Interconnection networks of degree three obtained by pruning two-dimensional tori (2013)
Journal Article
Stewart, I. (2014). Interconnection networks of degree three obtained by pruning two-dimensional tori. IEEE Transactions on Computers, 63(10), 2473-9340. https://doi.org/10.1109/tc.2013.139

We study an interconnection network that we call 3Torus(m,n) obtained by pruning the 4m x 4n torus (of links) so that the resulting network is regular of degree 3. We show that 3Torus(m,n) retains many of the useful properties of tori (although, of c... Read More about Interconnection networks of degree three obtained by pruning two-dimensional tori.

Trends in the quality of human-centric software engineering experiments--a quasi-experiment (2013)
Journal Article
Kitchenham, B., Sjoberg, D., Dyba, T., Brereton, P., Budgen, D., Host, M., & Runeson, P. (2013). Trends in the quality of human-centric software engineering experiments--a quasi-experiment. IEEE Transactions on Software Engineering, 39(7), 1002-1017. https://doi.org/10.1109/tse.2012.76

Context: Several text books and articles published between 2000 and 2002 have attempted to introduce experimental design and statistical methods to software engineers undertaking empirical studies. Objective: This paper investigates whether there has... Read More about Trends in the quality of human-centric software engineering experiments--a quasi-experiment.

Random walks which prefer unvisited edges : exploring high girth even degree expanders in linear time (2013)
Journal Article
Berenbrink, P., Cooper, C., & Friedetzky, T. (2015). Random walks which prefer unvisited edges : exploring high girth even degree expanders in linear time. Random Structures and Algorithms, 46(1), 36-54. https://doi.org/10.1002/rsa.20504

Let G = (V,E) be a connected graph with |V | = n vertices. A simple random walk on the vertex set of G is a process, which at each step moves from its current vertex position to a neighbouring vertex chosen uniformly at random. We consider a modified...

Towards understanding learning behavior patterns in social adaptive personalized e-learning systems (2013)
Presentation / Conference Contribution

Implicit user modeling has always long since played an important role in supporting personalized web-based e-learning environments and is increasingly important in other learning environments such as serious games. Its main concern is to unobtrusivel... Read More about Towards understanding learning behavior patterns in social adaptive personalized e-learning systems.
