What are seminar topics in instrumentation and control engineering?

The Seminar topics in Instrumentation and Control Engineering could be many,

since Instrumentation itself is a very vast field.

Owing to this I tried to dialogue a little in here:

1) Transducers and Sensors.

2) Electronics measurements and Instrumentation.

3) Micro controllers and Microprocessors.

4) Signal and Sytems( Z, Nyquist t/f, Bode plots, Laplace t/f with/out Convolutions)

5) Control systems.

6) Process control and Actuators.

7) Bio Medical Instrumentation( EEG,EMG,ECG,MRI and X-ray)
