Quadrature amplitude modulation (QAM) is a modulation scheme in which two sinusoidal carriers,
one exactly 90 degrees out of phase with respect to the other, are used to transmit data over
a given physical channel. One signal is called the I signal, and the other is called the Q signal.
Because the orthogonal carriers occupy the same frequency band and differ by a 90 degree phase
shift, each can be modulated independently, transmitted over the same frequency band, and
separated by demodulation at the receiver. For a given available bandwidth, QAM enables data
transmission at twice the rate of standard pulse amplitude modulation (PAM) without any degradation
in the bit error ratio (BER).

AES
ES is a symmetric block cipher.
The same key is used to encrypt and decrypt the message.
The plain text and the cipher text are the same size.
The Aes algorithm works as follows:
Convert to state array: This step consists of conversion on the matrix onto a state array operating with the sbox.
Transformations (and their inverses)
AddRoundKey: Computing the round key for each round.
SubBytes: Substituting by bytes from Sbox.
ShiftRows: Shifting of rows.
MixColumns: Exor operation on columns.
Key Expansion: Expanding the key to be used on next round.

Control-of-VSC-HVDC-for-wind-power
North of Norway has extremely good conditions for wind power generation. As the existing main
grid will not be able to integrate all the wind parks, the alternative to build a new corridor with
multi-terminal HVDC Light North of Norway to Middle of Norway, is under study.
HVDC Light is more and more concerned recently to improve power system stability due to its
supreme controllability. The thesis will be directed towards investigating the possible problems to
be encountered in an HVDC Light installation. A platform for the control of HVDC Light based on
the vector control principle will be first established. With a good understanding of this control
platform, the model will then be tested under several circuit conditions, to test the capability and
robustness of the controller to handle these situations.
