  2. 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 ...

    en.wikipedia.org/wiki/Tax_Deduction_and...

    The Tax Deducted at Source (TDS) on payments made by assessees is deposited under the TAN to enable the assessees who have received the payments to claim the tax deducted in their income tax return. ApplicationTAN is applied through "Form No. 49B" (prescribed under Indian Income Tax Law). A completed form can be submitted online at the NSDL ...

  4. 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 ...

  5. Trace fossil classification - Wikipedia

    en.wikipedia.org/wiki/Trace_fossil_classification

    Trace fossils are classified in various ways for different purposes. Traces can be classified taxonomically (by morphology), ethologically (by behavior), and toponomically, that is, according to their relationship to the surrounding sedimentary layers. Except in the rare cases where the original maker of a trace fossil can be identified with ...

    The Trade Control and Expert System (TRACES), is a web-based veterinarian certification tool used by the European Union for controlling the import and export of live animals and animal products within and without its borders. Its network falls under the responsibility of the European Commission. TRACES constitutes a key element of how the ...

  7. 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.

  8. Transderivational search - Wikipedia

    en.wikipedia.org/wiki/Transderivational_search

    Transderivational search. Transderivational search (often abbreviated to TDS) is a psychological and cybernetics term, meaning when a search is being conducted for a fuzzy match across a broad field. In computing the equivalent function can be performed using content-addressable memory.

  9. 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 ...
