Another refinement of the slimline PlayStation 2 (SCPH-9000x) was released in Japan on November 22, 2007. [8] As well as some cosmetic changes, the design of the hardware was overhauled, incorporating the power supply into the console itself like the original (fat) PlayStation 2 revisions; this also increases the total weight to 720 grams (25 oz).
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.

Real cassette tapes invariably deviate from the references and require fine tuning of bias; recording a tape with improper bias increases distortion and alters frequency response. [26] A 1990 comparative test of 35 Type I tapes showed that their optimal bias levels were within 1 dB of the Type I reference, while Type IV tapes deviated from the ...
An asymmetric funnel indicates a relationship between treatment effect estimate and study precision. This suggests the possibility of either publication bias or a systematic difference between studies of higher and lower precision (typically ‘small study effects’). Asymmetry can also arise from use of an inappropriate effect measure.

Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion.As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here.
