Book excerpt: Promoting the design, application and evaluation of visually and electrically effective LED light sources and luminaires for general indoor lighting as well as outdoor and vehicle lighting, this book combines the knowledge of LED lighting technology with human perceptual aspects for lighting scientists and engineers. After an introduction to the human visual system and current radiometry, photometry and color science, the basics of LED chip and phosphor technology are described followed by specific issues of LED radiometry and the optical, thermal and electric modeling of LEDs. This is supplemented by the relevant practical issues of pulsed LEDs, remote phosphor LEDs and the aging of LED light sources. Relevant human visual aspects closely related to LED technology are described in detail for the photopic and the mesopic range of vision, including color rendering, binning, whiteness, Circadian issues, as well as flicker perception, brightness, visual performance, conspicuity and disability glare. The topic of LED luminaires is discussed in a separate chapter, including retrofit LED lamps, LED-based road and street luminaires and LED luminaires for museum and school lighting. Specific sections are devoted to the modularity of LED luminaires, their aging and the planning and evaluation methods of new LED installations. The whole is rounded off by a summary and a look towards future developments.

Available in PDF, EPUB and Kindle. Book excerpt: Measuring Stress is the definitive resource for health and social scientists interested in assessing stress in humans. With contributions from leading experts, this work provides for the first time a unified conceptual overview of the intricate relationship between stress and a variety of disorders. Its interdisciplinary approach to the selection of appropriate environmental, psychological, and biological measures includes comprehensive evaluations and practical advice regarding a wide range of measurement approaches. For environmental stress, techniques such as checklists and interviews that measure life event, daily event, and chronic stress are discussed. An analysis of psychological measurements includes methods for assessing stress appraisal and affective response. Neuroendocrine, cardiovascular, and immune measures are examined as important biological stress assessments. Contributors also uncover the conceptual underpinnings of each approach as well as the various costs and benefits of available assessment techniques. Reflecting the diversity of theoretical conceptions of stress, Measuring Stress masterfully provides integrative, incisive guidelines that will prove invaluable to students, clinicians, and researchers in health and social psychology, medicine, nursing, epidemiology, sociology, and psychiatry.

This book was released on 2023-01-23 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the significant aspects of thermal transient testing, the most important method of thermal characterization of electronics available today. The book presents the theoretical background of creating structure functions from the measured results with mathematical details. It then shows how the method can be used for thermal qualification, structure integrity testing, determining material parameters, and calibrating simulation models. General practical questions about measurements are discussed to help beginners carry out thermal transient testing. The particular problems and tricks of measuring with various electronic components, such as Si diodes, bipolar transistors, MOS transistors, IGBT devices, resistors, capacitors, wide bandgap materials, and LEDs, are covered in detail with the help of various use cases. This hands-on book will enable readers to accomplish thermal transient testing on any new type of electronics and provides the theoretical details needed to understand the opportunities and limitations offered by the methodology. The book will be an invaluable reference for practicing engineers, students, and researchers.

This book was released on 2008-06-19 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: In engineering design and development, reliable and accurate computational methods are requested to replace or complement expensive and time consuming experimental trial and error work. Tremendous advancements have been achieved during recent years due to improved numerical solutions of non-linear partial differential equations and computer developments to achieve efficient and rapid calculations. Nevertheless, to further progress in computational methods will require developments in theoretical and predictive procedures – both basic and innovative – and in applied research. Accurate experimental investigations are needed to validate the numerical calculations. This book contains the edited versions of the papers presented at the Tenth International Conference on Advanced Computational Methods and Experimental Measurements in Heat Transfer and Mass Transfer held in Maribor, Slovenia in July 2008. The objective of this conference series is to provide a forum for presentation and discussion of advanced topics, new approaches and application of advanced computational methods and experimental measurements to heat and mass transfer problems. The contributed papers are grouped in the following appropriate sections to provide better access for readers: Natural and forced convection; Heat exchangers; Advances in computational methods; Heat recovery; Heat transfer; Modelling and experiments.

Download or read book Pathways Towards Effective Locally Led Development Co-operation Learning by Example written by OECD and published by OECD Publishing. This book was released on 2024-09-20 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: As more providers commit to support locally led development – whereby local actors have agency in framing, design, delivery, learning and accountability – this peer learning synthesis report provides a comprehensive overview of their efforts and strives to develop a common understanding and definition of locally led development co-operation. Building on existing practices, the report analyses to what extent providers’ systems can enhance or hinder the agency of local actors, looking in particular at policies, financing mechanisms, partnerships, and management processes. Rather than prescribing a singular pathway, it emphasises the importance of context-specific, sequenced, and locally defined approaches. Pathways Towards Effective Locally Led Development Co-operation: Learning by Example is a useful read for policymakers, practitioners and anyone committed to more equitable and effective development co-operation.
