Grieves教授关于数字孪生发展的又一力作，通篇论文较长，请仔细阅读。 摘要如下:The idea that the information about a physical object can be separated from the object itself and then mirror or twin that object is a concept referred to as the Digital Twin. The Digital Twin is receiving a great deal of interest from manufacturers who make advanced products that have all the characteristics of complex systems. While the Digital Twin concept is becoming better fleshed out and understood, there is much more work to be accomplished. Specifically, the characteristics of the physical product as these become smart, connected product system (SCPS or Physical Twin) need to be defined and described. The success of the Digital Twin model will rest on the value it creates for both the manufac￾turers and the users of their products. There will also be new issues, security among the most important, that need to be surfaced and addressed.

GIS专业教材第二版 Effective use of today’s vast geographic information (GI) resources requires more than just powerful technology for problem solving. It requires science to help us understand the way the world works, and to help us devise effective procedures for making decisions. Three previous editions have established this text as a defining multidisciplinary treatment of the scientific principles that underpin the use of geographic information technologies for problem solving. This extensively revised and updated edition provides a guide to the enduring scientific principles and information systems that support effective use of today’s GI. It also provides a primer on essential methods for analysis of GI, and the ways in which effective management of GI informs policy and action.

Using machine learning to gain deeper insights from data is a key skill required by modern application developers and analysts alike. Python is a wonderful language to develop machine learning applications. As a dynamic language, it allows for fast exploration and experimentation. With its excellent collection of open source machine learning libraries you can focus on the task at hand while being able to quickly try out many ideas. This book shows you exactly how to find patterns in your raw data. You will start by brushing up on your Python machine learning knowledge and introducing libraries. You'll quickly get to grips with serious, real-world projects on datasets, using modeling, creating recommendation systems. Later on, the book covers advanced topics such as topic modeling, basket analysis, and cloud computing. These will extend your abilities and enable you to create large complex systems. With this book, you gain the tools and understanding required to build your own systems, tailored to solve your real-world data analysis problems.
