  1. The Sinuous Target

    Energy Technology Data Exchange (ETDEWEB)

    Zwaska, R. [Fermilab

    2015-06-01

    We report on the concept for a target material comprised of a multitude of interlaced wires of small dimension. This target material concept is primarily directed at high-power neutrino targets where the thermal shock is large due to small beam sizes and short durations; it also has applications to other high-power targets, particularly where the energy deposition is great or a high surface area is preferred. This approach ameliorates the problem of thermal shock by engineering a material with high strength on the micro-scale, but a very low modulus of elasticity on the meso-scale. The low modulus of elasticity is achieved by constructing the material of spring-like wire segments much smaller than the beam dimension. The intrinsic bends of the wires will allow them to absorb the strain of thermal shock with minimal stress. Furthermore, the interlaced nature of the wires provides containment of any segment that might become loose. We will discuss the progress on studies of analogue materials and fabrication techniques for sinuous target materials.

    1985-01-01

    The development of the on-line nuclear orientation (OLNO) technique is reviewed. The present potential of the technique is discussed in the light of the attainable temperatures, the use of ion implantation and the required isotope flux. Limitations associated with spin-lattice relaxation are considered in some detail and a survey of accessible nuclei is presented. An outline comparison is given between OLNO and other methods for producing orientation of nuclei, for measuring nuclear spins and static moments and for the study of level structure and transition probabilities. The conclusion is drawn that the method in its present form has extensive potential over a wide range of nuclei. Future prospects for in-beam polarisation giving access to nuclei of shorter half lives are referred to briefly. (Auth.)

    Using in situ high-speed imaging, we unveil details of a highly unsteady plastic flow mode in the cutting of annealed and highly strain-hardening metals. This mesoscopic flow mode, termed sinuous flow, is characterized by repeated material folding, large rotation, and energy dissipation. Sinuous flow effects a very large shape transformation, with local strains of ten or more, and results in a characteristic mushroomlike surface morphology that is quite distinct from the well-known morphologies of metal-cutting chips. Importantly, the attributes of this unsteady flow are also fundamentally different from other well-established unsteady plastic flows in large-strain deformation, like adiabatic shear bands. The nucleation and development of sinuous flow, its dependence on material properties, and its manifestation across material systems are demonstrated. Plastic buckling and grain-scale heterogeneity are found to play key roles in triggering this flow at surfaces. Implications for modeling and understanding flow stability in large-strain plastic deformation, surface quality, and preparation of near-strain-free surfaces by cutting are discussed. The results point to the inadequacy of the widely used shear-zone models, even for ductile metals.

  6. Refactoring Delta-Oriented Product Lines to achieve Monotonicity

    2016-03-01

    Full Text Available Delta-oriented programming (DOP is a flexible transformational approach to implement software product lines. In delta-oriented product lines, variants are generated by applying operations contained in delta modules to a (possibly empty base program. These operations can add, remove or modify named elements in a program (e.g., classes, methods and fields in a Java program. This paper presents algorithms for refactoring a delta-oriented product line into monotonic form, i.e., either to contain add and modify operations only (monotonic increasing or to contain remove and modify operations only (monotonic decreasing. Because of their simpler structure, monotonic delta-oriented product lines are easier to analyze. The algorithms are formalized by means of a core calculus for DOP of product lines of Java programs and their correctness and complexity are given.

  7. Aspect-Oriented Model-Driven Software Product Line Engineering

    Science.gov (United States)

    Groher, Iris; Voelter, Markus

    Software product line engineering aims to reduce development time, effort, cost, and complexity by taking advantage of the commonality within a portfolio of similar products. The effectiveness of a software product line approach directly depends on how well feature variability within the portfolio is implemented and managed throughout the development lifecycle, from early analysis through maintenance and evolution. This article presents an approach that facilitates variability implementation, management, and tracing by integrating model-driven and aspect-oriented software development. Features are separated in models and composed of aspect-oriented composition techniques on model level. Model transformations support the transition from problem to solution space models. Aspect-oriented techniques enable the explicit expression and modularization of variability on model, template, and code level. The presented concepts are illustrated with a case study of a home automation system.

  8. A novel mixing mechanism in sinuous seafloor channels: Implications for submarine channel evolution

    Dorrell, R. M.; Peakall, J.; Burns, C.; Keevil, G. M.

    2018-02-01

    Previous experimental studies of density currents in sinuous seafloor channels have almost exclusively studied hydrodynamics either by considering time independent, instantaneous, flow measurements or by compiling time-averaged flow measurements. Here we present a novel study of the time dependent dynamics of a density driven flow in a sinuous channel fed by a source of constant discharge. The experiments show that whilst source conditions may be temporally steady, flow conditions are temporally unsteady with timescales of flow variation driven by flow interaction with channel topography. Temporal variations reveal that both downstream and cross-stream flows vary significantly from time average observations and predictions, across scales larger than those predicted for turbulence in equivalent straight channels. Large-scale variations are shown to increase the average production of turbulence across the height of the flow, providing a new mechanism for enhanced mixing of sediment within gravity currents. Further such large-scale variations in flow conditions are recorded in the change in orientation of near-bed secondary flow, providing a plausible mechanism to reduce the cross-stream transport of bedload material and explain the ultimate stabilisation of sinuous seafloor channel systems.

  9. Verification of Software Product Lines with Delta-Oriented Slicing

    Science.gov (United States)

    Bruns, Daniel; Klebanov, Vladimir; Schaefer, Ina

    Software product line (SPL) engineering is a well-known approach to develop industry-size adaptable software systems. SPL are often used in domains where high-quality software is desirable; the overwhelming product diversity, however, remains a challenge for assuring correctness. In this paper, we present delta-oriented slicing, an approach to reduce the deductive verification effort across an SPL where individual products are Java programs and their relations are described by deltas. On the specification side, we extend the delta language to deal with formal specifications. On the verification side, we combine proof slicing and similarity-guided proof reuse to ease the verification process.

    2018-03-01

    We present the design, fabrication, and measured performance of a hierarchical sinuous-antenna phased array coupled to superconducting transition-edge-sensor (TES) bolometers for millimeter wavelengths. The architecture allows for dual-polarization wideband sensitivity with a beam width that is approximately frequency-independent. We report on measurements of a prototype device, which uses three levels of triangular phased arrays to synthesize beams that are approximately constant in width across three frequency bands covering a 3:1 bandwidth. The array element is a lens-coupled sinuous antenna. The device consists of an array of hemispherical lenses coupled to a lithographed wafer, which integrates TESs, planar sinuous antennas, and microwave circuitry including band-defining filters. The approximately frequency-independent beam widths improve coupling to telescope optics and keep the sensitivity of an experiment close to optimal across a broad frequency range. The design can be straightforwardly modified for use with non-TES lithographed cryogenic detectors such as kinetic inductance detectors. Additionally, we report on the design and measurements of a broadband 180° hybrid that can simplify the design of future multichroic focal planes including but not limited to hierarchical phased arrays.

  13. Spatial warping by oriented line detectors can counteract neural delays

    2013-01-01

    The slow speed of neural transmission necessitates that cortical visual information from dynamic scenes will lag reality. The “perceiving the present” (PTP) hypothesis suggests that the visual system can mitigate the effect of such delays by spatially warping scenes to look as they will in ~100 ms from now (Changizi, 2001). We here show that the Hering illusion, in which straight lines appear bowed, can be induced by a background of optic flow, consistent with the PTP hypothesis. However, importantly, the bowing direction is the same whether the flow is inward or outward. This suggests that if the warping is meant to counteract latencies, it is accomplished by a simple strategy that is insensitive to motion direction, and that works only under typical (forward-moving) circumstances. We also find that the illusion strengthens with longer pulses of optic flow, demonstrating motion integration over ~80 ms. The illusion is identical whether optic flow precedes or follows the flashing of bars, exposing the spatial warping to be equally postdictive and predictive, i.e., peri-dictive. Additionally, the illusion is diminished by cues which suggest the bars are independent of the background movement. Collectively, our findings are consistent with a role for networks of visual orientation-tuned neurons (e.g., simple cells in primary visual cortex) in spatial warping. We conclude that under the common condition of forward ego-motion, spatial warping counteracts the disadvantage of neural latencies. It is not possible to prove that this is the purpose of spatial warping, but our findings at minimum place constraints on the PTP hypothesis, demonstrating that any spatial warping for the purpose of counteracting neural delays is not a precise, on-the-fly computation, but instead a heuristic achieved by a simple mechanism that succeeds under normal circumstances.

  15. Eskers in Ireland, analogs for sinuous ridges on Mars

    2014-05-01

    Sinuous ridges on the surface of Mars are often inferred as putative esker ridges. Eskers cover several hundred kilometers of the Irish landscape and are one of the dominant landforms in the Irish Midlands. Well exposed stratigraphic sections and the body of existing knowledge due to extensive research carried out on these landforms make the Irish eskers an excellent analog for sinuous ridges on Mars. The Irish Eskers are sinuous ridges 0.1 - 80 km long, 20 - 500 m wide and 4 - 50 m high laid down by glacial meltwater in tunnels and crevasses in stationary or retreating ice sheets. They are commonly composed of sands and gravels with rounded boulders and cobbles. The gravels are usually bedded and the beds often slump towards the flank of the esker, indicating collapse as the confining ice walls melt. Four types of eskers have been identified in Ireland: (i) Continuous subglacial tunnel fill represents deposition within tunnels underneath or within an ice body originally used as water escape conduits; (ii) Continuous fluvial ice-channel fill deposit in channels cut into the ice on top of the glacier or down to the substrate subsequently infilled by sediments; (iii) Long beads - subglacial tunnel fill are segmented ridges, with a length-width ratio of 5:1 to 10:1, representing sequential deposition near or at the ice margin as the ice sheet retreats; (iv) Short beads are glaciolacustrine deposits interpreted as sequential deposition of ice-contact subaqueous outwash fans. Irish eskers have significant morphological similarities with those identified on Mars providing an opportunity for an insightful morphological and morphometric analysis to determine potential formative environments on Mars. Putative Martian eskers are 2-300 km long, 50-3000 m wide and 10-150 m high. The Irish eskers are similar in scale and present dimensions within these ranges. Eskers in Ireland are composed of sand and gravel with cobbles and boulders. Mars esker-like ridges observed in high

  16. POINT CLOUD ORIENTED SHOULDER LINE EXTRACTION IN LOESS HILLY AREA

    Full Text Available Shoulder line is the significant line in hilly area of Loess Plateau in China, dividing the surface into positive and negative terrain (P-N terrains. Due to the point cloud vegetation removal methods of P-N terrains are different, there is an imperative need for shoulder line extraction. In this paper, we proposed an automatic shoulder line extraction method based on point cloud. The workflow is as below: (i ground points were selected by using a grid filter in order to remove most of noisy points. (ii Based on DEM interpolated by those ground points, slope was mapped and classified into two classes (P-N terrains, using Natural Break Classified method. (iii The common boundary between two slopes is extracted as shoulder line candidate. (iv Adjust the filter gird size and repeat step i-iii until the shoulder line candidate matches its real location. (v Generate shoulder line of the whole area. Test area locates in Madigou, Jingbian County of Shaanxi Province, China. A total of 600 million points are acquired in the test area of 0.23km2, using Riegl VZ400 3D Laser Scanner in August 2014. Due to the limit Granted computing performance, the test area is divided into 60 blocks and 13 of them around the shoulder line were selected for filter grid size optimizing. The experiment result shows that the optimal filter grid size varies in diverse sample area, and a power function relation exists between filter grid size and point density. The optimal grid size was determined by above relation and shoulder lines of 60 blocks were then extracted. Comparing with the manual interpretation results, the accuracy of the whole result reaches 85%. This method can be applied to shoulder line extraction in hilly area, which is crucial for point cloud denoising and high accuracy DEM generation.

    2011-08-01

    Full Text Available PL for SOA proposes, formally, a software engineering methodology, development techniques and support tools for the provision of service product lines. We propose rigorous modeling techniques for the specification and verification of formal notations and languages for service computing with inclinations of variability. Through these cutting-edge technologies, increased levels of flexibility and adaptivity can be achieved. This will involve developing semantics of variability over behavioural models of services. Such tools will assist organizations to plan, optimize and control the quality of software service provision, both at design and at run time by making it possible to develop flexible and cost-effective software systems that support high levels of reuse. We tackle this challenge from two levels. We use feature modeling from product line engineering and, from a services point of view, the orchestration language Orc. We introduce the Smart Grid as the service product line to apply the techniques to.

  19. Spin-lattice relaxation attenuation coefficients for on-line nuclear orientation experiments

    CERN Document Server

    Vénos, D; Severijns, N

    2003-01-01

    In on-line nuclear orientation experiments the relaxation process is of great importance. During implantation of the radioactive beam, the nuclear sublevel populations attain a secular equilibrium. For this case secular orientation parameters are introduced: B sublambda(sec)=rho sublambda B sublambda(th). Previously attenuation coefficients rho sublambda have already been tabulated, but only for lambda=2,4. In the last few years the number of nuclear orientation experiments in which beta or alpha particles are studied has increased. For these experiments the terms with lambda=1,3,6, and 8 are also necessary. Therefore, we have calculated the values of rho sublambda in full scope.

    2014-07-01

    The light scattering properties of a horizontally and vertically oriented spheroidal particle under laser illumination are experimentally investigated using digital in-line holography. The reconstructed wave field shows the bright singular points as a result of the condensed beam formed by a transparent spheroidal particle acting as a lens. The in-plane (θ) and out-of-plane (ϕ) rotating angles of an arbitrarily oriented spheroidal particle are measured by using these scattering properties. As a feasibility test, the 3D orientation of a transparent spheroidal particle suspended in a microscale pipe flow is successfully reconstructed by adapting the proposed method.

  4. A Sinuous Tumulus over an Active Lava Tube at Klauea Volcano: Evolution, Analogs, and Hazard Forecasts

    Orr, Tim R.; Bleacher, Jacob E.; Patrick, Matthew R.; Wooten, Kelly M.

    2015-01-01

    Inflation of narrow tube-fed basaltic lava flows (tens of meters across), such as those confined by topography, can be focused predominantly along the roof of a lava tube. This can lead to the development of an unusually long tumulus, its shape matching the sinuosity of the underlying lava tube. Such a situation occurred during Klauea Volcanos (Hawaii, USA) ongoing East Rift Zone eruption on a lava tube active from July through November 2010. Short-lived breakouts from the tube buried the flanks of the sinuous, ridge-like tumulus, while the tumulus crest, its surface composed of lava formed very early in the flows emplacement history, remained poised above the surrounding younger flows. At least several of these breakouts resulted in irrecoverable uplift of the tube roof. Confined sections of the prehistoric Carrizozo and McCartys flows (New Mexico, USA) display similar sinuous, ridge-like features with comparable surface age relationships. We contend that these distinct features formed in a fashion equivalent to that of the sinuous tumulus that formed at Kilauea in 2010. Moreover, these sinuous tumuli may be analogs for some sinuous ridges evident in orbital images of the Tharsis volcanic province on Mars. The short-lived breakouts from the sinuous tumulus at Kilauea were caused by surges in discharge through the lava tube, in response to cycles of deflation and inflation (DI events) at Kilauea's summit. The correlation between DI events and subsequent breakouts aided in lava flow forecasting. Breakouts from the sinuous tumulus advanced repeatedly toward the sparsely populated Kalapana Gardens subdivision, destroying two homes and threatening others. Hazard assessments, including flow occurrence and advance forecasts, were relayed regularly to the Hawai?i County Civil Defense to aid their lava flow hazard mitigation efforts while this lava tube was active.

    Facial asymmetries in features such as lip commissure and interpupillary plane canting have been described as common conditions affecting smile esthetics. When presented with these asymmetries, the clinician must choose the reference line with which to orient the transverse occlusal plane of the planned dental restorations. The purpose of the online survey described in this study was to determine lay preferences regarding the transverse occlusal plane orientation in faces that display a cant of the commissure line viewed from the frontal perspective. From a digitally created symmetrical facial model with the transverse occlusal plane and commissure line parallel to the interpupillary line (horizontal) and a model constructed in a previous study (control), a new facial model was created with 3 degrees of cant of the commissure line. Three digital tooth mountings were designed with different transverse occlusal plane orientations: parallel to the interpupillary line (A), parallel to the commissure line (B), and the mean angulation plane formed between the interpupillary and commissure line (C), resulting in a total of 4 images. All images, including the control, were organized into 6 pairs and evaluated by 247 selected laypersons through an online Web site survey. Each participant was asked to choose the more attractive face from each of the 6 pairs of images. The control image was preferred by 72.9% to 74.5% of the participants compared with the other 3 images, all of which represented a commissure line cant. Among the 3 pairs which represent a commissure line cant, 59.1% to 61.1% preferred a transverse plane of occlusion cant (B and C) compared with a plane of occlusion parallel to the interpupillary, line and 61.1% preferred a plane of occlusion parallel to the commissure line (B) compared with the mean angulation plane (C). Laypeople prefer faces with a commissure line and transverse occlusal plane parallel to the horizontal plane or horizon. When faces present a

    1980-01-01

    An account is given of an Israeli study of two line sources, one composed of 10 and the other of 20 individual sources. The height of release ranged from 15.7 to 39.6 m, with a uniform rate of release of a gaseous pollutant of 1 Ci/s for each source. Average pollutant concentration was plotted as a function of the rotation angle of the line sources. Reduction of pollutant concentration by a particular rotation of the line sources attained values of up to 50%. At certain rotation angles of the line sources, the environmental concentration was lower even as compared with a single high source. Results also depended on atmospheric conditions. It is suggested that considering the increase in cost of augmenting the height of release as a means of reducing the air pollutant concentration, determination of the optimum geometric orientation of the line sources should be considered as an economical means of improving environmental air quality.

    Neutral lower limb alignment does not necessarily produce a horizontal joint line after total knee arthroplasty (TKA). The orientation of the pre- and postoperative tibial mechanical axes (TMAs-G), tibial component, and joint line relative to the ground were evaluated. The study group included 46 knees, 23 posterior-stabilized (PS) and 23 bicruciate-stabilized (BCS) TKAs. Using whole-leg standing radiographs, the static orientation of the pre- and postoperative TMAs-G and the tibial component as well as the postoperative alignment were measured. Applying image-matching techniques, the dynamic coronal orientation of the tibial component and joint line over the stance phase of gait were analysed. The correlation between static and dynamic orientation of the tibial component and differences in the joint line between the PS and BCS TKAs were evaluated. In standing, the postoperative TMA-G (0.8° ± 2.8°) and tibial component (1.5° ± 2.4°) were laterally tilted with a strong correlation. The preoperative lateral tilt of the TMA-G (7.9° ± 5.1°) was a significant predictor of the postoperative TMA-G. The lateral tilt of the tibial component increased to 5.1° ± 2.4° on dynamic analysis, and was moderately correlated to static orientation. The dynamic orientation of the joint line was smaller for the BCS (1.8° ± 2.4°) compared to the PS (5.5° ± 2.7°) TKA. Even with a mechanically well-aligned TKA, a lateral tilt of the tibial component was identified due to the lateral tilt of the postoperative TMA-G and the stance phase of gait. The BCS can better accommodate the residual lateral tilt of the joint line due to the 3° medial inclination of the joint surfaces of the implant. This study increases the awareness of surgeons regarding the possibility of the coronal joint line orientation to influence preoperative TMA-G and be accommodated by articular surface design, even in mechanically aligned TKA.

    1997-01-01

    This report deals with the object-oriented model development of a neuro-controller design for permanent magnet (PM) dc motor drives. The system under study is described as a collection of interacting objects. Each object module describes the object behaviors, called methods. The characteristics of the object are included in its variables. The knowledge of the object exists within its variables, and the performance is determined by its methods. This structure maps well to the real world objects that comprise the system being modeled. A dynamic learning architecture that possesses the capabilities of simultaneous on-line identification and control is incorporated to enforce constraints on connections and control the dynamics of the motor. The control action is implemented "on-line", in "real time" in such a way that the predicted trajectory follows a specified reference model. A design example of controlling a PM dc motor drive on-line shows the effectiveness of the design tool. This will therefore be very useful in aerospace applications. It is expected to provide an innovative and noval software model for the rocket engine numerical simulator executive.

    Full Text Available In this paper, the design methodology for a skew line gear pair oriented to additive manufacturing technology, with an one-tooth driving line gear and its coupled driven line gear, used for the conventional powered transmission, is researched based on strength analysis. First, the expressions of meshing forces on the line tooth of line gears are deduced; the deformations and stresses of existing structures of a line gear pair are analyzed by using ANSYS Workbench. Then, the reliable structure and the parameters standardization formulae of a line gear pair are deduced by stiffness and strength analyses. Finally, a design case shows that the proposed design methods provide a convenient and reasonable design tool for designing a skew line gear pair in conventional powered transmission field.

    Inflation of narrow tube-fed basaltic lava flows (tens of meters across), such as those confined by topography, can be focused predominantly along the roof of a lava tube. This can lead to the development of an unusually long tumulus, its shape matching the sinuosity of the underlying lava tube. Such a situation occurred during Kīlauea Volcano's (Hawai'i, USA) ongoing East Rift Zone eruption on a lava tube active from July through November 2010. Short-lived breakouts from the tube buried the flanks of the sinuous, ridge-like tumulus, while the tumulus crest, its surface composed of lava formed very early in the flow's emplacement history, remained poised above the surrounding younger flows. At least several of these breakouts resulted in irrecoverable uplift of the tube roof. Confined sections of the prehistoric Carrizozo and McCartys flows (New Mexico, USA) display similar sinuous, ridge-like features with comparable surface age relationships. We contend that these distinct features formed in a fashion equivalent to that of the sinuous tumulus that formed at Kīlauea in 2010. Moreover, these sinuous tumuli may be analogs for some sinuous ridges evident in orbital images of the Tharsis volcanic province on Mars. The short-lived breakouts from the sinuous tumulus at Kīlauea were caused by surges in discharge through the lava tube, in response to cycles of deflation and inflation (DI events) at Kīlauea's summit. The correlation between DI events and subsequent breakouts aided in lava flow forecasting. Breakouts from the sinuous tumulus advanced repeatedly toward the sparsely populated Kalapana Gardens subdivision, destroying two homes and threatening others. Hazard assessments, including flow occurrence and advance forecasts, were relayed regularly to the Hawai'i County Civil Defense to aid their lava flow hazard mitigation efforts while this lava tube was active.

    In medical X-ray Computed Tomography (CT), the use of two distinct X-ray source spectra (energies) allows dose-reduction and material discrimination relative to that achieved with only one source spectrum. Existing dual-energy CT methods include source kVp-switching, double-layer detection, dual-source gantry, and two-pass scanning. Each method suffers either from strong spectral correlation or patient-motion artifacts. To simultaneously address these problems, we propose to improve CT data acquisition with the Grating Oriented Line-wise Filtration (GOLF) method, a novel X-ray filter that is placed between the source and patient. GOLF uses a combination of absorption and filtering gratings that are moved relative to each other and in synchronization with the X-ray tube kVp-switching process and/or the detector view-sampling process. Simulation results show that GOLF can improve the spectral performance of kVp-switching to match that of dual-source CT while avoiding patient motion artifacts and dual imaging chains. Although significant flux is absorbed by this pre-patient filter, the proposed GOLF method is a novel path for cost-effectively extracting dual-energy or multi-energy data and reducing radiation dose with or without kVp switching.

  13. Growth of sinuous waves on thin liquid sheets: Comparison of predictions with experiments

    A recent theory [M. S. Tirumkudulu and M. Paramati, "Stability of a moving radial liquid sheet: Time dependent equations," Phys. Fluids 25(10), 102-107 (2013)] has shown that a radially expanding liquid sheet is unstable to sinuous wave disturbances due to the thinning of the liquid sheet while ignoring the presence of a surrounding gas phase. In this work, we compare the predictions of the aforementioned theory with the measurements of Crapper et al. ["Large amplitude Kelvin-Helmholtz waves on thin liquid sheets," Proc. R. Soc. London, Ser. A 342(1629), 209-224 (1975)] who measured the amplitude and spatial growth rates of sinuous waves induced in radially expanding liquid sheets produced by fan spray nozzles. The predicted growth rates are remarkably close to the measurements over a range of forcing frequencies and amplitudes even though the experiments were performed in the presence of a surrounding gas phase. This is in contrast to large discrepancies observed by Crapper et al. when the same measurements were compared with the predictions of a spatial stability analysis for a moving liquid sheet that accounts for the inertia of the surrounding gas phase but ignores the thickness variation of the sheet.

  14. Triclade: influence of a sinuous secondary instability on the Richtmyer-Meshkov instabilities

    Occurrence of a secondary instability developing after the Richtmyer-Meshkov (primary) instability is emphasized thanks to numerical simulations with the TRICLADE code. We are mainly considering 2D perturbations describes by trigonometric function cosine or [cosine]. However, the 3D case is also tackled. The sinuous secondary instability is characterized by the loss of the symmetries in the direction normal to the interface at its crests. It reduces the late time growing rate of the 'mushrooms' formed by the Richtmyer-Meshkov instability. Related simplified problems, like symmetrical Riemann problems or the Mallier-Maslowe array of counter-rotating vortices, allow us to perform 2D linear stability analysis. Thus, we show that the sinuous secondary instability is not a numerical artifact and that is comes from the continuous incompressible velocity field in the interface region. This instability implies temporal limitations for the validity of single mode simulations; therefore multimode simulations are necessary to study the ]ate-time behaviour of interfaces bitted by shocks.

    Visual line following in mobile robotics can be made more complex when objects are places on or around the line being followed. An algorithm is presented that suggests a manner in which a good line track can be discriminated from a bad line track using the expected size of the line. The mobile robot in this case can determine the size of the width of the line. It calculates a mean size for the line as it moves and maintains a set size of samples, which enable it to adapt to changing conditions. If a measurement is taken that falls outside of what is to be expected by the robot, then it treats the measurement as undependable and as such can take measures to deal with what it believes to be erroneous data. Techniques for dealing with erroneous data include attempting to look around the obstacle or making an educated guess as to where the line should be. The system discussed has the advantage of not needing to add any extra equipment to discover if an obstacle is corrupting its measurements. Instead, the robot is able to determine if data is good ro bad based upon what it expects to find.

  16. The Morphometry of the Deep-Water Sinuous Mendocino Channel and the Immediate Environs, Northeastern Pacific Ocean

    2017-11-01

    Full Text Available Mendocino Channel, a deep-water sinuous channel located along the base of Gorda Escarpment, was for the first time completely mapped with a multibeam echosounder. This study uses newly acquired multibeam bathymetry and backscatter, together with supporting multichannel seismic and sediment core data to quantitatively describe the morphometry of the entire Mendocino Channel and to explore the age and possible causes that may have contributed to the formation and maintenance of the channel. The first 42 km of the channel is a linear reach followed for the next 83.8 km by a sinuous reach. The sinuous reach has a sinuosity index of 1.66 before it changes back to a linear reach for the next 22.2 km. A second sinuous reach is 40.2 km long and the two reaches are separated by a crevasse splay and a large landslide that deflected the channel northwest towards Gorda Basin. Both sinuous reaches have oxbow bends, cut-off meanders, interior and exterior terraces and extensive levee systems. The lower sinuous reach becomes more linear for the next 22.2 km before the channel relief falls below the resolution of the data. Levees suddenly decrease in height above the channel floor mid-way along the lower linear reach close to where the channel makes a 90° turn to the southwest. The entire channel floor is smooth at the resolution of the data and only two large mounds and one large sediment pile were found on the channel floor. The bathymetry and acoustic backscatter, together with previously collected seismic data and box and piston cores provide details to suggest Mendocino Channel may be no older than early Quaternary. A combination of significant and numerous earthquakes and wave-loading resuspension by storms are the most likely processes that generated turbidity currents that have formed and modified Mendocino Channel.

    Sinuous, branching networks of topographic ridges resembling river networks are common across Mars, and show promise for quantifying ancient martian surface hydrology. There are two leading formation mechanisms for ridges with a fluvial origin. Inverted channels are ridges that represent casts (e.g., due to lava fill) of relict river channel topography, whereas exhumed channel deposits are eroded remnants of a more extensive fluvial deposit, such as a channel belt. The inverted channel model is often assumed on Mars; however, we currently lack the ability to distinguish these ridge formation mechanisms, motivating the need for Earth-analog study. To address this issue, we studied the extensive networks of sinuous ridges in the Ebro basin of northeast Spain. The Ebro ridges stand 3-15 meters above the surrounding plains and are capped by a cliff-forming sandstone unit 3-10 meters thick and 20-50 meters in breadth. The caprock sandstone bodies contain bar-scale cross stratification, point-bar deposits, levee deposits, and lenses of mudstone, indicating that these are channel-belt deposits, rather than casts of channels formed from lateral channel migration, avulsion and reoccupation. In plan view, ridges form segments branching outward to the north resembling a distributary network; however, crosscutting relationships indicate that ridges cross at different stratigraphic levels. Thus, the apparent network in planview reflects non-uniform exhumation of channel-belt deposits from multiple stratigraphic positions, rather than an inverted coeval river network. As compared to the inverted channel model, exhumed fluvial deposits indicate persistent fluvial activity over geologic timescales, indicating the potential for long-lived surface water on ancient Mars.

    In this paper, we focus on UAV-borne laser scanning with the objective of densely sampling object surfaces in the local surrounding of the UAV. In this regard, using a line scanner which scans along the vertical direction and perpendicular to the flight direction results in a point cloud with low point density if the UAV moves fast. Using a line scanner which scans along the horizontal direction only delivers data corresponding to the altitude of the UAV and thus a low scene coverage. For these reasons, we present a concept and a system for UAV-borne laser scanning using multiple line scanners. Our system consists of a quadcopter equipped with horizontally and vertically oriented line scanners. We demonstrate the capabilities of our system by presenting first results obtained for a flight within an outdoor scene. Thereby, we use a downsampling of the original point cloud and different neighborhood types to extract fundamental geometric features which in turn can be used for scene interpretation with respect to linear, planar or volumetric structures.

  2. Quasar emission lines as probes of orientation: implications for disc wind geometries and unification

    The incidence of broad absorption lines (BALs) in quasar samples is often interpreted in the context of a geometric unification model consisting of an accretion disc and an associated outflow. We use the Sloan Digital Sky Survey quasar sample to test this model by examining the equivalent widths (EWs) of C IV 1550 Å, Mg II 2800 Å, [O III] 5007 Å and C III] 1909 Å. We find that the emission line EW distributions in BAL and non-BAL quasars are remarkably similar - a property that is inconsistent with scenarios in which a BAL outflow rises equatorially from a geometrically thin, optically thick accretion disc. We construct simple models to predict the distributions from various geometries; these models confirm the above finding and disfavour equatorial geometries. We show that obscuration, line anisotropy and general relativistic effects on the disc continuum are unlikely to hide an EW inclination dependence. We carefully examine the radio and polarization properties of BAL quasars. Both suggest that they are most likely viewed (on average) from intermediate inclinations, between type 1 and type 2 active galactic nuclei (AGN). We also find that the low-ionization BAL quasars in our sample are not confined to one region of the 'Eigenvector 1' parameter space. Overall, our work leads to one of the following conclusions, or some combination thereof: (I) the continuum does not emit like a geometrically thin, optically thick disc; (II) BAL quasars are viewed from similar angles to non-BAL quasars, that is, low inclinations and (III) geometric unification does not explain the fraction of BALs in quasar samples.

    This study investigated the positional relation of the commissure line of the mouth to the maxillary first molars. Thirty-five volunteers, 20 to 40 years old, with normal natural dentitions were recruited. Maxillary casts with marks locating the commissure were digitally scanned to measure the vertical distance from the tip to the base of the mesiofacial cusp (CO) and from the tip to the mark (CM). There was no significant difference (t test; P > .05) between the CO (1.61 ± 0.41 mm) and CM (1.14 ± 0.68 mm). The mean distance of the commissure mark from the occlusal plane was 0.78 mm.

    The use of the ala-tragus line (ATL) to orient the occlusal plane (OP) is controversial because there is a lack of agreement on the exact points of reference for this line. This study determined the relationship between the natural OP and ATL which was established by using the inferior border of the ala of the nose and (1) the superior border of the tragus (ATL1), (2) the tip (ATL2), and (3) the inferior border of the tragus (ATL3). Lateral cephalometric radiographs were taken of each subject by a standard method and tracings were obtained on acetate paper to show the OP and the three ala-tragus lines. The relationship between the OP and each of ATL was measured for each subject. Mean and standard deviation values were then calculated for the relationship. Statistical analysis was performed using repeated measure analysis of variance followed by Bonferroni pairwise comparisons and Student's t-test (α = 0.05). Significant differences were noted between the three mean angles (p = 0.046). The mean angle (3.275 degrees ± 2.54) formed by OP and ATL2 was significantly the smallest (p occlusal plane.

    A precise value for the magnetic moment of the 69 As 5/2 - ground state has been obtained from nuclear magnetic resonance on oriented nuclei (NMR/ON) using the NICOLE 3 He- 4 He dilution refrigerator setup at ISOLDE/CERN. The NMR/ON signal was observed by monitoring the anisotropy of the 69 As β particles. The center frequency ν[B ext =0.0994(10)T]=169.98(9) MHz corresponds to μ[ 69 As]=+1.6229(16)μ N . This result differs considerably from the πf 5/2 single-particle value obtained with g factors for a free proton but is in reasonable agreement with the value obtained with effective g factors and with values from a core polarization calculation and from calculations in the framework of the interacting boson-fermion model. Assuming a single exponential spin-lattice relaxation behavior a relaxation time T 1 ' =10(25) s was observed for 69 AsFe -bar at a temperature of about 20 mK in a magnetic field B=0.1 T

    In [2], H ardt, L in and the author proved that the defect set of minimizers of the modified Ericksen energy for nematic liquid crystals consists locally of a finite union of isolated points and Hölder continuous curves with finitely many crossings. In this article, we show that each Hölder continuous curve in the defect set is of finite length. Hence, locally, the defect set is rectifiable. For the most part, the proof closely follows the work of D e L ellis et al. (Rectifiability and upper minkowski bounds for singularities of harmonic q-valued maps, arXiv:1612.01813, 2016) on harmonic Q-valued maps. The blow-up analysis in A lper et al. (Calc Var Partial Differ Equ 56(5):128, 2017) allows us to simplify the covering arguments in [11] and locally estimate the length of line defects in a geometric fashion.

  7. Effects of a flood pulse on exchange flows along a sinuous stream

    Flood pulses are important events for river ecosystems: they create hydrological interactions at the terrestrial/aquatic interface that fuel biological productivity and shape the hyporheic-riparian habitats. For example, floods promote faunal activity and decomposition by increasing the supply of oxygenated water in downwelling areas, while the following recession periods tend to provide stable thermal conditions favoured by fish or insects in areas of groundwater upwelling. This 3-D modelling study investigates the effect of stream stage transience (with events characterised by their intensity and duration) on hydrological exchanges between the surface and the near-stream subsurface. It evaluates, in particular, its effect on streams of varying sinuosity by quantifying the dynamic response of: (1) subsurface flow paths, (2) the exchange pattern at the sediment-water interface, and (3) integrative measures such as total exchange flux and total storage. Understanding geomorphological controls on groundwater/surface water interactions is attractive because topography is generally better constrained than subsurface parameters, and can be used in data-poor situations. The numerical model represents a hypothetical alluvial plain limited by impervious bedrock on all four sides, and in which the channel meanders according to the sine-generated curve of Langbein and Leopold (1966). As the model (HydroGeoSphere) couples surface and subsurface flow, the stream stage transience is imposed by a fluctuating head at the channel inlet. Preliminary results show that a simple rectangular flood pulse in an idealised sinuous stream without additional complexity can generate multiple flow direction reversals at a single point in the channel. The initial conditions of the groundwater table, the channel sinuosity and the time characteristics of the flood pulse all control exchange flow features in different ways. Results are also compared with 'bank storage' analytical solutions that

    The Tharsis Montes rift aprons are composed of outpourings of lava from chaotic terrains to the northeast and southwest flank of each volcano. Sinuous and branching channel networks that are present on the rift aprons suggest the possibility of fluvial processes in their development, or erosion by rapidly emplaced lavas, but the style of lava flow emplacement throughout rift apron development is not clearly understood. To better characterize the style of lava emplacement and role of fluvial processes in rift apron development, we conducted morphological mapping of the Pavonis Mons southwest rift apron and the eastern Tharsis plains using images from the High Resolution Imaging Science Experiment (HiRISE), Mars Orbiter Camera (MOC), Context Camera (CTX), Thermal Emission Imaging System (THEMIS), and High Resolution Stereo Camera (HRSC) along with the Mars Orbiter Laser Altimeter (MOLA) Precision Experiment Data Records (PEDRs) and gridded data. Our approach was to: (1) search for depositional fans at the slope break between the rift apron and adjacent low slope plains; (2) determine if there is evidence that previously formed deposits might have been buried by plains units; (3) characterize the Tharsis plains morphologies east of Pavonis Mons; and (4) assess their relationship to the rift apron units. We have not identified topographically significant depositional fans, nor did we observe evidence to suggest that plains units have buried older rift apron units. Flow features associated with the rift apron are observed to continue across the slope break onto the plains. In this area, the plains are composed of a variety of small fissures and low shield vents around which broad channel-fed and tube-fed flows have been identified. We also find broad, flat-topped plateaus and sinuous ridges mixed among the channels, tubes and vents. Flat-topped plateaus and sinuous ridges are morphologies that are analogous to those observed on the coastal plain of Hawai'i, where lava

  9. New evidence of genetic factors influencing sexual orientation in men: female fecundity increase in the maternal line.

    There is a long-standing debate on the role of genetic factors influencing homosexuality because the presence of these factors contradicts the Darwinian prediction according to which natural selection should progressively eliminate the factors that reduce individual fecundity and fitness. Recently, however, Camperio Ciani, Corna, and Capiluppi (Proceedings of the Royal Society of London, Series B: Biological Sciences, 271, 2217-2221, 2004), comparing the family trees of homosexuals with heterosexuals, reported a significant increase in fecundity in the females related to the homosexual probands from the maternal line but not in those related from the paternal one. This suggested that genetic factors that are partly linked to the X-chromosome and that influence homosexual orientation in males are not selected against because they increase fecundity in female carriers, thus offering a solution to the Darwinian paradox and an explanation of why natural selection does not progressively eliminate homosexuals. Since then, new data have emerged suggesting not only an increase in maternal fecundity but also larger paternal family sizes for homosexuals. These results are partly conflicting and indicate the need for a replication on a wider sample with a larger geographic distribution. This study examined the family trees of 250 male probands, of which 152 were homosexuals. The results confirmed the study of Camperio Ciani et al. (2004). We observed a significant fecundity increase even in primiparous mothers, which was not evident in the previous study. No evidence of increased paternal fecundity was found; thus, our data confirmed a sexually antagonistic inheritance partly linked to the X-chromosome that promotes fecundity in females and a homosexual sexual orientation in males.

    Fine cell-adhesion patterning and nuclei orientation control on silicone rubber were investigated by limiting line-width of carbon negative-ion implantation. The ions were implanted at 3×1015 ions/cm2 and 10 keV through masks of ridge-pattern and rectangle-pattern with various slit apertures of 0-40 μm in width. After 2 days culture, nuclei of rat mesenchymal stem cells were stained with fluorescent dye to evaluate the nuclei positions at each tip ridge-region and the relative angles between the major axis of ellipse-shape nuclei and the implanted line-region. Results showed the individual nucleus arrangement along the narrow line-widths of 3-12 μm and the gathered one on the wider line-width. Number of nuclei orientation in the angle range of 0°-10° increased to 79% on the line-width of 10 μm. As a result, the fine cell-adhesion patterning and nuclei orientation could be achieved by decreasing the implanted line-width to 10 μm.

    In this work, crystallographic orientation of polycrystalline silicon films on glass formed by continuous wave diode laser crystallization was studied. Most of the grain boundaries were coincidence lattice Σ3 twin boundaries and other types of boundaries such as, Σ6, Σ9, and Σ21 were also frequently observed. The highest photoluminescence signal and mobility were observed for a grain with (100) orientation in the normal direction. X-ray diffraction results showed the highest occupancies between 41 and 70% along the (110) orientation. However, the highest occupancies changed to (100) orientation when a 100 nm thick SiO{sub x} capping layer was applied. Suns-Voc measurement and photoluminescence showed that higher solar cell performance is obtained from the cell crystallized with the capping layer, which is suspected from increased occupancies of (100) orientation. - Highlights: • Linear grains parallel to the scan direction formed with high density. • Σ3 coincidence lattice (CSL) boundaries found inside a grain • Grain boundaries exhibit various CSL boundaries such as Σ9, Σ18, and Σ27. • Grain with < 100 > orientation in normal direction showed highest electrical properties. • Improved voltage observed when percentage of < 100 > normal orientation is increased.

    Full Text Available The perception of elements in a system often creates their interdependence, interconditionality, and suppression. The lines from a basic geometrical element have become the model of a reductive world based on isolation according to certain criteria such as function, structure, and social organization. Their traces are experienced in the contemporary world as fragments or ruins of a system of domination of an assumed hierarchical unity. How can one release oneself from such dependence or determinism? How can the lines become less “systematic” and forms more autonomous, and less reductive? How is a form released from modernistic determinism on the new controversial ground? How can these elements or forms of representation become forms of action in the present complex world? In this paper, the meaning of lines through the ideas of Le Corbusier, Leonidov, Picasso, and Hitchcock is presented. Spatial research was made through a series of examples arising from the projects of the architectural studio “Residential Transformations”, which was a backbone for mapping the possibilities ranging from playfulness to exactness, as tactics of transformation in the different contexts of the contemporary world.

    A block copolymer film having a line pattern with a high degree of long-range order is formed by a method that includes forming a block copolymer film on a substrate surface with parallel facets, and annealing the block copolymer film to form an annealed block copolymer film having linear microdomains parallel to the substrate surface and orthogonal to the parallel facets of the substrate. The line-patterned block copolymer films are useful for the fabrication of magnetic storage media, polarizing devices, and arrays of nanowires.

    Free-ranging marine predators rarely search for prey along straight lines because dynamic ocean processes usually require complex search strategies. If linear movement patterns occur they are usually associated with travelling events or migratory behaviour. However, recent fine scale tracking of flying seabirds has revealed straight-line movements while birds followed fishing vessels. Unlike flying seabirds, penguins are not known to target and follow fishing vessels. Yet yellow-eyed penguins from New Zealand often exhibit directed movement patterns while searching for prey at the seafloor, a behaviour that seems to contradict common movement ecology theories. While deploying GPS dive loggers on yellow-eyed penguins from the Otago Peninsula we found that the birds frequently followed straight lines for several kilometres with little horizontal deviation. In several cases individuals swam up and down the same line, while some of the lines were followed by more than one individual. Using a remote operated vehicle (ROV) we found a highly visible furrow on the seafloor most likely caused by an otter board of a demersal fish trawl, which ran in a straight line exactly matching the trajectory of a recent line identified from penguin tracks. We noted high abundances of benthic scavengers associated with fisheries-related bottom disturbance. While our data demonstrate the acute way-finding capabilities of benthic foraging yellow-eyed penguins, they also highlight how hidden cascading effects of coastal fisheries may alter behaviour and potentially even population dynamics of marine predators, an often overlooked fact in the examination of fisheries' impacts.

    A rotor flux state observer considering iron loss, for an Induction Motor (IM), is proposed. The aim of this proposal is to avoid detuning caused by the IM iron loss on a field-oriented control (FOC). An adaptive scheme for the K{sub Fe}, a parameter that represents the IM iron loss, is also proposed. The main objective of this scheme is to improve the dynamic response of control by compensating the variations of iron losses due to possible variations in the stator core characteristics. Simulation results demonstrated that the observer and the adaptive scheme showed a good performance fulfilling then the objectives. (author)

  19. POINT CLOUD ANALYSIS FOR UAV-BORNE LASER SCANNING WITH HORIZONTALLY AND VERTICALLY ORIENTED LINE SCANNERS – CONCEPT AND FIRST RESULTS

    2017-08-01

    Full Text Available In this paper, we focus on UAV-borne laser scanning with the objective of densely sampling object surfaces in the local surrounding of the UAV. In this regard, using a line scanner which scans along the vertical direction and perpendicular to the flight direction results in a point cloud with low point density if the UAV moves fast. Using a line scanner which scans along the horizontal direction only delivers data corresponding to the altitude of the UAV and thus a low scene coverage. For these reasons, we present a concept and a system for UAV-borne laser scanning using multiple line scanners. Our system consists of a quadcopter equipped with horizontally and vertically oriented line scanners. We demonstrate the capabilities of our system by presenting first results obtained for a flight within an outdoor scene. Thereby, we use a downsampling of the original point cloud and different neighborhood types to extract fundamental geometric features which in turn can be used for scene interpretation with respect to linear, planar or volumetric structures.

    A 3-chamber in-line olfactometer designed for use with sand flies is described and tested as a high-throughput method to screen honeys for attractiveness to Phlebotomus papatasi (four geographic isolates), P. duboscqi (two geographic isolates), and Lutzomyia longipalpis maintained in colonies at the Walter Reed Army Institute of Research. A diversity of unifloral honey odors were evaluated as a proxy for the natural floral odors that sand flies may use in orientation to floral sugar sources in the field. In the 3-chamber in-line olfactometer, the choice modules come directly off both sides of the release area instead of angling away as in the Y-tube olfactometer. Of the 25 honeys tested, five had a significant attraction for one or more of the sand fly isolates tested. This olfactometer and high-throughput method has utility for evaluating a diversity of natural materials with unknown complex odor blends that can then be down-selected for further evaluation in wind tunnels and/or field scenarios. © 2014 The Society for Vector Ecology.

    Although many extant normative data sets for standardized neuropsychometric instruments feature adjustments for subject variables, there are reasons to believe that improvements in interpretive accuracy that result from such adjustments are less than optimal. In particular, several theoretical considerations suggest that years of formal education may be less closely related to test performances than is general intellectual functioning. In this first of four reanalyses of results from the Mayo Clinic's Older Americans Normative Studies (MOANS) databases, age-adjusted scores on the Boston Naming Test, the MAE Token Test, and the Judgment of Line Orientation Test were indeed found to be more strongly associated with Mayo Age-adjusted WAIS-R Full Scale IQ scores (rs=.608, .473, and .502, respectively) than with education (rs=.310, .306, and .236, respectively) for healthy older examinees (56-99 years). Consistent with the remarks of Dodrill (19971999), these correlations generally decreased at higher levels of intelligence. The magnitude and pattern of such declines varied across the three tests, however, suggesting that IQ-test score associations must be empirically determined rather than assumed to be linear. Tables of Age- and IQ-Adjusted percentile equivalents of MOANS Age-adjusted BNT, Token Test, and JLO scaled scores are presented for eleven age ranges and seven IQ ranges. The article concludes with a discussion of factors that may underlie observed relations among age, intelligence, and neuropsychometric test performances.

    Visuospatial deficits have been described in Huntington's disease (HD); however, the extent of these deficits remains unclear. The Benton Judgment of Line Orientation (JoLO) Test, commonly used to assess visuospatial ability, requires minimal motor involvement. It has demonstrated sensitivity to visuospatial deficits in Parkinson's disease; however, few studies have examined performance on this test in HD. The objective of the current study was to assess visuospatial ability in premanifest and manifest HD using the JoLO. A global cognitive measure, the Mattis Dementia Rating Scale (DRS), was used to stratify manifest HD patients as mild (DRS ≥129) vs. moderate-severe (DRS ≤128). Fifty mild, 42 moderate-severe, and 30 premanifest HD subjects, as well as 35 matched controls, were administered the JoLO. HD Burden of Pathology (BOP) scores were used as a measure of disease severity. Results revealed that the total manifest HD sample (p visuospatial deficits across various stages of manifest HD. However, any visuospatial impairment that might be present during the premanifest stage of HD was not detected using the JoLO in the present sample.

  7. Square to hexagonal symmetry transition of the flux line lattice in YNi2B2C for different field orientations

    Using small-angle neutron scattering we have studied the magnetic flux line lattice in YNi2B2C with the field rotated 30(:) away from the crystalline c-axis. Previously we have reported on a square to hexagonal symmetry transition of the fluc line lattice below 1 kOe for H parallel to c. We find...... that the rotation of the field shifts the transition to higher fields in agreement with theoretical prediction. Two different directions in the ab-plane were chosen as axes of rotation. Rotating the field around [1,1,0] shifts the onset of the transition up to 3 kOe. Rotating the field around [1,0,0] stabilizes...

    radiation. The major results of the systematic work on optical orientation, both experimental and theoretical, at the Ioffe Institute and the Ecole Normale Supérieure in Paris are documented in the book Optical Orientation, edited by F Meier and B P Zakharchenya in the series Modern Problems in Condensed Matter Sciences [4], in which the foundations of optical orientation are comprehensively presented by renowned authors. This book is still the unsurpassed standard work in the field. If one asks what has become new since that publication in 1984 it is obviously the arrival of low-dimensional structures, two-dimensional heterostructures and zero-dimensional quantum dots. It has turned out that the quantum confinement can significantly modify the spin lifetime and the spin relaxation. The experimental work on spin alignment was done by a relative small number of researchers. However, the situation has substantially changed during the last decade. Research on spin-related phenomena has become very popular and the word 'spintronics' was coined. Spin research is no longer considered to be somewhat esoteric, since the replacement of silicon microelectronics based on the electron charge by spin-based electronics is being discussed. Whether these proposals can be realized remains to be seen. But one consequence has been a worldwide increase of high level basic research in spin phenomena. Another line of current research which has contributed to the popularity of spin-related research is quantum computing, based on spin-qubits. To be useful, solid state systems require long spin relaxation times and weak interaction with the environment. This is indispensable for low error rates. The difficulties in achieving these goals have been extensively discussed in the literature. Nowadays, because of the volume and diversity of spin-related work worldwide, a book on optical orientation like that edited by Meyer and Zakharchenya does not seem possible, so in this special issue of

    Occurrence of a secondary instability developing after the Richtmyer-Meshkov (primary) instability is emphasized thanks to numerical simulations with the TRICLADE code. We are mainly considering 2D perturbations describes by trigonometric function cosine or [cosine]. However, the 3D case is also tackled. The sinuous secondary instability is characterized by the loss of the symmetries in the direction normal to the interface at its crests. It reduces the late time growing rate of the 'mushrooms' formed by the Richtmyer-Meshkov instability. Related simplified problems, like symmetrical Riemann problems or the Mallier-Maslowe array of counter-rotating vortices, allow us to perform 2D linear stability analysis. Thus, we show that the sinuous secondary instability is not a numerical artifact and that is comes from the continuous incompressible velocity field in the interface region. This instability implies temporal limitations for the validity of single mode simulations; therefore multimode simulations are necessary to study the ]ate-time behaviour of interfaces bitted by shocks.

In line with this conceptualization, a multidimensional operational measure of exploration orientation is developed and its internal consistency established.

  7. Orienting hypnosis.

    Hope, Anna E; Sugarman, Laurence I

    2015-01-01

    This article presents a new frame for understanding hypnosis and its clinical applications. Despite great potential to transform health and care, hypnosis research and clinical integration is impaired in part by centuries of misrepresentation and ignorance about its demonstrated efficacy. The authors contend that advances in the field are primarily encumbered by the lack of distinct boundaries and definitions. Here, hypnosis, trance, and mind are all redefined and grounded in biological, neurological, and psychological phenomena. Solutions are proposed for boundary and language problems associated with hypnosis. The biological role of novelty stimulating an orienting response that, in turn, potentiates systemic plasticity forms the basis for trance. Hypnosis is merely the skill set that perpetuates and influences trance. This formulation meshes with many aspects of Milton Erickson's legacy and Ernest Rossi's recent theory of mind and health. Implications of this hypothesis for clinical skills, professional training, and research are discussed.

    A descriptive study (based on skeletal material) was designed to measure sacral anatomic orientation (SAO) in individuals with and without spondylolysis. To test whether a relationship between SAO and spondylolysis exists. Spondylolysis is a stress fracture in the pars interarticularis (mainly of L5). The natural history of the phenomenon has been debated for years with opinions divided, i.e., is it a developmental condition or a stress fracture phenomenon. There is some evidence to suggest that sacral orientation can be a "key player" in revealing the etiology of spondylolysis. The pelvis was anatomically reconstructed and SAO was measured as the angle created between the intersection of a line running parallel to the superior surface of the sacrum and a line running between the anterior superior iliac spine (ASIS) and the anterior-superior edge of the symphysis pubis (PUBIS).SAO was measured in 99 adult males with spondylolysis and 125 adult males without spondylolysis. The difference between the groups was tested using an unpaired t test. Spondylolysis prevalence is significantly higher in African-Americans compared to European-Americans: 5.4% versus 2.04% in males (P < 0.001) and 2.31% versus 0.4%, P < 0.001 in females. SAO was significantly lower in the spondylolytic group (44.07 degrees +/- 11.46 degrees) compared to the control group (51.07 degrees +/- 8.46 degrees, P < 0.001). A more horizontally oriented sacrum leads to direct impingement on L5 pars interarticularis by both L4 inferior articular facet superiorly and S1 superior articular facet inferiorly. Repetitive stress due to standing (daily activities) or sitting increases the "pincer effect" on this area, and eventually may lead to incomplete synostosis of the neural arch.

  4. Marketing-oriented organizations: an integrated approach.

    Science.gov (United States)

    Stensrud, R; Arrington, B

    1988-03-01

    Organizations can be oriented toward marketing from a production, product, sales, or marketing perspective. Strategies, structures, and cultures, which reflect a company's basic orientation, must be integrated to ensure that marketing efforts communicate a clear corporate position. In a study of 31 hospitals, the Center for Health Services Education Research, St. Louis University, found that no hospital's organization fit neatly into a single category. For example, a hospital may have some service lines that were marketing oriented while other lines were production oriented. The majority of hospitals, however, were product oriented, focusing on productivity and financial performance rather than on market factors. The most effective sales orientation was observed in the for-profits. Their selling efforts, however, tended to be internally focused, with product development activities divorced from the planning and marketing functions. Only the for-profit hospitals showed the beginning of a marketing orientation. Developing a marketing orientation, especially in line divisions, requires a careful, well-orchestrated effort and the presence of several key factors: Access to capital and an emphasis on long-range planning and strategic spending The availability of hospital-specific market research. Key distribution channels. Talented middle managers. Up-to-date systems and structures equipped to serve new values and strategies. Leaders capable of communicating to the organization a vision of its role in the community.

  6. Symmetric Euler orientation representations for orientational averaging.

    Science.gov (United States)

    Mayerhöfer, Thomas G

    2005-09-01

    A new kind of orientation representation called symmetric Euler orientation representation (SEOR) is presented. It is based on a combination of the conventional Euler orientation representations (Euler angles) and Hamilton's quaternions. The properties of the SEORs concerning orientational averaging are explored and compared to those of averaging schemes that are based on conventional Euler orientation representations. To that aim, the reflectance of a hypothetical polycrystalline material with orthorhombic crystal symmetry was calculated. The calculation was carried out according to the average refractive index theory (ARIT [T.G. Mayerhöfer, Appl. Spectrosc. 56 (2002) 1194]). It is shown that the use of averaging schemes based on conventional Euler orientation representations leads to a dependence of the result from the specific Euler orientation representation that was utilized and from the initial position of the crystal. The latter problem can be overcome partly by the introduction of a weighing factor, but only for two-axes-type Euler orientation representations. In case of a numerical evaluation of the average, a residual difference remains also if a two-axes type Euler orientation representation is used despite of the utilization of a weighing factor. In contrast, this problem does not occur if a symmetric Euler orientation representation is used as a matter of principle, while the result of the averaging for both types of orientation representations converges with increasing number of orientations considered in the numerical evaluation. Additionally, the use of a weighing factor and/or non-equally spaced steps in the numerical evaluation of the average is not necessary. The symmetrical Euler orientation representations are therefore ideally suited for the use in orientational averaging procedures.

  7. A robust line extraction and matching algorithm

    Science.gov (United States)

    Hussien, B.; Sridhar, B.

    1993-01-01

    This paper presents an algorithm for extracting straight lines from intensity mages and describes a line matching algorithm for solving the line correspondence problem. The line extraction process begins by detecting edges in the intensity image. Next, line support regions are formed where image points (pixels) have similar gradient orientation. A line fitting algorithm is then used to fit a line to the points in the line support region based on a least means square fitting algorithm. Finally, line segments are linked together to form the final lines by using an adaptive line linking method; this results in much stronger lines and a smaller set of lines to be considered. Once the lines are detected in a sequence of images, a line matching algorithm is used to match lines in one image to the lines in the other image. The images are either from a motion or stereo sequence. The matched lines may then be used with the sensor position and orientation data to estimate range to objects corresponding to the lines. We present results based on applying the line extraction and line matching algorithms to a synthetic image and an outdoor scene captured by a camera on a helicopter.

  8. Device Oriented Project Controller

    Energy Technology Data Exchange (ETDEWEB)

    Dalesio, Leo; Kraimer, Martin

    2013-11-20

    This proposal is directed at the issue of developing control systems for very large HEP projects. A de-facto standard in accelerator control is the Experimental Physics and Industrial Control System (EPICS), which has been applied successfully to many physics projects. EPICS is a channel based system that requires that each channel of each device be configured and controlled. In Phase I, the feasibility of a device oriented extension to the distributed channel database was demonstrated by prototyping a device aware version of an EPICS I/O controller that functions with the current version of the channel access communication protocol. Extensions have been made to the grammar to define the database. Only a multi-stage position controller with limit switches was developed in the demonstration, but the grammar should support a full range of functional record types. In phase II, a full set of record types will be developed to support all existing record types, a set of process control functions for closed loop control, and support for experimental beam line control. A tool to configure these records will be developed. A communication protocol will be developed or extensions will be made to Channel Access to support introspection of components of a device. Performance bench marks will be made on both communication protocol and the database. After these records and performance tests are under way, a second of the grammar will be undertaken.

  9. Entrepreneurial orientation, market orientation, and competitive environment

    orientation, and competitive environment shape business performance via a three-way interaction. We test the model using primary data from the CEOs of 270 CEO of manufacturing firms, together with secondary data on these firms' profit performance. An assessment of the results indicates that customer...... orientation moderates the positive relationships between the competitiveness element of entrepreneurial orientation and market share and return on assets (ROA): the positive relationships between competitiveness and market share and competitiveness and ROA become stronger the greater the firms' customer...... orientations.

    2006-01-01

    Full Text Available In this article Orientalism, a special hegemonic discourse about "the Orient" by Europeans is discussed by focusing on how it is manifested in a "Western" view of India. Orientalism as a discourse about the Orient is a concept first coined by Edward Said in his book Orientalism (1978 and contains a long history of European way of relating to the Orient as a counterpart of European/Western culture. In this article Orientalist discourses about India by hegemonically Western (and particularly Anglo-Saxon sources are portrayed and the so-called Indo-Orientalist essentialism defining Indianness from the outside analyzed. Moreover, a Indo-Orientalism as an imported ideology to be used in Indian nationalist discourses to emphasize a dichotomy between India and "the West" is discussed.

    A program has been developed for computing the ESR spectrum of a collection of randomly oriented spins subject only to an electronic Zeeman interaction and having a Lorentzian single crystal line shape. Other single crystal line shapes, including numerical solutions of the Bloch equations, can be accommodated with minor modifications. The program differs in several features from those existing elsewhere, thus enabling one to study saturation effects, over-modulation effects, both absorptive and dispersive signals, and second and higher order derivative signals.

  1. Competitiveness through strategic orientation

    Directory of Open Access Journals (Sweden)

    Diego Monferrer

    2012-12-01

    Full Text Available The aim of this paper is to further the study of the factors that influence the international competitive position of international new ventures and, consequently, their international performance. Specifically, we analyze the role of entrepreneurial and market orientations in the international competitive position of such firms. Data were collected at Spanish and Belgian international new ventures. The structural equations model approach was used to test our hypotheses. Both the Spanish and the Belgian sample revealed a positive and significant relationship between entrepreneurial orientation and market orientation. Furthermore, both orientations have a positive and significant effect on the international competitive position of such firms. Finally, any firm’s international competitive position is positively and significantly related to its international performance. The study therefore appears to indicate that, when it comes to international new ventures, the conjunction of these two orientations is a key factor to attaining a superior competitive position and a positive performance in international markets.

    2017-10-01

    The brain can use multiple reference frames to code line orientation, including head-, object-, and gravity-centered references. If these frames change orientation, their representations must be updated to keep register with actual line orientation. We tested this internal updating during head rotation in roll, exploiting the rod-and-frame effect: The illusory tilt of a vertical line surrounded by a tilted visual frame. If line orientation is stored relative to gravity, these distortions should also affect the updating process. Alternatively, if coding is head- or frame-centered, updating errors should be related to the changes in their orientation. Ten subjects were instructed to memorize the orientation of a briefly flashed line, surrounded by a tilted visual frame, then rotate their head, and subsequently judge the orientation of a second line relative to the memorized first while the frame was upright. Results showed that updating errors were mostly related to the amount of subjective distortion of gravity at both the initial and final head orientation, rather than to the amount of intervening head rotation. In some subjects, a smaller part of the updating error was also related to the change of visual frame orientation. We conclude that the brain relies primarily on a gravity-based reference to remember line orientation during head roll.

    Coggins, James M.

    Object-Oriented Programming is enabled by advances in compiler technology and programming language design supporting encapsulation and inheritance. This technical adjustment has had a surprisingly broad impact on strategies for design and development of software. This paper explains what Object-Oriented Programming is, why it has attracted so much interest, and then critically examines its impact. The conclusion is that the optimal use of OOP occurs when application clients are empowered to contribute to the inspection, testing and development of the software they need, in a strategy I call Subject-Oriented Programming. The paper concludes by examining what the next important advance in software technology is likely to be.

    González-García, A. César; Belmonte, Juan Antonio

    The possible astronomical or topographical orientations of the Hittite monuments of the Bronze Age has remained unexplored until recently. This would provide an important insight into how temporality was imprinted by this culture in sacred spaces and in the landscape. The authors' analysis of a statistically significant sample of Hittite temples - and a few monumental gates - has demonstrated that ancient Hittite monuments were not randomly orientated as previously thought. On the contrary, there were well-defined patterns of orientation that can be interpreted within the context of Hittite culture and religion.

  11. Preferential processing of cardinal over oblique orientations in human vision.

    Science.gov (United States)

    Westheimer, Gerald

    2017-11-01

    The oblique effect-poorer performance when contours are in oblique meridians-is here extended from the discrimination of line-orientation to the tilt illusion and to the detection and contextual induction of curvature. The distinction is made between a contour's susceptibility to contextual perturbation and its capacity to induce such perturbation, for which the oblique effect is only about one half. That the cardinal/oblique superiority is retained for the orientation of illusory borders and for the implicit orientation of shapes lacking explicit rectilinear delineation has implications for its neural substrate. To the extent that a geometrical-visual illusion, such as Poggendorff's or Hering's, depends on interaction in the domain of contour orientation, it manifests a corresponding orientational anisotropy. On the other hand, visual functions that govern whether and how well a boundary is visible are invariant with orientation.

  12. Contextual effects of scene on the visual perception of object orientation in depth.

    Directory of Open Access Journals (Sweden)

    Ryosuke Niimi

    Full Text Available We investigated the effect of background scene on the human visual perception of depth orientation (i.e., azimuth angle of three-dimensional common objects. Participants evaluated the depth orientation of objects. The objects were surrounded by scenes with an apparent axis of the global reference frame, such as a sidewalk scene. When a scene axis was slightly misaligned with the gaze line, object orientation perception was biased, as if the gaze line had been assimilated into the scene axis (Experiment 1. When the scene axis was slightly misaligned with the object, evaluated object orientation was biased, as if it had been assimilated into the scene axis (Experiment 2. This assimilation may be due to confusion between the orientation of the scene and object axes (Experiment 3. Thus, the global reference frame may influence object orientation perception when its orientation is similar to that of the gaze-line or object.

  15. Detection and segmentation of intersection and branch structures in medical images using orientation space

    International Nuclear Information System (INIS)

    Chen, Jian; Sato, Yoshinobu; Tamura, Shinichi

    1999-01-01

    The purpose of this paper is to present appropriate line segmentation for intersections (X-junctions) and branches (T-junctions). In the local regions of intersections and branches, multiple orientations occur. We propose a novel representation called the ''orientation space'', which is derived by adding the orientation axis to the abscissa and the ordinate of the image. The orientation space representation is constructed by treating the orientation parameter, to which Gabor filters can be tuned, as a continuous variable. The problem of multiple orientation line segmentation is dealt with by thresholding 3D images of the orientation space and then detecting the connected components therein. In this way, X-junctions and T-junctions can be separated effectively. Experimental results obtained using synthesized and real biomedical images are presented. In particular, overlapping vessels in an X-ray coronary angiogram were well segmented by orientation space filtering. (author)

  16. Age and Value Orientations

    2013-01-01

    Full Text Available The present article deals with value orientations and their role in men’s lives, particularly, in young people’s lives. This notion was introduced by the American theoretical sociologist T. Parsons, one of the creators of modern theoretical sociology. The scientist made an attempt to construct the structural and analytical theory of social action, combining personal interests (needs and aims and situation, it takes place in. The issue of value orientations remains acute for psychology. Herein we have considered several most important works, relating to the considered issue. Age aspects of young people’s value orientations are of peculiar interest to us. When analyzing this phenomenon, one should take into consideration the psychological formations, inhere for a certain age. In fact every age has its unique structure, which may change when passing from one development stage to another. Basing on this fact, we’ve considered the values, depending on the age features of the youth, relying upon the works of the scientists, working with different categories of the youth, such as: teenagers, students, children of different nationalities. It is not surprising that most scientists have come to the conclusion that the chief role in value orientation belongs to a family, originates in relations with parents and teachers. The positive reinforcement to the future develops throughout life in accordance with a lifestyle of a family, society and political situation in a state.Life orientations as a type of value orientations show different types of young people’s preferences. Value structure of its consciousness has its own specific character, depending on the age peculiarities. The dynamics of the transition from one age to another is accompanied with the reappraisal of values, eventually, influencing the life strategy of the future generation

    Geiss, Roy H.; Read, David T.; Alers, Glenn B.; Graham, Rebekah L.

    2009-09-01

    Orientation imaging microscopy by electron backscatter diffraction (EBSD) has been used to examine grain size and crystallographic orientations of damascene Cu lines nominally 25 nm to 55 nm in width and 100 nm thick. These are the smallest structures reported to have been examined by EBSD to date. This application poses significant challenges in specimen preparation, data collection, and data analysis. Most lines were deposited on a Ta diffusion barrier, and one set had a Ti barrier. Overburden thicknesses of 120 nm, 240 nm, and 480 nm were available with the Ta diffusion barrier, but only the 120 nm overburden case was analyzed for the Ti diffusion barrier. The grain structure of the lines was predominantly bamboo. The distributions of grain lengths along individual lines had large standard deviations, ranging up to greater than the average grain size value. Print-through of overburden grains into the grain structure of the lines was evident for all lines. Large grain sizes and a strong positive correlation between line width and grain size were seen for the case of the Ta barrier layer with 120 nm overburden thickness, but not for the thicker overburden cases. Specimen surface preparation of these lines was found to be much more demanding than for larger regions of copper films such as those that have been studied previously. For some lines, prepared according to the typical state of the art, we were able to find indexable diffraction signals from less than half of the 100 μm line length.

  1. Transgender transitioning and change of self-reported sexual orientation.

    Auer, Matthias K; Fuss, Johannes; Höhne, Nina; Stalla, Günter K; Sievers, Caroline

    2014-01-01

    Sexual orientation is usually considered to be determined in early life and stable in the course of adulthood. In contrast, some transgender individuals report a change in sexual orientation. A common reason for this phenomenon is not known. We included 115 transsexual persons (70 male-to-female "MtF" and 45 female-to-male "FtM") patients from our endocrine outpatient clinic, who completed a questionnaire, retrospectively evaluating the history of their gender transition phase. The questionnaire focused on sexual orientation and recalled time points of changes in sexual orientation in the context of transition. Participants were further asked to provide a personal concept for a potential change in sexual orientation. In total, 32.9% (n = 23) MtF reported a change in sexual orientation in contrast to 22.2% (n = 10) FtM transsexual persons (p = 0.132). Out of these patients, 39.1% (MtF) and 60% (FtM) reported a change in sexual orientation before having undergone any sex reassignment surgery. FtM that had initially been sexually oriented towards males ( = androphilic), were significantly more likely to report on a change in sexual orientation than gynephilic, analloerotic or bisexual FtM (p = 0.012). Similarly, gynephilic MtF reported a change in sexual orientation more frequently than androphilic, analloerotic or bisexual MtF transsexual persons (p =0.05). In line with earlier reports, we reveal that a change in self-reported sexual orientation is frequent and does not solely occur in the context of particular transition events. Transsexual persons that are attracted by individuals of the opposite biological sex are more likely to change sexual orientation. Qualitative reports suggest that the individual's biography, autogynephilic and autoandrophilic sexual arousal, confusion before and after transitioning, social and self-acceptance, as well as concept of sexual orientation itself may explain this phenomenon.

    1991-08-01

    The effect of a nonrandom source orientation on the angular diameter-redshift relation was considered for the 3CR sample of Laing et al., based on the 'unified' scheme of Barthel. For an inhomogeneous sample of objects displaying milliarcsecond scale structure, it was found that there was no evidence for a systematic variation for orientation angle with redshift. However, if it was assumed that quasars are closer to the line of sight than powerful extended radio galaxies, then the observed angular size-redshift relation could be interpreted in terms of source orientation, rather than linear size evolution.

  10. Value oriented strategic marketing

    Directory of Open Access Journals (Sweden)

    Milisavljević Momčilo

    2013-01-01

    Full Text Available Changes in today's business environment require companies to orient to strategic marketing. The company accepting strategic marketing has a proactive approach and focus on continuous review and reappraisal of existing and seeking new strategic business areas. Difficulties in achieving target profit and growth require turning marketing from the dominant viewpoint of the tangible product to creating superior value and developing relationships with customers. Value orientation implies gaining competitive advantage through continuous research and understanding of what value represents to the consumers and discovering new ways to meet their required values. Strategic marketing investment requires that the investment in the creation of values should be regularly reviewed in order to ensure a focus on customers with high profit potential and environmental value. This increases customer satisfaction and retention and long-term return on investment of companies.

  11. Electrodynamics and Time Orientability

    Science.gov (United States)

    Hadley, Mark J.

    2017-06-01

    On spacetimes that are not time orientable we construct a U(1) bundle to measure the twisting of the time axis. This single assumption, and simple construction, gives rise to Maxwell's equations of electromagnetism, the Lorentz force law and the Einstein-Maxwell equations for electromagnetism coupled to General relativity. The derivations follow the Kaluza Klein theory, but with the constraints required for connections on a U(1) bundle rather than five spacetime dimensions. The non time orientability is seen to justify and constrain Kaluza Klein theories exactly as required to unify gravitation with electromagnetism. Unlike any other schemes, apparent net electric charges arise naturally because the direction of the electric field reverses along a time reversing path. The boundary of a time reversing region can therefore have a net electric flux and appear exactly as a region containing an electric charge. The treatment is purely classical, but motivated by links between acausal structures and quantum theory.

    Today's enterprises are faced with highly dynamic, sometimes even hostile environments. This paper dicovers that the two most prominent organizational strategies addressing these challenges, namely that of widespread decentralization and of business process orientation, are inherently conflicting. We argue that cooperative knowledge processing technology can contribute to dissolve this conflict. For this purpose, we introduce the reader into the field of Distributed Artificial Intelligence.

    Computer science has experienced an evolution in programming languages and systems from the crude assembly and machine codes of the earliest computers through concepts such as formula translation, procedural programming, structured programming, functional programming, logic programming, and programming with abstract data types. Each of these steps in programming technology has advanced our ability to achieve clear separation of concerns at the source code level. Currently, the dominant programming paradigm is object-oriented programming - the idea that one builds a software system by decomposing a problem into objects and then writing the code of those objects. Such objects abstract together behavior and data into a single conceptual and physical entity. Object-orientation is reflected in the entire spectrum of current software development methodologies and tools - we have OO methodologies, analysis and design tools, and OO programming languages. Writing complex applications such as graphical user interfaces, operating systems, and distributed applications while maintaining comprehensible source code has been made possible with OOP. Success at developing simpler systems leads to aspirations for greater complexity. Object orientation is a clever idea, but has certain limitations. We are now seeing that many requirements do not decompose neatly into behavior centered on a single locus. Object technology has difficulty localizing concerns invoking global constraints and pandemic behaviors, appropriately segregating concerns, and applying domain-specific knowledge. Post-object programming (POP) mechanisms that look to increase the expressiveness of the OO paradigm are a fertile arena for current research. Examples of POP technologies include domain-specific languages, generative programming, generic programming, constraint languages, reflection and metaprogramming, feature-oriented development, views/viewpoints, and asynchronous message brokering.

  16. Recent Trends in Low-Temperature Nuclear Orientation and Nuclear Magnetic Resonance on Oriented Nuclei

    International Nuclear Information System (INIS)

    Chaplin, D. H.; Hutchison, W. D.

    2001-01-01

    Recent trends in Low-Temperature Nuclear Orientation (LTNO) and its site-selective derivative, Nuclear Magnetic Resonance on Oriented Nuclei (NMRON), are reviewed. Traditional areas of endeavour using elemental ferromagnetic hosts remain strong with significant improvements in methodology since last reviewed [1]; but there are new emphases emerging in solid-state physics and especially magnetism. Exotic single crystals hosts and MBE-grown multi-layers are gaining increased prominence as the principal focus of LTNO study. Increasingly, in off-line work and very recent on-line implantation into insulators [2], the radioactive probes are often chosen to be isoelectronic with an abundant chemical species within the host, rather than representing an extremely dilute, electronic impurity spy. Recent NMRON on a heavy rare earth, isoelectronic probe in an ordered rare earth halide opens up new dimensions.

    Since the magnetic field is responsible for most manifestations of solar activity, one of the most challenging problems in solar physics is the diagnostics of solar magnetic fields, particularly in the outer atmosphere. To this end, it is important to develop rigorous diagnostic tools to interpret polarimetric observations in suitable spectral lines. This paper is devoted to analyzing the diagnostic content of linear polarization imaging observations in coronal forbidden lines. Although this technique is restricted to off-limb observations, it represents a significant tool to diagnose the magnetic field structure in the solar corona, where the magnetic field is intrinsically weak and still poorly known. We adopt the quantum theory of polarized line formation developed in the framework of the density matrix formalism, and synthesize images of the emergent linear polarization signal in coronal forbidden lines using potential-field source-surface magnetic field models. The influence of electronic collisions, active regions, and Thomson scattering on the linear polarization of coronal forbidden lines is also examined. It is found that active regions and Thomson scattering are capable of conspicuously influencing the orientation of the linear polarization. These effects have to be carefully taken into account to increase the accuracy of the field diagnostics. We also found that linear polarization observation in suitable lines can give valuable information on the long-term evolution of the magnetic field in the solar corona.

    2006-01-01

    Full Text Available One the most fundamental aspects of the human motor system is the hemispheric asymmetry seen in behavioral specialization. Hemispheric dominance can be inferred by a contralateral hand preference in grasping. Few studies have considered grasp orientation in the context of manual lateralization and none has looked at grasp orientation with natural prehension. Thirty right-handed adults performed precision grasps of a cylinder using the thumb and index fingers, and the opposition axis (OA was defined as the line connecting these two contact points on the cylinder. Subjects made ten consecutive grasps with one hand (primary hand movements followed by ten grasps with the other hand (trailing movements. Differences between primary and trailing grasps revealed that each hemisphere is capable of programming the orientation of the OA and that primary movements with the right hand significantly influenced OA orientation of the trailing left hand. These results extend the hemispheric dominance of the left hemisphere to the final positions of fingers during prehension.

    Full Text Available In Belgrade the process of transition from oriental kasaba to European city was long and thwarted by various economic political and social cultural factors. The European ideal still hasn’t been reached. Transition, as a development process in Belgrade, operates by a specific paradoxical inversion – the logic of harmonised development of urban transport, urban form and structure, which in theories of urban planning appears as a postulate, is in Belgrade influenced by incredible, ephemeral, disfigured, yet authentic transformation. However, quality solutions, conclusions and recommendations for further implementation of the idea about introducing the new public transport system, which is part of the main project for the first light metro line in Belgrade, establishment of a united group of experts, investors, negotiators, public opinion and all actors needed to make decisions, united and uncompromising idea about the future image and quality of urban life in Belgrade, have uncovered an until recently untried field of possibilities for transport management coupled with urban development as the optimal and acceptable model. City life could again become dynamic, productive and attractive.

The humane-machine interaction systems are no longer solely fast and efficient. They aim to offer to users affective experiences: user's affective state is detected and considered within the interaction; the system displays affective state; it can reason about their implication to achieve a task or resolve a problem. In this book, we have chosen to cover various domains of research in emotion-oriented systems. Our aim

    In this article, I address the question of whether pedophilia in men can be construed as a male sexual orientation, and the implications for thinking of it in this way for scientific research, clinical practice, and public policy. I begin by defining pedophilia and sexual orientation, and then compare pedophilia (as a potential sexual orientation with regard to age) to sexual orientations with regard to gender (heterosexuality, bisexuality, and homosexuality), on the bases of age of onset, correlations with sexual and romantic behavior, and stability over time. I conclude with comments about the potential social and legal implications of conceptualizing pedophilia as a type of sexual orientation in males.

Since then it has generated outstanding events that have drawn guidelines in its history. These landmarks have taken place in different spheres of social, political and economic life. We have found that most workers and students from the University know less than fifty percent of such events, and we assume that the population outside the walls must have a greater ignorance. The present paper aims to spread these crucial events because knowing them will help appreciate better the real prestige of this house of higher learning through its rich  history, which will result in feelings of admiration and respect for this university.

  13. Fuel cycle oriented approach

    International Nuclear Information System (INIS)

    Petit, A.

    1987-01-01

    The term fuel cycle oriented approach is currently used to designate two quite different things: the attempt to consider all or part of a national fuel cycle as one material balance area (MBA) or to consider individual MBAs existing in a state while designing a unique safeguards approach for each and applying the principle of nondiscrimination to fuel cycles as a whole, rather than to individual facilities. The merits of such an approach are acceptability by the industry and comparison with the contemplated establishment of long-term criteria. The following points concern the acceptability by the industry: (1) The main interest of the industry is to keep an open international market and therefore, to have effective and efficient safeguards. (2) The main concerns of the industry regarding international safeguards are economic burden, intrusiveness, and discrimination. Answers to these legitimate concerns, which retain the benefits of a fuel cycle oriented approach, are needed. More specifically, the problem of reimbursing the operator the costs that he has incurred for the safeguards must be considered

    Full Text Available Craft education in Finland has been in a state of change. The concept of a holistic craft process was implemented in the National Core Curriculum in 2004 and the new Curriculum from 2014 strengthened it. Craft and holistic craft is not one unity but includes several orientations. This study aims to research student teachers’ conceptions and perceptions about diverse orientations and the necessity of craft education before they begin their studies in craft pedagogy. Given that the beliefs that student teachers bring to professional learning play a pivotal role in influencing what they can learn from teacher education, they are a subject worthy of investigation. The data consists of on‐line questionnaire answers by student teachers (N=113 at the University of Finland in teacher education in 2014. The on-line questionnaire was answered at the beginning of a basic course in textile craft education at an early stage of their teacher studies. Findings suggest that student teachers conceive of craft education primarily as model-oriented and skill-oriented rather than design-oriented and expression-oriented. Student teachers think that craft education is needed at school, but explanations are not very diverse. The findings of this study can be useful in the process of developing teacher education programmes.

    Full Text Available This paper proposes sustainable entrepreneurial orientation (SEO as a multidimensional construct that offers researchers the possibility of empirically testing their theoretical proposals in the sustainable entrepreneurship field. The authors propose an integration of different theories. In accordance with the dynamic capabilities view, SEO is approached under an organizational paradigm of strategic orientations delimited by competitive culture and multiple orientation perspectives. Furthermore, SEO’s nature is conceived at a firm-based entrepreneurship level and is based on an integrated triple bottom line sustainability. This approach is conceptualized using a categorization scheme and defined in accordance with the organizational predisposition perspective. Several research lines are proposed, all based on relational models with SEO as the key concept.

  19. Minimization over randomly selected lines

    Directory of Open Access Journals (Sweden)

    Ismet Sahin

    2013-07-01

    Full Text Available This paper presents a population-based evolutionary optimization method for minimizing a given cost function. The mutation operator of this method selects randomly oriented lines in the cost function domain, constructs quadratic functions interpolating the cost function at three different points over each line, and uses extrema of the quadratics as mutated points. The crossover operator modifies each mutated point based on components of two points in population, instead of one point as is usually performed in other evolutionary algorithms. The stopping criterion of this method depends on the number of almost degenerate quadratics. We demonstrate that the proposed method with these mutation and crossover operations achieves faster and more robust convergence than the well-known Differential Evolution and Particle Swarm algorithms.

    Full Text Available In order to establish rational pricing policy of renting sports facilities, should examine all relevant factors that influence the price. Market orientation, in determining the objectives of price policy, it must start from their basic goals of policy, such as: the needs of customers and profit. The main goal market orientation is the realization of such a profit that will allow continued expansion of sports facilities and continuously meet the needs of consumers at all higher levels. Pricing policy of renting sports facilities must be both profit-oriented, cost conscious, market-oriented and in line with any other goals you may have a sports agent. Pricing policies and procedures are related to each other and studied together. When we have got a policy objectives of renting sports facilities then we should choose the metod of determining price. Particular attention should be paid to the method of calculating costs. In this paper, we used methods og additional costs.

    2018-03-01

    Liquid crystalline cholesteric blue phases (BPs) continue to attract interest due to their fast response times and quasi-polarization-independent phase modulation capabilities. Various approaches have recently been proposed to control the crystal orientation of BPs on substrates; however, their basic orientation properties on standard, unidirectionally orienting alignment layers have not been investigated in detail. Through analysis of the azimuthal orientation of Kossel diagrams, we study the 3D crystal orientation of a BP material—with a phase sequence of cholesteric, BP I, and BP II—on unidirectionally orienting surfaces prepared using two methods: rubbing and photoalignment. BP II grown from the isotropic phase is sensitive to surface conditions, with different crystal planes orienting on the two substrates. On the other hand, strong thermal hysteresis is observed in BPs grown through a different liquid crystal phase, implying that the preceding structure determines the orientation. More specifically, the BP II–I transition is accompanied by a rotation of the crystal such that the crystal direction defined by certain low-value Miller indices transform into different directions, and within the allowed rotations, different azimuthal configurations are obtained in the same cell depending on the thermal process. Our findings demonstrate that, for the alignment control of BPs, the thermal process is as important as the properties of the alignment layer.

    2016-01-01

    An undirected graph G is locally irregular if every two of its adjacent vertices have distinct degrees. We say that G is decomposable into k locally irregular graphs if there exists a partition E1∪E2∪⋯∪Ek of the edge set E(G) such that each Ei induces a locally irregular graph. It was recently...... conjectured by Baudon et al. that every undirected graph admits a decomposition into at most three locally irregular graphs, except for a well-characterized set of indecomposable graphs. We herein consider an oriented version of this conjecture. Namely, can every oriented graph be decomposed into at most...... three locally irregular oriented graphs, i.e. whose adjacent vertices have distinct outdegrees? We start by supporting this conjecture by verifying it for several classes of oriented graphs. We then prove a weaker version of this conjecture. Namely, we prove that every oriented graph can be decomposed...

    This paper presents a registration method which based on straight lines primitive. Firstly, 2D straight lines are extracted from aerial images using Canny operator and straight line fitting. In the similar way, 3D straight lines are extracted from LiDAR range images which derive from laser scanning point cloud. Secondly, 3D straight lines are projected to aerial images using collinearity equations and Position and Orientation System (POS) data. Then the corresponding lines are determined by straight line error. At last, each image's new exterior orientation elements are calculated by generalized point (straight line) photogrammetry.

    Free-standing line patterns of Cu and Ni were manufactured by electrochemical deposition into lithographically prepared patterns. Electrodeposition was carried out on top of a highly oriented Au-layer physically vapor deposited on glass. Quantitative texture analysis carried out by means of x......-ray diffraction for both the substrate layer and the electrodeposits yielded experimental evidence for epitaxy between Cu and Au. An orientation relation between film and substrate was discussed with respect to various concepts of epitaxy. While the conventional mode of epitaxy fails for the Cu...

    Full Text Available The complexity of business environment imposes the need for continuous change and reexamination of business marketing strategies of enterprises. Theory and practice of strategic management and marketing show that the activities of marketing, which are closely connected to corporate strategy, are the key drivers of growth. There is a positive correlation between competition intensity, marketing strategy and business performance of companies. Even though, managers of many companies don't see a clear connection between marketing strategy and business performance, numerous empirical research show that the companies which possess and efficiently use marketing resources and capabilities are more successful. In knowledge-based economics, the development of value oriented marketing strategies for all participants in the chain is a supposition of the survival, growth and development of companies. Competitive advantage is the essence of any strategy. Acquisition and maintenance of competitive advantage is more successful if the potentials for value creation are used efficiently. The paper examines the critical factors that influence alignment and transformation of marketing strategies in accordance with changes in value estimation. Superior value, is created in different network classes. Theory and practice researches create a reliable basis for the development of new concepts, marketing strategy business models that will contribute to competitive advantage of enterprises and the economy.

    2014-01-01

    Objective Sexual orientation is usually considered to be determined in early life and stable in the course of adulthood. In contrast, some transgender individuals report a change in sexual orientation. A common reason for this phenomenon is not known. Methods We included 115 transsexual persons (70 male-to-female “MtF” and 45 female-to-male “FtM”) patients from our endocrine outpatient clinic, who completed a questionnaire, retrospectively evaluating the history of their gender transition phase. The questionnaire focused on sexual orientation and recalled time points of changes in sexual orientation in the context of transition. Participants were further asked to provide a personal concept for a potential change in sexual orientation. Results In total, 32.9% (n =  23) MtF reported a change in sexual orientation in contrast to 22.2% (n =  10) FtM transsexual persons (p =  0.132). Out of these patients, 39.1% (MtF) and 60% (FtM) reported a change in sexual orientation before having undergone any sex reassignment surgery. FtM that had initially been sexually oriented towards males ( = androphilic), were significantly more likely to report on a change in sexual orientation than gynephilic, analloerotic or bisexual FtM (p  =  0.012). Similarly, gynephilic MtF reported a change in sexual orientation more frequently than androphilic, analloerotic or bisexual MtF transsexual persons (p  =  0.05). Conclusion In line with earlier reports, we reveal that a change in self-reported sexual orientation is frequent and does not solely occur in the context of particular transition events. Transsexual persons that are attracted by individuals of the opposite biological sex are more likely to change sexual orientation. Qualitative reports suggest that the individual's biography, autogynephilic and autoandrophilic sexual arousal, confusion before and after transitioning, social and self-acceptance, as well as concept of sexual orientation itself may

  5. Religious orientation and life aspirations.

    2015-04-01

    The effects of religiosity on well-being appear to depend on religious orientation, with intrinsic orientation being related to positive outcomes and extrinsic orientation being related to neutral or negative outcomes. It is not clear, however, why intrinsic and extrinsic religiosity has the relationships they do. Self-determination theory may provide a useful framework of intrinsic and extrinsic aspirations that may help to answer this question. The purpose of the present study was to examine whether intrinsic and extrinsic religiosity would be related to intrinsic and extrinsic life aspirations. We hypothesized that intrinsic religiosity would be positively related to intrinsic life aspirations and negatively related with extrinsic life aspirations, and that extrinsic religiosity would be positively related to extrinsic life aspirations and negatively related to intrinsic aspirations, and that life aspirations would partially mediate the relationships between religious orientation and outcome. To study these hypotheses, a random national sample (total number of 425, average age of 52, 59 % female) completed the measures of religious orientation, life aspirations, affect, and life satisfaction. It was found that intrinsic religiosity was positively related to positive affect, life satisfaction, and intrinsic life aspirations and was negatively related to negative affect and extrinsic life aspirations. Extrinsic religiosity was positively related to extrinsic life aspirations and was not related to the intrinsic life aspirations. When both religious orientation and life aspiration variables were included together in the model predicting outcome, both remained significant indicating that religious orientation and life aspirations are independent predictors of outcome. In conclusion, although religious orientation and life aspirations are significantly related to each other and to outcome, life aspirations did not mediate the effects of religious orientation

The analysis of the literature on the programming and the modern school textbook on informatics, and also theoretical material on object-oriented programming within the informative line “Algorithmization and programming” of school course of informatics is for this purpose carried out. The object-oriented approached essentially differs from structured programming in fact that the object-oriented programming paradigm is more open and scalable. It doesn’t mean that transition to the object-oriented approach to programming demands a failure from all algorithm applied in case of structural pro-applications of all earlier found and tested method and receptions. On the contrary new elements are always based on prior experience. Object approach creates a set of essential convenience which under other conditions can’t provide.

    To better understand sexual orientation from an evolutionary perspective, we investigated whether, compared to heterosexual men, the fewer direct descendants of homosexual men could be counterbalanced by a larger number of other close biological relatives. We also investigated the extent to which three patterns generally studied separately--handedness, number of biological older brothers, and hair-whorl rotation pattern--correlated with each other, and for evidence of replication of previous findings on how each pattern related to sexual orientation. We surveyed at Gay Pride and general community festivals, analyzing data for 894 heterosexual men and 694 homosexual men, both groups predominantly (~80%) white/non-Hispanic. The Kinsey distribution of sexual orientation for men recruited from the general community festivals approximated previous population-based surveys. Compared to heterosexual men, homosexual men had both more relatives, especially paternal relatives, and more homosexual male relatives. We found that the familiality for male sexual orientation decreased with relatedness, i.e., when moving from first-degree to second-degree relatives. We also replicated the fraternal birth order effect. However, we found no significant correlations among handedness, hair whorl rotation pattern, and sexual orientation, and, contrary to some previous research, no evidence that male sexual orientation is transmitted predominantly through the maternal line.

  9. Oriented active shape models.

    Liu, Jiamin; Udupa, Jayaram K

    2009-04-01

    Active shape models (ASM) are widely employed for recognizing anatomic structures and for delineating them in medical images. In this paper, a novel strategy called oriented active shape models (OASM) is presented in an attempt to overcome the following five limitations of ASM: 1) lower delineation accuracy, 2) the requirement of a large number of landmarks, 3) sensitivity to search range, 4) sensitivity to initialization, and 5) inability to fully exploit the specific information present in the given image to be segmented. OASM effectively combines the rich statistical shape information embodied in ASM with the boundary orientedness property and the globally optimal delineation capability of the live wire methodology of boundary segmentation. The latter characteristics allow live wire to effectively separate an object boundary from other nonobject boundaries with similar properties especially when they come very close in the image domain. The approach leads to a two-level dynamic programming method, wherein the first level corresponds to boundary recognition and the second level corresponds to boundary delineation, and to an effective automatic initialization method. The method outputs a globally optimal boundary that agrees with the shape model if the recognition step is successful in bringing the model close to the boundary in the image. Extensive evaluation experiments have been conducted by utilizing 40 image (magnetic resonance and computed tomography) data sets in each of five different application areas for segmenting breast, liver, bones of the foot, and cervical vertebrae of the spine. Comparisons are made between OASM and ASM based on precision, accuracy, and efficiency of segmentation. Accuracy is assessed using both region-based false positive and false negative measures and boundary-based distance measures. The results indicate the following: 1) The accuracy of segmentation via OASM is considerably better than that of ASM; 2) The number of landmarks

    Aull, Felice; Lewis, Bradley

    2004-01-01

    In this paper, we propose analogies between medical discourse and Edward Said's "Orientalism." Medical discourse, like Orientalism, tends to favor institutional interests and can be similarly dehumanizing in its reductionism, textual representations, and construction of its subjects. To resist Orientalism, Said recommends that critics--"intellectuals"--adopt the perspective of exile. We apply Said's paradigm of intellectual-as-exile to better understand the work of key physician-authors who cross personal and professional boundaries, who engage with patients in mutually therapeutic relationships, and who take on the public responsibility of representation and advocacy. We call these physician-authors "medical intellectuals" and encourage others to follow in their path.

    Objective. Target selectivity of deep brain stimulation (DBS) therapy is critical, as the precise locus and pattern of the stimulation dictates the degree to which desired treatment responses are achieved and adverse side effects are avoided. There is a clear clinical need to improve DBS technology beyond currently available stimulation steering and shaping approaches. We introduce orientation selective neural stimulation as a concept to increase the specificity of target selection in DBS. Approach. This concept, which involves orienting the electric field along an axonal pathway, was tested in the corpus callosum of the rat brain by freely controlling the direction of the electric field on a plane using a three-electrode bundle, and monitoring the response of the neurons using functional magnetic resonance imaging (fMRI). Computational models were developed to further analyze axonal excitability for varied electric field orientation. Main results. Our results demonstrated that the strongest fMRI response was observed when the electric field was oriented parallel to the axons, while almost no response was detected with the perpendicular orientation of the electric field relative to the primary fiber tract. These results were confirmed by computational models of the experimental paradigm quantifying the activation of radially distributed axons while varying the primary direction of the electric field. Significance. The described strategies identify a new course for selective neuromodulation paradigms in DBS based on axonal fiber orientation.

    2012-11-01

    Task-oriented training is emerging as the dominant and most effective approach to motor rehabilitation of upper extremity function after stroke. Here, the authors propose that the task-oriented training framework provides an evidence-based blueprint for the design of task-oriented robots for the rehabilitation of upper extremity function in the form of three design principles: skill acquisition of functional tasks, active participation training, and individualized adaptive training. The previous robotic systems that incorporate elements of task-oriented trainings are then reviewed. Finally, the authors critically analyze their own attempt to design and test the feasibility of a TOR robot, ADAPT (Adaptive and Automatic Presentation of Tasks), which incorporates the three design principles. Because of its task-oriented training-based design, ADAPT departs from most other current rehabilitation robotic systems: it presents realistic functional tasks in which the task goal is constantly adapted, so that the individual actively performs doable but challenging tasks without physical assistance. To maximize efficacy for a large clinical population, the authors propose that future task-oriented robots need to incorporate yet-to-be developed adaptive task presentation algorithms that emphasize acquisition of fine motor coordination skills while minimizing compensatory movements.

  20. Long range position and Orientation Tracking System

    Energy Technology Data Exchange (ETDEWEB)

    Armstrong, G.A.; Jansen, J.F.; Burks, B.L. [and others

    1996-02-01

    The long range Position and Orientation Tracking System is an active triangulation-based system that is being developed to track a target to a resolution of 6.35 mm (0.25 in.) and 0.009{degrees}(32.4 arcseconds) over a range of 13.72 m (45 ft.). The system update rate is currently set at 20 Hz but can be increased to 100 Hz or more. The tracking is accomplished by sweeping two pairs of orthogonal line lasers over infrared (IR) sensors spaced with known geometry with respect to one another on the target (the target being a rigid body attached to either a remote vehicle or a remote manipulator arm). The synchronization and data acquisition electronics correlates the time that an IR sensor has been hit by one of the four lasers and the angle of the respective mirror at the time of the hit. This information is combined with the known geometry of the IR sensors on the target to determine position and orientation of the target. This method has the advantage of allowing the target to be momentarily lost due to occlusions and then reacquired without having to return the target to a known reference point. The system also contains a camera with operator controlled lighting in each pod that allows the target to be continuously viewed from either pod, assuming their are no occlusions.

    The nature of the glass transition, the transformation of a liquid into a disordered solid, still remains one of the most intriguing unsolved problems in materials science. Recent models rationalize crucial features of vitrification with the presence of medium-range ordered regions coexisting with the isotropic liquid. In lines with this prediction, here we report an extraordinary enhancement in bond orientational order (BOO) in ultrathin films of supercooled polyols, grown by physical vapour deposition. By varying the deposition conditions and the molecular size, we could tune the kinetic stability of the liquid phase enriched in BOO towards conversion into the ordinary liquid phase. We observed a strong increase in the dielectric strength with respect to the ordinary supercooled liquid and slower structural dynamics, suggesting the existence of a metastable liquid phase with improved orientational correlations.

  2. Surface structure of oriented PET films

    CERN Document Server

    Kirov, K

    2001-01-01

    crystallinity and the level of molecular orientation of the polymer are highest at the film surface and gradually decrease away from it. The same trend for an increase in structural order nearer the film surface was observed in a series of PET films drawn uniaxially in laboratory conditions. The observed strong dependence of stratification in the oriented films on drawing ratio, lead to the conclusion, that the structural gradients arise as a result of viscous flow. The molecular mechanism of stratification is discussed and leads to the idea of enhanced chain mobility at the PET film surface. The idea is in line with recent studies showing a depression of the glass transition temperature of free polymer surfaces. In addition, the results on structure formation in PET films during drawing, give support to the existing view that polymer crystallisation is assisted by a spinodal-decomposition nucleation process. Polymer films are widely used as substrates in nano-composite materials and therefore have to possess...

    Kelly, Shane P; Brockmole, James R

    2014-01-01

    Observers determined whether two sequentially presented arrays of six lines were the same or different. Differences, when present, involved either a swap in the color of two lines or a swap in the orientation of two lines. Thus, accurate change detection required the binding of color and orientation information for each line within visual working memory. Holding viewing distance constant, the proximity of the arrays to the hands was manipulated. Placing the hands near the to-be-remembered array decreased participants' ability to remember color information, but increased their ability to remember orientation information. This pair of results indicates that hand proximity differentially affects the processing of various types of visual information, a conclusion broadly consistent with functional and anatomical differences in the magnocellular and parvocellular pathways. It further indicates that hand proximity affects the likelihood that various object features will be encoded into integrated object files.

    2012-02-01

    The self-reports of individuals who claim that they have changed their sexual orientation are either dismissed as false or relied upon to promote sexual orientation change efforts. However, these reactions do not capture the complexity of the sexual reorientation phenomenon. This article provides an overview regarding the promise and effort of sexual reorientation and how this knowledge may inform our current understanding of human sexuality. Specifically, a brief history is given of the interventions used to change attractions to same-sex adults and the assumptions underlying these efforts. Information will be given regarding which conclusions can be derived from sexual reorientation studies. The limitations of these studies will be explained to strengthen future research. Hypotheses will be presented regarding the motivations and needs of those distressed by a same-sex erotic orientation and the impact that the hope of sexual reorientation may have for family members, religious leaders, and policy makers. A multivariate model of sexuality and sexual orientation, including scales of attraction and aversion, will be proposed based upon current understanding of sexuality and the distinctions found in sexual reorientation research. In the end, a therapeutic framework will be highlighted that may be used (and researched) to help those distressed by their sexual orientation.

    Full Text Available Consistent with the extant management literature, mission statements are crucial for the sustainability and growth of any firms and have been considered to be a tool for the strategic management process. Despite the considerable attention awarded to this theme, the role of the mission statement in the strategic management of tourism firms has not been sufficiently highlighted. The present paper tries to bridge this literature gap and aims to (i analyze the content of mission statements; and (ii investigate the stakeholder orientation of cruise line mission statements. We apply a content analysis method to analyze the mission statements of 44 cruise lines, employing three different perspectives: (1 the inclusion of stakeholder groups; (2 mentions of specific “mission” components; (3 reference to four goals usually assigned to mission statements. The analysis was performed using the software package QDA-Miner. The results suggest that it is possible to identify four clusters of firms that present similar content in their mission statements, and that cruise companies tend to reserve a major attention to customers. This contribution presents some valuable research implications mainly useful for researchers and academics, but also maybe of benefit to professionals and investors.

  11. A cardinal orientation bias in scene-selective visual cortex.

    Nasr, Shahin; Tootell, Roger B H

    2012-10-24

    It has long been known that human vision is more sensitive to contours at cardinal (horizontal and vertical) orientations, compared with oblique orientations; this is the "oblique effect." However, the real-world relevance of the oblique effect is not well understood. Experiments here suggest that this effect is linked to scene perception, via a common bias in the image statistics of scenes. This statistical bias for cardinal orientations is found in many "carpentered environments" such as buildings and indoor scenes, and some natural scenes. In Experiment 1, we confirmed the presence of a perceptual oblique effect in a specific set of scene stimuli. Using those scenes, we found that a well known "scene-selective" visual cortical area (the parahippocampal place area; PPA) showed distinctively higher functional magnetic resonance imaging (fMRI) activity to cardinal versus oblique orientations. This fMRI-based oblique effect was not observed in other cortical areas (including scene-selective areas transverse occipital sulcus and retrosplenial cortex), although all three scene-selective areas showed the expected inversion effect to scenes. Experiments 2 and 3 tested for an analogous selectivity for cardinal orientations using computer-generated arrays of simple squares and line segments, respectively. The results confirmed the preference for cardinal orientations in PPA, thus demonstrating that the oblique effect can also be produced in PPA by simple geometrical images, with statistics similar to those in scenes. Thus, PPA shows distinctive fMRI selectivity for cardinal orientations across a broad range of stimuli, which may reflect a perceptual oblique effect.

    As organizations seek to better understand their customers, competitors, and environments, the marketing function effectively serves as the support mechanism for these activities in many industries. Accordingly, in many organizations the marketing concept has been elevated to the stature of a strategic weapon, manifested in the form of market orientation. Market-oriented firms emphasize the collection, organization, and dissemination of information regarding both customers and competitors. This strategy is especially well-suited for the health care industry where customer knowledge is of paramount importance, customer interaction is instantaneous, and customer satisfaction is essential. Results of a national study of general service hospitals suggest that firms which embrace a market orientation benefit through enhanced customer satisfaction and quality.

    Azobenzene molecules and their derivatives have been widely investigated for their potential applications in optical and electrooptical devices. We have prepared a new guest-host system from natural rubber (NR) impregnated with azobenzene derivative Sudan Red B (SRB). The effects of stretching and immersion time on photoinduced orientation were investigated by birefringence signal measurements. We have found that the molecular orientation increase when the samples are stretched and decrease with the increase of immersion time. The first behavior was explained by using the random coil model and the latter was attributed to increase of the aggregation of SRB into NR matrix.

When it is used correctly, it promises to remove many redundant parts of a code that appear repeatedly in an application, essentially untangling the original code. Thus, it can lead to a cleaner, more separated software design, to greater modularity and maintainability. Time-savings in software engineering can also be huge cost-savings, and anything that increases software quality is a welcome sight in an industr

    Full Text Available Orientation plays a vital role for organizations to compete to create sustainable competitive advantage. The objective of this study is to examine the relationship between market orientation (MO and organizational performance (OP with service quality (SQ as a moderator in the context of the hotel industry in Malaysia. MO and OP were conceptualized as three- and two-dimensional constructs, respectively, whereas SQ, which consists of two-dimensional constructs, namely, technical quality and functional quality, was used as a moderator. Data were gathered through a survey using a structured questionnaire with a sample of 187 executive-level employees employed in hotels rated three stars and above in Malaysia. SmartPLS 2.0 (M3 with path modeling and bootstrapping was used to examine the standard error of the estimate and t-values. The findings suggest that only competitor orientation dimension of MO was significantly related to OP, whereas customer orientation and inter-functional coordination were not related. Interestingly, SQ was found to have moderated the relationship between MO and performance of the hotels in Malaysia. SQ exists to fill in the gap between customers’ expectations and their perception of the service providers’ performance that further creates differentiation and competitive advantage, which enhance MO practices and ultimately lead to improvements in the firm’s performance. Implications of the findings, potential limitations of the study, and directions for future research are highlighted.

  17. Object-Oriented Heterogeneous Database for Materials Science

    Directory of Open Access Journals (Sweden)

    David Hansen

    1992-01-01

    Full Text Available As a part of the scientific database research underway at the Oregon Graduate Institute, we are collaborating with materials scientists in the research and development of an extensible modeling and computation environment for materials science. Materials scientists are prolific users of computers for scientific research. Modeling techniques and algorithms are well known and refined, and computerized databases of chemical and physical property data abound. However, applications are typically developed in isolation, using information models specifically tailored for the needs of each application. Furthermore, available computerized databases in the form of CDs and on-line information services are still accessed manually by the scientist in an off-line fashion. Thus researchers are repeatedly constructing and populating new custom databases for each application. The goal of our research is to bridge this gulf between applications and sources of data. We believe that object-oriented technology in general and data-bases in particular, provide powerful tools for transparently bridging the gap between programs and data. An object-oriented database that not only manages data generated by user applications, but also provides access to relevant external data sources can be used to bridge this gap. An object-oriented database for materials science data is described that brings together data from heterogeneous non-object-oriented sources and formats, and presents the user with a single, uniform object-oriented schema that transparently integrates these diverse databases. A unique multilevel architecture is presented that provides a mechanism for efficiently accessing both heterogeneous external data sources and new data stored within the database.

  1. Artificial web of disclination lines in nematic liquid crystals.

    Science.gov (United States)

    Wang, Mengfei; Li, Yannian; Yokoyama, Hiroshi

    2017-08-30

    Disclinations are topological singularities of molecular arrangement in liquid crystals, which typically occur when the average orientation of molecules makes a π rotation along a fictitious closed loop taken inside the liquid crystal. Depending on the sense of molecular rotation, the disclination lines are either of 1/2 or -1/2 strength. When two disclination lines with the opposite strength meet, they are annihilated without trace. It is hence generally considered difficult in the nematic phase to stabilize a condensed array of free-standing disclination lines without the aid of topological objects like colloidal inclusions. Here we show that a free-standing web of 1/2-strength twist disclination lines can be stably formed in thin liquid crystal cells by means of a judicious combination of orientationally patterned confining surfaces fabricated by the micropatterned photoalignment technique. Theoretical model indicates that disclination lines are held apart at the intersection by a repulsive force generated by the Frank elasticity.Disclination lines are topological defects in molecular orientation widely found in liquid crystals. Here Wang et al. use a surface patterning technique to produce a very stable freestanding 3D array of ½ twist disclinations, which could be exploited in a variety of nanometre scale applications.

    Full Text Available Oriented collagen scaffolds were developed in the form of sheet, mesh and tube by arraying flow-oriented collagen string gels and dehydrating the arrayed gels. The developed collagen scaffolds can be any practical size with any direction of orientation for tissue engineering applications. The birefringence of the collagen scaffolds was quantitatively analyzed by parallel Nicols method. Since native collagen in the human body has orientations such as bone, cartilage, tendon and cornea, and the orientation has a special role for the function of human organs, the developed various types of three-dimensional oriented collagen scaffolds are expected to be useful biomaterials for tissue engineering and regenerative medicines.

  4. Covariant electromagnetic field lines

    Faraday introduced electric field lines as a powerful tool for understanding the electric force, and these field lines are still used today in classrooms and textbooks teaching the basics of electromagnetism within the electrostatic limit. However, despite attempts at generalizing this concept beyond the electrostatic limit, such a fully relativistic field line theory still appears to be missing. In this work, we propose such a theory and define covariant electromagnetic field lines that naturally extend electric field lines to relativistic systems and general electromagnetic fields. We derive a closed-form formula for the field lines curvature in the vicinity of a charge, and show that it is related to the world line of the charge. This demonstrates how the kinematics of a charge can be derived from the geometry of the electromagnetic field lines. Such a theory may also provide new tools in modeling and analyzing electromagnetic phenomena, and may entail new insights regarding long-standing problems such as radiation-reaction and self-force. In particular, the electromagnetic field lines curvature has the attractive property of being non-singular everywhere, thus eliminating all self-field singularities without using renormalization techniques.

  5. The Widom line of supercooled water

    2007-01-01

    Water can be supercooled to temperatures as low as -92 deg. C, the experimental crystal homogeneous nucleation temperature T H at 2 kbar. Within the supercooled liquid phase its response functions show an anomalous increase consistent with the presence of a liquid-liquid critical point located in a region inaccessible to experiments on bulk water. Recent experiments on the dynamics of confined water show that a possible way to understand the properties of water is to investigate the supercooled phase diagram in the vicinity of the Widom line (locus of maximum correlation length) that emanates from the hypothesized liquid-liquid critical point. Here we explore the Widom line for a Hamiltonian model of water using an analytic approach, and discuss the plausibility of the hypothesized liquid-liquid critical point, as well as its possible consequences, on the basis of the assumptions of the model. The present analysis allows us (i) to find an analytic expression for the spinodal line of the high-density liquid phase, with respect to the low-density liquid phase, showing that this line becomes flat in the P-T phase diagram in the physical limit of a large number of available orientations for the hydrogen bonds, as recently seen in simulations and experiments (Xu et al 2005 Proc. Natl Acad. Sci. 102 16558); (ii) to find an estimate of the values for the hypothesized liquid-liquid critical point coordinates that compare very well with Monte Carlo results; and (iii) to show how the Widom line can be located by studying the derivative of the probability of forming hydrogen bonds with local tetrahedral orientation which can be calculated analytically within this approach

    First and second chambers, each having a rotor, are interconnected by a passage. The first chamber has a contoured periphery to receive articles and the passage is shaped and dimensioned to permit travel therealong only of those articles which are orientated in the first chamber with their longitudinal axes either in the direction of travel or normal to the direction of travel. Articles in other orientations are carried round the first chamber by the rotor for representation at the passage. The rotor in the second chamber permits the passage of those articles which have their longitudinal axes in the direction of travel and topples by means of blades, the articles having their axes normal to the direction of travel into positions in which the axes are in the direction of travel.

    Full Text Available This dossier contains a series of articles inspired by Edward Said's concept of Orientalism. Together, the articles in the dossier show the importance of Said's contribution and defend the need to continue working to make it even more important and valid, both in the academic context and in terms of the social diffusion it deserves. With a common thematic thread -the perception of the other (Orient from our perspective (Occident- these articles shun the conception of East Asia as an independent "discipline" and treat it, on the contrary, as an object of study that must be tackled with methodological rigour from specific disciplines: history, thought, anthropology and literature. This should facilitate, on one hand, the possibility of putting forward arguments and observations that enrich already existing debates in each discipline by shedding new light on them and, on the other, social diffusion of these ideas on East Asia beyond limited circles.

    CERN Multimedia

    2000-01-01

    Object oriented technologies are the corner stone of modern software development. A piece of software is today conceived, constructed and tested as a set of objects interacting with each other, rather than as a large sequential program. OO is present throughout the whole software life cycle allowing for maintainable code re-use, clean design and manageable complexity. OO is also the seed upon which other technologies are being built and deployed, such as distributed computing, component models, open interoperability, etc.This series of three seminars will provide a pragmatic overview on the main ideas behind OO software development and will explain the inner workings of the most outstanding technologies being built on OO, such as UML, CORBA, Component Models, Agent Oriented Computing, Business Objects, etc.

    2017-09-01

    Probable stimuli are more often and more quickly detected. While stimulus probability is known to affect decision-making, it can also be explained as a perceptual phenomenon. Using spatial gratings, we have previously shown that probable orientations are also more precisely estimated, even while participants remained naive to the manipulation. We conducted an electrophysiological study to investigate the effect that probability has on perception and visual-evoked potentials. In line with previous studies on oddballs and stimulus prevalence, low-probability orientations were associated with a greater late positive 'P300' component which might be related to either surprise or decision-making. However, the early 'C1' component, thought to reflect V1 processing, was dampened for high-probability orientations while later P1 and N1 components were unaffected. Exploratory analyses revealed a participant-level correlation between C1 and P300 amplitudes, suggesting a link between perceptual processing and decision-making. We discuss how these probability effects could be indicative of sharpening of neurons preferring the probable orientations, due either to perceptual learning, or to feature-based attention.

  16. A resource oriented webs service for environmental modeling

    Science.gov (United States)

    Ferencik, Ioan

    2013-04-01

    Environmental modeling is a largely adopted practice in the study of natural phenomena. Environmental models can be difficult to build and use and thus sharing them within the community is an important aspect. The most common approach to share a model is to expose it as a web service. In practice the interaction with this web service is cumbersome due to lack of standardized contract and the complexity of the model being exposed. In this work we investigate the use of a resource oriented approach in exposing environmental models as web services. We view a model as a layered resource build atop the object concept from Object Oriented Programming, augmented with persistence capabilities provided by an embedded object database to keep track of its state and implementing the four basic principles of resource oriented architectures: addressability, statelessness, representation and uniform interface. For implementation we use exclusively open source software: Django framework, dyBase object oriented database and Python programming language. We developed a generic framework of resources structured into a hierarchy of types and consequently extended this typology with recurses specific to the domain of environmental modeling. To test our web service we used cURL, a robust command-line based web client.

    2016-09-01

    SummaryOngoing political controversies around the world exemplify a long-standing and widespread preoccupation with the acceptability of homosexuality. Nonheterosexual people have seen dramatic surges both in their rights and in positive public opinion in many Western countries. In contrast, in much of Africa, the Middle East, the Caribbean, Oceania, and parts of Asia, homosexual behavior remains illegal and severely punishable, with some countries retaining the death penalty for it. Political controversies about sexual orientation have often overlapped with scientific controversies. That is, participants on both sides of the sociopolitical debates have tended to believe that scientific findings-and scientific truths-about sexual orientation matter a great deal in making political decisions. The most contentious scientific issues have concerned the causes of sexual orientation-that is, why are some people heterosexual, others bisexual, and others homosexual? The actual relevance of these issues to social, political, and ethical decisions is often poorly justified, however. © The Author(s) 2016.

    Due to developments of the health market, economic aspects of the health system are more relevant. In this upcoming market the patient is regarded as customer and the doctor as provider of medical services. Studies on customer orientation in the ambulant medicine lag behind this dynamic. An aim of the study is to comprehend the attitudes of the doctors referring to the customer orientation. In a second step the findings are discussed according to statements of health-care paticipants. Developments in role comprehension of doctor and patient are focused to gain results in scientific and practical applications. Guideline-supported, partly narrative interviews with n=9 gynaecologists and n=11 general practitioners in Freiburg/Germany are recorded, transcribed and reviewed in a qualitative analysis. The statements of the doctors show patient satisfaction has an incremental meaning sspecially regarding the sequence of patient relationship and economic management of the doctor's workplace. The doctor's role comprehension meets with a refusal of the role of salesman and the patient as customer. The method of interviews is suitable to gather empirical impressions of the doctors. The control sample is adequate, however a bias due to inhomogeneous thematic affinitiy and local social-demographics might be possible. The customer orientation has become an important factor in doctor-patient relationtships. The relevance of the doctor-patient conversation and the risk of misuse of the patient confidence are mentioned by the doctors. The doctor as paternalistic care provider gives way to the customer-focused service provider. The doctor's necessity of autonomyssss and dependency on patient satisfaction have potential for conflict. Intensive mention of customer orientation in medicine in the media emphasises its importance. Rational handling with the possibilities of individual health markets is a prospective challange. Further research could be established in all aspects of

  6. Statistical Study of the Magnetic Field Orientation in Solar Filaments

    2017-12-01

    We have carried out a statistical study of the average orientation of the magnetic field in solar filaments with respect to their axes for more than 400 samples, based on data taken with daily full-Sun, full-Stokes spectropolarimetric observations using the He I 1083.0 nm line. The major part of the samples are the filaments in the quiet areas, but those in the active areas are included as well. The average orientation of the magnetic field in filaments shows a systematic property depending on the hemisphere; the direction of the magnetic field in filaments in the northern (southern) hemisphere mostly deviates clockwise (counterclockwise) from their axes, which run along the magnetic polarity inversion line. The deviation angles of the magnetic field from the axes are concentrated between 10° and 30°. This hemispheric pattern is consistent with that revealed for chirality of filament barbs, filament channels, and for other solar features found to possess chirality. For some filaments, it was confirmed that their magnetic field direction is locally parallel to their structure seen in Hα images. Our results for the first time confirmed this hemispheric pattern with the direct observation of the magnetic field in filaments. Interestingly, the filaments which show the opposite magnetic field deviation to the hemispheric pattern, are in many cases found above the polarity inversion line whose ambient photospheric magnetic field has the polarity alignment being opposite to that of active regions following the Hale–Nicholson law.

    Full Text Available Published literature about moving objects (MO simplifies the problem to the representation and storage of moving points, moving lines, or moving regions. The main insufficiency of this approach is lack of MO inner structure and dynamics modeling – the autonomy of moving agent. This paper describes basics of the object-oriented geospatial methodology for modeling complex systems consisting of agents, which move within spatial environment. The main idea is that during the agent movement, different kinds of connections with other moving or stationary objects are established or disposed, based on some spatial constraint satisfaction or nonfulfilment respectively. The methodology is constructed with regard to following two main conditions – 1 the inner behavior of agents should be represented by any formalism, e.g.  Petri net, finite state machine, etc., and 2 the spatial characteristic of environment should be supplied by any information system, that is able to store defined set of spatial types, and support defined set of spatial operations. Finally, the methodology is demonstrated on simple simulation model of tram transportation system.

    2002-07-01

    Cultured cell lines have become an extremely valuable resource, both in academic research and in industrial biotechnology. However, their value is frequently compromised by misidentification and undetected microbial contamination. As detailed elsewhere in this volume, the technology, both simple and sophisticated, is available to remedy the problems of misidentification and contamination, given the will to apply it. Combined with proper records of the origin and history of the cell line, assays for authentication and contamination contribute to the provenance of the cell line. Detailed records should start from the initiation or receipt of the cell line, and should incorporate data on the donor as well as the tissue from which the cell line was derived, should continue with details of maintenance, and include any accidental as well as deliberate deviations from normal maintenance. Records should also contain details of authentication and regular checks for contamination. With this information, preferably stored in a database, and suitable backed up, the provenance of the cell line so created makes the cell line a much more valuable resource, fit for validation in industrial applications and more likely to provide reproducible experimental results when disseminated for research in other laboratories.

    Galindo-Cardona, A; Monmany, A C; Diaz, G; Giray, T

    2015-08-01

    Honey bees [Apis mellifera L. (Apidae, Hymenoptera)] show spatial learning behavior or orientation, in which animals make use of structured home ranges for their daily activities. Worker (female) orientation has been studied more extensively than drone (male) orientation. Given the extensive and large flight range of drones as part of their reproductive biology, the study of drone orientation may provide new insight on landscape features important for orientation. We report the return rate and orientation of drones released at three distances (1, 2, and 4 km) and at the four cardinal points from an apiary located in Gurabo, Puerto Rico. We used high-resolution aerial photographs to describe landscape characteristics at the releasing sites and at the apiary. Analyses of variance were used to test significance among returning times from different distances and directions. A principal components analysis was used to describe the landscape at the releasing sites and generalized linear models were used to identify landscape characteristics that influenced the returning times of drones. Our results showed for the first time that drones are able to return from as far as 4 km from the colony. Distance to drone congregation area, orientation, and tree lines were the most important landscape characteristics influencing drone return rate. We discuss the role of landscape in drone orientation. © The Authors 2015. Published by Oxford University Press on behalf of Entomological Society of America. All rights reserved.

    2017-04-01

    We asked whether "good composition" or "visual rightness" of artworks manifest themselves in a particular arrangement of basic image features, such as oriented luminance edges. Specifically, we analysed the layout of edge orientations in images from a collection of >1600 paintings of Western provenance by comparing pairwise the orientation of each edge in an image with the orientations of all other edges in the same image. From the resulting orientation histograms, we calculated Shannon entropy and parallelism (i.e., the degree to which lines are parallel in the image). For comparison, we analysed the same second-order image properties in photographs of diverse natural patterns and man-made objects and scenes. Results showed that Shannon entropy of relative orientations of edge pairs was high and parallelism was low for the paintings and some of the natural patterns, but differed from other sets of photographs, including other man-made stimuli. The differences were also observed when images were matched for image content. Moreover, high entropy of edge orientations was found in traditional artworks produced by different techniques, in artworks that represented different content matter and art genres, as well as in artworks from other cultural backgrounds (East Asian and Islamic). In conclusion, we found that high entropy of edge orientations characterizes diverse sets of traditional artworks from various cultural backgrounds. Copyright © 2017 Elsevier Ltd.

    Factors associated with students' orientations to nursing This paper presents the results of a study focusing on the factors associated with orientations to nursing. Students' orientations to nursing have not as yet been a focus of nursing research. In some other professions, however, professional orientation has been associated with learning motivation and study performance, and has been seen as a predictor of work satisfaction. In this study, students' orientations to nursing were defined in terms of caring, nursing expertise and life orientation. The hypothesis of whether students' pre-educational experiences of nursing, gender, choice of nursing specialty, problems with nursing studies and intention to stay in nursing were associated with different orientations was tested. The extent to which students were orientated to caring, nursing expertise and their own life was also examined. The orientation to nursing measurement tool, which has been developed on the basis of a qualitative study, was used to collect the data. Nurse teachers collected the data from nursing students (n=184) who were studying in three different nursing programmes in Finland. Non-parametric assessments (Mann-Whitney U-test and Kruskal-Wallis test) of the differences between the students' orientations were carried out. A majority of the students were highly life-orientated, and two-thirds had average nursing expertise or caring orientation scores. The results supported the study hypothesis of an association between students' orientations and their gender, choice of nursing speciality, problems with nursing studies and intention to stay in nursing. However, the hypothesis of an association between students' pre-educational nursing experiences and orientation to nursing was not supported. The contradictions between students' orientation to nursing and the philosophy of nursing underlying the study programme may be a source of motivational problems and dissatisfaction with nursing education

  20. Object-oriented Persistent Homology.

    Persistent homology provides a new approach for the topological simplification of big data via measuring the life time of intrinsic topological features in a filtration process and has found its success in scientific and engineering applications. However, such a success is essentially limited to qualitative data classification and analysis. Indeed, persistent homology has rarely been employed for quantitative modeling and prediction. Additionally, the present persistent homology is a passive tool, rather than a proactive technique, for classification and analysis. In this work, we outline a general protocol to construct object-oriented persistent homology methods. By means of differential geometry theory of surfaces, we construct an objective functional, namely, a surface free energy defined on the data of interest. The minimization of the objective functional leads to a Laplace-Beltrami operator which generates a multiscale representation of the initial data and offers an objective oriented filtration process. The resulting differential geometry based object-oriented persistent homology is able to preserve desirable geometric features in the evolutionary filtration and enhances the corresponding topological persistence. The cubical complex based homology algorithm is employed in the present work to be compatible with the Cartesian representation of the Laplace-Beltrami flow. The proposed Laplace-Beltrami flow based persistent homology method is extensively validated. The consistence between Laplace-Beltrami flow based filtration and Euclidean distance based filtration is confirmed on the Vietoris-Rips complex for a large amount of numerical tests. The convergence and reliability of the present Laplace-Beltrami flow based cubical complex filtration approach are analyzed over various spatial and temporal mesh sizes. The Laplace-Beltrami flow based persistent homology approach is utilized to study the intrinsic topology of proteins and fullerene molecules. Based on a

    Full Text Available The practice of financial analysis has been immeasurably strengthened in recent years thanks to the ongoing evolution of computerized approaches in the form of spreadsheets and computer-based financial models of different types. These devices not only relieved the analyst's computing task, but also opened up a wide range of analyzes and research into alternative sensitivity, which so far has not been possible. The main potential for object-oriented financial analysis consists in enormously expanding the analyst's capabilities through an online knowledge and information interface that has not yet been achieved through existing methods and software packages.

    Until recently, the formal treatment of control room procedures for upset conditions in nuclear power plants has been event-oriented. This orientation was not so much a reflection of power plant operating practice as it was a reflection of design-oriented thinking - design-basis events, therefore event-oriented procedures. Event orientation is not common in other professions. In the medical profession, for example, the stabilization of vital functions through a symptoms-oriented approach has priority over diagnosis and prognosis. The American nuclear power industry has initiated programs for the development and application of a symptoms-oriented approach for handling upset conditions. Canadian programs have independently paralleled the US programs. This article describes the rationale and current applications of the Canadian programs and identifies the relevance of a generic symptoms-based emergency procedure to current operating practices

    Ramachandran, Sohini; Rosenberg, Noah A.

    2012-01-01

    The geographic distribution of genetic variation reflects trends in past population migrations, and can be used to make inferences about these migrations. It has been proposed that the east-west orientation of the Eurasian landmass facilitated the rapid spread of ancient technological innovations across Eurasia, while the north-south orientation of the Americas led to a slower diffusion of technology there. If the diffusion of technology was accompanied by gene flow, then this hypothesis predicts that genetic differentiation in the Americas along lines of longitude will be greater than that in Eurasia along lines of latitude. We use 678 microsatellite loci from 68 indigenous populations in Eurasia and the Americas to investigate the spatial axes that underlie population-genetic variation. We find that genetic differentiation increases more rapidly along lines of longitude in the Americas than along lines of latitude in Eurasia. Distance along lines of latitude explains a sizeable portion of genetic distance in Eurasia, whereas distance along lines of longitude does not explain a large proportion of Eurasian genetic variation. Genetic differentiation in the Americas occurs along both latitudinal and longitudinal axes and has a greater magnitude than corresponding differentiation in Eurasia, even when adjusting for the lower level of genetic variation in the American populations. These results support the view that continental orientation has influenced migration patterns and has played an important role in determining both the structure of human genetic variation and the distribution and spread of cultural traits.

  18. Coordination dynamics of elliptic shape drawing: effects of orientation and eccentricity.

    Science.gov (United States)

    Danna, Jérémy; Athènes, Sylvie; Zanone, Pier-Giorgio

    2011-08-01

    The aim of the present study was to show the effect of orientation on producing ellipses of various eccentricities. Ten right-handed adults were required to reproduce eight series of 84 ellipses on a graphic tablet at spontaneous speed. The ellipses displayed seven eccentricities, corresponding to the Lissajous plot produced by two orthogonal harmonic oscillators whose relative phase (RP) varied from 0° (a line) to 90° (a circle), and twelve orientations, the long axis of the ellipses aligned in a direction ranging from three to nine o'clock with respect to the body transverse plane. Results confirmed the participant's preference for two eccentricities, 0° and 45°, that is, a line and an ellipse of intermediate eccentricity, respectively. Except for the circle, insensitive to orientation by definition, orientation became a cogent constraint: In the 10:30 o'clock direction, line drawing (0° RP) increased in variability and the intermediate ellipse (45° RP) was attracted towards a circle (90° RP). These findings suggest an interaction between orientation effects, putatively due to differences in the motion of the wrist and fingers, and eccentricity effects, which may pertain to preferences arising from the non-linear coupling between the effectors.

    The Nasca Lines are located in the Pampa region of Peru, the desolate plain of the Peruvian coast 400 km south of Lima. The Lines were first spotted when commercial airlines began flying across the Peruvian desert in the 1920's. Passengers reported seeing 'primitive landing strips' on the ground below. The Lines were made by removing the iron-oxide coated pebbles which cover the surface of the desert. When the gravel is removed, they contrast with the light color underneath. In this way the lines were drawn as furrows of a lighter color. On the pampa, south of the Nasca Lines, archaeologists have now uncovered the lost city of the line-builders, Cahuachi. It was built nearly two thousand years ago and was mysteriously abandoned 500 years later. This ASTER sub-image covers an area of 14 x 18 km, was acquired on December 22, 2000, and is located at 14.7 degrees south latitude and 75.1 degrees west longitude.

    Full Text Available The effect of micro ridges on orientation of cultured cells has been studied in vitro. Several patterns of micro ridges have been fabricated on a transparent polydimethylsiloxane disk with the photo lithography technique. The ridges consist of several lines of rectangular column: the width of 0.003 mm, the interval of 0.007 mm. Variation has been made on the height of the ridge between 0.0003 mm and 0.0035 mm. C2C12 (mouse myoblast cell line originated with cross-striated muscle of C3H mouse was cultured on the disk with the micro ridges for one week and was observed with an inverted phase contrast microscope. The experimental results show that cells adhere on the top of the ridge and align to the longitudinal direction of the micro ridges with the height between 0.0015 mm and 0.0025 mm.

  1. Isochronous sequential presentation helps children orient their attention in time.

    Full Text Available Knowing when an event is likely to occur allows attentional resources to be oriented towards that moment in time, enhancing processing of the event. We previously found that children (mean age 11 years are unable to use endogenous temporal cues (line length to orient attention in time, despite being able to use endogenous spatial cues (arrows to orient attention in space. Arrow cues, however, may have proved beneficial by engaging exogenous (automatic, as well as endogenous (voluntary, orienting mechanisms. We therefore conducted two studies in which the exogenous properties of visual temporal cues were increased, to examine whether this helped children orient their attention in time. In the first study, the location of an imperative target was predicted by the direction of a left or right spatial arrow cue while its onset was predicted by the relative duration of a short or long temporal cue. To minimise the influence of rhythmic entrainment in the temporal condition, target onset time (500ms/1100ms was deliberately chosen so as not to precisely match the duration of the temporal cue (100ms/400ms. Targets appeared either at cued locations/onset times (valid trials or at unexpected locations/onset times (invalid trials. Adults’ response times were significantly slower for invalid versus valid trials, in both spatial and temporal domains. Despite being slowed by invalid spatial cues, children (mean age 10.7 years were unperturbed by invalid temporal cues, suggesting that these duration-based temporal cues did not help them orient attention in time. In the second study, we enhanced the exogenous properties of temporal cues further, by presenting multiple temporal cues in an isochronous (rhythmic sequence. Again, to minimise automatic entrainment, target onset did not match the isochronous interval. Children (mean age 11.4 years, as well as adults, were now significantly slowed by invalid cues in both the temporal and spatial dimension. The

  6. Collisional transfer of population and orientation in NaK.

    Collisional satellite lines with |ΔJ| ≤ 58 have been identified in recent polarization spectroscopy V-type optical-optical double resonance (OODR) excitation spectra of the Rb(2) molecule [H. Salami et al., Phys. Rev. A 80, 022515 (2009)]. Observation of these satellite lines clearly requires a transfer of population from the rotational level directly excited by the pump laser to a neighboring level in a collision of the molecule with an atomic perturber. However to be observed in polarization spectroscopy, the collision must also partially preserve the angular momentum orientation, which is at least somewhat surprising given the extremely large values of ΔJ that were observed. In the present work, we used the two-step OODR fluorescence and polarization spectroscopy techniques to obtain quantitative information on the transfer of population and orientation in rotationally inelastic collisions of the NaK molecules prepared in the 2(A)(1)Σ(+)(v' = 16, J' = 30) rovibrational level with argon and potassium perturbers. A rate equation model was used to study the intensities of these satellite lines as a function of argon pressure and heat pipe oven temperature, in order to separate the collisional effects of argon and potassium atoms. Using a fit of this rate equation model to the data, we found that collisions of NaK molecules with potassium atoms are more likely to transfer population and destroy orientation than collisions with argon atoms. Collisions with argon atoms show a strong propensity for population transfer with ΔJ = even. Conversely, collisions with potassium atoms do not show this ΔJ = even propensity, but do show a propensity for ΔJ = positive compared to ΔJ = negative, for this particular initial state. The density matrix equations of motion have also been solved numerically in order to test the approximations used in the rate equation model and to calculate fluorescence and polarization spectroscopy line shapes. In addition, we have measured

    Grain oriented fabrication of ceramics utilizes the presence of some form of anisotropy in the particles of the starting material to obtain textured microstructures. The molten salt, or flux method, a popular technique for growing crystals and particles with anisotropic morphology, is utilized in this study. The formation of Ba2YCu3O(7-x) in the presence of molten salts of Na, K, Li belonging to chloride and sulfate systems does not appear feasible in the temperature range up to 900 C. Researchers also present the results of studies in using BaY2CuO5 as seed crystals in the formation of Ba2YCu3O(7-x) wherein BaY2CuO5 has been observed to have better stability in water and against most of the salts as compared to Ba2YCu3O(7-x). Additional results of molten salt processing of bismuth systems are also presented.

    Full Text Available Over the past 30 years research on Entrepreneurship Orientation (EO has provided valuable information regarding strategy, entrepreneurship and aspects of performance at the firm-level. In the entrepreneurial universe, microenterprises play a very special role in the business context of the economy. However, they have not been relatively present in the EO research. This paper studies the EO-performance relationship in a group of microenterprises in Mexico and includes the Dominant Logic (DL as a variable that moderates this relationship. The results indicate that risk taking, proactiveness and competitive aggressiveness variables from the EO influence the microenterprise performance. In addition, the external DL conceptualization moderates the EO-performance relationship. This paper shows the conclusions of the investigation as well as the limitations and identifies future research methods.

    The Moon is the most familiar example of the many satellites that exhibit synchronous rotation. For the Moon there is Lunar Laser Ranging measurements of tides and three-dimensional rotation variations plus supporting theoretical understanding of both effects. Compared to uniform rotation and precession the lunar rotational variations are up to 1 km, while tidal variations are about 0.1 m. Analysis of the lunar variations in pole direction and rotation about the pole gives moment of inertia differences, third-degree gravity harmonics, tidal Love number k2, tidal dissipation Q vs. frequency, dissipation at the fluid-core/solid-mantle boundary, and emerging evidence for an oblate boundary. The last two indicate a fluid core, but a solid inner core is not ruled out. Four retroreflectors provide very accurate positions on the Moon. The experience with the Moon is a starting point for exploring the tides, rotation and orientation of the other synchronous bodies of the solar system.

    Full Text Available In the recent years, research of special compiler techniques and algorithms for embedded processors broaden the knowledge of how to achieve better compiler performance in irregular processor architectures. However, industrial strength compilers, besides ability to generate efficient code, must also be robust, understandable, maintainable, and extensible. This raises the need for compiler infrastructure that provides means for convenient implementation of embedded processor oriented compiler techniques. Cirrus Logic Coyote 32 DSP is an example that shows how traditional compiler infrastructure is not able to cope with the problem. That is why the new compiler infrastructure was developed for this processor, based on research. in the field of embedded system software tools and experience in development of industrial strength compilers. The new infrastructure is described in this paper. Compiler generated code quality is compared with code generated by the previous compiler for the same processor architecture.

  16. Malaysian meteoric water line

    The quest for Malaysian meteoric water line began in 1981 when environmental isotope hydrology was introduced. In the 1980, and with the establishment of three stations at Pengkalan Chepa, Kepala Batas and Kuah, the Malaysian Meteoric Water Line acquired then was δD = 8δ 18 O + 12.68. With the addition of another four stations, by the end of 1990s, the Malaysian Meteoric Water Line for the decade was established as δD = 8 δ 18 O + 11.76. Taking the overall result between 1980 and mid 2000s the Malaysian Meteoric Water Line was established as δD = 8 δ 18 O + 13.255 and the weighted mean precipitation is (-7.64, -46.74). In establishing this meteoric water line it was observed that the higher altitude station manifested poorer stable isotopes content as compared to lower altitude station. It was also observed that as the amount of rain increased, the stable isotopes content would decrease and vice versa. The effect is reversed when the amount is due to monsoon rains and tropical storms. (Author)

  17. Tornadogensis within Hurricanes Based on the Orientation of the Rainband to the Coast after Landfall

    Etten-Bohm, M.

    2015-12-01

    The focus of this study is to investigate the development of tornadoes within the rainband of a hurricane for various orientations of the rainband when a hurricane makes landfall. The rainband of a hurricane is a common area where tornadogenesis is found depending on the size, intensity, and orientation of the rain band when the storm makes landfall. As a hurricane approaches a coast line, land-surface roughness contributes to surface friction, which can contribute in tornadogenesis. The orientation of the rainband may play a part in the type of supercells that are formed in that rainband and the number and intensity of the tornadoes produced. This study will investigate if the orientation of the rainband leads to the direction in which the supercells rotate, whether clockwise or counter-clockwise, and the scale and intensity of the tornadoes produced.

    Extended continental shelf (ECS) interest has provided a vehicle for renewed scientific study of the geologic framework of the U.S. Line Islands. In support of ECS studies, GLORIA sidescan sonar imagery has been refreshed and re-released. New multibeam bathymetry and backscatter data and a compilation of bathymetric tracks of opportunity enhance the credibility of new backscatter interpretations. Two-channel seismic reflection data collected during the GLORIA program in 1991 have been reprocessed and compiled into a digital database and have yielded a new understanding of sediment distribution and basement morphology within the 200 nautical mile exclusive economic zone (EEZ) surrounding Kingman Reef and Palmyra Atoll. Kingman Reef and Palmyra Atoll are small islands today. We infer that they are the last subaerial remnants of what was once a complex volcanic island, made up of no fewer than 8 different volcanic centers and spanning roughly 200 km in total diameter. Edifice heights above the immediately surrounding volcanic basement exceed 3000 m, and in several cases exceed 4000 m. Voluminous sediment accumulations flanking these now-submerged and significantly buried edifices point to their past existence as shallow-water or emergent volcanic systems capable of producing large quantities of volcaniclastic as well as carbonate sediment quite different from the thinner layer of pelagic sediment blanketing the adjacent central Pacific deep sea floor. The sediment pond east of Palmyra Atoll, in a perched basin near the center of this ancient complex, exceeds 1200 m in thickness. The Kingman-Palmyra region today is a showcase of mass transport features, with rugged erosional topography on steep volcanic flanks, a collapsed or eroding carbonate platform covering part of the central complex, and wide, sinuous leveed channels sweeping predominantly toward the north, carrying sediment away from the remnant high and out onto the deep sea floor to the east of the Line

  19. Perceptions of Sexual Orientation From Minimal Cues.

    2017-01-01

    People derive considerable amounts of information about each other from minimal nonverbal cues. Apart from characteristics typically regarded as obvious when encountering another person (e.g., age, race, and sex), perceivers can identify many other qualities about a person that are typically rather subtle. One such feature is sexual orientation. Here, I review the literature documenting the accurate perception of sexual orientation from nonverbal cues related to one's adornment, acoustics, actions, and appearance. In addition to chronicling studies that have demonstrated how people express and extract sexual orientation in each of these domains, I discuss some of the basic cognitive and perceptual processes that support these judgments, including how cues to sexual orientation manifest in behavioral (e.g., clothing choices) and structural (e.g., facial morphology) signals. Finally, I attend to boundary conditions in the accurate perception of sexual orientation, such as the states, traits, and group memberships that moderate individuals' ability to reliably decipher others' sexual orientation.

    We discuss a number of open issues within object-oriented programming. The central mechanisms of object-oriented programming appeared with Simula, developed more than 30 years ago; these include class, subclass, virtual function, active object and the first application framework, Class Simulation....... The core parts of object-oriented programming should be well understood, but there are still a large number of issues where there is no consensus. The term object-orientation has been applied to many subjects, such as analysis, design implementation, data modeling in databases, and distribution....... In this paper the term object-oriented programming is meant to cover all these subjects, since one of the advantages of object-orientation is that it provides a unified approach to these subjects. The issues being discussed in this paper are the following: modeling versus reuse as the main benefit of object...

    Full Text Available When creating an artwork, the artist makes a decision regarding the orientation at which the work is to be hung based on their aesthetic judgement and the message conveyed by the piece. Is the impact or aesthetic appeal of a work diminished when it is hung at an incorrect orientation? To investigate this question, Experiment 1 asked whether naïve observers can appreciate the correct orientation (as defined by the artist of 40 modern artworks, some of which are entirely abstract. Eighteen participants were shown 40 paintings in a series of trials. Each trial presented all four cardinal orientations on a computer screen, and the participant was asked to select the orientation that was most attractive or meaningful. Results showed that the correct orientation was selected in 48% of trials on average, significantly above the 25% chance level, but well below perfect performance. A second experiment investigated the extent to which the 40 paintings contained recognisable content, which may have mediated orientation judgements. Recognition rates varied from 0% for seven of the paintings to 100% for five paintings. Orientation judgements in Experiment 1 correlated significantly with “meaningful” content judgements in Experiment 2: 42% of the variance in orientation judgements in Experiment 1 was shared with recognition of meaningful content in Experiment 2. For the seven paintings in which no meaningful content at all was detected, 41% of the variance in orientation judgements was shared with variance in a physical measure of image content, Fourier amplitude spectrum slope. For some paintings, orientation judgements were quite consistent, despite a lack of meaningful content. The origin of these orientation judgements remains to be identified.

    A mathematical model for fibrous structures using a direction dependent scaling law is presented. The orientation of fibrous nets (e.g. paper) is analysed with a method based on the curvelet transform. The curvelet-based orientation analysis has been tested successfully on real data from paper samples: the major directions of fibrefibre orientation can apparently be recovered. Similar results are achieved in tests on data simulated by the new model, allowing a comparison with ground truth

    Body orientation provides an important cue to other individuals' focus of attention, particularly when one is viewing them at a distance. Single-cell recording in macaques has identified cells in the superior temporal sulcus that show a view-selective response to particular body orientations. Whether similar separable coding is found in humans is not known, and there is currently no functional account of the visual representation of seen body orientation. This study addressed this issue using visual adaptation. Experiment 1 demonstrated distinct channels that code left- and right-oriented bodies. Experiment 2 investigated whether the visual representation of body orientation is best accounted for by an opponent-coding system, which has been shown to account for the visual representation of facial identity, or by a multichannel system, which provides the optimal account of coding line orientation and direction of motion. Our results provide evidence for multichannel coding of seen body orientation, with separate channels (or neuronal populations) selectively tuned to different body directions.

    Emplacement borehole orientation directly impacts many aspects of the Engineered Barrier System (EBS) and interactions with the near field environment. This paper considers the impacts of orientation on the hydrologic portion of the environment and its interactions with the EBS. The hydrologic environment is considered from a conceptual standpoint, the numerical analyses are left for subsequent work. As reported in this paper, several aspects of the hydrological environment are more favorable for long term performance of vertically oriented rather than horizontally oriented Waste Packages. 19 refs., 15 figs

    Reddy, K Anki; Kumaran, V; Talbot, J

    2009-09-01

    Using even driven simulations, we show that homogeneously sheared inelastic dumbbells in two dimensions are randomly orientated in the limit of low density. As the packing fraction is increased, particles first tend to orient along the extensional axis, and then as the packing fraction is further increased, the alignment shifts closer to the flow axis. The orientational order parameter displays a continuous increase with packing fraction and does not appear to exhibit a universal scaling with elongation. Except at the highest packing fractions, the orientational distribution function can be reconstructed with only the first coefficient of the Fourier expansion.

  14. Dynamics of market orientation in Croatian economy

    2011-12-01

    Full Text Available It was the goal of this research to examine the dynamics of Croatian transformation to market orientation and test whether the market orientation model changes with time as the business environment changes. Based on the literature analysis, we proposed a hypothetical model which relies on behavioural approach in understanding market orientation. To empirically test the hypothetical model, we used data previously collected for 2001, and by replicating the same questionnaire now collected data for 2011. Data was analyzed by hierarchical regression analysis on the two sets of data. Our findings reveal that Croatian organizations reached the level of moderate market orientation leaving space for improvement. Findings also reveal that higher level of market orientation correlates with higher business performance. Furthermore, with development of ICT, the model of market orientation modified in time in a way that in predicting successful market oriented reaction, specific information on consumer satisfaction gains importance, while general information from competitor and consumer databases lose importance. Despite the changes in the relationships among the elements of market orientation, the model itself similarly predicts performance today as it did ten years ago. Managers are advised to increase implementation of market orientation especially focusing on market responsiveness as such behaviour will lead to better performance.

    2012-03-01

    Full Text Available he study investigates the interrelationships between different on-line and off-line measures for assessing metacognition. The participants were 47 fifth grade elementary students. Metacognition was assessed through two off-line and two on-line measures. The off-line measures consisted of a teacher rating scale and a self-report questionnaire. The on-line measures were thinking aloud protocols and accuracy ratings of text comprehension. The results showed positive significant correlation between data from two off-line measures and negative significant correlation between data from two on-line measures. The off-line metacognitive measures had non-significant correlations with all on-line measures. Principal Component Analysis, performed on four metacognitive measures, yielded a two-factor solution and this two-factor solution accounted for 71.5 % of the sample variance. The data from two off-line measures loaded on the first component with a variance proportion of 38.6 % and the data from two on-line measures loaded on the second component with a variance proportion of 32.9%. The findings of the study showed that metacognitive processes form a complex structure that needs to be assessed using various methods. However, in the multi-method studies, using on-line and off-line measures together will be appropriate rather than using only on-line measures or only off-line measures.

    2013-03-01

    Full Text Available Interesting cases of human quadrupedalism described by Uner Tan and colleagues (2005-2012 have attracted the attention of geneticists, neurologists and anthropologists. Since his first publications in 2005, the main attention has focused on the genetic aspects of disorders that lead to quadrupedalism within an evolutionary framework. In recent years this area has undergone a convincing critique (Downey 2010 and ended with a call "... to move in a different direction … away from thinking solely in terms of genetic abnormality and evolutionary atavism". We consider quadrupedalism as a ‘natural experiment’ that may contribute to our knowledge of the physiological mechanisms underlying our balance system and our tendency toward normal (upright posture. Bipedalism necessitates a number of characteristics that distinguish us from our ancestors and present-day mammals, including: size and shape of the bones of the foot, structure of the axial and proximal musculature, and the orientation of the human body and head. In this review we address the results of experimental studies on the mechanisms that stabilize the body in healthy people, as well as how these mechanisms may be disturbed in various forms of clinical pathology. These disturbances are related primarily to automatic rather than voluntary control of posture and suggest that human quadrupedalism is a behavior that can result from adaptive processes triggered by disorders in postural tone and environmental cues. These results will serve as a starting point for comparing and contrasting bi- and quadrupedalism.

    In the framework of the RISET Project (Interfaculty Network of Support to Education and Technology) an educational tool for introducing risk analysis has been developed. This workshop enables to carry a group of students (role-play game) through a step-by-step process of risk identification and quantification. The aim is to assess risk in a characteristic alpine village regarding natural hazards (rockfall, snow avalanche, flooding…) and is oriented to affected objects such as buildings, infrastructures... The workshop contains the following steps: 1.- Planning of the study and definition of stakeholders 2.- Hazard identification 3.- Risk analysis 4.- Risk assessment 5.- Proposition of mitigation measures 6- Risk management and cost-benefit analysis. During the process, information related to past events and useful concepts are provided in order to bring up discussion and decision making. The Risk Matrix and other graphical tools allow having a visual representation of the risk level and help to prioritize counter measures. At the end of the workshop, there is the possibility to compare the results between different groups and print out a summarizing report. This approach provides a rapid and comprehensible risk evaluation. The workshop is accessible from the internet and will be used for educational purposes at bachelor and master level as well as for external persons dealing with risk analysis.

    2014-09-23

    Spatular terminals on the toe pads of a gecko play an important role in directional adhesion and friction required for reversible attachment. Inspired by the toe pad design of a gecko, we study friction of polydimethylsiloxane (PDMS) micropillars terminated with asymmetric (spatular-shaped) overhangs. Friction forces in the direction of and against the spatular end were evaluated and compared to friction forces on symmetric T-shaped pillars and pillars without overhangs. The shape of friction curves and the values of friction forces on spatula-terminated pillars were orientation-dependent. Kinetic friction forces were enhanced when shearing against the spatular end, while static friction was stronger in the direction toward the spatular end. The overall friction force was higher in the direction against the spatula end. The maximum value was limited by the mechanical stability of the overhangs during shear. The aspect ratio of the pillar had a strong influence on the magnitude of the friction force, and its contribution surpassed and masked that of the spatular tip for aspect ratios of >2.

    This study examines the effect of airflow orientation with respect to the strip active electrode on concentration of ozone and nitrogen dioxide produced in a planar generator based on the surface dielectric barrier discharge. The orientation of the airflow was tested in parallel and perpendicular with respect to the strips. It was found that in the investigated range of average discharge power, the ozone concentration increases approximately by 25% when airflow was oriented in parallel with respect to the strips in comparison with perpendicular orientation of the airflow. Similarly the increase of nitrogen dioxide concentration was observed for parallel orientation of the airflow with respect to the strips in comparison with the perpendicular orientation of the airflow. Within the range of wavelengths from 250 to 1100 nm, the changes of intensities of spectral lines associated with airflow orientation have been observed. A 3D numerical model describing ion trajectories and airflow patterns have also been developed.

A welding stud detection method based on line structured light is proposed. Firstly, the adaptive threshold is designed to calculate the binary images. Then, the light stripes of the image are extracted after skeleton line extraction and morphological filtering. The direction vector of the main light stripe is calculated using the length of the light stripe. Finally, the gray projections along the orientation of the main light stripe and the vertical orientation of the main light stripe are computed to obtain curves of gray projection, which are used to detect the studs. Experimental results demonstrate that the error rate of proposed method is lower than 0.1%, which is applied for automobile manufacturing.

    2015-01-01

    Full Text Available The aim of the article was to find nexus between brand orientation and financial performance in companies doing business in Serbia. We surveyed general managers, marketing managers, and brand managers in order to examine their views on the brand orientation dimensions of their companies. We matched the survey results with financial performance of those companies (EBITDA margin in order to find linkages between these variables. We got expected results in the sense that strong brand orientation and weaker brand barriers lead to better financial performance. Overall brand orientation is significantly positively correlated with EBITDA margin, and brand barriers are significantly negatively correlated with that measure. We analysed the brand orientation and brand barriers between groups of companies classified according to their size, internationalization, origin of company ownership, origin of brand, specific business area of key brands and type of goods sold. Interestingly, there are undoubted differences in brand orientation and brand barriers only between foreign and domestic companies. These differences could be seen as one of the main reasons of differences between their EBITDA margins. Also, we saw some differences in brand orientation in case of companies with international brands in relation to companies with domestic brands, but those differences are fewer and smaller. We did not find any other statistically significant difference. The significance of the paper is in emphasizing that development of brand orientation of domestic companies could lead to improvement of their profitability and competitiveness.

  9. Orientation field estimation for latent fingerprint enhancement.

    Science.gov (United States)

    Feng, Jianjiang; Zhou, Jie; Jain, Anil K

    2013-04-01

    Identifying latent fingerprints is of vital importance for law enforcement agencies to apprehend criminals and terrorists. Compared to live-scan and inked fingerprints, the image quality of latent fingerprints is much lower, with complex image background, unclear ridge structure, and even overlapping patterns. A robust orientation field estimation algorithm is indispensable for enhancing and recognizing poor quality latents. However, conventional orientation field estimation algorithms, which can satisfactorily process most live-scan and inked fingerprints, do not provide acceptable results for most latents. We believe that a major limitation of conventional algorithms is that they do not utilize prior knowledge of the ridge structure in fingerprints. Inspired by spelling correction techniques in natural language processing, we propose a novel fingerprint orientation field estimation algorithm based on prior knowledge of fingerprint structure. We represent prior knowledge of fingerprints using a dictionary of reference orientation patches. which is constructed using a set of true orientation fields, and the compatibility constraint between neighboring orientation patches. Orientation field estimation for latents is posed as an energy minimization problem, which is solved by loopy belief propagation. Experimental results on the challenging NIST SD27 latent fingerprint database and an overlapped latent fingerprint database demonstrate the advantages of the proposed orientation field estimation algorithm over conventional algorithms.

  3. Visual coherence for large-scale line-plot visualizations

    KAUST Repository

    Muigg, Philipp

    2011-06-01

    Displaying a large number of lines within a limited amount of screen space is a task that is common to many different classes of visualization techniques such as time-series visualizations, parallel coordinates, link-node diagrams, and phase-space diagrams. This paper addresses the challenging problems of cluttering and overdraw inherent to such visualizations. We generate a 2x2 tensor field during line rasterization that encodes the distribution of line orientations through each image pixel. Anisotropic diffusion of a noise texture is then used to generate a dense, coherent visualization of line orientation. In order to represent features of different scales, we employ a multi-resolution representation of the tensor field. The resulting technique can easily be applied to a wide variety of line-based visualizations. We demonstrate this for parallel coordinates, a time-series visualization, and a phase-space diagram. Furthermore, we demonstrate how to integrate a focus+context approach by incorporating a second tensor field. Our approach achieves interactive rendering performance for large data sets containing millions of data items, due to its image-based nature and ease of implementation on GPUs. Simulation results from computational fluid dynamics are used to evaluate the performance and usefulness of the proposed method. © 2011 The Author(s).

    This paper discusses the process of identifying factors that influence the contamination level of a given decision area and then determining the likelihood that the area remains unacceptable. This process is referred to as lines of evidence. These lines of evidence then serve as inputs for the stratified compliance sampling (SCS) method, which requires a decision area to be divided into strata based upon contamination expectations. This is done in order to focus sampling efforts more within stratum where contamination is more likely and to use the domain knowledge about these likelihoods of the stratum remaining unacceptable to buy down the number of samples necessary, if possible. Two different building scenarios were considered as an example (see Table 3.1). SME expertise was elicited concerning four lines of evidence factors (see Table 3.2): 1) amount of contamination that was seen before decontamination, 2) post-decontamination air sampling information, 3) the applied decontaminant information, and 4) the surface material. Statistical experimental design and logistic regression modelling were used to help determine the likelihood that example stratum remained unacceptable for a given example scenario. The number of samples necessary for clearance was calculated by applying the SCS method to the example scenario, using the estimated likelihood of each stratum remaining unacceptable as was determined using the lines of evidence approach. The commonly used simple random sampling (SRS) method was also used to calculate the number of samples necessary for clearance for comparison purposes. The lines of evidence with SCS approach resulted in a 19% to 43% reduction in total number of samples necessary for clearance (see Table 3.6). The reduction depended upon the building scenario, as well as the level of percent clean criteria. A sensitivity analysis was also performed showing how changing the estimated likelihoods of stratum remaining unacceptable affect the number

  6. Asymmetries in perception of 3D orientation.

    Directory of Open Access Journals (Sweden)

    Allan C Dobbins

    2010-03-01

    Full Text Available Visual scene interpretation depends on assumptions based on the statistical regularities of the world. People have some preference for seeing ambiguously oriented objects (Necker cubes as if tilted down or viewed from above. This bias is a near certainty in the first instant (approximately 1 s of viewing and declines over the course of many seconds. In addition, we found that there is modulation of perceived orientation that varies with position--for example objects on the left are more likely to be interpreted as viewed from the right. Therefore there is both a viewed-from-above prior and a scene position-dependent modulation of perceived 3-D orientation. These results are consistent with the idea that ambiguously oriented objects are initially assigned an orientation consistent with our experience of an asymmetric world in which objects most probably sit on surfaces below eye level.

    The general Method of Lines (MOL) procedure provides a flexible format for the solution of all the major classes of partial differential equations (PDEs) and is particularly well suited to evolutionary, nonlinear wave PDEs. Despite its utility, however, there are relatively few texts that explore it at a more advanced level and reflect the method''s current state of development.Written by distinguished researchers in the field, Adaptive Method of Lines reflects the diversity of techniques and applications related to the MOL. Most of its chapters focus on a particular application but also provide a discussion of underlying philosophy and technique. Particular attention is paid to the concept of both temporal and spatial adaptivity in solving time-dependent PDEs. Many important ideas and methods are introduced, including moving grids and grid refinement, static and dynamic gridding, the equidistribution principle and the concept of a monitor function, the minimization of a functional, and the moving finite elem...

    A method is presented for forming refractory liners in cylindrical reaction vessels used for the reductlon of uranium tetrafluoride to metallic uranium. A preliminary form, having positioning lugs attached thereto, is inserted into the reaction vessel and the refractory powder, usually CaO, is put in the annular space between the form and the inner wall of the reaction vessel. A jolting table is used to compact this charge of liner material ln place, and after thls has been done, the preliminary form is removed and the flnal form or plug is lnserted without disturbing the partially completed lining. The remainder of the lining charge is then introduced and compacted by jolting, after which the form is removed.

    Nuttall, K.R.; Gardner, P.R.

    1991-01-01

    Westinghouse Hanford Company is developing a desk-top simulation based training program on the operation of the Remote Mechanical C (RMC) Line process in the Plutonium Finishing Plant on the Hanford site, Richland, Washington. Simulations display aod contioually update current values of system parameters on computer graphics of RMC line equipment. Students are able to operate a variety of controllers to maintain proper system status. Programmed faults, selectable by the course instructor, can be used to test student responses to off-normal events. Prior to operation of the simulation, students are given computer-based tutorials on the function, processes, operation, and error conditions associated with individual components. By including the capability of operating each individual component - valves, heaters, agitators, etc. - the computer-based training (CBT) lessons become an interactive training manual. From one perspective RMC represents one step in the diffusion of the well-known and well-documented simulator training activities for nuclear reactor operators to other training programs, equally critical, perhaps, but less well scrutinized in the past. Because of the slowly responding nature of the actual process, RMC can retain many of the capabilities of practice and testing in a simulated work environment while avoiding the cost of a full scale simulator and the exposure and waste developed by practice runs of the RMC line. From another perspective RMC suggests training advances even beyond the most faithful simulators. For example, by integrating CBT lessons with the simulation, RMC permits students to focus in on specific processes occurring inside chosen components. In effect, the interactive training manual is available on-line with the simulation itself. Cost are also discussed

  12. Line managers as marketers.

    Science.gov (United States)

    Rynne, T J

    1986-09-01

    Many hospital administrators and boards of directors, having overcome their initial opposition to advertising and hired a marketing professional, are wondering why their marketing programs have not accomplished all that they had hoped. The answer lies in their perception of who is responsible for marketing. Marketing is not a specialty separate from the disciplines of management--it is a basic management skill. Its goal is to satisfy the customer by providing products and services that meet the customer's needs, wants, and preferences. Line managers must understand the hospital's customers and make the critical day-to-day differences in satisfying them. They are the hospital's front-line marketers, and the marketing department's role is to support them in this function. The marketing department should develop the line managers' marketing skills by furnishing them with the appropriate tools: formats, models, examples, and instructions. In addition, the marketing staff should provide such specialized services as marketing research, ad agency management, and development of communications.

    We show the principles of the communication protocol, on-line calibration, off-line data format as well as basic visualisation and data analysis software implemented for the EUSO-TA on-ground experiment, being the first step towards implementation in a future space based mission. EUSO-TA is an on-ground detector for measuring UV (290–430 nm) light from extensive air showers induced by cosmic rays. It is a prototype experiment for the JEM-EUSO space-borne mission, built according to the same constraints of low mass, low power consumption and thus low computing power. Nevertheless, it needs to process a huge amount of data in short time, taking 2.5μs exposures for 2304 channels. The low processing power and high time resolution require an efficient communication protocol and simple yet powerful algorithms for on-line analysis. The off-line data format is designed for storing a huge amount of data, at the same time allowing easy access, analysis and sharing. Its structure is scalable and adjustable to different experimental designs. It is independent of the data origin, whether it is hardware or a Monte-Carlo simulator.

    Full Text Available Due to the large biases between the laboratory-calibrated values of the orientation parameters and their in-orbit true values, the initial direct georeferencing accuracy of the Ziyuan-3 (ZY-3 three-line camera (TLC images can only reach the kilometre level. In this paper, a point-based geometric calibration model of the ZY-3 TLCs is firstly established by using the collinearity constraint, and then a line-based geometric calibration model is established by using the coplanarity constraint. With the help of both the point-based and the line-based models, a feasible in-orbit geometric calibration approach for the ZY-3 TLCs combining ground control points (GCPs and ground control lines (GCLs is presented. Experimental results show that like GCPs, GCLs can also provide effective ground control information for the geometric calibration of the ZY-3 TLCs. The calibration accuracy of the look angles of charge-coupled device (CCD detectors achieved by using the presented approach reached up to about 1.0''. After the geometric calibration, the direct georeferencing accuracy of the ZY-3 TLC images without ground controls was significantly improved from the kilometre level to better than 11 m in planimetry and 9 m in height. A more satisfactory georeferencing accuracy of better than 3.5 m in planimetry and 3.0 m in height was achieved after the block adjustment with four GCPs.

    We show the principles of the communication protocol, on-line calibration, off-line data format as well as basic visualisation and data analysis software implemented for the EUSO-TA on-ground experiment, being the first step towards implementation in a future space based mission. EUSO-TA is an on-ground detector for measuring UV (290–430 nm) light from extensive air showers induced by cosmic rays. It is a prototype experiment for the JEM-EUSO space-borne mission, built according to the same constraints of low mass, low power consumption and thus low computing power. Nevertheless, it needs to process a huge amount of data in short time, taking 2.5μs exposures for 2304 channels. The low processing power and high time resolution require an efficient communication protocol and simple yet powerful algorithms for on-line analysis. The off-line data format is designed for storing a huge amount of data, at the same time allowing easy access, analysis and sharing. Its structure is scalable and adjustable to different experimental designs. It is independent of the data origin, whether it is hardware or a Monte-Carlo simulator. Use of object-oriented techniques and the ROOT framework allows rapid development of dedicated analysis software, such as a Python based quick-view program described herein. Basic capabilities of the software, such as display of the focal surface, light curves and calibration data are shown in this paper.

  18. Physiological and biomechanical aspects of orienteering.

    Science.gov (United States)

    Creagh, U; Reilly, T

    1997-12-01

    Orienteering is an endurance running event which differs from other running sports both in its cognitive element and in the type of terrain encountered. The demands of overcoming this terrain are not manifest in significant differences between orienteers and road runners in somatotype, though elite female orienteers have consistently been shown to have higher levels of adiposity (> 19%) than elite road runners. High aerobic power in orienteers (up to 63 and 76 ml/kg/min in women and men, respectively) is coupled with lower anaerobic performance. While leg strength is generally not high when compared with other athletic specialties, female orienteers have relatively good leg flexion strength. The energy cost of running is greatly increased in rough terrain. Oxygen cost was 26% higher while running in a forest when compared with road running. Biomechanical differences in stride pattern contribute towards this increased demand. Despite the high energy demands during competition, orienteers pace themselves such that their mean heart rate remains within the range of 167 to 172 beats/min, despite large fluctuations. The rough terrain encountered in orienteering results not only in a high energy cost but also in a higher incidence of sport-specific injuries, particularly to the ankle. Minor injuries such as cuts and bruises are common during competition.

The Geneva finals were hosted by the CERN Orienteering Club and concluded months of competitions held across 5 countries.   Women's World-Cup winner, Simone Niggli (centre).  © Ilknur Colak The final events of the Orienteering World Cup took place in the Old Town of Geneva and Saint-Cergue, with runners following routes prepared by the CERN Orienteering Club. Orienteering is a sport of navigation, using only a compass, map and your sense of direction. The objective is to get to all the points on the map as quickly as possible, choosing your own paths as you run. This was the CERN club’s first successful participation in the World Cup, cementing its reputation as a fixture in the international orienteering world. Orienteering is not your typical Swiss pastime. Developed in Scandinavia, the sport has been gaining popularity internationally. “...

    There has been interest in the relationship between homosexuality, gender role and suicide risk. Though homosexuals are more likely to identify as cross-gender, research has not simultaneously examined sexual orientation and gender role in assessing suicide risk. In the current study, the unique and interactive effects of sexual orientation and gender role were assessed in regard to suicidal ideation, related psychopathology and measures of coping. 77 participants were recruited from an undergraduate psychology subject pool (n=47) or from gay, lesbian and transgender student organizations (n=30) and assessed on measures of gender role, homosexuality, and psychopathology. Consistent with expectations, cross-gender role (i.e., personality traits associated with the opposite sex) is a unique predictor of suicidal symptoms. Moreover, gender role accounted for more of the overall variance in suicidal symptoms, positive problem orientation, peer acceptance and support, than sexual orientation. After accounting for gender role, sexual orientation contributed little to the variance in suicidal symptoms, associated pathology and problem-solving deficits. There was no support for gender role by sexual orientation interaction effects. The cross-sectional nature of the data limits statements regarding causality. Cross-gendered individuals, regardless of sexual orientation, appear to have higher risk for suicidal symptoms. Researchers and clinicians should assess gender role in evaluations of youth samples.

    Full Text Available Objective: The objective of this paper is to identify differences between measurement of organisational entrepreneurship in for-profit and non-profit context and to propose the measures aligned to non-profit organisations. The main research question is whether the scales designed to measure entrepreneurial orientation can be used in non-profit organisations and under which conditions. Research Design & Methods: Research methodology is based on review of research tools and measurement scales related to organisational entrepreneurship and comparison of for-profit and non-profit organisations, as well as their characteristics in the context of entrepreneurial orientation. Findings: Entrepreneurial orientation can be measured in non-profit organisations using existing scales that have been designed for business organisations, however they have to be modified, mostly in the dimension of competitive aggressiveness and autonomy. Additionally, the scale should be enriched with items related to cooperation with other organisations. Implications & Recommendations: It is necessary to develop methods and tools that enable the measurement of entrepreneurial orientation in non-profit organisation as well as comparative research on entrepreneurial orientation in for-profit and non-profit organisations. Contribution & Value Added: The originality of this work lies in studying some aspects of entrepreneurial orientation, that apply to the social context. Some suggestions were formulated relating to the utilisation of entrepreneurial orientation scales (originally designed for business enterprises in non-profit organisations.

  2. Preferred orientation of ettringite in concrete fractures

    Sulfate attack and the accompanying crystallization of fibrous ettringite [Ca6Al2(OH)12(SO4) 3·26H2O] cause cracking and loss of strength in concrete structures. Hard synchrotron X-ray microdiffraction is used to quantify the orientation distribution of ettringite crystals. Diffraction images are analyzed using the Rietveld method to obtain information on textures. The analysis reveals that the c axes of the trigonal crystallites are preferentially oriented perpendicular to the fracture surfaces. By averaging single-crystal elastic properties over the orientation distribution, it is possible to estimate the elastic anisotropy of ettringite aggregates. © 2009 International Union of Crystallography.

    This article summarises the principles of object-oriented philosophy and explains its similarities with, and differences from, the outlook of the natural sciences. Like science, the object-oriented position avoids the notion (quite common in philosophy) that the human-world relation is the ground of all others, such that scientific statements about the world would only be statements about the world as it is for humans. But unlike science, object-oriented metaphysics treats artificial, social, and fictional entities in the same way as natural ones, and also holds that the world can only be known allusively rather than directly.

  7. [Japan's Oriental medicine policy in colonial Korea].

    Science.gov (United States)

    Park, Yunjae

    2008-06-01

    During its colonization of Korea, the Japanese Empire used the Western medicine as a tool for advertising its advanced culture. However, the medical workforce available in Korea was insufficient. The Rule for Uisaeng (Oriental medicine practitioner) was an ordinance decreed in 1913 with a purpose of supplementing the medical workforce. As the Oriental medicine practitioners became official medical workforce, the Japanese Empire could mobilize them in a hygienic administration such as prevention of epidemics. The Uisaengs also tried to adapt themselves to the colonial environment by studying Western medicines. However, the distrust of the Japanese Empire in Oriental medicine continued until 1920s. Manchurian Incident in 1931 brought a change. As the relationship with China aggravated, the provision of medical herb became unstable and the Japanese Empire began to encourage using Oriental medical herb following the Movement for Improving Rural Region Economy. An attempt of the Japanese Empire to utilize the medical herb resulted in a plan to make the Oriental medical herb officinal. The goal was to organize and standardize the Oriental medical herb through a research by the Medical Herb Investigation Committee. However, the medical herb on the table was the one verified by the Western medicine. That is, it was not a traditional medical herb that uses the original theory of Oriental medicine. There was a minority opinion arguing that they should study the Oriental medicine itself. However, that argument was also based on the theory and principles of the Western medicine. Even though an attempt to make full use of Uisaengs expanded as the war continued, the major medical workforce that the Japanese Empire relied on was those trained in Western medicine. In other words, the Japanese Empire did not give a full credit to the Oriental medicine during the colonial era. During the colonization, Japanese Empire used Oriental medicine under the nominal reason of lack of medical

In particular we seek to address if entrepreneur behavior and firm practices are congruent with founding entrepreneur espoused support of sustainability. Our survey findings with thirty specialty food entrepreneurs suggest tenuous empirical support for the relationship of entrepreneur sustainable orientation, mindset and firm sustainable practices. However our qualitative results indicate positive relationships between sustainable orientation, mindset and practices. Evidence from this work highlights the critical role of founding entrepreneurs for successful implementation of sustainability along its multiple fronts including profitability.

  11. Liquid entrainment at an upward oriented vertical branch line from a horizontal pipe

    Science.gov (United States)

    Welter, Kent Byron

    Under simulated accident conditions, tees in the primary coolant loop of a Pressurized Water Reactor (PWR) can deviate from their original design purpose and become separators that effectively remove core heat sink capacity. This method of primary coolant removal is a phenomenological subset of phase separation known as liquid entrainment, whereby liquid is forced from its original path by the inertia of the gas. A comprehensive literature review revealed common deficiencies in previous studies. The Westinghouse AP600 advanced reactor design was chosen to assess the validity of entrainment models. Following a systematic scaling analysis of the prototypic design a model separate effects test was proposed and constructed at Oregon State University. Just under 100 tests were run to fill the deficiencies found in the literature review. New data from the Air-water Test Loop for Advanced Thermal-hydraulic Studies (ATLATS) could not be predicted by published correlations. A new theoretical model for predicting liquid entrainment onset and steady state entrainment was developed. Comparison with all available data shows a marked improvement for predicting the mass flow rate out the vertical branch.

    Gravitational theories do not admit gauge invariant local operators. We study the limits under which there exists a quasi-local description for a class of non-local gravitational observables where a sum over worldlines plays the role of the Wilson line for gauge theory observables. We study non-local corrections to the local description and circumstances where these corrections become large. We find that these operators are quasi-local in at space and AdS, but fail to be quasi-local in de Sitter space.

    The transmission of electrical signal through a coaxial line is not perfect and signal distortions are increased as much as the frequency spectrum is extended. We have designed and achieved passive filters (named equalizers) with transfer functions which are inverse of coaxial transfer functions. Doing so our attempt is to avoid definitive loss of information in the recorded data. The main feature of our equalization method lies in the fact it could be either an electrical or a numerical correction or both of them. Some examples in the use of this technique are also proposed [fr

  19. Strategic production line synchronisation

    Directory of Open Access Journals (Sweden)

    Hattingh, Teresa

    2016-08-01

    Full Text Available A study was conducted at the sole global producer of suspension struts for a particular vehicle manufacturer. This supplier is currently able to meet customer demand. However, it does so because of a large finished goods and work-in-progress (WIP inventory. The plant operates two production processes that are separated by a large buffer of WIP, which essentially decouples the production processes. This study aimed to reduce this WIP buffer; this would require the processes to become synchronised, bearing in mind that the reliability of delivery should not decrease. A tool that considers time, quality, and machine capacity was developed to assess the impact of line synchronisation on company performance figures. It was found that line synchronisation produced several benefits for the supplier, including batch size reduction, lower inventory levels, and associated shorter lead times. This further allowed the supplier to improve flow in the plant by introducing a pull system. Improved visual oversight could lead to further improved problem-solving and innovation.

    2003-01-01

    Electron back-scattered diffraction (EBSD) in scanning electron microscopy (SEM) is already extensively used for creating orientation-based microstructure images of polycrystalline materials. In an analogous way, Kikuchi patterns have been recently applied for creating polycrystalline orientation maps using a transmission electron microscope. Main components of the new system are similar to those of the SEM-based systems. The first steps are pattern acquisition and correction of the images. They are subsequently followed by automatic indexing of the patterns. Finally, from orientations obtained in a grid of points, a map is created. The system using transmission electron microscopy (TEM) has a good spatial resolution of about 10 nm. Its accuracy in orientation determination (∼0.1 deg. ) is better than the accuracy of EBSD systems

    Fashions change with time and beauty standards differ in different cultures. In recent years, there has been an increase in the number of immigrants to the United States from the Orient. The creation of an upper eyelid crease has been for the past several decades the most popular cosmetic procedure in many Asian countries. In order to perform this procedure to the satisfaction of an Oriental patient, the surgeon must know what the patient perceives as beautiful and the anatomic differences between the Oriental and the Occidental eyelids. In this paper with data collected from over 3,600 patients, we are presenting important statistics that enables the surgeon to understand better the Oriental mind and facilitate communications. The anatomic difference in the upper eyelid is also discussed.

    Kumar, K; Subramanian, R; Yauger, C

    1997-01-01

    Changes in the health care industry have profoundly affected hospital management and have caused severe declines in hospital profitability. In 1993, Health Care Management Review reported that the average operating profit margin, around 2% in 1984, had declined to a 0.2% loss by 1990. In the past, hospitals were buffered by entry regulations and cost reimbursement; thus, they rarely dealt with traditional market pressures. But the changed terrain means that competitive factors now underscore all strategic decisions. This study examines the strategic significance of market orientation in the health care industry. The authors identified forms of market orientation by emphasizing different components, and discovered that hospitals fell into four distinct clusters or groups. They also found a critical relationship between market orientation and performance scores on a number of criteria. Finally, the authors suggest that different forms of market orientation should be employed to target specific performance measures.

The study showed a significantly more intense orienting reaction in patients with night terrors than in normal subjects (Control Group I). Moreover, the orienting reaction intensity in subjects with night terrors was significantly lower than in patients with symptomatic epilepsy (Control Group II). The orienting reactions of patients with night terrors depended on the patient's age, the history of nocturnal episodes, and their clinical form, as well as on etiology.

    Many people believe that sexual orientation (homosexuality vs. heterosexuality) is determined by education and social constraints. There are, however, a large number of studies indicating that prenatal factors have an important influence on this critical feature of human sexuality. Sexual orientation is a sexually differentiated trait (over 90% of men are attracted to women and vice versa). In animals and men, many sexually differentiated characteristics are organized during early life by sex...

    2017-12-01

    Full Text Available Occurrence of the agent paradigm and its further applications have stimulated the emergence of new concepts and methodologies in computer science. Today terms like multi-agent system, agent-oriented methodology, and agent-oriented programming (AOP are widely used. The aim of this paper is to clarify the validity of usage of the terms AOP and AOP language. This is disclosed in two phases of an analysis process. Determining to which concepts, terms like agent, programming, object-oriented analysis and design, object-oriented programming, and agent-oriented analysis and design correspond is accomplished in the first phase. Analysis of several known agent system engineering methodologies in terms of key concepts used, final resulting artifacts, and their relationship with known programming paradigms and modern tools for agent system development is performed in the second phase. The research shows that in most cases in the final phase of agent system design and in the coding stage, the main artifact is an object, defined according to the rules of the object-oriented paradigm. Hence, we say that the computing society still does not have AOP owing to the lack of an AOP language. Thus, the term AOP is very often incorrectly assigned to agent system development frameworks that in most cases, transform agents into objects.DOI: 10.15181/csat.v5i1.1361

  7. ORIENTATION STRATEGIES FOR AERIAL OBLIQUE IMAGES

    Directory of Open Access Journals (Sweden)

    A. Wiedemann

    2012-07-01

    Full Text Available Oblique aerial images become more and more distributed to fill the gap between vertical aerial images and mobile mapping systems. Different systems are on the market. For some applications, like texture mapping, precise orientation data are required. One point is the stable interior orientation, which can be achieved by stable camera systems, the other a precise exterior orientation. A sufficient exterior orientation can be achieved by a large effort in direct sensor orientation, whereas minor errors in the angles have a larger effect than in vertical imagery. The more appropriate approach is by determine the precise orientation parameters by photogrammetric methods using an adapted aerial triangulation. Due to the different points of view towards the object the traditional aerotriangulation matching tools fail, as they produce a bunch of blunders and require a lot of manual work to achieve a sufficient solution. In this paper some approaches are discussed and results are presented for the most promising approaches. We describe a single step approach with an aerotriangulation using all available images; a two step approach with an aerotriangulation only of the vertical images plus a mathematical transformation of the oblique images using the oblique cameras excentricity; and finally the extended functional model for a bundle block adjustment considering the mechanical connection between vertical and oblique images. Beside accuracy also other aspects like efficiency and required manual work have to be considered.

    Background Approaches to measuring recovery orientation are needed, particularly for programs that may struggle with implementing recovery-oriented treatment. Objective A mixed methods comparative study was conducted to explore effective approaches to measuring recovery orientation of Assertive Community Treatment (ACT) teams. Design Two ACT teams exhibiting high and low recovery orientation were compared using surveys, treatment plan ratings, diaries of treatment visits, and team-leader-reported treatment control mechanisms. Results The recovery-oriented team differed on one survey measure (higher expectations for consumer recovery), treatment planning (greater consumer involvement and goal-directed content), and use of control mechanisms (less use of representative payee, agency-held lease, daily medication delivery, and family involvement). Staff and consumer diaries showed the most consistent differences (e.g., conveying hope and choice) and were the least susceptible to observer bias, but had the lowest response rates. Conclusions Several practices differentiate recovery orientation on ACT teams, and a mixed-methods assessment approach is feasible. PMID:23690285

    Full Text Available Classical statistical mechanics of the molecular optics theory proposed by Buckingham [A. D. Buckingham and J. A. Pople, Proc. Phys. Soc. A 68, 905 (1955] has been extended to describe the field induced molecular orientational polarization effects on nonlinear optics. In this paper, we present the generalized molecular orientational nonlinear optical processes (MONLO through the calculation of the classical orientational averaging using the Boltzmann type time-averaged orientational interaction energy in the randomly oriented molecular system under the influence of applied electric fields. The focal points of the calculation are (1 the derivation of rigorous tensorial components of the effective molecular hyperpolarizabilities, (2 the molecular orientational polarizations and the electronic polarizations including the well-known third-order dc polarization, dc electric field induced Kerr effect (dc Kerr effect, optical Kerr effect (OKE, dc electric field induced second harmonic generation (EFISH, degenerate four wave mixing (DFWM and third harmonic generation (THG. We also present some of the new predictive MONLO processes. For second-order MONLO, second-order optical rectification (SOR, Pockels effect and difference frequency generation (DFG are described in terms of the anisotropic coefficients of first hyperpolarizability. And, for third-order MONLO, third-order optical rectification (TOR, dc electric field induced difference frequency generation (EFIDFG and pump-probe transmission are presented.

  10. Neurobiology of Gender Identity and Sexual Orientation.

    Roselli, Charles E

    2017-12-06

    Sexual identity and sexual orientation are independent components of a person's sexual identity. These dimensions are most often in harmony with each other and with an individual's genital sex, but not always. This review discusses the relationship of sexual identity and sexual orientation to prenatal factors that act to shape the development of the brain and the expression of sexual behaviors in animals and humans. One major influence discussed relates to organizational effects that the early hormone environment exerts on both gender identity and sexual orientation. Evidence that gender identity and sexual orientation are masculinized by prenatal exposure to testosterone and feminized in it absence is drawn from basic research in animals, correlations of biometric indices of androgen exposure and studies of clinical conditions associated with disorders in sexual development. There are, however, important exceptions to this theory that have yet to be resolved. Family and twin studies indicate that genes play a role, but no specific candidate genes have been identified. Evidence that relates to the number of older brothers implicates maternal immune responses as a contributing factor for male sexual orientation. It remains speculative how these influences might relate to each other and interact with postnatal socialization. Nonetheless, despite the many challenges to research in this area, existing empirical evidence makes it clear that there is a significant biological contribution to the development of an individual's sexual identity and sexual orientation.

  11. Selective enhancement of orientation tuning before saccades.

    Ohl, Sven; Kuper, Clara; Rolfs, Martin

    2017-11-01

    Saccadic eye movements cause a rapid sweep of the visual image across the retina and bring the saccade's target into high-acuity foveal vision. Even before saccade onset, visual processing is selectively prioritized at the saccade target. To determine how this presaccadic attention shift exerts its influence on visual selection, we compare the dynamics of perceptual tuning curves before movement onset at the saccade target and in the opposite hemifield. Participants monitored a 30-Hz sequence of randomly oriented gratings for a target orientation. Combining a reverse correlation technique previously used to study orientation tuning in neurons and general additive mixed modeling, we found that perceptual reports were tuned to the target orientation. The gain of orientation tuning increased markedly within the last 100 ms before saccade onset. In addition, we observed finer orientation tuning right before saccade onset. This increase in gain and tuning occurred at the saccade target location and was not observed at the incongruent location in the opposite hemifield. The present findings suggest, therefore, that presaccadic attention exerts its influence on vision in a spatially and feature-selective manner, enhancing performance and sharpening feature tuning at the future gaze location before the eyes start moving.

  12. Correlation between grain orientation and the shade of color etching

    Szabo, Peter J.; Kardos, I.

    2010-01-01

    Color etching is an extremely effective metallographic technique not only for making grains well visible, but also for making them distinguishable for automated image analyzers. During color etching, a thin film is formed on the surface of the specimen. The thickness of this layer is in the order of magnitude of the visible light and since both the metal-film boundary and the film surface reflect light, an interference occurs. A wavelength-component of the white line is eliminated and its complementary color will be seen on the surface. As the thickness changes, the colors also change grain by grain. The thickness of the film is dependent on several factors, mostly on the type of the phase. However, different color shades can be observed on the surfaces of single phase materials, which phenomenon is caused by the different crystallographic orientations of the grains. This paper shows a combined color etching electron backscatter diffraction (EBSD) investigation of cast iron. An area of the surface of a gray cast iron specimen was etched. Colors were characterized by their luminescence and their red, green and blue intensity. An EBSD orientation map was taken from the same area and the orientations of the individual grains were determined. Results showed that a strong correlation was found between the luminescence and the R, G, B intensity of the color and the angle between the specimen normal and the direction, while such correlation was not observed between the color parameters and the and directions, respectively. This indicates that film thickness is sensitive to the direction of the crystal.

  13. Slant-tilt: the visual encoding of surface orientation.

    Science.gov (United States)

    Stevens, K A

    1983-01-01

    A specific form for the internal representation of local surface orientation is proposed, which is similar to Gibson's (1950) "amount and direction of slant". Slant amount is usually quantified by the angle sigma between the surface normal and the line of sight (0 degrees less than or equal to sigma less than or equal to 90 degrees). Slant direction corresponds to the direction of the gradient of distance from the viewer to the surface, and may be defined by the image direction tau to which the surface normal would project (0 degrees less than or equal to tau less than or equal to 360 degrees). Since the direction of slant is specified by the tilt of the projected surface normal, it is referred to as surface tilt (Stevens, 1979; Marr, 1982). The two degrees of freedom of orientation are therefore quantified by slant, an angle measured perpendicular to the image plane, and tilt, an angle measured in the image plane. The slant-tilt form provides several computational advantages relative to some other proposals and is consistent with various psychological phenomena. Slant might be encoded by various means, e.g. by the cosine of the angle, by the tangent, or linearly by the angle itself. Experimental results are reported that suggest that slant is encoded by an internal parameter that varies linearly with slant angle, with resolution of roughly one part in 100. Thus we propose that surface orientation is encoded in human vision by two quantities, one varying linearly with slant angle, the other varying linearly with tilt angle.

  15. From Orientalism to neo-Orientalism: Early and contemporary constructions of Islam and the Muslim world

    Directory of Open Access Journals (Sweden)

    Salim Kerboua

    2016-07-01

    Full Text Available The concept of Orientalism has been widely dealt with in the humanities and social sciences. It helps explain a peculiar construction of the Arab-Muslim world. Orientalism has operated in various historical paradigms but has always emphasised specific Western constructions of the Orient. Nowadays, the concept has metamorphosed to refer to new constructions of the Orient. New representations of Islam and the Muslim world are dominating the Western public space. The aim of this paper is twofold. It explores the historical development and paradigmatic shifts that have affected the concept of Orientalism. It then suggests that a neo-Orientalism has recently emerged, is less territorialised and operating within a new paradigm. It holds a new ideologically motivated agenda, constructs new objects, and feeds the social phenomenon called Islamophobia.

    The use of fiber reinforced materials such as randomly-oriented strands has grown in recent years, especially for manufacturing of aerospace composite structures. This growth is mainly due to their advantageous properties: they are lighter and more resistant to corrosion when compared to metals and are more easily shaped than continuous fiber composites. The resistance and stiffness of these materials are directly related to their fiber orientation. Thus, efficient approaches to assess their fiber orientation are in demand. In this paper, a non-destructive evaluation method is applied to assess the fiber orientation on laminates reinforced with randomly-oriented strands. More specifically, a method called pulsed thermal ellipsometry combined with an artificial neural network, a machine learning technique, is used in order to estimate the fiber orientation on the surface of inspected parts. Results showed that the method can be potentially used to inspect large areas with good accuracy and speed.

    Motivation deficits are common in several disorders including schizophrenia, and are an important factor in both functioning and treatment adherence. Self-Determination Theory (SDT), a leading macro-theory of motivation, has contributed a number of insights into how motivation is impaired in schizophrenia. Nonetheless, self-report measures of motivation appropriate for people with severe mental illness (including those that emphasize SDT) are generally lacking in the literature. To fill this gap, we adapted and abbreviated the well-validated General Causality Orientation Scale for use with people with schizophrenia and with other severe mental disorders (GCOS-clinical populations; GCOS-CP). In Study 1, we tested the similarity of our measure to the existing GCOS (using a college sample) and then validated this new measure in a schizophrenia and healthy control sample (Study 2). Results from Study 1 (N=360) indicated that the GCOS-CP was psychometrically similar to the original GCOS and provided good convergent and discriminant validity. In Study 2, the GCOS-CP was given to individuals with (N=44) and without schizophrenia (N=42). In line with both laboratory-based and observer-based research, people with schizophrenia showed lower motivational autonomy and higher impersonal/amotivated orientations. Additional applications of the GCOS-CP are discussed. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    2002-07-01

    In this paper, we investigate the relativistic beaming effects in a well-defined sample of core- dominated quasars using the correlation between the relative prominence of the core with respect to the extended emission (defined as the ratio of the core- to the lobe- flux density measured in the rest frame of the source) and the projected linear size as an indicator of relativistic beaming and source orientation. Based on the orientation-dependent relativistic beaming and unification paradigm for high luminosity sources in which the Fanaroff-Riley class-ll radio galaxies form the unbeamed parent population of both the lobe- and core-dominated quasars which are expected to lie at successively smaller angles to the line of sight, we find that the flows in the cores of these core-dominated quasars are highly relativistic, with optimum bulk Lorentz factor, γ opt ∼6-16, and also highly anisotropic, with an average viewing angle, ∼ 9 deg. - 16 deg. Furthermore, the largest boosting occurs within a critical cone angle of ∼ 4 deg. - 10 deg. The results suggest that relativistic bulk flow appears to extend to kilo-parsec scales in these sources.

    2016-06-01

    Full Text Available In this paper, a methodology for the calculation of rough exterior orientation (EO parameters of multiple large-scale overlapping oblique aerial images, in the case that GPS/INS information is not available (e.g., for old datasets, is presented. It consists of five main steps; (a the determination of the overlapping image pairs and the single image in which four ground control points have to be measured; (b the computation of the transformation parameters from every image to the coordinate reference system; (c the rough estimation of the camera interior orientation parameters; (d the estimation of the true horizon line and the nadir point of each image; (e the calculation of the rough EO parameters of each image. A developed software suite implementing the proposed methodology is tested using a set of UAV multi-perspective oblique aerial images. Several tests are performed for the assessment of the errors and show that the estimated EO parameters can be used either as initial approximations for a bundle adjustment procedure or as rough georeferencing information for several applications, like 3D modelling, even by non-photogrammetrists, because of the minimal user intervention needed. Finally, comparisons with a commercial software are made, in terms of automation and correctness of the computed EO parameters.

Using Delaunay triangulation as well as classic distribution analyses, it demonstrates that landscape boundaries articulated already established use......-patterns close to roads, but also intercepted the central lines of movement and conflicted with previous ways of organizing the landscape. This development is interpreted as a different form of large-scale landholding, in which livestock possibly played a dominant role and boundaries were used to confiscate land...... in the zones bordering suitable pastures. This situation shows obvious parallels with southern Britain centuries earlier.

  5. Line broadening by focusing

    Brito, A.L. de; Jabs, A.

    1983-01-01

    It is pointed out that the spectral width of a quasi-monochromatic light beam broadens when the beam is focused. A quantitative formula for this broadening is derived from classical wave theory. The effect is shown to explain some experiments on laser beams done by E. Panarella which that author has explained under the ad-hoc hypothesis that the frequency of the photons changes along with the intensity of the light beam. The line broadening by focusing might also contribute to gas ionization by incident light when the ionization potential is well above the mean photon energy. Some remarks are made on some direct applications of the Heisenberg relations in comparison with our treatment. (Author) [pt

    Based on observational analyses and on-site ground and aerial damage surveys, this work aims to reveal the weather phenomena-especially the wind situation-when Oriental Star capsized in the Yangtze River on June 1, 2015. Results demonstrate that the cruise ship capsized when it encountered strong winds at speeds of at least 31 m s -1 near the apex of a bow echo embedded in a squall line. As suggested by the fallen trees within a 2-km radius around the wreck location, such strong winds were likely caused by microburst straight-line wind and/or embedded small vortices, rather than tornadoes.

    The geometry of distributions of the polarization of light in conoscopic patterns of planar oriented nematic and cholesteric liquid crystal (LC) cells is described in terms of the polarization singularities including C-points (points of circular polarization) and L lines (lines of linear polarization). Conditions for the formation of polarization singularities ( C-points) in an ensemble of conoscopic patterns parametrized by the polarization azimuth and ellipticity of the incident light wave have been studied. A characteristic feature of these conditions is selectivity with respect to the polarization parameters of the incident light wave. The polarization azimuth and ellipticity are determining parameters for nematic and cholesteric LC cells, respectively.

    Much recent research work discusses the transformation between differentprocess modelling languages. This work, however, is mainly focussed on specific processmodelling languages, and thus the general reusability of the applied transformationconcepts is rather limited. In this paper, we aim...... to abstract from concrete transformationstrategies by distinguishing two major paradigms for process modelling languages:block-oriented languages (such as BPEL and BPML) and graph-oriented languages(such as EPCs and YAWL). The contribution of this paper are generic strategiesfor transforming from block......-oriented process languages to graph-oriented languages,and vice versa. We also present two case studies of applying our strategies....

    There have been literatures that have focused limited topics of teaching material, educational robots etc. There have been also literatures to teach control engineering in the robotics. It seems to be no reports that have discussed the framework, curriculum for system control engineering education. The present paper describes the design of curriculum for system control engineering of technical college in Japan. The feature of the curriculum is line tracer oriented. In the proposed curriculum, basic line tracers are developed to high technology tracers as grade in college advanced. Basic tracers are developed with simple logic devices. High technology tracers are controlled by microcomputers, such as H8. Students can develop line tracers based on the course programme, and it is expected that students will be more aggressive in learning technology. The paper introduces basic concept of a line tracer oriented curriculum and shows educational perspective for embedded technology. The proposed idea in the paper can be applied to other education sectors.

Activity of Muscles during clenching will be least, when the occlusal plane is made parallel to plane of lost natural teeth. Conventionally the ala-tragus line (Camper’s plane) is used as a guide for assessment of t...

  12. Magnetic compass orientation in the European eel.

    Directory of Open Access Journals (Sweden)

    Caroline M F Durif

    Full Text Available European eel migrate from freshwater or coastal habitats throughout Europe to their spawning grounds in the Sargasso Sea. However, their route (~ 6000 km and orientation mechanisms are unknown. Several attempts have been made to prove the existence of magnetoreception in Anguilla sp., but none of these studies have demonstrated magnetic compass orientation in earth-strength magnetic field intensities. We tested eels in four altered magnetic field conditions where magnetic North was set at geographic North, South, East, or West. Eels oriented in a manner that was related to the tank in which they were housed before the test. At lower temperature (under 12°C, their orientation relative to magnetic North corresponded to the direction of their displacement from the holding tank. At higher temperatures (12-17°C, eels showed bimodal orientation along an axis perpendicular to the axis of their displacement. These temperature-related shifts in orientation may be linked to the changes in behavior that occur between the warm season (during which eels are foraging and the colder fall and winter (during which eels undertake their migrations. These observations support the conclusion that 1. eels have a magnetic compass, and 2. they use this sense to orient in a direction that they have registered moments before they are displaced. The adaptive advantage of having a magnetic compass and learning the direction in which they have been displaced becomes clear when set in the context of the eel's seaward migration. For example, if their migration is halted or blocked, as it is the case when environmental conditions become unfavorable or when they encounter a barrier, eels would be able to resume their movements along their old bearing when conditions become favorable again or when they pass by the barrier.

    Full Text Available The purpose of this paper is to provide a review of the main issues surrounding the concept of market orientation applied in the context of higher education. Considering the important changes taking place in this sector, a strong willingness of universities to adopt marketing concepts can be noticed. The paper seeks to provide a retrospect on this process, starting with the incorporation of marketing in higher education, and moving on to its implementation, which has come to be known as market orientation. Following a stream of the most relevant literature in the field, we present definitions of the main concepts, and integrate them in the education context, with the purpose of establishing the relevance and importance of market orientation for achieving a sustainable competitive advantage and higher institutional performance. The paper does not aim at providing an exhaustive literature review, but rather at presenting the main elements that define a market orientation, and at supporting its implementation, by outlining the significant benefits that could follow. While theoretical by nature, this research contributes to the body of literature in the field, through closely examining the conceptualization and operationalization of market orientation, and also providing the fundamental components that define the concept and help its implementation. Furthermore, the paper provides practitioners with a number of suggested research directions, which could potentially help improve educational institutions’ activity, while also contributing to a better understanding of the concept, and to building richer theories in the field of marketing education. Given that the marketing literature in Romania has mostly overlooked market orientation, both this paper, and all following research in this area will prove to be significant for education managers and researchers alike, promoting the importance and significance of relevant knowledge, and encouraging a

    Full Text Available The problem of protection of a three-phase four-wire distribution network (DEN with a voltage of 0.4 kV from the interruption of electric power lines is considered. On the basis of the analysis of the values of complex resistances of interpersonal sections of the main line of the network, criteria are proposed that allow detecting critical situations associated with discontinuities in power transmission lines. Using these criteria makes it possible to localize the places of breaks of phase and neutral wires. Mathematical models and methods that are used to evaluate the complex resistances of interpersonal sections of a three-phase network are briefly considered. The obtained results are oriented for use in the automated system of electricity control and accounting (ASMAE.

    The present study was carried out in order to examine the radiosensitivity of malignant pleural mesothelioma cell lines. Cell kinetics, radiation-induced delay of the cell cycle and DNA ploidy of the cell lines were also determined. For comparison an HeLa and a human foetal fibroblast cell line were simultaneously explored. Six previously cytogenetically and histologically characterized mesothelioma tumor cell lines were applied. A rapid tiazolyl blue microtiter (MTT) assay was used to analyze radiosensitivity and cell kinetics and DNA ploidy of the cultured cells were determined by flow cytometry. The survival fraction after a dose of 2 Gy (SF2), parameters α and β of the linear quadratic model (LQ-model) and mean inactivation dose (D MID ) were also estimated. The DNA index of four cell lines equaled 1.0 and two cell lines equaled 1.5 and 1.6. Different mesothelioma cell lines showed a great variation in radiosensitivity. Mean survival fraction after a radiation dose of 2 Gy (SF2) was 0.60 and ranged from 0.36 to 0.81 and mean α value was 0.26 (range 0.48-0.083). The SF2 of the most sensitive diploid mesothelioma cell line was 0.36: Less than that of the foetal fibroblast cell line (0.49). The survival fractions (0.81 and 0.74) of the two most resistant cell lines, which also were aneuploid, were equal to that of the HeLa cell line (0.78). The α/β ratios of the most sensitive cell lines were almost an order of magnitude greater than those of the two most resistant cell lines. Radiation-induced delay of the most resistant aneuploid cell line was similar to that of HeLa cells but in the most sensitive (diploid cells) there was practically no entry into the G1 phase following the 2 Gy radiation dose during 36 h.

    1 - Description of program or function: INTERP is a free format data interpretation subroutine system for lexical analysis. The system is flexible, easy to use, small, and efficient and simplifies the development of a problem oriented language (POL) as well as any other translation preprocessor for an application program. INTERP is currently being used to interpret POL translators for both engineering analysis codes and utility programs. The application callable part of the INTERP subroutine system consists of the configuration routines, the interrogation routines, the logical testing functions, the utility routines, the advanced operations routines, and a string handling library. INTERP processes textual information in the form of strings, which are a primary means of data exchange between INTERP and the application program. The INTERP system can be configured to read data directly from a file opened by the application program or the application program. The INTERP system can be configured to read data directly from a file opened by the application program or the application program may read the data file directly and pass the data to the INTERP system by means of a utility routine. 2 - Method of solution: INTERP is a lexical analyzer which examines a data line with no prior knowledge of what it contains and informs the application program of what was found. Each data line typically consists of a collection of special characters and tokens. A token is defined to be an identifiable unit of information. Each new data line is loaded into an internal line buffer and examined one character at a time until a complete token is read. At this time control is returned to the application program which uses the INTERP logical testing functions to identify the token.Once the identification is made, INTERP continues processing the data line until it reaches the end-of-line. INTERP is then given a new line and the process is repeated. INTERP recognizes three classes of tokens

    Research purpose: The principal objective of the study was the construction of a normative scale to measure the positive states associated with appreciative ability and to relate it to a scale of entrepreneurial orientation. A secondary objective was to determine whether there was a statistically significant relationship between the measures of the constructs and the biographical variables of gender and culture. Motivation: As appreciative ability is a relatively new construct and no instrument exists for measuring the positive states emanating from this construct, it was decided to develop such an instrument and to relate it to entrepreneurship orientation. Research design, approach and method: The primary data were obtained by means of the newly designed instrument, the Positive States Questionnaire and the Entrepreneurship Orientation Questionnaire. A convenience sample of 210 second year commerce students was drawn. Main findings: From a principal factor analysis applied to the two instruments, two factors each were obtained. A significantly high correlation was found, indicating a strong relationship between entrepreneurship orientation and the positive states. No significant differences were found between gender or population in the entrepreneurship orientation and positive states measures. Practical/managerial implications: The study produced an instrument with highly acceptable metrical properties which may be used in future studies and for entrepreneurship development. Contribution/value-add: The results of the study suggest that positive states are invaluable attributes for the entrepreneur and should be explored in the assessment and development of entrepreneurs.

    Clinical impressions suggest a different sexual profile between individuals with and without Autism Spectrum Disorder (ASD). Little is presently known about the demographics of sexual orientation in ASD. Sexual Orientation was surveyed using the Sell Scale of Sexual Orientation in an international online sample of individuals with ASD (N = 309, M = 90, F= 219), aged (M = 32.30 years, SD = 11.93) and this was compared to sexual orientation of typically-developing individuals (N = 310, M = 84, F= 226), aged (M = 29.82 years, SD = 11.85). Findings suggested that sexual orientation was contingent on diagnosis (N = 570, χ 2 (9) =104.05, P Autism Res 2018, 11: 133-141. © 2017 International Society for Autism Research, Wiley Periodicals, Inc. Research suggests that individuals with Autism Spectrum Disorder (ASD) report increased homosexuality, bisexuality, and asexuality, but decreased heterosexuality. It is important to increase awareness about increased non-heterosexuality in ASD among autistic populations, medical professionals and care-takers, so as to provide specialized care, if needed and increase support and inclusion for non-heterosexual autistic individuals. © 2017 International Society for Autism Research, Wiley Periodicals, Inc.

  19. Minireview: Hormones and Human Sexual Orientation

    Many people believe that sexual orientation (homosexuality vs. heterosexuality) is determined by education and social constraints. There are, however, a large number of studies indicating that prenatal factors have an important influence on this critical feature of human sexuality. Sexual orientation is a sexually differentiated trait (over 90% of men are attracted to women and vice versa). In animals and men, many sexually differentiated characteristics are organized during early life by sex steroids, and one can wonder whether the same mechanism also affects human sexual orientation. Two types of evidence support this notion. First, multiple sexually differentiated behavioral, physiological, or even morphological traits are significantly different in homosexual and heterosexual populations. Because some of these traits are known to be organized by prenatal steroids, including testosterone, these differences suggest that homosexual subjects were, on average, exposed to atypical endocrine conditions during development. Second, clinical conditions associated with significant endocrine changes during embryonic life often result in an increased incidence of homosexuality. It seems therefore that the prenatal endocrine environment has a significant influence on human sexual orientation but a large fraction of the variance in this behavioral characteristic remains unexplained to date. Genetic differences affecting behavior either in a direct manner or by changing embryonic hormone secretion or action may also be involved. How these biological prenatal factors interact with postnatal social factors to determine life-long sexual orientation remains to be determined. PMID:21693676

    The long range position and orientation tracking system (LRPOTS) will consist of two measurement pods, a VME-based computer system, and a detector array. The system is used to measure the position and orientation of a target that may be attached to a robotic arm, teleoperated manipulator, or autonomous vehicle. The pods have been designed to be mounted in the man-ways of the domes of the Fernald K-65 waste silos. Each pod has two laser scanner subsystems as well as lights and camera systems. One of the laser scanners will be oriented to scan in the pan direction, the other in the tilt direction. As the lasers scan across the detector array, the angles of incidence with each detector are recorded. Combining measurements from each of the four lasers yields sufficient data for a closed-form solution of the transform describing the location and orientation of the Content Mobilization System (CMS). Redundant detectors will be placed on the CMS to accommodate occlusions, to provide improved measurement accuracy, and to determine the CMS orientation.
