Étude Op. 25, No. 6, in G-sharp minor, is a technical study composed by Frédéric Chopin focusing on thirds, trilling them at a high speed. Also called the Double Thirds Étude, it is considered one of the hardest of Chopin's 24 Études , ranking the highest level of difficulty according to the Henle difficulty rankings .
Roger Billings of Provo, Utah, founded Billings Computer in early 1977, four years after incorporating parent company Billings Energy Corporation. [2] Billings Energy was a hydrogen fuel company that served as a springboard for Roger Billings and his associates' research; in the 1960s, the former earned a scholarship to Brigham Young University after winning an international high school ...
The three regions include the cryogenic instrument module (1), the electronics compartment (2), and finally the Command and Data Handling subsystem and MIRI crycooler (3), which is inside the spacecraft bus physically. [1] MIRI needs to be colder than the other instruments so it has an additional cooler. [1] MIRI is the mid-infrared instrument. [1]
COBOL (/ ˈ k oʊ b ɒ l,-b ɔː l /; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is an imperative, procedural, and, since 2002, object-oriented language.
TransHab was a program pursued by NASA in the late 1990s to develop the technology for expandable habitats inflated by air in space. TransHab was intended as a replacement for the existing rigid International Space Station crew Habitation Module.
The isomorphism theorems for vector spaces (modules over a field) and abelian groups (modules over ) are special cases of these. For finite-dimensional vector spaces, all of these theorems follow from the rank–nullity theorem. In the following, "module" will mean "R-module" for some fixed ring R.
Nanosolar's solar cells were verified by NREL to be as efficient as 14.6% in 2006, [21] 15.3% in 2009, [22] and 17.1% in 2011. [23] Efficiencies for then-current production panels were said to be 8-9%, with plans to submit panels with 10-11% efficiency for IEC certification in the fall of 2010.
A period 6 element is one of the chemical elements in the sixth row (or period) of the periodic table of the chemical elements, including the lanthanides.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behaviour of the elements as their atomic number increases: a new row is begun when chemical behaviour begins to repeat, meaning that elements ...
