A test pattern generation method with high compression ratio

IEICE Electronics Express, 2011
This paper proposes a test pattern generation and compression method to reduce test volume for VLSI testing. Unlike traditional approaches, the proposed scheme predefines linear relationships between vectors or within a vector of a test sequence firstly. Then, it determines test patterns by fault simulation.

Experimental study of locally loaded timber in compression perpendicular to the grain [PDF]

, 2011
Since the test method for compression strength perpendicular to the grain was changed from a partial area to a full area loading test, strength values for softwood in EN 338 were significantly reduced.

Generation, amplification, and nonlinear self-compression of powerful superradiance pulses [PDF]

, 2012
Superradiance (SR) of electron bunches can be considered an effective method of production of ultrashort electromagnetic pulses. Different types of SR associated with different mechanisms (cyclotron, Cherenkov, and bremsstrahlung) of stimulated emission ...
