This bibliography contains abstracts for 297 reports, articles, and other documents introduced into the NASA scientific and technical information system in February 1980
Mechanical Engineering
The book substantially offers the latest progresses about the important topics of the "Mechanical Engineering" to readers. It includes twenty-eight excellent studies prepared using state-of-art methodologies by professional researchers from different countries. The sections in the book comprise of the following titles: power transmission system, manufacturing processes and system analysis, thermo-fluid systems, simulations and computer applications, and new approaches in mechanical engineering education and organization systems
Improving aircraft performance using machine learning: a review
This review covers the new developments in machine learning (ML) that are
impacting the multi-disciplinary area of aerospace engineering, including
fundamental fluid dynamics (experimental and numerical), aerodynamics,
acoustics, combustion and structural health monitoring. We review the state of
the art, gathering the advantages and challenges of ML methods across different
aerospace disciplines and provide our view on future opportunities. The basic
concepts and the most relevant strategies for ML are presented together with
the most relevant applications in aerospace engineering, revealing that ML is
improving aircraft performance and that these techniques will have a large
impact in the near future
A cumulative index to Aeronautical Engineering: A continuing bibliography
This bibliography is a cumulated index to the abstracts contained in NASA SP-7037(132) through NASA SP-7037(143) of Aeronautical Engineering: A continuing bibliography. NASA SP-7037 and its supplements have been compiled through the cooperative efforts of the American Institute of Aeronautics and Astronautics (AIAA) and the National Aeronautics and Space Administration (NASA). This cumulative index includes subject, personal author, corporate source, contract, and report number indexes
Cumulative index to NASA Tech Briefs, 1986-1990, volumes 10-14
Tech Briefs are short announcements of new technology derived from the R&D activities of the National Aeronautics and Space Administration. These briefs emphasize information considered likely to be transferrable across industrial, regional, or disciplinary lines and are issued to encourage commercial application. This cumulative index of Tech Briefs contains abstracts and four indexes (subject, personal author, originating center, and Tech Brief number) and covers the period 1986 to 1990. The abstract section is organized by the following subject categories: electronic components and circuits, electronic systems, physical sciences, materials, computer programs, life sciences, mechanics, machinery, fabrication technology, and mathematics and information sciences
A Comprehensive Review of Digital Twin -- Part 1: Modeling and Twinning Enabling Technologies
As an emerging technology in the era of Industry 4.0, digital twin is gaining
unprecedented attention because of its promise to further optimize process
design, quality control, health monitoring, decision and policy making, and
more, by comprehensively modeling the physical world as a group of
interconnected digital models. In a two-part series of papers, we examine the
fundamental role of different modeling techniques, twinning enabling
technologies, and uncertainty quantification and optimization methods commonly
used in digital twins. This first paper presents a thorough literature review
of digital twin trends across many disciplines currently pursuing this area of
research. Then, digital twin modeling and twinning enabling technologies are
further analyzed by classifying them into two main categories:
physical-to-virtual, and virtual-to-physical, based on the direction in which
data flows. Finally, this paper provides perspectives on the trajectory of
digital twin technology over the next decade, and introduces a few emerging
areas of research which will likely be of great use in future digital twin
research. In part two of this review, the role of uncertainty quantification
and optimization are discussed, a battery digital twin is demonstrated, and
more perspectives on the future of digital twin are shared
