Loudspeaker system figures of merit
IEEE Transactions on Audio and Electroacoustics, 1973The loudspeaker system small-signal figure of merit is a useful performance criterion that must be evaluated and used with some care. In practice, this figure of merit is significantly reduced by enclosure dissipation, including that contributed by filling materials.

ALTERNATIVE FIGURES-OF-MERIT IN DIGITAL MAMMOGRAPHY
Radiation Protection Dosimetry, 2017The aim of this study is to explore the use of a quality (Q) factor in digital mammography as a figure-of-merit. Q factors take a reference value into account and can be compared to a theoretical value. They are also intended to summarise the performance of any unit based on a number.

Figure of merit for thermoelectrics
Journal of Applied Physics, 1989Theoretical calculations are presented for the figure of merit Z in thermoelectrics. The maximum values of Z are obtained in semiconductors which are doped so that the chemical potential is near the band edge. The highest Z is related to the B parameter of Chasmar and Stratton [J. Electron. Control 7, 52 (1959)].

ACM SIGACT News, 1990
Science has marched on despite the appearance of the original "Figures of Merit" [18]. The purpose of this survey is to bring the community up to date on the most recent bounds, so that we may collaborate to improve them.

Thermoelectric figure of merit of superlattices
Applied Physics Letters, 1994We calculate the electrical conductivity, thermopower, and the electronic contribution to the thermal conductivity of a superlattice, with the electric field and the thermal gradient applied parallel to the interfaces. We include the tunneling between quantum wells.

Thermomagnetic Figure of Merit: Bismuth
Journal of Applied Physics, 1963The asymptotic value of the isothermal thermomagnetic figure of merit is obtained for a two-band multivalleyed semiconductor or semimetal where the concentration of holes and electrons is equal. The bismuth band structure is used as a specific model. It is shown that at strong magnetic fields the isothermal Nernst coefficient Njii is independent of the

Stretchable Figures of Merit in Deformable Electronics
Advanced Materials, 2015Stretchable electronic systems accommodate strain in various ways-from the intrinsic mechanical properties, through composite structures, by the formation of cracks, or with other mechanisms. This has produced some imprecision in the literature on what is meant by the term "stretchable."
