Plasma-assisted molecular beam epitaxy （MBE） was used to grow ZnO （0001） layers on GaN（0001）/4H-SiC buffer layers deposited in the same growth chamber equipped with both N- and O-plasma sources. The GaN buffer layers were grown immediately before initiating the growth of ZnO. Using a substrate temperature of 440℃- 445℃ and an 02 flow rate of 2.0-2.5 sccm, we obtained ZnO layers with smooth surfaces having a root-mean-square roughness of 0.3 nm and a peak-to-valley distance of 3 nm shown by AFM. The FWHM for X-ray rocking curves recorded across the ZnO（0002） and ZnO（1015） reflections were 200 and 950 arcsec, respectively. These values showed that the mosaicity （tilt and twist） of the ZnO film was comparable to corresponding values of the underlying GaN buffer. It was found that a substrate temperature 〉 450℃ and a high Zn-flux always resulted in a rough ZnO surface morphology. Reciprocal space maps showed that the in-plane relaxation of the GaN and ZnO layers was 82.3% and 73.0%, respectively and the relaxation occurred abruptly during the growth. Room-temperature Hall-effect measurements showed that the layers were intrinsically n-type with an electron concentration of 10^19 cm-3 and a Hall mobility of 50 cm2.V-1 .s-1.

目前,移动计算正变得日益流行。由于相关技术的进步,如无线设备、移动计算机和其他一些应用的发展,人们能够随心所欲地在任何时间和地点访问互联网。但是,对于移动计算在紧急灾害报警处理方面的应用所作的研究并不多。该技术的关键在于使得任何位置的用户能够实时获得并访问信息,在灾害发生前通知人们采取必要的防护措施,这对于营救工作是很有帮助的,因为如果营救人员知道灾害发生的精确位置和周围环境,他们的营救工作就会更加顺利,效率也会提高。本文探讨了移动GIS计算在获得上述目标方面的应用,概括了一种解决途径和多种结构模式。其中包含无线网络设备,网络GIS的应用,Java移动模拟器在便携式电脑中的远程访问应用。论文详细阐述了怎样利用这些技术设备在短时间内传输数据,并且基于瘦客户方法设计了一个应用系统,其中考虑了对连接不同用户的数据库的单独访问。系统设计了针对不同用户的客户型用户界面,包括不使用小设备和使用如移动电话等小设备来显示和更新数据的用户,并且基于Java掌上模拟器来对移动电话进行研究。本系统使用来自津巴布维气象中心的天气数据进行测试实验,将数据的分析结果存储于一个数据库中,与不同的城市进行连接。在试验过程中,利用本系统对用户发出灾害,如火灾、飓风或地震等的警告。一旦灾害发生,用户就能通过电话或网页在短时间内收到信息,该信息会被突出显示,营救人员能据此展开营救,此外,还可以图像的形式对灾害损失范围进行显示,向全世界发出救援信息。通过对本系统的试验过程进行分析,发现数据的传输也取决于网络服务和代表设备如宽带的技术进步。另一点需要注意的是小设备的内存限制,这样用户每次只能看到有限的数据显示,这一问题有待新技术的发展加以解决。

图像采集平台的设计与图像融合的实现

图像采集平台的设计与图像融合的实现

作者： Armah adolph Nii Armah（岳飞）华南理工大学

学位级别：硕士

In recent years machine vision has been a hot cake and fast catching the growing market of the global word. The impact of image processing can’t be rude out in this our world because it has become part of us in everything we do. It is required to obtain high resolution or to say a clear images in many fields such as, in the field of astrology, criminal investigation, traffic monitoring, video surveillance, sporting events gesture recognition and medicine etc. In the study of Multi-lens Multi-sensor（MLMS）, image merging is an important and hot commodity if I can put it in that way or in the context of big issues. The Aim of this research is to design a platform on which two cameras will be mounted at distance apart from each other and at different angel parallel to acquire an image under high switching Light source. Detail explained of the hardware and software of the camera platform and light. Work on a half-image with low resolution and fuse it with another half-image taken with the same condition at the same time with two camera sensors. This thesis proposes to construct an image synthesis system based on IMAGE PLATFORM DESIGN AND REALIZATION OF IMAGE FUSION. The cost of these system is of low-cost compare to others but fit to do work excellently. The structure of this platform is simple and intends to use two cameras which are placed parallel to each other on the same bar with same focal length to build the image acquisition device. This paper is mainly about 3 problems:1. Design and mechanical structure of the system of the camera platform.2. Comparing many ways of capturing the images in a parallel at different distance and angels and at the end choosing the best one and the analysis of the *** result shows that, the images we captured meet our requirements. And they are good preparations for the next work of image processing.3. Image Reconstruction Realization

随着全球性金融危机的爆发,又一轮企业合并大潮初露端倪。但令人担忧的是,综合各种研究统计结果发现,企业合并项目的失败率超过一半,在个别国家和地区,这个比例甚至高达惊人的90%。人员配置和业务衔接固然重要,但对IT部分敷衍了事早已行不通,何况是信息化建设的重要性和迫切性已经受到广泛认同的今天。那么,如何应对企业合并中的IT整合问题,本文能够给企业管理者一些建议和启迪。

青光眼的表现,错综复杂。其中一组具有某些共同特点,当我们遇见一例之后,即可诊断其他同型病例。这组病例是一个综合病征,即复发性急性非充血性青光眼,经常合并轻度睫状体炎。1948年我们曾报告9例,命名为「青光眼——睫状体炎综合病征」(syndrome of glaucomatocycliticcrises),以后由于个人不断观察及其他眼科医师的报告,我们的经验逐渐丰富。这些强而有力的实事的支持,使我们深信,这些病例确系一种特型青光眼,牠的预后良好,治疗方法也和一般青光眼不同。Kronfeld 氏曾描述此型病例的特点,认为是「急性眼压增高,同时合并轻度睫状体炎」。虽然他没有详细讨论,我们相信他所指的就是这类病例。
