27	27	//» Dienste.// Algorithmen und Meta Layout müssen den Anwendern zugänglich gemacht werden, damit ein Nutzen daraus entsteht. Dazu müssen wir verschiedenste graphische Frameworks mit vorhandenen Layout-Bibliotheken integrieren und eine Reihe von Werkzeugen entwickeln, mit denen die Verfügbarkeit unserer Lösungen gesteigert wird. Hierzu gehört z.B. die Unterstützung von Standard-Graphenformaten sowie ein Web-Service für automatisches Layout.

	29	+* **Evaluate Impact of Reversing Edges on Humans** (Master)
	30	+Reversing edges during the layer assignment problem as suggested by the previous topic may have a negative impact on the readability of diagram. User-studies should be carefully planned and conducted to answer two questions: which edges are naturally reversed by humans and does reversing too many edges worsen comprehensibility?
	31	+* **Node Placement With a Focus on Compactness** (Master)
	32	+Node placement algorithms often try to draw as many edges as straight lines as possible. However, that usually results in less compact diagrams. The focus of this topic would be to devise or adapt a node placement algorithm that tries to strike a balance between straightness and compactness.

	36	+* **Interactive Constraint Creation and Application in Automatic Layout **(Bachelor, Master)
	37	+Evaluate options how to create constraints on the layout like "Node x should be placed at position y" and how to implement this in the current layout algorithms. Assess how such constraints can be persisted within the model.
	38	+* **Force Based Drawing with Port Constraints** (Master)
	39	+Develop methods for integrating port constraints in force-based drawing approaches. The resulting node placement shall be evaluated using an edge router such as [[libavoid>>url:http://www.adaptagrams.org/||shape="rect"]] on the model library of [[Ptolemy>>url:http://ptolemy.eecs.berkeley.edu/||shape="rect"]].
	40	+
	41	+\\
	42	+
	43	+* **Improved Spline Edge Routing **(Master)
	44	+Our layer-based layout algorithm is capable to route edges as splines. Evaluate the results using state machine diagrams, identify possible improvements and develop solutions to address these.
	45	+* **Orthogonal "Edge Bundling"** (Bachelor, Master)
	46	+Implement and evaluate strategies for orthogonal edge bundling within our layer-based layout algorithm.
	47	+\\
	48	+* **Force-directed Methods for State Machine Layout** (Master)
	49	+We currently use layer-based methods to layout SCCharts, a state machine dialect. The goal of this topic is to evaluate and implement force-directed methods to lay out SCCharts. Hard requirements are a proper placement of edge labels, proper routing of edges, and being able to specify the relative positioning of certain nodes to each other.
	50	+* **Routing of Self-Loops** (Master)
	51	+Self-loops are an integral part of many diagram types, for instance, of state diagrams and dataflow diagrams. Properly routing self-loops is not as easy as one may think. The task of this topic is to evaluate and implement different strategies to route self-loops for three edge routing styles: polyline, orthogonal, and splines. Labels of self loops are to be considered as well.

38	38	Use pragmatics concepts (automatic layout, focus & context) for exploring/visualizing control flow graphs and specific paths, eg. as computed by OTAWA WCET analysis tool, eg. using KLighD.
	64	+* **Generate signal flow graphs from finished module descriptions (Bachelor)**
	65	+Use pragmatics concepts to parse YAML data and generate browsable signal flow diagrams for an audio application using KLighD. Might also include building an Xtext-based editor to write the YAML files in the first place and help highlight problems. (In conjunction with [[sonoware GmbH>>url:https://www.sonoware.de/en/||shape="rect"]])
39	39	* **Use signal flow graphs for parameterizing / debugging audio system configurations (Master)**
40	40	The configuration of how signals are routed and how signal processors are configured in an audio system is a complex task. Make configuration and debugging easier by providing a visualization of the current configuration. Also, research what will help developers and users find configuration problems. The resulting software can be integrated into an existing Python-based configuration application, or be developed as a standalone tool that communicates with the audio system through Ethernet.
