Tuning of PID controller by bioinspired techniques

PID controllers have been extensively used for a long time for the purpose of process controls.Efficient methods for tuning of PID controllers is still a challange to designers. This project work is based on the development of PID controller for a low damping plant using Bio inspired evolutionary soft computational techniques.We have implemented Particle Swarm Optimization and Bacterial Foraging Optimization techniques to tune the parameters of the PID for a fifth order low damping plant and have done a comparative study of the performance of both the techniques

A novel group signature scheme without one way hash

The group signatures scheme was introduced by Chaum and van Heijst which allow members of a group to sign messages anonymously on behalf of the whole group. Only a designated Group Manager is able to trace the identify of the group member who issued a valid signature. The group members sign a message with their secret key gsk and produce a signature that cannot be linked to the identities of the signers without the secret key of the manager. The group manager can open the signature to recover the identities of the signers in case of any legal dispute. Group signatures have been widely used in Electronic markets where the sellers are the group members, the buyers are the veriers and the market administrator is the group manager. We aim to propose a group signature scheme that is devoid of any one-way hash function and is based upon the Integer Factorization Problem (IFP). The scheme uses the concept of safe primes to further enhance the security of the scheme. The scheme supports message recovery and hence the overload of sending the message is avoided. The scheme satisfies security properties such as Anonymity (The verier cannot link a signature to the identity of the signer), Traceability (The Group Manager can trace the identity of the signer of any valid signature), Unforgeability (A valid signature cannot be produced without the group secret keys), Exculpability (Neither the GM nor any member can produce a signature on behalf of a group member)

INVESTIGATION ON CYLINDRICAL GATE ALL AROUND (GAA) TO NANOWIRE MOSFET FOR CIRCUIT APPLICATION

Undoped cylindrical gate all around (GAA) MOSFET is a radical invention and a potential candidate to replace conventional MOSFET, as it introduces new direction for transistor scaling. In this work, the sensitivity of process parameters like channel length (Lg), channel thickness (tSi), and gate work function (φM) on various performance metrics of an undoped cylindrical GAA to nanowire MOSFET are systematically analyzed. The electrical characteristics such as on current (Ion), subthreshold leakage current (Ioff), threshold voltage (Vth) and similarly analog/RF performances like transconductance (gm), total gate capacitance (Cgg), and cut-off frequency (fT) are evaluated and studied with the variation of device design parameters. The discussion give direction towards low standby operating power (LSTP) devices as improvement in Ioff is approaching 90% in nanowire MOSFET. All the device performances of undoped GAA MOSFET are investigated through Sentaurus device simulator from Synopsis Inc
