By means of three-dimensional numerical calculations we studied possible micromagnetic configurations in a rectangular Permalloy-like thin-film element. The parameters were chosen to be compatible with the so-called micromagnetic standard problem 1. We demonstrate that for these parameters a diamond domain pattern is the lowest energy state that replaces cross-tie patterns favorable in larger e...

We study online prediction where regret of the algorithm is measured against a benchmark defined via evolving constraints. This framework captures online prediction on graphs, as well as other prediction problems with combinatorial structure. A key aspect here is that finding the optimal benchmark predictor (even in hindsight, given all the data) might be computationally hard due to the combina...

The goal of this research is to develop performance profiles of parallel and distributed applications in order to predict their execution time under different network conditions. This paper measures the resource requirements of the NAS benchmark programs and characterizes their performance in a shared heterogeneous environment. The programs in the benchmark suite were executed on a controlled t...

Multi-tenancy in relational databases has been a topic of interest for a couple of years. On the one hand, ever increasing capabilities and capacities of modern hardware easily allow for multiple database applications to share one system. On the other hand, cloud computing leads to outsourcing of many applications to service architectures, which in turn leads to offerings for relational databas...

Abstract Blast loading and its interaction with structures is a complex phenomenon even in the simplest of cases and modelling its effects is a non-trivial task. This complexity is increased when dealing with long duration blast due to the drag loads associated with the dynamic pressure. This paper establishes a scientific benchmark for the debris distribution modelling of masonry panels as the...

A number of computer codes has been developed in laboratories worldwide to simulate electron cloud formation and dissipation in accelerators. The codes’ underlying assumptions and physical models are often different and based on alternative experimental inputs. As part of an inter-laboratory code-code and code-experiment benchmarking effort re-launched after the ECLOUD’04 workshop [4], the pres...
