Book Description
The 1991 NRC decadal survey for astronomy and astrophysics included a project called the Millimeter Array (MMA). This instrument would be an array of millimeter-wavelength telescopes intended to capture images of star-forming regions and distant star-burst galaxies. With the addition of contributions form Europe, the MMA evolved into the Atacama Large Millimeter Array (ALMA), a proposed array of 64, 12-meter antennas. The project is now part of the NSF Major Research Equipment and Facilities budget request. Increased costs, however, have forced the NSF to reconsider the number of antennas. To help with that review, NSF asked the NRC to assess the scientific consequences of reducing the number of active antennas from 60 to either 50 or 40. This report presents an assessment of the effect of downsizing on technical performance specifications, performance degradation, and the ability to perform transformational science, and of the minimum number of antennas needed.

Book Description
Currently under construction in Northern Chile, the Atacama Large Millimeter Array (ALMA) is the most ambitious astronomy facility under construction. This book describes the enormous capabilities of ALMA, the state of the project, and most notably the scientific prospects of such a unique facility. The book includes reviews and recent results on most hot topics of modern astronomy. It looks forward to the revolutionary results that are likely to be obtained with ALMA.

Book Description
This dissertation asks the following research question: Which boundary spanning mechanisms affect the effective solution of problems under different organizational contexts? I draw upon problem solving and boundary spanning mechanisms literature to shed light on how communities of knowledge cope with a stream of variable and unpredictable problems under different environments. To empirically answer the research question, I focus on the conception and construction of ALMA - the "Atacama Large Millimeter Array", which is the world's largest, most expensive and most sensitive radio telescope array operating at millimeter wavelengths. I rely upon primary data based on interviews and the digital archive of entries in the knowledge-management software used by ALMA personnel to seek out and share knowledge to solve problems. I add to our understanding about how scientists and engineers employ different mechanisms to transfer and create knowledge to solve heterogeneous problems as they emerge.

Book Description
The Nobeyama Radio Observatory of Nagano, Japan, presents information on the Large Millimeter and Submillimeter Array (LMSA) project. The project will consist of 50 10-m antennas and will be covering observation frequencies from 80 to 800 GHz. The observatory describes the specifications and planned system for the project.
