The implementation of Hierarchical Timed Petri Net (HTPN) in our system modelling tool yields a hierarchical analysis method, namely a Hierarchical Reachability State Diagram (HRSD). A Reachability State Diagram (RSD) can be generated for each subnet, and the number of tokens in each H-Block are also record in the state markings. Since the intention of using a HTPN hierarchical representation i...

Flywheel systems based on fibre composites can have power densities which are significantly better than for electrochemical batteries. Hence, they have considerable potential for use as peak power buffers in drive-trains for electric and hybrid vehicles. As the rotational speed is increased, however, bearing friction power loss and iron losses in the motor/generator become more significant. Thu...

With the increasing need to incorporate more complex mixed-signal controller for switched mode power supplies, CMOS compatibility becomes a very important consideration for monolithic DC-DC converters. This paper examines the different power output stage designs and identifies the key device characteristics such as onresistance, gate capacitance, switching speed that ensure optimized power conv...

The flange climb derailment is one of the cause of derailment for a typical switch. The derailment for the switch is a complex phenomenon since the contact area is changing dynamically. The contact angle between the wheel flange and the switch point is investegated in terms of the risk on the derailment. The contribution of this study is proving that UIC716R standard recommendation about the sw...
