Science Letters: Efficient page layout analysis on small devices

Previously we have designed and implemented new image browsing facilities to support effective offline image contents on mobile devices with limited capabilities: low bandwidth, small display, and slow processing. In this letter, we fulfill the automatic production of cartoon contents fitting small-screen display, and introduce a clustering method useful for various types of cartoon images as a prerequisite stage for preserving semantic meaning. The usage of neural networks is to properly cut the various forms of pages. Texture information that is useful for grayscale image segmentation gives us a good clue for page layout analysis using the multilayer perceptron (MLP) based x-y recursive algorithm. We also automatically frame the segment MLP using agglomerative segmentation. Our experimental results show that the combined approaches yield good results of segmentation for several cartoons.     

A modified incremental shuttle run test for the determination of peak shuttle running speed and the prediction of maximal oxygen uptake

The aim of this study was to determine the incidence of subject drop-out on a multi-stage shuttle run test and a modified incremental shuttle run test in which speed was increased by 0.014m.s-1 every 20-m shuttle to avoid the need for verbal speed cues. Analysis of the multi-stage shuttle run test with 208 elite female netball players and 381 elite male lacrosse players found that 13 (+/-3) players stopped after the first shuttle of each new level, in comparison with 5 (+/-2) players on any other shuttle. No obvious drop-out pattern was observed on the incremental shuttle run test with 273 male and 79 female undergraduate students. The mean difference between a test-retest condition (n= 20) for peak shuttle running speed (-0.03+/- 0.01m.s-1) and maximal heart rate (0.4+/- 0.1 beats.min-1) on the incremental test showed no bias (P > 0.05). The 95% absolute confidence limits of agreement were 0.11m.s-1 for peak shuttle running speed and +/-5 beats.min-1 for maximal heart rate. The relationship (n= 27) between peak shuttle running speed on the incremental shuttle run test (4.22+/- 0.14m.s-1) and VO2max (59.0+/- 1.7ml.kg-1.min-1) was r=0.91 (P< 0.01), with a standard error of prediction of 2.6ml.kg-1.min-1. These results suggest verbal cues during the multi-stage shuttle run test may influence subject drop-out. The incremental shuttle run test shows no obvious drop-out patten and provides a valid estimate of VO2max.     

城与乡的关系史:新型城镇化思考

从古代的城乡一体,到近代的城乡分离,直至当代的城乡割裂,中国城市的起源和进化以及城乡关系发展史,是中国未来城镇化发展的背景和前车之鉴。中国城市化的本质是关于一个植根于超过五千年农业文明的乡村社会,在经过20世纪50~70年代的高度集体化后,如何在政府主导的市场改革下迈向城市化的进程。中国未来城镇化需要跳出以工业化推动城市化的传统西方思维,从历史的视角重新审视中国城市及传统乡村社会的内涵,探索如何在新一轮城镇化进程中构建互动共融的城乡关系。     

Sustainability and Education: To Sink—or to Swim?

In the 1960s, the role of engineering education was clear, whereas in the 1990s there is a search for a new rationale. These changes have been wrought by social concerns for the environment at both local and global levels. This trend will accelerate further, and both the rate of development of the trend and its implications have been underestimated. There is now a hope and expectation that technology, until now a contributor to environmental problems, can in the future play a large part in the reduction of these problems. While professional engineering organizations have addressed the problem at a policy level, implementation is a major difficulty. This is also true in education, despite efforts by some schools of engineering to adapt existing courses in an environmental direction. It is now clear that the changes needed are too fundamental and the rate of change too great to be dealt with adequately by adaptation. Basic questions of philosophy and capacity will have to be addressed by academia, engineering practice and major business.
