Book Description
Vibration tests were conducted on both the prototype and a 1:24-scale model of the North Fork Dam, a double curvature arch dam, to determine natural frequencies, mode shapes, damping ratios, and hydrodynamic pressures. Two vibrators mounted on the crest of the dam were used as input excitation sources for both series of tests. Electromagnetic shakers capable of a 40-lb output were used in the model tests, while counterrotating, eccentric mass exciters capable of a 5000-lb output were employed for the prototype. Velocities were measured along the crest and downstream face of the model, whereas accelerations were measured in the same locations on the prototype. Measurements in both curves were taken at the dam-reservoir interface while the structures were excited at resonant frequencies. Damping in both model and prototype ranged from approximately 2 to 5 percent of critical. These values are consistent with structural damping values for these types of structures.

Book Description
This book is about making machine learning models and their decisions interpretable. After exploring the concepts of interpretability, you will learn about simple, interpretable models such as decision trees, decision rules and linear regression. Later chapters focus on general model-agnostic methods for interpreting black box models like feature importance and accumulated local effects and explaining individual predictions with Shapley values and LIME. All interpretation methods are explained in depth and discussed critically. How do they work under the hood? What are their strengths and weaknesses? How can their outputs be interpreted? This book will enable you to select and correctly apply the interpretation method that is most suitable for your machine learning project.

Book Description
Now in its second edition, Prototyping and Modelmaking for Product Design, by practising product development consultant Bjarki Hallgrimsson, is essential reading for both students and design professionals. Prototyping and ModelMaking for Product Design goes behind the scenes to illustrates how prototypes are used to help designers understand problems better, explore more imaginative solutions, investigate human interaction more fully and test functionality so as to de-risk the design process. Following an introduction on the purpose of prototyping, specific materials, tools and techniques are examined in detail, with step-by-step tutorials and industry examples of real and successful products illustrating how prototypes are used to help solve design problems. Workflow is also discussed, using a mixture of hands-on and digital tools. This new edition includes case studies representing technological developments such as prototyping user experience and interactive electronic products, as well as a new expanded section on digital modelmaking tools, including 3D printing and laser cutting. The first chapters of the book explain why prototyping is so important to the design process. The many uses of prototyping will be shown in the context of several comprehensive projects by some of the world's leading design firms. The second part is an introduction to the typical materials used by designers in their prototyping efforts and how to work with them. In all cases, the approach is to use digital and manual tools in a complementary and effective fashion. Tutorials were specifically developed that underline the back and forth of digital and manual ways of working. The emphasis is on the kinds of construction that can be done by the designers themselves. Health and safety is stressed in terms of personal responsibility and awareness. Topics covered include:Definition of prototyping and modelmakingPrototyping as a form of problem solvingModelmakingPhysical and digital prototypesBuidling by hand and using digital technologies
