单校验码为子码的多维Turbo乘积码性能分析

Turbo乘积码是一类易于硬件实现高速迭代译码的分组码,本文对单校验码为子码的高维Turbo乘积码的软输入软输出迭代译码算法进行了详细的分析。进而将其与QAM调制结合起来,提出了一种简化的、便于硬件实现的联合解调译码方案,充分利用了高维Turbo乘积码优越的纠错性能。仿真结果表明这种简化方案在高斯和衰落信道下的译码性能很好。     

基于视频压缩编码的动态图像水印方案

提出了一种新的基于视频压缩编码的动态图像水印方案。在嵌入水印时,充分考虑动态图像压缩编码的特性,对帧内编码帧(I帧),将水印信息嵌入到DCT低频系数中;而对帧间编码帧(P,B帧),结合动态补偿/离散余弦变换(MC/DCT)混介编码,把水印信息嵌入到运动补偿后的残差图像的自流成分中。同时,在水印嵌入时,采用扩频技术与多维水印相结合的方法,并通过相关检测的方法判断水印的存在。由于水印的检测是对视频码流直接实施的,不需要对压缩数据进行完全解码,从而大大降低了计算量,提高了视频数据水印的适用性。     

NiSi／Si（001）声子模式对称性分析

通过极化拉曼对以Si（001）为衬底、生长方向为NiSi[200]//Si[001]NiSi薄膜材料的拉曼峰进行了声子模式的分组,确定实验得到的NiSi薄膜的六个拉曼峰分别属于三类声子模式．其中213cm^-1、295cm^-1和367cm^-1处拉曼峰属于Ag对称性;196cm^-1和254cm^-1处拉曼峰属于B3g对称性;401cm^-1。处拉曼峰属于B1g或B2g对称性．     

四川地震旅游＂R—P＂转化适宜性评价研究——基于ETOS和R—P关系模式的分析

地震旅游是人们出于对地震相关事象的认知与体验而进行的地震文化体验活动。地震旅游资源是地震旅游的物质基础和精神依托,其所含内容十分丰富。汶川地震在给灾区人民带来灾祸的同时,也遗留下了众多价值较高的伴生物、遗留物和附生物。合理有效地对这些资源进行旅游开发,不仅有助于地震灾区的恢复与重建,而且还可以弘扬爱国主义精神、凭吊灾害事件、加强防震抗灾和地震科普知识教育。文章利用地震旅游机会谱（ETOS）和“资源-产品”（R—P）关系模式对四川地震旅游资源的“R—P”转化适宜性进行了评价,并据此提出了四川地震旅游开发与管理的基本思路。     

二维非平稳信号的小波谱均衡处理方法

小波变换对信号的分时分频的精细表达和多分辨率的全面把握,使我们能更深入地认识信号和噪声的特性,便于基于小波域进行更有效的高分辩率的处理工作;而谱均衡处理技术是提高信号纵向分辨率的有效方法,所以本文提出了将两种方法结合起来共同进行提高二维非平稳信号分辨率.其基本思想是先将二维非平稳信号进行小波分频处理,得到不同尺度的信号;然后将各尺度上的信号分别进行谱均衡处理,再将经谱均衡处理的不同尺度信号进行重建,从而得到高分辨率信号,我们将上述方法称之为小波谱均衡处理.利用提出的新方法进行实际信号处理,处理结果表明该方法的处理效果要好于常规的谱均衡方法,它既能提高二维非平稳信号的纵向分辨率,同时又能保持原信号的固有特征.     

The impact of inclusive education reforms on students with disability: an international comparison

ABSTRACT

When the Salamanca Statement called upon States to recognise the ‘necessity and urgency’ of providing students with a disability access to the regular education system (UNESCO 1994, viii), both Australia and the United States of America had existing legislative and policy documents articulating the rights of students with a disability to access regular education. Since that time both countries have clarified and amended their respective laws and policies, and signed the Convention on the Rights of Persons with Disabilities (UN 2006) which urges States to reallocate resourcing to inclusive education, and to reduce segregation. In this article, I examine the policy reforms in each country and analyse aggregated and disaggregated student placement data within each context to consider the impact of these reforms for different groups of students. Results show that the different reform journeys in each context produced different outcomes for students in each country, with segregation increasing in Australia and decreasing in the USA. The results also suggest that the impact of these policies has not been proportionate across categories as students on the Autism Spectrum are more likely to experience educational segregation or exclusion in both countries.

Mothers’ Depressive State ‘Distorts’ the Ratings of Depression they give for their Sons with an Autism Spectrum Disorder

Depression is highly prevalent in children who have an Autism Spectrum Disorder (ASD), potentially confounding accurate diagnosis and treatment planning. Although information about the depressive status of a child is often collected from parents, there is evidence of distortion in parental assessments of their offspring’s depression. This distortion was investigated in a sample of 132 mothers of boys with an ASD. Results indicated that, as predicted from previous studies, there was a significant correlation between the depressive state of the mothers and the ratings they gave for their sons’ depression. However, in contradiction to the expected influence direction, mothers who were minimally depressed under-estimated their sons’ depression when cross-validated by structured clinical interviews for depression conducted by a third party, rather than mothers who were more severely depressed exaggerating their sons’ depression. Implications for clinical assessment of the presence of depression in boys with an ASD are discussed.     

大学生头发中微量元素的检测及其与膳食结构的关系

本文从群体角度出发,调查测定大学生的发样中锌、铜、铁、钙、镁、铝等微量元素的含量与膳食结构的关系,我们随机抽取了大学生168名进行头发中微量元素的测定。结果表明,大学生缺锌、钙、铁,这与饮食有关。所以我们应重视缺锌、缺铁和缺钙的防治,并应选择完善“科学配餐”。
