LINUX下UBI子系统的研究与应用

对Linux中基于MTD(Memory Technology Device)的UBI(Unsorted Block Images)子系统和基于UBI的UBIFS的二者内部工作机制和算法进行分析,在此基础上着重探讨UBIFS实现快速挂载与I/O的原理.在同一嵌入式Linux系统中分别使用直接基于MTD的JFFS2和基于UBI的UBIFS,对它们的挂载和I/O时间进行性能测试比对,证实UBIFS实现嵌入式Linux文件系统的快速挂载与读写.     

基于车辆周期行为的UBI设计

随着定位与导航技术的快速发展,使基于位置信息的各种应用成为可能.在车辆保险领域,让那些驾驶行为习惯良好,以及有着丰富驾驶经验的驾驶员可以最大程度享受到保费上的优惠,有助于减少不安全驾驶行为.通过对车辆周期性行为进行分析,可以评估车辆行驶风险.讨论了周期性行为数据的采集方法,以及用离散傅里叶变换等方法对数据进行分析、归纳.保险公司根据差异化的驾驶行为和特征给出差异化的保费定价,使保费的制定更加合理.     

基于GID的UBI系统研究

针对传统车险中用户关系管理不明显、个性化增值服务少、保费不合理等问题,基于GID技术对UBI系统进行研究。在车联网"端-管-云"架构的基础上,提出了新型的UBI系统模型,从信息感知、初步数据处理、数据传递、云端的驾驶行为数据挖掘和车主的费率等方面对UBI系统进行模块化功能描述和分析。系统的功能分析表明,基于GID的UBI系统在车险行业有很好的应用前景。     

The innovation incubator,university business incubator and technology transfer strategy: The case of Thailand

This study reviews the role of the innovation incubator and university business incubator (UBI) in supporting the entrepreneurial development in Thailand. The university business incubator (UBI) is defined in this paper as an incubator set up by the university to provide office space, equipment, mentoring services as well as other administrative supports to assist the formation of new ventures). In particular, the paper compares the operation of the university business incubators (UBIs) and technology incubators to understand their technology transfer strategies. The analyses, based on the Triple Helix model, also include the government policies to support innovation commercialization in Thailand. The study examines case studies of leading university business incubators (UBIs) (Mahidol University, Chulalongkorn University and King Mongkut's University of Technology Thonburi) and science and technology incubators of the National Science and Technology Agency (NSTDA) and the National Innovation Agency (NIA). The results have shown that the incubation program is one of the major policy mechanisms to support innovation and suggested that UBIs should act as an intermediary between the spheres of university and industry to provide interactive linkages and promote effective utilization of university research. The empirical study provides insightful implications on the move towards the entrepreneurial university and the dynamics of the Triple Helix system in stimulating innovation development and diffusion.     

The complete sequence of a 15 820 bp segment of Saccharomyces cerevisiae chromosome XI contains the UBI2 and MPL1 genes and three new open reading frames

As part of the EEC yeast genome program, a fragment of 15 820 bp from the right arm of Saccharomyces cerevisiae chromosome XI has been sequenced. This fragment corresponds roughly to the centromere-distal half of cosmid pUKG046 and to a small fragment of cosmid pUKG096, which are located approximately 150 kb from the centromere. It contains four open reading frames (ORFs) which encode potential proteins of more than 100 amino acid residues, as well as the UBI2 gene which carries an intron and does not show up as an ORF in the sequence analysis programs. One of the putative proteins, YKR412, is very rich in serine and has significant homology at the carboxyl end to Nopp140 phosphoprotein. YKR413 has several predicted transmembrane domains. YKR15, which has been recently cloned as the MPL1 gene, encodes a polypeptide that shows homologies to myosin heavy chain and to the cytoskeleton protein Uso1.     

UBIFS闪存文件系统分析与研究

该文详细介绍了无序区块映像文件系统（Ubifs）三个组成模块,并对其中使用的垃圾回收和损耗均衡算法做了深入分析。同时介绍了一个新特性：快速映射。随后对快速映射进行实验分析,证明快速映射的确可以大幅降低挂载时间。     

一种逻辑块温度和物理块年龄的磨损均衡算法

UBIFS文件系统中由UBI子系统实现磨损均衡管理,但研究发现UBI现有的磨损均衡策略存在着很大的局限性.提出了一种基于逻辑块温度和物理块年龄的新的磨损均衡算法,称为LTPA(leb temperature peb age)算法.该算法实现高温逻辑块与青年物理块,低温逻辑块与老年物理块之间的映射.通过局部操作时间的方法...
