Book Description
The objective of this internal research and development (IRAD)-funded campaign by Aerodyne Research, Inc. was to demonstrate the field-worthiness and assess the performance of a real-time cloud optical depth (COD) sensor (dubbed three-waveband spectrally-agile technique [TWST]) through a side-by-side comparison with proven, ground-based operational sensors currently deployed at the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility Mobile Facility (AMF) site on the Cape Cod National Seashore for the Two-Column Aerosol Project (TCAP). We anticipated direct comparisons with the Aerosol Robotic Network (AERONET; when in cloud mode) and SAS instruments and expected ancillary data from other sensors such as the Total Sky Imager, the Scanning Cloud Radar, and the Microwave Radiometer to facilitate and validate these comparisons. Because the cloud optical depth retrieval algorithms used by AERONET, solar array spectrometer (SAS), and TWST are totally independent, this deployment provided a unique opportunity to evaluate the field performance of TWST. If the effort proves successful, it may qualify TWST for operational service or additional evaluation effort.

Book Description
It was our aim to place at the disposal of radiologists within a short time an atlas of high-quality, valuable pictures of abdominal CT without We felt that, the image degradation inherent to slower scanning apparatus. notwithstanding rapid evolution in CT scanning apparatus and the resulting rapid advances in our clinical knowledge about the value, limitations and applications of this new diagnostic imaging modality, an effort should be made to realize an atlas of reference. From more than 7,000 patients studied with abdominal CT, we tried to assemble images with maximal anatomical detail, which implies the use of large window settings, being well aware that in daily routine practice basic CT methodology includes the use of different window settings for optimal information. It was, however, a conscious decision not to use comparative images with large and small window settings in order to stay within a reasonable total number of figures. Much emphasis has been placed upon the use of contrast enhancement by intravenous contrast media. This is based on the conviction that essen tially new and better morphological information about normal and pathological processes within the abdomen can be obtained because short exposure times now allow one to capture the rapidly changing aspect and degree of contrast enhancement of the lesions as a function of their vascu larity.

Book Description
Magnetospheric Imaging: Understanding the Space Environment through Global Measurements is a state-of-the-art resource on new and advanced techniques and technologies used in measuring and examining the space environment on a global scale. Chapters detail this emergent field by exploring optical imaging, ultraviolet imaging, energetic neutral atom imaging, X-ray imaging, radio frequency imaging, and magnetic field imaging. Each technique is clearly described, with details about the technologies involved, how they work, and both their opportunities and limitations. Magnetospheric imaging is still a relatively young capability in magnetospheric research, hence this book is an ideal resource on this burgeoning field of study. This book is a comprehensive resource for understanding where the field stands, as well as providing a stepping stone for continued advancement of the field, from developing new techniques, to applying techniques on other planetary bodies. - Summarizes and reviews significant progress in the field of magnetospheric imaging - Covers all of the techniques and technologies available, including a basic overview of each, as well as what it can accomplish, how it works, what its limitations are, and how it might be improved - Details ways for measuring the space environment on a global scale, what physical measurements various technologies can provide, and how they can be effectively used

Book Description
Direct-Write Technologies covers applications, materials, and the techniques in using direct-write technologies. This book provides an overview of the different direct write techniques currently available, as well as a comparison between the strengths and special attributes for each of the techniques. The techniques described open the door for building prototypes and testing materials. The book also provides an overview of the state-of-the-art technology involved in this field. Basic academic researchers and industrial development engineers who pattern thin film materials will want to have this text on their shelves as a resource for specific applications. Others in this or related fields will want the book to read the introductory material summarizing isuses common to all approaches, in order to compare and contrast different techniques. Everyday applications include electronic components and sensors, especially chemical and biosensors. There is a wide range of research and development problems requiring state-of-the-art direct write tools. This book will appeal to basic researchers and development engineers in university engineering departments and at industrial and national research laboratories. This text should appeal equally well in the United States, Asia, and Europe. Both basic academic researchers and industrial development engineers who pattern thin film materials will want to have this text on their shelves as a resource for specific applications. An overview of the different direct write techniques currently available A comparison between the strengths and special attributes for each of the techniques An overview of the state-of-the-art technology involved in this field
