具有一致等时中心的 Poincar'{e} 系统 $P(2,12)$ 的中心条件，徐金亚，陆征一，本文得到了 Ponicar'e 系统 $P(2,12)$ 中心的充分必要条件。必要性是通过使用 Maple 符号计算得到的前十二阶焦点量证明的。充分性则是验证�

This book describes the key concepts, principles and implementation options for creating high-assurance cloud computing solutions. The guide starts with a broad technical overview and basic introduction to cloud computing, looking at the overall architecture of the cloud, client systems, the modern Internet and cloud computing data centers. It then delves into the core challenges of showing how reliability and fault-tolerance can be abstracted, how the resulting questions ca n be solved, and how the solutions can be leveraged to create a wide range of practical cloud applications. The author's style is practical, and the guide should be readily understandable without any special background. Concrete examples are often drawn from real-world settings to illustrate key insights. Appendices show how the most important reliability models can be formalized, describe the API of the Isis2 platform, and offer more than 80 problems at varying levels

This document specifies the core Abstract Specification and extension mechanisms for Discrete Global Grid Systems (DGGS). A DGGS is a spatial reference system that uses a hierarchical tessellation of cells to partition and address the globe.

Cu-Cr-W和Cu-Cr-Mo三元合金相平衡的实验研究及热力学计算，王翠萍，黄德笑，本文通过EMPA、XRD、DSC等实验方法测定Cu-Cr-W和Cu-Cr-Mo的相平衡。同时基于本次研究得到的实验结果，利用CALPHAD技术对Cu-Cr-W和Cu-Cr-Mo的相图�

5.8 等高图/等高线 等高图（Contour Plot）和等高线（Contour Line）表面上看起来是二 维形式，但实际上展示的是三维数据。我们知道，三维图形往往比二维图 形看起来更具有吸引力，然而在平面上展示三维图形也有其缺陷，最主要 的就是视角问题，一幅三维图形可以有无数种视角，正视、侧视、俯视可 能都会看到不同的信息，而且各种角度下可能都有一部分数据被前面的数 据挡住而不能被看到，当然这些问题都可以通过更灵活的图形设备克服， 如rgl包(Adler and Murdoch, 2010)，但是，在更多的情况下，我们的图形

经典计算机操作系统教材第三版，详细内容可见亚马逊。 https://www.amazon.com/Computer-Systems-Programmers-Perspective-Engineering/dp/0134123832/ref=sr_1_2?ie=UTF8&qid=1541476471&sr=8-2&keywords=computer+systems+a+programmer's+perspective Computer systems: A Programmer’s Perspective explains the underlying elements common among all computer systems and how they affect general application performance. Written from the programmer’s perspective, this book strives to teach readers how understanding basic elements of computer systems and executing real practice can lead them to create better programs. Spanning across computer science themes such as hardware architecture, the operating system, and systems software, the Third Edition serves as a comprehensive introduction to programming. This book strives to create programmers who understand all elements of computer systems and will be able to engage in any application of the field--from fixing faulty software, to writing more capable programs, to avoiding common flaws. It lays the groundwork for readers to delve into more intensive topics such as computer architecture, embedded systems, and cyber security. This book focuses on systems that execute an x86-64 machine code, and recommends that programmers have access to a Linux system for this course. Programmers should have basic familiarity with C or C++. Personalize Learning with MasteringEngineering MasteringEngineering is an online homework, tutorial, and assessment system, designed to improve results through personalized learning. This innovative online program emulates the instructor’s office hour environment, engaging and guiding students through engineering concepts with self-paced individualized coaching With a wide range of activities available, students can actively learn, understand, and retain even the most difficult concepts.
