One of the biggest problem areas in relation to Computer Assisted Pronunciation Training (CAPT) applications, designed for Second Language Learning (SLL), has been that of feedback. As with human teachers, the ultimate goal of CAPT is to provide instantaneous, individualized feedback to the user on the overall quality of the pronunciation made. Attempts at accomplishing this goal have seen the ...

Recirculating, energy–recovering linacs can be used as driver accelerators for high power FELs. Instabilitieswhich arise from fluctuations of the cavity fields are investigated. Energy changes can cause beam loss on apertures, or, when coupled toM56, phase oscillations. Both effects change the beam induced voltage in the cavities and can lead to unstable variations of the accelerating field. An...

Introduction: Feedback is very important in education and can help quality in the training process and orient the trainees in clinical contexts. This study aimed to assess the residents’ points of view about feedback in clinical education at Shiraz University of Medical Sciences.Methods: The sample of this study included 170 medical residents attending medical workshops in Shiraz University of ...

Yu-Fen Yang, National Yunlin University of Science and Technology Wen-Ting Meng, National Yunlin University of Science and Technology Oftentimes, college students who learn English as a Foreign Language (EFL) provide their peers with incorrect and misleading feedback during text revision. To improve the effectiveness of peer feedback, this study examined the degree to which online feedback trai...

The third-generation synchrotron radiation (SR) facilities are storage ring-based facilities with many insertion devices and photon beamlines, and have low injection beam power, but extremely high stored beam power. The fourth-generation X-ray free electron laser (FEL) facilities are based on an electron Linac with a long undulator and have high injection beam power. Due to its electron and pho...

In this paper we introduce a system for providing automatically generated corrective feedback on pronunciation errors in Dutch, Dutch-CAPT. We describe the architecture of the system paying particular attention to the rationale behind it, to the performance of the error detection algorithm and its relationship to the effectiveness of the corrective feedback provided. It appears that although th...

Exponential growth and superradiance regimes in a high-gain free electron laser (FEL) are studied in this paper for both a seeded FEL and a Self-Amplified Spontaneous Emission (SASE) FEL. The results are compared to the earlier superrdaince theory and the recent experimental observation. The influence of an initial energy chirp along the electron bunch on the superradiance mode is explored for ...
