语言接口理论对口语教学的启示

在非目标语环境中学习第二语言,经常会出现口语发展滞后的情况."无接口"观点认为这是因为"学习的知识"无法转化为"习得的知识"造成的."有接口"观点认为这两种知识通过一定形式的操练是可以互通的.本文将这两种理论加以比较,分析二语学习者口语发展滞后的原因,并探讨了实现互通、发展口语能力的一些切实可行的方法.

A natural language user interface for fuzzy scope queries

This paper presents a two-agent framework to build a natural language query interface for IC information system, focusing more on scope queries in a single English sentence. The first agent, parsing agent, syntactically processes and semantically interprets natural language sentence to construct a fuzzy structured query language (SQL) statement. The second agent, defuzzifying agent, defuzzifies the imprecise part of the fuzzy SQL statement into its equivalent executable precise SQL statement based on fuzzy rules. The first agent can also actively ask the user some necessary questions when it manages to disambiguate the vague retrieval requirements. The adaptive defuzzification approach employed in the defuzzifying agent is discussed in detail. A prototype interface has been implemented to demonstrate the effectiveness.

Java的多线程技术在网上教学中的应用

首行用继承Thread类和实现Runnable接口两种不同的方法分别创建了安全检查线程和网上教学课件线程，然后利用Java多线程技术中线程的启动使这两个线能够并行运行，再利用线程的挂起和唤醒使它们相互制约，从而实在保证课件独立性的前提下，提高了网上教学的安全性。     

SSC： Gesture-based game for initial dementia examination

INTRODUCTION Dementia is becoming a big problem in modern life, and particularly, it takes place more frequently in mental job group and the elderly. Today, more than 20 million people in the world catch this disease (Francis et al., 1999; Almkvist et al., 1998). So how to detect underlying dementia and take preventive measure is critical for both the doctors and their patients. People with dementia always behave slowly and their memory decreases with the development of the disease. Curr…

水下声散射一致性时域有限差分法的并行算法

In this work, we treat scattering objects, water, surface and bottom in a truly unified manner in a parallel finite-difference time-domain (FDTD) scheme, which is suitable for distributed parallel computing in a message passing interface(MPI) programming environment. The algorithm is implemented on a cluster-based high performance computer system.Parallel computation is performed with different division methods in 2D and 3D situations. Based on analysis of main factorsaffecting the speedup rate and parallel efficiency, data communication is reduced by selecting a suitable scheme of task division.A desirable scheme is recommended, giving a higher speedup rate and better efficiency. The results indicate that the unifiedparallel FDTD algorithm provides a solution to the numerical computation of acoustic scattering.
