Today's magnetic resonance imaging machinesuse superconductor magnetsto achieve themagnetic field strengthof a few teslas, which is needed for accurate imaging. For comparison, the Earth's magnetic field has a strength, or flux density, of about 50 microteslas. The magnetic field produced by ...

摘要:Everyone In The Electrical Industry, including the electrical apprentice, the journeyman, the master electrician, electrical contractor, electrical engineer, designer, the electrical inspector, et al., seem to use the phrase "neutral conductor." However, until the 2008 National Electrical Code (...
So, if there was an outside engineer, you would be the guy who would help get things rolling? Exactly. That happened quite a bit in the first year. Everyone had heard about the studio and was excited to check it out. They would come and record in this big room. I'd show them how...
Although the technology is rapidly advancing [60], laptop-sized plants (e.g., 30-50 W-hr), have tended to be in an awkward place for fuel cells - too big to directly power with micro cells, but small enough that the overhead in mass needed to handle the standard fuel ...
October 2007 conference, an audience member declared that McCullough's employer, the U.S. Department of Energy (DOE), is "taming the Wild West" and suggested that he wear a cowboy hat. McCullough, LC, CLEP, is a senior research engineer for the DOE's Pacific Northwest National Laboratory...

Electrical machines used in aviation operate during flight at high altitudes and, therefore, low temperatures. However, at the design stage, the engineer selects the right type and parameters of machine components for the operating environment, the proper lubricant, and many other parameters. Low ...
Detailed bibliometric and scientometric research will be needed to focus on the different indicators. Moreover, other software tools such as CiteSpace (which also removes duplicates or publications with an unclear year of publication) can be used for an in-depth visualization [37]. We adopted VOS...
The first data treatment approach was conducted by a senior engineer at the steel plant. This data treatment was done by manually inspecting each row of the data set and flagging rows which contained values that were not consistent with the data instance as a whole. This data treatment is a...
