基于M型超声信号的心动周期自动检测

M型超声波主要用于临床上心脏疾病的诊断,依据心肌的声学以及弹性特征,是一种无创性的诊断技术。本文提出了一种新的方法来自动判定心动周期。利用超声脉冲多普勒信号,对不同时刻的心脏振动进行相关性分析,找到两组一一对应的连续时点数列,从而判断出心脏运动的周期。本文最后进行了临床超声波数据的实验,并和医生的手动方法相比较。结果表明本文提出的检测方法达到了临床检测的效果,在心脏疾病的超声波诊断研究方面具有重要意义。     

Determinants of China's Technology Availability and Utilization 2006–2009: A Spatial Analysis

There are significant regional disparities in the level of technology availability and utilization in China. This study analyzes determinants of technology availability and utilization in China's 31 administrative units using data on technology adoption and socioeconomic factors. It examines the extent of spatial autocorrelation on technology levels and regression residuals, and provides exploratory spatial cluster analysis of technology attributes interpreted by four regional policy approaches. An exploratory conceptual model is established, based on diffusion of innovations theory and prior digital divide research. Regression findings indicate the most significant determinant of technology availability and utilization is export commodities value. This is followed by published books, tertiary employment, non-state-owned employment, and innovation funds of enterprises. The conceptual model is discussed in light of these findings and suggestions are offered for China's technology policy.     

The representation of ‘Asia’, ‘occupational forces’ and ‘women’ against the backdrop of post‐war Japanese culture: from the system of censorship to the present

This paper is one of the attempts to show how each East‐Asian regional country’s memory of the war has been related to the post‐war literatures and movies restricted by the structure of the Cold War. In particular, this paper takes up the issue of how the structure of Japanese culture after World War II was heavily influenced by the Cold War. When Japan was under the Occupational Forces, Japanese writers and film directors settling on the subject matter of the war were not free from the strain of the systematic censorship by GHQ. Translating into mechanisms of their works using the body or woman (comfort woman) by squarely facing the facts of the East‐Asian history, this paper reconsiders the body of post‐colonial Japan.
