Much has been written concerning the manner in which healthcare is changing, with a particular emphasis on how very large quantities of data are now being routinely collected during the routine care of patients. The use of machine learning meth- ods to turn these ever-growing quantities of data into interventions that can improve patient outcomes seems as if it should be an obvious path to take. However, the field of machine learning in healthcare is still in its infancy. This book, kindly supported by the Institution of Engineering andTechnology, aims to provide a “snap- shot” of the state of current research at the interface between machine learning and healthcare.

This edition of Digital Image Processing is a major revision of the book. As in the 1977 and 1987 editions by Gonzalez and Wintz, and the 1992, 2002, and 2008 editions by Gonzalez and Woods, this sixth-generation edition was prepared with students and instructors in mind. The principal objectives of the book continue to be to provide an introduction to basic concepts and methodologies applicable to digital image processing, and to develop a foundation that can be used as the basis for further study and research in this field. To achieve these objectives, we focused again on material that we believe is fundamental and whose scope of application is not limited to the solution of specialized problems. The mathematical complexity of the book remains at a level well within the grasp of college seniors and first-year graduate students who have introductory preparation in mathematical analysis, vectors, matrices, probability, statistics, linear systems, and computer programming. The book website provides tutorials to support readers needing a review of this background material

Research on microwave power amplififiers has gained a growing importance demanded by the many continuously developing applications which require such subsystem performance. A broad set of commercial and strategic systems in fact have their overall performance boosted by the power amplififier, the latter becoming an enabling component wherever its effificiency and output power actually allows functionalities and operating modes previously not possible. This is the case for the many wireless systems and battery-operated systems that form the substrate of everyday life, but also of high-performance satellite and dual-use systems.

摘要：无线传感器网络（Wireless Sensor Networks，wSN是由许多具有低功率无线收发装置的传感器节点组成，它们监测采集周边环境信息并传送到基站进行处理在某一时刻通过wSN采集的数据量非常大，如何正确、高效地处理这些数据成为当前WSN研究中的一个热点。传感器节点一般部署在恶劣环境中，一些偶然因素会使采集的数据中出现不准确的数据，用户依据这样的数据很难准确判断出被测对象的真实状态。基于模糊理论的决策级数据融合算法能够很好的解决这个问题本文以国家863研究项目《基于无线传感器网络的铁路危险货物在途安全状态监测技术研究》为背景，结合铁路运输中棉花在途状态监测系统的开发，在分析了当前有效的决策级数据融合技术基础上，提出了基于模糊理论的决策级数据融合算法，该算法通过对采集数据进行处理和分析，以获得准确的被测对象状态的描述。本文的主要工作包括：（1）分析了WSN中传统的决策级数据融合算法，如自适应加权数据融合算法和算术平均数数据融合算法，总结这两种算法的优缺点和检测系统的需求，进步明确理想算法应达到的目标。（2）提出了基于模糊理论的两阶段数据融合算法：该算法第一阶段利用基于贴近度的数据融合算法进行同类数据的融合校准，这一阶段的目的是剔除错误的和可信度较差的数据，得到相对更加准确的数据，第二阶段利用模糊推理对第个阶段得到的异类数据进行融合推理，得到被测对象当前状态的描述，为决策提供支持（3）结合实测数据仿真本文所提出的算法，结果证明与传统的融合算法相比，可以更加准确的描述被测对象状态
