Mechanical and Electronic Packaging for a Launch-Vehicle Guidance Computer
The packaging design of a launch-vehicle guidance computer is described. The computer uses microminiature technology, of which the basic module is a... -
Nonblackbody Radiation
None of the natural or artificial objects that we may encounter is a perfectly black body. For example, “black” paper reflects 4.5% of the energy... -
Group analysis of domains and domain pairs
Basic symmetry properties of transformation twins and of ferroelectric or ferromagnetic domains are examined in terms of the abstract group theory....
