEWEB)

    Tierney, Brian L.; Dart, Eli

    2008-02-01

    The Energy Sciences Network (ESnet) is the primary provider of network connectivity for the US Department of Energy Office of Science, the single largest supporter of basic research in the physical sciences in the United States of America. In support of the Office of Science programs, ESnet regularly updates and refreshes its understanding of the networking requirements of the instruments, facilities, scientists, and science programs that it serves. This focus has helped ESnet to be a highly successful enabler of scientific discovery for over 20 years. In July 2007, ESnet and the Biological and Environmental Research (BER) Program Office of the DOE Office of Science organized a workshop to characterize the networking requirements of the science programs funded by the BER Program Office. These included several large programs and facilities, including Atmospheric Radiation Measurement (ARM) Program and the ARM Climate Research Facility (ACRF), Bioinformatics and Life Sciences Programs, Climate Sciences Programs, the Environmental Molecular Sciences Laboratory at PNNL, the Joint Genome Institute (JGI). National Center for Atmospheric Research (NCAR) also participated in the workshop and contributed a section to this report due to the fact that a large distributed data repository for climate data will be established at NERSC, ORNL and NCAR, and this will have an effect on ESnet. Workshop participants were asked to codify their requirements in a 'case study' format, which summarizes the instruments and facilities necessary for the science and the process by which the science is done, with emphasis on the network services needed and the way in which the network is used. Participants were asked to consider three time scales in their case studies--the near term (immediately and up to 12 months in the future), the medium term (3-5 years in the future), and the long term (greater than 5 years in the future). In addition to achieving its goal of collecting and

    2000-12-01

    This volume of the LLE Review, covering July-September 2000, begins with an article by T. R. Boehly, V. N. Goncharov, O. Gotchev, J. P. Knauer, D. D. Meyerhofer, D. Oron, S. P. Regan, Y. Srebro, W. Seka, D. Shvarts, S. Skupsky, and V.A. Smalyuk, who describe measurements of the effect of beam smoothing and pulse shape on imprinting. (Imprinting is defined as the imposition of pressure perturbations on the target by spatial variations in the laser intensity.) A principal result is the observation of reduced levels of imprint with the higher beam smoothing afforded by 1-THz smoothing by spectral dispersion (SSD). Additional highlights of research presented in this issue are: (1) P. W. McKenty, V. N. Goncharov, R. P. J. Town, S. Skupsky, R. Betti, and R. L. McCrory describe calculations of directly driven ignition capsule performance on the National Ignition Facility (NIF). The authors detail how the various contributors to implosion disruption (laser imprint, power imbalance, and target roughness) affect target performance and final gain. The conclusions are obtained by examining the simulated target evolution with the two-dimensional hydrodynamics computer code ORCHID. (2) D. D. Meyerhofer, J. A. Delettrez, R. Epstein, V. Yu.

    Background Some studies have suggested patients who undergo surgery in July have worse outcomes compared to patients treated during other months. The purpose of this study is to compare inpatient morbidity and mortality among patients who underwent adult spinal deformity (ASD) surgery in July with those who underwent surgery in other months. Methods Admission data for patients who underwent ASD surgery were extracted from the Nationwide Inpatient Sample for the years 2002 to 2011. Only adult patients (over 21 years of age) and elective admissions to teaching hospitals were included. A multivariable regression analysis was performed to examine the independent effect of July admissions on overall complications, major complications, and inpatient mortality. Results A total of 27,794 patients were identified, with 2,023 (7.8%) admitted in July and 25,771 (92.2%) in other months. Overall complication rates in July (43.1%) were not different from rates in other months (44.9%, p=0.468). Similarly, major complication rates were similar; 12.9% in July and 12.4% in other months (p=0.764). Mortality was not different between groups (p=0.807). After multivariable analysis, July admissions were not found to increase the odds of developing any complication (OR 0.94; 95% CI, 0.77 - 1.12; p=0.403), major complications (OR 1.04; 95% CI, 0.76 - 1.41; p=0.788) or inpatient mortality (OR 1.35; 95% CI, 0.31 - 5.84; p=0.684). Conclusion In this study of a nationwide database, patients who underwent ASD surgery in July did not have increased odds of developing a complication or inpatient mortality compared to patients admitted in other months.

    Full Text Available The second issue of PORTAL Journal of Multidisciplinary International Studies for 2007 is a special issue with the title Contesting Euro Visions, guest edited by Dimitris Eleftheriotis (University of Glasgow, Murray Pratt (University of Technology Sydney and Ilaria Vanni, (University of Technology Sydney. As the editors’ opening essay emphasises, this issue is not concerned to perpetuate myths of a Europe united or federated, or even cohered by shared values. Rather, it aims to reclaim something of the conceptual, transcultural and locational uncertainties encoded in the foundation myth of Europe’s origins: Europa’s seduction and abduction by Zeus, disguised as a white bull. As the editors argue, this myth is marked by the physical elusiveness of Europe’s actual location (Homer’s Europa being, for example, Phoenician, in what is now Syria, and also complicated by centuries of amendments and revisions. Thus, by approaching contemporary Europe through the prism of a mutating and unanchored foundational fiction, the editors argue that that fiction ‘can be used to understand how in Europe particular local histories and local knowledge intersect with global issues, and conversely how what appears to be “European” is, in fact, the result of global encounters. Narratives of European values need to be located in this striated space, while friction as an organising metaphor also explains the slippage and relation between the lived, heterogeneous embodiments of contemporary Europe and abstract notions of values.’ The other essays gathered in this special issue endorse this notion of a striated Europe, a shifting space best regarded as a space of friction. I would like to thank all of the authors included in this special issue for their patience, and their support for the Contesting Euro Visions ideal that frames the issue. I would also like to take the opportunity to announce a call for papers for the July 2008 issue of PORTAL, entitled

  6. Connection between the Silk Road Pattern in July and the following January temperature over East Asia

    He, Shengping; Liu, Yang; Wang, Huijun

    2017-04-01

    This study investigates a cross-seasonal influence of the Silk Road Pattern (SRP) in July and discusses the related mechanism. Both the reanalysis and observational datasets indicate that the July SRP is closely related to the following January temperature over East Asia during 1958/59-2001/02. Linear regression results reveal that, following a higher-than-normal SRP index in July, the Siberian high, Aleutian low, Urals high, East Asian trough, and meridional shear of the East Asian jet intensify significantly in January. Such atmospheric circulation anomalies are favorable for northerly wind anomalies over East Asia, leading to more southward advection of cold air and causing a decrease in temperature. Further analysis indicates that the North Pacific sea surface temperature anomalies (SSTAs) might play a critical role in storing the anomalous signal of the July SRP. The significant SSTAs related to the July SRP weaken in October and November, re-emerge in December, and strengthen in the following January. Such an SSTA pattern in January can induce a surface anomalous cyclone over North Pacific and lead to dominant convergence anomalies over northwestern Pacific. Correspondingly, significant divergence anomalies appear, collocated in the upper-level troposphere in situ. Due to the advection of vorticity by divergent wind, which can be regarded as a wave source, a stationary Rossby wave originates from North Pacific and propagates eastward to East Asia, leading to temperature anomalies through its influence on the large-scale atmospheric circulation.

  7. L’archive comme enjeu de présentation de soi : la mémoire du syndicat des ouvriers des savonneries à Naplouse, Cisjordanie Archives as a Self-Presentation Issue: the Memory of the Soap Factory Workers’ Union in Nablus, West Bank

    Full Text Available Cet article part de la « quête d’archives » à laquelle je me suis livrée dans le cadre d’une enquête sur le syndicat des ouvriers des savonneries à Naplouse. Dans un premier temps, il interroge le caractère insaisissable de la mémoire de ce syndicat, qui a laissé peu de traces matérielles de son existence. Je me penche ensuite sur la manière dont les documents écrits étaient utilisés par deux anciens ouvriers des savonneries, dans la reconstruction de la mémoire syndicale. Je montre que ces ouvriers mobilisaient conjointement deux régimes de légitimation de leur parole qui, loin de s’opposer, devaient se renforcer mutuellement : la possession de « documents authentiques » ne devait pas tant ajouter foi au contenu de leur discours, que fournir de l’autorité à leur parole. L’article interroge, in fine, la puissance symbolique accordée à l’écrit, et plus largement la matérialité dans le régime de légitimation du discours, en particulier en situation d’entretien.This article is based on the “quest for archives” I pursued in the context of a study on the soap factory workers’ union in Nablus. It begins by considering the elusive character of this union, which left few material traces of its existence. Next I examine how written documents were used by two former soap factory workers to construct the memory of the union. I show that these workers used two parallel systems to legitimise their words—systems that, far from clashing, reinforced each other: the possession of “authentic documents” should not so much make the discourse they contain more believable, but rather lend authority to their words. The article ultimately considers the power of discourse, particularly in an interview context.

    Full Text Available Vers la fin de la Deuxième Guerre mondiale, le régime communiste dirigé par Staline a déporté de nombreuses populations non slaves de la péninsule de Crimée et du Caucase : Tatars, Grecs, Arméniens, Tchétchènes, etc. Le motif invoqué était la collaboration de certains éléments de ces ethnies avec l’occupant nazi durant la guerre. Parmi ceux-ci, les Tatars criméens, une population musulmane qui habitait la péninsule depuis des siècles, a souffert un nombre élevé de décès durant la déportation, notamment dans les colonies de travail de l’Ouzbékistan et de Sibérie. La dimension tragique de cet acte est impressionnante et les conséquences se reflètent aujourd’hui, après 60 ans, sur les survivants de l’ethnie tatare et leurs familles, tant au niveau de la conscience individuelle que de la conscience collective. Porteurs depuis des décennies d’une mémoire considérée par le régime soviétique comme « subversive », ayant le stigmate péjoratif de « traître », dépouillés de leurs biens et, encore plus important, de leur identité ethnique, les Tatars criméens ont beaucoup de difficultés à se réintégrer dans l’Ukraine actuelle, après leur retour dans leur patrie. Dans ce cas, la mémoire des survivants a un rôle à la fois pédagogique et de liant dans la démarche de reconstruction de leur identité brisée. Ce processus de reconstruction identitaire a lieu aujourd’hui dans un contexte conflictuel créé par les avatars de l’histoire et les fréquentes mutations de peuples, qui ont modifié la configuration ethnique de la péninsule de Crimée.

    An attempt has been made to simulate the unprecedented heavy precipitation of 94.4 cm in a day over Santacruz, Mumbai during 0300 UTC 26 July to 0300 UTC 27 July 2005. Three experiments have been conducted using Advanced Regional Prediction System model developed by Center for Analysis and Prediction of Storms of Oklahoma University, USA. In first experiment the model input at large domain size has been obtained using NCEP/NCAR reanalysis data at 2.5° × 2.5° lat. lon. resolution. In other two experiments model input at large as well as at small domain sizes, have been obtained from NCEP/NCAR FNL data of 1° × 1° lat. lon. resolution. In all three experiments model’s horizontal resolution is 40 km and integration period is 30 hours from 0000 UTC 26 July 2005. Based on the temporal distribution of observed rainfall rates it is considered that the rainfall of 38.1 cm during 0900 1200 UTC on 26 July could be due to cloud burst phenomenon and 56.3 cm from 1200 UTC of 26 July to 0300 UTC of 27 July has been due to continuous regeneration of thunderstorm activity under influence of mesoscale cloud complex. It is found that model forecast of rainfall in first experiment was qualitatively as well as quantitatively very poor. Among other two, experiment with large domain size has predicted better rainfall values and location compared to the experiment with small domain size. The larger domain has produced rainfall of 41 cm as against observed rain rate of 56.3 cm. during 1200 UTC of 26 July to 0300 UTC of 27 July. Divergence, vorticity, vertical velocity and moisture parameters are examined in relation with the various stages of the event. The maximum values of convergence, vorticity and moisture fluxes precede the initial phase of mature stage, however vertical velocity follows the later phase of mature stage. Vorticity budget over the location of maximum rainfall, revealed the significant role of tilting term in maintenance and dissipation of the cloud complex
