Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Setting Priorities for Large Research Facility Projects Supported by the National Science Foundation written by National Research Council and published by National Academies Press. This book was released on 2004-07-15 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1995, the National Science Foundation (NSF) created a special account to fund large (several tens of millions of dollars) research facilities. Over the years, these facilities have come to represent an increasingly prominent part of the nation's R&D portfolio. Recently concern has intensified about the way NSF is selecting projects for this account. In 2003, six U.S. Senators including the chair and ranking member of the Senate Subcommittee on VA, HUD, and Independent Agencies Appropriations expressed these concerns in a letter to the NRC asking it to "review the current prioritization process and report to us on how it can be improved." This report presents a series of recommendations on how NSF can improve its priority setting process for large research facilities. While noting that NSF has improved this process, the report states that further strengthening is needed if NSF is to meet future demands for such projects.

Download or read book Technical Debt in Practice written by Neil Ernst and published by MIT Press. This book was released on 2021-08-17 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: The practical implications of technical debt for the entire software lifecycle; with examples and case studies. Technical debt in software is incurred when developers take shortcuts and make ill-advised technical decisions in the initial phases of a project, only to be confronted with the need for costly and labor-intensive workarounds later. This book offers advice on how to avoid technical debt, how to locate its sources, and how to remove it. It focuses on the practical implications of technical debt for the entire software life cycle, with examples and case studies from companies that range from Boeing to Twitter. Technical debt is normal; it is part of most iterative development processes. But if debt is ignored, over time it may become unmanageably complex, requiring developers to spend all of their effort fixing bugs, with no time to add new features--and after all, new features are what customers really value. The authors explain how to monitor technical debt, how to measure it, and how and when to pay it down. Broadening the conventional definition of technical debt, they cover requirements debt, implementation debt, testing debt, architecture debt, documentation debt, deployment debt, and social debt. They intersperse technical discussions with "Voice of the Practitioner" sidebars that detail real-world experiences with a variety of technical debt issues.

Available in PDF, EPUB and Kindle. Book excerpt: Transactions XXVIA of the International Astronomical Union (IAU) provides a comprehensive and authoritative review of what has been achieved in astronomy during the years 2003 to 2005. The insightful and up-to-date reviews are written by the Presidents and Chairpersons of the IAU's different Divisions, Commissions and Working Groups and each focuses on a different subject area. Topics covered in this wide-ranging volume include: fundamental astronomy; the Sun and heliosphere; planetary systems sciences; stars; variable stars; interstellar matter; the Galactic system; galaxies and the Universe; optical and infrared techniques; radio astronomy; space and high energy astrophysics; and other IAU activities. The reviews are written at a level suitable for colleagues in the same field, but they will also be useful for students and researchers wishing to gain an overview beyond their own research area.

Download or read book Going Big written by Christopher W. Stubbs and published by MIT Press. This book was released on 2024-03-19 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: All the crucial skills scientists need to make a professional transition into large projects and collaborations that require governance and project management. Modern science increasingly tackles ambitious projects whose size and complexity require an equally ambitious coordination of efforts, schedules, and resources. In Going Big, Harvard Professor and Dean of Science Christopher Stubbs provides the essential resource for scientists who are ramping up the scale of their scientific enterprises and working within the various hierarchies and sociologies of large scientific teams. An experienced project scientist, Stubbs focuses on technical project management for the construction of large facilities, instruments, and software development, and guides both junior and established scientists on how to work in big, structured collaborations. Stubbs supplements scientists’ formal training in their fields with the logistical, sociological, and strategic knowledge they need to tackle modern science’s increasingly ambitious projects, from matters of risk, cost, and performance to the issues of budgeting, scheduling, and human relations. Chapters address technical documentation, risk mitigation, tracking progress and milestones; health, safety, and environmental considerations; and ways to be an effective team member and defuse interpersonal conflicts. Scaffolded with real-world advice and suggestions for success, Going Big covers the lifecycle of large projects to equip scientists worldwide, at every stage of their career.
