Donald Norman's best-selling plea for user-friendly design, with more than 175,000 copies sold to date, is now a Basic paperback. First, businesses discovered quality as a key competitive edge; next came service. Now, Donald A. Norman, former Director of the Institute for Cognitive Science at the University of California, reveals how smart design is the new competitive frontier. The Design of Everyday Things is a powerful primer on how--and why--some products satisfy customers while others only frustrate them.

物联网（IoT）是信息和通信技术行业（ICT）中的下一个重要事物。 物联网能够将小规模的系统连接到大规模的系统。 这些数十亿台设备一起构成了庞大的设备网络，我们将其称为物联网。 随着技术的最新发展，观察到物联网设备数量的巨大增长，这也增加了对能源的需求。 这就产生了低功耗物联网的需求。 绿色物联网。 本文概述了物联网，物联网的元素和物联网的应用。 此外，还讨论了绿色物联网，绿色物联网技术和绿色物联网应用。 最后，讨论了挑战。

Explore the current state of the production, processing, and manufacturing industries and discover what it will take to achieve re-industrialization of the former industrial powerhouses that can counterbalance the benefits of cheap labor providers dominating the industrial sector. This book explores the potential for the Internet of Things (IoT), Big Data, Cyber-Physical Systems (CPS), and Smart Factory technologies to replace the still largely mechanical, people-based systems of offshore locations. Industry 4.0: The Industrial Internet of Things covers Industry 4.0, a term that encapsulates trends and technologies that could rewrite the rules of manufacturing and production. What You'll Learn: What are the Industrial Internet and Industrial Internet of Things Which technologies must advance to enable Industry 4.0 What is happening today to make that happen What are examples of the implementation of Industry 4.0 How to apply some of these case studies What is the potential to take back the lead in manufacturing, and the potential fallout that could result Who This Book is For: Business futurists, business strategists, CEOs and CTOs, and anyone with an interest and an IT or business background; or anyone who may have a keen interest in how the future of IT, industry and production will develop over the next two decades.

ppt 第一页 it is my pleasure to take a presentation .my topic is the internet of things. ppt 第二页 firstly ,I should denote that the internet of things is a part of smart earth which is ibm ‘s dream .Except for internet of things ,the smart earth is composed of two other parts, they are the internet and internet clouds ppt第三页 Now I will introduce the internet of things. ppt第四页 The internet of things can be divided into three layers: sensor layer, network layer and the application layer. the bottom level is sensor layer . the function of sensor layer is to distinguish the objects, and collect information。 this layer includes two dimensional barcode label and conversational machine, RFID tags and literacy device, cameras, GPS, sensors, terminal, sensor network ,and so on。this layer is mainly used to identify the object, gathering information, just like human‘s nose eyes and ear . the second level is network layer . network layer is used for Information transmission and processing .the network layer includes network management center, information center and intelligent processing center, and so on. The network layer will transfer and process information obtained by sensor layer. it is similar to human‘s nerve center. the top level is application layer . the application layer is related to the industry demand .and different needs require different applications

The book is ideal for Python developers who want to explore the tools in the Python ecosystem in order to build their own IoT applications and work on IoT-related projects. It is also a very useful resource for developers with experience in other programming languages that want to easily prototype IoT applications with the Intel Galileo Gen 2 board.
