Improving Writing Skills of Thai EFL Students by Recognition of and Compensation for Factors of L 1 to L2 Negative Transfer

In this study, we examined the likelihood of a TAME （extended technology acceptance model）, in which the interrelationships among computer self-efficacy, perceived usefulness, intention to use and self-reported use of computer-mediated technology were tested. In addition, the gender- and age-invariant of its causal structure were evaluated. The data were collected from a self-reported questionnaire administered to 477 administrative staff of a public university in Malaysia. The results of structural equation modeling supported the adequacy of TAME. Although the TAME＇s causal structure was applicable to both male and female staff, age group appeared to moderate the structural relationships among the constructs of interest.

4-component 2-D CFDFD method in analysis of lossy circular waveguide with fractal rough surface

In this paper, equivalent surface impedance boundary condition (ESIBC), which takes fractal parameters (D, G) into SIBC, is implemented in the 4-component 2-D compact finite difference frequency domain (2-D CFDFD) method to an- alyze the propagation characteristics of lossy circular waveguide with fractal rough surface based on Weierstrass-Mandelbrot (W-M) function. Fractal parameters’ effects on attenuation constant are presented in the 3 mm lossy circular waveguide, and the attenuation constants of the fi...     

Implementation of advanced peripheral bus interface for MV1O MCU

MV10 is an MCU which consists of PWM,ADC,CAN and some other function blocks.It is designed for car body's control.Advanced peripheral bus (APB) is a low speed AMBA bus connecting low-power peripherals.This paper presents an implementation of APB interface for MV10 MCU.After that,MV10 can be integrated into any AMBA system on chips (SoCs) easily.We have built a multi-core system with ABMA to verify this design.In this system ARM9 is a main processor mounted on AHB and MV10 acts as a low-power and low-speed slaver on APB.Before building this system,some operations are encapsulated into a task with dedicated ID.MV10 works as a co-processor with ARM by acquiring task ID from ARM.The result of simulation indicates that MCU can work well as expected.Based on our design,MV10 can be mounted on any AMBA system from now on.     

CORDIC algorithm based on FPGA

中美数学思维观的比较研究

中美两国数学教育界对学生数学思维的发展都非常重视。我国学者从形象思维、抽象思维、直觉思维等角度对之进行研究和探索;美国学者从儿童生活实际出发,认为学生数学思维包括：匹配与区分、分类、排序、顺序、建模。在论述思维发展时,都结合学生的实际,以案例的方式进行描述。两国在研究的逻辑方法上存在显著差异。我国研究体现出从一般到特殊的特点,而美国的研究则体现出从特殊到一般的特点。比较两国的研究,吸取各自所长,有利于促进我国基础教育数学课程改革的健康发展。
