For common tape measurements, the tape used is a steel tape with coefficient of thermal expansion C equal to 0.000,011,6 units per unit length per degree Celsius change. This means that the tape changes length by 1.16 mm per 10 m tape per 10 °C change from the standard temperature of the tape.
By coherent reorganization of the data from all the pings, a synthetic-aperture image is produced with improved along-track resolution. In contrast to conventional side-scan sonar (SSS), SAS processing provides range-independent along-track resolution. At maximum range the resolution can be magnitudes better than that of side-scan sonars. [2]
SDLT adds an optical servo system that reads servo patterns on the back of the tape to keep the data tracks on the front of the tape correctly aligned with the read/write heads. This is important for newer tape media, which have very thin, dense data tracks; 256, 384 and 768 data tracks on a 1 ⁄ 2 -inch-wide (13 mm) tape are available.
Businesswoman and philanthropist Michele Kang just made a historic donation to women’s soccer. Kang, owner of the professional soccer team Washington Spirit, has pledged $30 million to the girls ...
The tape is 0.75 in (19 mm) wide, accommodating 6 data tracks, 2 mark tracks, and 2 clock tracks, with data recorded at roughly 350 bits per inch (138 bits per cm). Each track is paired with a non-adjacent track for redundancy by wiring the tape heads in parallel; as a result the electronics only deal with 5 tracks: a clock track, a mark track ...
Young girls have long been a vulnerable group. But in the past few years, alarming trends have been witnessed that need to be swiftly addressed by families, communities, and society as a whole.
A U.K. woman had her breast cancer detected through AI after a routine mammogram came back as normal. Experts Drs. Nicole Saphier and Harvey Castro discuss the power of AI in cancer care.
A loosely riveted hook lets a tape measure measure inner (1) and outer (2) lengths. Measuring tapes designed for carpentry or construction often use a curved metallic ribbon that can remain stiff and straight when extended, but can also retract into a coil for convenient storage. This type of tape measure will have a hook on the end to aid ...
