Development Of A Low-Cost Fine Steering Mirror, Steven R. Wassom, Morgan Davidson
Development Of A Low-Cost Fine Steering Mirror, Steven R. Wassom, Morgan Davidson
Space Dynamics Laboratory Publications
The Space Dynamics Laboratory has used internal funds to develop a prototype low-cost two-axis fine steering mirror (FSM) for space-based and airborne applications. The FSM has a lightweight 75 mm-by- 150-mm high-reflectance mirror, high angular deflection capability for along-track ground motion compensation and cross-track pointing, and a 70-Hertz bandwidth for small amplitudes to help cancel unwanted jitter. It makes use of off-the-shelf components as much as possible. Key performance parameters are: Clear aperture, 75 mm; elevation angle, ±15 deg (mechanical); azimuth angle, ±60 deg (mechanical); slew rate, greater than 75 deg/sec; bandwidth, 70 Hz; steady-state average error, about 1 arcsec; …
Brunswick Me: De-Militarizing The Bnas, Anne Holland, Brett Richardson, Richard Barringer
Brunswick Me: De-Militarizing The Bnas, Anne Holland, Brett Richardson, Richard Barringer
Planning
Closure of the Brunswick Naval Air Station in 2011 will have profound economic impacts on the entire mid-coast Maine region of Maine, with an estimated loss of 6,500 jobs and $330 million annual income. Throughout the Base Realignment and Closure process, Brunswick, the region, and the State of Maine followed federal rules and developed the federally-funded Brunswick Local Redevelopment Authority (BLRA) to plan for reuse of the 3300 acre base. In its planning process, the BLRA adhered to a number of well thought-out Guiding Principles, including the use of extensive public participation and the consideration of “smart growth” principles and …
Professional Development At University: Student Perceptions Of Professional Engineering Practice, Vinay Domal, Brad Stappenbelt, James Trevelyan
Professional Development At University: Student Perceptions Of Professional Engineering Practice, Vinay Domal, Brad Stappenbelt, James Trevelyan
Faculty of Engineering - Papers (Archive)
This study examined student perceptions regarding professional engineering practice. We surveyed secondary school students attending engineering camps, engineering students in their first and fourth years, graduate engineers and experienced engineers to ascertain their impressions about what constitutes the daily activities of a professional engineer. We asked respondents to rate 39 aspects of engineering practice identified from the research later reported in (Trevelyan 2008). These aspects were rated by the participants according to their perception of the importance and the frequency encountered in engineering practice. We also asked where the participants learned or where they believed they were going to learn …
Development Of Plain Carbon And Niobium Microalloyed Ultra-Thin Cast Strip Products Produced By The Castrip® Process, Chris R. Killmore, Harold R. Kaul, Joshua Burg, Kristin R. Carpenter, James G. Williams, Daniel G. Edelman, Peter C. Campbell, Walter N. Blejde
Development Of Plain Carbon And Niobium Microalloyed Ultra-Thin Cast Strip Products Produced By The Castrip® Process, Chris R. Killmore, Harold R. Kaul, Joshua Burg, Kristin R. Carpenter, James G. Williams, Daniel G. Edelman, Peter C. Campbell, Walter N. Blejde
Faculty of Engineering and Information Sciences - Papers: Part B
The CASTRIP facility at Nucor Steel's Crawfordsville, Indiana plant is the world's first commercial installation for production of Ultra-Thin Cast Strip (UCS), via twin-roll strip casting. The facility has been producing plain, low-carbon sheet steel since 2002, with a range of structural grades available. The paper outlines some of the main parameters that influence the final microstructure and resultant mechanical properties of plain, low carbon UCS steels that have been recently made by the CASTRIP process, and then describes new Nb microalloyed UCS products that have been made in the CASTRIP process, significantly expanding the range of thin high strength …
Development Of Hydraulic Fracturing In High Stress Conditions In Australian Underground Coal Mines, Dennis John Black, Naj Aziz
Development Of Hydraulic Fracturing In High Stress Conditions In Australian Underground Coal Mines, Dennis John Black, Naj Aziz
Faculty of Engineering and Information Sciences - Papers: Part A
Hydraulic fracturing has been used extensively in the petroleum and coalbed methane industries as a means of improving access to the reservoir and thereby enhancing production. In the Australian coal mining industry there has been an aversion to the use of hydraulic fracturing. One of the main reasons for the lack of application of this technology has been the perceived risk of damage to the strata and the resulting impact on future mining operations. A number of Australian mines are progressing toward areas where gas drainage is becoming increasingly difficult and these mines are seriously considering the use of hydraulic …
