Partial K-space Sampling MRI based on Compressed Sensing

磁共振成像(MRI)由于具有无辐射、多平面成像、扫描参数多、提供病理生理信息多、软组织对比分辨率高等优点，己成为临床医学和科研医学的一种十分重要的检测手段。现有MRI技术的不足之处在于成像速度慢，并且在检查过程中，病人自主或不自主的活动可引起运动伪影，影响诊断。如何在不改变现有硬件设备的基础上，获得更快的成像速度是MRI急需解决的一个重要问题，也是一个研究热点问题。 压缩传感（CS）理论是新近提出的一种新的非线性信号采样理论，该理论有效突破奈奎斯特采样定理的束缚，可由远低于奈奎斯特采样定理要求的数据量重建信号。本文在充分研究了CS理论之后，将CS理论应用于MRI，利用部分K空间数据重建MR图...Magnetic resonance imaging (MRI) has become a very important medical test because of its non-radiation, Multiplan imaging, scanning many parameters to provide path physiological information and more advantages of soft-tissue contrast resolution, clinical and scientific research.

贫困问题是著名的“三P”（pollution，population，poverty）问题之一。虽然技术逐渐进步和物质逐渐丰富，人类生活质量逐渐提高，但是贫困始终存在于各个国家和地区。本文研究的是基于CHNS的微观数据，考察金融发展如何影响家庭贫困率和贫困深度。利用12个省市的存贷款/GDP和存贷款比和失业率等数据，采用randomeffect模型，以家庭人均收入是否处于贫困线以下作为被解释变量，家庭人均收入处于贫困线以下设为1，家庭人均收入处于贫困线以上设为0，将家庭特征、户主特征和金融发展指标作为解释变量，如家庭规模、学生人口占家庭人口比、60岁以上老年人占家庭人口比及6岁以下儿童占家庭人口...In this paper, we study the relationship between financial development and poverty, using China health and nutrition survey (CHNS) data and twelve provinces’ data of the deposit/GDP、loan/GDP、deposit/lending, unemployment ratio from 1991-2011, by using the probit random effect model,use the family poverty as a binary dependent variable, the family characteristics such as the numbers of families, st...学位：经济学硕士院系专业：经济学院_西方经济学学号：1722013115199

Financial Development and Financial Security of East Asian Developing Economies：Cases Study of Five Crisis-Stricken Countries

1997年亚洲金融危机后，东亚发展中经济体开始了新一轮金融改革，进一步开放各国的金融市场，金融全球化步伐加快。经过一系列金融改革，东亚发展中经济体的金融体系进一步完善，传统金融银行业的控股格局有所改变，金融稳定性有所增强。但在金融全球化浪潮下，东亚发展中经济体的金融体系更容易受到全球金融市场及其他金融市场稳定性的影响，金融稳定与持续发展受到更加严峻的考验。然而，国际游资等外在因素的冲击并不是关键所在，一国本身是否拥有一个健康的金融体系，才是决定能否避免重大金融危机或市场波动的关键。本文主要以东亚五个危机重灾国（泰国、印尼、韩国、马来西亚和菲律宾）为例，探讨金融全球化的背景下东亚发展中经济体的金...After the Asian financial crisis in 1997, developing economies in East Asia initiated a new round of financial reforms by further opening their financial markets, which have become more integrated with the global financial market.

Data will be collected with four age cohorts in three to four waves, with each individual student as a data unit, from several sources, including parent survey, teacher survey, school program survey, assessment data and/or student survey. Local educational authorities in 25 cities or counties will also be surveyed in three waves. This proposed project will span second three years for data collection on students with disabilities receiving special education at preschool, elementary, junior and senior high school levels in the school years of 2010, 2011 and 2012. Data on Grades 1, 3, 6, 7, 9, 10, 12, as well as post-secondary year 1, will all be collected. Follow-up surveys to local educational authorities in divisions of special education will also be employed and as a result, a national picture of special education practices and changes will be analyzed to address issues of academic and practical importance. Student samples will be randomly selected from Special Education Transmit Net according to disability categories. Questionnaires which cover the most influential issues in students, families, and school education will be separately designed and completed by parents, teachers, school administrators, and disabled students placed in regular classes. Most importantly, after collection data and cleaning, this database will be open to the researchers in the fields of special education and allied professionals as well so that in-depth analyses can be performed for differing purposes of advanced studies.
