    David Frankel\u27s The Devil Wears Prada (2006) is an American film based on Lauren Weisberger\u27s 2003 best-selling novel of the same name. Set mainly in the office of the fictional Runway fashion magazine, this film focuses on the agon between a young woman and the powerful, imperious female editor-in-chief of the magazine she works as the second assistant to. The young woman, the protagonist of the film, has little knowledge of fashion; she gets the job as a mere stopgap until she finds a better one in journalism. As soon as she starts working at Runway, she feels herself thrown into an alien, uneveryday world. Moreover, she is tested through a series of tough, unreasonable ordeals and humiliations by the editor-in-chief and, in the process, undergoes a metamorphosis

    A design strategy for the combined power filter for a three-phase twelve-pulse thyristor rectifier is proposed. The shunt passive filter, which can minimize the output voltage of the series active filter, is designed and tested in a prototype model. A specially designed shunt passive filter makes it possible to reduce the required rating of the series active filter to 60% compared with a conventional shunt passive filter </p

    Analysis and design of a DC voltage-controlled static VAr compensator using quad-series voltage-source inverters

    This paper presents a DC voltage-controlled static VAr compensator (SVC) using quad-series voltage-source non-PWM inverters. The SVC consists of four three-phase voltage-source inverters having a common DC capacitor and four three-phase transformers, the primary windings of which are connected in series with each other. Although each inverter outputs a square wave voltage, the synthesized AC voltage of the SVC has a 24-step waveshape. This results not only in a great reduction of harmonic currents and DC voltage ripples but also in less switching and snubbing losses. This paper develops the analysis of the transient response and the resonance between the AC reactors and the DC capacitor, with the focus on practical use. Experimental results obtained from a 10-kVA laboratory system are shown to agree well with the analytical results, thus verifying the analysis and leading to the design of DC capacitance value </p

    発達障害の臨床的に類似した認知・行動特性に関する判別的アセスメント : 高精度で個別化された理解と支援に向けて

    Developmental disabilities, including learning difficulties (LD), attention-deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD), are syndromes that have unclear etiologies and are diagnosed on the basis of their clinical features. Developmental disabilities show high rates of comorbidity, resulting in similar clinical pictures in many cases. However, these similar clinical pictures may be based on different underlying factors that can be determined by microscopic observation or tests. In this study, differential assessments that were based on research using laboratory-based cognitive tasks were proposed for differentiating between the underlying factors that contribute to similar clinical pictures of developmental disabilities. These factors, which should be treated using a different therapeutic approach, include the following: 1) error monitoring (the primary deficit typically observed in LD) and mental effort (typically observed in ADHD) with respect to careless mistakes; 2) response decision (typically observed in ADHD) and motor inhibition (typically observed in oppositional defiant disorder/conduct disorder) with respect to behavioural inhibition and 3) preattentive processing (typically observed in LD) and weak central coherence (typically observed in ASD) with respect to global perception. These differential assessments may provide detailed and individualized understanding and support to individuals with developmental disabilities and critical information for the differential diagnosis of developmental disabilities

    Turbine Characteristics of Wave Energy Conversion Device for Extraction Power Using Breaking Waves

    A new type of wave energy converter which harnesses electricity from onshore breaking waves has been studied at Okinawa Institute of Science and Technology Graduate University (OIST) since 2014. This concept has been demonstrated at a coral beach on the Maldives since 2018. Wave energy conversion is possible when waves approaching the shore steepen due to decreased water depth resulting in wave breaks near the surface. A steepened wave reaches the critical velocity of 4~6 m/sec shoreward before it breaks. A rotating blade takes advantage of this breaking phenomenon to convert the wave energy into electricity. The work presented here includes an experimental and numerical investigation of a prototype model of the wave energy converter. The turbine having five blades of variable chord lengths, twist angles, and constant thickness profile from hub to tip was simulated under similar flow as well as testing conditions, to predict the turbine performance. A commercial computational fluid dynamic tool SolidWorks Flow Simulation 2018 was used for the simulations at various rotation speeds with a uniform inlet velocity. The modified k-ε with a two-scale wall function turbulence closure model was selected. The validation performed for different test cases showed that the present computational results match in good agreement with the experimental results. Additionally, details performance of the turbine running, and generator characteristics have been reported in this paper

    Development of a non-intrusive and efficient flow monitoring technique : The space-time image Velocimetry (STIV)

    Get PDF
    A novel image analysis technique for measuring river surface flow is proposed. When we assume that the brightness distribution of river surface image is convected with the surface velocity, a space-time image for a searching line set parallel to the main flow would indicate velocity information as its image orientation. The new technique, the space-time image velocimetry (STIV), is capable to measure the orientation angle of the pattern using the eigenvalue analysis of the local space-time image. The performance of STIV is compared with the other image analysis technique, the large-scale particle image velocimetry (LSPIV), previously proposed by the authors and it is shown that STIV is an alternative image analysis method for measuring streamwise velocity distributions efficiently
