Using differential pressure sensor to measure nitrous oxide level in a tank
PublikacjaA method for measuring the level of liquid nitrous oxide oxidizer in a hybrid rocket motor oxidizer tank is proposed. Presented approach is more accurate than the most commonly used method of this measurement, which employs weighting of the whole sounding rocket or an oxidizer tank. In our solution we use a differential pressure sensor to measure the change of pressure at the bottom of an oxidizer tank in comparison to the pressure...

Spurring the community involvement in planning - lessons from post-socialist cities
PublikacjaPublic participation and community involvement in planning processes is – in general – not a new topic for contemporary planners. But in many parts of the world – including the post-socialist countries like Poland or Russia – we can still face the lack of understanding of importance of proper community involvement in planning and development processes. Situation in these countries is significantly different from both highly-developed...
