In this thesis we are concerned with constructing algorithms that address problems of biological relevance. This activity is part of a broader interdisciplinary area called computational biology, or bioinformatics, that focuses on utilizing the capacities of computers to gain knowledge from biological data. The majority of problems in computational biology(More)
Diierent way of implementing and designing arithmetic functions for 16/32 bit integers in FPGA technology are studied. This also includes a comparison of four diierent design methods. The results are used to increase the overall system performance in a dedicated 3D image analysis prototype system by moving a vector length calculation from software to(More)

Computing local alignments is used to identify similar regions within highly dissimilar sequences. It has a wide variety of uses, especially within Bioinfor-matics for analysing DNA, RNA or protein sequences. Therefore many different solutions have been presented in the past with the intent of reducing the time needed to identify local alignments, as naïve(More)
Phylogenetic trees are used in the interdisciplinary field of bioinformatics to relate and classify species according to evolutionary history. Constructing large trees is infeasible because the search space on trees is very large. As a result, supertree methods have been the focus of much research. By building trees from smaller, already constructed trees,(More)
– The European COUNT project exploits two complementary single electron tunneling (SET) devices for use in electrical current metrology: a single electron pump as a current source and a single electron counter as a current meter. An electron pump has been developed with on-chip resistors in order to suppress cotunneling. The intended accuracy is 1 ppm for a(More)
