Quflow & Perfeco

Quflow has experience with system simulation and system identification for aspects that has mattered in radio and power design for vehicles and mobile devices: user perception, power consumption scenarios, link budgets with fading, thermal design, waveguides, signal integrity, noise, water cycles etc etc. Most of these use quickly crafted models for specific needs. Here are links to sites which cover similar topics interactively online:

• PhET: Interactive simulators by University of Colorado at Boulder (http://phet.colorado.edu/en/simulations/category/new).
• Virtual Physics Laboratory by CoLoS (http://www.phy.ntnu.edu.tw/ntnujava).
• Electromagnetics and Waves by EE Circle (http://www.eecircle.com/applets/si_emc.html).
