```
org.jscience.physics.amount.Amount<? extends javax.measure.quantity.Quantity> calculateDistance(IDataStream<org.palladiosimulator.measurementframework.TupleMeasurement> s1,
                                                                                                IDataStream<org.palladiosimulator.measurementframework.TupleMeasurement> s2)
```
    This class forwards calculation parameters and is responsible for individual UI error handling of the extension.
    
    Parameters:
    
    s1 - First stream of measurement to compare.
    
    s2 - Second stream of measurement to compare.
    
    Returns:
    
    Return a generic Amount which can contain any Quantity. Returns null, if calcuation couldn't be executed.
