  4. TrueTime • TrueTime is a Matlab/Simulink-based simulator for real-time control systems. • Written in C++ MEX • Network block (Ethernet, CAN, TDMA, FDMA, Round Robin, Switched Ethernet, FlexRay and PROFINET) • Wireless network block (802.11b WLAN and 802.15.4 ZigBee) • 2010-07-16
TrueTime 2.0 beta 6 has been released. Added support for Network Code Machine by Sebastian Fischmeister et al. Source: http://www.control.lth.se/truetime/

  8. Network Model for Pulmonary Vascular Resistance (PVR)

  9. Key Points: • PVR is the resistance in the pulmonary vascular bed against which the right ventricle must eject blood. • To calculate the pulmonary vascular resistance, the patient monitor needs to know: 1. left atrial pressure (LAP) 2. pulmonary capillary wedge pressure (PCWP), 3. pulmonary artery pressure (PAP), and 4. cardiac output (CO). • PCWP provides an indirect estimate of LAP.

  10. State-Based Schedule:

  11. Tabular Specifications for the PVR model

  12. Key Points: Uses Table Tool implemented by Colin @ McMaster University Tabular input specifications for mode changes Table is verified using PVS tool

  13. Thank You. Any thoughts?
