Abstract:

AbstractIt has been widely claimed that Kanji is one of the most difficult aspects of Japanese language learning for learners with alphabetic language backgrounds. There are various techniques devised by teachers to teach Kanji effectively. However, given variables such as individual differences, none of these techniques can be a single perfect technique. In this paper, how learners process Kanji is analysed, then based on the findings of the analysis, techniques for teaching Kanji are classified into four categories for developing learners’ proper processing skills. The four categories are: 1

Abstract:

Most diagnostic ultrasonic imaging systems perform fixed focusing on transmit and dynamic focusing on receive. Such systems suffer from image quality degradation at depths away from the transmit focal zone. Several dynamic transmit focusing techniques have been previously investigated. Among them, a filter-based, retrospective focusing technique was proposed to increase the length of the transmit focal zone. In this paper, the filter-based technique is extended from dynamic receive focusing to fixed receive focusing. It is shown that the filtering technique with fixed receive focusing can achi

Abstract:

The successful use is reported of a particle-swarm optimization algorithm to design a focusing, multi-channel neutron guide for the measurement of millimetre- and sub-millimetre-sized samples. For a 5 Å incident neutron wavelength on an IN5-type instrument, this results in a ninefold gain in the peak neutron count rate, and around an eightfold average gain in the count rate over the crucial 3–6 Å wavelength range, averaged over a 2 × 2 mm sample. A particle swarm method and a genetic algorithm were compared for simple neutron flux maximization, and the particle swarm was found to be faster for

Abstract:

In this work, we analyze the effect of predistortion techniques on the focusing profile of Fresnel Zone Plates (FZPs) in ultrasound applications. This novel predistortion method is based on either increasing or decreasing the width of some of the FZP Fresnel rings by a certain amount. We investigate how the magnitude of the predistortion, as well as the number and location of the predistorted rings, influences the lens focusing profile. This focusing profile can be affected in different ways depending on the area of the lens where the predistortion is applied. It is shown that when the inner a

Abstract:

Prestack depth migration still suffers from the problems associated with building appropriate velocity models. The two main after‐migration, before‐stack velocity analysis techniques currently used, depth focusing and residual moveout correction, have found good use in many applications but have also shown their limitations in the case of very complex structures. To address this issue, we have extended the residual moveout analysis technique to the general case of heterogeneous velocity fields and steep dips, while keeping the algorithm robust enough to be of practical use on real data.

Abstract:

Ultrasonic phased array inspection has been paid a great attention in ultrasonic nondestructive evaluation since it can provide a benefit of focusing and/or steering ultrasonic beams. A time reversal technique is claimed to be very robust to focus beams through inhomogeneous media, using the phased array transducers. In this paper, the performance and limitations of a D.O.R.T. method, which is one of the time reversal techniques, is considered based on the experimental studies. In addition, a variation of the D.O.R.T, namely a pre-focused D.O.R.T., is proposed in order to overcome the limitati

The inspection of austenitic and dissimilar welds using ultrasound demands for sophisticated testing techniques. The application of reconstruction methods like the Synthetic Aperture Focusing Technique (SAFT) on the measurement results provides an appropriate approach for defect characterization and sizing. Nevertheless, the reconstruction algorithm has to consider the aniso-tropic wave propagation inside the inhomogeneous weld material. In recent years the detection of transverse cracks has become increasingly important for ensuring the structural integrity of pipes in the primary circuit of

We analyze the situation when observations in the original sample are independent random variables with identical distributions, and response or its lack is modeled by a random mechanism which is independent of observations. In particular, we point out to problems that arise when the standard Rubin estimate of the multiple imputation variance estimator is used. A possible improvement of this popular estimator is indicated. The star
