	<h2>Results</h2>	
	For evaluating hypothesis H1 ('If both approaches perform a synchronized refactoring, 
	the results are equal.'), we used all the positive test cases (both refactorings are 
	applicable) for the refactoring pair <i>RenameAttribute;RenameField</i> for evaluating 
	whether both approaches lead to the same results. After we performed this refactoring 
	for each direction and each approach, we compared the resulting artifacts using the 
	text comparison facility in Eclipse (for Java code) and the model comparison functionality 
	provided by EMF Compare. The corresponding code and model comparisons showing no differences
	can be found here:
	<ul class="midlist">
		<li><a href="downloads/screenshots.zip" target="_blank">screenshots</a>.</li>
	</ul>
	For evaluating hypothesis H2 ('The dynamic mapping of model and code is fast enough.'), 
	we measured the time needed for dynamically mapping the corresponding elements. 
	The measurements are performed on a Mac Book Air MId 2011 machine (4 GB RAM; Intel i5-2557M 
	dual core 2.7 Ghz). The following tables show the corresponding results in microseconds.
