The role of the supervisor. Although a dissertation is an opportunity for you to work independently, you will usually be allocated a member of academic staff as a supervisor. Supervisors are there to help you shape your ideas and give you advice on how to conduct the research for your dissertation.
The TN device consists of the twisted nematic liquid crystal confined between two glass substrates with homogeneous planar orientation: the orientation of the director n on one substrate is rotated by 90 o with respect to n on another substrate.
A twisted-pair cable is a cable made by intertwining two separate insulated wires. There are two twisted pair types: shielded and unshielded.A Shielded Twisted Pair (STP) has a fine wire mesh surrounding the wires to protect the transmission; an Unshielded Twisted Pair (UTP) do not.Shielded cable is used in older telephone networks, as well as network and data communications to reduce outside interference.
