In contrary to scaled equations, Elmer applies Full Stokes (FS) simulations,
where horizontal scales of the mesh are of similar size than vertical, leading
to a scale-up of the problem size by a factor 100. Models earlier run on a
single workstation consequently occupy 100 and more processors if FS is applied,
demanding parallel computations on clusters or Grid environments. The main...

Gene ontology can be thought of as a database of expert-based terms. The application presented utilizes the motifs that exist in already annotated protein sequences in order to model the corresponding GO terms.

The complexity of the hardware/software components, and the intricacy of their interactions, defeat attempts to build fault models only from a-priori knowledge. A black-box approach, where we observe the events to spot outliers, is appealing by its simplicity, and large body of experience in quality control. The general challenge is to detect anomalies as soon as possible. Much better...
