"The methods change, but the message stays the same." This saying is the guiding light for faithful Christians in a changing world. But author Shane Hipps reveals the error in this thinking. Instead he demonstrates how changing the methods always changes the message. He shows us the hidden power of technology to shape our faith in unexpected ways.

Presents a comprehensive introduction to the selection, operation, and testing of infrared devices, including a description of modern detector assemblies and their operation This book discusses how to use and test infrared and visible detectors. The book provides a convenient reference for those entering the field of IR detector design, test or use, those who work in the peripheral areas, and those who teach and train others in the field. Chapter 1 contains introductory material. Radiometry is covered in Chapter 2. The author examines Thermal detectors in Chapter 3; the “Classical” photon detectors – simple photoconductors and photovoltaics in Chapter 4; and “Modern Photon Detectors” in Chapter 5. Chapters 6 through 8 consider respectively individual elements and small arrays of elements the “readouts” (ROICs) used with large imaging arrays; and Electronics for FPA Operation and Testing. The Test Set and The Testing Process are analyzed in Chapters 9 and 10, with emphasis on uncertainty and trouble shooting. Chapters 11 through 15 discuss related skills, such as Uncertainty, Cryogenics, Vacuum, Optics, and the use of Fourier Transforms in the detector business. Some highlights of this new edition are that it Discusses radiometric nomenclature and calculations, detector mechanisms, the associated electronics, how these devices are tested, and real-life effects and problems Examines new tools in Infrared detector operations, specifically: selection and use of ROICs, electronics for FPA operation, operation of single element and very small FPAs, microbolometers, and multi-color FPAs Contains five chapters with frequently sought-after information on related subjects, such as uncertainty, optics, cryogenics, vacuum, and the use of Fourier mathematics for detector analyses Fundamentals of Infrared and Visible Detector Operation and Testing, Second Edition, provides the background and vocabulary necessary to help readers understand the selection, operation, and testing of modern infrared devices.

Many clergy and churches are now taking to the internet and social media to promote their churches or ministries, but few have thought through some of the difficult pastoral and theological issues that may arise. 'Virtual vicar' Revd Pam Smith guides both new and experienced practitioners through setting up online ministries and considers some of the issues that may arise, such as: Are relationships online as valid as those offline? Is it possible to participate in a 'virtual' communion service? How do you deal with 'trolls' in a Christian way? What is it appropriate for a clergyperson to say on social media?

Modern x-ray data, available through online archives, are important for many astronomical topics. However, using these data requires specialized techniques and software. Written for graduate students, professional astronomers and researchers who want to start working in this field, this book is a practical guide to x-ray astronomy. The handbook begins with x-ray optics, basic detector physics and CCDs, before focussing on data analysis. It introduces the reduction and calibration of x-ray data, scientific analysis, archives, statistical issues and the particular problems of highly extended sources. The book describes the main hardware used in x-ray astronomy, emphasizing the implications for data analysis. The concepts behind common x-ray astronomy data analysis software are explained. The appendices present reference material often required during data analysis.

The guide arose from a survey of UK users and manufacturers/developers to assess detector equipment usage and calibration, in order to identify the factors influencing the accuracy of measurements obtained with detector array equipment, and thus develop calibration techniques and establish best practice procedures. The text contains both a review of the existing literature and a large amount of new experimental data obtained during the course of the study. The main emphasis has been on UV, visible, and near-infrared systems that use silicon detector technology, but the issues arising in thermal imaging with infrared detector arrays have also been addressed, along with brief sections on EM CCDs for low-light-level imaging and on lag effects in CMOS active pixel sensors.

This book constitutes the thoroughly refereed post-proceedings of the First International CLEAR 2006 Evaluation Campaign and Workshop on Classification of Events, Activities and Relationships for evaluation of multimodal technologies for the perception of humans, their activities and interactions. The workshop was held in the UK in April 2006. The papers were carefully reviewed and selected for inclusion in the book.
