Unified Framework for Finite Element Assembly

At the heart of any finite element simulation is the assembly of matrices and vectors from discrete variational forms. We propose a general interface between problem-specific and general-purpose components of finite element programs. This interface is called Unified Form-assembly Code (UFC). A wide range of finite element problems is covered, including mixed finite elements and discontinuous Galerkin methods. We discuss how the UFC interface enables implementations of variational form evaluation to be independent of mesh and linear algebra components. UFC does not depend on any external libraries, and is released into the public domain

The Genomic HyperBrowser: inferential genomics at the sequence level

The immense increase in the generation of genomic scale data poses an unmet analytical challenge, due to a lack of established methodology with the required flexibility and power. We propose a first principled approach to statistical analysis of sequence-level genomic information. We provide a growing collection of generic biological investigations that query pairwise relations between tracks, represented as mathematical objects, along the genome. The Genomic HyperBrowser implements the approach and is available at http://hyperbrowser.uio.no

A Metadata Approach to Predicting Twitter User Geolocation

As the volume of available data created from social media grows, creating value out of this information becomes an interesting challenge. This work presents an approach to identify a users country of origin from just looking at a single tweet. The approach focuses on using only metadata, while disregarding the actual content of the tweet. This work also looks at the scalability of the approach using Naive Bayes algorithm. The experiments concludes that using metadata to predict a user geolocation is a viable approach that scales to a stable accuracy with increasing data size
