To compare the outcomes of participatory and user-centered contextual design, case study methods and the Activity Checklist derived from Activity Theory are used to analyze two sy...
We present a new bicriteria approximation algorithm for the degree-bounded minimum-cost spanning tree problem: Given an undirected graph with nonnegative edge weights and degree b...
This paper provides a summary of previous work done in the area of external auditory representations of programs (known as program auralisation). A brief historical review is give...
The notion of fixed-parameter approximation is introduced to investigate the approximability of optimization problems within the framework of fixed-parameter computation. This work...
In this paper we explore the impact of the block shape on blocked and vectorized versions of the Sparse Matrix-Vector Multiplication (SpMV) kernel and build upon previous work by ...
