-The Math Engine reads a model description from an XML file (following the model.dtd), applies this to a trial of input timeseries and optional parameters and creates an output file, which includes timeseries, parameters, event positions etc.. The Math Engine is highly configurable and includes a powerful Plugin System for simple mathematical functions and complex mathematical algorithms as well.

+=====General=====
+The Math Engine reads a model description from an XML file (following the model.dtd), applies this to a trial of input timeseries and optional parameters and creates an output file, which includes timeseries, parameters, event positions etc.. The Math Engine is highly configurable and includes a powerful Plugin System for simple mathematical functions and complex mathematical algorithms as well. The Math Engine runs the most important functionalty of the Upperlimb software sometimes called the "Processing step".
+=====Model description=====
 The following XML Model fragment shows that simple mathematical formulae can be used directly in the model description (e.g. (LSHO+RSHO)/2.0) and that more complex algorithms e.g. a definition of a coordinate system based on the position of some markers are accessed by specific elements (e.g. <coordinatesystem/>) and configured by its attributes (e.g. Position="CLAV").
 <code xml>
+<CalcModel name="Test">
+   <Point name="ShoulderMidPoint">(LSHO+RSHO)/2.0</Point>
+   <CoordinateSystem name="Thorax"
+                     Position="CLAV"
+                     FirstAxis="CLAV-C7"
+                     DefiningAxis="(CLAV+C7)-(STRN+T10)"
+                     orientation="xyz"/>
+</CalcModel>
+</code>
+=====Model parameters=====
+The model can include externally defined parameters. If these parameters are fix for the model they are defined in a file with the name "constant.properties" in the projects subfolder with the name "Constants".
-</code>
+Subject specific parameters can be read from an ".mp"-file in the session folder or from a so called examination properties files.
+=====Notes=====
+A model is always formulated for a single time frame and it is automatically applied to each frame of the timeseries. A Nimue application can be based on a set of fix models delivered with the application which maybe can be selectable by the user. Or the application can provide a complete modelling system, where the XML model descriptions can be created and modified by the user. In this case a powerful grahical user interface (XML Multi View) is available to hide the xml code for the user.
