基于小波变换的低比特率图像编码研究

运用小波变换理论,结合人类视觉系统特性,提出一种基于SPIHT算法的低比特率图像压缩的改进算法.实验证明,该算法在平滑图像的压缩中有较好效果,在低比特率压缩下减少了Gibbs现象,边缘模糊现象得到改善.     

泰宁1：1万DEM的生成及应用

以福建省泰宁县为例，详细给出了在Surfer 8.0中利用地形图生成DEM数据的具体流程和实际步骤，并进一步在Erdas Image 8.7中生成了坡度坡向图和三维模拟飞行，经实践证明该方法确实能快速有效的生成大批量的DEM基础数据，且经济实用，为其它地区批量生成DEM和DEM的应用提供了借鉴。     

试论现代陶艺的设计意念

陶艺在制作前必须有一个想象，这时陶艺设计的意念就产生了。在意念的指导下，赋予材料以特定的存在形式，使其成为具有一定审美价值的陶瓷艺术作品。在现代设计潮流的影响下，现代陶艺设计呈现出夸张、寓意、怪异的视觉特征，给人以视觉冲击，现代陶艺所表现的倾向是艺术家“自我”的内心世界，是“心理”的写实。     

Jack in two boxes: A postmodern perspective on the transformation of persons into portraits

The paper explores issues surrounding portrayal in educational research and interrogates the notion of a life as a textual product, via an analysis of two short biographical narratives which happen to portray the same person — a British primary school head teacher nearing the end of his career. The discrepancies between these two texts point to the problematic nature of the relationship between person and portrait, and make visible some of the textual devices that writers/researchers use in order to achieve coherence and authenticity in biographical narratives.     

School meal time and social learning in England

ABSTRACT

This paper presents an ethnographic account of the culture of school meal time at Peartree Academy, with a specific focus on notions of social learning. This qualitative study is focused on a collection of interviews, observations, field notes and analyses what happens when the school organises its canteen as a restaurant. The focus moves away from the traditional realms of nutrition and explicitly introduces the notion of social learning in its informal sense through which a conceptual framework of a skills model is applied. The paper argues how the school dining hall known as the restaurant can foster opportunities for a form of social competence which is not necessarily seen but can be experienced in the social reproduction of its actors. The findings highlight tensions of control within the environment, which are said to impinge upon these social learning opportunities from occurring.     

教育首先要讲科学

本文针对中小学教育的现状,通过生理、心理的科学分析,阐明教育首先要讲科学,不仅要遵循学生身体的发展规律,更要遵循学生心理的发展规律,那些违背规律的做法是极其有害的,是需要引起重视并加以纠正的。

浅析机械基础教学中抽象与具体的转化

抽象和具体是对立的,教学中将概念与实际结合起来,使抽象变具体,通过实例理解概念,可收到良好的教学效果。     

基于SuperMap的地形图图幅查询系统设计与实现

基于VB和SuperMap Objects 2008平台,设计实现地形图图幅查询系统.该系统可在1954年北京坐标系或1980年西安坐标系下,实现任意单点或批量坐标解算任意国家基本比例尺地形图新、旧图幅编号,并能根据任意新、旧图幅编号计算四角图廓坐标,并可视化输出.
