3. Ground-penetrating radar - Wikipedia

   en.wikipedia.org/wiki/Ground-penetrating_radar

   Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables or masonry. [ 1 ]

4. Polymer stabilizer - Wikipedia

   en.wikipedia.org/wiki/Polymer_stabilizer

   Light stabilizer are used to inhibit polymer photo-oxidation, which is the combined result of the action of light and oxygen. Like autoxidation this is a free radical process, hence the antioxidants described above are effective inhibiting agents, however additional classes of additives are also beneficial, such as UV absorbers, quenchers of ...

5. Gunshot residue - Wikipedia

   en.wikipedia.org/wiki/Gunshot_residue

   Organic residues can come from propellants like nitrocellulose and trinitrotoluene, plasticisers like triacetin, stabilizers like diphenylamine and possible reaction products of said compounds. [2] The persistence of these residues is quite low compared to inorganic GSR, with very little quantities of carryover (if any).

6. Anti-rolling gyro - Wikipedia

   The World War I transport USS Henderson, completed in 1917, was the first large ship with gyro stabilizers. It had two 25-ton, 9-foot (2.7 m) diameter flywheels mounted near the center of the ship, spun at 1100 rpm by 75 hp (56 kW) AC motors.

7. Stabilizer (aeronautics) - Wikipedia

   A Boeing 737 uses an adjustable stabilizer, moved by a jackscrew, to provide the required pitch trim forces. Generic stabilizer illustrated. A horizontal stabilizer is used to maintain the aircraft in longitudinal balance, or trim: [3] it exerts a vertical force at a distance so the summation of pitch moments about the center of gravity is zero.

   The Defense Advanced GPS Receiver (DAGR). Coordinates are for Rockwell Collins headquarters in Cedar Rapids, Iowa.. The AN/PSN-13 Defense Advanced GPS Receiver (DAGR; colloquially, "dagger") is a handheld GPS receiver used by the United States Department of Defense and select foreign military services.

9. Gyroscopic stabilizer - Wikipedia

   en.wikipedia.org/wiki/Gyroscopic_stabilizer

   A Gyroscopic stabilizer is a control system that reduces tilting movement of a ship or aircraft. It senses orientation using a small gyroscope, and counteracts rotation by adjusting control surfaces or by applying force to a large gyroscope. It can be: Some active ship stabilizers adjust "active fins" of the ship or apply force to a large ...
