Choræus, Michael

f. 15.3.1774 i Vörå d. 3.6.1806 i Stockholm, Sverige Michael Choræus har gått till historien som sen upplysningstida finländsk diktare. Han publicerade sina litterära verk kring år 1800, vid sidan om sin akademiska och teologiska bana. I fråga om stil och tematik var han influerad av den samtida och likaså svenskspråkiga diktarkollegan Frans Michael Franzén. I sin samtid väckte Choræus uppseende med sin kvickhet och sitt intellekt, samt har setts som den mest begåvade finländska lyrikern i sin tid. I hans produktion ingår flytande verskonst som inte sällan tonsatts, däribland också psalmbearbetningar, samt även t.ex. tillfällesdikt och satir. Som exempel på hans dikter kan nämnas En tanke på min egen graf, Ehrensvärd. Skaldesång och Lilla Calle (utgivna i t.ex. tidningar under diktarens livstid och senare i Choræus samlade skaldestycken 1815). Biografiskt lexikon för Finland: http://www.blf.fi/artikel.php?id=2355

Antiphonarium (MS C.ö.III.20, "Michael Ericin antifonarium")

A copy of a Dominican antiphonary produced for Lutheran use in the second half of the sixteenth century. The sanctoral reflects Lutheran tastes, with St Henry, the patron of Finland, being the only non-biblical saint.

Variational Ensemble Kalman Filtering in Hydrology

The current thesis manuscript studies the suitability of a recent data assimilation method, the Variational Ensemble Kalman Filter (VEnKF), to real-life fluid dynamic problems in hydrology. VEnKF combines a variational formulation of the data assimilation problem based on minimizing an energy functional with an Ensemble Kalman filter approximation to the Hessian matrix that also serves as an approximation to the inverse of the error covariance matrix. One of the significant features of VEnKF is the very frequent re-sampling of the ensemble: resampling is done at every observation step. This unusual feature is further exacerbated by observation interpolation that is seen beneficial for numerical stability. In this case the ensemble is resampled every time step of the numerical model. VEnKF is implemented in several configurations to data from a real laboratory-scale dam break problem modelled with the shallow water equations. It is also tried in a two-layer Quasi- Geostrophic atmospheric flow problem. In both cases VEnKF proves to be an efficient and accurate data assimilation method that renders the analysis more realistic than the numerical model alone. It also proves to be robust against filter instability by its adaptive nature.
