Materials with Dirac-type electronic band structure have recently drawn much interest. These materials revealed unique electrical, thermal and optical properties, which can be potentially used in future highspeed electronics. In this dissertation research, I investigate on two different classes of Dirac materials: graphene and topological insulators of the bismuth telluride (Bi2Te3) family. The...

A practical and effective general approach is presented for extending the useful operating frequencies and improving the performance of linear active networks realized using operational amplifiers (OA’s). This is achieved by replacing each OA in the active network by a composite operational amplifier (CNOA) constructed using N OA’s.’ The technique of generating the CNOA’s for any given N is pro...

St George Hospital, Renal Department – INTERNAL ONLY Treatment of Chronic Hypertension and Hypertensive Urgency on Haemodialysis

Acute control of blood pressure on haemodialysis (HD) should be differentiated from chronic BP control; Hypertension in HD is multi-factorial; Patients requiring total ultrafiltration volume greater than 2.5 kg may have an elevation in pre-systolic and pre-diastolic BPs; Larger fluid removals of range >10-13ml/hour/kg are associated with increased all cause and cardiovascular mortality; Both pr...

In this project the possibility of using a network of magnetometers sensing a permanent magnet for tracking has been investigated. Both the orientation and the position of the magnet have been considered. A dipole approximation of the magnetic field is used to develop two models. One of the models parametrizes the orientation with the magnetic moment vector, while the other parametrizes the ori...
