  2. Time-domain reflectometer - Wikipedia

    en.wikipedia.org/wiki/Time-domain_reflectometer

    Time-domain reflectometer for cable fault detection. A time-domain reflectometer (TDR) is an electronic instrument used to determine the characteristics of electrical lines by observing reflected pulses. It can be used to characterize and locate faults in metallic cables (for example, twisted pair wire or coaxial cable), [1] and to locate ...

  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. Tax deduction at source - Wikipedia

    en.wikipedia.org/wiki/Tax_deduction_at_source

    Tax deduction at source. Tax deduction at source (TDS) is an Indian withholding tax that is a means of collecting tax on income, dividends, or asset sales by requiring the payer (or legal intermediary) to deduct tax due before paying the balance to the payee (and the tax to the revenue authority). Under the Indian Income Tax Act of 1961, income ...

    The route follows the Tour du Mont Blanc hiking path that is usually completed in 7 to 9 days by hikers. This is a loop around Mont Blanc.. It starts from Chamonix (1,035 m) and goes up to the Col de Voza (1,653 m) to reach Les Contamines (1,150 m), which is the first life base.

  7. 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 ...

  8. Total dissolved solids - Wikipedia

    en.wikipedia.org/wiki/Total_dissolved_solids

    Total dissolved solids (TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular (colloidal sol) suspended form. TDS are often measured in parts per million (ppm). TDS in water can be measured using a digital meter.
