    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 details are verified and then sent to the Income Tax Department. Once approved, the Department allocates a unique ...

    The bank verifies the TAN submitted against the list of TANs they issued to the user. If it is a match, the transaction is processed. If it is not a match, the transaction is rejected. The TAN has now been used and will not be recognized for any further transactions. If the TAN list is compromised, the user may cancel it by notifying the bank.

  4. Digital signature - Wikipedia

    en.wikipedia.org/wiki/Digital_signature

    The user application presents a hash code to be signed by the digital signing algorithm using the private key. An attacker who gains control of the user's PC can possibly replace the user application with a foreign substitute, in effect replacing the user's own communications with those of the attacker.

  5. Distributed control system - Wikipedia

    en.wikipedia.org/wiki/Distributed_control_system

    DCSs are connected to sensors and actuators and use setpoint control to control the flow of material through the plant. A typical application is a PID controller fed by a flow meter and using a control valve as the final control element. The DCS sends the setpoint required by the process to the controller which instructs a valve to operate so ...

    Protean eGov Technologies Limited (previously NSDL e-Governance Infrastructure Limited) is an Indian technology company headquartered in Mumbai. [1] The company focuses on developing digital public infrastructure (DPI) and e-governance initiatives for various governmental bodies in India. [2]

  7. Dynamic mechanical analysis - Wikipedia

    en.wikipedia.org/wiki/Dynamic_mechanical_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 modulus.

  8. 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]

  9. Distributed source coding - Wikipedia

    en.wikipedia.org/wiki/Distributed_source_coding

    Moreover, DSC has been used in video compression for applications which require low complexity video encoding, such as sensor networks, multiview video camcorders, and so on. [ 12 ] With deterministic and probabilistic discussions of correlation model of two correlated information sources, DSC schemes with more general compressed rates have ...
