The book reveals the latest research findings and innovations in electromagnetic wave absorption and shielding by exploring the design and application of absorbent materials, the optimization of shielding structures and the improvement of testing and evaluation methods.From conductive materials to magnetic materials and from composite materials to nanomaterials, the book details the characteristics and advantages of various absorbent materials and explains their applications in electromagnetic wave absorption and shielding. It then introduces the different methods of electromagnetic shielding, including structural shielding and material shielding. It also studies experimental and testing techniques, including measurement methods and evaluation criteria for electromagnetic wave absorption performance.The book will be of interest to researchers and graduate students in electromagnetic compatibility, materials science and engineering.

This two-volume set of LNAI 13551 and 13552 constitutes the refereed proceedings of the 11th CCF Conference on Natural Language Processing and Chinese Computing, NLPCC 2022, held in Guilin, China, in September 2022.The 62 full papers, 21 poster papers, and 27 workshop papers presented were carefully reviewed and selected from 327 submissions. They are organized in the following areas: Fundamentals of NLP; Machine Translation and Multilinguality; Machine Learning for NLP; Information Extraction and Knowledge Graph; Summarization and Generation; Question Answering; Dialogue Systems; Social Media and Sentiment Analysis; NLP Applications and Text Mining; and Multimodality and Explainability.

The science and technology related to semiconductors have received significant attention for applications in various fields including microelectronics, nanophotonics, and biotechnologies. Understanding of semiconductors has advanced to such a level that we are now able to design novel system complexes before we go for the proof-of-principle experimental demonstration.This book explains the experimental setups for optical spectral analysis of semiconductors and describes the experimental methods and the basic quantum mechanical principles underlying the fast-developing nanotechnology for semiconductors. Further, it uses numerous case studies with detailed theoretical discussions and calculations to demonstrate the data analysis. Covering structures ranging from bulk to the nanoscale, it examines applications in the semiconductor industry and biomedicine. Starting from the most basic physics of geometric optics, wave optics, quantum mechanics, solid-state physics, it provides a self-contained resource on the subject for university undergraduates. The book can be further used as a toolbox for researching and developing semiconductor nanotechnology based on spectroscopy.

Discover the difference between making a robot move and making a robot think. Using Mindstorms EV3 and LeJOS-an open source project for Java Mindstorms projects-you'll learn how to create Artificial Intelligence (AI) for your bot. Your robot will learn how to problem solve, how to plan, and how to communicate. Along the way, you'll learn about classical AI algorithms for teaching hardware how to think; algorithms that you can then apply to your own robotic inspirations.If you've ever wanted to learn about robotic intelligence in a practical, playful way, Beginning Robotics Programming in Java with LEGO Mindstorms is for you.What you'll learn:Build your first LEGO EV3 robot step-by-stepInstall LeJOS and its firmware on Lego EV3Create and upload your first Java program into Lego EV3Work with Java programming for motorsUnderstand robotics behavior programming with sensorsReview common AI algorithms, such as DFS, BFS, and Dijkstra's AlgorithmWho this book is for:Students, teachers, and makers with basic Java programming experience who want to learn how to apply Artificial Intelligence to a practical robotic system.
