2. Robotic vacuum cleaner - Wikipedia

   en.wikipedia.org/wiki/Robot_vacuum_cleaner

   Automation. A robotic vacuum cleaner, sometimes called a robovac or a roomba as a generic trademark, is an autonomous robotic vacuum cleaner which has a limited vacuum floor cleaning system combined with sensors and robotic drives with programmable controllers and cleaning routines. Early designs included manual operation via remote control and ...

3. Terahertz time-domain spectroscopy - Wikipedia

   en.wikipedia.org/wiki/Terahertz_time-domain...

   In physics, terahertz time-domain spectroscopy ( THz-TDS) is a spectroscopic technique in which the properties of matter are probed with short pulses of terahertz radiation. The generation and detection scheme is sensitive to the sample's effect on both the amplitude and the phase of the terahertz radiation. Fourier transform of the above pulse.

4. Naval Tactical Data System - Wikipedia

   NTDS training in a mock-up of a shipboard CIC. Naval Tactical Data System ( NTDS) was a computerized information processing system developed by the United States Navy in the 1950s and first deployed in the early 1960s for use in combat ships. It took reports from multiple sensors on different ships and collated it to produce a single unified ...

   304L stainless steel, a low-carbon variant of 304 steel, is used for ultra-high vacuum systems. 316L stainless steel a low-carbon and low-magnetic stainless steel, used in accelerator technologies. 347 stainless steel does not accept high polish. 321 stainless steel is chosen when low magnetic permeability is needed.

6. Thermal desorption spectroscopy - Wikipedia

   en.wikipedia.org/wiki/Thermal_desorption...

   Temperature programmed desorption (TPD) is the method of observing desorbed molecules from a surface when the surface temperature is increased. When experiments are performed using well-defined surfaces of single-crystalline samples in a continuously pumped ultra-high vacuum (UHV) chamber, then this experimental technique is often also referred to as thermal desorption spectroscopy or thermal ...

7. Vacuum engineering - Wikipedia

   en.wikipedia.org/wiki/Vacuum_engineering

   Vacuum engineering. Vacuum engineering is the field of engineering that deals with the practical use of vacuum in industrial and scientific applications. Vacuum may improve the productivity and performance of processes otherwise carried out at normal air pressure, or may make possible processes that could not be done in the presence of air.
