    The French-Speaking Cellular Haematology Group (GFHC) recently published criteria for microscopic analysis of a blood smears when a hemogram is requested. In order to evaluate and improve these recommendations using an XN (Sysmex) analyzer, we assessed 31,836 samples categorized into two sub-groups of patients either receiving or not receiving care in the clinical hematology/oncology departments of two university hospitals. By combining the manufacturer's recommendations and the GFHC recommendations, 21.3% of samples had a positive review flag in phase 1 of our study (17,991 samples). In phase 2 (13,845 samples), increasing the immature granulocytes (IG) percentage from 5-10% as a review trigger threshold, and ignoring slides with isolated flags 'PLT HIGH' (thrombocytosis) or 'MCV LOW' (microcytosis) or 'Blast/Abn Lymph and Atypical Lymph' (blast cells/abnormal lymphocytes and atypical lymphocytes) (in the absence of abnormal cells on a previous blood smear within 72 h), enabled us to significantly reduce the number of slides reviewed from 21.3-15.0% (p < 0.0001), without loss of clinical value. This decrease occurred in both sub-groups (hematology 48.7-38.0%, non-hematology 18.3-11.7%, p < 0.0001). In conclusion, the application of the GFHC criteria adapted to XN analyzers has enabled us to optimize the hematology laboratory processes, and thus reduce the production costs and the turnaround time of hemogram results.

    2016-08-01

    In this article the energy transfer between a flow and a fluttering piezoelectric plate is investigated. In particular, the benefits of the use of a synchronized switch harvesting on inductor (SSHI) circuit are studied. Both wind tunnel experiments and numerical simulations are conducted in order to analyze the influence of the switching process on the dynamics and the efficiency of the system. Numerical simulations consist of a weakly nonlinear model of a plate in axial flow equipped with a single pair of piezoelectric patches, discretized using a Galerkin method where basis functions are the modes of the plate in vacuum. The discretized model is then integrated in time. The results presented in this paper show that a significant improvement of the harvested energy can be obtained using SSHI circuits compared to basic resistive circuits. It is also shown that for strongly coupled systems, the switching process inherent to he SSHI circuit has a significant impact on the dynamics of the flag, which tends to decrease the relative efficiency gain.

  3. COOPER, HERON, AND HEWARD'S APPLIED BEHAVIOR ANALYSIS (2ND ED.): CHECKERED FLAG FOR STUDENTS AND PROFESSORS, YELLOW FLAG FOR THE FIELD

    Friman, Patrick C

    2010-01-01

    At last, the field of applied behavior analysis has a beautifully crafted, true textbook that can proudly stand cover to cover and spine to spine beside any of the expensive, imposing, and ornately designed textbooks used by college instructors who teach courses in conventional areas of education or psychology. In this review, I fully laud this development, credit Cooper, Heron, and Heward for making it happen, argue that it signifies a checkered flag for students and professors, and recommend the book for classes in applied behavior analysis everywhere. Subsequently, I review its chapters, each of which could easily stand alone as publications in their own right. Finally, I supply a cautionary note, a yellow flag to accompany the well-earned checkered flag, by pointing out that, as is true with all general textbooks on applied behavior analysis, a major portion of the references involves research on persons who occupy only a tail of the normal distribution. To attain the mainstream role Skinner envisioned and most (if not all) behavior analysts desire, the field will have to increase its focus on persons who reside under the dome of that distribution.

    We evaluated the clinical usefulness (leukocyte distribution classification, morphologic classification, and morphologic flags) of the following four hematology analyzers: CELL-DYN Sapphire (CD-Sapphire) (Abbott Diagnostics, Santa Clara, CA, USA), ADVIA 120 (Bayer Diagnostics, Tarrytown, NY, USA), Beckman Coulter LH 750 (Beckman Coulter, Miami, FL, USA), and Sysmex XE-2100 (TOA Medical Electronics Co., Kobe, Japan). Four hundred thirty samples from patients and 100 samples from healthy individuals were analyzed. For distributional classification, the sensitivity rates of CD-Sapphire, ADVIA 120, LH 750, and XE-2100 were 93.1, 95.9, 94.9, and 94.9%, respectively, and the efficiency rates were 80.7, 81.6, 84.1, and 84.2%, respectively. For morphologic classification, the sensitivity rates of CD-Sapphire, ADVIA 120, LH 750, and XE-2100 were 88.6, 93.2, 77.3, and 94.3%, respectively, and the efficiency rates were 80.9, 73.0, 79.5, and 74.2%, respectively. Comparing the findings in different morphologic flags, XE-2100 showed the highest sensitivity for Blasts flag (90.9%); CD-Sapphire showed the highest sensitivity for Immature granulocytes and/or Left-shift flag (85.5%); ADVIA 120 showed the highest sensitivity for Atypical lymphocytes flag (60.0%); and LH 750 showed the highest sensitivity for Nucleated RBC flag (75.0%). Our results demonstrate that the four analyzers are comparable in overall performance. PMID:19062362

    We tested the capacity of the Sysmex UF-1000i system to detect yeasts in urine by screening a total of 22 132 urine samples received for culture in our microbiology laboratory during 1 year. We also analyzed different dilutions of previously filtered urine inoculated with a strain of Candida albicans. With clinical samples, a single cut-off point of 50 yeast-like cells (YLCs)/μL detected candiduria ≥10 000 colony forming units (CFU)/mL and >100 000 CFU/mL with a sensitivity of 87.3%/95.4%, a specificity of 97%, a negative predictive value of 95.9%, and a positive predictive value of 9.3%/5.7%. With the simulated samples, a linear relationship was observed between the dilution factor and the number of cells detected by UF-1000i. This instrument appears to be able to reliably rule out candiduria of a magnitude of at least 10 000 CFU/mL and facilitate urine sample screening, thereby providing fast results. The Sysmex UF1000i system can be adapted for candiduria screening by the use of an appropriate YLCs/μL cut-off point that takes account of the prevalence of candiduria in the population.

    The new fully automated reticulocyte analyzer, Sysmex R-1000 (TOA Medical Electronics, Kobe, Japan), was evaluated for its routine use in the Hematological Laboratory at the University Hospital Basel, Switzerland. The operating characteristics, such as within-run precision, linearity, and carryover, fulfilled the manufacturer's specifications and are excellent. Correlation with the standard method, manual reticulocyte counting, is linear for normal and high values. For low reticulocyte counts the regression points show a deviation from their linearity. An absolute zero value is not obtained by the R-1000. The R-1000 measures total RNA content of each cell and expresses the value as low fluorescence ratio (LFR), medium fluorescence ratio (MFR), and high fluorescence ratio (HFR). The analysis of this ratio resolves the problem of zero reticulocytes: A fraction of less than 0.002 (0.2%) with an LFR of 100% represents aplasia; a shift of the intensity of fluorescence to HFR heralds regeneration. Results of samples stored at room temperature remain stable and within the range of the within-run precision for up to 12 hours, when stored at 5 degrees C for more than 48 hours. The authors conclude that the R-1000 is easy to operate, fulfills the criteria for accuracy and precision, and is highly suitable for daily routine use in a large central hematologic laboratory.

  7. Flag flapping in a channel

    2015-11-01

    We study the flapping of a flag in an inviscid channel flow. We focus especially on how quantities vary with channel spacing. As the channel walls move inwards towards the flag, heavier flags become more unstable, while light flags' stability is less affected. We use a vortex sheet model to compute large-amplitude flapping, and find that the flag undergoes a series of jumps to higher flapping modes as the channel walls are moved towards the flag. Meanwhile, the drag on the flag and the energy lost to the wake first rise as the walls become closer, then drop sharply as the flag moves to a higher flapping mode.

    2001-11-01

    The National Radio Astronomy Observatory (NRAO) hosted the runners and support personnel of the "Americans United Flag Across America" run as the transcontinental memorial and fundraising effort came through New Mexico. The flag run arrived at NRAO's Very Large Array (VLA) radio telescope west of Socorro, NM, early in the post-Midnight morning of Monday, November 5, and departed after sunrise that morning en route to the Arizona border. Drivers, runners and support personnel stayed overnight at the VLA. During the night, a "VLA Night Owl Run" kept the flag moving around the VLA area until the westward trek resumed after dawn. The run began Oct. 11, one month after the terrorist attacks on New York and Washington. Organized by employees of American and United Airlines to honor the flight crews lost in those attacks, to show support for U.S. troops and to raise funds to help the victims' families, the run will take an American flag from Boston Logan Airport to Los Angeles International Airport. The Boston-to-Los Angeles trip represents the intended journey of American Flight 11 and United Flight 175, both of which were crashed by terrorists into the World Trade Center. "Our observatory was proud to host this group and honored that they brought this flag through our facility," said Miller Goss, NRAO's director of VLA operations. The runners carried a flag that flew in a U.S. F-16 over Iraq in support of Operation Southern Watch on Oct. 2, and has visited Ground Zero in Manhattan. The flag is scheduled to arrive in Los Angeles on Veterans Day, Nov. 11. The National Radio Astronomy Observatory is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc.

    2015-01-01

    Background Sample stability is a crucial aspect for the quality of results of a haematology laboratory. This study was conducted to investigate the reliability of haematological testing using Sysmex XN in samples stored for up to 24 h at different temperatures. Materials and methods Haematological tests were performed on whole blood samples collected from 16 ostensibly healthy outpatients immediately after collection and 3 h, 6 h or 24 h afterwards, with triple aliquots kept at room temperature, 4 °C or 37 °C. Results No meaningful bias was observed after 3 h under different storage conditions, except for red blood cell distribution width (RDW) and platelet count (impedance technique, PLT-I) at 37 °C. After 6 h, meaningful bias was observed for mean corpuscular haemoglobin (MCH) and mean corpuscular volume (MCV) at room temperature, red blood cell (RBC) count, mean corpuscular haemoglobin concentration (MCHC), MCH, MCV and PLT-I at 4 °C, and RBC, RDW, MCHC, MCH and PLT-I at 37 °C. After 24 h, a meaningful bias was observed for MCHC, MCV, platelet count (fluorescent technique, PLT-F) and mean platelet volume (MPV) at room temperature, MCHC, MCV, PLT-I and MPV at 4 °C, and all parameters except RBC count and MPV at 37 °C. Discussion Great caution should be observed when analysing results of haematological tests conducted more than 3 h after sample collection. PMID:26057491

    We established age- and gender-specific reference ranges for the 36 routine complete blood cell (CBC) and 57 cell population data (CPD) items in the Sysmex XN-2000 (Sysmex, Japan). In total, 280 peripheral blood samples were obtained from an equal number of healthy adults. Values for 36 routine items and 57 CPD items were obtained for each sample, and the results were categorized into six subgroups (N>39 in each subgroup) according to patient age (20-40, 41-60, and >60 yr) and gender (male and female), and compared with respect to age and gender differences. The majority of data items (22 of 36 routine CBC items and 44 of 57 CPD items) exhibited significant differences (P≤0.05) in their results with respect to age or gender, and several red cell-, lymphocyte-, and platelet-related data tended to decrease in women or older adults. These results provide a basis for establishing age- and gender-specific reference ranges for routine and CPD items in Sysmex XN-2000. Furthermore, these reference ranges could be used to determine clinical significance for new items of Sysmex XN-2000 in further studies. PMID:26915613

  14. Infrared Blobs : Time-dependent Flags

    NASA Astrophysics Data System (ADS)

    McCullough, P. R.; Mack, J.; Dulude, M.; Hilbert, B.

    2014-10-01

    We describe the creation of time-dependent flags for pixels associated with "blobs" on the WFC3 IR detector. We detect the blobs on flat fields obtained by repeated observations of the night side of the Earth. We provide the most complete census of IR blobs' positions, radii, and times of first appearance. In aggregate, a set of 46 blobs, 27 "strong" and 19 "medium" in their effective scattering cross section, affect slightly less than 1% of the pixels of the detector. A second set of 81 "weak" (and typically smaller) blobs affect another 1% of the pixels. In the past, the "blob" flag, bit 9 (i.e. value = 512) in the data quality (DQ) array described in Table 2.5 of the WFC3 Data Handbook (Rajan et al. 2010) has been a static 2-D array; henceforth a set of such arrays, each associated with a "use after" date corresponding to the appearance of one or more new blobs, can be used. We prepared such DQ arrays using the 46 "strong" and "medium" blobs and discuss why we did not include the fainter blobs therein. As an added data product, we create and test a blob flat field that corrects the effects of blobs on extended emission; however, it should not be applied if stellar photometry is the goal.

  16. Synchronized flutter of two slender flags

    NASA Astrophysics Data System (ADS)

    Mougel, Jérôme; Doaré, Olivier; Michelin, Sébastien

    2016-08-01

    The interactions and synchronization of two parallel and slender flags in a uniform axial flow are studied in the present paper by generalizing Lighthill's Elongated Body Theory (EBT) and Lighthill's Large Amplitude Elongated Body Theory (LAEBT) to account for the hydrodynamic coupling between flags. The proposed method consists in two successive steps, namely the reconstruction of the flow created by a flapping flag within the LAEBT framework and the computation of the fluid force generated by this nonuniform flow on the second flag. In the limit of slender flags in close proximity, we show that the effect of the wakes have little influence on the long time coupled-dynamics and can be neglected in the modeling. This provides a simplified framework extending LAEBT to the coupled dynamics of two flags. Using this simplified model, both linear and large amplitude results are reported to explore the selection of the flapping regime as well as the dynamical properties of two side-by-side slender flags. Hydrodynamic coupling of the two flags is observed to destabilize the flags for most parameters, and to induce a long-term synchronization of the flags, either in-phase or out-of-phase.

  17. Stall flag, prior development and first results. Aiming at visualization of the stalled area on full scale wind turbines

    SciTech Connect

    Corten, G.P.

    1997-02-01

    Presently even the most sophisticated predictions of the stall behavior of commercial wind turbines are often bad. Therefore a new method to visualize stall was developed. The method is based on a very thin detector, the so called stall flag, that provides a clearly visible signal that shows whether the flow over the stall flag is reversed (stalled) or not. The stall flags operate passively, are contactless and have a fast response, they can be seen as advanced tufts. Their weight is about 1 g and they can be seen clearly from the ground. The stall flags do not limit the operational range of the turbine under study. To equip the turbine with stall flags takes only several hours, installation of a rotating camera is not required. Stall flags have the potential to visualize the complete stalled area on commercial rotors. ECN applied for a patent on the stall flag. This report starts with the arguments to develop the stall flags. Then the design of the stall flag and the optical details on the visualization method are presented. Also the first results of the application of stall flags on turbines in the fields will be described. Among these results are high quality photographs of the area of reversed/radial flow on a 10 m diameter wind turbine and several test pictures of the Rotorline 32 rotor of the Nedwind 30 wind turbine.

  20. Stability and scalability of piezoelectric flag

    NASA Astrophysics Data System (ADS)

    Wang, Xiaolin; Alben, Silas; Li, Chenyang; Young, Yin Lu

    2015-11-01

    Piezoelectric material (PZT) has drawn enormous attention in the past decades due to its ability to convert mechanical deformation energy into electrical potential energy, and vice versa, and has been applied to energy harvesting and vibration control. In this work, we consider the effect of PZT on the stability of a flexible flag using the inviscid vortex-sheet model. We find that the critical flutter speed is increased due to the extra damping effect of the PZT, and can also be altered by tuning the output inductance-resistance circuit. Optimal resistance and inductance are found to either maximize or minimize the flutter speed. The former application is useful for the vibration control while the latter is important for energy harvesting. We also discuss the scalability of above system to the actual application in air and water.

  6. Coupled-flutter of two slender flags

    NASA Astrophysics Data System (ADS)

    Jérôme, Mougel; Sébastien, Michelin; Olivier, Doaré

    2015-11-01

    A flag in axial flow is subject to flutter instability that leads to large-amplitude flapping of the structure. When two flags are placed parallel to each other, they interact hydrodynamically leading to coupled dynamics of the system. The understanding of the possible dynamical regimes is crucial in the recent context of energy harvesting using piezoelectric fags. In this study, we consider coupled-flutter of two slender flags. Based on an extension of the famous model by Lighthill commonly called Large Amplitude Elongated Body Theory to the two-flags case, both linear and large-amplitude dynamics of such a coupled system will be presented.

  9. GLSMs for partial flag manifolds

    NASA Astrophysics Data System (ADS)

    Donagi, Ron; Sharpe, Eric

    2008-12-01

    In this paper we outline some aspects of nonabelian gauged linear sigma models. First, we review how partial flag manifolds (generalizing Grassmannians) are described physically by nonabelian gauged linear sigma models, paying attention to realizations of tangent bundles and other aspects pertinent to (0, 2) models. Second, we review constructions of Calabi-Yau complete intersections within such flag manifolds, and properties of the gauged linear sigma models. We discuss a number of examples of nonabelian GLSMs in which the Kähler phases are not birational, and in which at least one phase is realized in some fashion other than as a complete intersection, extending previous work of Hori-Tong. We also review an example of an abelian GLSM exhibiting the same phenomenon. We tentatively identify the mathematical relationship between such non-birational phases, as examples of Kuznetsov's homological projective duality. Finally, we discuss linear sigma model moduli spaces in these gauged linear sigma models. We argue that the moduli spaces being realized physically by these GLSMs are precisely Quot and hyperquot schemes, as one would expect mathematically.

  2. Electro-hydrodynamic synchronization of piezoelectric flags

    NASA Astrophysics Data System (ADS)

    Xia, Yifan; Doaré, Olivier; Michelin, Sébastien

    2016-08-01

    Hydrodynamic coupling of flexible flags in axial flows may profoundly influence their flapping dynamics, in particular driving their synchronization. This work investigates the effect of such coupling on the harvesting efficiency of coupled piezoelectric flags, that convert their periodic deformation into an electrical current. Considering two flags connected to a single output circuit, we investigate using numerical simulations the relative importance of hydrodynamic coupling to electrodynamic coupling of the flags through the output circuit due to the inverse piezoelectric effect. It is shown that electrodynamic coupling is dominant beyond a critical distance, and induces a synchronization of the flags' motion resulting in enhanced energy harvesting performance. We further show that this electrodynamic coupling can be strengthened using resonant harvesting circuits.

  3. Validation of JASON and Envisat Rain flags

    2003-04-01

    A new rain flag based on the differential attenuation between the two operating frequency of the JASON (Ku/C band) and Envisat RA2 (Ku/S band) altimeters has been defined and is operationaly used. These rain flags use the departure from a normal (or rain free) KU/C or Ku/S backscatter data relation to detect the presence of rain within the altimeter footprint. For both altimeters, the validation of the rain flag required first the validation of the dual frequency sigmanaugh relation and then a validation of the rain flagging process. We present the validation of the two rain flags. For Jason the results are then compared to the coincident Topex data. We also present a first estimate of the rain climatology estimated from each altimeter (Topex, Jason, Envisat) and by combining the 2 or 3 sensors.

  4. Image Artifact Flagging in the Kepler Pipeline

    NASA Astrophysics Data System (ADS)

    Clarke, Bruce; Caldwell, Douglas; Kolodziejczak, Jeffery

    2015-08-01

    Systematic instrument noise in the raw Kepler pixel data includes time-varying crosstalk from the fine guidance sensor (FGS) clock signals, manifestations of drifting moiré pattern as locally correlated nonstationary noise and rolling band artifacts (RBA). The Kepler pipeline module Dynablack produces best fit black level estimates per pixel per cadence by modeling a combination of collateral, FFI, reverse clocked and ARP target data. A search for transit features in the fit residuals identifies spatial regions and time intervals of strong time-varying black level which we identify as RBA. Dynablack produces flags marking these these RBA regions on a per row per cadence basis for several different transit time scales. The Photometric Analysis module (PA) generates per target per cadence data quality flags based on the Dynablack RBA flags which are in turn used by the Data Validation pipeline module (DV) in producing a contamination report associated with each target processed. The Dynablack (per row) RBA flags as well as a proxy for the per target flags produced in PA will be included in the final Kepler data release scheduled to arrive at the MAST in 2016.We detail how the RBA flags are produced in Dynablack, how these are then used to produce the per target quality flags used in DV and discuss why they should be considered when searching for transit signatures in the archived Kepler light curves. Funding for the Kepler Mission has been provided by the NASA Science Mission Directorate.

  16. Dynamics of Flapping Flag in Axial Flow

    NASA Astrophysics Data System (ADS)

    Abderrahmane, Hamid Ait; Fayed, Mohamed; Gunter, Amy-Lee; Paidoussis, Michael P.; Ng, Hoi Dick

    2010-11-01

    We investigate experimentally the phenomenon of the flapping of a flag, placed within a low turbulent axial flow inside a small scale wind tunnel test section. Flags of different sizes and flexural rigidities were used. Image processing technique was used and the time series of a given point on the edge of the flag was analyzed. The stability condition of the flag was obtained and compared to the recent theoretical models and numerical simulations. Afterwards, the nonlinear dynamics of the flapping was investigated using nonlinear time series method. The nonlinear dynamics is depicted in phase space and the correlation dimension of the attractors is determined. On the basis of observations made in this study, some conclusions on the existing models were drawn.

  17. The Forced Motion of a Flag

    NASA Astrophysics Data System (ADS)

    Howe, Michael; Manela, Avshalom

    2008-11-01

    The prevailing view of the dynamics of flapping flags is that the onset of motion is caused by linear instability of the initial planar state. This view is reexamined by considering the forced motion of a flag immersed in a high-Reynolds number flow and subject to vortex shedding from its cylindrical pole. Vortex shedding is represented by a ``street'' of discrete line vortices released periodically from the pole and convected in the mean wind over the surfaces of the flag. It is found that forced motion is possible when the flag is still temporally stable, which suggests that the present mechanism should be taken into account in future high-Reynolds experimental investigations.

  18. Flag flutter in inviscid channel flow

    NASA Astrophysics Data System (ADS)

    Alben, Silas

    2015-03-01

    Using nonlinear vortex-sheet simulations, we determine the region in parameter space in which a straight flag in a channel-bounded inviscid flow is unstable to flapping motions. We find that for heavier flags, greater confinement increases the size of the region of instability. For lighter flags, confinement has little influence. We then compute the stability boundaries analytically for an infinite flag and find similar results. For the finite flag, we also consider the effect of channel walls on the large-amplitude periodic flapping dynamics. We find that multiple flapping states are possible but rare at a given set of parameters, when periodic flapping occurs. As the channel walls approach the flag, its flapping amplitude decreases roughly in proportion to the near-wall distance, for both symmetric and asymmetric channels. Meanwhile, its dominant flapping frequency and mean number of deflection extrema (or "wavenumber") increase in a nearly stepwise fashion. That is, they remain nearly unchanged over a wide range of channel spacing, but when the channel spacing is decreased below a certain value, they undergo sharp increases corresponding to a higher flapping mode.

  19. Immature platelet fraction measured on the Sysmex XN hemocytometer predicts thrombopoietic recovery after autologous stem cell transplantation

    Objectives A period of thrombocytopenia is common after stem cell transplantation (SCT). To prevent serious bleeding complications, prophylactic platelet transfusions are administered. Previous studies have shown that a rise in immature platelets precedes recovery of platelet count. Our aim was to define a cutoff value for immature platelets predicting thrombopoietic recovery within 2 d. Methods Hematological parameters were measured on the Sysmex XN hemocytometer. We calculated reference change values (RCV) for platelets in eight healthy individuals as marker for platelet recovery. To define a cutoff value, we performed ROC analysis using data from 16 autologous SCT patients. Results RCV for platelet concentration was 14.1%. Platelet recovery was observed 13 (median; range 9–31) days after SCT. Increase in immature platelet fraction (IPF) before platelet recovery was seen in all autologous SCT patients. Optimal cutoff IPF was found to be 5.3% for platelet recovery within 2 d (specificity 0.98, sensitivity 0.47, positive predictive value 0.93). Conclusions We identified an optimal cutoff value for IPF 5.3% to predict platelet recovery after autologous SCT within 2 d. Implementing this cutoff value in transfusion strategy may reduce the number of prophylactic platelet transfusions. PMID:24660761

    The flapping of the flag is a classical model problem for the understanding of fluid-structure interaction: How does the flat state lose stability? Why do the nonlinear effects induce hysteretic behavior? We show in this Letter that, in contrast with the commonly studied model, the full three-dimensional flag with gravity has no stationary state whose stability can be formally studied: The waves are oblique and must immediately be of large amplitude. The remarkable structure of these waves results from the interplay of weight, geometry, and aerodynamic forces. This pattern is a key element in the force balance which allows the flag to hold and fly in the wind: Large amplitude oblique waves are responsible for lift. PMID:22181612

    In the occasion of the celebrations for the 150th anniversary of the founding of Italy (1861-2011), it was decided to analyse the artwork "The Italian Flag" (La Bandiera Italiana) created by the artist Fernando Melani (Pistoia, 1907-1985), one of the precursors of the Poor Art artistic movement in Italy. This project is a follow-up to a previous study which was mainly focused on the pigments and dyes found in his home-studio. The main goal of this paper is to identify a correct diagnostic plan, based on the use of a combination of non-invasive and micro-invasive methodologies, in order to determine the state of preservation and define the best conservation procedures for a contemporary artwork. Visible, infrared and infrared false colour images as well as the Fibre Optic Reflectance Spectroscopy (FORS) technique were applied in situ to analyse The Italian Flag. Laser Induced Breakdown Spectroscopy (LIBS), Fourier Transform Infrared (FT-IR) and micro-Raman spectroscopies, Pyrolysis-Gas Chromatography/Mass Spectroscopy (Py-GC/MS), High Performance Liquid Chromatography with Diode Arrays Detection (HPLC-DAD) and Mass Spectrometric Detection (HPLC-ESI-Q-ToF) were all applied to three small samples detached from the three painted (green-blue, white and red-yellow, respectively) areas of the flag. The combination of the data obtained with all these techniques made possible a comprehensive understanding of both the chemical composition and physical behaviour of the materials used by the artist and supported curators in defining the preventive conservation of this artwork.

  4. Stability and scalability of piezoelectric flags

    NASA Astrophysics Data System (ADS)

    2016-02-01

    We investigate the effect of piezoelectric material on the flutter speed, vibration mode and frequency, and energy harvesting power and efficiency of a flexible flag in various fluids. We develop a fully coupled fluid-solid-electric model by combining the inviscid vortex sheet model with a linear electro-mechanical coupling model. A resistance only circuit and a resonant resistance-inductance (RL) circuit are considered. For a purely resistive circuit, an increased electro-mechanical coupling factor results in an increased flutter speed, vibration frequency, averaged electric power, and efficiency. A consistent optimal resistance is found that maximizes the flutter speed and the energy harvesting power. For a resonant RL circuit, by tuning the inductance to match the circuit frequency to the flag's vibration frequency, the flutter speed can be greatly decreased, and a larger averaged power and efficiency are obtained. We also consider a model scale setup with several commonly used commercial materials for operating in air and water. Typical ranges of dimensionless parameters are obtained for four types of material that span a wide range of solid density and rigidity values. We find that the resistance only circuit is more effective when the flag is placed in a lighter fluid (e.g., air), while the RL circuit is able to reduce the flutter speed when the flag is placed in a heavier fluid (e.g., water).

  12. Interaction of Two Flapping Flags in Axial Flow

    NASA Astrophysics Data System (ADS)

    Gunter, Amy-Lee; Fayed, Mohamed; Abderrahmane, Hamid Ait; Paidoussis, Michael P.; Ng, Hoi Dick

    2010-11-01

    The flapping of two parallel flags in axial low turbulence flow is investigated experimentally inside a small scale wind tunnel test section. The variables of the problem are the size and flexural rigidity of the flags, and the distance that separates the two flags. The flow velocity represents the control parameter that governs the coupling and flapping mode of the flags. Two flapping modes, in-phase and out-of-phase modes, were observed in the experiment. Image processing technique was used and the time series of a given point on the flag edge was analyzed. The stability condition of the flags was obtained and compared to the recent theoretical models. The dynamics of the coupling between the two flags is also studied.

  13. Ejecta modeling in the FLAG hydrocode

    NASA Astrophysics Data System (ADS)

    Fung, Jimmy; Harrison, Alan

    2011-11-01

    We present the development of an ejecta model in the FLAG code. Ejecta is the term given to particulate matter produced at the free surface of a material subject to extreme shock loading. Modeling ejecta in a continuum hydrodynamics code challenges assumptions underlying the numerical approximations made in the hydrodynamics; the representative scales for the particulates are much smaller than the scales for the bulk material producing the ejecta. The FLAG hydrocode models continuum mechanics in an Arbitrary-Eulerian-Lagrangian framework. To model ejecta in FLAG, a hybrid particle-mesh representation was defined that allows for coupling with continuum materials. Numerical models were developed and implemented for particle production and integrating the particle equations of motion, while conserving mass, momentum and energy. This work documents advances in source and transport modeling, calibration and validation. Spatial and temporal dependencies have been added to the source models to account for free-surface geometry, mesh dependence, and shock loading. Physically relevant drag models have been implemented. These will be presented along with calibration results.

  14. Interaction between two side-by-side inverted flags

    NASA Astrophysics Data System (ADS)

    Huertas-Cerdeira, Cecilia; Fan, Boyu; Barizien, Antoine; Gharib, Morteza

    2015-11-01

    The inverted flag instability occurs when an elastic plate that is free at its leading edge and clamped at its trailing edge is subjected to an axial wind. The oscillating motion that follows has received recent attention. However, previous studies have focused on the dynamics of a single flag even though these are rarely found isolated in natural phenomena, such as the fluttering of leaves in the wind. The interaction between two side-by-side inverted flags has been investigated, analyzing the effects of the distance between flags and the wind speed. Both in-phase and anti-phase coupling have been observed for different ranges of these parameters.

    Saxena, Payal; Canto, Marcia Irene

    2013-07-01

    The key to detection and treatment of early neoplasia in Barrett's esophagus (BE) is thorough and careful inspection of the Barrett's segment. The greatest role for red flag techniques is to help identify neoplastic lesions for targeted biopsy and therapy. High-definition white light endoscopy (HD-WLE) can potentially improve endoscopic imaging of BE compared with standard endoscopy, but little scientific evidence supports this. The addition of autofluorescence imaging to HD-WLE and narrow band imaging increases sensitivity and the false-positive rate without significantly improving overall detection of BE-related neoplasia.

  1. Where no flag has gone before: Political and technical aspects of placing a flag on the Moon

    NASA Technical Reports Server (NTRS)

    Platoff, Anne M.

    1993-01-01

    The flag on the Moon represents an important event in vexillological history. The political and technical aspects of placing a flag on the Moon, focusing on the first Moon landing, is examined. During their historic extravehicular activity, the Apollo 11 crew planted the flag of the United States on the lunar surface. This flag-raising was strictly a symbolic activity, as the United Nations Treaty on Outer Space precluded any territorial claim. Nevertheless, there were domestic and international debates over the appropriateness of the event. Congress amended the agency's appropriations bill to prevent the National Aeronautics and Space Administration (NASA) from placing flags of other nations, or those of international associations, on the Moon during missions funded solely by the United States. Like any activity in space exploration, the Apollo flag-raising also provided NASA engineers with an interesting technical challenge. They designed a flagpole with a horizontal bar allowing the flag to 'fly' without the benefit of wind to overcome the effects of the Moon's lack of an atmosphere. Other factors considered in the design were weight, heat resistance, and ease of assembly by astronauts whose space suits restricted their range of movement and ability to grasp items. As NASA plans a return to the Moon and an expedition to Mars, we will likely see flags continue to go 'where no flag has gone before'.

  8. Effects of morphology on the flapping dynamics of inverted flags

    NASA Astrophysics Data System (ADS)

    The behavior of inverted flags has received recent attention in the study of the interaction of flexible bodies with fluid flows. It has implications in a variety of natural phenomena, such as the fluttering of leaves in the wind. As opposed to a conventional flag, defined by a fixed leading edge and a free trailing edge, an inverted flag has a free leading edge and a fixed trailing edge. The reversed flow orientation of inverted flags has led to a surprising observation. Over a narrow range of wind speeds, they exhibit a large-amplitude flapping motion that is not present in their conventional counterparts. Our study experimentally investigates the effects of flag morphology on the flapping behavior of inverted flags. Different flags ranging from rectangles to triangles are studied in a wind tunnel to assess the underlying parameters that govern their dynamics. We observe a significant shift in the limit-cycle flapping mode that is a function of flag shape parameters. This research is supported by the Lester Lees Aeronautics Summer Undergraduate Research Fellowship and the Gordon and Betty Moore Foundation.

  11. Ontologies for ship's flag search on the Web

    NASA Astrophysics Data System (ADS)

    Gkinos, Nikolaos-Panagiotis; Triakosaris, Evangelos; Galiotou, Eleni

    2015-02-01

    In this paper, we discuss issues on the representation and search of maritime data on the semantic web. In particular, we are concerned with data related to the requirements put forward by ship registries and should be met in view of a ship's flag acquisition. The choice of a ship's flag is a matter of crucial importance since it is the basis of tax payment and rule and regulation enforcement for the flying of flags. In our approach, flags and corresponding requirements are represented in the form of a ontology. Data "opening" and linking with the use of the ontology in question, will facilitate a ship's flag search based on its particular characteristics and will provide useful information on ship registration requirements.

  12. Structure of anti-FLAG M2 Fab domain and its use in the stabilization of engineered membrane proteins

    SciTech Connect

    Roosild, Tarmo P.; Castronovo, Samantha; Choe, Senyon

    2006-09-01

    The X-ray crystallographic analysis of anti-FLAG M2 Fab is reported and the implications of the structure on FLAG epitope binding are described as a first step in the development of a tool for the structural and biophysical study of membrane proteins. The inherent difficulties of stabilizing detergent-solubilized integral membrane proteins for biophysical or structural analysis demand the development of new methodologies to improve success rates. One proven strategy is the use of antibody fragments to increase the ‘soluble’ portion of any membrane protein, but this approach is limited by the difficulties and expense associated with producing monoclonal antibodies to an appropriate exposed epitope on the target protein. Here, the stabilization of a detergent-solubilized K{sup +} channel protein, KvPae, by engineering a FLAG-binding epitope into a known loop region of the protein and creating a complex with Fab fragments from commercially available anti-FLAG M2 monoclonal antibodies is reported. Although well diffracting crystals of the complex have not yet been obtained, during the course of crystallization trials the structure of the anti-FLAG M2 Fab domain was solved to 1.86 Å resolution. This structure, which should aid future structure-determination efforts using this approach by facilitating molecular-replacement phasing, reveals that the binding pocket appears to be specific only for the first four amino acids of the traditional FLAG epitope, namely DYKD. Thus, the use of antibody fragments for improving the stability of target proteins can be rapidly applied to the study of membrane-protein structure by placing the short DKYD motif within a predicted peripheral loop of that protein and utilizing commercially available anti-FLAG M2 antibody fragments.

  13. Soap Films Burst Like Flapping Flags

    NASA Astrophysics Data System (ADS)

    Lhuissier, Henri; Villermaux, Emmanuel

    2009-07-01

    When punctured, a flat soap film bursts by opening a hole driven by liquid surface tension. The hole rim does not, however, remain smooth but soon develops indentations at the tip of which ligaments form, ultimately breaking and leaving the initially connex film into a mist of disjointed drops. We report on original observations showing that these indentations result from a flaglike instability between the film and the surrounding atmosphere inducing an oscillatory motion out of its plane. Just like a flag edge flaps in the wind, the film is successively accelerated on both sides perpendicularly to its plane, inducing film thickness modulations and centrifuging liquid ligaments that finally pinch off to form the observed spray. This effect exemplifies how the dynamics of fragile objects such as thin liquid films is sensitive to their embedding medium.

  14. Self-propulsion of a heaving and pitching flexible flag

    NASA Astrophysics Data System (ADS)

    Kim, Boyoung; Park, Sung Goon; Sung, Hyung Jin

    2015-11-01

    Flapping motions of flexible flags are widespread in nature. Birds, fish, and insects use their wings, fins, or bodies to stay afloat and to advance forward in the surrounding fluids. In the present study, a self-propelled flexible flag with heaving and pitching motions in a quiescent flow has been simulated by using the immersed boundary method. The flexible flag can move freely in the horizontal direction and the body of the flexible flag moves passively along the head. The motion of the head of the flag was described as a harmonic heaving oscillation in the vertical direction. The motion of the angle of the head was described as a harmonic oscillation with a moving clamped condition for the heaving and pitching flag. The cruising speed and the swimming efficiency of the self-propelled flag were determined as functions of the bending coefficient (γ) , the heaving amplitude (Ah) , the pitching amplitude (Ap) , the heaving frequency (St), and the phase difference (Δϕ) between Ah and Ap. We conducted a parametric study on the optimized the cruising speed and the swimming efficiency with respect to γ, St, Ah, Ap, and Δϕ

    Painters are suspended on platforms from the top of the 525-foot- high Vehicle Assembly Building (VAB) at KSC during repainting of the American flag. The flag spans an area 209 feet by 110 feet and will require 510 gallons of red, white and blue paint. Each stripe of the flag is 9 feet wide and each star is 6 feet in diameter. The platforms are operated by two electric motors and travel 35 feet per minute. Work is being done with rollers, with brushes being used for details. The paint was donated by ICI Devoe of Louisville, Ky. In addition to the flag, the Bicentennial Emblem on the other side of the VAB doors is being replaced by the NASA logo, honoring NASA's 40th anniversary (in October). The logo covers an area 110 feet by 132 feet. Work is expected to be completed in mid-September.

  9. On the wake dynamics of flapping inverted flags

    NASA Astrophysics Data System (ADS)

    Gilmanov, Anvar; Sotiropoulos, Fotis; Cosse, Julia; Gharib, Mory

    2014-11-01

    As recently shown experimentally by Kim et al. (JFM, 2013), when a flexible flag with a fixed trailing edge (an inverted flag) is exposed to a uniform inflow it can exhibit complex structural response and rich fluid-structure interaction (FSI) dynamics. We employ a new FSI numerical method to carry out large-eddy simulation (LES) of inverted flags in the range where large-amplitude flapping instabilities have been found experimentally. The numerical method integrates the curvilinear immersed boundary (CURVIB) FSI method of Borazjani et al. (JCP, 2008) with the thin-shell, rotation-free, finite-element (FE) formulation of Stolarski et al. (Int. JNME, 2013) and is able to simulate FSI of flexible thin bodies undergoing oscillations of arbitrarily large amplitude. The dynamic Smagorinsky model is employed for subgrid scale closure and a wall model is employed for reconstructing velocity boundary conditions. Comparisons with the experimental data show that the simulations are able to capture the structural response of the flag with very good accuracy. The computed results are analyzed to elucidate the structure and dynamics of the massively separated, unsteady flow shed off the flag edges. This work is supported by the US Department of Energy and the Minnesota Supercomputing Institute.

  10. Flutter analysis of a flag of fractional viscoelastic material

    NASA Astrophysics Data System (ADS)

    Chen, Ming; Jia, Lai-Bing; Chen, Xiao-Peng; Yin, Xie-Zhen

    2014-12-01

    We develop a two-dimensional model to study the effects of the material viscoelasticity on the dynamics of a flag in flow. Two periodic states of an elastic flag are firstly identified with different dimensionless bending stiffness: a lower frequency state and a higher frequency state. The Scott-Blair model and the fractional Kelvin-Voigt model are further used to represent the viscoelasticity of the flag material. When the Scott-Blair model is used, with the increase of the fractional derivative order α, the flag flapping frequency of the higher frequency state decreases abruptly, and that of the lower frequency state also shows a downward trend. When the system parameters are in a certain range, an interesting phenomenon is observed, where the time needed to achieve the periodic steady state initially increases and then decreases with increasing α. The phenomenon implies that the flag has a higher energy harvesting speed when α approaches 1. When the fractional Kelvin-Voigt model is used, the increasing α also causes the transition from the higher frequency state to the lower frequency state, and quasi-periodic states are observed during the transition. The fractional Kelvin-Voigt type viscoelasticity produces complex effects on the lower frequency state.

  11. Fluid-flow-induced flutter of a flag

    PubMed Central

    Argentina, Médéric; Mahadevan, L.

    2005-01-01

    We give an explanation for the onset of fluid-flow-induced flutter in a flag. Our theory accounts for the various physical mechanisms at work: the finite length and the small but finite bending stiffness of the flag, the unsteadiness of the flow, the added mass effect, and vortex shedding from the trailing edge. Our analysis allows us to predict a critical speed for the onset of flapping as well as the frequency of flapping. We find that in a particular limit corresponding to a low-density fluid flowing over a soft high-density flag, the flapping instability is akin to a resonance between the mode of oscillation of a rigid pivoted airfoil in a flow and a hinged-free elastic plate vibrating in its lowest mode.
