JCCD

Benjamin Biegel, Stephan Diehl
2010 Proceedings of the IEEE/ACM international conference on Automated software engineering - ASE '10  
Code clone detection is an enabling technology for plenty of applications, each having different requirements for a code clone detector. In the tool demonstration we present JCCD, a code clone detection API, which is based on a pipeline model. By combining and parameterizing predefined API components as well as by adding new components, the pipeline model does not only facilitate to build new custom code clone detectors, but also to parallelize the detection process.

Code Tagging as a Social Game

Benjamin Biegel, Fabian Beck, Benedikt Lesch, Stephan Diehl
2014 2014 IEEE International Conference on Software Maintenance and Evolution  
Keywords or tags summarize documents on an abstract level and can also be used for describing code fragments. They might be leveraged for retrieving features of a software system, understanding program functionality, or providing additional context. While automatic approaches at best are only able to retrieve information that is already contained in the source code, manual tagging could add valuable extra information from qualified expertise of the developers. However, tagging code is tedious.
more » ... o make code tagging more fun, we introduce a social gamification approach: developers independently tag code fragments and are rewarded if their solutions conform to the solution of other developers. We implemented the game as a Facebook plug-in. A pilot user study suggests that the game mechanics are motivating and promote the proposition of reasonable tags.

RegViz: visual debugging of regular expressions

Fabian Beck, Stefan Gulan, Benjamin Biegel, Sebastian Baltes, Daniel Weiskopf
2014 Companion Proceedings of the 36th International Conference on Software Engineering - ICSE Companion 2014  
Regular expressions are a widely used programming technique, but seem to be neglected by software engineering research. Encoding complex string parsing in a very compact notation, their complexity and compactness, however, introduce particular challenges with respect to program comprehension. In this paper, we present RegViz, an approach to visually augment regular expressions without changing their original textual notation. The visual encoding clarifies the structure of the regular

We implemented RegViz as a Web-based tool for JavaScript regular expressions. Expert feedback suggests that the approach is intuitive to apply and increases the readability of regular expressions.

Predictive control of demand side units participating in the primary frequency reserve market

Benjamin Biegel, Jakob Stoustrup, Palle Andersen, Lars Henrik Hansen
2013 2013 American Control Conference  
We consider an aggregator controlling a mixed portfolio of conventional power generators and demand side units. The generators are controllable within certain power and ramp limitations while the demand side units are characterized by flexible consumptions and therefore can be treated as energy storages of limited capacity. We address the problem of reducing the load on the conventional generators by letting the flexible consumers participate in the provision of primary frequency reserve. In

In this work, we design an aggregator control strategy based on closed-loop model predictive control. The controller is able to mobilize the flexible consumers ahead of time such that we are able to reduce the load on the conventional generators by more extensive use of the demand side units. is with DONG Energy (largest Danish power producer), Copenhagen, Denmark; LARHA@dongenergy.dk.

Electricity market optimization of heat pump portfolio

Benjamin Biegel, Palle Andersen, Tom S. Pedersen, Kirsten Molgaard Nielsen, Jakob Stoustrup, Lars Henrik Hansen
2013 2013 IEEE International Conference on Control Applications (CCA)  
We consider a portfolio of domestic heat pumps controlled by an aggregator. The aggregator is able to adjust the consumption of the heat pumps without affecting the comfort in the houses and uses this ability to shift the main consumption to hours with low electricity prices. Further, the aggregator is able to place upward and downward regulating bids in the regulating power market based on the consumption flexibility. A simulation is carried out based on data from a Danish domestic heat pump

The Order of Things: How developers sort fields and methods

Benjamin Biegel, Fabian Beck, Willi Hornig, Stephan Diehl
2012 2012 28th IEEE International Conference on Software Maintenance (ICSM)  
In source code files, fields and methods are arranged in linear order. Modern programming languages such as Java do not constrain this order-developers are free to choose any sequence. In this paper we examine the largely unexplored strategies developers apply for ordering fields and methods: First, we use visualization to explore different ordering criteria within two open source Java projects. Second, we verify our observations in a metric-based analysis on an extended set of 16 projects.
more » ... d, we present the results of a survey that reflects the opinion and applied ordering strategies of 52 developers. 87% of the participants agreed that ordering of fields and methods is meaningful or important. Our results suggest that there exists a set of criteria repeatedly used for ordering. Among these, the categories defined in the official Java Code Conventions appear to be the primary ordering criterion. However, in the individual strategies of the participants of the survey, we identified 15 ordering criteria additional to the five criteria we considered in the empirical analysis.
