  2. Differential scanning calorimetry - Wikipedia

    en.wikipedia.org/wiki/Differential_scanning...

    Differential scanning calorimetry ( DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. [1] Both the sample and reference are maintained at nearly the same temperature throughout the experiment.

  3. Tantalum nitride - Wikipedia

    en.wikipedia.org/wiki/Tantalum_nitride

    Tantalum nitride (TaN) is a chemical compound, a nitride of tantalum. There are multiple phases of compounds, stoichimetrically from Ta 2 N to Ta 3 N 5, including TaN. As a thin film TaN find use as a diffusion barrier and insulating layer between copper interconnects in the back end of line of computer chips. Tantalum nitrides are also used in ...

  4. Tax Deduction and Collection Account Number - Wikipedia

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

    A TAN application should accompany a 'proof of identity' and a 'proof of address' (photocopies) of the deductor. In the case of online applications, these documents need to be sent over mail (post/courier) to NSDL - TAN Application division. When NSDL receives the TAN application along with said documents (either through TIN FC / Online), the ...

  5. Dynamic mechanical analysis - Wikipedia

    en.wikipedia.org/wiki/Dynamic_mechanical_analysis

    Differential thermal analysis. Dielectric thermal analysis. Dynamic mechanical analysis (abbreviated DMA) is a technique used to study and characterize materials. It is most useful for studying the viscoelastic behavior of polymers. A sinusoidal stress is applied and the strain in the material is measured, allowing one to determine the complex ...

  6. Evolved gas analysis - Wikipedia

    en.wikipedia.org/wiki/Evolved_gas_analysis

    Evolved gas analysis ( EGA) is a method used to study the gas evolved from a heated sample that undergoes decomposition or desorption. It is either possible just to detect evolved gases using evolved gas detection (EGD) or to analyse explicitly which gases evolved using evolved gas analysis (EGA). [1] Therefore different analytical methods can ...

  7. List of trigonometric identities - Wikipedia

    en.wikipedia.org/wiki/List_of_trigonometric...

    These identities are useful whenever expressions involving trigonometric functions need to be simplified. An important application is the integration of non-trigonometric functions: a common technique involves first using the substitution rule with a trigonometric function, and then simplifying the resulting integral with a trigonometric identity.

  8. Law of tangents - Wikipedia

    en.wikipedia.org/wiki/Law_of_tangents

    Trigonometry. In trigonometry, the law of tangents or tangent rule [1] is a statement about the relationship between the tangents of two angles of a triangle and the lengths of the opposing sides. In Figure 1, a, b, and c are the lengths of the three sides of the triangle, and α, β, and γ are the angles opposite those three respective sides.

  9. Distributed control system - Wikipedia

    en.wikipedia.org/wiki/Distributed_control_system

    SCADA. v. t. e. A distributed control system ( DCS) is a computerized control system for a process or plant usually with many control loops, in which autonomous controllers are distributed throughout the system, but there is no central operator supervisory control. This is in contrast to systems that use centralized controllers; either discrete ...
