Abstract. Failure is an ordinary characteristic of large-scale distributed environments. Resubmission is a general strategy employed to cope with failures in grids. Here, we analyt...
Image-based modeling of semi-transparent, dynamic phenomena is a challenging task. We present an optical tomography method that uses an adaptive grid for the reconstruction of a t...
The conduct of collaborative scientific study mediated by the internet — e-Science — is giving rise to a new type of large distributed software project. This paper reports in...
This paper shows that flexibility of workflow executions, i.e., the ability to deviate from a given model on the fly and during execution, is crucial for a wide applicability of w...
We improve upon the best known upper and lower bounds on the sizes of minimal feedback vertex sets in butterflies. Also, we construct new feedback vertex sets in grids so that for...
