This article provides an overview of recent developments in mainmemory database systems. With growing memory sizes and memory prices dropping by a factor of 10 every 5 years, data having a “primary home” in memory is now a reality. Main-memory databases eschew many of the traditional architectural pillars of relational database systems that optimized for disk-resident data. The result of these memory-optimized designs are systems that feature several innovative approaches to fundamental issues (e.g., concurrency control, query processing) that achieve orders of magnitude performance improvements over traditional designs. Our survey covers five main issues and architectural choices that need to be made when building a high performance main-memory optimized database: data organization and storage, indexing, concurrency control, durability and recovery techniques, and query processing and compilation. We focus our survey on four commercial and research systems: H-Store/VoltDB, Hekaton, HyPer, and SAP HANA. These systems are diverse in their design choices and form a representative sample of the state of the art in main-memory database systems. We also cover other commercial and academic systems, along with current and future research trends.

基于仿射和 B 样条网格的两个 2D 彩色/灰度图像或 3D 体积或点数据的配准和数据拟合。 配准可以基于强度/像素,或基于地标/对应点(参见 OpenSurf),或组合进行。 描述 基于像素的配准: 该函数是 D. Rueckert 等人中 b 样条配准算法的(增强)实现。 “使用自由形式变形的非刚性配准:对乳房 MR 图像的应用”。 包括 Rueckert(薄金属片弯曲能量)和 Jacobian(微分形)函数的平滑度惩罚。 还包括将局部标准化互信息作为配准误差,允许图像或体积为不同类型/模态,例如 MRI T1 和 T2 患者扫描。 这个怎么运作: 构建了一个 b 样条控制点网格,它控制输入图像的变换。 误差测量用于测量运动图像和静态图像之间的配准误差。 准牛顿 Matlab 优化器 fminlbfgs(也在 Mathworks 上)用于移动控制点,以实现两幅图像之间的最佳配准,
